A coronary artery fistula (CAF) is defined as a direct connection between with right heart chambers including the atrium, ventricle, sinus, superior vena cava, or pulmonary arteries. Elective closure of by surgery percutaneous transcatheter technique generally accepted in presence symptoms. We report case successful device fistula, originating from circumflex and draining into sinus.

We report a rare case of atrial tachycardia originating from the non-coronary aortic sinus. After failed radiofrequency (RF) energy applications at right His-bundle region, the complete elimination of atrial tachycardia was achieved with an RF energy application in the non-coronary aortic sinus. With the review of other papers, this report emphasizes the importance of mapping in the non-coronar...

a double left anterior descending (lad) coronary artery emerging from the left and right coronary arteries is classified among rare coronary anomalies. we herein report a 73-year-old man presenting with acute coronary syndrome (posterolateral myocardial infarction). he was admitted with typical chest pain, and due to his progressive ischemic changes on electrocardiography (ecg) and elevated car...

OBJECTIVE To present a technical proposal based on the experience of 130 implantations using a simplified technique for coronary sinus catheterization, based on the atrial component of the intracavitary electrogram and radiological anatomy. METHODS From October, 2001 to October, 2004, 130 biventricular pacemaker implantations were performed, using radiological anatomy and observation of the i...

Coronary aneurysms are typically seen in association with Kawasaki disease and only in rare instances, they are reported to be congenital or idiopathic. Here we report a case of a five year old boy who was found to have an idiopathic right coronary artery aneurysm. He presented with complaints of recurrent respiratory tract infections. His examination and investigations did not reveal any of th...

Described by many authors, valves refer to the coronary sinus. The best known among them are Thebesius and Vieussen valves. Information about valves in the lumen of the coronary sinus, though, is rarely found in anatomic literature. Frequency of occurrence of valves in the lumen of the coronary sinus and the degree of their formation was chartered in this paper. 150 adult human hearts of both s...

Ruptured valsalva sinus aneurysm to pericardium is a rare condition. Here, we described a case presented with tamponade. Initially, hemopericardium was partially drained and then, imaging evaluations were done. Transesophageal echocardiography showed limited dissection of aortic sinus and CT angiography of the ascending aorta showed deformed dilated right coronary sinus. Besides, surgery showed...

Fig. 1. (A) CT scan image. CT scan shows giant non-coronary sinus of Valsalva aneurysm with neighbouring structures. Arrows indicate closed aortic valves. Ao: aorta, NC-SVA: non-coronary sinus of Valsalva aneurysm, LV: left ventricle, PA: pulmonary artery. (B) TEE image. Trans-oesophageal echocardiography shows aortic cusps level image of sinus of Valsalva aneurysm. *Arrows show aortic cusps, *...

KADISH, A.H., ET AL.: An Experimental Study of Transvenous Defibrillation Using a Coronary Sinus Catheter. The efficacy of a transvenous defibrillating system, utilizing bipolar right ventricular and coronary sinus catheters was evaluated in 14 normal mongrel'dogs. Tivo groups of seven animals each were studied^ During all shocks, the right ventricular apex electrode sensed as the anode. In bot...
