Neonatal repair of left atrial diverticulum with gigantic thrombus without cardiopulmonary bypass

Cardiac myxomas may have different clinical presentations that may expose the patient to sudden death due to obstruction of the left ventricle inflow. The authors report a case of 34 years old male who was diagnosed with left atrial myxoma that presented as mitral valve obstruction with severe pulmonary hypertension. He underwent emergent sternotomy under cardiopulmonary bypass and the myxoma was successfully removed. The postoperative course was uneventful.

Pericardial Mass

Cowden syndrome (CS) is a rare disorder characterised by multiple non-cancerous, tumour-like growths called hamartomas. The syndrome is associated with the development of cancer of the breast, endometrium, kidneys, skin and rarely the brain. We report a rare case of symptomatic cardiac haemangioma in a patient with CS. A 54-year-old woman with CS presented with dyspnoea and orthopnoea in the setting of cardiac tamponade. Echocardiography revealed a large haemopericardium and tamponade physiology, secondary to a pericardial mass. The patient underwent urgent cardiopulmonary bypass with removal of the mass. Histopathology confirmed a benign cavernous haemangioma. We postulate that tumours involving the heart/pericardium may be an additional manifestation of CS. This case further highlights the necessity to consider pericardial/cardiac manifestations in patients with hamartomatous syndromes who present with cardiorespiratory symptoms, so that opportunistic investigation and treatment may be instituted.

Male Patients

Forty-four patients with left atrial myxoma were operated at Türkiye Yüksek İhtisas Hospital between 1971 and 1996. There were 31 female and 13 male patients. The myxoma arose from the interatrial septum in 43 patients and from the annulus of the posterior leaflet of the mitral valve in one patient. Preoperatively, all patients had dyspnea or tachycardia. Clinical evidence of systemic embolism was detected in 9 patients. The diagnosis was established by angiocardiography in 6 patients and by echocardiography in 38 patients. All patients were treated surgically under cardiopulmonary bypass and the myxomas were resected with their septal attachments. The septal defects were closed with a patch in 12 patients and primarily in 32 patients.
