Structural heart disease is a major cause of morbidity and mortality in children. Echocardiography is accepted as the first line cost-effective diagnostic modality for pre-operative assessment of children with structural heart diseases. Two-dimensional transthoracic echocardiography (2-D TTE) may be the only diagnostic tool in a resource-poor environment where further investigations may be very expensive and not readily available.The aim of the study is to determine the degree of accuracy of pre-operative 2-D echocardiographic diagnosis with eventual surgical (intra-operative) findings among children with structural heart diseases with a view to audit the echocardiographic diagnoses and final surgical diagnoses among the patients in the University of Nigeria Teaching Hospital Ituku-Ozalla Enugu, a tertiary cardiothoracic center in Enugu, South-east Nigeria.2-D TEE (GE Model) diagnosis of all the children that had cardiac surgery at University of Nigeria Teaching Hospital (UNTH) Ituku/Ozalla Enugu over a 3-year period was studied. All the patients had at least two echocardiographic sessions and results were recorded in a proforma. Surgical findings were obtained from post-operative surgical notes. Intra-operative findings were compared with 2-D TTE findings. Data were analyzed using SPSS version 20. The degree of accuracy was expressed as percentages. The relationship between the sensitivity of 2-D TTE and intra-operative findings as ascertained using sensitivities and positive predictive values.There were 55 pediatric cardiac operations performed within the period under review. There were 22 males and 23 females, the age range was from 8 months to 17 years. Fifty-two (94.5%) were due to congenital heart diseases, whereas three (5.5%) were due to acquired heart diseases. Echocardiographic findings were the same as surgical findings in all isolated PDAs (100%), Isolated ASDs (100%), Mitral valve regurgitation three (100%), but missed out PDA as an associated finding in a case of sub-aortic VSD (7.7%) and an ASD in a case of TOF (5.9%), congenital absence of tricuspid valve was also missed as a component of complex cardiac anomaly one (1.1%). These omissions however did not change the surgical approach and outcome. Pre-operative echocardiographic diagnoses and eventual surgical diagnoses were largely concordant. The sensitivity of 2-D TTE and intra-operative findings is 94.5%, positive predictive value is 94.5%, and the false negative rate is 5.5%.Echocardiography is a veritable diagnostic tool in the pre-operative evaluation of children with structural heart diseases. Continuous training and re-training are key in skill development and capacity building in resource-poor countries. |
