Answer
Answer e.
PHT is defined as PA pressure > 25 mmHg at rest (or > 30 mmHg
during exertion) with a normal pulmonary wedge pressure. Definition by
echocardiography is considered to be systolic PA pressure > half systolic systemic
pressure. Other echo findings that suggest high-risk include tricsupid
regurgitation jet > 4 m/sec, RV dilatation and LV compression.
