Transcatheter aortic valvuloplasty assisted by right ventricular pacing

The Impact of Rapid Left Ventricular Pacing during Pediatric Aortic Valvuloplasty on Postprocedural Aortic Insufficiency

“…Rapid ventricular pacing was used first via the right ventricle by placing a transient pacemaker lead into the right ventricle. 4,9 Since escape beats lead to higher stroke volume with adenosine, rapid pacing provides steady, low cardiac output. RLVP has an additional advantage over RV pacing in that there is no requirement for extra intervention of the femoral vein and catheter insertion to the right ventricle.…”

“…Balloon stability is achieved by using adenosine, rapid right and left ventricular pacing . The first ventricular pacing was described by Ing et al via a temporary pacemaker electrode inserted to the right ventricle when balloon stability could not be achieved by standard procedure (without pacing) . Four years later, in 2008, rapid left ventricular pacing (RLVP) was described in our institution by Karagöz et al Here, we report procedural success and the midterm follow‐up results of this method and comparison with the standard procedure.…”

Rapid Ventricular Pacing for Catheter Interventions in Congenital Aortic Stenosis and Coarctation: Effectiveness, Safety, and Rate Titration for Optimal Results

“…Ing et al first described the use of rapid ventricular pacing in 13 patients with 31 inflations showing adequate balloon stability during balloon aortic valvuloplasty 10 . Another pilot study demonstrated 14 patients who had balloon movement without pacing underwent valvuloplasty with rapid pacing.…”

Therapeutic Utilities of Pediatric Cardiac Catheterization

“…Aortic balloon valvuloplasty is a percutaneous procedure, involving the inflation of a balloon at the aortic annulus with intention to rip the commissural fusions and fix the obstruction. Concomitant right ventricular pacing stabilizes the balloon by decreasing left ventricular systolic pressure [ 38 ]. Before the procedure a diagnostic catheterization is necessary to collect useful data (pressure gradient across the valve, annular diameter, coexisting regurgitation).…”
