Constrictive epicarditis after open heart surgery: the turtle cage operation.

A 60-year-old man developed constrictive epicarditis within 1 year after isolated mitral valve replacement (MVR). At reoperation, decortication of the thick epicardial layer resulted, impossible without a high risk of injury of the myocardium and major coronary arteries. Therefore, multiple longitudinal and transverse incisions were performed on the epicardial peel, which at the end acquired a turtle cage appearance allowing myocardial reexpansion, relief of constriction, and restoration of adequate hemodynamics.
