Key result
LMCA compression by dilated PA carries dismal outcomes and must be ruled out in PH.
Why the study?
Left main coronary artery compression is an underrecognized condition in patients with pulmonary artery hypertension that may lead to dismal outcomes.
Highlights the clinical necessity to rule out left main coronary compression in young patients with pulmonary hypertension or those with hugely dilated pulmonary arteries presenting with angina.
Supports consideration of LMCA compression in PH patients with angina; hypothesis-generating and requires prospective validation.
Left main coronary artery compression is an underrecognized condition in patients with pulmonary artery hypertension. If present, it may lead to dismal outcome. In young patients with pulmonary hypertension or in patients with hugely dilated pulmonary artery with symptoms of angina, left main coronary compression must be ruled out.
