About Us

Staying abreast of new technology and diagnostic as well as treatment options for our patients is a high priority at Baylor Jack and Jane Hamilton Heart and Vascular Hospital. Our goal is to develop and be involved in advanced research of the highest integrity that will allow our patients to participate in and benefit from innovative heart and vascular discoveries. Research is the backbone and first step in defining patient care. The 75-plus trials we are currently running are investigating many areas, including an anticoagulant that does not require INR bloodwork, genes and angina, atrial fibrillation, and stenting of the left main coronary artery.

The physicians on our medical staff and clinical staff members have been published in numerous journals and books, on topics ranging from atrial septal defects to congestive heart failure to angiography. Recent articles are included below:

Efficacy and effectiveness of on- versus off-pump coronary artery bypass grafting: A meta-analysis of mortality and survival.

Filardo G, Hamman BL, da Graca B, Sass DM, Machala NJ, Ismail S, Pollock BD, Collinsworth AW, Grayburn PA.
Despite many studies comparing on- versus off-pump coronary artery bypass graft (CABG), there is no consensus as to whether one of these techniques offers patients better outcomes.

Novel Cardiac Coordinate Modeling System for Three-Dimensional Quantification of Inflow Cannula Malposition of HeartMate II LVADs.

Lima B, Dur O, Chuang J, Chamogeorgakis T, Farrar DJ, Sundareswaran KS, Felius J, Joseph SM, Hall SA, Gonzalez-Stawinski GV.
Optimal function of left ventricular assist devices (LVADs) depends on proper alignment of the inflow cannula (IC). Quantitative guidelines for IC angulation are lacking because of variation in cardiac geometry and difficulty in analyzing three-dimensional (3D) cannula orientation relative to the left ventricle (LV). Based on contrast-enhanced computed tomography images from five normal and five clinically malpositioned IC cases in patients with HeartMate II LVADs, we developed a method for 3D quantification of IC malpositioning. Using Mimics image software (Materialise, Leuven, Belgium), the native heart, major arteries, and LVAD were segmented to create patient-specific 3D models, allowing LV cavity volume and long-axis length to be measured directly. The deviation of the IC was quantified in a cylindrical coordinate system at the IC insertion point relative to the mitral valve and septum, and IC occlusion was assessed by the distance between cannula inlet and the proximal endocardium. Compared with normal cases, patients with malpositioned pumps had shorter LV length (p = 0.03) and reduced pump pocket depth (p = 0.009). Malpositioned pumps may experience greater obstruction by the nearby myocardium. This quantitative 3D modeling tool may help identify different modes of pump malalignment and migration and may facilitate preoperative planning and minimally invasive approaches via virtual LVAD implantation.

Utilization of high donor sequence number grafts in cardiac transplantation.

Squiers JJ, DiMaio JM, Sarcino G, Qin H, Felius J, Chamogeorgakis T, MacHannaford JC, Rafael AE, Kale P, Joseph SM, Hall SA, Gonzalez-Stawinski GV, Lima B.
Donor sequence number (DSN) represents the number of candidates to whom a graft was offered and declined prior to acceptance for transplantation. We sought to investigate the outcomes of patients receiving high DSN grafts. Consecutive isolated adult cardiac transplantations performed at a single-center were reviewed. Recipients were grouped into standard (?75th percentile) DSN and high (>75th percentile) DSN. A previously validated donor risk index was used to quantify the risk associated with donor grafts, and recipient outcomes were assessed. Overall, 254 patients were included: 194 standard DSN (range 1-79) and 60 high DSN (range 82-1723). High DSN grafts were harvested at greater distance (P < .001) with increased ischemia time (P < .001), resulting in a modest increase in donor risk index (1 point median difference, P = .014). High DSN recipients were less frequently listed as UNOS status 1A (P < .001). Despite a nonsignificant trend toward increased in-hospital/30-day mortality in high DSN recipients, there were no differences in primary graft dysfunction or 1-year survival (high DSN 89% vs standard DSN 88%, P = .82). After adjustment for risk factors, high DSN was not associated with increased 1-year mortality (hazard ratio 1.18, 95%-CI 0.54-2.58, P = .68).

Major Adverse Renal and Cardiac Events Following Angiography and Cardiac Surgery.

