Wiring through stent struts into a jailed side branch can be challenging. We describe a case of double-barrel left main coronary artery stenting into the first obtuse marginal branch that resulted in significant ostial circumflex coronary artery stenosis. We were unable to wire the jailed large distal circumflex artery. We introduced the Twin-Pass catheter over the first obtuse marginal wire, p...

We describe two cases with iatrogenic left main coronary artery stenosis where a symptomatology of unstable angina appeared within three months of aortic valve replacement surgery. One patient was treated with aortocoronary bypass and the other with angioplasty and stenting.

Iatrogenic aortocoronary dissection is a rare but potentially disastrous complication of percutaneous coronary intervention. The left main dissection extending into distal bifurcation involving both the left anterior descending and left circumflex is a complex and vital complication, which is classified as Eshtehardi Type II dissection. We presented a case of iatrogenic left main coronary arter...

Unprotected left main coronary artery (ULMCA) lesions are candidates for coronary artery bypass surgery because of the high risk of serious adverse periprocedural events and long-term complications associated with percutaneous coronary intervention (PCI). Although coronary stents have improved initial outcomes of PCI with coronary balloon angioplasty, the outcomes of coronary stenting in ULMCA ...

Coronary atherectomy and coronary stenting effectively reduce the severity of coronary artery stenoses, but direct comparisons of these interventions with conventional balloon angioplasty have not been performed. To compare the immediate efficacy of these 3 interventions, the angiographic morphology and the severity of the residual coronary stenosis were quantitatively evaluated in 18 patients ...

To determine the feasibility and safety of development of this new stent, we deployed 28 AVE Micro stents in 23 native coronary artery lesions in 20 patients who developed acute or threatened closure after balloon angioplasty (BA). Ten stents were deployed in the left anterior descending artery, 10 in the circumflex, and 8 in the right coronary artery. Luminal dimensions were measured using a c...

OBJECTIVES: To compare coronary artery bypass to stenting in our institution, and to compare the studied samples for major adverse cardiac and cerebrovascular outcomes. METHOD: An observational cohort study. We analyzed 202 patients undergoing coronary artery surgical revascularization versus stenting in our institution between January 17 and July 31, 2009; patients were stratified into: Group ...

Treatment with oral anti-platelet agents constitutes a cornerstone in the therapy of coronary artery disease. Coronary angioplasty and stent implantation improved the therapy of coronary artery disease and especially the treatment of acute myocardial infarction. Implementation of glycoprotein IIb/IIIa inhibition further advanced anti-platelet therapy as a central component in the treatment of a...

BACKGROUND Percutaneous coronary intervention with stenting in patients with coronary atheromatous stenosis carry an inherent risk of affecting the baroreflex-mediated regulation of hemodynamic alterations, especially for heart rate and blood pressure. To the best of our knowledge, the vagal baroreflex activation associated with acute coronary stent thrombosis in patients who have undergone per...

OBJECTIVE To describe the long term clinical outcome (up to 11 years) after coronary stenting. DESIGN A single centre observational study encompassing 1000 consecutive patients with a first stent implantation (1560 stents) between 1986 and 1996, who were followed for at least one year with a median follow up of 29 months (range 12-132 months). RESULTS Up to July 1997 the cumulative incidenc...
