Type 2 Kounis syndrome in an allergic woman: An uncommon presentation of acute coronary syndrome.

Acute coronary syndromes secondary to allergy-induced coronary vasospasm are known as "Kounis syndrome." The main pathophysiological mechanism of coronary spasm in Kounis syndrome is the release of inflammatory mediators during a hypersensitivity reaction triggered by food, insect bites, or drugs. Here, we report a case of an acute coronary syndrome secondary to allergic reaction following levofloxacin administration in a 68-year-old female without a prior history of coronary artery disease.

Peripheral arterial embolism due to a left ventricular diverticulum in a young adult.

A 32-year-old man was admitted to the emergency department of our hospital after experiencing a peripheral arterial embolism. Investigation of the possible embolic sources in an otherwise asymptomatic patient revealed the existence of a left ventricular diverticulum. The left ventricular diverticulum is a rare congenital anomaly, either isolated or as a part of a syndrome including other congenital malformations.

Acute myocardial infarction in a patient with normal coronary arteries after an allergic reaction.

The case is described of a man aged 51 years who, one hour after a coronary angiographic examination that showed coronary arteries without lesions, suffered an acute inferior myocardial infarction as the result of an acute allergic reaction, probably to the iodinated contrast agent that was used. Acute myocardial infarction following an allergy is an extremely rare clinical entity that, according to existing data, is due to the local release of vasoconstrictive substances as a result of the allergic reaction.
