Involvement of Right Ventricle Function in Children with Dilated Cardiomyopathy.

Right ventricle involvement is frequent in pediatric dilated cardiomyopathy and is associated with worse parameters like left ventricular dimensions, ejection fraction and vacuolar involvement. Now there is growing interest regarding the clinical relevance of RV functional assessment in the heart failure population .Hence, this study was designed to estimate the incidence of RV dysfunction by different echocardiographic parameters in children with dilated cardiomyopathy (non-ischemic).

METHODS

A cross sectional observational study with consecutive sampling was conduct in the department of Cardiology, CH&ICH, Lahore from October 2019 for 6 months after approval from ethical committee. Data collected by performing echocardiography-using Performa by pediatric cardiologist. All the data was entering in SPSS-22 and then analyzed for statistically significant outcomes. The chi-square test used to measure the association among the different categorical variables.

RESULTS

48 children of diagnosed case of DCMP were selected. Male were 50% .Out of 48 children 10 patients presented with mild LV systolic dysfunction,13 patients with moderate LV systolic dysfunction while 25 patients presented with severe LV systolic dysfunction. 19 patients showed RV dysfunction ie 39.6%, 36 patients showed septal paradox, 30 patients were with normal RV diastolic function and 18 were presented with RV diastolic dysfunction.

CONCLUSION

Dilated cardiomyopathy is primary disease of LV, however certain patients presented with sign and symptoms of right heart failure resulting from RV dysfunction. There was significant involvement of RV dysfunction found ie 39%. Echocardiography helps in the detection of RV involvement in DCMP.
