Direct Implant of a Transcatheter Aortic Valve Prosthesis for Prosthetic Mitral Valve Endocarditis.

ABSTRACT: We describe the case of a 64-year-old woman presenting with severe prosthetic mitral valve endocarditis 1 year after coronary artery bypass grafting and double valve replacement. Echocardiogram revealed high-pressure gradients through the bioprosthetic MV with a bulky vegetation. As the patient had presented operative difficulties due to severe mitral annular calcification, was in renal failure, and in the absence of any perivalvular involvement, an open-heart surgical catheter-based valve implantation was successfully performed after removal of the infected leaflets, leaving the stent frame and sewing cuff behind. Albeit controversial, this case represents an alternative approach for select high-risk reoperative mitral cases with mitral annular calcification.

Successful surgical aortic valve replacement for prosthetic valve infective endocarditis following transcatheter aortic valve implantation.

Project description:An 80-year-old male underwent a transcatheter aortic valve implantation (TAVI) for severe senile aortic stenosis. Six weeks after the surgery, he was readmitted to our institution because of a high-grade fever. Transesophageal echocardiography revealed thickening of all three leaflets of the aortic prosthesis and mobile mass on the leaflet, and Streptococcus sanguis was identified from his blood culture. Therefore, he was diagnosed with prosthetic valve endocarditis (PVE) and received intensive intravenous antibiotic therapy. Because he did not respond to the pharmacological therapy, surgical aortic valve replacement (AVR) was indicated although it was considered a relatively high-risk procedure. Herein, we report on the successful surgical AVR in this patient using a pericardial valve after removal of the infected prosthetic valve, and discuss some issues related to this rare complication after TAVI. <Learning objective: Transcatheter aortic valve implantation (TAVI) is a highly effective procedure for patients with symptomatic severe aortic stenosis who are at high risk or deemed inoperable. Because it only requires limited surgical invasiveness, the risk of prosthetic valve endocarditis (PVE) after TAVI is thought to be low. However, PVE can occur even early after TAVI. We present our recent such case and discuss some issues related to this rare complication.>.

Transcatheter Aortic Valve Replacement as a Rescue Treatment for Prosthetic Valve Endocarditis.

Project description:A 74-year-old man with a history of bioprosthetic aortic valve replacement presented with acute severe aortic insufficiency and cardiogenic shock secondary to Diphtheroides and Enterococcus endocarditis. The patient was deemed to be not a surgical candidate by the multidisciplinary team and underwent rescue transcatheter aortic valve-in-valve replacement, resulting in complete recovery. (Level of Difficulty: Advanced.).

Case Report: Leaflet thrombosis after transcatheter valve-in-valve aortic valve replacement in prosthetic valve endocarditis.

Project description:A 70-year-old female patient with a history of bioprosthetic aortic valve replacement and coronary artery bypass graft presented with bioprosthetic valve failure secondary to prosthetic valve endocarditis. The patient was deemed unsuitable for surgery by the heart team, following which she underwent transcatheter aortic valve-in-valve replacement. This resulted in early death due to myocardial infarction and acute heart failure. A computed tomography revealed subclinical leaflet thrombosis. This case highlights the importance of postoperative anticoagulation therapy.

Transcatheter, valve-in-valve transapical aortic and mitral valve implantation, in a high risk patient with aortic and mitral prosthetic valve stenoses.

Project description:Transcatheter valve implantation continues to grow worldwide and has been used principally for the nonsurgical management of native aortic valvular disease-as a potentially less invasive method of valve replacement in high-risk and inoperable patients with severe aortic valve stenosis. Given the burden of valvular heart disease in the general population and the increasing numbers of patients who have had previous valve operations, we are now seeing a growing number of high-risk patients presenting with prosthetic valve stenosis, who are not potential surgical candidates. For this high-risk subset transcatheter valve delivery may be the only option. Here, we present an inoperable patient with severe, prosthetic valve aortic and mitral stenosis who was successfully treated with a trans catheter based approach, with a valve-in-valve implantation procedure of both aortic and mitral valves.

Transcatheter Aortic Valve Replacement for Aortic Stenosis With Prosthetic Mitral Paravalvular Leak and Hemolytic Anemia.

Project description:This report describes a successful transcatheter aortic valve replacement in an older patient with severe aortic stenosis, mitral paravalvular leak, and associated hemolytic anemia. Transcatheter aortic valve replacement is worth considering as a first-line procedure in this high-risk patient because of its beneficial impact on reducing shear forces at the mitral valve. (Level of Difficulty: Intermediate.).

Prosthetic valve endocarditis secondary to <i>Corynebacterium</i> following transcatheter aortic valve implantation: a case report.

Project description:BackgroundTranscatheter aortic valve implantation (TAVI) has emerged as an alternative for the treatment of severe symptomatic aortic stenosis for patients at high risk for open surgery. Although experience with TAVI is increasing, few cases of post-TAVI endocarditis are reported.Case summaryWe present a case of an 87-year-old female patient who presented with fever, unresponsive to empiric antibiotics 3 months after a TAVI procedure for severe aortic valve stenosis. After some delay due to three hospitalizations in primary care hospitals, she was transferred to our general intensive care unit where the diagnosis of endocarditis due to Corynebacterium was made. The patient was transferred abroad to a specialized surgical centre of excellence and underwent aortic root and valve replacement with a homograft. After several post-operative complications the patient's condition improved and is presently satisfactory.DiscussionKeeping a high index of suspicion when evaluating patients might lead to a favourable outcome if appropriate and early intervention was implemented. Adherence to policies which address infection control and aseptic techniques when performing TAVI might lead to fewer cases of post-TAVI endocarditis.
