Large (approximately 3 x 4 cm) pseudoaneurysm seen in the right anterior oblique projection (arrows).
Spontaneous Closure of a Perforation-Induced Coronary Artery Pseudoaneurysm
CATHETER TECHNIQUES FOR THE TREATMENT OF ANEURYSMS
Coronary artery perforation is a rare but potentially fatal complication of percutaneous coronary interventions.1,2 Most cases are recognized at the time of the procedure. While some are identified as a localized collection of contrast outside the ar…
Initial coronary angiography. Severe focal stenosis after major septal branch.
Rapid Evolution from Coronary Dissection to Pseudoaneurysm After Stent Implantation: A Glimpse at the Pathogenesis Using Intrava
Coronary dissection during percutaneous coronary intervention (PCI) occurs frequently and is associated with variable evolution, including the development of acute closure with serious clinical consequences. Stent sealing of the false lumen is a comm…
A) Coronary angiogram before angioplasty. A long stenotic lesion of the mid-right coronary artery (arrow) and a more proximal mildly stenotic curvature with calcification (arrowhead) can be seen. The former was the target of intervention. (B) Coronary ang
Aortic Dissection Complicating Failed Coronary Stenting
Coronary dissection is a well-known complication of coronary interventions; however, proximal progression of the dissection into the aortic root happens rarely.1 The outcome and therapeutic strategy for this iatrogenic complication need to be establi…
Angiogram showing an aneurysm of the distal right internal carotid artery. Successful deployment of a stent graft (Wallgraft) completely obliterated the aneurysm.
Endovascular Treatment of Carotid Artery Aneurysms with Stent Grafts
Aneurysms of the carotid arteries is a rare but well described entity. Cervical carotid artery aneurysms can cause cerebral embolism and transient ischemic attacks.1 Surgery, however, is often difficult because of the location and the damaged arteria…
LETTER TO THE EDITOR:
Letting the Air out of the Follow-up Balloon
To the Editor: We’ve read the editorial comment1 made by Dr. Turi on our study “Percutaneous Mitral Valvotomy: Six Year Follow-up”.2 Although we thank Dr. Turi for his insights, we disagree profoundly with the core of his criticism concerning lack o…
Part II: Risk Stratification in Patients with Unstable Angina and Non-ST Segment Elevation Myocardial Infarction: Evidence-Based
In last month’s issue of the Journal, we published Part I of this article. This month’s conclusion focuses on other risk stratification models and tools. Several major studies have established the benefit of glycoprotein (GP) IIb/IIIa inhibitors in…
Clopidogrel Treatment Before Percutaneous
Coronary Intervention Reduces Adverse Cardiac Events
The benefit of platelet inhibition during percutaneous coronary intervention (PCI) has been known for some time.1 In recent years, the interest has focused on the platelet glycoprotein IIb/IIIa inhibitors, which block the final common pathway of plat…
Angiogram performed twelve hours later showing complete exclusion of the CAA and total occlusion of the PDA branch.
Treatment of a Giant Coronary Aneurysm with a Novel Technique: Scaffolding (Tunnel) Stenting to Support PTFE-Covered Stents: Ins
Coronary artery aneurysm (CAA) is an uncommon condition with a natural history and prognosis still obscure.1 Aneurysmal coronary artery disease is defined as coronary dilatation that exceeds the diameter of the adjacent reference vessel by 1.5 times…
Left subclavian angiogram demonstrating the location of the pseudoaneurysm distal to the origin of the left internal mammary artery and the vertebral artery.
Subclavian Artery Pseudoaneurysm: Successful Exclusion with a Covered Self-Expanding Stent
CATHETER TECHNIQUES FOR THE TREATME
Pseudoaneurysms are encapsulated hematomas that communicate with an artery because of an incomplete seal by the media. Although femoral artery pseudo-aneurysms occurring as a complication of cardiac catheterization are familiar to an interventionist,…
Coronary angiogram shows a normal RCA and a saccular aneurysm of the LMCA with < 50% luminal narrowing at the origin of the circumflex artery.
Obliteration of a Left Main Coronary Artery Aneurysm with a PTFE-Covered Stent
CATHETER TECHNIQUES FOR THE TREATMENT OF ANEURY
There are many reports in the literature about coronary artery aneurysms, their incidence, pathogenesis, clinical outcome and treatment.1–3 If asymptomatic, their progression, rupture or secondary embolization are unpredictable. Some aneurysms are re…
