PCI is widely practiced and has a number of risks; [9] however, major procedural complications are uncommon. PCI is performed using minimally invasive catheter-based procedures by an interventional cardiologist, a medical doctor with special training in the treatment of the heart. [10]
In the blood supply of the heart, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. [ 1 ] [ 2 ] It travels down the right coronary sulcus , towards the crux of the heart .
The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES). They are used in a medical procedure called percutaneous coronary intervention (PCI). Coronary stents are divided into two broad types: drug-eluting and bare metal stents. As of 2023, drug-eluting stents were used in more than 90% of all PCI ...
The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...
Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Andreas Gruentzig is considered the father of interventional cardiology after the development of angioplasty by interventional radiologist Charles Dotter .
If PCI failed to restore blood flow because of anatomical considerations or other technical problems, urgent CABG is indicated to save heart tissue. The timing of the operation plays a role in survival: It is preferable to delay the surgery if possible (three days if the infarction affecting the total thickness of the cardiac muscle, and six ...
PCI involves placing a stent to relieve coronary artery blockages. [12] CABG involves grafting new blood vessels to provide a new route for blood flow around the blocked vessel. [12] Choice of treatment is based on the number of coronary vessels with blockages, which vessels are effected, and the medical history of the patient. [37]
The right coronary artery (RCA) originates within the right cusp of the aortic valve. It travels down the right coronary sulcus, towards the crux of the heart. The RCA primarily branches into the right marginal arteries, and, in 67% of individuals, gives place to the posterior descending artery. [4]
