Simultaneous thrombosis of multiple coronary arteries in acute myocardial infarction is very rare in clinical settings. Its mechanism is not yet clear, but patients displaying multivessel simultaneous thrombosis tend to have poor clinical outcomes. Hence, it is important to recognize this condition and provide timely and proper management. We report a case of simultaneous thrombosis involving multiple coronary arteries in a patient with ST-segment elevation myocardial infarction.

The retrograde approach through a collateral artery is now thought to improve the success rate of percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO), and different kinds of strategies for this technique have been developed. However, the basic principles of PCI for CTO, such as firm back-up support with a guiding catheter and fine control of the guide wire, should be adhered to more strictly to succeed with this complex procedure. We present a case in which a CTO of the proximal left anterior descending artery was successfully opened by the retrograde approach through a collateral from the left circumflex artery, during which two guiding catheters were simultaneously used in the same coronary artery for the purpose of strong back up support for the retrograde device and fine control for the antegrade device.

Percutaneous transluminal coronary angioplasty (PTCA) is often used in the management of coronary artery disease and the advances in equipment, technichal skill and acquisition of operator experiences have improved initial success rates and reduced the frequency of complications. However, acute coronary occlusion is the most common and serious complication related to angioplasty and its several potential mechanisms are intracoronary thrombus, coronary artery spasm and coronary artery dissection. Accordingly,heparinization, intracoronary thrombolysis, re-PTCA, stent implantation and emergency coronary artery bypass grafting have been previously used for reopening of an occluded coronary artery during angioplasty. In this report we describe our experience in the management of acute coronary occlusion of left anterior descending artery caused by dislodgement of thrombotic material during PTCA by means of aspiration thromboembolectomy instead of medical therapy,re-PTCA and stent implantation.

BACKGROUND AND OBJECTIVES: The impact of multivessel coronary disease (MVD) with chronic total occlusion (CTO) on one-year mortality in patients with acute myocardial infarction (AMI) is not clearly known. We investigated the impact of MVD with concurrent CTO lesion on one-year mortality in patients with AMI. SUBJECTS AND METHODS: We studied 1008 consecutive patients who underwent coronary angiography between November 2005 and December 2008 with a diagnosis of AMI. RESULTS: Among 1008 patients, 432 patients (43%) had MVD, and 88 patients (8.7%) had CTO lesion. The one-year overall mortality was higher in patients with MVD than in patients with single vessel disease (SVD) (10.2% vs. 5.9%, p=0.012). However, the one-year overall mortality was not significantly higher in patients with CTO lesion than in patients without that lesion (12.5% vs. 7.3%, p=0.080). In multivariate analysis, independent predictors of one-year overall mortality were age older than 65 years {hazard ratio (HR) 2.41, 95% confidence interval (CI): 1.43 to 4.08}, Killip class > or =III (HR 3.59, 95% CI: 2.24 to 5.77), ST-elevation myocardial infarction (HR 2.45, 95% CI: 1.49 to 4.05) and MVD (HR 1.76, 95% CI: 1.07 to 2.89). CONCLUSION: Patients with MVD showed higher one-year mortality than patients with SVD. However, the presence of CTO was not an independent predictor of one-year mortality in this study that included patients with successfully revascularized CTO lesion.

Polyarteritis nodosa (PAN) is characterized by inflammatory necrosis of medium sized arteries. PAN can also be associated with stenosis or aneurysm of the coronary artery. However, the involvement of PAN at a coronary artery is usually asymptomatic, which makes it difficult to diagnose. In addition, all of the three main coronary arteries involved with chronic total occlusion (CTO) is a rare finding in patients with PAN. We report a patient that presented with PAN complicated by CTO and aneurysms of three main coronary arteries, without typical symptoms of angina.

Passage failure of guidewire is still remained most common reason for percutaneous coronary intervention (PCI) failure in chronic total occlusion (CTO). Intravascular ultrasound study (IVUS) and cardiac CT angiography can help identify features that most influence current success rates of PCI. We report our experience using the reverse controlled antegrade and retrograde subintimal tracking technique under the aid of IVUS, cardiac CT angiography for an ambiguous CTO of proximal right coronary artery.
