BACKGROUND: Failure of a small surgical aortic bioprosthesis represents a challenging clinical scenario with valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) often resulting in patient-prosthesis mismatch. Bioprosthetic valve fracture (BVF) performed as a part of the ViV TAVI has recently emerged as an alternative approach with certain types of surgical bioprostheses. CASE SUMMARY: An 81-year-old woman with a history of three surgical aortic valve procedures presented with heart failure...

BACKGROUND: A cluster of aortic bioprosthetic valve failures, most of which were Trifecta bioprostheses, was observed in Southampton General Hospital, Southampton, United Kingdom. This study was performed to assess whether the cluster represents a significant failure of this valve model or whether there is a selection bias that can explain the failure of these valves. METHODS: This retrospective study evaluated all bioprosthetic aortic valve replacement operations performed between 2011 and 2016 inclusive in our center...

BACKGROUND: The durability of aortic valve bioprosthesis and the structural valve deterioration (SVD) are could be treated with valve-in-valve (VIV) transcatheter aortic valve implantation (TAVI). This technique has been proven to be a feasible procedure with good results in selected patients. The aim of this work was to assess the long-term results of this TAVI with an autoexpandable valve in patients with failed Mitroflow (MF) bioprosthetic aortic valves. METHODS: Single center, observational and prospective study that included 65 consecutive patients with symptomatic failed MF bioprosthetic aortic valve, treated with VIV-TAVI...

A 73-year-old woman with a narrow aortic root had undergone aortic valve replacement with a 19-mm Mitroflow valve. Aortic annular enlargement with Manouguian's technique was performed, and the bioprosthesis had been implanted on the tilt in a supra-annular position. Four years after the implantation, echocardiography showed a significant de novo aortic regurgitation, which had not been detected 1 year earlier. In the reoperation, the left coronary leaflet of the bioprosthesis had attached and fused to the wall of the sinus of Valsalva, causing deformation of the valve leaflet and a commissural gap between the left and right coronary leaflets, which appeared to have caused the de novo aortic regurgitation...

We describe a successful bioprosthetic annular stretching in a patient with severe prosthetic aortic valve stenosis from a degenerated 19-mm Mitroflow valve (Sorin Group USA Inc, Arvada, CO, USA). This technique allowed for implantation of a 23-mm Evolut-R Pro valve (Medtronic, Minneapolis, MN, USA) with significant improvement in hemodynamics after prosthetic annular stretching. We have also summarized other case series and case reports which have previously described similar techniques. < Learning objective: Transcatheter valve-in-valve procedure may not be feasible in certain patients who have a relatively smaller size bioprosthetic valve...

An 80-year-old woman with rheumatic valve disease and two previous cardiac surgeries was admitted for heart failure exacerbation. The patient presented stenotic aortic 19-mm Mitroflow and mitral 31-mm Carpentier-Edwards bioprostheses, and was deemed inoperable due to frailty and prohibitive surgical risk. The heart team decided on a compassionate double valve-in-valve procedure, with transfemoral implantation of a 23-mm aortic CoreValve Evolut R and transapical implantation of a 29-mm mitral Edwards SAPIEN 3...

OBJECTIVES: The aim of this study was to examine the effect of different transcatheter heart valves (THVs) on valve leaflet displacement when deployed within bioprosthetic surgical valves and, thereby, risk for coronary obstruction. BACKGROUND: Coronary obstruction is a potentially devastating complication during valve-in-valve (ViV) transcatheter aortic valve replacement. Strategies such as provisional stenting and intentional bioprosthetic valve leaflet laceration have been developed to mitigate this risk...

AIMS: Native valve aortic stenosis is associated with adverse remodelling of the left ventricle and remodelling is stopped or even reversed with aortic valve replacement (AVR). However, the degeneration of bioprostheses and development of structural valve deterioration (SVD) may affect this. METHODS AND RESULTS: To assess the association with SVD, remodelling and outcome 451 patients from a single surgical centre who had undergone AVR with a Mitroflow pericardial bioprosthesis were studied...

AIMS: Bioprosthetic valve fracture (BVF) may improve transvalvular gradients and transcatheter heart valve (THV) expansion during VIV interventions. However, the optimal timing of BVF is unknown. We assessed the impact of timing of BVF (before versus after) for valve-in-valve (VIV) intervention, on hydrodynamic function and THV expansion. METHODS AND RESULTS: Three THV designs were assessed, a 23 mm SAPIEN 3 (S3), small ACURATE neo (ACn) and 23 mm Evolut R, deployed into 21 mm Mitroflow bioprosthetic surgical valves...

A 79-year-old man with heart failure was referred to our attention for a degenerated bio-Bentall Mitroflow 27. The Heart Team decided for a valve-in-valve (ViV) transcatheter aortic valve implantation with an Acurate neoM associated to coronary protection due to high risk of coronary obstruction (CO). Besides the supra-anular design, this case shows additional potential advantages of the Acurate neo in ViV procedures: the upper crown, which is meant to favor supra-anular anchoring, also let to cap the bioprosthesis leaflets and minimize the risk of CO; there is not any interference between the valve cage and the stents protruding into the aorta, avoiding potential stent crushing and assuming an easier future coronary engagement...

AIMS: The commonly used valve-in-valve (VIV) app recommends sizing based on dimensions of both the transcatheter heart valve (THV) and bioprosthetic surgical valve. The implications of hydrodynamic testing to guide VIV sizing are poorly understood. This bench study assessed the hydrodynamic performance of different sizes of self-expanding supra-annular THVs in three different surgical aortic bioprostheses at different implantation depths. METHODS: A small versus medium ACURATE neo (ACn), and a 26 mm versus 29 mm Evolut R were assessed after VIV implantation in 25 mm Mitroflow, Mosaic, and Magna Ease aortic surgical bioprostheses, at three implantation depths (+2 mm, -2 mm, and -6 mm)...

Transcatheter aortic valve implantation (TAVI) is currently recommended in practice guidelines for patients who are at intermediate to high surgical risk for surgical aortic valve replacement. Coronary artery obstruction is a fatal complication of TAVI that occurs in up to 3.5% of the implantations inside a failed surgical bioprosthetic valve (valve-in-valve, ViV). A new technique to address this problem is intentional laceration of the bioprosthetic leaflets, known as BASILICA. In this technique, the leaflets are lacerated to prevent coronary obstruction and may also help in preventing leaflet thrombosis...

Valve-in-valve (ViV) transcatheter procedures have emerged as a feasible, less-invasive treatment option for bioprosthetic structural valve deterioration. However, in the presence of a small bioprosthesis, a significant residual gradient after ViV procedures often occurs and has been associated with poorer clinical outcomes. We report the use of the self-expandable supra-annular ACURATE neo™ valve to treat degenerated Mitroflow (Sorin) aortic bioprosthesis with severe residual elevated gradients followed by valve fracture with a postdilation using a noncompliant balloon leading to significant reduction in residual gradients...
