Summary
Transcatheter edge-to-edge repair (TEER) utilization significantly increased among Medicare patients from 2015-2019. Operator procedural volumes also grew, but geographic variability in TEER use persists.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Health Services Research
Background:
- Operator experience is linked to procedural success in transcatheter edge-to-edge repair (TEER).
- Contemporary utilization and procedural volumes for TEER remain incompletely understood.
- Understanding trends is crucial for optimizing patient outcomes and access to care.
Purpose of the Study:
- To identify annual operator procedural volumes for TEER.
- To analyze temporal trends in TEER utilization.
- To examine geographic variability in TEER among US Medicare patients.
Main Methods:
- Utilized the National Medicare Provider Utilization and Payment Database.
- Analyzed data for CPT code 33418 (MitraClip) from 2015 to 2019.
- Assessed annual operator procedural volumes, incidence, and longitudinal/geographic trends.
Main Results:
- 27,034 TEER procedures were performed between 2015-2019.
- Nationwide TEER incidence rose 283% (6.2 to 23.8 per 100,000 patients).
- Significant state-level variability in TEER incidence (5.5 to 54.9 per 100,000) and mean annual operator volume (9.1 procedures in 2019) were observed.
Conclusions:
- TEER utilization and operator procedural volumes significantly increased from 2015-2019.
- Considerable geographic variability in TEER utilization exists across US states.
- Further research is needed to understand the clinical impact of this variability and determine optimal procedural volumes for efficacy and access.

01:16Conservation of Mass in Finite Cotrol Volume
The principle of conservation of mass is a fundamental law in fluid mechanics and is applied using the continuity equation. We apply the concept to a finite control volume to derive the continuity equation.
A system is defined as a collection of unchanging contents, and the conservation of mass states that a system's mass is constant.

01:07Conservation of Mass in Fixed, Nondeforming Control Volume
The principle of conservation of mass is fundamental in fluid dynamics and is crucial for analyzing flow within fixed control volumes, such as pipes or ducts. This principle states that the total mass within a control volume remains constant unless altered by the inflow or outflow of mass through the control surfaces. This results in a vital relationship for steady, incompressible flow where the mass entering a system equals the mass leaving it.

01:15Application of the Linear Momentum Equation
The application of the linear momentum equation can be used to analyze the forces needed to hold a 180-degree pipe bend in place with flowing water. In this case, water flows through the bend with a constant cross-sectional area of 0.01 square meters and a flow velocity of 15 meters per second. The pressure at the entrance is 0.2 Megapascals and the pressure at the exit is 0.16 Megapascals.

01:28Major Losses in Pipes
When a fluid flows through a pipe, it experiences energy losses due to frictional resistance along the pipe walls, known as major losses. These energy losses result in a pressure drop, which varies based on the flow conditions — whether laminar or turbulent — and the specific physical properties of the fluid and pipe.
Fluid flow can be classified as laminar or turbulent, primarily based on the Reynolds number. This dimensionless number reflects the relative influence of inertial to viscous...

01:25Minor Losses in Pipes
In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively.
Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...

01:28Pipe Flowrate Measurement
In pipe flow measurement, orifice, nozzle, and Venturi meters are commonly used to determine fluid flowrates by constricting the flow area, which increases fluid velocity and reduces pressure. This pressure difference, governed by Bernoulli's principle and adjusted for real-world conditions, is essential for calculating flowrate. Each meter type is suited to specific applications based on accuracy, efficiency, and compatibility with various flow conditions.
