Stenting of a left main coronary artery compressed by dilated pulmonary artery

Total Occlusion of Left Main Coronary Artery by Dilated Main Pulmonary Artery in a Patient with Severe Pulmonary Hypertension

A 34-year-old woman was admitted to the hospital because of recently aggravated right heart failure without angina for 5 months. When she was 25 years old, patch repair with Polytetrafluoroethylene (PTFE) was performed for the secondum type of atrial septal defect (ASD) with moderate pulmonary hypertension. The chest PA, echocardiography and cardiac catheterization at current admission revealed...

Left main coronary artery compression by an enlarged pulmonary artery.

Simultaneous Coronary and Pulmonary Angiography to Diagnose Critical Left Main Coronary Artery Stenosis Secondary to Dilated Pulmonary Artery.

A 68-year-old woman with long-standing severe pulmonary arterial hypertension was referred for coronary catheterization for investigation of worsening exertional dyspnea associated with angina. Coronary angiography revealed critical ostial left main coronary artery (LMCA) stenosis. Given the history of severe pulmonary arterial hypertension, simultaneous angiography of the LMCA and main pulmona...

Stenting of unprotected left main coronary artery stenosis.

Unprotected left main stenosis greater than 50% has traditionally been managed with coronary artery bypass surgery. There is now emerging evidence to support a percutaneous strategy adopting drug-eluting stents, especially in patients at high risk for surgery. This paper will review recent outcomes of both bare-metal and drug-eluting stent use for unprotected left main stenosis and summarise re...

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.
