Treatment of an artery that is 97% blocked is much easier than treating one that has been 100% blocked for a long time. The obtuse marginal (OM) arteries sometimes referred to as lateral branches are branch coronary arteries that come off the circumflex artery.There can be one or more obtuse marginal arteries. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the . flexible tube) that is guided into the blocked artery and a tiny balloon is inflated to pry open the plaque and restore blood flow.

Treatment decisions are generally based on the severity of the blockages. stenosis greater than 30% in the left main coronary artery. The first obtuse marginal artery (OM1) is usually found on or close to the obtuse margin of the heart and is also known as the .

"Widow maker" refers to a blockage in the left descending artery, which comes down the front of the heart to supply blood to the front and bottom of the left side of the heart, according to Cleveland Clinic. The branch angle between left anterior descending artery (LAD) and LCX was shallow, therefore stent implantation seemed at risk of "carina shift" of plaque to the LAD ostium as well as higher . Anand Gnanaraj, Interventional Cardiologist, Apollo Hospitals, Chennai A long standing, 100% blocked coronary artery is called a CTO (Chronic Total Occlusion). Right coronary artery (RCA) supplies blood to the left ventricle and to the right ventricle. Treatment options for LMCA disease. Symptoms include chest pain or discomfort and shortness of breath. After a normal head CT and discussion with the on-call interventional cardiologist, the patient is taken for percutaneous coronary intervention (PCI) where a 99% occlusion of the proximal left circumflex (LCX) is found and thought to be the culprit lesion (Figure 2). Identifying the presence of an anomalous coronary is quite easy when there is no severe stenosis. As the blockage worsens, symptoms typically develop. Blockage of these arteries is a common cause of angina, heart disease, heart . At 3rd year, the mortality rate for patients with significant LMS stenosis treated medically is 50%.

Delayed treatment for a heart attack can lead to significant tissue damage and scarring. The artery travels in the left atrioventricular groove between the left ventricle and left atrium.

The left coronary artery splits in two to form the left anterior descending artery (LAD) and the circumflex artery. Figure 3. (LAD) is totally or almost completely blocked. Compared to occlusions of other major coronary arteries, patients presenting with acute left circumflex (LCx) occlusion usually have ST-segment elevation on the electrocardiogram <50% of the time, potentially delaying treatment and resulting in worse outcomes. Figure 1. The prevalence of anomalous circumflex coronary arteries is rare. Treatment of an artery that is 97% blocked is much easier than treating one that has been 100% blocked for a .

It is now 90% for the right main and 90% for the left anterior descending, with the same amount on a smaller vessel called the proximal diagonal (left side). It generally supplies the lateral wall of the left ventricle and part of the posterior wall. Once pierced, the entire vessel can sometimes just tear open and this will be game over. Background Minimally invasive bypass surgery and coronary-artery stenting are both accepted treatments for isolated stenosis of the proximal left anterior descending coronary artery.
