Abstract:
Introduction: Dextrocardia is a rare clinical entity, with the location of the heart, and apex
orientation to the right, with an incidence of 0.2-1%, and associated with situs inversus in 1/3 of the
patients. In the absence of other structural modifications it presents no cardiovascular rise, the risk of
coronary artery disease (CAD) being similar to that of the general population. Dextrocardia was first
described by Fabricius H. in 1606, but situs inversus - by Severinus M. in 1643. It often associates with
other congenital malformations (CM) - single ventricle, ventricular septal defect, tricuspid atresia.
Clinically, dextrocardia shows no manifestations, except when associated with severe CM. Its
confirmation needs a standard ECG, with the electrodes placed on the right, and an EchoCG evaluation.
Clinical case. Patient B., 62 years, admitted in PMSI MCH „Holy Trinity”, Acute Miocardial
Infarction (AMI) Department with the Diagnose: Ischaemic cardiopathy. Unstable Angina.
Miocardial infarction (1991). NYHA II HF. Dextrocardia.
At onset it presents with constrictive retrosternal pain at little physical activity lasting 15
minutes, suppressed by 3 tablets of nitroglicerine and inspiratory dyspnea. From history, in 1991 the
patient underwent an AMI. Regular treatment with cu p-blockers, diuretics, antiagregants. On
physical examination: overall condition of medium severity; normal-colored skin; vesicular breath
sounds; rhithmic heart sounds, HR-70 b/min, B P -130/80 mm/Hg; painless abdomen on palpation.
On standart ECG-microvoltage, heart electric axis(HEA)- right deviation, negative P wave,
inversed T wave in D I and AVL, R wave decrease from VI to V6. Right ECG: sinus rhythm, HR60 b/min., normal HEA. Left ventricle(LV) hypertrophy. Antero-septal and apical LV postinfarction sequelae. EchoCG: Dextrocardia; ascending Aorta wall induration; moderate dilation of
the LA, RA and LV; hypertrophy of the LV myocardium; adequate LV contractility (EF-57%); LV
antero-septal hypokinesia and apical akinesia. Mild PHT. Abdominal USG: Situs inversus.
Laboratory tests - no deviations. The patient received the following treatment: anticoagulants,
antiplatelets, nitrates, P-blockers, statins, metabolic drugs.
Conclusion: Pacient B., 62 years, with dextrocardia and myocardial infarction develops an
unstable angina, with typical clinical signs. The patient is hospitalized, following treatment according to
the clinical guidelines, with positive results. In the specialized literature, patients with dextrocardia, in
the absence of CM, need no particular approach of CAD, which was also seen in the case above.
