Official Description

Insertion of left atrial hemodynamic monitor; pressure sensor lead at time of insertion of pacing cardioverter-defibrillator pulse generator including radiological supervision and interpretation and associated injection procedures, when performed (List separately in addition to code for primary procedure)

Common Language Description

The CPT® Code 0294T refers to the procedure involving the insertion of a left atrial hemodynamic monitor, specifically a pressure sensor lead, during the implantation of a pacing cardioverter-defibrillator pulse generator. This procedure is crucial for patients suffering from heart failure, as it allows for the continuous monitoring of left atrial pressure (LAP). The ability to accurately measure cardiac hemodynamics is essential for managing fluid status in patients experiencing acute decompensation of heart failure. The left atrial hemodynamic monitor device is designed to provide real-time data on LAP, temperature, and intracardiac electrograms, which can significantly aid in clinical decision-making. The device comprises an implantable sensor lead, a subcutaneous antenna coil, and a sealed sensor module that contains a pressure-sensing membrane and the necessary circuitry for data transmission. This procedure can be performed as a standalone intervention or in conjunction with other cardiac devices, such as an implantable cardioverter defibrillator (ICD) or a cardiac resynchronization therapy defibrillator (CRT-D). The insertion process involves advanced techniques, including the Seldinger technique for sheath placement and fluoroscopic guidance for accurate sensor placement, ensuring optimal monitoring capabilities for the patient.

1. Indications

The insertion of a left atrial hemodynamic monitor is indicated for patients with heart failure, particularly those experiencing acute decompensation. The procedure is performed to facilitate the continuous monitoring of left atrial pressure (LAP), which is critical for managing fluid status in these patients. The ability to track hemodynamic changes can help guide treatment decisions and improve patient outcomes.

  • Heart Failure Patients with heart failure, especially during acute decompensation, require monitoring of left atrial pressure to manage fluid status effectively.

2. Procedure

The procedure for the insertion of a left atrial hemodynamic monitor involves several critical steps to ensure proper placement and functionality of the device.

  • Step 1: Preparation and Access The procedure begins with the patient being positioned appropriately, and local anesthesia is administered. The Seldinger technique is utilized to access the right femoral vein, where sheaths are placed to facilitate catheter insertion.
  • Step 2: Transseptal Puncture Following sheath placement, a transseptal puncture is performed to access the left atrium. This step is crucial for the successful implantation of the sensor lead.
  • Step 3: Heparin Administration After the transseptal puncture, heparin is administered at a dosage of 5000 IU to prevent clot formation during the procedure.
  • Step 4: Delivery Sheath Placement A delivery sheath is then placed into the left atrium, providing a pathway for the sensor lead to be advanced into position.
  • Step 5: Sensor Lead Implantation The sensor lead is advanced under fluoroscopic guidance until the distal anchor unfolds and makes contact with the left side of the atrial septum, ensuring proper placement for accurate pressure monitoring.
  • Step 6: Antenna Coil Placement Once the sensor lead is securely positioned, the antenna coil is connected to the proximal end of the sensor lead and placed in a subcutaneous pocket, completing the implantation process.

3. Post-Procedure

After the insertion of the left atrial hemodynamic monitor, patients are typically monitored for any immediate complications related to the procedure. This includes observing for signs of bleeding, infection, or device malfunction. Patients may require follow-up imaging to confirm the proper placement of the device and to assess its functionality. Additionally, ongoing monitoring of the patient's hemodynamic status will be necessary to ensure that the device is providing accurate readings and to guide further treatment decisions.
