What does ostial RCA mean?
Ostial lesion was defined as a proximally significant stenosis up to 3 mm from the coronary origin. Nonostial lesion was considered as a distally significant stenosis up to 3 mm from the coronary origin.
What does PCI to RCA mean?
Percutaneous coronary intervention (PCI) for anomalous right coronary artery (RCA) arising from the left sinus of Valsalva (LSOV) is a technical challenge due to inadequate guiding catheter support to overcome the acute rightward course of the anomalous RCA.
What is RCA stent?
A coronary artery stent is a small, metal mesh tube that expands inside a coronary artery. A stent is often placed during or immediately after angioplasty. It helps prevent the artery from closing up again. A drug-eluting stent has medicine embedded in it that helps prevent the artery from closing in the long term.
Where is the ostial RCA?
The ostia of the left and right coronary arteries are located just above the aortic valve, as are the left and right sinuses of Valsalva.
What causes ostial stenosis?
While most commonly due to atherosclerosis, it may also be caused by aortic arteritis, congenital webs or post-surgical complications following aortic valve replacement. Three cases of lethal ischemic heart disease are reported where occult ostial narrowing/occlusion was first identified at autopsy.
What is heart ostial?
In human cardiovascular system: Blood supply to the heart. The ostium, or opening, of the right coronary artery is in the right aortic sinus and that of the left coronary artery is in the left aortic sinus, just above the aortic valve ring.
Does PCI mean stent?
Percutaneous Coronary Intervention (PCI, formerly known as angioplasty with stent) is a non-surgical procedure that uses a catheter (a thin flexible tube) to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup, a condition known as atherosclerosis.
Does PCI always involve stenting?
Today, PCI usually includes the insertion of stents, such as bare-metal stents, drug-eluting stents, and fully resorbable vascular scaffolds (or naturally dissolving stents). The use of stents has been shown to be important during the first three months after PCI; after that, the artery can remain open on its own.
Can RCA be stented?
Stenting was performed on the RCA lesion. Immediately after undergoing those interventions, thrombosis developed and occluded SN artery.
What is LAD and RCA in heart?
The left anterior descending artery gives off the diagonal branches. The RCA supplies blood to the right side of the heart. The sinoatrial nodal branch of the RCA provides blood to the SA node, and the atrioventricular nodal artery delivers blood to the AV node.
What does ostial mean in medicine?
: a mouthlike opening in a bodily part (such as a fallopian tube or a blood vessel)
What does the RCA do?
Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm.
Can stent-less PCI be used for calcified RCA ostial lesions under IVUS?
The both cases suggest that stent-less PCI using RA/DCB under IVUS might be an alternative revascularization therapy of choice for calcified RCA ostial lesions. The both cases suggest that stent-less PCI using RA/DCB under IVUS might be an alternative revascularization therapy of choice for calcified RCA ostial lesions.
Is there an alternative revascularization therapy for calcified RCA ostial lesions?
The both cases suggest that stent-less PCI using RA/DCB under IVUS might be an alternative revascularization therapy of choice for calcified RCA ostial lesions. Potent Stent-Less Procedure Using Rotational Atherectomy and Drug-Coated Balloon to Right Coronary Ostial Lesion
What are coronary stents used for?
Coronary stents play a vital role in the management of acute occlusive coronary artery disease. Stents have increased the safety and revascularization success rate which led to the improvement in clinical outcomes ultimately.[1]
What is the diameter of a stent for an ostium?
The lesion was dilated with a 3.0 mm diameter by 20 mm long compliant balloon and a 3.5 mm diameter by 23 mm long sirolimus-eluting stent positioned to cover the ostium ( Figure 10-4 and Video 10-3) and postdilated with a 4.0 mm diameter by 9 mm long noncompliant balloon to high pressures.
