AI Article Synopsis

  • Advances in interventional cardiology have led to increased use of cardiac devices, resulting in more cases of device-associated endocarditis, a serious condition with complex treatment challenges.
  • The case of an 83-year-old woman illustrates the risks, as she developed endocarditis linked to her left atrial appendage closure device 20 months post-procedure, leading to her eventual death despite antibiotic treatment.
  • The report highlights the rarity of LAA closure device-associated endocarditis but notes that as these devices become more common, healthcare professionals should anticipate an increase in such infections, emphasizing the need for accurate diagnostic methods like transoesophageal echocardiography.

Article Abstract

Background: Due to advances in interventional cardiology in recent years, more and more patients are currently receiving cardiac devices, with a subsequent increase in the number of patients with device-associated endocarditis. Device-associated endocarditis is a life-threatening disease with special diagnostic and therapeutic challenges. Interventional devices for left atrial appendage (LAA) closure have been available for several years. However, there have been very few case reports of LAA closure device-associated endocarditis.

Case Summary: An 83-year-old woman presented with fever and fatigue. She had a history of permanent atrial fibrillation and recurrent bleeding on oral anticoagulation. Consequently, the patient underwent interventional LAA closure ∼20 months earlier. Blood cultures grew . Transoesophageal echocardiography revealed an LAA closure device-associated mobile, echo-dense mass that was consistent with infectious vegetation in this clinical context. Intravenous antibiotic therapy was started, and our heart team recommended complete removal of the device, which the patient refused. The patient subsequently died as a result of progressive endocarditis and multiple pre-existing co-morbidities.

Discussion: Left atrial appendage occlusion device-associated endocarditis has rarely been reported. Due to the increase in LAA closure device implantation, device-associated endocarditis is expected to increase in the future. Transoesophageal echocardiography is required for correct diagnosis. Our case report suggests that an infection can occur long after implantation.

Background: Either dual antiplatelet therapy or oral anticoagulation in combination with aspirin represent recommended treatment regimens following left atrial appendage closure (LAAC). As the majority of patients receiving LAAC have high bleeding risk, less aggressive antithrombotic treatments are needed, such as single antiplatelet therapy.

Objectives: To compare both ischemic and bleeding outcomes in patients receiving single (SAPT) or dual antiplatelet therapy (DAPT) after successful LAAC.

The main objective of this study was to investigate the optimal post-left atrial appendage closure (LAAC) anticoagulation strategy, focusing on minimizing device-related thrombosis (DRT) and thromboembolism (TE) events without increasing bleeding risk. After successful LAAC, consecutive participants were treated with 45-day anticoagulants (rivaroxaban 15 mg daily, dabigatran 110 mg twice a day, and warfarin). The efficacy endpoints included DRT, TE, and hospital readmissions due to cardiac caused, while safety endpoints encompassed bleeding events, monitored over a 12-month follow-up period.

Article Synopsis
  • Left atrial appendage closure (LAAC) is an alternative for patients with nonvalvular atrial fibrillation (NVAF) to avoid oral anticoagulants, but issues like incomplete device endothelialization (IDE) can lead to complications.
  • A study compared the endothelialization rates after implantation of two devices: the Watchman plug and the LACBES occluder, in 201 patients, using cardiac computed tomography angiography (CCTA).
  • Results showed that the LACBES occluder had a higher IDE rate at both 3 and 6 months compared to the Watchman device, indicating that it takes longer for the LACBES to achieve complete endothelialization after LAAC.

Background: The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease-of-use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control group of LAAC employing the standard sheath.

Methods: The first n = 32 consecutively treated patients at our site using the Amulet device with the Steerable Delivery Sheath were included in this retrospective analysis.
