![]() ![]() We present a case report of PVI and Posterior Wall Isolation performed via the left subclavian access. In rare cases of congenital or iatrogenic obstruction of inferior vena cava (IVC), RFA of arrhythmias are performed through a transhepatic approach. These procedures are typically performed via femoral vein approach and all devices are designed to be delivered via inferior access. The success rate is shown to be more than 90% and the recurrence rate was less than 10% when complete block of the isthmus was achieved. Typical Atrial Flutter (AF) is generated by a large, counterclockwise reentry circuit in the right atrium and can be successfully eliminated by RFA of cavotricuspidisthmus (CTI) area which is slowly conducting. ![]() Pulmonary vein isolation (PVI) via catheter ablation via femoral approach is a widely applied technique. In 1996, the Bordeaux group noted that AFib is initiated by rapidly firing triggers located in the pulmonary veins. Besides being often symptomatic due to high ventricular rates, it is responsible for functional limitation and cardiomyopathy induced by tachycardia. Ītrial Fibrillation (AFib) is the most common chronic rhythm disorder encountered in clinical practice. ![]() RFA is recommended as first-line therapy in patients with paroxysmal or persistent AF with minimal structural heart disease. Radiofrequency Ablation (RFA) has become a well-recognized non-pharmacological treatment strategy for many cardiac arrhythmias because of a high success rate and low risk of complications. ![]()
