Abstract

Objective. This study aims to determine efficacy and safety of rapid left ventricular pacing (RLVP) during balloon aortic valvuloplasty and effect on development of postprocedural aortic insufficiency (AI) in children. Design. This is a retrospective comparison of 56 children (mean age 18.3 month; 1 day-15 years of age) who underwent valvuloplasty by using RLVP with standard method (without pacing) during same time period (74 children; mean age 12.6 month; 1 day-18 years of age). Results. The systolic valvular gradient decreased from a mean 67 +/- 20.4 mm Hg (26-120 mm Hg) before the procedure to a mean 27.6 +/- 17.8 mm Hg (0-120 mm Hg) after the procedure. Procedure failed in two of the patients (3.6%) who received the RLVP; only two patients developed severe AI. Among those patients who underwent the standard method procedure failed in 6 patients (8.3%), whereas severe AI was seen in 15 (20.2%). RLVP decreased the incidence of postprocedure severe AI significantly (P < .01) but it had no effect on the gradient reduction of the procedure (P > .05). RLVP did not change the procedure duration, but decreased the duration of fluoroscopy significantly (P < .01). Conclusion. RLVP can be used effectively and safely for pacing during balloon aortic valvuloplasty procedures in all age groups; it decreases procedural failure rate, eases the procedure and prevents the development of AI through the stabilization of the balloon.
