What is proximal and mid LAD?
The LAD is made up of a proximal segment, middle segment, and distal segment. The proximal segment contains the first branch of the septal perforator. The middle segment is bordered by the first septal branch and represents the halfway point between the septal branch and the ventricular apex.
What does proximal LAD mean?
Proximal LAD was defined according to the Coronary Artery Surgery Study classification (9): end of left main to the first large septal or first diagonal, whichever is most proximal.
What is PCI to LAD in medical terms?
Percutaneous Coronary Intervention (PCI, formerly known as angioplasty with stent) is a non-surgical procedure that uses a catheter (a thin flexible tube) to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup, a condition known as atherosclerosis.
Is mid LAD blockage serious?
The total blockage of the LAD artery is a serious problem that requires immediate treatment. Delayed treatment for a heart attack can lead to significant tissue damage and scarring. It can be life threatening or lead to permanent disability.
Can the proximal LAD be stented?
Proximal LAD sirolimus-stented patients demonstrated a similar trend, with a 50% reduction in this combined end point of all-cause death, myocardial infarction, and TLR (MACE) compared with control patients (10.4% versus 20.6%, P=NS).
What is the mid LAD artery?
The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex. The LAD gives two sets of branches.
What is an LAD?
The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex.
What happens if LAD is blocked?
The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. 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 heart to stop beating normally.
Where is the proximal LAD in the heart?
The proximal LAD was defined as the vessel between the circumflex takeoff and the first major septal or diagonal branch.
