Abstract :

Background & Aim: Long standing ostium secundum atrial septal defects lead to functional tricuspid regurgitation. Significant functional tricuspid regurgitation associated with left heart valve diseases are addressed at the time of primary left heart valve surgery. On the contrast, there is no global recommendation in accordance with tricuspid regurgitation associated with atrial septal defects. This study assesses the changes in tricuspid regurgitation after isolated atrial septal defect closure.

Method: Retrospectively, 97 patients who underwent isolated ostium secundum atrial septal defect closure without tricuspid valve repair, was followed up. Echocardiograms were done pre-operatively, on 3rd post-operative day, 3 months and 1 year. Data on tricuspid regurgitation status, right ventricle dimensions and pulmonary artery hypertension status were collected and analyzed.

Result: After the surgical closure, echocardiogram showed a regression of tricuspid regurgitation to less than mild in 76% of patients on 3rd post-operative day, 89% at 3 months and 93% at 1 year. Pulmonary artery hypertension (32% patients preoperatively) showed statistically significant regression with 14% on 3rd post-operative day, 10% at 3 months and 2% at 1 year. Preoperatively the mean right ventricular internal diameter was 37.9 mm which regressed to 34±5.5 mm on 3rd post-operative day, 32.3±5.3 mm at 3 months and 31.3±5.4 mm at 1 year. It was also noted that regression favored patients who are less than 25 years.

Conclusion: Tricuspid valve repair may not be required in patients with ostium secundum atrial septal defect with functional tricuspid regurgitation.
