VEGA, Julián et al. Acute severe aortic regurgitacion echocardiography features: Clinical case and review. Rev Chil Cardiol [online]. 2018, vol.37, n.3, pp.206-211. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602018000300206.

Severe acute aortic regurgitation (SAAR) constitutes a surgical emergency. Its main causes are infective endocarditis and aortic dissection. Three echocardiographic hallmarks aid in its diagnosis and management, namely: premature opening of the aortic valve (POAV), premature mitral valve closure (PMVC) and diastolic mitral regurgitation (DMR), findings that reflect the great increase in left ventricular end-diastolic pressure. Also, these findings are distinctive but not unique to SAAR. We report a 36-year-old male, without past medical history that refers three weeks of malaise, fever and heart failure. At the emergency department, the patient evolved to cardiogenic shock being admitted to the coronary unit. A transthoracic and transesophageal echocardiography revealed a severely dilated left ventricle with normal systolic function, a mild left atrium enlargement and endocarditis of a trileaflet aortic valve with severe regurgitation. Furthermore, PMVC and DMR were identified, findings that portrayed the severe and acute presentation of the disease. A surgical aortic valve replacement was performed uneventfully, and the patient discharged in good conditions.
