Resultados de la intervenci�n coronaria percut�nea de oclusiones cr�nicas totales en pacientes con trasplante cardiaco

Abstract

Introduction and objectives: Chronic total coronary occlusion (CTO) of coronary arteries is frequent in heart transplant recipients (HTR). It is usually managed with medical therapy due to the suboptimal results shown by the percutaneous coronary intervention (PCI). Although the PCI of native CTOs is performed in experienced centres, in HTR we do not know PCI results or clinical efficacy. This is the first study ever to actually analyse the PCI-Target Lesion Procedure Success of CTO PCI and its angiographic and clinical follow-up in HTR. In addition, we compared the clinical follow-up of CTO vs non-CTO PCI in HTR. Methods: We retrospectively analysed the baseline characteristics, procedural outcomes and clinical events during the follow-up of HTR with CTO undergoing PCI between January 1, 2006 and December 31, 2016 in 2 centres with an ongoing CTO program. Over the same period, we also compared clinical events during the follow-up of these patients vs PCI on non-CTO stenosis in HTR at one of the centres.
