Use of a handheld epicardial ultrasonic Doppler flow detector to locate an intramyocardial coronary artery encased in inflamed neoplastic pericardium.

A 44-year-old man had severe stenosis of the left main coronary artery. The middle portion of the left anterior descending coronary artery was in an intramyocardial location. The pericardium, ascending aorta, epicardium, and coronary arteries were encased by a metastatic, poorly differentiated papillary adenocarcinoma. The left anterior descending artery was located with the aid of a handheld epicardial ultrasonic Doppler flow detector, and grafted with the left internal thoracic artery on a beating heart. Subsequently, the patient underwent 10 cycles of chemotherapy More than 22 months later, he was asymptomatic and in remission from neoplastic disease.

Diaphragmatic defect with peritoneopericardial communication.

An 81-year-old man had a congenital defect of the central tendon of the diaphragm, including a peritoneopericardial communication with herniation of the omentum to the pericardial sac in front of the heart. In addition, he had a critically stenosed congenital bicuspid aortic valve and severe coronary artery disease. The patient underwent reduction of the herniated omentum into the abdominal cavity, coronary artery bypass grafting, aortic valve replacement, and closure of the peritoneopericardial communication with a synthetic patch. Three years later, the patient was doing well, with a normally functioning pericardial valve in the aortic position and no sign of omentum around the heart.

Congenital bicuspid aortic valve disease with an aneurysm of the ascending aorta in adults: vertical reduction aortoplasty with distal external synthetic wrapping.

In three adult patients with diseased congenital bicuspid aortic valves and aneurysms of the ascending aorta, we performed aortic valve replacements, and combined a proximal and middle vertical reduction aortoplasty with a distal external synthetic wrapping. During a mean follow-up of 23.3 months there is no evidence of compression of the innominate artery by the distal external synthetic wrap, and no redilatation of the ascending aorta.

Right-sided double aortic arch in an adult.

A 27-year-old woman complained of a severe stridor caused by a right-sided double aortic arch with a right-sided descending thoracic aorta. A smaller left-sided aortic arch had an atretic segment located between the left common carotid artery and an aortic diverticulum from which the left subclavian artery originated. Through a left fourth thoracotomy, the atretic segment, which caused a compression of the trachea and esophagus, was ligated and divided. The ligamentum arteriosum could not be identified on that side. After the operation she was completely relieved of her symptoms.

Congenital bicuspid aortic valve and an aneurysm of the ascending aorta.

BACKGROUND: A congenital bicuspid aortic valve (BAV) in adults is known to be associated with aortopathy, specifically with aneurysms of the ascending aorta (AA). MATERIALS AND METHODS: Ten (16.7%) patients with congenital BAV had an aneurysm of the AA. Aortic valve replacement was performed in 58 patients, repair in two. Aneurysms were repaired by a vertical reduction (tailoring) aortoplasty (VRA) with or without external synthetic grafting (wrapping, wrap) in nine patients, replaced in one. RESULTS: There were no operative deaths. One patient died 87 months after the operation due to a noncardiac cause. Fifty-four patients are alive and well, without the evidence of recurrence of an aneurysm. CONCLUSIONS: A VRA with or without external synthetic wrapping appears to be a satisfactory alternative to replacement procedures for the AA aneurysm in older patients with BAV, and those with comorbid conditions.
