Right ventricular mass: intracardiac ectopic thyroid tissue: a case report.

Ectopic thyroid tissue is a result of abnormal migration of thyroid tissue during the embryonic state. Most of these rare cases, almost 90% of them, are located in the base of the tongue and a minority of them is located anteriorly near the hyoid bone area. Below we report the case of a young patient with an intracardiac mass first diagnosed with three-dimensional echocardiography and afterward successfully treated surgically. Once a careful histological examination has revealed a follicular adenoma, the prognosis is good especially if successful surgical excision is part of the management.

Prenatal diagnsis of intracardiac hamartoma and Turner syndrome.

Turner syndrome is associated with a higher frequency of heart defects detected prenatally when compared to postnatal reports. The most common heart defects detected prenatally are hypoplastic left heart syndrome and coarctation of the aorta. We report a case involving a fetus at 16 gestational weeks with a septated cystic hygroma located on the neck and head, an interventricular septal mass, a hypoplastic left ventricle due to aortic stenosis, mitral stenosis, and a hypoplastic aortic arch with a karyotype of mos 45, X, [47 cells]/47, XXX [3 cells]. The autopsy findings confirmed our prenatal diagnosis with a final diagnosis of Turner syndrome and congenital cardiac vascular malformation.

Subepicardial left ventricular aneurysm with an intraventricular narrow neck on the avascular apical area: report of a case.

A 48-year-old hiatus hernia patient with a history of an occasional epigastric burning sensation for the last 10 years presented with a new onset of chest pain in addition to the persistence of his other symptoms. An apical left ventricular aneurism was found on 64-slice computed tomographic angiography. Coronary angiography confirmed the diagnosis. No coronary lesion was found and the apical region of the left ventricle was avascular. He was operated on under the suspected preoperative possible diagnoses of left ventricular apical aneurysm, a pseudoaneurysm, or a diverticulum. Macroscopically, a subepicardial whitish aneurysmal region with a weakened wall was seen at the apical part of the left ventricle. The size of the lesion was 3 x 3 cm. The aneurysm did not have an extracardiac neck. When the aneurysm site was opened, a sclerotic aneurysm wall and a narrow neck below the incised sac was found; and the neck was communicating with the left ventricular cavity. The aneurysm site was resected and closed with a linear closure technique by using pledget-supported sutures. The termination of cardiopulmonary bypass was uneventful. The patient left the intensive care unit on the first postoperative day and was discharged from hospital on the 4th postoperative day. A subepicardial left ventricular aneurysm should therefore also be considered in the differential diagnosis of atypical chest pain.

Emergency management of severe right ventricular inflow obstruction secondary to a metastatic cardiac tumor.

We report the case of a 21-year-old female with previous history of primitive neuroectodermal tumor of the anterior abdominal wall who developed severe manifestations of right heart failure due to a mass obliterating the right ventricular cavity. She underwent emergent resection of the mass with histopathologic confirmation of metastatic neuroectodermal tumor. To the best of our knowledge, this is the first case of emergent surgical excision of a metastatic cardiac tumor of primitive neuroectodermal origin.
