Insights
Assessing coronary lesions with pressure and flow velocity is crucial for intermediate or indeterminate cases. However, complex lesions and certain patient conditions may limit the effectiveness of these measurements alone.
Area of Science:
- Cardiovascular medicine
- Interventional cardiology
- Physiology
Background:
- Translesional pressure and flow velocity are key hemodynamic parameters.
- Intermediate or indeterminate coronary lesions require accurate assessment for intervention.
- Ostial narrowings and long lesions present unique challenges in lesion evaluation.
Abstract:
Translesional pressure and flow velocity can be used to assess angiographically intermediate or indeterminate lesions. Ostial narrowings and long lesions represent situations that may require both pressure and flow velocity assessment. In patients with hypertension, diabetes mellitus, and chronic renal failure, distally measured absolute and regional coronary reserve values alone may not be helpful in selecting lesions requiring intervention.
