Key result
The Konno procedure was successfully used to debride and reconstruct an interventricular septal abscess in a patient with infective endocarditis, allowing for uneventful discharge 29 days post-surgery.
Why the study?
Annular abscess is a serious complication of infective endocarditis with high postoperative mortality, and the Konno procedure may provide surgical access and reconstruction for abscesses extending into the interventricular septum.
Can the Konno procedure be successfully used for debridement and reconstruction in an adult with aortic valve infective endocarditis and an annular abscess extending into the interventricular septum?

Can the Konno procedure be successfully used for debridement and reconstruction in an adult with aortic valve infective endocarditis and an annular abscess extending into the interventricular septum?
The Konno procedure can be a viable surgical option for adults with complex aortic valve infective endocarditis involving an annular abscess extending into the interventricular septum.
May warrant consideration in select aortic IE cases with abscess; extends adult Konno experience but leaves open need for validation.
Annular abscess is a serious complication of infective endocarditis, which often requires complex surgery and has a very high post-operative mortality rate. The Konno procedure involves valve annuloplasty for a narrow aortic annulus or left ventricular outflow tract stenosis in children; it is also performed for various cardiac conditions in adults. Here, we report a case of the Konno procedure performed in a patient with aortic valve infective endocarditis, with an annular abscess extending into the interventricular septum (IVS). A 58-year-old man who presented to our hospital with fever was diagnosed with aortic valve infective endocarditis caused by Streptococcus saccharolyticus. On echocardiography, an annular abscess in the direction of the IVS was detected, and surgery was planned. The Konno procedure was performed to secure an adequate surgical field and to debride and reconstruct the cavity created by the interventricular septal abscess. The patient was discharged uneventfully 29 days after surgery.

Doi et al. (2021) conducted a case report in Aortic valve infective endocarditis with annular abscess (n=1). Konno procedure was evaluated on Surgical success and discharge. The Konno procedure was successfully used to debride and reconstruct an interventricular septal abscess in a patient with infective endocarditis, allowing for uneventful discharge 29 days post-surgery.
