Insights

Atrial fibrillation (AF) increases stroke risk, often due to clots in the left atrial appendage (LAA). Transcatheter LAA closure is a new method to prevent these strokes.

Area of Science:

  • Cardiology
  • Vascular Medicine
  • Interventional Cardiology

Background:

  • Atrial fibrillation (AF) is a common arrhythmia.
  • AF significantly elevates stroke risk, primarily due to thrombi formation.
  • Thrombi in non-valvular AF are predominantly located in the left atrial appendage (LAA).

Purpose of the Study:

  • To review recent advancements in transcatheter LAA closure.
  • To discuss the role of LAA closure in preventing thromboembolism for AF patients.
  • To identify potential challenges associated with LAA closure procedures.

Main Methods:

  • Literature review of transcatheter LAA closure techniques.
  • Analysis of clinical data and outcomes related to LAA closure.
  • Discussion of current challenges and future directions in LAA closure therapy.

Main Results:

  • Transcatheter LAA closure has emerged as a significant therapeutic option over the past decade.
  • This approach targets the primary source of emboli in non-valvular AF.
  • Evidence supports LAA closure as an effective stroke risk reduction strategy.

Conclusions:

  • Transcatheter LAA closure is a promising intervention for thromboembolism prevention in AF.
  • Continued research and technological advancements are crucial.
  • Addressing current challenges will optimize patient outcomes and expand therapeutic applications.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
