Left Main Coronary Embolism

Case Presentation. A 58-year-old female was transferred from an outside hospital with impending cardiogenic shock and pericardial effusion. She had a history of mitral regurgitation due to myxomatous degeneraton and had undergone complex mitral valve repair with quadrangular resection of the second segment of the posterior leaflet and ring annuloplasty 7 weeks prior to presentation. There was also a history of paroxysmal atrial fibrillation for which she was treated with warfarin prior to admission, as well as after surgery. She was taken emergently to the operating room for a perica



Addendum: Four Days of Percutaneous Cardiopulmonary Support and Sixteen Days of Percutaneous Left Atrium-Artery Bypass: A Case

The online case report with brief review entitled Four Days of Percutaneous Cardiopulmonary Support and Sixteen Days of Percutaneous Left Atrium-Artery Bypass: A Case Report of Survival of Acute Myocardial Infarction with Cardiogenic Shock and Severe Rhabdomyolysis was incorrectly listed in the Table of Contents of the December 2005 issue of The Journal of Invasive Cardiology (the authors’s names were correct, but the title and abstract were not). We regret this error and have provided the correct information below:

Percutaneous Stenting of the Left Main with Drug Eluting Stents for In-Stent Restenosis: Immediate- and Long-Term Results

Left main coronary artery stenosis occurs in 3–5% of patients undergoing coronary angiography. Percutaneous treatment has been limited by major adverse cardiovascular events during the follow-up period. Studies suggest bare metal stents have restenosis rates of 20–30%.1 Recent studies suggest de novo left main (LM) stenting in the drug-eluting stent (DES) era is safe and effective, with restenosis rates of 5–20%.2–4
Traditionally, treatment for LM in-stent restenosis has been coronary artery bypass surgery. There are limited data on percutaneous treatment



Percutaneous Coronary Intervention under the Rigid Restriction of Contrast Media Dose in Patients with Chronic Renal Insufficien

Exposure to contrast media occasionally induces acute renal disturbance, often called contrast-induced nephropathy (CIN).1–3 Although the impairment is transient and function spontaneously recovers in most cases, irreversible damage occurs in some patients, particularly in those with preexisting chronic renal insufficiency (CRI).3,4 The nephrotoxicity of contrast media causes serious limitations in treating coronary artery disease in patients with CRI. Prevention of CIN has been considered to be one of the most important issues for those patients, since this complicatio



Late In-Stent Thrombosis in a Patient with Systemic Lupus Erythematosus and Hyperhomocysteinemia while on Clopidogrel and Aspiri

Recent case reports of late stent thrombosis following the discontinuation of aspirin have raised the concern that drug-eluting stents might be more prone to this complication. McFadden et al reported on 4 patients, 2 who received a paclitaxel-eluting stent, and 2 who received a sirolimus-eluting stent. The time from stent implantation to stent thrombosis was 335 to 442 days. All patients had finished dual antiplatelet drugs and were being maintained on aspirin. The aspirin was discontinued for elective surgery 4 days to 2 weeks prior to stent thrombosis. Two patients received bare metal stent



Immediate- and Short-Term Outcome following Recanalization of Long Chronic Total Occlusions (> 50 mm) of Native Coronary Arteri

Chronic total occlusion (CTO) is present in approximately 30% of diagnostic angiograms. Data suggest that 10-year survival of patients with CTO is improved if the CTO is successfully recanalized.1 Percutaneous coronary intervention (PCI) of a CTO now accounts for approximately 10% of patients undergoing PCI.2–4 However, the success of recanalization with conventional wires is about 50–60%,5–7 and the impact of the new technology on recanalization is unknown. We are presenting a single-center experience with one device, the Frontrunner™ catheter (LuMe



Cold Leg in Patient with High Coated Platelets: Possible Association with the Use of Rofecoxib

Diagnostic coronary angiography in the current era is a remarkably safe procedure, yet major complications do occur. Many of these complications are related to vascular access. Although discomfort at the site of access is frequent and minor hematomas are common, one of the most potentially devastating complications is acute limb ischemia. This can relate to pre-existing atherosclerosis, prothrombotic state, catheter-induced dissection, local thrombus formation, or a combination of these factors. Prolonged use of external compression devices may also increase this risk. A new concern is whether