Tecson KM, Brown D, Choi JW, Feghali G, Gonzalez-Stawinski GV, Hamman BL, Hebeler R, Lander SR, Lima B, Potluri S, Schussler JM, Stoler RC, Velasco C, McCullough PA.
Patients at high risk for developing post-procedural complications may receive iodixanol, an iso-osmolar contrast, during coronary angiography to minimize the risk of renal toxicity. For those who additionally require cardiac surgery, the wait-time between angiography and surgery may be a modifiable factor capable of mitigating poor surgical outcomes; however, there have been inconsistsent reports regarding the optimal wait-time. We sought to determine the effects of wait time between angiogram and cardiac surgery, as well as contrast induced acute injury (CI-AKI) on the development of major adverse renal and cardiac events (MARCE).

Asymptomatic Ascending Aorta Aneurysm with Severe Aortic Regurgitation Caused by Multiple Intimal-Medial Tears Unassociated with Aortic Dissection.

Velasco CE, Hashemi H, Roullard CP, MacHannaford J, Roberts WC.
A 62-year-old man was found to have an asymptomatic ascending aortic aneurysm (6.6?cm) associated with severe aortic regurgitation. Operative resection of the wall of the aneurysm disclosed its cause to be multiple healed intimal-medial tears without dissection involving a previously normal aorta. The concept of an intimal-medial tear unassociated with aortic dissection is a poorly recognized entity and these tears appear to be asymptomatic and after the aortic tearing lead to aneurysmal formation.

Can use of an administrative database improve accuracy of hospital-reported readmission rates?

Edgerton JR, Herbert MA, Hamman BL, Ring WS.
Readmission rates after cardiac surgery are being used as a quality indicator; they are also being collected by Medicare and are tied to reimbursement. Accurate knowledge of readmission rates may be difficult to achieve because patients may be readmitted to different hospitals. In our area, 81 hospitals share administrative claims data; 28 of these hospitals (from 5 different hospital systems) do cardiac surgery and share Society of Thoracic Surgeons (STS) clinical data. We used these 2 sources to compare the readmissions data for accuracy.

Comparison of Clinical Characteristics, Complications, and Outcomes in Recipients Having Heart Transplants <65 Years of Age Versus ?65 Years of Age.

Jamil A, Qin H, Felius J, Saracino G, Rafael AE, MacHannaford JC, Gonzalez-Stawinski GV, Lima B.
Advanced recipient age remains a limiting factor for heart transplant candidacy, with many centers reluctant to transplant older patients. Here, we report our experience with recipients aged ?65 years compared with younger recipients in terms of baseline characteristics, intraoperative and immediate postoperative experiences, and post-transplant morbidity and survival. The main study outcome was primary graft dysfunction (PGD), which has not been widely studied in this population. Donor and recipient data from 255 heart transplantations performed between 2012 and 2016 were reviewed. Seventy (27%) recipients were ?65 years and 185 were younger. The older group had a higher frequency of ischemic cardiomyopathy and more frequently had a previous sternotomy than the younger recipients (all p?<0.007). We found no significant differences in post-transplant morbidity (intensive care unit and hospital stay, pneumonia, infections, reoperation for bleeding, stroke, renal failure, or in-hospital mortality; all p?>0.12). One-year survival was also similar in the 2 groups (p?=?0.88). The incidence of moderate or severe PGD was lower in the older group (6%) than in the younger group (16%; p?=?0.037). Multivariate logistic regression found pretransplant creatinine and donor undersizing by predicted heart mass to be predictors of moderate to severe PGD, whereas recipient age ?65 years was identified as protective against PGD in this cohort. In conclusion, our study showed comparable survival and outcomes in recipients ?65 years of age with otherwise similar nutritional status and body mass composition.

Prospective Assessment of Frailty Using the Fried Criteria in Patients Undergoing Left Ventricular Assist Device Therapy.

Joseph SM, Manghelli JL, Vader JM, Keeney T, Novak EL, Felius J, Martinez SC, Nassif ME, Lima B, Silvestry SC, Rich MW.
Frail patients are more prone to adverse events after cardiac surgery, particularly after implantation of left ventricular assist devices. Thus, frailty assessment may help identify patients unlikely to benefit from left ventricular assist device therapy. The purpose was to establish a suitable measure of frailty in adults with end-stage heart failure. In a prospective cohort of 75 patients (age 58?±?12 years) with end-stage heart failure, we assessed the association between frailty (5-component Fried criteria) and the composite primary outcome of inpatient mortality or prolonged length of stay, as well as extubation status, time on ventilator, discharge status, and long-term mortality. Fried frailty criteria were met in 44 (59%) patients, but there was no association with the primary outcome (p?=?0.10). However, an abridged set of 3 criteria (exhaustion, inactivity, and grip strength) was predictive of the primary outcome (odds ratio 2.9, 95% confidence interval 1.1 to 7.4), and of time to extubation and time to discharge. In patients with advanced heart failure, the 5-component Fried criteria may not be optimally sensitive to clinical differences. In conclusion, an abridged set of 3 frailty criteria was predictive of the primary outcome and several secondary outcomes, and may therefore be a clinically useful tool in this population.

