[Cardiopathies associated with a low embolic risk]

Area of Science:

• Cardiology and Neurology
• Cardiovascular Imaging
• Cerebrovascular Disease

Context:

• Advancements in cardiac imaging identify potential cardioembolic sources (e.g., patent foramen ovale, atrial septal aneurysm, cardiac strands, mitral valve prolapse).
• A significant prevalence of these cardiac findings exists in individuals without a history of stroke.
• The etiological role of these cardiac abnormalities in stroke causation remains unclear.

Purpose:

• To investigate the association between cardiac abnormalities and stroke.
• To determine if identified cardiac findings are causative or incidental in stroke patients.
• To define risk stratification and therapeutic intervention benefits for stroke associated with cardiac abnormalities.

Summary:

• Cardiac imaging frequently detects abnormalities like patent foramen ovale, but their causal link to stroke is often ambiguous, especially given their prevalence in stroke-free individuals.
• These cardiopathies are generally associated with a low stroke risk.
• Further studies are essential to elucidate stroke risk, underlying mechanisms, identify high-risk patients, and evaluate treatment efficacy.

Impact:

• Clarifying the role of cardiac abnormalities in stroke will enable precise patient selection for interventions.
• Avoiding unnecessary treatments reduces patient exposure to potential therapeutic complications.
• Improved understanding facilitates evidence-based guidelines for managing cardioembolic stroke.
