Abstract:
Introduction Surgical outcomes for simple ventricular septaldefects (VSD) have been excellent in the past three decades. Forthis project, the timing of resolution of left-sided dilation and mitralregurgitation (MR) following VSD repair was assessed. Methods Echocardiographic data surrounding surgery of 42 consecutivechildren who underwent surgical patch repair of a VSD werereviewed. The echocardiograms were reviewed up to a mean of 12months post-operatively (range 9 - 14 months). Quantitative dataindexed to body surface area including left atrial (LA) volume, mitralvalve annulus diameter, and left ventricular end-diastolic dimension(LVEDD) was analyzed. Results The majority of our pre-surgical cohort had only trace(44%) or no MR (31%), with a small proportion having mild (16%)or moderate MR (9%). No patients had moderate or greater MR followingrepair at follow-up. The median mitral valve annular Z-scorewas 1.8 (SD 1.6; range: -1.2 to 4.1) pre-operatively, improving to a 0.6(range: -1.7 to 2.4; p 〈 0.001) at follow-up. LA dilation was present in70% of patients, with a median LA volume Z-score of 1.1 (range: -2.6to 15.5), decreasing to 13% median Z-score -1.2 (range: -3.5 to 2.9; p 〈 0.001) at follow-up. LV dilation was present in 81% of pre-operativepatients with a median LVEDD Z-score of 3.0 (range: -2.0 to 7.9).There was significant improvement in qualitative assessment of LVenlargement (25%) with a median LVEDD Z-score of 0.5 (range:-2.1 to 2.9; p 〈 0.001) at follow-up. Discharge echocardiogram wasperformed at a mean of 5.7 days (range: 3 - 12 days) following surgery. Conclusions Normalization of LA, mitral valve annulus, and LV sizeoccurred within the first three months in the majority of patients, withsignificant changes occurring within the first post-operative weekfollowing surgical repair for VSD.
