Left Ventricular Roof Ablation

The left ventricular outflow tract lvot is an important source of ventricular arrhythmias va in patients with and without structural heart disease.

Left ventricular roof ablation.

Objectives this study aimed to characterize the incidence clinical characteristics and electrocardiographic and electrophysiologic features of lva va in the. Sometimes ventricular tachycardia ablation involves treatment inside the heart and outside the heart at the same time. The multidisciplinary team of doctors nurses and healthcare professionals in the sydell and arnold miller family heart vascular ventricular arrhythmia center are dedicated to diagnosing and treating patients with ventricular arrhythmias. Ventricular tachycardia ablation typically takes three to six hours.

It has been suggested that ablation lines along the roof of the la and mitral isthmus may improve clinical outcomes in paf. Based on this data there is a clear need for further study to develop strategies to prevent cerebral emboli with catheter ablation especially left ventricular endocardial ablation dr. Radiofrequency ablation or cryoablation can be used during epicardial ablation. Background the left ventricular apex lva is a well described source of ventricular arrhythmias vas in patients with coronary artery disease cad and history of apical infarction but is a rare source of va in the absence of cad.

Whether transseptal access of the left ventricle may be associated with lower cerebral emboli risk needs to be validated in larger studies he said. 7 9 20 conversely the exclusion of the la posterior wall has no effect on the incidence of af recurrences after circumferential pv ablation in a randomized trial of 120 patients 60 in paf.
