Ministernotomy versus full sternotomy in congenital heart defects: a prospective randomized study.

Abstract

BACKGROUND:

Although the ministernotomy is extensively used in the repair of congenital heart defects all over the world, whether this approach has additional advantages over the conventional full sternotomy is not well established. This prospective study was designed to evaluate the effects of lower ministernotomy in the repair of congenital heart defects.

METHODS:

One hundred patients who underwent repair of atrial or ventricular septal defects were randomly divided into two groups: lower ministernotomy group (n = 50), and full sternotomy group (n = 50). The clinical indexes of each procedure were recorded and analyzed.

RESULTS:

The age, sex, and types of cardiac defects were comparable between the two groups. Ischemic times, bypass times, intensive care unit stay, and ventilation duration were similar in both groups. The procedure time (from skin to skin) was longer in the lower ministernotomy group than in the full sternotomy group (p < 0.001). There was less drainage in the lower ministernotomy group than in the full sternotomy group for the first 24 hours after operation (186 +/- 99 mL/m2 versus 237 +/- 134 mL/m2, p = 0.03) but no significant difference in transfusions between the two groups. The hospital stay was shorter in the lower ministernotomy group than in the full sternotomy group (6.5 +/- 1.2 days versus 7.5 +/- 1.8 days, p = 0.02).

CONCLUSIONS:

Ministernotomy is as safe and effective as a full sternotomy in the repair of simple congenital heart defects in older children and adults. Furthermore, this small incision reduces the postoperative drainage, shortens hospital stay, and provides better cosmetic results. Operative times are longer.
