Physical examination revealed an active, eupneic, afebrile, acyanotic, anicteric patient with pink and moist mucous membranes and without jugular distension. Pulmonary auscultation revealed no abnormalities in either lung field. Cardiomegaly was absent and cardiac rhythm was regular with normal heart sounds, but an early-mid-diastolic respiratory murmur was present over the aortic area (2+/6+). Blood pressure was 140/60 mmHg and heart rate was 76 bpm.</p><p id="par0020" class="elsevierStylePara elsevierViewall">A conventional resting electrocardiogram showed sinus rhythm, heart rate of 78 bpm and left ventricular overload.

A resting Doppler echocardiogram revealed aortic regurgitation, defined as moderate based on the slope of the deceleration curve in diastole (slope 354 cm/s<span class="elsevierStyleSup">2</span>) and no holodiastolic retrograde blood flow in the abdominal aorta (score 6). The eccentricity of the regurgitant jet limited the possibility of using the width and area of the aortic regurgitation jet as parameters to classify the severity of the valvulopathy (<a class="elsevierStyleCrossRef" href="#fig0005">Figure 1</a>A). There was eccentric LV hypertrophy but no signs suggestive of pulmonary arterial hypertension. The following chamber diameters and volumes were calculated: left atrial diameter 38 mm, end-diastolic LV diameter 64 mm, end-systolic LV diameter 42 mm, end-diastolic LV volume 142 ml, and end-systolic LV volume 57 ml.

The patient's heart rate showed a physiological behavior during exercise, starting at a resting heart rate of 78 bpm and reaching 141 bpm at peak exercise (87% of maximum predicted heart rate). Similarly, the behavior of blood pressure during the test was normal, starting exercise at a resting blood pressure of 130/70 mmHg and reaching 175/70 mmHg at peak exercise.
