Review
Aortic regurgitation (AR) has an estimated prevalence of 4.9% in the Framingham study, with moderate or severe AR occurring in 0.5% of the study population. The incidence and severity of AR increases with age, and may occur acutely or as a chronic valvular disease with distinct presentations, natural history and management strategy. Our review is a comprehensive description of the varied presentation of aortic regurgitation and its management.

A 1-month-old crossbred calf was referred for examination due to marked systolic heart murmurs and poor growth. The heart murmur was most audible on the right side of the cranial thorax. Cardiomegaly was evident on chest radiography, and echocardiography demonstrated aortic regurgitation and decreased fractional shortening. Cardiomegaly, aortic root dilation and cardiac displacement were confirmed by computed tomography. At necropsy, the heart was enlarged, and all three aortic valve leaflets were irregularly shaped. In calves with chronic aortic insufficiency, remodeling displacement of the heart and aorta causes changes in the location and timing of heart murmurs. Therefore, aortic insufficiency cannot be ruled out when a systolic heart murmur can be observed in the right chest wall.

Review
There is a paucity of studies looking at the natural history of valvular heart disease (VHD) in exercising individuals, and exercise recommendations are largely based on expert consensus. All individuals with VHD should be encouraged to avoid sedentary behaviour by engaging in at least 150 min of physical activity every week, including strength training. There are generally no exercise restrictions to individuals with mild VHD. Regurgitant lesions are better tolerated compared with stenotic lesions and as such the recommendations are more permissive for moderate-to-severe regurgitant VHD. Individuals with severe aortic regurgitation can still partake in moderate-intensity exercise provided the left ventricle (LV) and aorta are not significantly dilated and the ejection fraction (EF) remains >50%. Similarly, individuals with severe mitral regurgitation can partake in moderate-intensity exercise if the LV end-diastolic diameter <60 mm, the EF ≥60%, resting pulmonary artery pressure <50 mm Hg and there is an absence of arrhythmias on exercise testing. Conversely, individuals with severe aortic or mitral stenosis are advised to partake in low-intensity exercise. For individuals with bicuspid aortic valve, in the absence of aortopathy, the guidance for tricuspid aortic valve dysfunction applies. Mitral valve prolapse has several clinical, ECG and cardiac imaging markers of increased arrhythmic risk; and if any are present, individuals should refrain from high-intensity exercise.

A 56-year-old man presented with typical angina for 1 day and a prior history of exertional dyspnea of 6 months duration. Clinically, he was diagnosed with severe aortic regurgitation (AR). Electrocardiogram showed left ventricular hypertrophy with volume overload.
