Chronic Total Occlusion PCI

A Chronic Total Occlusion Percutaneous Coronary Intervention is done to clear blockages that have been present for more than 3 months, often a result of atherosclerosis. It is done in the case of completely blocked arteries and the duration of the procedure varies from patient to patient. This requires a greater expertise as the doctor uses both antegrade and retrograde approaches to reach to the blockage. After identifying the blockage, the expert cardiologist would insert catheter into the collateral vessels for entering the blocked artery. An inflated balloon then gets placed and blown up at the tip of the catheter facilitating a wide opening of the arteries for restoring blood flow and also place a stent.
