RESUMEN
Cardiac allograft vasculopathy (CAV) is frequently observed after heart transplant (HT), and represents one of the main causes of chronic rejection, graft loss, and death. While the role of percutaneous coronary intervention (PCI) is well established in the management of CAV in cases of nonocclusive stenoses, the outcomes and technical aspects of this procedure in chronic total occlusions (CTOs) are unknown. We describe our experience with three cases in which CTO PCI was indicated to treat CAV in HT recipients, and we discuss the peculiarities and therapeutic approach to this challenging patient population. In particular, all patients were asymptomatic for angina, and CTO PCI was indicated to promote recovery of left ventricular function, extend graft survival, and/or protect from future ischemic events. CTO PCI was performed using hybrid techniques and was successful in all three cases. Intravascular imaging was used in all cases to maximize the durability of the procedure.

Fear of acquiring severe acute respiratory syndrome coronavirus-2 infection is a major contributor to underutilization of the health care system during the current pandemic. In this report, we describe 4 cases of unexpected deaths that occurred within a short time period in patients with adult congenital heart disease without warning symptoms.
