Several scientific societies support performing left atrial appendage occlusion (LAAO) as a stand-alone procedure, even though it is often associated to other cardiomyopathies requiring transcatheter intervention. Though still controversial, combining LAAO and any other cardiac intervention might reduce hospitalizations, as well as the need for additional punctures, anesthesia, red tape, a longer stay and higher…
TCT 2023 | SWISS-APERO: One-Year Events After Left Atrial Appendage Closure with Amulet or Watchman FLX Device
It has been observed that the persistence of an opening in the left atrial appendage after percutaneous closure (LAAC) is associated with a higher risk of embolic events. Among the most commonly used devices for left atrial appendage closure are the Watchman FLX and Amulet devices. This study, known as SwissApero, represents the first randomized…
Left Atrial Appendage Closure: As Effective in Men and Women?
Atrial fibrillation is the most prevalent arrhythmia and to prevent its potential complications, we should administer anticoagulants (OACs), either warfarin or the new direct oral anticoagulants (DOACs). Even though these drugs have been shown effective, they still involve the risk of bleeding, especially gastrointestinal bleeding, which in turn leads to numerous hospitalizations. Left atrial appendage occlusion…
Do Men and Women Present the Same Evolution after Left Atrial Appendage Closure?
Atrial fibrillation is a very frequent type of arrythmia that affects both men and women alike. This entity is associated to higher mortality seeing as it favors stroke and hospitalization for cardiac failure. At present, one of its valid treatment strategies is left atrial appendage closure, to reduce or prevent stroke and anticoagulation driven bleeding. …
Left Atrial Appendage Closure Is a Valid Option
Atrial fibrillation (AF) is the most frequent arrhythmia in patients >55 years old and is related to ischemic stroke due to thrombi formation in the left atrium, particularly in the atrial appendage. To avoid this complication, anticoagulation is indicated, but patients >75 years are at high risk of bleeding, making percutaneous closure of the atrial…
Left Atrial Appendage Closure Is Safe with the New Devices
Left atrial appendage closure (LAAC) in non-valvular atrial fibrillation with high risk of bleeding has shown promising results with first generation devices (with the Watchman) in the different studies. At present, we have a more modern device, the Watchman FLX, but we do not have much information about it. To gather more data, researchers looked…
Peridevice Leak in Left Atrial Appendage Closure: more than one value to take into account
According to several registries, incomplete left atrial appendage (LAA) closure has been observed in up to 30% of cases after device implantation. The main cause of this complication is a mismatch between closure device and LAA ostium. The latter is elliptical in shape and varies in length, while the Watchman LAA closure device is round…
Antithrombotic Therapy Post Percutaneous Left Atrial Appendage Closure
Percutaneous left atrial appendage closure (LAAO) with Watchman has FDA approval since March 2015, having shown, in the PROTECT-AF and PREVAIL studies, reduced risk of atrial fibrillation driven stroke, by excluding the left atrial appendage form systemic circulation. Both studies used post procedure standardized protocols involving followup at 45 days and 6 months, imaging, and…

What things will I learn if I watch this video? 03:18 | Anatomical Bases for a Correct Transseptal Puncture.…
Left Atrial Appendage Closure: Effective to Reduce Risk of Stroke?
Original Title: Effectiveness of Left Atrial Appendage Exclusion Procedures to Reduce the Risk of Stroke: A Systematic Review of the Evidence. Reference: North Noelck et al. Circ Cardiovasc Qual Outcomes. July 2016. Published ahead of print. Atrial fibrillation is an important cause of stroke. Oral anticoagulation reduces the risk of stroke but, on the…
