Percutaneous pulmonary and tricuspid valve implantations: An update

Table 2 Clinical and morphological requirements for percutaneous pulmonary valve implantation

Clinical indications in the context of RV pressure overload/pulmonary stenosis

RV systolic pressure > 65% of systemic pressure in symptomatic patients

RV systolic pressure > 75% of systemic pressure in asymptomatic patients

Clinical indications in the context of RV volume overload/pulmonary regurgitation

Severe pulmonary regurgitation on echocardiography or MR imaging and

Severe RV dilatation > 150 mL/m2 or the RV to LV end-diastolic ratio of > 1.7 and/or

Rapid progressiv RV dilatation and/or

Severe RV dysfunction and/or

Symptoms and/or

Circumferential RV to PA conduit with dimension at surgical implantation of at least 18 mm but no larger than 29 mm (with some degree of conduit narrowing) (SAPIENTM)

Exclusion of risk for coronary compression

RV: Right ventricle; PA: Pulmonary artery.
