Background & Aim: Pulmonary hypertension is a complex problem characterized by non-specific signs and symptoms and having multiple potential causes. Delay in the diagnosis of PAH leads to postponement of treatment and thus may have deleterious effects. To determine the accuracy of palpable second heart sound for diagnosing pulmonary hypertension in children with congenital heart disease.

Study Design & Participants: In a hospital-based cross-sectional study, participants were clinically suspected children with congenital heart disease at AVBRH Hospital, Wardha.

Methods: Three pediatric residents, trained by a cardiologist for detection of pulmonary hypertension in CHD cases assessed 140 clinically suspected CHD cases. They looked for palpable second heart sound (P2) and findings were correlated with 2 dimensional echocardiography findings. Data was entered into SPSS for statistical analysis.

Results: Out of 140 cases of CHDs, 41 cases (29.2%) had pulmonary hypertension. The sensitivity, specificity, positive predictive value, negative predictive value, negative LR for palpable P2 by the first observer was 70.73%, 100%, 100 %, 89.19 % and 0.29 which was almost equal with the findings of other two observers.

Conclusion: We demonstrated that palpable second heart sounds are effective in diagnosing the presence of PAH in CHD children.
