Spectrum of congenital heart disease at Sheri-Kashmir Institute of Medical Sciences
Abstract
Background: Congenital Heart disease accounts for 10% of infant deaths in developed countries.Very scarce data exits about the prevalence and patterns of CHD in our local high altitude population.
AIMS : To analyse the pattern and prevalence of congenital heart disease at a tertiary care cardiac centre in a high altitude region of Northern India.
Methods: A retrospective study was conducted in the Department of Cardiology and Department of Pediatrics of our institute which is the only major referral centre of the region. Case records of 125142 patients (Age 0-16yrs) attending the hospital from November, 2013 to August , 2017 were analysed . Statistical package SPSS version 20.0 (SPSS Inc., Chicago, Illinosis, USA) was used to carry out statistical analysis of data
Results: 1596 out of the total of 125142 patients were found to have CHD giving a prevalence of 12.7 per 1000 population. About 1247 had acyanotic CHD (78.2%) of which most common was VSD (33%) followed by PDA ( 21.7%). Cyanotic heart diseases represented 21.8%(349 cases) of which TOF was most common ( 44%) followed by TGA (15%).Only three cases of a total of 53 cases of TGA were TGA IVS.DORV(8.8%) was third most common followed by Single ventricle(8.3%).Only 3 of a total of 349 cases of CCHD were HLHS. Conclusion: A prevalence of 12.7 per 1000 population is fairly high which could reflect the effect of high altitude on prevalence of CHD.Our study noted that the spectrum of CHD was mostly similar to the published literature . In addition, it draws attention to the almost negligible detection of critical congenital heart disease in the neonatal period.
