What is subintimal angioplasty?
Subintimal angioplasty is a minimally invasive percutaneous technique for the recanalization of occluded lower limb arteries (London 1993; Nydahl 1997). Subintimal angioplasty was first described in 1990 to overcome long and chronic arterial occlusions (Bolia 1990).
What is subintimal dissection?
Subintimal dissection/reentry techniques are increasingly being used for crossing coronary chronic total occlusions both antegradely (using a knucle wire or the Bridgepoint system) or retrogradely (using the controlled antegrade and retrograde tracking and dissection, and reverse controlled antegrade and retrograde …
What is CTO angioplasty?
Chronic Total Occlusion Angioplasty Chronic Total Occlusion (CTO) is build-up of complex total blockage with fatty deposits inside the walls of coronary artery for more than 3 months.
What is the subintimal space?
Subintimal space in CTO PCI. Historically the subintmal space, which lies between the intima and adventitia, has been feared by coronary interventionalists with the notion that the coronary wire should be steered within the true lumen along the length of a stenosis or occlusion.
What is J CTO score?
9–11 The multicenter Japanese CTO Registry12 investigators developed the J-CTO score as a scoring system to grade the difficulty in crossing a CTO within 30 min- utes and overall success rate.
What is reverse CART technique?
In the CART/reverse-CART techniques, antegrade and retrograde wires are placed into the subintimal plane of a CTO. A balloon is placed and inflated from either an antegrade or retrograde approach into the subintimal space of the occlusion.
What does CTO of RCA mean?
CTO: Chronic total occlusion; RCA: Right coronary artery; LAD: Left anterior descending; LCA: Left circumflex artery; PCI: Percutaneous coronary intervention; CABG: Coronary artery bypass graft.
What is CTO of RCA?
Coronary chronic total occlusion (CTO) is a distinct subset of coronary artery disease (CAD) and it is defined as a coronary artery with absent anterograde blood flow for more than 3 months.
Is ballooning same as angioplasty?
The angioplasty stenting procedure uses a small stent to help support your coronary artery. The balloon catheter is used to place the stent into the clogged coronary artery. The balloon is then inflated, which causes the stent to expand in size.
What is the difference between ballooning and stent?
Balloon angioplasty is a minimally invasive cardiac catheterization procedure used to open narrow and blocked arteries. Heart stents are tiny lattice-shaped metal tubes that serve as scaffolding to keep the artery open.
