Types of LAD

Types of LAD

Left anterior descending coronary artery, known in short as LAD has been classified into four types depending on the length:

Type 1: Does not supply the left ventricular apex.

Type 2: Supplies part of the apex, the rest being supplied by the right coronary artery.

Type 3: Supplies the entire apex.

Type 4: Supplies the apex and more than 25% of the inferior wall (wrap around LAD).
