Transient left ventricular apical ballooning syndrome (TLVABS) is an acute cardiac syndrome mimicking ST-segment elevation myocardial infarction characterized by transient wall-motion abnormalities involving apical and mid-portions of the left ventricle in the absence of significant obstructive coronary disease. ⋯ TLVABS is a considerable differential diagnosis in ACS, especially in postmenopausal women with a preceding stressful event. Data on longterm follow-up is pending and further studies will be necessary to clarify the etiology and reach consensus in acute and longterm management of TLVABS.

Comparative Study Clinical Trial
Increased troponin I predicts in-hospital occurrence of hemodynamic instability in patients with sub-massive or non-massive pulmonary embolism independent to clinical, echocardiographic and laboratory information.
Whether in patients with acute central sub-massive or non-massive pulmonary embolism, mild troponin I increase (>0.03 mug/L) predicts in-hospital occurrence of hemodynamic instability and death independent to prognostically relevant clinical, laboratory and echocardiographic information is not fully established. ⋯ In patients with acute central sub-massive or non-massive pulmonary embolism, even mild increase in troponin I >0.03 microg/L may provide relevant short-term prognostic information independent to clinical, laboratory and echocardiographic data.

Case Reports
Transcatheter closure of a residual shunt after surgical repair of traumatic ventricular septal defect.
We report a patient with a significant residual left-to-right shunt who underwent surgical repair for traumatic VSD. This 13-year-old boy was stabbed with a pair of scissors through his heart. After initial life-saving surgery with lacerated left ventricular wall repair and VSD closure, residual VSD was noted. Six months later, we performed a successful transcatheter closure of the residual VSD with an Amplatzer muscular VSD occluder.

Tako-tsubo-like (Japanese word for octopus-catcher) left ventricular dysfunction is an enigmatic cardiomyopathy. Typically, the patients have a history of recent stressful incidents immediately preceding onset of mild to moderate chest pain, have ST-segment elevation in leads V3 through V6, ECG changes that typically demonstrate diffuse T-wave inversions and abnormal QS-wave development, discrete wall motion abnormalities involving the lower anterior wall and apex on echocardiography or left ventriculography, and limited myocardial enzyme release without evidence for hemodynamically significant coronary arterial stenoses by angiography. We describe a case of a Tako-tsubo-like left ventricular dysfunction in a 72-year-old female Italian woman.
