Novel Intravascular Ultrasound Measurements to Assess for Coronary Allograft Vasculopathy in Patients after Orthotopic Heart Transplant

Among patients who undergo orthotopic heart transplant (OHT), intravascular ultrasound (IVUS) detection of coronary allograft vasculopathy (CAV), defined as ≥ 0.5 mm increase in maximal intimal thickness (Δ MIT), is associated with worse outcomes at 5 years. Other IVUS-derived measurements of arterial plaque, while validated in studies of coronary atherosclerosis, have not been well studied

Interactive Maps for UNOS Data Visualization

In the United States, heart allocation is administered by the United Network for Organ Sharing (UNOS). UNOS collects demographics and clinical data for all transplant candidates, donors, and recipients listed since 1995. While the data is available to the public upon requests; it has been used predominately for research rather than clinical decision making, transplant

Myocardial Flow Reserve Using 13N Ammonia PET for Detection of Cardiac Allograft Vasculopathy

Risk stratification and early detection of cardiac allograft vasculopathy (CAV) are essential in heart transplantation patients. CAV presents a diffuse vascular involvement, and has been difficult to noninvasively diagnose by the lack of a sensitive method to detect developing vascular pathology in the allograft. The present study investigates the ability of 13N-ammonia PET for detection

Successful Utilization of Extended Criteria Donor (ECD) Hearts for Transplantation – Results of the OCS™ Heart EXPAND Trial to Evaluate the Effectiveness and Safety of the OCS Heart System to Preserve and Assess ECD Hearts for Transplantation

The OCS Heart EXPAND Trial is a prospective, multi-center trial to evaluate the effectiveness of the OCS™ to resuscitate, preserve and assess donor hearts that may not meet current standard donor heart criteria for transplantation to potentially improve donor heart utilization for transplantation.

Metabolic Alterations in Myocardial Metabolism during Ex Situ Heart Perfusion

Ex situ heart perfusion (ESHP) is a novel method for preservation of the donated heart in a semi-physiologic state and provides the opportunity to evaluate pre-transplant function. Because of the well-described extraordinary metabolic requirements of the heart, efficient metabolic support is critical for optimal preservation of function and viability. Our aim was to determine changes
