Current status and prospective of echocardiography in evaluating right ventricular lead Induced tricuspid regurgitation / 医学研究生学报

The Lead-Induced Tricuspid Regurgitation(LITR)is defined as new-onset or progressive tricuspid regurgitation ( TR) due to endocardial leads .As a complication of pacemaker , LITR has not been fully recognized neither clinically or echocardio-graphically for a long time .Conventional two-dimensional echocardiography has some inherent limitations in identifying tricuspid valve morphology and diagnosing the LITR .Recently, three-dimensional echocardiography has been developed for assessing anatomical rela -tionship between the lead and the tricuspid leaflets , which is a promising modality to explore the mechanism of LITR .A better under-standing of LITR could help optimize the preventative and treatment strategies .
