Left main coronary artery systolic compression by a dilated pulmonary artery: intravascular ultrasound assessment of the milking phenomenon

Left main coronary artery compression by an enlarged pulmonary artery.

Systolic compression of left main coronary artery by left ventricular pseudoaneurysm complicated by critical stenosis of left main coronary artery

A 69-year-old man was admitted to the hospital with complaints of exertional substernal chest pain and dyspnea for 3 weeks. His medical history consisted of dyslipidemia, type 2 diabetes mellitus, and valvular heart disease. He had a mitral commissurotomy through a left thoracotomy for mitral stenosis at age 16 years followed by mitral valve replacement with a 25 mm Carpentier Edwards bovine pe...

Intravascular ultrasound to assess left main stem coronary artery lesion.

A man of 70 underwent coronary arteriography for the assessment of angina. The appearance of the left coronary main stem was slightly abnormal but no definite stenosis could be delineated. Intracoronary ultrasound examination with a 4.8 French intravascular ultrasound probe showed an extensive plaque in the distal left main stem and proximal left anterior descending coronary artery, with a shel...

Spontaneous coronary artery dissection involving the left main stem: assessment by intravascular ultrasound.

This case report describes the devastating consequences of spontaneous coronary dissection in a 36 year old female patient who otherwise had a normal coronary arteriogram. Intravascular ultrasound showed coronary artery dissection and intramural haematoma at the left main stem coronary artery. Acute coronary syndrome developed and subsequently surgical revascularisation was performed successfully.

Left main coronary artery and right pulmonary vein compression by a large pulmonary artery aneurysm.

Pulmonary artery aneurysms are uncommon and may be associated with significant morbidity and mortality. The unique combination of left main coronary artery and upper right pulmonary vein compression by a large pulmonary artery aneurysm is reported. Furthermore, the aetiology, clinical manifestations, complications, diagnostic approach, and possible therapeutic interventions are briefly discussed.
