However, we thought that a 4.2 Fr diagnostic catheter could not be controlled enough to engage the left coronary artery due to the unfavorable shape of the 5 Fr guiding catheter tip. (hindawi.com)
Then, alternate manipulation of the DIO thrombus aspiration catheter and the angiographic catheter was very effective in advancing the two catheters through the artificial aorta, allowing these two catheters to be inserted into the left coronary artery. (hindawi.com)

The extent of coronary collateral vessels and their significance are controversial issues. (elsevierpure.com)
abstract = "The extent of coronary collateral vessels and their significance are controversial issues.1 The controversy regarding collaterals in man is related, to a large extent, to the lack of an appropriate method to assess collateral function in vivo. (elsevierpure.com)

Beating heart multi-vessel minimally invasive direct coronary artery bypass grafting: techniques and pitfalls. (ottawaheart.ca)

Among these apparatus and techniques are balloon dilitation and plaque excision. (justia.com)
Among known balloon dilitation devices are coronary, peripheral vessel, bile duct and thorasic catheters. (justia.com)

new techniques in CTO - Angio and IVUS based 3D wiring. (terumo-europe.com)
Intravascular ultrasound (IVUS) represents a powerful imaging technique to explore coronary vessels and to study their morphology and histologic properties. (uab.es)
Deterministic approaches fail to yield optimal results due to the large amount of IVUS artifacts and vessel borders descriptors. (uab.es)
This has encouraged development of IVUS motion compensation techniques. (uab.es)

In addition, the Onyx Frontier™ zotarolimus-eluting coronary stent system is indicated for treating de novo chronic total occlusions and non-left main bifurcation lesions utilizing the provisional bifurcation stenting technique. (medtronic.com)
This suggests that although measurements of coronary flow reserve (CFR) and fractional flow reserve (FFR), both of which are discussed below, may be useful in the assessment of the severity of stenoses and in the identification of lesions responsible for effort angina, they are not likely to identify the more dangerous plaques responsible for unstable angina, AMI, and sudden ischemic death.

Patient position and skin incision were the same as for minimally invasive isolated coronary artery bypass grafting. (ctsnet.org)
The most appropriate of these techniques for each patient may depend on characteristics of both the patient and their diseased artery, Hahn said. (dicardiology.com)
For example, endovascular techniques mastered within the small- caliber and bifurcating coronary artery vessels of a beating heart in a conscious patient can be applied in larger vessels within immobile organs, especially when procedures are done under sedation or anesthesia. (ama-assn.org)

There are invasive and non-invasive techniques exploring various aspects of pathobiology (3). (escardio.org)
The invasive technique involves delivery of vasoactive agents via intra-arterial infusion. (escardio.org)
Moreoever, this technique is invasive and costly, therefore, wide spread use and clinical utility is limited. (escardio.org)
This measurement is called fractional flow reserve (FFR), and this diagnostic technique previously required an invasive procedure called cardiac catheterization. (geisinger.org)
Sometimes coronary bypass surgery can be performed with minimally invasive techniques, making only small incisions in the chest, resulting in less risk and trauma and faster recovery. (atlantichealth.org)

Numerous methods for evaluating the peripheral arterial system have emerged as alternatives to coronary endothelial function testing. (escardio.org)

Stenting of coronary bifurcations carries higher risk for in-stent restenosis, stent thrombosis, and recurrent clinical events. (elsevierpure.com)

New cardiac CT techniques can assess coronary artery inflammation by imaging perivascular fat, and this may represent an important step forward in identifying the 'residual risk' that is not detected by plaque or ischaemia imaging. (bmj.com)

[ 4 ] Three years later René Favoloro performed the first successful coronary bypass operation using the saphenous vein. (medscape.com)
