Abstract
Dyspnea is a subjective sensation of difficult or uncomfortable breathing caused by increased excitation of brain respiratory centres,1 and is usually secondary to pulmonary or cardiac disease.2Heart failure is a serious public health problem in industrialised countries, with an increasing prevalence and incidence. It is more common in the elderly, and is usually caused by a defect in myocardial contraction, coronary atherosclerosis, or less frequently, valvular disease.3 Aortic insufficiency (AI) is one of them. It may originate from infective endocarditis, congenital or valvular heart disease, or rheumatic fever. It may lead to a medical emergency due to the inability of the left ventricle to adapt to the rapid increase in the end-diastolic volume caused by regurgitation of blood from aorta to left ventricle. If not corrected, the AI can lead to acute cardiogenic shock.4
