| Abstract | Despite the evolution of surgical techniques, coronary artery bypass graft surgery is complicated by early and late graft failure. While late graft failure is usually due to progression of the underlying disease, early graft failure can be caused by technical mistakes at the level of anastomoses. Thermal Coronary Angiography (TCA) has been developed to detect intraoperative graft failures. The method is based on the small temperature gradient that is produced by the inflow of blood into the graft and can be detected using an infrared scanner. TCA is a non-invasive method that requires no ionizing radiation or contrast documents. It allows to demonstrate graft patency of venous and arterial grafts and allows evaluation of perfusion after revascularization. It is also helpful detect distal stenoses in native coronary arteries. With the development of total endoscopic coronary artery bypass graft procedures using robotic assistance endoscopic TCA may prove to be a valuable tool for quality control in an endoscopic setting. Its value in the field of pediatric cardiac surgery for congenital disease involving reimplantation of coronaries needs yet to be explored. In summary, TCA is a valuable tool for intraoperative quality control in coronary artery bypass graft procedures and helps to minimize the risk of postoperative complications following myocardial revascularization. |

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.