Impact of Accurate 30-Day Status on Operative Mortality: Wanted Dead or Alive, Not Unknown.

Ring WS, Edgerton JR, Herbert M, Prince S, Knoff C, Jenkins KM, Jessen ME, Hamman BL.
Risk-adjusted operative mortality is the most important quality metric in cardiac surgery for determining The Society of Thoracic Surgeons (STS) Composite Score for star ratings. Accurate 30-day status is required to determine STS operative mortality. The goal of this study was to determine the effect of unknown or missing 30-day status on risk-adjusted operative mortality in a regional STS Adult Cardiac Surgery Database cooperative and demonstrate the ability to correct these deficiencies by matching with an administrative database.

Clinical Relevance of Baseline TCP in Transcatheter Aortic Valve Replacement.

Sannino A, Stoler RC, Hebeler RF, Szlerip M, Mack MJ, Grayburn PA.
Significant thrombocytopenia (TCP) commonly occurs in seriously ill patients and after open-heart surgery, possibly as a result of cardiopulmonary bypass, use of intraaortic balloon counterpulsation, sepsis, and post-transfusion purpura. However, even severe TCP has not been clearly linked to a significant worsening in outcomes after surgical aortic valve replacement (SAVR). Transcatheter aortic valve replacement (TAVR) is the standard of care in high-risk and intermediate-risk patients with symptomatic severe aortic stenosis (AS). Current evidence suggests that acquired TCP occurring after TAVR may be due to thienopyridine use and extracorporeal circulatory support, and may be associated with adverse outcomes. However, few data exist regarding clinical outcomes associated with baseline TCP in patients undergoing TAVR. In a single small study, moderate-severe TCP was not associated with mortality, although the study was underpowered. Given that TAVR is most often performed in elderly subjects, many of whom are also frail and have baseline TCP, the aim of this study was to evaluate the effect of baseline TCP on clinical outcomes after TAVR.

HeartMate II Left Ventricular Assist Device Pump Exchange: A Single-Institution Experience.

Shaikh AF, Joseph SM, Lima B, Hall SA, Malyala R, Rafael AE, Gonzalez-Stawinski GV, Chamogeorgakis T.
Left ventricular assist devices (LVADs) have revolutionized the treatment of patients with end-stage heart failure. These devices are replaced when pump complications arise if heart transplant is not possible. We present our experience with HeartMate II (HMII (Thoratec, Plesanton, California, United States)) LVAD pump exchange.

Rational Heart Transplant From a Hepatitis C Donor: New Antiviral Weapons Conquer the Trojan Horse

Gottlieb RL, Sam T, Wada SY, Trotter JF, Asrani SK, Lima B, Joseph SM, Gonzalez-Stawinski GV, Hall SA. Hearts from donors with hepatitis C virus (HCV) are underutilized for orthotopic heart transplantation (HT) owing to post-transplantation risks, including increased recipient mortality and coronary allograft vasculopathy. New highly effective direct-acting antiviral agents (DAAs) that target multiple steps in the HCV replication life cycle could transform cardiac transplant outcomes after donor-derived HCV transmission.

Report From the American Society of Transplantation Conference on Donor Heart Selection in Adult Cardiac Transplantation in the United States.

Kobashigawa J, Khush K, Colvin M, Acker M, Van Bakel A, Eisen H, Naka Y, Patel J, Baran DA, Daun T, Luu M, Olymbios M, Rogers J, Jeevanandam V, Esmailian F, Pagani FD, Lima B, Stehlik J.
Cardiac transplantation remains the only definitive treatment for end-stage heart failure. Transplantation rates are limited by a shortage of donor hearts. This shortage is magnified because many hearts are discarded because of strict selection criteria and concern for regulatory reprimand for less-than-optimal posttransplant outcomes. There is no standardized approach to donor selection despite proposals to liberalize acceptance criteria. A donor heart selection conference was organized to facilitate discussion and generate ideas for future research. Participants debated misconceptions and established agreement on donor and recipient risk factors for donor selection and identified the components necessary for a future donor risk score. With agreement on the most important donor and recipient risk factors, it is anticipated that a consistent approach to donor selection will improve rates of heart transplantation.

