The introduction of transcatheter aortic valve implantation (TAVI) has generated a renewed interest in the treatment of high-risk patients with severe aortic stenosis. This study describes the indications and long-term outcome of balloon aortic valvuloplasty (BAV) in recent years. ⋯ The number of BAV is increasing, mainly due to increased referral of high-risk patients and to the emerging indication of bridge for TAVI. In this complex population, BAV is relatively safe but two-year survival remains poor, and more effective and definitive treatments should be pursued in a timely fashion.

Residual paravalvular aortic regurgitation (PAR) after transcatheter aortic valve implantation (TAVI) is common. We therefore evaluated incidence, determinants and outcome of PAR after TAVI. ⋯ In patients undergoing TAVI, moderate and moderate-to-severe PAR was observed in 14.4% and associated with increased cardiovascular mortality. A pressure gradient ∆PDAP-LVEDP≤18 mmHg carries adverse prognosis and requires further intervention.

The aim of this prospective multinational registry is to assess and identify predictors of in-hospital outcome and complications of contemporary TAVI practice. ⋯ Increased operator experience and the refinement of valve types and delivery catheters may explain the lower rate of mortality, stroke and vascular complications than in historical studies and registries.
