LAD-diagonal bifurcation
The branching point where a diagonal branch arises from the left anterior descending coronary artery.
Full Definition
The LAD-diagonal bifurcation refers to the anatomical point where a diagonal branch vessel originates from the left anterior descending coronary artery. These bifurcations are common sites of atherosclerotic disease and present unique challenges for interventional procedures due to the risk of side branch compromise. In cardiovascular radiology, proper identification and classification of these bifurcations is essential for procedural planning, as they may require specialized techniques such as provisional stenting or dedicated bifurcation stenting strategies.
Usage
Usage note: Hyphenate when describing the bifurcation point. LAD should remain capitalized.
