Left main coronary artery compression syndrome caused by pulmonary artery and noncoronary sinus aneurysm dilatation

Síndrome de compresión del tronco coronario izquierdo por dilatación de la arteria pulmonar y del aneurisma del seno no coronario

Dyspnea is the main symptom among patients with pulmonary arterial hypertension, however, in daily practice it is common to find some whose most significant manifestation is angina pectoris (47%). An extrinsic obstruction of the left main coronary artery caused by coronary sinuses aneurysmal dilatation plus pulmonary artery dilatation, is unusual, with few cases reported in the literature. We present a patient with chronic thromboembolic pulmonary hypertension who consulted for dyspnea, documenting pulmonary artery and aneurysmal noncoronary sinus dilatation, significantly involving the left main coronary artery.
