A Successful Case of Percutaneous Transluminal Mitral Commissurotomy in Acute Heart Failure from Exacerbation of Mitral Stenosis Following Transcatheter Aortic Valve Implantation

Toshiaki Yamanaka, Mayuko Imamura, Takefumi Oka, Shunsuke Kubo

Objective: Worsening of mitral stenosis (MS) following transcatheter aortic valve implantation (TAVI) is rare, and the precise effect of percutaneous transluminal mitral commissurotomy (PTMC) on MS progression following TAVI remains unclear. We performed PTMC in patients with acute heart failure attributed to MS exacerbation following TAVI. Case Presentation: An 88-year-old woman presenting with exertional dyspnea was admitted to our facility.

N-Terminal Pro-B-Type Natriuretic Peptide for Predicting Early Left Ventricular Ejection Fraction Recovery after Transcatheter Aortic Valve Implantation: A Preliminary Report

Objective: To examine the relationship between baseline N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and early recovery of the left ventricular ejection fraction (LVEF) after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis (AS).

Prognostic Impact of Peak Tricuspid Regurgitation Velocity in Patients Undergoing Transcatheter Aortic Valve Implantation

Objective: No appropriate guidelines concerning perioperative management of transcatheter aortic valve implantation (TAVI) exist for patients with aortic valve stenosis (AS) and concomitant pulmonary hypertension. Peak tricuspid regurgitation velocity (PTRV) has been estimated to be a non-invasive representation of pulmonary artery pressure.
