| Abstract | Background: Real-time three-dimensional echocardiography (RT-3DE) could obtain ventricular volume and ejection fraction rapidly and non-invasively without relying on ventricular morphology. This study aims to use RT-3DE to evaluate the changes in biventricular volume and systolic function in children with ventricular septal defect (VSD) and moderate to severe pulmonary hypertension (PH) before surgery. Methods: In this study 18 children with VSD and moderate to severe PH (VSD + PH Group) and 18 healthy children of the same age (Control Group) were recruited. Biventricular volume and systolic function were evaluated by RT-3DE. The measurements included: left and right ventricular volume indexed to body surface area (BSA), stroke volume (SV) indexed to BSA, and ejection fraction (EF). Results: The results showed left and right ventricular volume indexed to BSA and SV indexed to BSA were significantly increased in VSD + PH Group (VSD + PH Group vs. Control Group), LVEDV/BSA (ml/m 2 ): 48.67 ± 21.46 vs. 25.59 ± 6.96, RVEDV/BSA (ml/m 2 ): 55.98 ± 15.35 vs. 27.69 ± 4.37, LVSV/BSA (ml/m 2 ): 24.08 ± 9.30 vs. 15.14 ± 4.29, RVSV/BSA (ml/m 2 ): 26.02 ± 8.87 vs. 14.11 ± 2.89, ( P < 0.05). While for EF in VSD + PH Group decreased (VSD + PH Group vs. Control Group), LVEF: 50.93 ± 7.50% vs. 59.38 ± 7.24%, RVEF: 45.84 ± 7.71% vs. 51.05 ± 6.90% ( P < 0.05). Conclusion: In children with VSD and moderate to severe PH, increased biventricular volume and decreased systolic function were observed with RT-3DE, but biventricular systolic function remained within acceptable limits. The children in this study recovered well after surgery without serious perioperative complications, suggesting that biventricular systolic function may help facilitate the surgical decision-making process in children with VSD and moderate-tosevere PH. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
