title: Limitations of translesional pressure and flow velocity for long ostial left anterior descending stenoses.
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.
