BACKGROUND: Structural valve deterioration (SVD) is a known limitation of bioprosthetic valves. Recent reports have suggested a concerning rate of early SVD in patients receiving a Mitroflow aortic bioprosthesis. We therefore compared the incidence of SVD and SVD requiring reoperation among patients receiving a Mitroflow versus a common contemporary bioprosthesis. METHODS: A retrospective cohort analysis was performed on 592 patients receiving a Mitroflow aortic bioprosthesis at our institution between 2010 and 2014...

REVIEW
Akash Kataruka, Catherine M Otto
Transcatheter aortic valve implantation (TAVI) is a minimally invasive procedure to treat severe symptomatic aortic stenosis. While the TAVI procedure can be performed safely and provide excellent 5-year results, little is known about long-term durability. TAVI valves are composed of bioprosthetic leaflets are prone to deterioration, which are categorized as structural valve deterioration (SVD) and non-SVD. SVD refers to an intrinsic pathology of the leaflets or stent structure with mechanisms that include leaflet calcification, leaflet tear, stent fracture, or stent creep...

OBJECTIVES: Structural valve deterioration (SVD) remains a major bioprosthesis-related complication, as recently described for the Mitroflow valve (models LX and 12A) (LivaNova, London, United Kingdom). The real incidence of the SVD risk remains unclear, often due to methodologic pitfalls by systematically using the Kaplan-Meier estimator and/or the Cox model. In this report, we propose for the first time a precise statistical modeling of this issue. METHODS: Five hundred sixty-one patients who underwent aortic valve replacement with the aortic Mitroflow valve between 2002 and 2007 were included...

BACKGROUND: The incidence of structural valve deterioration after bioprosthesis (BP) aortic valve replacement (AVR) established on the basis of reoperation may substantially underestimate the true incidence. The objective is to determine the rate, timing, correlates, and association between hemodynamic valve deterioration (HVD) and outcomes assessed by Doppler echocardiography after surgical BP AVR. METHODS: A total of 1387 patients (62.2% male, 70.5±7.8 years of age) who underwent BP AVR were included in this retrospective study...

Cryopreserved pulmonary homograft (CPH) implantation remains the gold standard for reconstruction of the right ventricular outflow tract (RVOT). Harvesting homografts < 24-h post mortem is the international norm, thereby largely excluding cadaveric donors. This study examines the structural integrity and stability of ovine pulmonary homografts harvested after a 48-h post mortem period, cryopreserved and then implanted for up to 180 days. Fifteen ovine pulmonary homografts were harvested 48-h post mortem and cryopreserved...

Structural valve deterioration is a well-studied phenomenon in bioprosthetic heart valves. Conversely, structural valve deterioration after transcatheter aortic valve implantation is not as well-elucidated. Therefore, late surgical explantation after transcatheter aortic valve implantation is an infrequent procedure, and thus, surgical findings and management of such cases remain unclear, particularly in patients previously labelled as 'inoperable' or at 'high risk'. Herein, we report the case of a late surgical explantation of a transcatheter heart valve (THV) 7 years after its implantation in a patient with a porcelain aorta and periprosthetic regurgitation...

BACKGROUND: The reoperation for isolated tricuspid regurgitation in rheumatic population is rare and still unclear and controversial because of the rarity of publications. The aim of this study was to analyze short and long-term results and outcome of tricuspid valve surgery after left-sided valve surgery in rheumatic patients. METHODS: Twenty six consecutive rheumatic patients who underwent isolated tricuspid valve surgery after left-sided valve surgery between January 2000 and January2017 were retrospectively registered in the study...

OBJECTIVE: To report the hemodynamic profile and short- and medium-term outcomes of Freedom Solo and Solo Smart stentless aortic valves implanted at our center. METHODS: Between 2009 and 2015, all patients undergoing aortic valve replacement using Solo stentless valves at our center were enrolled. Clinical and echocardiographic follow-up was carried out six months postoperatively. Survival and major events, including structural valve deterioration and non-structural valve dysfunction, endocarditis, reoperation and stroke, were assessed through medical records or telephone interview with the referring cardiologist up to November 2015 (mean and maximum follow-up 39±22 and 78 months, respectively)...

BACKGROUND: The Cardioband system enables percutaneous surgical-like direct mitral valve annuloplasty and, thereby, repair of severe functional mitral valve regurgitation (MR) in patients with advanced systolic heart failure (HF) and dilation of the left ventricular (LV) annulus. Since the device is anchored by screws in the LV annulus, limited myocardial injury is likely to occur. METHODS AND RESULTS: Five patients (Society of Thoracic Surgeons score: 2.7 ± 0...

Venous valves are bicuspidal valves that ensure that blood in veins only flows back to the heart. To prevent retrograde blood flow, the two intraluminal leaflets meet in the center of the vein and occlude the vessel. In fluid-structure interaction (FSI) simulations of venous valves, the large structural displacements may lead to mesh deteriorations and entanglements, causing instabilities of the solver and, consequently, the numerical solution to diverge. In this paper, we propose an arbitrary Lagrangian-Eulerian (ALE) scheme for FSI simulations designed to solve these instabilities...

With the expanding indication of transcatheter aortic valve implantation (TAVI) to younger, lower risk population, transcatheter aortic valve (TAV) long-term durability is becoming an emerging issue to face with. Recently, the standardization of structural valve deterioration (SVD) definition by a join committee of the European Association of Percutaneous Cardiovascular Interventions (EAPCI), the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) has permitted to evaluate for the first time the rates of TAV durability with comparable endpoint...
