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…
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…
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…
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…
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…
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…
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…
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…
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,…
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…
