If, based on the result of probing the heart, i.e. selective coronary angiography (SCG), it is determined that the coronary arteries have suffered major damage, leading to s decrease in their diameter and a deterioration of the blood supply to the heart, it is possible to follow up with the treatment procedure via the probe.
In case of technical compatibility, it is possible to widen the coronary artery. This procedure is called percutaneous coronary intervention (PCI). As a result of PCI, the coronary artery is usually fitted with a stent, which is a tubular mesh detail to support the expanded part of the blood vessel.
