We present a case of left ventricular outflow tract (LVOT) obstruction after double valve re-replacement with bioprostheses. A 72-year-old man, who had undergone double valve replacement (DVR) with bioprosthetic valves 9 years previously, underwent re-replacement of valves because of structural valve deterioration. However, owing to LVOT obstruction related to the bioprosthesis in the mitral position, acute pulmonary edema occurred immediately after surgery. LVOT obstruction was diagnosed by emergent cardiac catheterization...

OBJECTIVES: Contemporary experience in mitral valve (MV) repair for children with rheumatic heart disease (RHD) is limited, despite the potential advantages of repair over replacement. We reviewed our long-term outcomes of rheumatic MV repair and compared them with the outcomes of MV replacement in children with RHD. METHODS: This study is a review of 419 children (≤18 years) with RHD who underwent primary isolated MV surgery between 1992 and 2015, which comprised MV repair (336 patients; 80...

Patients with isolated functional or recurrent tricuspid regurgitation are often denied surgery because they are considered to be at high risk. Transcatheter valve therapy provides a less invasive alternative for tricuspid regurgitation associated with right heart failure. We have evaluated the feasibility of transcatheter tricuspid valve implantation of the NaviGate valved stent in a long-term swine model. The valved stent was successfully implanted through transjugular and transatrial approaches on the beating heart with excellent hemodynamic and valve performance...

BACKGROUND:  The Mitroflow pericardial bioprosthesis (MPB) has been recently associated with a high incidence of early structural failures, questioning its validity as cardiac valve substitute. We have therefore reviewed our experience with this device. MATERIALS AND METHODS:  A total of 398 patients with a mean age of 75 ± 7 years (58% above the age of 75 years) had aortic valve replacement with a Mitroflow prosthesis (2005-2015). Most patients had calcific aortic stenosis (86%) and were in sinus rhythm (89%)...

Percutaneous pulmonary valve implantation is increasingly adopted as an alternative procedure to surgery in dysfunctional homograft, and in patients with "native" or wide right ventricle outflow tract dysfunction. Pre-stenting is mandatory in this category of patients for many reasons, one of which is to create an adequate landing zone for the bioprosthesis. Here we report on a tricky situation that occurred during pre-stenting, and we describe how we successfully overcame it.

BACKGROUND: With the emergence of transcatheter mitral valve replacement, it appears crucial to provide contemporary references with which this new technology can be compared. At our institution, transoesophageal echocardiography is systematically performed before discharge after surgical mitral valve replacement. AIM: To evaluate the rate and determinants of paravalvular regurgitation after surgical mitral valve replacement. METHODS: We collected medical history, indication, type of surgery and in-hospital outcome in all consecutive patients who underwent a mitral valve replacement in the past 2 years at our institution...

OBJECTIVE: To determine the safety and efficacy of valve-in-valve transcatheter aortic valve replacement (ViV) versus redo surgical aortic valve replacement (SAVR) for the treatment of previously failed aortic bioprostheses. BACKGROUND: Valve-in-valve has emerged as a treatment option for patients with a failed aortic bioprosthesis. Evidence for safety and efficacy remains limited to small studies. METHODS: Medline and Embase were searched to 2017 for studies that directly compared ViV to redo SAVR...

BACKGROUND: Dysmetabolic profile has been associated with native aortic valve stenosis. However, there are limited data on the effects of an atherogenic milieu and its potential implications on the structural and hemodynamic deterioration of aortic bioprosthetic valves. OBJECTIVES: This prospective longitudinal study sought to determine the predictors and impact on outcomes of hemodynamic valve deterioration (HVD) of surgically implanted aortic bioprostheses. METHODS: A total of 137 patients with an aortic bioprosthesis implanted for a median time of 6...

Currently available bioprosthetic heart valves have been successfully used clinically; however, they have several limitations. Alternatively, tissue-engineering techniques can be used. However, there are limited data concerning the impact of storage conditions of scaffolds on their biomechanics and morphology. The aim of this study was to determine the effect of different storage conditions on the biomechanics and morphology of pulmonary valve dedicated for the acellular scaffold preparation to achieve optimal conditions to obtain stable heart valve prostheses...

INTRODUCTION: Aortic valve bioprostheses, which do not mandate chronic anticoagulation, are prone to structural valve degeneration (SVD). The processes involved in SVD are likely multifactorial. We hypothesized that inflammation and macrophage activation could be involved in SVD. METHODS: In 203 patients with an aortic valve bioprosthesis, we evaluated the association between the macrophage activation marker soluble CD14 (sCD14) and SVD. RESULTS: After a mean follow-up of 8 ± 3 years, 42 (21%) patients developed SVD...

OBJECTIVES: Stentless bioprosthetic valves provide hemodynamic advantages over stented valves as well as excellent durability. However, some primary tissue failures in bioprostheses have been reported. This study was conducted to evaluate the morphometrical and biomechanical properties of the stentless Medtronic Freestyle™ aortic root bioprosthesis, to identify any arising problem areas, and to speculate on a potential solution. METHODS: The three-dimensional heterogeneity of the stentless bioprosthesis wall was investigated using computed tomography...

OBJECTIVES: The aim of this study was to assess the implications of concomitant tricuspid regurgitation (TR) in patients undergoing valve-in-valve (VIV) transcatheter aortic valve replacement. BACKGROUND: Patients undergoing VIV transcatheter aortic valve replacement with concomitant TR may have worse outcomes, and optimal management remains undetermined. METHODS: The multicenter PARTNER 2 (Placement of Aortic Transcatheter Valves) VIV trial enrolled patients with symptomatic degenerated surgical aortic bioprostheses who were at high risk for reoperation...

Background: Tenets of chest wall reconstruction for malignancy are well known; however, the insertion of synthetic prosthetic material to achieve rigid and nonrigid skeletal reconstruction could be associated with more complications including infection and extrusion especially in high risk patients. This includes fungating, infected tumors, previous radiotherapy, scars, smoking, diabetes, and morbid obesity. Bioprosthesis Acelluar Dermal Matrix Strattice would be a substitute to resist infection and provide stable coverage...

OBJECTIVES: To assess the feasibility and results of 'valve-in-valve' implantation using the 23-mm CoreValve for the treatment of degenerated 19-mm and 21-mm Mitroflow bioprostheses. METHODS: We retrospectively analysed all consecutive patients who underwent transcatheter aortic valve implantation for 19-mm and 21-mm Mitroflow bioprostheses. The height of implantation with respect to the ring of the Mitroflow prosthesis was targeted at -6 mm for the first 3 cases...

BACKGROUND: To investigate epidemiological trends of infective endocarditis (IE) in western Norway a retrospective study was performed. METHODS: Characteristics of 706 IE admissions from 1996 to 2005 and 2006 to 2015 were analysed and compared using the Chi-square test for categorical variables and the t-test for age. Survival was analysed by multiple Cox regression and reported by the hazard ratio (HR). RESULTS: Mean annual incidence rates increased from 4...
