Atrial fibrillation in the Middle East: unmapped, underdiagnosed, undertreated.

Atrial fibrillation (AF) is the commonest persistent cardiac arrhythmia with an estimated incidence rate of between 1.5-2% and an important cause of strokes. Few epidemiological studies and clinical trials on the management of AF have been conducted outside Europe and North America.

Anomalous origin of RCA from left coronary sinus presenting as PSVT and recurrent acute coronary syndromes.

Anomalous origin of the right coronary artery from the left sinus of Valsalva and coursing between the aorta and pulmonary artery is a rare congenital abnormality representing less than 3% of the congenital coronary anomalies. Patients can present with myocardial ischemia, arrhythmias, or sudden cardiac death (SCD). This diagnosis should be suspected in young patients without risk factors for coronary artery disease and the diagnosis can be confirmed easily by 64-slice MDCT angiography.

Myocarditis and Rhabdomyolysis in a Healthy Young Man Caused by Salmonella Gastroenteritis.

Salmonella gastroenteritis is a common, self-limiting, foodborne disease and a rare cause of life-threatening complications especially in immunocompetent individuals. Moreover, bacterial infections of the GI tract have been rarely reported as a cause of serious complications like acute myocarditis and rhabdomyolysis. While viral infections are commonly associated with myocarditis, bacterial infections are infrequently seen with these conditions.
