Case Reports
Primary percutaneous coronary intervention for acute myocardial infarction in a patient with dextrocardia.
Dextrocardia is a rare cardiac anomaly in which the heart is located in the right hemithorax. This developmental irregularity can occur in isolation as situs solitus, or in association with situs inversus or situs ambiguous. Although there are reports of coronary angiography in patients with dextrocardia, there are very few reported cases of mechanical intervention. We report a patient with dextrocardia and situs inversus who presented with an ST segment elevation myocardial infarction and was successfully treated with primary percutaneous coronary intervention.

Negative T wave and lack of ST segment elevation in predischarge ECG in ST-segment elevation myocardial infraction (STEMI) patients are given as markers of good prognosis. Repolarization duration, especially its late part (TpeakTend - TpTe), likewise ST-T patterns, is related to local post-myocardial infarction myocardial attributes. We analyzed the differences in QT parameters in STEMI patients with negative or not-negative T wave pattern in predischarge ECG. ⋯ STEMI patients who underwent successful percutaneous coronary intervention of infarct-related coronary arteries and demonstrated persistent ST elevation, without negative T wave at hospital discharge, had a longer repolarization duration, especially the late phase of it. Further studies are necessary to assess the prognostic value of this finding.
