Ventricular-arterial coupling: A novel echocardiographic risk factor for pediatric dilated cardiomyopathy

Ventricular-arterial coupling, earlier used for research and experimental purposes, is being used currently for bedside patient evaluation and decision making. Its use in adults with heart failure has been proven. In pediatric heart failure, due to dilated cardiomyopathy, its use as a prognostic tool has been first documented in this study, and cutoff values determining outcome, have been derived.
