Salam Left main coronary artery (LMCA) stenosis involving a trifurcation is a particularly complex anatomical and clinical challenge. Here's a breakdown of the condition and the TAP approach used to manage it: --- *🫀 What Is Left Main Trifurcation Stenosis?* - *Anatomy*: Normally, the LMCA bifurcates into the left anterior descending (LAD) and left circumflex (LCx) arteries. In about 10–15% of cases, it trifurcates, adding a third branch—often a ramus intermedius⁽¹⁾⁽²⁾. - *Clinical Significance
