Coronary artery disease can be treated with
percutaneous coronary intervention (also known as PCI, angioplasty or coronary stenting). A narrowing of a heart artery (coronary artery disease) can reduce the flow of blood to the heart muscle causing angina (chest pain). If the there is sudden blockage of a heart artery then his causes a heart attack. PCI can be used to treat these coronary artery problems with thin tubes, wires, small balloons and stents to restore the blood flow to the affected area of the heart. If the disease involves a point where the artery divides into two or more branches, specific 'bifurcation' techniques can be used to insert more than one stent to treat the diseased area.
Coronary stenting can be guided and optimised by the use of a
pressure wire study (an accurate assessment of coronary blood flow) and/or
intravascular imaging to look at the arteries with thin ultrasound and light telescopes (eg IVUS or OCT).
During angioplasty other complex adjuvant techniques can be used, such as Rotational Atherectomy or intra-vascular lithotripsy, to help modify tough calcified material in the artery.
