Preparatory Balloon Aortic Valvuloplasty During Transcatheter Aortic Valve Implantation for Improved Valve Sizing

Objectives This study sought to evaluate whether supra-aortic angiography during preparatory balloon aortic valvuloplasty (BAV) improves valve sizing. Background Current recommendations for valve size selection are based on annular measurements by transesophageal echocardiography and computed tomogr...

Zusammenfassung:	Objectives This study sought to evaluate whether supra-aortic angiography during preparatory balloon aortic valvuloplasty (BAV) improves valve sizing. Background Current recommendations for valve size selection are based on annular measurements by transesophageal echocardiography and computed tomography, but paravalvular aortic regurgitation (PAR) is a frequent problem. Methods Data of 270 consecutive patients with either conventional sizing (group 1, n = 167) or balloon aortic valvuloplasty–based sizing (group 2, n = 103) were compared. PAR was graded angiographically and quantitatively using several hemodynamic indices. Results PAR was observed in 113 patients of group 1 and 41 patients of group 2 (67.7% vs. 39.8%, p
