Comparison of detection percentage and morphology of myocardial bridge between conventional coronary angiography and coronary CT angiography.

Myocardial bridge (MB) is a congenital anomaly in which a segment of a coronary artery is surrounded by myocardium. In our study, we want to use conventional coronary angiography (CCA) to describe morphologic characteristics of MB (unidentified or identified) in the patients with documented evidence of MB in coronary computed tomography angiography (CCTA). The present study was designed as cross-sectional and was conducted on 47 patients with documented evidence of MB in CCTA, who were referred to Nemazee and Faghihi hospitals for performing coronary angiography during a one year period.

Impact of Omega-3 Supplementation on High Sensitive C-Reactive Protein Level and 30-Day Major Adverse Cardiac Events After the Implementation of Coronary Stent in Patients with Chronic Kidney Disease: A Randomized Clinical Study.

Studies have revealed that patients with chronic kidney disease (CKD) are more susceptible to adverse effects of percutaneous coronary intervention (PCI). In addition, the role of elevated high sensitive C-reactive protein (hs-CRP) in the prediction of adverse cardiac outcomes after coronary stent implantation has already been shown. Therefore, in this study, we aimed to evaluate the effect of omega-3 supplementation on hs-CRP and 30-day major adverse cardiac events (MACE) in patients with CKD undergoing elective PCI.

Endovascular Repair of the Traumatic Dissection of the Subclavian-Axillary Artery: Report of Four Cases.

Traumatic injuries to the subclavian-axillary artery, although uncommon, are associated with high morbidity and mortality rates if not managed promptly. The emergence of endovascular techniques offers an alternative to the surgical management of these injuries. We herein present 4 cases of traumatic subclavian-axillary artery injury with limb ischemia successfully managed via the endovascular approach with non-covered self-expandable stents.

Increased risk of coronary perforation during percutaneous intervention of myocardial bridge: What histopathology says.

Myocardial bridge (MB) is a segment of a major epicardial coronary artery that goes intramurally under a bridge of overlying myocardium.

Background: Percutaneous coronary intervention provides a high-risk condition for incidence of CIN even in patients with normal renal function. Pentoxifylline (PTX) with a variety of mechanisms may prevent CIN.

Materials And Methods: Between April 5, 2011, and February 20, 2012, all consecutive eligible patients referred for elective percutaneous coronary intervention were asked to participate in the study (n = 199).

A case of successful percutaneous coronary intervention for chronic total occlusion using the reversed guidewire technique.

Percutaneous coronary intervention for chronic total occlusion remains a challenging field for interventional cardiologists because of inability to advance a wire beyond the occlusion. In case that the wire is not crossed to the distal main vessel but a side branch originated from distal end of the occlusion, we applied "reversed guidewire technique" which was initially proposed as a technique for extremely angulated bifurcations with utilizing hairpin shaped wire. In this case report, we describe application of this technique for chronic total occlusion in detail with potential limitations.
