|Mraz et al. (2)||2007||30||RA||PLAATO|
|100%||NA||Procedural TEE in all patients. ICE only to guide transseptal puncture and positioning of the guide catheter|
|Berti et al. (3)||2014||121||RA, CS||ACP|
|96.7%||93.4%||Pre-procedural TEE. Procedural ICE & fluoroscopy. No follow-up TEE reported.|
|Masson et al. (4)||2015||37||LA (double transseptal)||ACP||97.3%||89.2%||Pre-procedural TEE. Procedural ICE & fluoroscopy. TEE at 3 months, only 3.3% leak.|
|Matsuo et al. (5)||2016||27||RA (or LA or LUPV)||Watchman||100%||96.3%||Pre-procedural TEE. Procedural ICE & fluoroscopy. TEE at 45 days, no flow 51.9%, <5-mm flow 48.1%.|
|Frangieh et al. (6)||2016||32||LA (single transseptal)||Watchman||100%||100.0%||Pre-procedural TEE. Procedural ICE & fluoroscopy. When compared to 44 TEE-guided cases, longer time to transseptal puncture and closure with ICE.|
|Korsholm et al. (7)||2017||109||LA (single transseptal)||ACP|
|99.1%||94.5%||Pre-procedural CTA. Procedural ICE & fluoroscopy. No difference in success and complication rates compared to TEE.|
The PLAATO (Percutaneous Left Atrial Appendage Transcatheter Occlusion) device is manufactured by ev3 Endovascular (North Plymouth, Minnesota), the ACP and Amulet are manufactured by Abbott Vascular (Minneapolis, Minnesota), and the WATCHMAN device is by Boston Scientific (Natick, Massachusetts).
ICE = intracardiac echocardiography; CS = coronary sinus; CTA = computed tomography angiography; LA = left atrium; LAA = left atrial appendage; LUPV = left upper pulmonary vein; NA = not available; RA = right atrium; TEE = transesophageal echocardiography.
