Left anterior descending (LAD)


The left anterior descending coronary artery (a.k.a. LAD, interventricular artery or the “widow maker”) supplies the anterior, anterolateral, anteroapical and apical segments of the left ventricular myocardium.

There are many coronary anomalies that can affect the LAD and many normal anatomical variants, including the presence of a dual LAD system.

Bridging of the LAD can occur and in a large majority of cases has no clinical significance.
