The present study reports a case of a 64-year-old man was admitted for sudden collapse. On auscultation, new grade 4/6 continuous murmur were detected and was best heard along the right sternal border. Blood culture yielded Staphylococcus haemolyticus and Escherichia coli. Despite appropriate antibiotic treatment, the patient’s condition deteriorated and he developed multiple organ failure. Transesophageal echocardiography revealed echofree spaces with periannular abscess, and two perforations at the noncoronary sinus of Valsalva aneurysms. This case was about an unusual case of prosthetic aortic valve infectious endocarditis with periannular abscess formation and noncoronary sinus of Valsalva aneurysms rupturing into the right atrium and right ventricle.
