Background: Functions of the respiratory and cardiovascular systems have a close relationship and so are the pathologies that result in morbidities. Congenital heart disease (CHD) can affect the respiratory system and result in respiratory morbidities. Recurrent respiratory infection is one such morbidity resulting due to such an association.

Aim: To assess the incidence of CHD in patients presenting with recurrent lower respiratory tract infection (LRTI) and the incidence of different types of CHD in patients detected with congenital heart defects

Materials and Methods: A total of 100 patients with recurrent LRTI were studied (N = 100), which included 60 males and 40 females. All patients were subjected to clinical examination and were made to undergo chest X-ray, electrocardiography, and 2D echocardiography with color Doppler to detect CHD.

Results: Of the 100 patients, 41 patients (21 [52.8%] males and 20 [47.8%] females) with recurrent LRTI were found to have CHD.

Conclusions: The results reveal that CHD is a major cause for recurrent LRTI. Considering this, it would be prudent to screen all children presenting with recurrent LRTI for CHD in day-to-day practice.
