Case ReportsTakotsubo cardiomyopathy in a patient with previously undiagnosed hypertrophic cardiomyopathy with obstruction.
Takotsubo cardiomyopathy (TCM) is usually characterized by left ventricular anteroapical dysfunction in the absence of significant coronary disease commonly precipitated by an emotional or stressful trigger. Hypertrophic cardiomyopathy (HCM) is usually diagnosed on the basis of symptoms, family history, echocardiography, or by the presence of a characteristic murmur. We report a unique case of TCM occurring in a patient with previously undiagnosed HCM with left ventricular outflow tract (LVOT) obstruction who presented with an acute coronary syndrome and ultimately underwent successful alcohol septal ablation. The potential pathophysiologic correlations are discussed.

Value of duplex scanning in differentiating embolic from thrombotic arterial occlusion in acute limb ischemia.
Management of acute limb ischemia (ALI) is largely based on the etiology of arterial occlusion (embolic vs. thrombotic). To our knowledge, the ability of duplex scanning to differentiate embolic from thrombotic occlusion has not been previously reported. ⋯ In acute arterial occlusion, ≥ 0.5 mm dilatation or diminution in the occluded artery diameter is a useful duplex sign for diagnosing embolic or thrombotic occlusion, respectively.

Case ReportsPercutaneous mitral valve annuloplasty for functional mitral regurgitation: acute results of the first patient treated with the Viacor permanent device and future perspectives.
There is a need to develop less invasive techniques to manage moderate or severe functional mitral regurgitation in patients at high surgical risk. ⋯ PTMA is a promising technique for the treatment of severe mitral regurgitation in selected patients. Further ongoing research will determine the predictors of success and long-term safety and performance of this technique.

Case ReportsCoronary angiography of pregnancy-associated coronary artery dissection: a high-risk procedure.
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome occurring predominantly in young women without any cardiovascular risk factors, especially during the peripartum and early postpartum period. Here, we report a case of a 28-year-old pregnant woman who was found to have an isolated distal SCAD of the left anterior descending artery (LAD). Coronary angiography was complicated by extensive LAD and circumflex arteries dissection, requiring an emergency coronary artery bypass grafting associated with ventricular assist device implantation and underlying the extreme fragility of coronary arteries in pregnant women.
