Summary: This research study is investigating whether completing breathing exercises before surgery helps heart transplant patients recover after surgery. Previous studies have shown that breathing exercises can improve breathing, cough, and swallow function in patients with other diseases/conditions. The current study will investigate the impact of a preoperative respiratory muscle strength training progr...

Summary: Cardiac allograft vasculopathy (CAV) is a common complication affecting heart transplant patients. This condition causes narrowing of the heart arteries leading to graft dysfunction. Surveillance for CAV is vital; however an ideal approach has not been established. The goal of this study is to assess whether noninvasive positron emission tomography (PET) based surveillance is non-inferior to invas...

Summary: Cardiac allograft vasculopathy is a common complication affecting heart transplant patients. This condition causes narrowing of the heart arteries leading to graft dysfunction. The research team is investigating whether early antiplatelet therapy post heart transplant can prevent the development of CAV. This study will determine the feasibility of a large multicenter randomized placebo-controlled ...

Summary: This is an open label Comparative Effectiveness Research (CER) study in which patients will be randomized at the site level to Prospera surveillance or EMB surveillance in a 2:1 ratio (Prospera to EMB) at each site. Subjects will be enrolled into the study while under evaluation for heart transplantation or on the transplant waiting list prior to heart transplantation. All subjects will follow the...

Summary: This study aims to discover circulating microRNAs (associated with drug doses and levels) that can be used to characterize the overall immune state in pediatric heart transplant patients and predict patients that will go on to develop infection and rejection. MicroRNAs (miRs) are small, non-coding RNA molecules that regulate gene expression and serve as molecular biomarkers found in the circulatio...

Summary: The goal of this study is to evaluate if hypertonic saline solution can prevent or attenuate acute kidney injury after heart transplantation in the early postoperative phase.

Summary: The Mycophenolate Pregnancy Registry is designed as a prospective, observational registry collecting data regarding mycophenolate exposure during pregnancy, and pregnancy outcomes, fetal and infant outcomes after exposure. Early and later term pregnancy outcomes will be solicited at selected gestational time points. Structural and functional birth defects identified in the perinatal period through...

Summary: Conduction system pacing vs biventricular resynchronization therapy in systolic dysfunction and wide QRS: mortality, heart failure hospitalization or cardiac transplant (CONSYST-CRT II trial). Superiority trial that aims to study the composite endpoint consisting of all-cause mortality, cardiac transplant or heart failure hospitalization at 12-month follow-up.

Summary: The aim of the study is to evaluate the impact of early microvascular disease assessed by coronary physiologic indices such as fractional flow reserve (FFR), coronary flow reserve (CFR), index of microvascular resistance (IMR) on future occurrence of cardiac allograft vasculopathy (CAV) in heart transplant recipients.

Summary: We will conduct a two-group randomized controlled trial to examine the eMocha DOT intervention with pediatric HT recipients.In this population, medication nonadherence remains a primary cause of late acute rejection (LAR) episodes, increased number of hospitalizations, graft failure, and patient mortality. Herein, we propose an innovative approach to promote medication adherence and improve patien...

Summary: Transthyretin cardiac amyloidosis (ATTR-CA) is a relentlessly progressive disease that can progress to end stage heart failure, at which point recently approved transthyretin production silencing or structure stabilizing therapies provide no clinical benefit. For well-selected individuals, heart transplantation is an excellent therapeutic option to improve survival. Historically, concomitant liver...

Summary: This is a phase 2, prospective, multi-center, open-label clinical trial. Sixty-six (66) primary heart transplant recipients will be randomized (1:2) to receive either standard-of-care, tacrolimus-based immunosuppression, or a belatacept-based regimen with gradual tacrolimus withdrawal over 9-months post-transplant. Both study arms will receive CellCept® (mycophenolate mofetil- MMF) or Myfortic® (m...
