What is retrograde CTO?
In the retrograde approach, a guidewire is advanced through a collateral channel into the distal true lumen, followed by CTO crossing using various techniques.
What does retrograde approach mean?
The attempt of the retrograde approach was defined as the introduction of a guidewire into the collateral channels, which connecting with the target coronary artery distal to the target CTO lesion.
What is retrograde angioplasty?
The retrograde procedure consists of cannulating the 2 coronary ostia and advancing a guidewire from the unoccluded artery to the region distal to the occlusion via collaterals originating from the healthy artery.
What does CTO PCI mean?
CTO PCI is a minimally invasive technique used to treat patients with chronic total occlusion (CTO), or complete blockages, of the coronary arteries.
What is cart in cardiology?
Predicts risk of in-hospital cardiac arrest.
What is CART technique?
The CART technique involves dilation of a balloon over the retrograde wire and antegrade wiring. The reverse CART involves dilation of a balloon over the antegrade wire and retrograde wiring.
What is reverse cart?
In traditional reverse CART, we overlap antegrade and retrograde wires and inflate the antegrade balloon and try to puncture into the antegrade balloon space from the side of the balloon (side balloon entry technique). However, sometimes the wire would slip up parallel to the balloon instead of puncturing in.
What is CTO disease?
Chronic total occlusion (CTO) is a complete or nearly complete blockage of one or more coronary arteries. The blockage, typically present for at least three months, is caused by a buildup of plaque within a coronary artery. When this happens, blood flow to the heart is compromised.
How is CTO PCI performed?
They use tiny wires (or catheters) and other minimally invasive tools to approach the CTO blockages. Standard PCI involves passing the wire through each blockage. But, CTO treatment involves guiding these wires and tools through microscopic layers of the arterial wall and around the blockage.
What is CART PCI?
Percutaneous coronary intervention (PCI) is a non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease.
