Situs inversus totalis associated with subaortic and subpulmonic stenosis.
The unusual occurrence of total situs inversus and idiopathic hypertrophic subaortic stenosis with the demonstration of right and  left heart dynamic obstruction in one patient is presented. The fact that the patient was known to have a rare abnormality (total situs inversus) and the presenting symptom being angina pectoris, may have obscured the diagnosis of IHSS and emphasized the value of comprehensive evaluation of patients. The documentation of right ventricular dynamic obstruction, in addition to obstruction of the left side of the heart, was facilitated by the use of simultaneous pressure recordings in the pulmonary artery and in the body of the right ventricle. The angina-like pain was secondary to left ventricular outflow obstruction, rather than to coronary disease.
