Key result
Preoperative discontinuous intrarenal venous flow patterns were independent prognostic determinants for all-cause death and heart failure hospitalization after transcatheter edge-to-edge repair.
Why the study?
Does a preoperative discontinuous intrarenal venous flow pattern predict all-cause death and heart failure hospitalization in patients with secondary mitral regurgitation undergoing TEER?

Preoperative assessment of intrarenal venous flow waveforms by Doppler ultrasonography may serve as a powerful prognostic marker for patients with secondary mitral regurgitation undergoing TEER.
ing TEER. 5, In previous studies, serum creatinine and glomerular filtration rate (GFR) have been as indicators of renal function, and they are powerful prognostic factors in cardiovascular disease. 7,8The sympathetic system and the renin-angiotensin-aldosterone system (RAAS) control the circulation M itral transcatheter edge-to-edge repair (TEER) using the MitraClip TM (Abbott Santa Clara, CA, USA) system is useful as a surgical treatment for severe secondary mitral regurgitation (MR). 1,2However, there are patients for whom TEER does not lead to an improved prognosis.The mitral valve anatomy and left ventricular morphology define the postoperative prognosis, 3,4 and renal dysfunction is also recognized as one of the most important prognostic factors in patients undergo-Article p ????

Kikuchi et al. (2023) conducted an editorial in Secondary mitral regurgitation (n=105). Discontinuous intrarenal venous flow (IRVF) pattern vs. Continuous intrarenal venous flow (IRVF) pattern was evaluated on All-cause death and heart failure hospitalization. Preoperative discontinuous intrarenal venous flow patterns were independent prognostic determinants for all-cause death and heart failure hospitalization after transcatheter edge-to-edge repair.
