- W2892015193 abstract "In this study, the authors hypothesized that intraprocedural improvement of pulmonary venous (PV) waveforms are predictive of improved outcomes. In this report, they analyzed intraprocedural invasive and echocardiographic changes with respect to rehospitalization and mortality.The effects of hemodynamic changes during percutaneous mitral valve repair (PMVR) with MitraClip (Abbott Vascular, Santa Clara, California) are incompletely characterized.The authors retrospectively reviewed records and intraprocedural transesophageal echocardiograms of 115 consecutive patients (age 76 ± 12 years) who underwent PMVR for mitral regurgitation (MR) from May 2013 to January 2017 at Emory University Hospital. They assessed intraprocedural PV waveforms for improvement in morphology, measured change in MR grade by semiquantitative methods, evaluated invasive changes in left atrial pressure (LAP) and V-wave, and compared with 30-day and 1-year rehospitalization and all-cause mortality.Ninety-three cases (80%) had PV waveforms before and after clip placement sufficient for analysis, of which 67 (73%) demonstrated intraprocedural improvement in PV morphology and 25 (27%) did not. At 24 months, 57 (85%) of those with PV improvement were living, compared with only 10 (40%) of those without improvement. Proportional hazards models demonstrated a significant survival advantage in those with PV improvement (hazard ratio [HR]: 0.28, 95% confidence interval [CI]: 0.08 to 0.93, p = 0.038). By multivariable analysis, PV improvement predicted reduced 1-year cardiac rehospitalization (odds ratio [OR]: 0.18, p = 0.044). Intraprocedural assessment of MR grade and invasive hemodynamics did not consistently predict mortality and rehospitalization.PV waveforms are important markers of procedural success after PMVR. Our data show intraprocedural PV waveforms may predict rehospitalization and mortality after PMVR. A larger, multicenter cohort will be important to clarify this relationship." @default.
