PCI is considered 'non-surgical' as it uses a small hole in a peripheral artery (leg/arm) to gain access to the arterial system; an equivalent surgical procedure would involve the opening of the chest wall to gain access to the heart area. The term 'coronary angioplasty with stent' is synonymous with PCI.
A 2015 trial compared CABG and the latest technological advancement of PCI, second-generation drug-eluting stents in multivessel disease. Their results indicated that CABG is a better option for CAD patients. [17] A trial published in 2021, comparing results after one year, also concluded that CABG is a safer option than PCI. [18]
A PCI involves performing a coronary angiogram to determine the location of the infarcting vessel, followed by balloon angioplasty (and frequently deployment of an intracoronary stent) of the stenosed arterial segment. In some settings, an extraction catheter may be used to attempt to aspirate (remove) the thrombus prior to balloon angioplasty.
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 ...
During a protected percutaneous coronary intervention (Protected PCI) procedure, "the Impella 2.5 heart pump helps maintain a stable heart function by pumping blood for the heart. This gives a weak heart muscle an opportunity to rest and reduces the heart’s workload, preventing the heart from being overstressed by the procedure as coronary ...
The range of lumen stenosis locations at which myocardial infarctions occurred ranged from areas of mild dilation all the way to areas of greater than 95% stenosis. However the average or typical stenosis at which myocardial infarctions occurred were found to be less than 50%, [ 8 ] describing plaques long considered insignificant by many.
Often, a stent is used, and as the balloon is inflated, the stent in place expands and holds open the artery. The balloon is then deflated and removed, leaving the stent in place. After the completion of the procedure, the catheter is removed, and the plug area is sealed using angio-seal.
[5] [6] The physiologist will also set up a temporary pacemaker if the procedure is an angioplasty or a percutaneous coronary intervention (PCI). Finally, they also set up defibrillators on to the patient for emergency use if needed. In some locations, some of these responsibilities may be carried out by other personnel, such as trained nurses ...
