Brief Summary

Transcatheter mitral valve repair in the form of MitraClip® is a safe and effective alternative to surgical mitral valve repair/replacement in patients with high operative morbidity and mortality risk. Successful MitraClip application depends on intraprocedural quantification of mitral regurgitation and left atrial pressure (LAP) monitoring. The pleth variability index (PVI) is a noninvasive, dynamic index based on analysis of the respiratory variations in the plethysmographic waveform recorded transcutaneously by the pulse oximeter. Studies demonstrate that PVI is accurate in predicting fluid responsiveness in mechanically ventilated adult patients. In this study, we wish to measure PVI during TMVR and correlate with invasive indices such as left atrial pressure (LAP) and stroke volume variation. Our study hopes to provide a real-time non-invasive alternative to invasive indices to better guide fluid management and improve hemodynamics.

Outcome Measures

Primary Outcomes (1)

  • Delta PVI to Delta LAP Correlation During MitraClip Placement

    Delta pleth variability index (PVI) and delta left atrial pressure (LAP) are calculated by subtracting the values of LAP (as obtained intraprocedurally) and corresponding PVI value (as recorded by the Masimo Radical-7 probe) from the LAP and PVI value respectively after MitraClip placement. The delta PVI and delta LAP for the sample patient population are correlated to obtain the Pearson correlation coefficient and p-value

    Intraprocedure

Study Arms (1)

Patients for TMVR

EXPERIMENTAL

Patients with severe mitral regurgitation scheduled for TMVR procedure at Henry Ford Hospital - main campus.

Device: PVI measurement

Interventions

Masimo Radical-7® probe to be attached to patient's finger along with standard ASA monitors at the start of procedure. After placement of arterial line, stroke volume variation (SVV) and pulse pressure variation (PPV) to be recorded along with pleth variability index (PVI) every 5 minutes. Intraprocedure left atrial pressure (LAP) (v-wave and mean) to be recorded prior to and after MitraClip deployment. Data to be analyzed - age, sex, BMI; Preprocedure ejection fraction (EF), pulmonary artery pressure (PAP), rhythm, mitral regurgitation severity; heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) every 5 minutes; SVV, PPV, PVI every 5 minutes; LAP prior to mitraclip deployment; LAP after mitraclip deployment

Patients for TMVR

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male and female patients with mitral regurgitation undergoing transcatheter mitral valve repair(TMVR) with Mitra-Clip(R) at Henry Ford Hospital - Main Campus.

You may not qualify if:

  • MitraClip(R) procedure unsuccessful (defined as no clip deployment and/or procedural interruption due to complication), concomitant aortic regurgitation or stenosis of moderate or greater degree existed, patients with grade II or above diastolic dysfunction on echocardiography, previous mitral valve intervention (either surgical or percutaneous), patients requiring continuous vasopressor infusions during the procedure, or patients in whom PVI monitoring was not performed due to technical issues, patients with atrial fibrillation, or preprocedure moderate or greater mitral stenosis
