Cor triatriatum represents <0.1% of all congenital cardiac malformations. Symptoms in patients with cor triatriatum are related to pulmonary venous obstruction and pressure loading of the right side of the heart. The aim of this study was to describe our institutional experience with repair of cor triatriatum. From June 1963 to June 2010, 65 patients underwent repair at a median age of 7.2 months (range 2 days to 47.6 years). Among these patients, 49 (75%) had associated congenital heart defects. Atrial septal defect (n = 29), ventricular septal defect (n = 15), partially or totally anomalous pulmonary venous return (n = 14), mitral valve abnormalities (n = 11), and supravalvar mitral ring (n = 5) were the most common associated defects. Surgical treatment consisted of excision of the membrane, along with additional procedures in 47 patients (72%). Five patients had new postoperative supraventricular arrhythmias. During a median follow-up period of 5.4 years, no patients underwent reintervention for recurrent left atrial obstruction, 7 patients were noted to have minor residual cor triatriatum without obstruction, and 8 patients (including 4 diagnosed before cor triatriatum repair) had pulmonary vein stenosis, 6 of whom underwent intervention for that reason. In conclusion, in this large surgical series of patients who underwent repair of cor triatriatum, there were no cases of significant residual or recurrent cor triatriatum. Although the association between cor triatriatum and pulmonary vein stenosis has been described previously, the relative frequency of this condition in our cohort (>10%, including patients diagnosed before and after cor triatriatum repair) is noteworthy. Abnormalities of the mitral valve and a supravalvar mitral ring were also seen more often than the existing research would suggest, which may be another important consideration in evaluating and following these patients.

ABSTRACT: Cor triatriatum is a rare congenital cardiac defect in which the atrium is divided into 2 chambers by a membrane causing obstruction to the blood flow in either the left atrium (cor triatriatum sinister) or the right atrium (cor triatriatum dexter) eventually leading to cardiac failure. We sought to review our surgical experience with cor triatriatum sinister. Twenty-five patients underwent surgical correction of cor triatriatum between May 1960 and September 2012. There were 11 males and 14 females with a mean age of 27.4 years (age range, 1 day to 73 years). All patients underwent excision of cor triatriatum membrane using cardiopulmonary bypass. Twenty patients (80%) required concomitant cardiac surgical procedures. There was no early mortality. None of the patients had any residual atrial obstruction. Two infants who had concomitant repair of complex congenital anomalies died at 2 and 5 months postoperatively after discharge from hospital. Kaplan-Meier survival at 10 years was 83%. All patients were in New York Heart Association class I or II at a mean follow-up of 12.8 years (maximum 44 years). Surgical repair of cor triatriatum provides satisfactory early and long-term survival with low risk for additional intervention. Cor triatriatum with complex congenital anomalies may be associated with adverse outcome.The Annals of thoracic surgery 03/2014; 97(5). DOI:10.1016/j.athoracsur.2013.12.046 · 3.85 Impact Factor
