Regional left ventricular function after transapical vs. transfemoral transcatheter aortic valve implantation analysed by cardiac magnetic resonance feature tracking.
This study analysed the impact of transapical (TA) vs. transfemoral (TF) access site transcatheter aortic valve implantation (TAVI) on post-procedural regional left ventricular (LV) function using cardiac magnetic resonance (CMR) feature tracking (FT). ⋯ Apical LV function abnormalities can be detected at 3-month follow-up in all TA-TAVI patients using CMR-FT. TA-TAVI results in significant impairment of apical LV function compared with TF-TAVI.

Conventional surgery and transcatheter closure via surgical transapical approach for paravalvular leak repair in high-risk patients: results from a single-centre experience.
Paravalvular leaks (PVL) occur in up to 17% of all surgically implanted prosthetic valves. Re-operation is associated with high morbidity and mortality. Transcatheter closure via a surgical transapical approach (TAp) is an emerging alternative for selected high-risk patients with PVL. The aim of this study was to compare the in-hospital outcomes of patients who underwent surgery and TA-closure for PVL in our single-centre experience. ⋯ A transcatheter closure via a surgical TAp approach appears to be a safe and effective therapeutic option in selected high-risk patients with PVL and is associated with a lower hospital mortality than surgical treatment, in spite of higher predicted risk. Long-term survival remains suboptimal in these challenging patients.
