| Abstract | Background A significant proportion of patients presenting for isolated aortic valve replacement (AVR) demonstrate some degree of functional mitral regurgitation (fMR). Guidelines addressing concomitant mitral valve intervention in those patients with moderate fMR lack strong evidence-based support. Our aim is to determine the effect of untreated moderate fMR at the time of AVR on long-term survival. Methods All patients undergoing isolated AVR from 2000 to 2013 at our institution were retrospectively reviewed. Patients were stratified according to severity of preoperative fMR; 0–1+ MR (Group NoMR, n = 1826) and 2–3+ MR (Group MR, n = 330). All patients in Group MR were propensity-matched with patients in Group NoMR to control for differences in baseline characteristics. The primary outcome of interest was overall survival. Results Propensity analysis matched 330 patients from each group. Mean age was 77.9 ± 10.0 years and 50.6% were male. There were no differences in baseline demographics, echocardiographic parameters, or co-morbidities between groups. Kaplan-Meier analysis showed significantly worse medium and long-term survival in Group MR compared to Group NoMR (log-rank p = 0.02). Follow-up echocardiography showed slightly more severe MR in Group MR (1.1 ± 0.7 MR vs. 0.8 ± 0.7 NoMR, p = 0.03) at 1 year. Conclusions Patients undergoing isolated AVR with concomitant 2–3+ fMR experience poorer long-term survival than those patients with no or mild fMR. This suggests that mitral valve intervention may be necessary in patients undergoing AVR with clinically significant fMR. |

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.
