Abstract
Access to the left atrium for LAA closure has been standardized to optimize the entry to the LAA and limit complications. Following femoral vein access, transseptal crossing from the right atrium to the left atrium in an inferior and posterior location of the Fossa ovalis has proven to be a key factor to a straightforward device positioning and release. This is best achieved with a Brockenbrough needle delivered to the Fossa ovalis through a SL1 sheath stabilized with a dilator. TEE guiding for transseptal puncture is used by most operators and highly recommended to avoid complications and optimize access.
