Subpulmonary Right Ventricle in Congenital Heart Disease
Fig. 5.1 (a) Prenatal ultrasound performed in a fetus of 30 gestational weeks depicts a four-chamber view with a tripartite right ventricle. (b) Two weeks later in the 32 gestational…
The Right Ventricle in Left Heart Failure
Fig. 17.1 Kaplan–Meier plots for all-cause mortality (a) and HF hospitalization (b) by RV ejection fraction categories [11]. (with permission Meyer P, Filippatos GS, Ahmed MI, et al. Effects of…
The Pathobiology of Chronic Right Ventricular Failure
Fig. 13.1 Hemodynamic stress causes morphological changes of the heart and the central vessels which are initially adaptive (upper box). These factors affect the fate of the myocardial cells (lower…
Missing a Sub-pulmonary Ventricle: The Fontan Circulation
Fig. 8.1 Schematic representation of the normal cardiovascular circulation (a), shunted palliation (b), and Fontan circulation (c). (a) Normal circulation: the pulmonary circulation (P) is connected in series with the…
Exercise-Induced Right Heart Disease in Athletes
Fig. 15.1 A consistent relationship between increases in pulmonary artery pressures and cardiac output during exercise. Echocardiographic estimates of pulmonary artery pressures (PAP)—panels (a) and (b)—demonstrate a near-linear relationship between…
Animal Models of Chronic Right Ventricular Stress and Failure
Fig. 22.1 Surgical procedure to place pulmonary artery banding. Pulmonary artery is dissected free from the aorta (a) white arrow and then a silk thread is positioned behind the pulmonary…
Right Ventricular Assist Devices

The Sick Lung Circulation and the Failing Right Ventricle
Fig. 14.1 Pulmonary venous and arterial remodeling in left heart disease. This schematic puts the emphasis on the damaged lung capillaries Hypothesis of the Lung Circulation and the Heart as…
Acute Right Ventricular Failure
Fig. 9.1 Mechanisms of acute RV failure. Acute RVF frequently is multifactorial and includes a number of pathological conditions that result in reductions in RV contractility and preload, in addition…
Advanced Imaging of the Right Ventricle
Fig. 4.1 Representative intraventricular blood flow profiles of the right (RV) and left ventricle (LV) at diastole and systole in a healthy control. The main trajectories of blood flow are…
