Progression and Prognosis of Paravalvular Regurgitation After Transcatheter Aortic Valve Implantation.

Background: The impact of paravalvular regurgitation (PVR) following transcatheter aortic valve implantation (TAVI) remains uncertain.

Objective: To evaluate the impact of PVR on mortality and hospital readmission one year after TAVI.

Methods: Between January 2009 and June 2015, a total of 251 patients underwent TAVI with three different prostheses at two cardiology centers.

Impact of the Occlusion Duration on the Performance of J-CTO Score in Predicting Failure of Percutaneous Coronary Intervention for Chronic Total Occlusion.

Objectives: The present study examined the association between Multicenter CTO Registry in Japan (J-CTO) score in predicting failure of percutaneous coronary intervention (PCI) correlating with the estimated duration of chronic total occlusion (CTO).

Background: The J-CTO score does not incorporate estimated duration of the occlusion.

Methods: This was an observational retrospective study that involved all consecutive procedures performed at a single tertiary-care cardiology center between January 2009 and December 2014.

Prognostic value of renal function in patients with aortic stenosis treated with transcatheter aortic valve replacement.

Objectives: The objectives of the present study were to analyze the variation of renal function after transcatheter aortic valve replacement (TAVR) focused on acute kidney injury (AKI) and its impact on short- and mid-term mortality.

Background: Changes on renal function after TAVR and their impact on clinical outcomes are incompletely understood until now.

Methods: At two tertiary centers 221 consecutive patients were submitted to TAVR.
