Impact of significant paravalvular leaks after transcatheter aortic valve implantation on anaemia and mortality.

Objective: The aim of this work is to assess the relationship between significant paravalvular leak (SPL) after transcatheter aortic valve implantation (TAVI) on anaemia and their impact on prognosis.

Methods: Observational analytic study developed at two university hospitals, including all consecutive patients who underwent TAVI during a 10-year period (2009 to 2018). A logistic regression model was created to determine independent predictors of anaemia at 3 months.

Prognostic impact of the SYNTAX score II in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention: analysis of a four-year all-comers registry.

Aims: This study aimed to investigate the prognostic impact of the SYNTAX score II (SS-II) on ST-segment elevation myocardial infarction (STEMI) patients undergoing a primary percutaneous coronary intervention (pPCI).

Methods And Results: This retrospective cohort study included 1,689 patients with STEMI who underwent pPCI between January 2008 and December 2016. The patients were categorised into three groups based on SS-II tertiles (SS-II low tertile <24 [n=585], SS-II intermediate tertile ≥24 and ≤34 [n=567], and SS-II high tertile >34 [n=537]).
