RIght VErsus Left Apical transvenous pacing for bradycardia: Results of the RIVELA randomized study.

ABSTRACT: AIMS:To compare cardiac function when pacing from the right or left ventricular apex in patients with preserved left ventricular systolic function, at 1-year follow-up. METHODS:Prospective, multicentre centre randomizing conventional right ventricular apical (RVA) versus left ventricular apical (LVA) pacing using a coronary sinus lead in patients requiring ventricular pacing for bradycardia. Follow-up was performed using 3D-echocardiography at 6 and 12 months. RESULTS:A total of 36 patients (age 75.4 ± 8.7 years, 21 males) were enrolled (17 patients in the RVA group and 19 patients in the LVA group). A right ventricular lead was implanted in 8 patients in the LVA group, mainly because of high capture thresholds. There were no differences in the primary endpoint of LVEF at 1 year (60.4 ± 7.
