Acute myocardial infarction in a young man caused by centipede sting.

It is known that insects can cause various clinical effects such as myocardial ischaemia and hypotension from vasospasm and the myocardial toxic effects of the venom and anaphylaxis. Although myocardial ischaemia resulting from centipede sting has been reported once before, myocardial injury has not. In this report, the authors present the case of a 20 year old male patient bitten by a centipede and admitted to the emergency room with chest pain, abnormal electrocardiographic findings, and increased cardiac enzymes (cardiac troponin T) suggesting acute myocardial infarction.

Atrial fibrillation after electrical shock: a case report and review.

A 52 year old man was admitted to an emergency department with a fast ventricular rate atrial fibrillation after an electrical shock. Electrical cardioversion was attempted after echocardiographic examination. This failed, but the heart rate slowed. Successful pharmacological cardioversion was achieved after 16 hours of amiodarone infusion. Pre-excitation syndrome was detected on baseline echocardiograph. Serum cardiac specific markers were all within normal limits. No abnormal findings were detected by chest radiography, echocardiographic, or coronary angiographic investigations. Acute onset atrial fibrillation after electrical injury is discussed.

Cardiac emergencies caused by honey ingestion: a single centre experience.

An unusual type of food poisoning is commonly seen in the Black Sea coast of Turkey attributable to andromedotoxin containing toxic honey ingestion. This study is a retrospective case series of 19 patients admitted to an emergency department in 2002, poisoned by "mad" honey. All of the patients had the complaints of nausea, vomiting, sweating, dizziness, and weakness, several hours after ingesting "mad" honey. Physical examination showed hypotension in 15 patients, sinus bradycardia in 15, and complete atrioventricular block (AVB) in four patients on admission. Two patients with bradycardia and two with AVB fell and injured their heads. Three of them presented with local haematoma. One patient had a 6 cm cut on his head without any neurological deficit and his cranial computed tomography imaging was normal. Hypotension and conduction disorders resolved with atropine treatment, resulting in complete recovery within 24 hours.

Primary cardiac angiosarcoma.

Primary malignant cardiac tumors are extremely rare neoplasms. About three-quarters of all cardiac tumors are histologically benign. A 24-year-old man presented to the hospital with dyspnea and chest pain. A solid, dense, nonhomogeneous and rough-surfaced mass (89 x 90 x 36 mm) with protrusion into the right heart cavities was observed on transthoracic echocardiography. The findings were confirmed by transesophageal echocardiography and magnetic resonance imaging. The histopathology of the mass confirmed a diagnosis of angiosarcoma. No evidence of an extracardiac origin of the tumor was found by radiological body imaging. The patient died 2 months after presentation to the hospital.

Left ventricular inflow normal or pseudonormal. A new echocardiographic method: diastolic change of left atrial diameter.

UNLABELLED: Mitral flow Doppler study has been used to evaluate left ventricle (LV) diastolic function. Through its use, greater A wave than E wave, pseudonormal pattern, and restrictive pattern were observed progressively in patients with more LV diastolic dysfunction. Differentiation of normal or pseudonormal mitral flow is very important. In this study, left atrium (LA) diameter change during diastole was used as a new method for the differentiation of normal and pseudonormal mitral flow. METHOD: Sixty-eight patients (30 men, 38 women; mean age 53 +/- 13 years) with echocardiographically determined diastolic dysfunction and 60 healthy volunteers (36 men, 24 women; mean age 49 +/- 12 years) were included in the study. Mitral flow E/A ratio, isovolumetric relaxation time (IVRT), and deceleration time (DT) of E wave were used for determination of the diastolic dysfunction. Thirty of 68 diastolic dysfunction patients had A>E wave, 20 had pseudonormal mitral flow pattern, and 18 had restrictive mitral flow pattern. Left parasternal long-axis echocardiographic window was used for the measurement of LA diameter. Left atrium emptying fraction (LAEF) was defined as ratio of end-diastolic LA diameter to end-systolic diameter. RESULTS: LAEF was found 0.69 +/- 0.01 (mean +/- SE) in the control group, 0.76 +/- 0.01 in the A>E group (P < 0.05, control vs A > E group), 0.83 +/- 0. 05 in the pseudonormal pattern group (P < 0.05, control vs pseudonormal pattern group), and 0.87 +/- 0.01 in the restrictive pattern group (P < 0.001, control vs restrictive pattern group). CONCLUSION: (1) LV diastolic dysfunction reduces the filling of LA content to the LV during diastole; (2) LA diameter changes during diastole as a new and practical method for the differentiation of the normal-pseudonormal mitral flow pattern.

Interventricular septal hydatid cyst.

In this report we describe an unusual case of cardiac echinococcus located in the interventricular septum invaded by a cystic mass. It was demonstrated by using transthoracic echocardiography (TTE) and confirmed with magnetic resonance imaging (MRI). Surgical excision (cystopericystectomy) was performed on the patient as a curative therapy. Early recurrence was observed despite additional medical therapy with albendazole.

A case of myocardial infarction with sumatriptan use.

Sumatriptan is widely used in the treatment of acute attacks of cluster headache. It is a serotonin-1 (5HT-1) agonist. Several studies have reported an association between sumatriptan use and myocardial infarction, possibly due to the generalized vasoconstrictive nature of this agent. We report a 16-year-old male patient presenting with acute inferior myocardial infarction after sumatriptan use without any known risk factors of coronary artery disease.
