Real-time integration of intracardiac echocardiography and 3D electroanatomical mapping to guide catheter ablation of isthmus-dependent atrial flutter in a patient with complete situs inversus and interruption of the inferior vena cava with azygos continuation.

摘要: Atrial tachycardias are relatively common in patients with congenital heart disease. However, complex anomalies involving the and great vessels might compromise results of ablation procedure. This report describes a clinical application new Cartosound™ module as an adjunctive technology to understand mechanism arrhythmia guide successfully anatomy. Isthmus-dependent atrial flutter was diagnosed patient complete situs inversus interruption inferior vena cava azygos continuation. Under these unusual circumstances, Cartosound facilitates interventional navigation within right atrium its adjacent structures minimizes radiation exposure.
