Summary
Real-time three-dimensional transesophageal echocardiography (3D-TEE) identified a complex transseptal puncture during a Mitraclip procedure that two-dimensional TEE (2D-TEE) missed. This highlights 3D-TEE
Area of Science:
- Cardiovascular Imaging
- Interventional Cardiology
- Echocardiography
Background:
- Transseptal puncture is a critical step in various cardiac interventions, including Mitraclip procedures.
- Accurate visualization during transseptal puncture is essential for patient safety and procedural success.
- Limitations of two-dimensional imaging may exist in complex anatomical scenarios.
Observation:
- A case is presented where a complicated transseptal puncture occurred during a Mitraclip procedure.
- The complication was not detected using conventional two-dimensional transesophageal echocardiography (2D-TEE).
Findings:
- Real-time three-dimensional transesophageal echocardiography (3D-TEE) successfully identified the complex transseptal puncture.
- 3D-TEE provided crucial visualization that was absent in 2D-TEE images.
Implications:
- This case underscores the added value of 3D-TEE in real-time procedural guidance.
- 3D-TEE may improve safety and efficacy in transseptal puncture by detecting subtle complications.
- Enhanced imaging capabilities can potentially reduce procedural risks and improve patient outcomes.
