Association between cardiovascular implantable electronic devices and tricuspid regurgitation: a case- control study

摘要

Cardiovascular implantable electronic devices(CIEDs)are widely used in the modern era.Every year,about 730,000 permanent pacemakers and 330,000 CIEDs are implanted worldwide.CIEDs have been known to increase the life expectancy of millions of people and improve their quality of life by controlling the heart rate and atrioventricular and interventricular synchronization and preventing sudden cardiac death.[1]The tricuspid valve consists of the annulus,leaflets,chordae tendineae,and papillary muscles.Interaction between the endocardial lead and any component of this structure can lead to tricuspid valve dysfunction,thereby resulting in tricuspid regurgitation(TR).[2]CIED-related TR has been shown to be an independent predictor of hospitalization for heart failure.[3,4]
