RESUMO
Human laterality disorders comprise a group of diseases characterized by abnormal location (situs) and orientation of thoraco-abdominal organs and vessels across the left-right axis. Situs inversus totalis is mirror image reversal of thoraco-abdominal organs/great vessels. Situs ambiguus, better known as heterotaxy, is abnormal arrangement of thoraco-abdominal organs across the left-right axis excluding situs inversus totalis. Heterotaxy, also referred to as atrial or atrial appendage isomerism, is characterized by abnormal location of left-sided or right-sided organs with loss of asymmetry of normally paired asymmetric organs. It is associated with a variety of anomalies involving the heart, great vessels, lungs and intra-abdominal organs. Right and left atrial isomerism are associated with multiple complex congenital cardiac and vascular anomalies, many of which are lethal when untreated. Isomerism may also affect the lungs, spleen, liver, gall bladder, and intestines. Innovative surgical therapy of heterotaxy/isomerism has reduced early mortality and markedly improved long-term prognosis.

Statins are among the most frequently prescribed drugs as they effectively lower cardiovascular mortality. Atherosclerotic plaques are stabilized and lipid levels are lowered, as statins inhibit 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. Patients placed on these drugs frequently report muscle aches, but true myositis that would call for discontinuance of the drug is actually uncommon. Workup for statin-induced myositis would require ruling out other causes of myositis and muscular dystrophies, and this can often be perplexing for the primary care physician to whom these patients initially present. This case report and recommendations may serve as a helpful guide.
