Perventricular Closure of Muscular Ventricular Septal Defects in Infants With Echocardiographic Guidance Only

Abstract

Objective: To report our experience with perventricular closure of muscular (apical) ventricular septal defects (VSDs) in small infants, with echocardiographic guidance only, in a nonhybrid suite. Methods: Eight infants with nine large muscular (apical) VSDs underwent perventricular device closure in a nonhybrid operating room, with transesophageal and epicardial echocardiography guidance, at a mean age and weight of 3.07 (0.3-7.28) months and 3.7 (2.5-6.2) kg, respectively. Five patients had multiple VSDs. Four had associated cardiac defects. Results: Nine Amplatzer muscular VSD devices with a mean size of 10 (4-14) mm were deployed. Seven patients were discharged from the intensive care unit with a mean length of stay of 8.6 days. Four patients had minimal postprocedural residual shunt; no one had a residual shunt at six-month follow-up. Mid-term results are excellent. Conclusion: Perventricular closure is feasible under echocardiographic guidance only in small patients, even without hybrid suite. This may be a good approach for very symptomatic low-weight infants with apical VSD and may also be useful, in any center, at any time, and in any operating room, to treat an associated apical VSD, even unexpected.
