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.>.

Successful Management of Myval Transcatheter Heart Valve Embolization Into Abdominal Aortic Aneurysm During Transcatheter Aortic Valve Replacement.

Project description:Transcatheter heart valve embolization is a serious and rare complication of transcatheter aortic valve replacement. Having a strategy for promptly managing transcatheter heart valve embolization is crucial to avoid emergency conversion from transcatheter aortic valve replacement to open-heart surgery. Many cases of transcatheter heart valve embolization occurring with balloon-expandable prostheses such as the SAPIEN 3 (Edwards LifeSciences Corporation) valve and self-expandable prostheses such as the ACURATE neo (Boston Scientific Corporation) valve have been reported in the literature. Here, for the first time (to the authors' knowledge), the case of a Myval (Meril Life Sciences Pvt Ltd) transcatheter heart valve embolization during transcatheter aortic valve replacement, which was treated percutaneously with favorable outcomes, is reported.

Successful redo aortic valve replacement using Perceval for multiple recurrent prosthetic valve dysfunction.

Project description:A 50-year-old man who required aortic valve replacement (AVR) 3 times for severe paravalvular leakage (PVL) was diagnosed with a recurrence of severe PVL. Since the PVL recurred each time because of prosthetic valve detachment from the annulus, a fourth AVR was performed using a self-expanding sutureless valve. Postoperative echocardiography showed no significant PVL. The patient was discharged without any complications and returned to normal work soon after. In cases such as our patient, sutureless AVR could be a powerful alternative to conventional AVR.

Aortic valve cusp repair does not affect durability of modified aortic valve reimplantation for tricuspid aortic valves.

Project description:ObjectiveDuring aortic valve reimplantation, cusp repair may be needed to produce a competent valve. We investigated whether the need for aortic valve cusp repair affects aortic valve reimplantation durability.MethodsPatients with tricuspid aortic valves who underwent aortic valve reimplantation from January 2002 to January 2020 at a single center were retrospectively analyzed. Propensity matching was used to compare outcomes between patients who did and did not require aortic valve cusp repair.ResultsCusp repair was performed in 181 of 756 patients (24%). Patients who required cusp repair were more often male, were older, had more aortic valve regurgitation, and less often had connective tissue disease. Patients who underwent cusp repair had longer aortic clamp time (124 ± 43 minutes vs 107 ± 36 minutes, P = .001). In-hospital outcomes were similar between groups and with no operative deaths. A total of 98.3% of patients with cusp repair and 99.3% of patients without cusp repair had mild or less aortic regurgitation at discharge. The median follow-up was 3.9 and 3.2 years for the cusp repair and no cusp repair groups, respectively. At 10 years, estimated prevalence of moderate or more aortic regurgitation was 12% for patients with cusp repair and 7.0% for patients without cusp repair (P = .30). Mean aortic valve gradients were 6.2 mm Hg and 8.0 mm Hg, respectively (P = .01). Ten-year freedom from reoperation was 99% versus 99% (P = .64) in the matched cohort and 97% versus 97%, respectively (P = .30), in the unmatched cohort. Survival at 10 years was 98% after cusp repair and 93% without cusp repair (P = .05).ConclusionsAortic valve reimplantation for patients with tricuspid aortic valves has excellent long-term results. Need for aortic valve cusp repair does not affect long-term outcomes and should not deter surgeons from performing valve-sparing surgery.

Totally endoscopic aortic valve replacement with concomitant trans-aortic mitral valve repair for mitral regurgitation.

Project description:BackgroundMinimally invasive aortic valve procedures through a hemi-sternotomy or a right anterior mini-thoracotomy have gained popularity over the last several years. Totally endoscopic aortic valve replacement (TEAVR) is an innovative and a less invasive (incision-wise) surgical aortic valve replacement technique. The operative steps of TEAVR have been reported previously from our group. Mitral regurgitation (MR) frequently accompanies aortic valve disease that at times may also require repair. Totally endoscopic surgery in such cases has not been tested.Presentation of the techniqueWe present a surgical technique for a totally endoscopic approach to aortic valve replacement and concomitant mitral valve repair for primary and secondary MR. An aortotomy incision was used avoiding an atriotomy, which results in an increase in cross-clamp (XC) and cardiopulmonary bypass (CPB) times that could be associated with higher mortality and morbidity. Neochords (artificial chordae tendineae) were used for primary MR and an edge-to-edge approach for secondary MR.ConclusionTEAVR and concomitant mitral valve repair can be performed successfully with reasonable XC and CPB times with excellent short-term results.
