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.     

False aneurysm of the right atrium.

A false aneurysm of the right atrium is described. The false aneurysm appeared after open-heart surgery and was probably related to loosening of a right atrial suture. Because of the low pressure in the right atrium, the danger of rupture seemed to be low, and conservative therapy was chosen.     

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.     

Coronary artery aneurysm with a fistulous connection to the right atrium mimicking a sinus of Valsalva aneurysm

Coronary artery aneurysms are uncommon and may be complicated by rupture, thromboembolic phenomenon, and more rarely fistulation into one of the cardiac chambers. This case report highlights the difficulty in making a preoperative diagnosis of a coronary artery aneurysm that has fistulated into the right atrium, and lists possible differential diagnoses.     

A saphenous vein graft aneurysm with fistula development to the right atrium: Surgical management of a rare bypass graft complication

A patient presented late following coronary artery bypass surgery with recurrent angina. Investigations revealed a saphenous vein graft aneurysm, which subsequently formed a fistula with the right atrium. This was managed by surgical excision and repair followed by regraft of the run-off territory. Intraoperatively, the left internal mammary artery, a patent graft to the left anterior descending artery, was isolated from the circulation during aortic cross-clamping by preoperative placement of a percutaneous balloon catheter within this graft. Surgery was successful and the patient was discharged symptom-free one week later.     

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.     

Left sinus of Valsalva aneurysm with rupture into the right atrium.

Herein, we present the echocardiographic diagnosis of a case of left sinus of Valsalva aneurysm with rupture into the right atrium.     

Post-infarction communication between a left ventricular aneurysm and the right atrium.

A 70-year-old patient presented with ventricular tachycardia and left ventricular failure. He was found to have a communication between a posterior left ventricular aneurysm and the right atrium. The causal myocardial infarction had been silent. This defect was satisfactorily closed at operation from which he made an uneventful recovery. This is the first report of a left ventricular-right atrial communication developing in association with ischaemic heart disease and highlights the role of transoesophageal echocardiography in the diagnosis and surgical management of such a condition.     

Coronary aneurysm with rupture into the right atrium (author's transl)]

A case of a double aneurysm of the left circumflex coronary artery with rupture into the right atrium is described. Additionally, the clinical symptoms of coronary aneurysms and the possible complications are discussed.     

Percutaneous removal of a broken central venous catheter from the right atrium

We report a case of a 32 year-old woman in whom catheter was inserted into a jugular internal vein in order to chronically administer antibiotics intravenously. For the next four years the introducer was kept in place. Due to a persistent cough, the chest X-ray was performed, demonstrating the broken introducer. Since a surgical removal did not succeed, a percutaneous procedure via femoral vein was performed successfully. Our case report draws special attention to the necessity of a regular check-up of patients with intravascular introducers.     

Transesophageal echocardiographic diagnosis of a ruptured sinus of valsalva aneurysm with right atrium fistula

Congenital aneurysms of the sinus of Valsalva are relatively rare, tending to be most frequent in adults. Untreated, there is a substantial risk of complication due to bacterial endocarditis and, if rupture occurs, rapid and progressive cardiac insufficiency is fatal at short term. We report the case of a 53-year-old male with a ruptured right sinus of Valsalva aneurysm, resulting in an anomalous right atrium fistula. Symptoms presented, clinical diagnosis and, above all, transesophageal echocardiography were crucial in the final diagnosis leading to an early and satisfactory surgical intervention. Catheterization and angiography were not definitive. Echocardiographic data are described and a bibliography of relevant research articles is provided.
