A. Zivin et al., PREDICTORS OF CROSSOVER TO A LEFT-VENTRICULAR APPROACH FOR ATRIOVENTRICULAR JUNCTION ABLATION, The American journal of cardiology, 80(12), 1997, pp. 1611
In a retrospective analysis of patients referred for atrioventricular
node radiofrequency ablation, male gender and a history of hypertensio
n were found to be predictors of crossover to a left ventricular appro
ach for success. This subgroup of patients may benefit from early cros
sover if initial attempts at right-sided ablation fail.
