Abstract [en]

Introduction: Transcatheter aortic valve implantation (TAVI) is an established procedure to treat severe aortic stenosis (AS). This study investigates the impact of ischemic heart disease (IHD) on survival in patients undergoing TAVI.

Aim: Five-year all-cause mortality stratified according to the presence or absence of IHD.

Methods: Retrospective register study including all patients that underwent a TAVI-procedure 2009 to 2018. Patients were stratified according to the presence or absence of IHD. Our primary end-point was five-year all-cause mortality. Survival was analyzed using Kaplan-Meier curve. Data were acquired through the SWENTRY registry and patient files.

Results: A total of 264 patients were included in the study, with 139 (52.7 %) patients in the IHD group vs 125 (47.3 %) patients in the non-IHD group. Mean follow-up time was 40 ±30 months. At baseline, there was a higher proportion of males, patients with hypertension, peripheral arterial disease, left ventricular ejection fraction <50 % and, a higher EuroSCORE I in the IHD-group. Transfemoral approach was most common in both groups. No differences were noted in respect to peri- and postoperative complications. Five-year all-cause mortality was 17/38 (44.7 %) vs 18/30 (60.0 %), p = 0,232, in the IHD and non-IHD group respectively. Non-adjusted cumulative five-year survival was not significantly different between the groups (Log-Rank, p = 0,056).

Conclusions: In patients with severe AS undergoing TAVI, the five-year all-cause mortality was not statistically different between patients with or without IHD.
