[The frequency of systolic aortic regurgitation and its relationship to heart failure in a consecutive series of patients].

Although aortic regurgitation is a diastolic phenomenon, it has been observed during systole in a few cases. Our aims were to determine the incidence of systolic aortic regurgitation in routine clinical practice and to investigate the clinical profiles of patients with the condition. An exhaustive prospective study of all investigations performed by a hospital echocardiographic unit over one month was carried out. Systolic aortic regurgitation was detected in five out of a total of 216 investigations (2.3%). In all cases, the patient had some degree of heart failure. Overall, the condition was present in 5.9% of patients with heart failure. In one patient with atrial fibrillation, systolic aortic regurgitation disappeared and the patient's clinical status improved after atrioventricular node modulation using a cryoablation catheter. Systolic aortic regurgitation was not an exceptional occurrence in hospitalized patients. Moreover, it tended to be specifically associated with heart failure.
