“…In patients undergoing cardiac catheterization, the incidence of STEMI caused by LMCA ranges between 0.8% and 2.5% [ 2 , 5 , 6 ]. Since it feeds much of the myocardium, the acute occlusion of LMCA usually presents as a massive infarction [ 7 ]. It causes major complications like CS, arrhythmias, and rapid hemodynamic deterioration, which result in adverse outcomes.…”

Acute total occlusion of the left main artery is a fatal event and is often accompanied by cardiogenic shock. Patients who experience this event have high mortality rates. Early percutaneous coronary intervention (PCI) with hemodynamic support has proven to improve clinical outcomes for these patients. Here we report a case of a 60-year-old man, who came into our emergency room with an acute anterior wall myocardial infarction accompanied by cardiogenic shock. He had a totally occluded left main artery on coronary angiography, necessitating cardiopulmonary resuscitation, followed by PCI with implantation of a drug-eluting stent along with hemodynamic support. Identification of typical ECG changes is crucial in patients with acute coronary syndrome caused by the occlusion of the left main coronary artery. A quick decision to perform a PCI procedure using early circulatory mechanical devices (intra-aortic balloon pump) is critical to patient survival.

“…LMCA occlusion is usually rare. While acute occlusion of the LMCA presents with anterior myocardial infarction, pulmonary edema, and cardiogenic shock, cases with chronic occlusion usually present with symptoms of angina [4,5]. Considering the previous studies, LMCA occlusion occurs in the 14-87-year age range.…”

Chronic Total Occlusion of the Left Main Coronary Artery With Preserved Left Ventricular Systolic Function Presenting as a Chronic Coronary Syndrome: A Case Report and Brief Review

The incidence of lesions involving the left main coronary artery (LMCA) during coronary angiography is approximately 5% to 8%. It usually presents with acute coronary syndrome and can be fatal. Total occlusion of the LMCA is rare, often accompanied by myocardial infarction and cardiogenic shock. We present an LMCA chronic total occlusion case in a 60-year-old female patient with chronic coronary syndrome. In our case, the LMCA was selectively visualized, and it was found to be occluded. The right coronary artery fed the entire left system through the collateral network. The patient had no risk of coronary artery disease other than hypertension. Successful coronary artery bypass grafting was performed without any complications.

“…LMCA occlusion usually presents as ACS. Since LMCA supplies 75% of the LV in right dominant circulation and 100% in left dominant circulation, acute LMCA occlusion usually presents as massive infarction and cardiogenic shock and is associated with a high mortality rate 5 …”

Significant left main coronary artery (LMCA) disease is found in 5–6% of all patients undergoing coronary angiography. It usually presents as acute coronary syndrome and is commonly associated with multi-vessel coronary artery disease (CAD). Complete occlusion of LMCA is a much rarer finding, since these patients usually present as unstable angina, myocardial infarction and cardiogenic shock. We report a case of a young female, who presented with chronic stable angina and had an isolated chronic total occlusion (CTO) of LMCA with no lesions in the other coronary arteries. Aortogram failed to demonstrate the stump of occluded LMCA and demonstrated the filling of the left coronary system from the right coronary artery. Apart from dyslipidemia, she had no other risk factors for CAD. She was extensively evaluated for non-atherosclerotic causes of LMCA CTO including vasculitis. She underwent coronary artery bypass graft successfully without any peri-procedural complications.
