Outcomes of Catheter Ablation of Ventricular Tachycardia Based on Etiology in Nonischemic Heart Disease: An International Ventricular Tachycardia Ablation Center Collaborative Study
Researchers determined the effects of ventricular tachycardia ablation in nonischemic cardiomyopathy (NICM) patients. By studying the six most common etiologies of NICM, researchers came to the conclusion that the etiology of NICM is an important factor when predicting ventricular tachycardia recurrence, death, or cardiac transplantation. The paper also indicated that adjustments were performed to the data to account for confounding factors such as age, New York Heart Association functional class, left ventricular ejection fraction, etc. Discussions were held among the student scholars to better understand the logistics of this international study and explore the effects of the confounding variables and other limitations of this study.
