Right Ventricle and Exercise Capacity

Right Ventricle and Exercise Capacity

Almost 3 quarters of a century ago, an experimental dog model, involving the electrocautery ablation of the free wall of the right ventricle (RV), served as the basis for the contention that the RV serves functionally as a passive conduit. Clearly, our understanding of the RV has evolved over subsequent decades, and the prognostic significance of RV dysfunction is now recognized in a wide array...

Exercise training improves exercise capacity in adult patients with a systemic right ventricle: a randomized clinical trial.

OBJECTIVE To assess whether exercise training in adult patients with a systemic right ventricle (RV) improves exercise capacity and quality of life and lowers serum N-terminal prohormone brain natriuretic peptide (NT-proBNP) levels. DESIGN Multi-centre parallel randomized controlled trial. PARTICIPANTS Patients with a systemic RV due to congenitally or surgically corrected transposition of ...

Adaptive capacity of the right ventricle: why does it fail?

Only in recent years has the right ventricle (RV) function become appreciated to be equally important to the left ventricle (LV) function to maintain cardiac output. Right ventricular failure is, irrespectively of the etiology, associated with impaired exercise tolerance and poor survival. Since the anatomy and physiology of the RV is distinctly different than that of the LV, its adaptive mecha...

Double outlet right ventricle.

Double-chambered right ventricle.

Thirty (10.8%) of 279 patients undergoing correction of a ventricular septal defect (VSD) from January, 1972, to September, 1986, also had a double-chambered right ventricle (DCRV). Age at operation ranged from 1.3 to 18.8 years (mean, 6.7 +/- 4.5 years [+/- standard deviation]). Seventeen patients were male, and 13 were female. Two-dimensional echocardiography was used after 1978 in the initia...
