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

Abstract

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. 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. 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. 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.
