Cerebral aneurysms in atrial myxoma: a delayed, rare manifestation.

Atrial myxomas are the most common primary tumors of the heart. Neurologic involvement usually occurs as a stroke with ischemic episodes. Following excision of cardiac myxomas, delayed neurologic events owing to aneurysms are rare and have not been reported from India. We report an operated case of left atrial myxoma. The patient initially presented with a stroke and 6 months after the surgery, developed multiple intracerebral hemorrhages due to the rupture of fusiform cerebral aneurysms, without recurrence of the cardiac tumor.

Supravalvar aortic stenosis: clinical and hemodynamic profile, and surgical outcome.

BACKGROUND: Supravalvar aortic stenosis is the rarest of left ventricular outflow obstructions. Data on this rare entity from India are scarce. METHODS AND RESULTS: We retrospectively analyzed the data of 15 patients (13 males, mean age 15.5+/-10.18 years) with a diagnosis of supravalvar aortic stenosis confirmed by cardiac catheterization. Five patients had morphological features of Williams' syndrome. One patient had diffuse while the rest had discrete type of supravalvar aortic stenosis. Five patients did not have any associated lesions. A 9-year-old male had an ascending aortic aneurysm, and 3 patients had associated peripheral pulmonary artery stenosis. One child had a subaortic ventricular septal defect, and another had severe mitral regurgitation. Twelve patients had electrocardiographic evidence of left ventricular hypertrophy. Three patients had mild aortic valvar stenosis while 2 had aortic regurgitation. Six patients had dilated coronary arteries. Two patients with supravalvar aortic gradients of 20 and 40 mmHg were kept on close follow-up. One patient was not willing to undergo surgery while the other is awaiting surgery. Eleven patients underwent surgical correction. Dacron or pericardial patch aortoplasty was done in all the patients. In addition, one patient each underwent pulmonary artery plasty, ventricular septal defect closure, repair of ascending aortic aneurysm, and mitral valve replacement. The patient with diffuse type of supravalvar aortic stenosis underwent augmentation aortoplasty. Two patients died perioperatively. One was lost to follow-up. Two had moderate residual gradients. The rest of the patients were in New York Heart Association functional class I on follow-up of 6.3+/-4.7 years. CONCLUSIONS: Repair of supravalvar aortic stenosis by single sinus aortoplasty is safe and produces good results.
