          Abstract

          We present the case of a 55‐year‐old female marathon runner who presented with progressive exercise intolerance and was diagnosed with effusive‐constrictive pericarditis. Stereotypical findings of this challenging diagnosis are shown by transthoracic echocardiographic and right heart catheterization. We treated the patient with a parietal pericardiectomy and pericardial waffle procedure to relieve a thick and constrictive epicardium.

          Validation of Waffle procedure for constrictive pericarditis with epicardial thickening.

          Waffle procedure, a small grid-like incision of epicardium, is a surgical technique for constrictive pericarditis with epicardial thickening. Yet evidences to endorse this approach for improved outcomes are lacking. The aim of this study is to elucidate better surgical treatment strategy for constrictive pericarditis with epicardial thickening.

            For what type of constrictive pericarditis is the waffle procedure effective?

            The waffle procedure is performed in patients with marked thickening and calcification of the epicardium and no substantial improvement in hemodynamic parameters after pericardiectomy. We retrospectively investigated the efficacy of the waffle procedure in 6 of 11 patients who underwent pericardiectomy. These 6 patients showed no improvement in central venous pressure, pulmonary arterial pressure, pulmonary capillary wedge pressure, or cardiac index after pericardiectomy. After the waffle procedure, all hemodynamic parameters improved, and there were no significant differences compared to those of the 5 patients who did not require the waffle procedure, despite higher pulmonary capillary wedge pressure and lower cardiac index values preoperatively in the waffle group. The waffle procedure was considered effective in patients with persistent epicardial constriction.
