A Case of Severe Tricuspid Regurgitation Mimicking Constrictive Pericarditis / 日本心臓血管外科学会雑誌

We report a surgical case of severe tricuspid regurgitation with hemodynamic features mimicking constrictive pericarditis. A catheterization study showed a dip and plateau pattern of right and left ventricular pressure. Intraoperative finding : the pericardium was not adherent to the epicardial wall. The tricuspid regurgitation was successfully repaired by cleft suture and tricuspid annuloplasty. After surgery, the echocardiographic features mimicking constrictive pericarditis were normalized.
