Transseptal puncture via a superior access as an alternative to the conventional femoral route

Radiofrequency puncture of the fossa ovalis for resistant transseptal access.

BACKGROUND Transseptal puncture with a conventional mechanical technique can fail because of a resistant interatrial septum. We evaluated the efficacy and safety of a new method to cross-resistant septae by transmitting radiofrequency (RF) energy through the transseptal needle. METHODS AND RESULTS Among 269 consecutive transseptal punctures, 13 (5%) were unsuccessful in 12 different patients ...

Modified Transseptal Puncture Technique in Challenging Septa: A Randomized Comparison to Conventional Technique

Background. Transseptal puncture (TSP) can be challenging. We compared safety and efficacy of a modified TSP technique ("mosquito" technique, MOSQ-TSP) to conventional TSP (CONV-TSP). Method. Patients undergoing AF ablation in whom first attempt of TSP did not result in left atrial (LA) pressure (failure to cross, FTC) were randomized to MOSQ-TSP (i.e., puncture of the fossa via a wafer-thin in...

Randomized Trial of Conventional Transseptal Needle Versus Radiofrequency Energy Needle Puncture for Left Atrial Access (the TRAVERSE‐LA Study)

BACKGROUND Transseptal puncture is a critical step in achieving left atrial (LA) access for a variety of cardiac procedures. Although the mechanical Brockenbrough needle has historically been used for this procedure, a needle employing radiofrequency (RF) energy has more recently been approved for clinical use. We sought to investigate the comparative effectiveness of an RF versus conventional ...
