The patient presents to the ED with severe chest discomfort. A cardiac catheterization and angiography shows an 90% occlusion of the left main coronary artery. Which procedure will be most likely performed on this patient?
Coronary artery bypass graft surgery
Radiofrequency catheter ablation
Implantable cardioverter-defibrillator placement
Circulatory assist device
The Correct Answer is A
A. Coronary artery bypass graft (CABG) surgery is typically recommended for patients with significant occlusion of the left main coronary artery, as it effectively restores blood flow to the heart muscle by bypassing the blocked artery.
B. Radiofrequency catheter ablation is used to treat arrhythmias, not coronary artery occlusions.
C. Implantable cardioverter-defibrillator (ICD) placement is for managing life-threatening arrhythmias, not directly for treating coronary artery blockages.
D. A circulatory assist device is used in severe cases of heart failure, but it does not address the underlying issue of coronary artery occlusion.
