We present a case of a very rare isolated coronary lesion secondary to TA.

In the majority of patients, stenosis severity is easily identified by a low valve area and high mean gradient. However, a subset of patients are found to have a low mean gradient despite a low valve area. These latter types can present as either low ejection fraction (EF) with low gradient (stage D2) or normal EF with low gradient (stage D3). Stage D3 is especially difficult to accurately diagnose.
Severe aortic stenosis (AS) is typically identified by a low valve area (≤1.0 cm2) and high mean ... more Severe aortic stenosis (AS) is typically identified by a low valve area (≤1.0 cm2) and high mean gradient (≥40 mmHg). A subset of patients are found to have a less than severe mean gradient (<40 mmHg) despite a low valve area. These latter types can present as either low ejection fraction with low-gradient AS (stage D2) or normal ejection fraction with low-gradient AS (stage D3). Determining the true severity of disease within these categories has proved difficult. In this review we illustrate both traditional and novel techniques that can be used for further valvular assessment. We also propose a simple algorithm that can be used to evaluate low-gradient AS.
