Meta-analysis of comparison between self-expandable and balloon-expandable valves for patients having transcatheter aortic valve implantation.

Two different devices, 1 self-expanding and 1 balloon-expandable, have been developed for patients who underwent transcatheter aortic valve implantation with contrasting data about efficacy and safety. Pubmed, Medline, and Google Scholar were systematically searched for studies of these different devices, with data derived from randomized controlled trial or registries with multivariate analysis. All-cause death at 30 days and at follow-up were the primary end points, whereas postprocedural moderate or severe aortic regurgitation (AR), stroke, major vascular complications, bleedings, and pacemaker implantation the secondary ones.

Incidence, predictors, and impact on prognosis of systolic pulmonary artery pressure and its improvement after transcatheter aortic valve implantation: a multicenter registry.

Aims: Elevated values of systolic pulmonary artery pressure (sPAP) represent a common finding in patients with aortic stenosis and severe left ventricular hypertrophy. Prognostic impact of sPAP and its potential improvement after transcatheter aortic valve implantation (TAVI) remains to be determined.

Methods And Results: This is a multicenter retrospective registry in five European institutions.

Inaccuracy of available surgical risk scores to predict outcomes after transcatheter aortic valve replacement.

Introduction: Despite encouraging short-term and mid-term results, transcatheter aortic valve implantation (TAVI) interventions are still burdened from high rates of adverse events, stressing the need for accurate predictive risk instruments. We compared available surgical risk scores to describe unfavorable outcomes after TAVI.

Methods: The Age, Creatinine, and Ejection fraction (ACEF) score, the logistic Euroscore, and the Society of Thoracic Surgeons Mortality score (STS) were appraised for their independent power of prediction and for their accuracy (C-index) to predict 30-day and medium-term mortality, according to the Valve Academic Research Consortium.
