Key result
Staged left ventricular rehabilitation with endocardial fibroelastosis resection did not acutely change QRS duration (median change 0 ms, p=0.09), though long-term conduction delay occurred in 44%.

Does endocardial fibroelastosis resection affect ventricular conduction and QRS duration in patients with borderline hypoplastic left cardiac syndrome?
p-value: p=0.09
Electrical dyssynchrony is common long-term after staged left ventricular rehabilitation for hypoplastic left heart syndrome, correlating with LV size rather than acute surgical resection.
Czosek et al. (2010) conducted a cohort in borderline hypoplastic left cardiac syndrome (n=27). Staged left ventricle rehabilitation with endocardial fibroelastosis resection was evaluated on Change in QRS duration in the immediate period after endocardial fibroelastosis resection (p=0.09). Staged left ventricular rehabilitation with endocardial fibroelastosis resection did not acutely change QRS duration (median change 0 ms, p=0.09), though long-term conduction delay occurred in 44%.
