title: Surgical correction of cor triatriatum sinister in the paediatric population: mid-term results in 15 cases.
abstract: OBJECTIVE
  Cor triatriatum sinister (CTS) is a rare developmental cardiac abnormality resulting in left ventricular inflow obstruction. In this report, we aimed to present our mid-term results of early childhood patients operated for CTS and associated cardiac abnormalities.
  
  
  METHODS
  We enrolled 15 patients with CTS who were operated by a single surgeon between 2001 and 2013. A retrospective analysis was performed in order to determine the demographics, operative and postoperative results of the patients. The median age was 14 months and the median body weight was 8.2 kg at the time of operation.
  
  
  RESULTS
  Fourteen patients had concomitant cardiac pathology. Three of the patients had atrial septal defect and 1 of the patients had partial abnormal pulmonary venous connection, whereas 4 of the patients had both. In 2 cases of complete atrioventricular septal defect, 1 case with ventricular septal defect, 1 case with patent ductus arteriosus, 1 case with double outlet right ventricle and another case with tetralogy of Fallot, complete repair was performed together with membrane resection in the left atrium (LA). The mean preoperative left atrial gradient was 13.3 mmHg, whereas the mean LA pressure at the first postoperative year was 4.2 mmHg. There was 1 case with early mortality due to septic multiorgan failure secondary to pneumonia.
  
  
  CONCLUSIONS
  CTS is a rare congenital cardiac anomaly in which the results of the corrective surgery are encouraging. Early and long-term outcomes may be variable according to the associated congenital heart defects.
