    Abstract:
    In order to know early and late results of pericardiectomy on the treatment of chronic constrictive pericarditis in the Instituto Nacional de Cardiología Ignacio Chávez, we review the records of 58 patients with the diagnosis of constrictive pericarditis who underwent surgical treatment between 1947 to 1987. Tuberculosis was the most frequent cause (68.3%) followed by idiopathic cases (24.1%). Preoperatively 3.4% were in New York Heart Association Class I, 31% in Class II, 48.3% in Class III and 17.2% in Class IV. There were 4 in-hospital deaths (overall operative mortality 6.89%). Operative mortality in the last ten years was 0%. Low output was the most common nonfatal complication of pericardiectomy (15.5%). Accidental right atrial tear happened in 8.6%. Mean post-operative follow-up was 5.6 +/- 6.3 years (longest 25.6 years). Mortality per patient year was 2.04%. Actuarial survival estimates were 82% and 71% at 5 to 10 years respectively. Postoperatively 76% were in New York Heart Association Class I (p less than 0.001), 16% in Class II (p less than 0.001), 8% in Class III (p less than 0.001) and none in Class IV (p less than 0.05). Operative mortality, long-term survival and post-operative functional Class were not significantly influenced by preoperative functional Class nor by the duration of symptoms. We conclude that pericardiectomy is an effective treatment of symptomatic chronic constrictive pericarditis because it provides an important and durable improvement in symptoms and functional Class, and it has a low operative mortality.
