What are the incidence and predictors of acute hemodynamic decompensation during catheter ablation of scar-related ventricular tachycardia?
Acute hemodynamic decompensation complicates 11% of scar-related VT ablations and is predicted by factors such as advanced age, ischemic cardiomyopathy, severe heart failure, and general anesthesia, correlating with increased mortality.
AHD occurs in 11% of patients undergoing radiofrequency catheter ablation of scar-related VT and is associated with increased risk of mortality over follow-up. AHD may be predicted by clinical factors, including advanced age, ischemic cardiomyopathy, more severe heart failure status (New York Heart Association class III/IV, lower ejection fraction), associated comorbidities (diabetes mellitus and chronic obstructive pulmonary disease), presentation with VT storm, and use of general anesthesia.
