Resolution of polyserositis after removal of appendix mucinous cystadenoma.

Mucinous cystadenoma is a rare benign neoplasm and is usually discovered incidentally. Pleuritis and pericarditis, inflammation of the pleura and pericardium, may represent manifestations of autoimmune disorders especially in female subjects. We report a patient with polyserositis that was resolved after removal of the mucinous cystadenoma.

Amyloidosis of the aortic root in a patient with polyarteritis nodosa.

Amyloidosis results from the deposition of insoluble fibrillar proteins in various tissues. Cardiac symptoms, when present, are usually related to congestive heart failure or arrhythmias. Amyloid involvement of the aortic root is exceedingly rare.

Aortic valve replacement in a patient with severe hemophilia.

Hemophilia A is an inherited bleeding disorder characterized by factor VIII deficiency. The basis for insufficient hemostasis lies within inadequate amplification of factor Xa production with the undersupplied factor VIII. We report on a young patient with critical aortic stenosis bearing all the clinical stigmata of severe hemophilia, in whom aortic valve replacement was performed with a tissue valve in order to avoid the need for long term anticoagulation.

Echocardiographic diagnosis of anomalous origin of the left coronary artery from the pulmonary artery.

We found increased systolic coronary flow in transthoracic pulsed wave (PW) Doppler in a 42-year-old patient with anomalous origin of left main coronary artery from the pulmonary artery. This is a characteristic echocardiographic finding in this anomaly in the presence of collateral circulation and coronary L-R shunt. In comparison with so far used echocardiographic criteria this parameter when present allows quick recognition of anomalous origin of left coronary artery from the pulmonary artery, and its differentiation from other potentially lethal coronary anomalies.

Giant, dissecting, high-pressure pulmonary artery aneurysm: case report of a 1-year natural course.

We report the rare subchronic clinical course of a giant, dissecting pulmonary artery aneurysm in an oligosymptomatic middle-aged woman who had idiopathic pulmonary hypertension. Diagnosis was simple with the use of echocardiography and multislice computed tomography. Conversely, deciding on the treatment was difficult, because prominent surgeons declined to perform surgical repair of the aneurysm and recommended heart-lung transplantation.
