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…
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…
The term acute coronary syndromes (ACS) comprise a continuum of diseases of various risks and severities including unstable angina pectoris, non-Q and Q-wave myocardial infarction (MI) and sudden death.1 These conditions share a similar pathologic pa…
Coronary stenting has evolved into the principal non-balloon device in percutaneous coronary intervention (PCI) procedures.(1) Continual improvement in stent designs promises greater deliverability and durability. Indeed, widespread application of th…
Coronary stenting is generally associated with lower rates of restenosis than balloon angioplasty.1,2 However, in-stent restenosis (ISR) remains a significant clinical problem.(3) Pharmacological inhibition of ISR has shown potential in laboratory an…
