Chronic active Epstein-Barr virus (CAEBV) infection is characterized by chronic or recurrent infectious mononucleosis-like symptoms and the prognosis of CAEBV infection is quite poor. The incidence of myocarditis as a complication of EBV infection is not so high and it is unusual that heart failure appears as the initial symptom. However, it is very important to detect and treat chronic active myocarditis in the early phase of CAEBV infection because chronic active myocarditis disorganizes and decreases cardiomyocytes, resulting in the progression to heart failure. ⋯ Immunohistological analysis of biopsies revealed that the infiltrating cells were mainly T lymphocytes. And some of the infiltrating cells showed a positive signal for the EBV-encoded small nuclear RNA by in situ hybridization. Positron emission tomography using (18)F-fluoro-2-deoxyglucose ((18)F-FDG) performed revealed increased uptake of (18)F-FDG of whole left ventricular wall with mild heterogeneity.

Comparison of fluoroscopic coronary angiography and multi-slice coronary angiography in the characterization of anomalous coronary artery.
Anomalous coronary arteries with an inter-arterial course are associated with sudden cardiac death. We reported a study comparing the accuracy of fluoroscopic coronary angiography (FCA) with that of multi-slice computed tomography (MSCT) coronary angiography in determining the proximal course of anomalous coronary arteries. Twelve patients with thirteen anomalous coronary arteries had both FCA and MSCT coronary angiography were included in this study. ⋯ None of the cardiologists was correct in determining the proximal course of all anomalous coronary arteries. The median number of anomalous coronary arteries with their proximal courses correctly identified by the cardiologists was 7.5 (range 3-12). In conclusion, FCA was limited in delineating the proximal course of anomalous coronary arteries in comparison with MSCT coronary angiography.

To describe the short-and long-term outcome among patients with an ST-elevation myocardial infarction (STEMI), assessed and treated by the emergency medical services (EMS) in relation to whether they were fast tracked to a coronary care unit (CCU) or admitted via the emergency department (ED). ⋯ Among patients transported with ambulance due to STEMI there was a significant association between early recognition and treatment followed by fast tracking to the CCU and long term survival. A higher rate of and a more rapid revascularisation were probably of significant importance for the outcome.

Percutaneous treatment of stenoses involving aorto-ostial lesions is technically demanding and has been associated with lower procedural success and poorer clinical and angiographic outcomes when compared with non-ostial lesions. This study evaluated the immediate and long-term (2-year) outcome of aorto-ostial stenoses treated with paclitaxel-eluting stents (PES). ⋯ Utilization of PES in this complex lesion subset is feasible and associated with favorable angiographic results at 7 months. However, the gradual increase in later events up to 2 years suggests that aorto-ostial disease remains problematic even in the era of drug-eluting stents.

Atrial fibrillation after cardiac surgery: risk factors and their temporal relationship in prophylactic drug strategy decision.
Postoperative atrial fibrillation (AF) is a vexing problem in cardiac surgery. Our aim was to identify risk factors between surgical procedures, all having cardiopulmonary bypass (CPB) in common, and how AF contributes to early and late mortality. ⋯ In addition to the accepted risk factors of AF, primarily age, we emphasize the importance of considering details at CPB weaning, a correlation that was coronary specific. The weaning period hides valuable information that can be useful for more specific AF-prophylactic strategies. The AF-related increase in late mortality after CABG but not after valve procedures is intriguing, and draws attention to possible AF recurrence during patient follow-up and management.
