Isolated congenital aneurysm of the left atrium with intact pericardium is a rate anomaly, which usually presents with arrhythmia, cerebral embolism or abnormalities on routine chest X-ray. Surgery is indicated in most cases to eliminate a potential source of systemic emboli and arrhythmias. A 42-year-old woman having cervical cancer, she was suspected of having a left atrial aneurysm on review of chest X-ray and confirmed by echocardiography and cardiac catheterization. Surgical resection of Left atrial aneurysm was achieved without complication using median sternotomy with cardiopulmonary bypass. The postoperative course was uneventful.

A left atrial appendage aneurysm is a very rare medical condition which can develop by an inflammatory reaction or a degenerative change. If there is no accompanying anomaly, a left atrial appendage is considered a congenital disease. The majority of left atrial appendage aneurysms are detected incidentally because they usually do not cause any symptoms. Surgery is indicated, even for asymptomatic patients, because of the risk of life-threatening complications, such as atrial fibrillation, supraventricular tachycardia, systemic embolization, and cardiac arrest. Left atrial appendage aneurysms are usually treated by a median sternotomy with extracorporeal circulation, especially if the aneurysm has a broad base or contains a thrombus, but can treated by thoracotomy without extracorporeal circulation. We report a case of a successfully treated left atrial appendage aneurysm that was misdiagnosed as a partial pericardial defect without extracorporeal circulation in a 13-year old child.

Left atrial appendage aneurysm (LAAA) is a rare heart anomaly caused by congenital dysplasia of the pectinate muscle or by an acquired pathological condition of the mitral valve or cardiac muscle. It is often incidentally discovered during chest CT or echocardiography as an abnormal dilatation of the LAA. LAAA is associated with life-threatening complications and most patients require surgical treatment. Therefore, it is important to evaluate associated complications as well as precise diagnoses. This report presents the case of a surgically confirmed LAAA in a 53-year-old female. We also discuss the pathophysiology of LAAA and significant findings related to mortality that can be detected on CT and MRI.

Congenital intrapericardial left atrial appendage aneurysms (LAAA) are very rare. Most cases are asymptomatic and this malady is generally incidentally diagnosed in older patients. LAAAs are usually accompanied with supraventricular arrhythmias and life-threatening systemic embolism. Complete surgical correction is recommended immediately after the diagnosis to prevent significant complications, and even for the asymptomatic patients. We report here on the case of a 45-year-old man who presented with cerebral embolism due to LAAA. The patient was successfully treated with a resection of the aneurysm.

Aneurysm of the sinus of Valsalva on mostly congenital disease that develops more frequently in Orientals, is very low in incidence. In most cases, aneurysm of the sinus of Valsalva extends to intracardiac and results in ruptures into the right ventricle or atrium. The likelihood of extracardiac aneurysm of the sinus of Valsalva is very low. Cases of extracardiac aneurysm are usually accompanied by aortic regurgitation and can cause right ventricle outflow tract obstruction, myocardial ischemia, and myocardial infarction due to compression by aneurysm. Since the aneurysm can rupture in the intrapericardium and cause cardiogenic shock or sudden death, definite diagnosis and management are important. If confirmed, it is preferable operform a surgical correction. We report here, with a literature review, a case where myocardial ischemia and aortic egurgitation caused by aneurysm developed in the left coronary and noncoronary sinus, and were surgically corrected with satisfactory esults.

Background: Although there have been few reports about minimal skin incision for the repair of congenital heart lesions, minimizing an unsightly scar is a particularly important factor in growing children. We have adopted a technique that permits standard full sternotomy, conventional open chest cardiopulmonary bypass, aortic cross-clamping, left atrial vent, and antegrade cardioplegia with minimal surgical scar. Material and Method: With minimal skin incision and full sternotomy, 40 patients with congenital heart disease underwent open heart surgery from April 1997 through September 1997. Defects repaired included 30 ventricular septal defects, 4 atrial septal defects, and 1 sinus Valsalva aneurysm in 35 children(M:F=17: 18), and 3 Atrial septal defects, 1 ventricular septal defect, and 1 partial atrioventricular septal defect in 5 adults(M:F=1:4). Midline skin incision was performed from the second intercostal space to 1 or 2 cm above the xiphoid process. For full sternotomy, we used the ordinary sternal saw in sternal body, and a special saw in manubrium under the skin flap. During sternal retraction, surgical field was obtained by using two retractors in a crossed direction. Result: The proportion of the skin incision length to the sternal length was 63.1${\pm}$3.9%(5.2∼11cm, mean 7.3cm) in children, and 55.0${\pm}$3.5%(10∼13.5cm, mean 12cm) in adults. In every case, the aortic and venous cannulations could be done through the sternal incision without additional femoral cannulation. There was no hospital death, wound infection, skin necrosis, hematoma formation, or bleeding complication. Conclusion: We conclude that minimal skin incision with full sternotomy can be a safe and effective alternative method for the repair of congenital heart diseases in children and adults.
