Abstract/OtherAbstract:
OBJECTIVES: To test the hypothesis that left ventricular (LV) dilation associated with pressure-restrictive ventricular septal defect (VSD) often remains stable or regresses spontaneously, calling into question the role of interventional management for such defects. STUDY DESIGN: We analyzed 96 serial echocardiograms from 33 unoperated patients with a moderate-to-large VSD with LV dilation (LV end-diastolic dimension [LVED] z score >2.0) at enrollment who were followed for more than 2 years. Records of 125 surgical patients also were reviewed. Patients were evaluated for evidence of persistent or progressive LV dilation; signs or symptoms of congestive heart failure (CHF), failure to thrive (FTT), or pulmonary hypertension (PAH); as well as acquired ventricular outflow obstruction or aortic regurgitation. LVED z scores at enrollment versus latest follow-up were compared using paired t tests. A random-effects model with random intercept and slope was fitted to account for repeated observations for each patient. RESULTS: Mean age at enrollment was 4.6 +/- 3.2 years, and mean follow-up was 7.8 +/- 4 years (range, 2.8 to 22 years), during which mean LVED z score decreased from 3.0 +/- 0.6 to 1.2 +/- 1.3 (P < .01). LVED z score decreased in 29 of the 33 patients, and decreased to <2 in 26 of these 29 (79%). CONCLUSIONS: Most patients with pressure-restrictive VSD with moderate-to-severe LV dilation without CHF, FTT, or PAH will experience spontaneous resolution of LV dilation and can avoid cardiac surgery or catheter-based intervention.
