Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Tricuspid regurgitation and the right ventricle in risk stratification and timing of intervention

Echo Research and Practice, 2019
Tricuspid regurgitation natural history and treatment remains poorly understood. Right ventricular function is a key factor in determining prognosis, timing for intervention and longer-term outcome.

Circulating Progenitor and Apoptotic Progenitor Cells in Patients With Aortic Regurgitation

Circulation Journal, 2013
Endothelial progenitor cells (EPCs) have a role in the repair of endothelial surfaces after injury. Reduced numbers of EPCs are related to endothelial dysfunction and adverse clinical events, suggesting that endothelial injury in the absence of sufficient repair by circulating EPCs promotes the progression of vascular disease or valvular disorder.
