|Abstract||Postoperative studies in patients with chronic thromboembolic pulmonary hypertension (CTPH) have shown that pulmonary thromboembolectomy (PTE) results in a rapid decrease of right ventricular (RV) size, improvement in the RV systolic function and left ventricular (LV) diastolic function. However, the extent to which the biventricular function recovers immediately after embolectomy in post-cardiopulmonary bypass period is not clear. A 45-year-old male patient was operated for retrieval of thrombus from pulmonary trunk and right pulmonary artery. Intraoperative transesophageal echocardiography (TOE) before surgery revealed signs of RV dysfunction and enlargement. The interventricular septum was seen moving paradoxically during end-systole and early-diastole. E/A ratio on transmitral Doppler flow velocity profile was about 0.63 and S/D ratio on pulmonary venous Doppler profile was 2.25, indicative of LV diastolic dysfunction. After weaning the patient from bypass, navigation on TOE showed marginal recovery of the RV systolic function and abatement of septal paradox to some extent. However, significant improvement was observed in the LV diastolic parameter (normal E/A ratio, S/D ratio of 1.08). We conclude that the geometrically altered LV recovers more than the hypertrophied and hypokinetic RV in a patient with CTPH in the post-bypass period.|

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 (NDLI) 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. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 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 (NDLI) project.
