Wolff-Parkinson-White syndrome with an unroofed coronary sinus without persistent left superior vena cava treated with catheter cryoablation
نویسندگان
چکیده
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. This condition is of relevance to electrophysiologists performing catheter-based procedures, as well as cardiologists implanting coronary sinus pacing leads, who may encounter this anomaly in their practice.

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...

متن کاملOcclusion of persistent left superior vena cava to unroofed coronary sinus using vena cava filter and coils.
A 48 year old female with complex cyanotic heart disease and pulmonary hypertension was partly cyanosed because of a persistent left superior vena cava draining into an unroofed coronary sinus. The left superior vena cava, which measured 22 mm in diameter, was successfully occluded with a Günther Tulip Vena Cava Mreye Filter which acted as a barrier for embolisation coils.

A 48-year-old male with a history of secundum type atrial septal defect (ASD) closure in childhood presented to our outpatient clinic complaining of palpitation for six months. Interestingly, transthoracic and transesophageal echocardiography exams showed an undiagnosed partially unroofed coronary sinus associated with persistent left superior vena cava (LSVC) and Cor triatriatum.

We describe a patient with an asymptomatic complete unroofed coronary sinus (CS) syndrome associated with the CS stenosis in the absence of a persistent left superior vena cava (SVC) as identified on coronary computed tomography angiography. There was a large defect between the CS and the left atrium (i.e. a large left-to-right shunt), but an unusual combination of the absence of a persistent l...
