Review[Drug-eluting stents in multivessel coronary artery disease: Was one of the important fortresses of surgery conquered?].
Since the drug eluting stents have provided better results concerning restenosis and repeat revascularization comparing to bare metal stents, percutaneous coronary interventions are performing increasingly in more complex stenoses. However, drug eluting stents did not show any advantage on prevention of myocardial infarction and survival. ⋯ While the long-term results of drug eluting stents still unclear, everyday progressively more patients with multivessel disease are undergoing percutaneous coronary intervention with drug eluting stent implantation. The aim of this review is to discuss the efficacy and safety of drug eluting stents in patients with multivessel disease.

Valvular heart diseases still continue to be an important health problem. Surgical replacement of cardiac valves keeps a widely used treatment method for the present. However, the efficiency of minimal invasive and percutaneous methods targeted to repair and replacement of the diseased valves has been searched for nowadays. ⋯ Nevertheless, it should be kept in mind that percutaneous valvular interventions are at their development stages. Long term confidence and efficiency studies of these treatment modalities are needed. The present review emphasizes the studies on percutaneous techniques initiated in the treatment of valvular heart diseases.

Usefulness of automatic QT dispersion measurement for detecting exercise-induced myocardial ischemia.
The electrocardiographic index of QT dispersion (QTd) is related to the occurrence of arrhythmia. In patients with suspected or known coronary artery disease, QTd may be affected by exercise. We investigated whether QTd that is automatically calculated by a newly developed computer system could be used as a marker of exercise-induced myocardial ischemia. ⋯ QT dispersion and/or QTcd after exercise could be a useful marker for exercise-induced myocardial ischemia in routine clinical practice.

Levosimendan (LS) is a new inodilator agent that improves cardiac contractility by increasing the sensitivity of troponin C to calcium, which usage in cardiac surgery has been growing in the recent years. We aimed to determine the best timing of the administration of LS in high-risk patients who underwent cardiovascular surgery. ⋯ According to our experience, LS is effective in high-risk cases during cardiac surgery, especially during the intra-operative and pump removal periods;however, no successful outcomes were observed during the post-operative period. As a result, case selection and timing should be performed well when using LS.
