Percutaneous transluminal coronary angioplasty in dextrocardia: case report

Magnetic resonance imaging of acute myocardial infarction in dextrocardia with situs solitus (dextroversion)

The case report of an 88-year-old woman with dextroversion and acute anterior wall myocardial infarction is presented. The patient, who had been diagnosed with dextrocardia 3 years prior to this admission, presented with right-sided chest pain. Coronary angiography demonstrated an 80% proximal left anterior descending artery stenosis which was successfully stented. A cardiac MRI was performed to exclude a left atrial thrombus after an inconclusive echocardiogram. The MRI demonstrated findings consistent with dextroversion, with delayed contrast-enhanced viability sequences confirming a near transmural anterior wall myocardial infarct. To our knowledge, this is the first report illustrating the cardiac MRI findings in such a case.

Percutaneous transluminal coronary angioplasty for morphologic left anterior descending artery lesion in a patient with dextrocardia. A case report and literature review

A case report of percutaneous transluminal coronary angioplasty (PTCA) to treat coronary atherosclerotic lesions in a patient with dextrocardia associated with situs inversus totalis is presented. The patient was a sixty-two-year-old man who was admitted with a diagnosis of congestive heart failure. Cardiac catheterization was performed. Left ventriculography showed mild hypokinesis in segments 2 and 3 with ejection fraction of 63%. Coronary arteriography revealed 74% stenosis in segment 7 of the left anterior descending (LAD) artery. PTCA for this lesion was performed. Successful dilation was achieved with the residual stenosis in the LAD reduced from 74% to 34%. Performance of PTCA in patients with dextrocardia is extremely rare, and only 8 cases have been reported to date. However, by visualizing the procedure as a mirror image and choosing a guide catheter that permits good engagement, it appears possible to perform it like ordinary PTCA.
