Sign Up to like & getrecommendations! Published in 2019 at "Pediatric Cardiology"
DOI: 10.1007/s00246-019-02091-6
Abstract: The single right ventricle (RV) in hypoplastic left heart syndrome (HLHS) often develops systolic dysfunction with time and this affects prognosis. Mechanical dyssynchrony has been reported in HLHS but has not consistently correlated with systolic… read more here.

DOI: 10.1007/s00380-020-01664-3
Abstract: Diastolic intraventricular pressure difference (IVPD) reflects left ventricular (LV) diastolic function. The relative pressure imaging (RPI) enables the noninvasive quantification of IVPD based on vector flow mapping (VFM) and visualization of regional pressure distribution. LV… read more here.
