CTO treatment is performed to open completely blocked coronary arteries that obstruct blood flow to the heart muscle. This procedure is carried out by specially trained interventional cardiologists, in modern catheter laboratories and under local anaesthesia. During the procedure, the patient is monitored and their vital signs are continuously tracked.

The treatment process begins by accessing the blocked vessel through a catheter inserted in the groin or wrist. Advanced imaging techniques are used to determine the structure of the vessel, and an appropriate treatment strategy is selected. Special microcatheters and guide wires are used to open the blockage, and balloon angioplasty is performed.

In experienced centres, the success rate of the procedure is around 85-90%. Patients are kept under observation for 48 hours after the procedure. Most patients can return to their daily activities within a week, but should avoid strenuous exercise for a month. A control angiography is performed 6-12 months later.
