Incidence and Predictors of ICD Therapy in Patients With Arrhythmogenic Right Ventricular Dysplasia/ Cardiomyopathy (ARVC) Undergoing ICD Implantation for Primary Prevention
Eighty-four patients with definite or probable ARVC underwent ICD implantation for primary prevention. After a follow-up of 4.7 ± 3.4 years, appropriate ICD therapy was delivered in 40 patients (48%). Predictors of such an intervention were proband status (p < 0.001), inducibility at electrophysiologic study (p = 0.005), presence of nonsustained ventricular tachycardia (p < 0.001), and Holter premature ventricular complex count >1,000/24 h (p = 0.024). In multivariate analysis, inducibility at electrophysiologic study and nonsustained ventricular tachycardia remained significant predictors. The number of these risk factors correlates with the incidence of ICD activation with the 5-year survival free of appropriate ICD therapy for patients with 1, 2, 3, and 4 risk factors being 100%, 83%, 21%, and 15%, respectively (Bhonsale A et al, J Am Coll Cardiol 2011; 58:1485-1496).
Exclusion of the Left Atrial Appendage with a Novel Device: Early Results of a Multicenter Trial
Seventy patients with atrial fibrillation or a CHADS2 score greater than 2 undergoing elective cardiac surgery were eligible for concomitant AtriClip device (35, 40, 45, and 50 mm) insertion. Safety was assessed at 30 days, and efficacy of left atrial appendage exclusion was assessed at operation (by transesophageal echocardiography) and at 3-month follow-up (by computed tomography angiography or transesophageal echocardiography). Intraprocedural success reached 95.7% (67 of 70 patients). Although significant adverse events occurred in 34 of 70 patients (48.6%), none was related to the device and there was no perioperative mortality. At 3-month follow-up, 98.4% of the patients had successful left atrial appendage exclusion by computed tomography angiography or transesophageal echocardiography imaging (Ailawadi G et al, J Thorac Cardiovasc Surg 2011; 142:1002-1009)...
