|Abstract||The long-term follow-up was analysed for 25 patients above the age of 12 years who had patent ductus arteriosus with severe pulmonary hypertension and had undergone surgical closure. There were 11 males and 14 females (age range 12-27 years; mean 18.6 years). There were 2 early and 2 late deaths. All the 21 survivors were followed up at regular intervals for 8-10 years. They were assessed by haemodynamic study: 13 of the 21 survivors underwent a study 6 months to 1 year after surgery and another 4 patients, 8 years after surgery; 7 patients of the 13 had a second study 8-10 years after surgery. The pulmonary artery systolic and mean pressures regressed to 50% of the preoperative level in the first study for 15 patients, and in the second study 2 patients had further drop in pulmonary artery pressures; however, the pressure levels never reached normal values. The pulmonary vascular resistance did not show a correspondingly significant fall. In conclusion, the ten-year follow-up shows that the patients have benefited by the surgery though the pressures have not come down to normal levels, and that they have to be followed up closely to assess the natural history of residual pulmonary hypertension and pulmonary vascular disease and its effect on their quality of life.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDL India) pilot project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDL India is designed to hold content of any language and provides interface support for leading Indian languages. It is being arranged to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular form of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examination, 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. The pilot project is devising a framework that is being scaled up with respect to content volume and diversity to serve all levels and disciplines of learners. It is being developed at Indian Institute of Technology Kharagpur.
NDL India 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 respective organization from where the contents are sourced and NDL India has no responsibility or liability for these. Every effort is made to keep the NDL India portal up and running smoothly. However, NDL India takes no responsibility for, and will not be liable for, the portal being unavailable due to technical issues or otherwise.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDL India) pilot project.
