Insights
Clinically significant coronary stenoses with low pressure gradients pose treatment challenges. Physiologic assessment helps determine if intervention is needed or if deferral is safe for these moderate lesions.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Physiology
Background:
- Clinically significant coronary artery stenoses with moderate angiographic appearance present therapeutic dilemmas.
- Lesions with low translesional pressure gradients and reduced coronary flow reserve are particularly challenging.
- Accurate risk stratification is crucial for optimizing treatment strategies in these cases.
Abstract:
Clinically active but angiographically moderate coronary stenoses present a difficult problem for intervention, especially when such lesions have a low translesional pressure gradient and impaired coronary reserve. Physiologic data suggest some lesions can be safely deferred, whereas others may benefit from immediate intervention.
