Severe Left Main Coronary Artery Spasm?
Case History. A 59-year-old man with a history of percutaneous coronary intervention of the right coronary artery (RCA) was admitted with unstable angina. An electrocardiogram revealed T-wave inversions and non specific ST changes in leads II, III, a…
Acute Myocardial Infarction Due to Left Main Compression Aortic Dissection Treated By Direct Stenting
ABSTRACT: We describe a case of acute myocardial infarction (AMI) due to compression of the left main coronary artery (LMCA) by a false channel created by an acute aortic dissection (AAD). The dynamic pattern of artery obstruction is detailed as a k…
Conservative Management of Ascending Aortic Dissection Caused by Percutaneous Coronary Intervention
ABSTRACT: Despite notable refinements in percutaneous coronary intervention (PCI) techniques, these procedures are still associated with some morbidity and mortality. A case of elective coronary angioplasty is described that was complicated by corona…
Utility of Non-Contact Three-Dimensional Mapping of the Left
Atrium for Ablation of Left Atrial Tachycardia
ABSTRACT: A 78-year-old man with a highly symptomatic left atrial tachycardia, refractory to medical therapy, was referred for radiofrequency catheter ablation. Using a double trans-septal technique, two long sheaths were placed across the interatri…
CME Offering:Treatment of In-Stent Restenosis for Saphenous Vein Grafts Using Intravascular Brachytherapy: Regulatory Challenges
Learning objectives. At the conclusion of this activity, the participant should be able to: 1) discern that SVG lumen diameters extend over a larger range than do native vessels, and this article provides justification for treating this increased ran…
Treatment of Long, Diffuse In-Stent Restenosis with
Sirolimus-Eluting Stents
ABSTRACT: Treatment of long, diffuse in-stent restenosis remains a therapeutic challenge. We report the successful use of multiple sirolimus-eluting stents (three 33-mm long stents) in a long, diffuse in-stent restenotic lesion. No major adverse card…
Cutting Balloon for Bifurcation Lesions Jailed by NIR Stent
With the increasing use of stents, sidebranch compromise after stent deployment in the parent vessel has been a matter of concern. In such bifurcation lesions, it is hard to obtain initial success. Moreover, they carry a high risk of restenosis. Alth…
Role of Enoxaparin in the Invasive Management of the ACS Patient
Compared to unfractionated heparin (UFH), enoxaparin has many advantages in the management of acute coronary syndromes (ACS). Rapidly and reliably absorbed after subcutaneous administration, enoxaparin has pharmacodynamic and pharmacokinetic profiles…
The Safe-Cross system, which includes a monitor, straight (single marker) and angled (double markers) catheter, and straight and angled guidewires.
Recanalization of Chronic Total Occlusion After Conventional Guidewire Failure: Guided by Optical Coherent Reflectometry and Fac
ABSTRACT: The success rate of percutaneous recanalization of chronic total occlusion remains low. The Safe-Cross wire, which utilizes the principle of optical coherent reflectometry for guidance and has the ability to deliver radiofrequency energy fo…
Treatment of Chronic Total Occlusions Using Optical Coherent Reflectometry and Radiofrequency Ablative Energy: Incremental Succe
Chronic total occlusions (CTO) account for 10–15% of patients undergoing coronary angioplasty. Recanalizing CTO has been a challenge to the interventional cardiologist because of the inability to visualize the vessel lumen and/or cross the hard fibro…
