ReviewUse of the ClearSight® System for Continuous Noninvasive Hemodynamic Monitoring during Heart Valve Interventions: Review of the Literature and Single-Site Experience.
During interventional and structural cardiology procedures, such as mitral valve (MitraClip, BMV), aortic valve (TAVR, BAV), tricuspid valve (MitraClip), left atrial appendage (Watchman, Lariat), atrial septum (ASD/PFO closure), and coronary artery intervention (high-risk PCI), among others, patients are at a high risk of hemodynamic instability and require continuous monitoring. This is conventionally achieved through arterial catheterization and transpulmonary thermodilution. However, such invasive techniques are time-consuming and have been associated with steep learning curves, vascular complications, and increased risk of infection. ⋯ In addition to AP and CO, the system provides up-to-date information on stroke volume (SV), stroke volume variation (SVV), and systemic vascular resistance, which can be useful in aiding decision-making and provide better postoperative outcomes, such as shorter length of stay (LOS), decreased postoperative infection, decreased postoperative arrhythmia, decreased postoperative renal failure, decreased postoperative congestive heart failure (CHF), and decreased readmission. Additionally, the simplicity of the system setup has translated into a time saving of up to 3 hours per day, allowing one team to perform an additional 2 to 3 valve interventions without moving rooms. Moving forward, a formal study comparing patient outcomes and cost-effectiveness between invasive and noninvasive hemodynamic monitoring techniques in valve replacement would be insightful.
