Chronic Total Occlusion Percutaneous Coronary Intervention (CTO PCI)
A manifestation of the advancements in the field of medical science lies in the introduction and development of a new unconventional approach to treat patients with Chronic Total Occlusion(CTO). Patients diagnosed with CTO, which blocks their arteries completely, can now be treated using CTO PCI which is a minimally invasive technique.
About CTO PCI
Fatty deposits or plaque when accumulated within the arteries(atherosclerosis) can result in a complete blockage and is one of the complications of Coronary Artery Disease(CAD). These blockages, when found typicallypresent for more than three months, are referred to as Chronic Total Occlusion or CTO. Due to this artery blockage, there is insufficient blood flow to heart which can cause chest pain (angina), breathlessness or a heart attack. These symptoms occur with physical strain and sometimes even at rest.
Individuals with CTOs may experience the following symptoms:
- Chest pain, pressure or tightness (angina pectoris)
- Pain in the upper body and arm
- Rapid or irregular heartbeat
Fortis Escorts is one of the few centres in India with appropriate expertise to use a combination of antegrade (forward-moving including dissection/re-entry) and retrograde (backward-moving) approaches to invade the blockage.When a blockage occurs, new blood vessels known as collateral blood vessels are formed around the blockage to assist in blood flow. Using advanced guide wires, our doctors insert a catheter into these collateral vessels, thus invading the blocked artery from multiple sides. Using a method called balloon-angioplasty which makes use of uninflated balloon placed at the tip of the catheter and later inflated while in the artery, the opening in the arteries are dilated to restore the blood flow.
CTO PCI is a complex and intricate procedure performed by Fortis Escorts’ well-experienced physicians. The team here carries out a complete assessment in conjunction with the primary care team to formulate an individually directed, comprehensive treatment plan. Traditionally, for treating these blockages, open-heart surgery was recommended as a sole option. However, advanced techniques have paved the way for treating CTO with minimally invasive methods wherein success rate of greater than 90%.
Due to the complexity and the risk involved in the procedure, CTO PCI should be performed only by experienced medical experts who have been trained and specialized in treating CTO blockages. The duration of the procedure may vary from two to three hours depending on the severity of the blockages. All the patients are kept under observation and are monitored in the hospital overnight after the procedure.
What are the risks of the procedure?
Though most of the perils are almost similar to those for routine angioplasty, the CTO PCI procedure involves an added risk of bleeding at the entry site into arteries in the groin. Other risks include sudden closure of the coronary artery, small tear in the inner lining of the artery, heart attack.
With the experience and commitment of the team of experts who have been long researching on the advanced methods to treat CTO, the future of CTO treatment looks promising. At Fortis Escorts, the CTO PCI is performed by Dr. Arun Kalyanasundaram, Director CTO program and the team of CAD includes experts who determine the best course of treatment for CTO. Fortis Escorts’ reputationthroughout the years is based on the commitment to ensure patients’ safety and recovery while pivoting on the trust bestowed by people and its leading research and dedication to excel.
