Emergent Ablation for Ventricular Tachycardia: Predictors of Prolonged Hospitalization and Mortality
Authors' conclusion
Patients undergoing emergent VT ablation are at high risk for prolonged hospital stay, which is predicted by NYHA functional class III or higher and a prior failed ablation. Early VT recurrences and worsening heart failure contribute to prolonged hospitalization and a high 30-day mortality.