Comparison of Outcomes of Operative Therapy for Acute Type A Aortic Dissections Provided at High-Volume Versus Low-Volume Medical Centers in North Texas.

Arsalan M, Squiers JJ, Herbert MA, MacHannaford JC, Chamogeorgakis T, Prince SL, Hamman BL, Knoff C, Moore DO, Harrington KB, DiMaio JM, Mack MJ, Brinkman WT.
Immediate surgery is standard therapy for acute type A aortic dissections (TAAD). Because of its low incidence, many smaller cardiac surgery programs do not routinely perform this procedure because it may negatively affect outcomes. Many high-risk, low-volume (LV) surgical procedures are now preferentially performed in reference centers. We compared the outcomes of surgery for TAAD in high-volume (HV) and LV centers in a single metropolitan area to determine the optimal setting for treatment.

Right atrial thrombus and its causes, complications, and therapy.

Benjamin MM, Afzal A, Chamogeorgakis T, Feghali GA.
A 70-year-old man who presented with dyspnea and intermittent chest pain was found to have a large free-floating right atrial thrombus on two-dimensional echocardiogram. Atriotomy was performed, and an 18-cm-long thrombus was removed from the right atrium and inferior vena cava. Postoperatively, the patient developed cardiogenic shock treated by intravenous vasopressor agents and extracorporeal membrane oxygenation. The postoperative course was also complicated by bilateral pulmonary emboli requiring pulmonary artery thrombectomy. Right atrial thrombus is an underdiagnosed condition with a high mortality rate. The best management modality has not yet been established.

Ambulatory extracorporeal membrane oxygenation with subclavian venoarterial cannulation to increase mobility and recovery in a patient awaiting cardiac transplantation.

Jacob S, MacHannaford JC, Chamogeorgakis T, Gonzalez-Stawinski GV, Felius J, Rafael AE, Malyala RS, Lima B.
Venoarterial extracorporeal membrane oxygenation (ECMO) can provide temporary cardiopulmonary support for patients in hemodynamic extremis or refractory heart failure until more durable therapies-such as cardiac transplantation or a left ventricular assist device-can be safely implemented. Conventional ECMO cannulation strategies commonly employ the femoral artery and vein, constraining the patients to the supine position for the duration of ECMO support. We have recently adopted a modified cannulation approach to promote patient mobility, rehabilitation, and faster recovery and to mitigate complications associated with femoral arterial cannulation, such as limb ischemia and compartment syndrome. This technique involves cannulation of the subclavian artery and vein. The current case report details our recent experience with this approach in a critically ill patient awaiting cardiac transplantation.

One-Year Outcomes of Transcatheter Aortic Valve Replacement in Patients With End-Stage Renal Disease.

O'Hair DP, Bajwa TK, Chetcuti SJ, Deeb GM, Stoler RC, Hebeler RF, Maini B, Mumtaz M, Kleiman NS, Reardon MJ, Li S, Adams DH, Watson DR, Yakubov SJ, Popma JJ, Petrossian G.
Early mortality in patients with ESRD is comparable to previously published data on extreme-risk patients without ESRD, but our data suggest a higher mortality rate at 1 year for ESRD patients, likely due to comorbid conditions. Stroke and major vascular injury are infrequent, and improved valve hemodynamics are maintained at 1 year.

The incidence, risk factors, and outcomes associated with late right-sided heart failure in patients supported with an axial-flow left ventricular assist device.

Rich JD, Gosev I, Patel CB, Joseph S, Katz JN, Eckman PM, Lee S, Sundareswaran K, Kilic A, Bethea B, Soleimani B, Lima B, Uriel N, Kiernan M, Evolving Mechanical Support Research Group (EMERG) Investigators.
Early right-sided heart failure (RHF) after left ventricular assist device (LVAD) implantation is associated with increased mortality, but little is known about patients who develop late RHF (LRHF). We evaluated the incidence, risk factors, and clinical impact of LRHF in patients supported by axial-flow LVADs.

Application of the International Society for Heart and Lung Transplantation (ISHLT) criteria for primary graft dysfunction after cardiac transplantation: outcomes from a high-volume centre†.

