We present a case of left main spasm which was associated with spasm of a saphenous vein graft. This case emphasizes the importance of excluding an excessive vasoconstrictory response in patients treated with percutaneous coronary interventions. (c) 2004 Elsevier Ireland Ltd. All rights reserved.

Assessment of myocardial "blush" by either Myocardial Blush Grade or TIMI Myocardial Perfusion Grade, is the angiographic method currently preferred to confirm myocardial tissue-level perfusion after primary percutaneous intervention. This review focuses on the utility of angiographic "blush" as a simple, widely available, and virtually...

Six consecutive patients (3 men; mean age, 63 +/- 14 years; age range, 38-81 years) with infrarenal abdominal aortic stenosis underwent unilateral or bilateral transradial approach for stenting of the aortic lesion. In 4 cases, isolated aortic stenting was performed through single transradial approach (in 2 cases with precise alignment to the...

Aims: Microvascular obstruction (MVO) is associated with a worse prognosis in patients with ST-elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI). However, data about incidence, clinical outcome and correlates of MVO in latecomers after STEMI are still lacking. Methods: We prospectively enrolled...

This study was performed to analyze the impact of transradial intervention (TRI), performed by long (25-cm) hydrophilic-coated radial introducer sheath (HRS), on radial artery (RA). Both acute damages and chronic intimal modifications, occurring in RA, were assessed using frequency domain-optical coherence tomography (FD-OCT). FD-OCT evaluation...

Background: Peripheral arterial disease is a risk factor for cardiac mortality but pathophysiologic mechanisms linking atherosclerosis of peripheral arteries with coronary events in the single patient have not been established. Method and results: We evaluated by frequency-domain optical coherence tomography (FD-OCT) the possible association...

The efficacy of DEB in modifying the high restenosis risk associated with BMS implantation is doubtful. Optical coherence tomography (OCT) may allow precise assessment of neointimal formation after stent implantation. We performed a single-center, prospective, 1:2 randomized trial comparing BMS implantation alone (BMS group) vs. additional DEB...

Background: Endothelialisation is a crucial event after percutaneous coronary intervention (PCI). Endothelial progenitor cells (EPCs) are bone marrow derived elements with reparative properties. We aimed to assess the relationship between circulating EPC levels and stent neointimal hyperplasia (NIH) using frequency domain optical coherence...

Background. The use of thrombus aspiration during percutaneous coronary intervention (PCI) is recommended in patients with ST-elevation myocardial infarction (STEMI) undergoing mechanical revascularization. When thrombus aspiration is adopted, the standard technique includes, after mechanical thrombus extraction, angioplasty and/or stem...

Background The cause for discrepancy in the clinical presentation and outcome of coronary artery disease ( CAD) between men and women is not established. Different prevalences of risk factors or specific sex-related atherosclerotic aspects have been advocated as possible explanations. We investigated coronary plaque morphology looking at...
