Carney complex (CNC) is a familial multiple neoplasia syndrome characterized by cardiac and extracardiac myxomas in the setting of spotty skin pigmentation and endocrinopathy. We previously identified PRKAR1A (regulatory subunit 1alpha of protein kinase A) mutations in CNC. Mutational analyses of the PRKAR1A gene in 51 unrelated CNC probands now detect mutations in 65%. All mutations, except fo...
We report the findings on selective coronary angiography in nine patients with atrial myxomas. The angiograms were obtained because the patients were suspected of having coronary artery disease. In each case, the diagnosis of myxoma had been made earlier by echocardiography. Coronary angiography in five (55%) of the nine patients showed neovascularity in the tumor without calcification. In one ...
Cardiac tumors are an unusual cause of acute limb ischemia. Myxomas are the most frequent benign tumors and most are symptomatic. Embolization occurs in 30% to 40% of patients with myxomas, with cerebral arteries being the most common destination. We present the case of a 73-year-old woman with a history of hypertension who came to the emergency department due to pain and sudden onset of coldne...
Gated radionuclide cardiac blood pool scans (GCS) of end-systole and end-diastole or eight images subtending the entire cardiac cycle were performed on seven patients with left atrial myxomas documented by pulmonary cineangiography with left atrial follow-through. The ethocardiogram was either suggestive or diagnostic in all patients. In addition to demonstration of the tumor (6 patients), the ...
myxomas, the most common primary cardiac tumors, are known as a source of cardiogenic emboli. the possibility of their early detection has made them of great importance for emergency medicines. detection of the disease is probable at early stages using echocardiography and associate complications such as syncope, cerebral embolic ischemic strokes, and sudden death. we report experience of a rar...
Abstract Introduction: Carney complex is a rare autosomal dominant disorder characterized by pigmented lesions of skin and mucosae, endocrine neoplasms or overactivity, myxomas the heart, skin, other organs. Most patients have at least two affected organs time diagnosis. We present case with involvement limited to thyroid gland. Case: A 48-year-old female was referred for evaluation nodules inc...
The clinical and echocardiographic findings of four patients with right ventricular tumors (three myxomas and one metastatic melanoma) are presented. All four patients previously had been evaluated by competent cardiologists, and the diagnosis of a right ventricular tumor was missed. The initial echocardiograms were interpreted as not showing any right ventricular tumor; but on review we found ...
A 45-year-old male, who had been indicated by brain magnetic resonance imaging to have cerebral infarctions, was found by echocardiography to have a tumor in the left atrium. He had experienced several of the constitutional disturbances associated with myxoma. At the ages of 19 and 35 he had had two episodes associated with embolisms, and at the later one he was diagnosed as having multiple cer...
Myxomas are the most common benign cardiac tumors. Myxomas are more common in the left heart chamber than the right side chamber. An extracardiac origin presenting as a right atrial mass is very rare. We present a case of myxoma originating in the superior vena cava (SVC) in a 24-year-old man, who underwent surgical resection. Preoperative two-dimensional echocardiography demonstrated a mass in...
