Hypersensitivity to proton pump inhibitors: lansoprazole-induced Kounis syndrome.
Proton pump inhibitors are commonly used in clinical practice for the treatment of peptic ulcer and gastroesophageal reflux and are well tolerated by the patients. Their use is rarely associated with hypersensitivity and anaphylactic reactions. ⋯ We report a patient who developed Kounis syndrome after taking 30 mg of lansoprazole. This is the first report of Kounis syndrome associated with lansoprazole administration in the world literature.

Assessment of medications in patients with tako-tsubo cardiomyopathy.
Tako-tsubo cardiomyopathy has been gradually recognized worldwide. However, medications for the prevention remain not to be investigated in part because the precise mechanism is unclear. We sought to examine medications before the onset of tako-tsubo cardiomyopathy, and to prove the limitation of these medications for the prevention. ⋯ Tako-tsubo cardiomyopathy can occur despite treatment with calcium channel blockers, nitrates or beta-blockers, suggesting limitation of these medications to prevent tako-tsubo cardiomyopathy.

Diagnosis of the left circumflex coronary artery fistula drainage into the left ventricle by echocardiographic color Doppler flow imaging.
Congenital coronary fistula is consisted of a communication between a coronary artery and a cardiac chamber or pulmonary vessel. Congenital left coronary artery-left ventricle fistula is uncommon. A 41-year-old female patient admitted to our institution for evaluation of heart murmur etiology. ⋯ Echocardiography showed a large fistula draining into the left ventricle apex. Coronary angiography revealed fistula from left circumflex coronary artery to left ventricular cavity. Since the patient was asymptomatic and no concomitant cardiac pathology was detected, we advised endocarditis prophylaxis and medical follow-up.

The recurrence of tako-tsubo cardiomyopathy complicated by cardiogenic shock: a case report.
Tako-tsubo cardiomyopathy is a stress-related cardiomyopathy which occurs in postmenopausal women after severe emotional stress. Although no evidence supporting specific treatment with tako-tsubo cardiomyopathy has been established, the prognosis is considered favorable with normalization of wall motion abnormalities within weeks. In addition, recurrence of this syndrome seems to be rare. Now, we report a recurrent case of tako-tsubo cardiomyopathy complicated by cardiogenic shock after repeated emotional stress.

Pheochromocytoma crisis presenting with shock and tako-tsubo-like cardiomyopathy.
Pheochromocytoma usually presents with hypertension but it may also be an unusual aetiology of cardiogenic shock in order to catecholamine induced myocardial dysfunction. We report the devastating course of a patient with tako-tsubo like apical cardiomyopathy during pheocytoma crisis who presented with classical transient left ventricular apical ballooning 6 months before.
