We report a 47 year-old male patient with coexistence of left ventricular noncompaction and Brugada syndrome. He presented malignant ventricular arrhythmias followed by cardioverter- -defibrillator implantation, atrial fibrillation and flutter and progressive heart failure. This case could be an example of the coexistence of two rare diseases of various genetic patterns that only partially showed overlapping symptomatology and complications, particularly ventricular arrhythmias.

Prolonged corrected QT interval (QTc) holds independent prognostic importance in predicting mortality in patients with coronary artery disease, diabetes mellitus and congestive heart failure. However, its association with all cause or cardiac mortality in the general population remains unclear. We evaluated the relationship between prolonged QTc and total mortality among patients with syncope. ⋯ In elderly patients presenting to the emergency department with syncope, QTc interval ≥ 500 ms helps identify patients at higher risk of adverse outcomes.

Levosimendan (L) is used in clinical practice for the treatment of severe heart failure (HF); it has inotropic and vasodilatory effects, without increasing myocardial oxygen consumption. In acute HF, levosimendan improves hemodynamic parameters; previous studies have demonstrated that it has favorable effects on left ventricular (LV) diastolic function. The aim of our study was to evaluate the effect of on LV long-axis function that represents the earlier marker of diastolic dysfunction. ⋯ L therapy, without loading dose, improves NYHA class and ventricular function in patients with acute HF; we believe that these prolonged hemodynamic effects are due to active metabolities of L.
