Aim

Chest pain accompanied with ECG changes and cardiac enzyme elevations are generally misdiagnosed as myocarditis if the coronary angiography does not reveal any stenotic lesion. However Multisliced computerized tomography could effectively display the etiology; a non-critically stenotic atherosclerotic plaque or myocardial bridging (MB) on coronary artery; which could not sometimes detected by conventional coronary angiography.

We aimed to present the previous and current ECG recordings and treadmill test ECG recordings and the MSCT angiography findings of three young patients with the history of misdiagnosis of myocarditis.

Cases

We presented three young cases (20, 22, and 22 years old) that were previously had been hospitalized with the ECG signs related with diagnosis of Anterior STEMI. They had been treated and anticogulated according to the STEMI and performed coronary angiography. Cardiac biomarkers indicating myocardial injury had been elevated. Their echocardiogram had been revealed left ventricular dysfunction. Coronary angiogram performed during the acute period was interpreted as normal coronary anatomy without any occlusive thrombus or atherosclerotic plaque. Thereafter they had been misdiagnosed as myocarditis due to the normal coronary angiogram. After several years period they have been applied for the employment on a physically strenuous job. Since they stated the follow up in the coronary care with the diagnosis of myocarditis in their medical history they have been performed treadmill test. Two of them had equioval ECG changes and one of them had chest pain on the stress test. They were referred to MSCTA. Three of them had myocardial bridging on the proximal or mid segment of LAD coronary artery with mild or moderate luminal narrowing diagnosed by MSCTA.
