Abstract

Background

We evaluated midterm results of transatrial repair of TOF with a stress on follow-up studies by echocardiography and exercise testing.

Method

Out of a total of 235 patients undergoing transatrial repair of TOF between January 2001 and January 2011 by a single surgical team, 59 patients consented for this study. Mean follow-up was 6.10 ± 1.86 years (median-5.50, range 4.50 years to 12.60 years).

Results

One patient had residual VSD and one patient required re-operation for residual right ventricular outflow tract (RVOT) obstruction. Mean RVOT gradient was 13.36 ± 7.99 mmHg. Thirty-three (55.9 %) patients were free of any pulmonary regurgitation. Mean right ventricular myocardial performance index was 0.35 ± 0.06. Tricuspid annular plane systolic excursion and systolic tricuspid lateral annuli velocity (s′) were 16.75 ± 2.57 and 10.82 ± 1.64, respectively, and were suggestive of normal right ventricular systolic function. The mean maximum oxygen uptake (VO2) max was 42.35 ± 6.55 which is higher than previously reported values of patients with repaired TOF.

Conclusion

Transatrial repair for TOF offers good mid- to long-term hemodynamics, preserves the right ventricular systolic and diastolic function, and preserves the exercise tolerance capacity.
