Cardiac contusion: ending myocardial confusion in this capricious syndrome.
Symptoms of cardiac contusion are very greatly and sometimes are non recognized or are masked by associated injury in severe chest trauma. Cardiac contusion clinically presents as a spectrum of signs and symptoms of varying severity, ranging from precordial pain, dyspnoea, and non specific ECG changes to increased serum activity of several enzymes, early severe rhythm abnormalities, severe conduction defects and death. ⋯ All clinical data were suggestive of acute myocardial infarction, but the history of chest wall injury and gross and histological examination of the heart and coronary vessels led us to conclude for a cardiac contusion without myocardial infarction. In case of chest blunt trauma, the ECG should be interpreted within the context of the clinical situation, on history of chest wall injury, since a fatal myocardial contusion may occur after apparently mild injury.

Echocardiographic diagnosis of syndrome of left ventricular-right atrial shunt (Gerbode defect).
Left ventricular-to-right atrial communications are rare types of ventricular septal defect known collectively as the Gerbode defect. These defects are usually congenital and they have also been reported after bacterial endocarditis and after acute myocardial infarction. Echocardiography is the most useful diagnostic method. We describe a case of echocardiographic diagnosis of Gerbode defect in a 68-year-old Italian woman.

Effects of levosimendan versus dobutamine on left ventricular diastolic function in patients with cardiogenic shock after primary angioplasty.
Levosimendan is a new calcium sensitizer with positive inotropic properties. In previous studies, it has recently been shown that levosimendan improves the Doppler echocardiographic parameters of the left ventricular (LV) diastolic function in patients with anterior acute myocardial infarction. We sought to evaluate the effects of levosimendan compared to dobutamine on LV diastolic function, using conventional transmitral Doppler, in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) who subsequently developed cardiogenic shock. ⋯ Levosimendan seems to be effective in improving the Doppler echocardiographic parameters of LV diastolic function in patients with STEMI revascularised by primary PCI who developed cardiogenic shock.

Comparative Study
Midregional pro-atrial natriuretic peptide is a useful indicator for the detection of impaired left ventricular function in patients with coronary artery disease.
We compared the diagnostic performance of N-terminal pro-brain natriuretic peptide (NT-proBNP) with a newly developed assay for the midregional part of pro-atrial natriuretic peptide (MR-proANP) concerning the detection of impaired left ventricular ejection function (LVEF) among patients with coronary artery disease (CAD). ⋯ MR-proANP is a useful indicator for the exclusion of a preserved left ventricular function in patients with coronary artery disease. The study demonstrates that the diagnostic performance of MR-proANP is comparable to the "gold standard" NT-proBNP.
