Background. The right ventricle (RV) receives part of its systolic pumping force from the left ventricle through systolic ventricular interaction. The purpose of this study was to determine the effects of dilated cardiomyopathy on left ventricular to right ventricular (LV-to-RV) systolic interaction. Methods and Results. Studies were performed in six normal pigs and in six pigs in which dilated...

A 28-year-old male patient with bipolar disorder taking olanzapine and lorazepam for almost 10 years presented with weight gain, diabetes, and anasarca was examined in this study. Evaluation of the patient revealed he was in heart failure. The reason for his heart failure was ambiguous and an investigation into it revealed negative results. Literature search conducted showed a few reported case...

Introduction Takotsubo cardiomyopathy (TCM) is a form of acute cardiomyopathy showing left ventricular apical ballooning. Whilst the exact mechanism of TCM remains unknown, it is hypothesized that an excess of circulatory catecholamine's to an exaggerated sympathetic from an intense physical or emotional distress as the cause. We report the rare case of a 76-year-old woman who developed TCM aft...

Myocardial dysfunction is one of the main predictors of poor outcome in septic patients, with mortality rates next to 70%. During the sepsis-induced myocardial dysfunction, both ventricles can dilate and diminish its ejection fraction, having less response to fluid resuscitation and catecholamines, but typically is assumed to be reversible within 7-10 days. In the last 30 years, It's being subj...
