Síndrome de ortodeoxia-platipnea y embolia luego de endocarditis derecha complicada: consecuencias del Foramen Oval Permeable / Platypnea-Orthodeoxia syndrome and embolism after complicated right side endocarditis

Se presenta el caso clínico de una mujer de 63 años de edad con Endocarditis de la Válvula Tricúspide que desarrolló tromboembolismo pulmonar y un síndrome de platipnea-ortodeoxia explicado por la presencia de un formen oval permeable. La paciente se recuperó satisfactoriamente después de un reemplazo de la válvula tricúspide.

The case of 63 year old woman with Endocarditis at the Tricuspid Valve, pulmonary and paradoxical embolism with platypnea-orthodeoxia syndrome is presented. The patient recovered after surgical replacement of the tricuspid valve.

A Case of Cardiac Papillary Fibroelastoma in a Tricuspid Valve / 日本心臓血管外科学会雑誌

Cardiac papillary fibroelastoma (CPFE) is a rare tumor, and is usually located in the atrioventricular or ventriculoarterial valves. It is occasionally identified by echocardiography or surgery. It can also be an unexpected finding at autopsy. As this tumor often occurs in left-sided cardiac chambers, early aggressive surgical resection is required in order to prevent severe systemic embolic complications. However, the operative indications of tumors on the right cardiac chamber are controversial. The patient was a 73 year-old man. He had had cerebral infarction at age 58. Before the currently reported operation, we found CPFE on the tricuspid valve but we could not find a patent foramen ovale (PFO) by the usual examinations. During surgery, we found a CPFE on the tricuspid valve that had a short stalk and PFO. We cut the short stalk of the CPFE easily, and closed the PFO directly. This patient did not need complicated valve repair. We speculated that this cerebral infarction was caused by a CPFE on the tricuspid valve and patent foramen ovale. Echocardiography is very useful in diagnosing CPFE. However, we should not neglect the possibility of PFO before surgery. The postoperative course was uneventful. We concluded that early surgical resection of CPFE, even in right-sided cardiac chambers, should be performed in order to prevent severe embolic complications, even without PFO diagnosis.
