Panchkula June, 7: A day long cardiology workshop on chronic total occlusion (CTO) was held at Alchemist hospital on Tuesday. The workshop comprised three CTO cases, was performed by Dr Rohit Parti and Dr Arvind Kaul Cardiologist Alchemist Hospital along with their team under the supervision of Dr Gerald Werner from University of Frankfurt / Main & Heidelberg- Mannheim, Germany.
Angioplasties for chronic total occlusion were done from both antegrade and retrograde technique
Although the heart is the strongest muscle of the body, but is highly vulnerable to various unhealthy lifestyle habits. Many such habits have been the cause of some severe heart ailments resulting in total or partial occlusion of arteries. Total occlusion of arteries is usually resolved through a By-Pass surgery. It has been seen that due to the risks associated with surgery, patients are often reluctant of undergoing a by-pass surgery.
However, with the advancement of technology, a new procedure, Chronic Total Occlusion Intervention (CTO Intervention) has been invented which allows patients even with 100% one artery blockage to undergo angioplasty.
Dr Rohit Parti said that Angioplasty for CTO lesions is of immense use when patients cannot be sent for surgery due to other medical reasons or don’t fulfill the criteria to undergo CABG.
CTO Intervention is one of the latest advancements in the field of interventional cardiology and has experienced significant growth in the last few years. With the adaptation and refinement of advanced techniques, including retrograde and dissection/re-entry (Please explain), there has been a significant increase in the attempts of CTO Intervention in many countries abroad, inspiring many interventional cardiologists all over the world to explore this cutting-edge field for patient benefit. With a good success rate in India, this procedure is usually conducted on patients where only one artery is totally blocked. It is less invasive and less complicated than a by-pass surgery. The procedure can provide significant benefits to patients who have no revascularization options (i.e. patients with previous CABG who present with graft failure) or may be referred for surgery because PCI is not considered to be feasible (i.e. patients with isolated right coronary artery CTO and medically refractory angina). However, this procedure is not advised for patients of kidney failure considering the high quantity of dye used. Increasing data suggests successful CTO Intervention can alleviate angina, improve left ventricular systolic function and possibly reduce the impact of future ACS or even improve survival. Moreover, the procedure can be accomplished safely with low complication rates.
