Diagnosis and treatment of right ventricular overload in high risk populations

Abstract

Right ventricular (RV) dysfunction is important

determinant of prognosis in patients at increased risk for development of RV

overload. RV dysfunction in patients before and after surgical left

ventricular restoration is associated with a worse prognosis. RV overload in liver transplantation recipients was also associated with decreased survival. Furthermore, patients with congenital heart disease and an systemic RV are at increased risk for long-term complications caused by RV overload. No unique golden standard for the quantification of RV dysfunction exists. The combination of echocardiographic RV parameters yields additional prognostic information in heart failure patients undergoing surgical left ventricular restoration. In systemic sclerosis the electrical ventricular gradient can accurately detect RV overload and is consistent with other screening parameters in patients with limited organ involvement. Optimization of loading conditions can improve clinical status and RV function in patients with RV dysfunction. RV function can be improved in LVAD patients by optimizing the synergy between the LVAD and intrinsic cardiac function. Furthermore, interventions in complex congenital heart disease patients with pulmonary hypertension can improve RV loading conditions and true pulmonary flow and can improve RV loading conditions and clinical functioning.
