The study is a retrospective study and is descriptive in nature. In this study, the investigators aimed to emphasize the importance of anesthesia management by cardiac risk assessment of patients undergoing epicardial ablation under general anesthesia and analysis of complications that developed during the procedure.

The study is retrospective observational and data were collected by examining the files of all epicardial ablation patients received in the angiography unit starting from 30.10.2020 until 30.10.2022 after ethics committee approval is obtained. Baseline characteristic features of the patients Sex, Age, (years, BMI (kg/m2) Hypertension, Coronary artery disease, COPD (Chronic obstructive pulmonary disease), CKD (Chronic kidney disease) Electrical storm, and ventricular tachycardia etiology, Ischemic cardiomyopathy, Dilated cardiomyopathy, the presence of ARVC (Arrhythmogenic Right Ventricular Cardiomyopathy), Hypertrophic cardiomyopathy will be recorded. NHYA classification will be examined in two groups as NHYA I or II and NHYA III or IV, also estimated glomerular filtration rate, left ventricular ejection fraction, PAAINESD (acute hemodynamic decompensation risk assessment score), iVT score (Risk of VT recurrence) Score information will be recorded. Ventricular tachycardia focus locations, dopamine, dobutamine, norepinephrine infusion requirement during the procedure, arrest development during the procedure, fluoroscopy time and ablation times will be recorded. In the follow-up of the patients after the procedure Causes of death, decompensated heart failure, transient ischemic attack, development of acute renal failure, and recurrence of ventricular tachycardia will be recorded. PAAINESD score (acute hemodynamic decompensation risk assessment score) will be recorded. The PAAINESD Score, developed to estimate the risk of periprocedural hemodynamic decompensation, has values ranging from 0 to 35 points (or 0 to 31 \[PAINESD\] when the modifiable intraprocedural variable general anesthesia is excluded). duration of the procedure, the need for inotropes during the procedure, whether the patient needed mechanical ventilation after the procedure, and the success rates after the procedure will be recorded. PAINESD Pulmonary disease (chronic obstructive pulmonary disease) 5 Age \>60 years 3 Anaesthesia (general) 4 Ischaemic cardiomyopathy 6 NYHA class III or IV 6 Ejection fraction \<25 % 3 Storm (VT). 5 Diabetes 3 Data will be analyzed in three separate categories, the characteristics of the patients before the procedure, during the procedure and after the procedure. Descriptive tables and percentages of parameters will be created by statistical analysis.
