Left main coronary artery disease occurs when there is a blockage or narrowing in the main artery supplying blood to the left side of the heart. This condition is critical as it affects the blood flow to a significant portion of the heart muscle, potentially leading to severe complications such as heart attack or heart failure if left untreated.
Percutaneous coronary angioplasty, also known as balloon angioplasty, is a minimally invasive procedure used to widen narrowed or blocked arteries in the heart. When applied to the left main coronary artery disease, PTCA aims to restore blood flow to the heart muscle by opening up the obstructed artery using a balloon catheter.
PTCA in left main coronary artery disease is performed to address the critical blockage or narrowing in the main artery supplying blood to the left side of the heart.
