Facilitation techniques to cross the interatrial septum with intracardiac echocardiography during left atrial appendage closure.

ABSTRACT:

Objectives

This study aimed to assess the rate of difficult interatrial septum (IAS) crossing with the intracardiac echocardiography (ICE) probe during percutaneous left atrial appendage (LAA) closure and to identify techniques that facilitate IAS crossing with the ICE probe.

Background

Percutaneous LAA closure is increasingly performed by ICE guidance. Although such an approach omits the need for general anesthesia, crossing of the IAS with the ICE probe may sometimes be challenging.

Methods

All consecutive patients that underwent ICE-guided percutaneous LAA closure with an Amplatzer Amulet (Abbott) or WatchmanFLX (Boston Scientific) at our center in the period 2018-2021 were included. Cases in which IAS crossing with ICE was difficult were identified and techniques
