The Right Heart-Pulmonary Circulation Unit and Left Heart Valve Disease

Valvular heart disease (VHD) is frequently accompanied by pulmonary hypertension (PH). In asymptomatic patients, PH is rare, although the exact prevalence is unknown and mainly stems from the severity of the VHD and the presence of diastolic dysfunction. PH can also be depicted during exercise echocardiography. PH either at rest or during exercise is also a powerful determinant of outcome and is independently associated with reduced survival, regardless of the severity of the underlying valvular pathology. Therefore, because PH is a marker of poor prognosis, assessment of PH in VHD is crucial for risk stratification and management of patients with VHD.