Squiers JJ, Saracino G, Chamogeorgakis T, MacHannaford JC, Rafael AE, Gonzalez-Stawinski GV, Hall SA, Lima B.
A standardized definition for primary graft dysfunction (PGD) after cardiac transplantation was recently proposed by the International Society of Heart and Lung Transplantation (ISHLT). We sought to characterize the outcomes associated with and identify risk factors for PGD following cardiac transplantation using these criteria at a high volume centre.

Transradial artery (TRA) approach is associated with fewer vascular complications and reduced mortality in patients at high risk compared with transfemoral approach (TFA). The objective of our study was to compare the characteristics and outcomes of patients who had coronary angiography by TRA and TFA over the course of hospital implementation of this approach.

Goal-Directed Heart Failure Care in Patients With Chronic Kidney Disease and End-Stage Renal Disease

Peter A McCullough, MD, MPH, Aasim Afzal, MD, MBA, Parag Kale, MD
Investigators have long recognized that renal function and cardiac performance are integrally linked through hemodynamic, neural, humoral, cell signaling, proteomic, and metabolomic pathways (1). Among risk factors for the development of heart failure (HF), chronic kidney disease (CKD) is the most powerful because it contributes to the three fundamental mechanisms of left ventricular failure: 1) pressure overload; 2) volume overload; and 3) cardiomyopathy (2). When CKD progresses to end-stage renal disease (ESRD), these three mechanisms driving HF become more difficult to control because patients undergoing dialysis have on average higher blood pressures; poor volume control only partially addressed by thrice weekly hemodialysis in most cases; and a well-described form of cardiomyopathy characterized by severe left ventricular hypertrophy, marked cardiac fibrosis, reduced capillary density, and calcific deposits on the mitral and aortic valves (3). None of the goal-directed medical or device therapies proven to reduce HF-related hospitalization and cardiovascular death in the general population with HF have been demonstrated to be effective in patients with ESRD (4).

A specialized training regimen was designed specifically for his needs, and he was able to resume his life as a commercial pilot.

An alternative approach to prescribing sternal precautions after median sternotomy, "Keep Your Move in the Tube"

Jenny Adams, PhD, Ana Lotshaw, PT, PhD, CCS, Emelia Exum, PT, DPT, Mark Campbell, BSc, MSc, Cathy B. Spranger, DrPH, Jim Beveridge, RN, PCCN, Shawn Baker, PT, DPT, MS, Stephanie McCray, RN, Tim Bilbrey, MBA, Tiffany Shock, BS, Anne Lawrence, RN, Baron L. Hamman, MD, Jeffrey M. Schussler, MD
Traditional sternal precautions, given to sternotomy patients as part of their discharge education, are intended to help prevent sternal wound complications. Our research team performed a series of studies that measured the forces exerted during various common activities and their relationship to the sternum. The alternative approach that we introduce applies standard kinesiological principles and teaches patients how to perform load-bearing movements in a way that avoids excessive stress to the sternum.

HeartMate II Left Ventricular Assist Device Pump Exchange: A Single-Institution Experience.

Shaikh AF, Joseph SM, Lima B, Hall SA, Malyala R, Rafael AE, Gonzalez-Stawinski GV, Chamogeorgakis T.
Left ventricular assist devices (LVADs) have revolutionized the treatment of patients with end-stage heart failure. These devices are replaced when pump complications arise if heart transplant is not possible. We present our experience with HeartMate II (HMII (Thoratec, Plesanton, California, United States)) LVAD pump exchange.

Using extracorporeal membrane oxygenation support preoperatively and postoperatively as a successful bridge to recovery in a patient with a large infarct-induced ventricular septal defect.

Jacob S, Patel MJ, Lima B, Felius J, Malyala RS, Chamogeorgakis T, MacHannaford JC, Gonzalez-Stawinski GV, Rafael AE.
Rupture of the ventricular septum during acute myocardial infarction usually occurs within the first week. The event is usually followed by low cardiac output, heart failure, and multiorgan failure. Despite the many advances in the nonoperative treatment of heart failure and cardiogenic shock, including the intra-aortic balloon pump and a multitude of new inotropic agents and vasodilators, these do not supplant the need for operative intervention in these critically ill patients. This article describes the successful use of extracorporeal membrane oxygenation support as a bridge to recovery postoperatively in a patient with a large infarct-produced ventricular septal defect.

Comparison of Characteristics of Patients Undergoing Heart Transplantation at the Same Hospital in Two Different Time Periods (1997-2012 and 2013-2015).
