Successful left-sided accessory pathway ablation without reference catheter in patient with atresia of coronary sinus and thin persistent left superior vena cava
نویسندگان
چکیده
We report a case of atrioventricular reentrant tachycardia (AVRT) with ostial atresia of the coronary sinus (CS). Without the anatomic angiography, radiofrequency (RF) energy was applied at the mitral valve annulus and the bypass tract was eliminated. After the therapy procedure, by CS angiography, we knew the persistent left superior vena cava (PLSVC), and the coronary sinus was connected with vena cava superior, very thin in a diameter. The therapy procedure was successful. The patient has remained completely symptom free.

Introduction Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval, wide QRS complex, and paroxysmal supraventricular tachycardia. An accessory atrioventricular connection is known to be the underlying mechanism of this syndrome. Accessory pathways (APs) are mainly located along the tricuspid or mitral annulus, accounting for 10%– 20% and 50%–60% of cases, respectively. M...

Coronary sinus anomalies are rare congenital defects which are usually coexistent with a persistent left superior vena cava and may be associated with cardiac arrhythmias. We report an unroofed coronary sinus without persistent left superior vena cava diagnosed during a catheter ablation procedure for Wolff-Parkinson-White syndrome. Diagnostic and therapeutic options and outcomes are discussed....

Persistent left superior vena cava is a congenital vascular anomaly, which is possibly arrhythmogenic and thrombogenic, rarely complicated with coronary sinus atresia. We treated a 42-year-old male with Hodgkin's lymphoma requiring central venous catheter placement for intensive chemotherapy. Persistent left superior vena cava was revealed after the insertion of the central venous catheter by t...

Total upper body drainage via left superior vena cava into coronary sinus (i.e. absent right superior vena cava) is a rare anomaly and distorts the anatomy of coronary sinus and triangle of Koch. Herewith we are reporting the first report of ablation in a patient with superior vena cava draining into coronary sinus totally. This patient with atrioventricular nodal re-entrant tachycardia, baseli...
