Coronary Angiographic Morphology in Unstable Angina: Comparative Observations of Culprit Lesions in Saphenous Vein Grafts Versus

Lynn M. Preston, DO, James E. Calvin, MD, Steven Class, MD, Joseph E. Parrillo, MD, Lloyd W. Klein, MD

The acute coronary syndromes share a common pathogenetic mechanism involving plaque disruption, platelet activation and superimposed thrombus.1 Acutely ruptured plaques have a characteristic angiographic appearance directly reflecting mechanical disruption at the shoulder of the atherosclerotic plaque. Intracoronary thrombus is also commonly observed in patients with severe episodes of acute ischemia and is angiographically demonstrable with a higher incidence than in less acute presentations.2 The marked heterogeneity in patient characteristics and morphologic features directly reflects the w...

Use of a 0.014´´ Guidewire for Cannulation of Left Coronary Ostium with a Difficult Anatomy

Timur Timurkaynak, MD, Haci Ciftci, MD, Atiye Çengel, MD

Engagement of the left coronary ostium is usually accomplished with the standard Judkins technique in the majority of patients without further manipulation.1 For the minority of patients with difficult anatomies, there is an enormous variety of catheters available with different sizes and unique designs.2–6 However, catheter selection in most labs may be limited to those most frequently used (i.e., Judkins, Amplatz, Multipurpose), resulting in inadequate imaging of the coronary arteries.
We report a case with a difficult left coronary anatomy in which the left coronary ostium could not be ...

“Cutting Balloon and the Three Burrs”: Treatment for Ostial Left Anterior Descending Artery In-Stent Restenosis

Serge Osula, MBBS, MRCP and David R. Ramsdale, BSc, MBChB, FRCP, MD

In-stent restenosis (ISR) is a difficult complication to treat, occurring in 15–35% of stents deployed for de novo lesions in native coronary arteries.1,2 The restenosis rate following therapy for ISR is as high as 54%.3 Thus far, there is conflicting evidence in the literature as to the most practical approach for treating in-stent restenosis. We report a case of a left anterior descending artery (LAD) ostial in-stent restenosis treated with a combination of rotational atherectomy and “cutting” balloon percutaneous transluminal coronary angioplasty (PTCA).
