Emerging applications for transseptal left heart catheterization old techniques for new procedures

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Cardiac Catheterization

Background:

• Transseptal (TS) catheterization, introduced in 1959, was initially used for direct left atrial (LA) pressure measurement.
• Its diagnostic use has declined, replaced by indirect methods like the Swan-Ganz catheter, leading to a loss of expertise.
• However, TS puncture remains crucial for specific interventions like balloon valvuloplasty and arrhythmia ablation.

Purpose of the Study:

• To highlight the resurgence of interest in the transseptal catheterization technique.
• To emphasize the need for invasive cardiologists to update their skills in TS puncture.
• To underscore the importance of advanced imaging in guiding modern TS procedures.

Main Methods:

• Review of the historical and current applications of transseptal catheterization.
• Discussion of emerging therapeutic procedures necessitating TS access.
• Emphasis on the role of contemporary ultrasound imaging and devices in TS guidance.

Main Results:

• Transseptal catheterization is experiencing a revival due to novel structural heart disease interventions and atrial fibrillation ablation.
• Expertise in the traditional TS puncture technique has diminished in many centers.
• Newer TS devices and advanced ultrasound guidance are becoming integral to the procedure.

Conclusions:

• Invasive cardiologists require re-familiarization with transseptal catheterization techniques.
• Mastery of TS puncture is essential for upcoming therapeutic cardiac interventions.
• Integration of advanced imaging and updated devices is critical for successful TS procedures.
