The Prognostic Utility of Invasive Right Heart Catheterization in Patients Prior to Transcatheter Aortic Valve Replacement

CONCLUSIONS: Preprocedural invasive RHC provides useful prognostic information. A comprehensive invasive hemodynamic assessment should be considered for risk stratification in patients undergoing TAVR.PMID:34866047

AbstractBalloon aortic valvuloplasty (BAV) was developed as a technique to treat aortic stenosis (AS) and is associated with significant improvements in aortic valve area and trans-aortic valve gradient in the early and immediate periods after the procedure. BAV is commonly performed using a trans-femoral retrograde approach; however, trans-femoral access is associated with frequent access-site bleeding. Among 146 patients with symptomatic severe AS who were treated with BAV in our institution, 123 patients received BAV treatment via a trans-radial approach using a 7-Fr Glidesheath. The balloon size was 16 –20 m...

Nature Reviews Cardiology, Published online: 24 November 2021; doi:10.1038/s41569-021-00656-8Early surgical aortic valve replacement in asymptomatic patients with severe aortic stenosis reduces the risk of all-cause death, acute myocardial infarction, stroke or unplanned hospitalization for heart failure compared with conservative care and surgical aortic valve replacement only after symptom onset, according to findings from the AVATAR trial.

Conclusions: In asymptomatic patients with severe AS, early surgery reduced a primary composite of all-cause death, acute myocardial infarction, stroke or unplanned hospitalization for heart failure compared with conservative treatment. This randomized trial provides preliminary support for early SAVR once AS becomes severe, regardless of symptoms.PMID:34779220 | DOI:10.1161/CIRCULATIONAHA.121.057639

Transcatheter aortic valve implantation (TAVI) is at least as safe and effective as surgical aortic valve replacement (SAVR) in patients with severe symptomatic aortic stenosis for the endpoints of all-cause mortality, stroke and heart failure hospitalizations across the spectrum of surgical risk1,2. Despite iterative advances in technology and refinements in procedural technique, conduction disturbances are not infrequent and occur more commonly after TAVI than after surgery. In the most recent low-risk randomized trials2,3 comparing TAVI to SAVR, the rates of permanent pacemaker implantation (PPI) were 6.6% with the ball...

AbstractThe purpose of this study was to explore the utility of echocardiography and the EuroSCORE II in stratifying patients with low-gradient severe aortic stenosis (LG SAS) and preserved left ventricular ejection fraction (LVEF  ≥ 50%) with or without aortic valve intervention (AVI). The study included 323 patients with LG SAS (aortic valve area ≤ 1.0 cm2 and mean pressure gradient

The aim of this study was to compare clinical outcomes following transcatheter aortic valve implantation (TAVI) between the patients primarily diagnosed by heart murmur and those diagnosed by other reasons. We retrospectively included 258 patients who underwent TAVI in our medical center, and divided those into the murmur group ...
