Abstract

OBJECTIVE

The objective of this study was to test the hypothesis that limited (<1 cm) right ventriculotomy (RV-tomy) in the setting of transannular tetralogy of Fallot (TOF) repair might result in less right ventricular (RV) dilatation and dysfunction compared with conventional RV-tomy.

METHODS

Between June 2002 and April 2012, 113 patients with transannular repair of TOF underwent magnetic resonance imaging (MRI). Patients were divided into a limited RV-tomy group (n = 39) and a conventional RV-tomy group (n = 74). Thirty-nine patients from each group were matched for comparison using propensity scores. The MRI parameters of the 2 groups were compared.

RESULTS

The interval between TOF repair and MRI examination was shorter in the limited RV-tomy group (limited, 12.7 ± 3.8 years; conventional, 17.2 ± 4.7 years; P < .001). Indexed RV volumes were similar between the groups (RV end-diastolic volume index: 149 ± 31 mL/m(2) vs 152 ± 42 mL/m(2); P = .704. RV end-systolic volume index: 70 ± 24 mL/m(2) vs 77 ± 38 mL/m(2); P = .313). There was no difference in the RV ejection fraction between the groups (54% ± 9% vs 51% ± 9%; P = .160). Propensity score-matched comparison also revealed no differences in RV volume and function.

CONCLUSIONS

No long-term benefits of limited RV-tomy were demonstrated compared with conventional RV-tomy in patients who underwent transannular TOF repair, at least in terms of RV volume and function. Further studies are necessary to define the role of limited RV-tomy in patients who undergo transannular TOF repair.
