Rupture of right coronary artery aneurysm into the right atrium.

A 63-year-old man presented with acute congestive heart failure and was found to have a continuous murmur. Two years earlier, he had an inferior myocardial infarct, when no murmurs were heard. Angiography showed a right coronary artery aneurysm communicating with the right atrium. The distal vessel was occluded. The aneurysm was resected and the patient remains well. It is proposed that this was a congenital aneurysm which led firstly to the myocardial infarct and finally ruptured into the right atrium.     

Rupture of an aneurysm of the noncoronary sinus of Valsalva into the right atrium

A 32-year-old woman presented to the emergency department afterthe sudden onset of palpitations, dyspnoea and left-sided tinnitus.Echocardiography revealed a ruptured aneurysm of the noncoronarysinus of Valsalva into the right atrium. Due to deteriorationof right heart failure with rapidly progressive decline of systemicblood pressure, the patient underwent immediate surgery witha patch repair of the ruptured aneurysm. A few days later, thepatient was discharged home in good condition.     

Rupture of a congenital aneurysm of the non-coronary sinus of Valsalva into the right atrium.

We present the case of a patient evaluated for a continuous murmur, in which a ruptured congenital sinus of Valsalva aneurysm with fistulization to the right atrium was demonstrated by echocardiography. The authors review the relevant clinical features of this entity.     

Coronary artery fistula following rupture of aneurysm of the sinus node artery into the right atrium

A case of coronary artery fistula secondary to rupture of a coronary artery aneurysm is reported. The association of these 2 conditions is rare. Successful surgical treatment was achieved by use of a Dacron patch to close the fistula.     

Mycotic aneurysm of the right coronary artery

Mycotic embolism in patients with infective endocarditis is not uncommon, however, mycotic aneurysm of a coronary artery is very rare. We report the case of a 62-year-old woman with mitral valve endocarditis complicated by mycotic aneurysm of the right coronary artery. Mitral valve replacement and resection of the mycotic aneurysm with coronary artery bypass were performed.     

Giant aneurysm of the right coronary artery

INTRODUCTION: Giant coronary aneurysms are rare and often confused with cardiac tumours. OBSERVATION: We report a new case of this type of aneurysm occurring on the right coronary artery revealed by a cardiac congestion. COMMENTS: These aneurysms can be due to inflammatory diseases or dysplasia. But in these pseudotumoral forms, atherosclerosis is the main aetiology. The diagnosis and treatment require surgery and histological examination.     

Left-circumflex coronary artery to right atrium fistula with saccular aneurysm and its endovascular treatment

The combination of coronary artery aneurysm and coronary artery fistula is infrequent. A saccular aneurysm of a branch of the left-circumflex coronary artery associated with multiple fistulae to the right atrium was observed on a coronary angiogram performed in a 47-year-old female. Multidetector computed tomography coronary angiography detailed the anatomy of the abnormal coronary artery. An embolization with a microcoil was performed and the aneurysm sac was excluded.     

Left main coronary trunk connecting into right atrium with an aneurysmal coronary artery fistula

Congenital coronary artery fistula (CAF) is an infrequent vascular anomaly that establishes a direct link between an epicardial coronary artery and a cardiac chamber, major vessels, or other vascular structures. In this case there was an aneurysmal-CAF between a left main trunk and the right atrium, which was initially diagnosed as a Kawasaki disease by transthoracic echocardiography and subsequently confirmed by coronary angiography and multi-slice CT angiography. A multi-slice CT angiography might well become the modality of choice for the characterization of these rare congenital anomalies.     

Diverticular aneurysm of the right atrium

A case of right atrium aneurysm (diverticulum) detected in an asymptomatic 61-year-old woman is described. Diagnosis was made according to echocardiographic and echocontrastographic findings and was confirmed by both angiographic data and surgical pathology. The rarity of this finding and the possibility of a correct non-invasive assessment can be considered the two most peculiar features of this case.
