Prognostic impact of coronary lesions and its revascularization in a 5-year follow-up after the TAVI procedure.

Background: Coronary artery disease (CAD) is a common finding in patients undergoing transcatheter aortic valve implantation (TAVI). However, its prognostic significance and its management remains controversial.

Aims: This study sought to determine whether the presence of CAD, its complexity, and angiography-guided percutaneous coronary intervention (PCI) are associated with outcomes after TAVI.

Exercise testing in COVID-19 era: Clinical profile, results and feasibility wearing a facemask.

Background: No data are available about whether Coronavirus disease 2019 (COVID-19) pandemic have led to changes in clinical profiles or results of exercise testing once the usual activity was reassumed, as well as if wearing a facemask has any impact on the tests. The aim of this study is to evaluate differences in the patients referred to exercise stress testing in the context of COVID-19 pandemic and analyse the feasibility and results of these tests wearing a facemask.

Methods: We included all patients referred for an exercise test from 1 June to 30 September 2020 and compared them with the patients attended within the same period in 2019 before and after propensity score matching.
