[Rare congenital heart disease as a cause of tuberculosis activation].

INTRODUCTION

Patients with congenital cyanotic heart defects and the left-to-right shunt are at a three times higher risk of getting tuberculosis than acyanotic ones. No TB cases have been recorded in adult patients with the right-to-left shunt having cyanosis since their birth.

CASE REPORT: A 34-year-old man was referred to our Clinic with the discomforts such as chronic cough, hemoptysis and insomnia. At the admission he was pale, cyanotic, with a partial manifest respiratory insufficiency and characteristic TB pulmonary lesions detected by x-rays and tomography. After the sputum positive TB recidivism had been diagnosed, the antituberculotics treatment was introduced resulting in the successful smear and culture conversion and radiological regression of pulmonary lesions, but associated with non-explicable deterioration of cyanosis and chronic respiratory insufficiency until Doppler-echocardiographic examination verified the presence of tetralogy of Fallot.

CONCLUSION

Congenital cyanotic heart defects are extremely rare in adults. Nevertheless, it is necessary to maintain a very high level of clinical suspicion regarding TB activation even in the cases of defects with the right-to-left shunt.
