“…In addition, the Freestyle valve has the potential risk of causing structural abnormalities such as pseudoaneurysms due to inadequate tissue fixation with an immune response [ 25 ], or coronary artery stenosis from pseudo-intimal membranes [ 26 ]. Dagnegard et al [ 27 ] reported conducting four-dimensional CT on patients post-Freestyle valve implantation, frequently identifying such structural issues. Although the patient’s preoperative CT did not reveal a pseudoaneurysm or RCA stenosis, repeated PVEs and THV implantation may lead to such complications in the future.…”

Background Transcatheter valve replacement is contraindicated in patients with active infective endocarditis. However, few reports suggest that it could be beneficial for high-risk surgical patients with healed infective endocarditis. Here, we report a case of a surgical transcatheter aortic valve in a patient with healed repeated prosthetic valve endocarditis using a stentless valve. Case presentation A 79-year-old female who underwent the Bentall procedure using a stentless valve and coronary artery bypass grafting for annuloaortic ectasia 22 years ago was hospitalized for stage II bioprosthetic valve failure. The patient had a history of prosthetic valve endocarditis three times: the first and second prosthetic valve endocarditis occurred 15 years ago, and the third prosthetic valve endocarditis occurred 3 years ago. The causative organisms were Campylobacter fetus and Enterococcus faecalis. With appropriate antibiotic therapy, the lesion was localized and healed completely without valve destruction; however, the patient developed rapid aortic regurgitation. Based on a review of the patient’s history of prosthetic valve endocarditis, the absence of signs of infection, and clinical findings of transesophageal echocardiography and computed tomography, a diagnosis of structural valve deterioration with healed infective endocarditis was made. Subsequently, a transcatheter aortic valve in a surgical aortic valve using a balloon-expandable type was performed, because the patient had a high surgical risk of 12.7%. The patient’s postoperative course was uneventful. At the 1-year follow-up, there were no signs of infection or valve abnormalities. Conclusions Transcatheter valve replacement can be a treatment option for high-risk surgical patients with healed limited lesions in infective endocarditis.

“…Otherwise, the pseudoaneurysm formation can develop directly from the dissection of the weakened wall due to the infection and/or trauma or from the perforation of the abscess wall cavity 6 . In the context of previous cardiac surgery, new evidence suggests that the prevalence of silent pseudoaneurysm could be underestimated especially after aortic root replacement with a stentless graft 7,8 . Moreover the aforementioned triggering factors may facilitate the development of P‐MAIVF in susceptible young patients with CHD, including aortic coarctation, ventricular and atrial septal defect, patent ductus arteriosus, and BAV 8,9 .…”

Pseudoaneurysm of the mitral‐aortic intervalvular fibrosa (P‐MAIVF) can be a rare but life‐threatening complication of infective endocarditis, cardiac surgery, or blunt chest trauma. Congenital heart diseases especially in young patients are reported as additionally predisposing factors. We present the case of an asymptomatic 52 years‐old male with bicuspid aortic valve and gastrointestinal polyposis syndrome in whom a P‐MAIVF was incidentally detected. The patient successfully underwent pseudoaneurysm surgical repair and aortic valve replacement and despite no evident causes were found we hypothesized addiotional underlying mechanism of P‐MAIVF.
