What are the predictors of hemodynamic deterioration following radiofrequency ablation of the atrioventricular conduction system in patients with drug refractory atrial fibrillation?
Hemodynamic deterioration with progression of mitral regurgitation occurs in up to 7.4% of patients after AV node ablation, particularly in those with high baseline left ventricular end-diastolic diameters.
Vanderheyden et al. (1997) conducted an observational in Drug refractory atrial fibrillation (n=108). Radiofrequency ablation of the atrioventricular conduction system vs. Patients without hemodynamic deterioration was evaluated on Hemodynamic deterioration with worsening mitral regurgitation. Radiofrequency ablation of the atrioventricular conduction system caused hemodynamic deterioration and worsening mitral regurgitation in 7.4% of patients, especially those with high baseline LVEDD.
