Interest in transseptal puncture has surged with the development of structural interventions for the left side of the heart. Francesco Maisano provides an update on its changing role in modern interventional cardiology.

The transseptal puncture (TP) technique was developed in the 1950s by Ross et al as a diagnostic tool to investigate patient haemodynamics before cardiac surgery. However, as Doppler echocardiography became established as the main method of interpreting haemodynamics, diagnostic applications were rapidly abandoned, and transseptal puncture was no longer used much by most interventional cardiologists, although electrophysiologists continued to routinely perform it for atrial fibrillation ablation.

The advent of left-sided catheter-based therapies, and the introduction into clinical practice of several left heart structural interventions, has reawakened an interest in learning and retraining in transseptal puncture. Tra...
