It is effective in modifying undilatable and uncrossable lesions, facilitating subsequent balloon angioplasty and stent deployment. Atherectomy is a valuable adjunctive therapy for patients with coronary artery disease, particularly those with severely calcified lesions where traditional balloon angioplasty and stenting may be insufficient. Its ...
Balloon angioplasty is the inflation of a balloon (often part of an integrated medical device combining a balloon, guidewire, and stent) within the coronary artery to 'crush' the plaque causing the occlusion into the walls of the artery. Balloon angioplasty is still often performed as a part of PCI procedure, it is rarely the only activity ...
From the time of the initial percutaneous balloon angioplasty, it was theorized that devices could be placed inside the arteries as scaffolds to keep them open after a successful balloon angioplasty. [14] This did not become a reality in the cardiac realm until the first intracoronary stents were successfully deployed in coronary arteries in 1986.
Since the later 1990s, most angioplasties also involve a stent over the angioplasty balloon; the balloon is hydraulically expanded, typically at 6–25 atmospheres of internal pressure, then deflated and removed while the stent remains behind to mechanically support the lumen remaining in the new, more open shape as created by the hydraulically ...
3D Medical Animation still shot of Percutaneous coronary intervention the use of angioplasty for the treatment of obstruction of coronary arteries as a result of coronary artery disease. A deflated balloon catheter is advanced into the obstructed artery and inflated to relieve the narrowing; certain devices such as coronary stents can be ...
For coronary artery disease (ischemic heart disease), coronary artery bypass surgery and percutaneous coronary intervention (coronary balloon angioplasty) are the two primary means of revascularization. [2] When those cannot be done, transmyocardial revascularization or percutaneous myocardial revascularization, done with a laser, may be an option.
