Type and severity of valvular involvement in pediatric rheumatic heart disease patients

ABSTRACT

To assess frequency and severity of type of valvular involvement in pediatric patients with Rheumatic Heart Disease. This descriptive study was conducted in the Department of Pediatric Cardiology Children Hospital Complex, Multan from April 2008 to April 2010. The data of all pediatric patients below 15 years of age undergoing detailed cardiac evaluation including ECG, X-Ray and Echocardiography were reviewed. Only new cases of Rheumatic Heart Disease were studied for type and severity of valvular involvement. The data was analyzed using SPSS version 13. A total of 2381 echocardiograms were performed during the study period. 190 [08%] patients were diagnosed as having Rheumatic Heart Disease. Mitral regurgitation was the commonest lesion In 148 [77.9%] patients mitral regurgitation was found either alone [104, 54.7%] or in combination [44, 23.2%] with other lesions. In 50 [26.3%] patients aortic regurgitation was found either alone [06, 3.2%] or in combination [44, 23.2%] with other lesions. Mitral stenosis was found in only 14 [7.4%] patients. No patient had Rheumatic tricuspid or pulmonary valve. Amongst mitral regurgitation patients 54 [28.4%] had severe MR, 76 [40%] had moderate MR and 18 [9.5%] had mild MR. Amongst aortic regurgitation patients 06 [3.2%] had severe AR, 18 [9.5%] had moderate AR and 26 [13.7%] had mild AR. The commonest combination lesion was MR + AR which was found in 44 [23.2%] patients. The commonest valve involved in patients with Rheumatic Heart Disease was mitral valve followed by aortic valve. Regurgitant lesions are much more common in our younger age group patients as compared to the adult Rheumatic patients in whom mitral stenosis is usually the common lesion
