He had undergone aortic valve replacement with mechanical prosthesis for severe aortic stenosis due to bicuspid aortic valve at the age of 25. Clinical examination showed a normal jugular pulse, absence of cardiomegaly, normal prosthetic valve clicks, grade 3 ejection systolic murmur in the right second parasternal space, and non-tender hepatosplenomegaly. Labortory examination showed hemoglobin – 15.9 g/dl and a total count of 4900 cells/mm 3 with a differential count of 49% polymorphs and 48% lymphocytes. Electrocardiogram showed a normal sinus rhythm with a PR interval of 150 ms. Echocardiography, transthoracic (Fig.  1a, Video  1), transesophageal (Fig.  1b, Video  2), and 3D (Fig.  1c, d, Video  3), revealed multiloculated aortic root abscess encircling the prosthetic valve.
