Coronary stenoses with low translesional gradient and abnormal coronary reserve: physiologic results after angioplasty.
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.
