A 59-year-old female with Tetralogy of Fallot had a previous complete repair with RVOT patch enlargement. She developed subsequent severe symptomatic (NYHA III) pulmonary regurgitation with severe RV dilatation. She had a concomitant interstitial lung disease secondary to hypersensitivity pneumonitis that precluded her from cardiac surgery. After preprocedural assessment using computed tomography, echocardiography and invasive angiography we decided to implant a 29 mm Edwards Sapien 3 valve without pre-stenting...

We describe the case of a 57-year-old man who had severe mitral valve stenosis and regurgitation without significant annular calcification. He was not a candidate for surgical valve replacement or repair because of his substantial comorbid conditions, overall frailty, and elevated surgical risk. He underwent successful transcatheter mitral valve replacement of his native mitral valve with compassionate, off-label use of an Edwards Sapien 3 valve. A search of the literature produced no other cases like ours, which represents a further evolution of the transcatheter valve implantation concept...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the method of choice for patients with severe aortic valve stenosis, who are ineligible or at high risk for surgery. Though TAVR leads to a significant reduction in mortality, a notable amount of patients are re-hospitalized early after TAVR. Parameters or biomarkers predicting outcome are therefore needed to identify patients who benefit most. Specific monocyte subsets have been associated with cardiovascular diseases and were shown to possess prognostic value...

The case is reported of a successful transcatheter implantation of an Edwards SAPIEN 3 valve (29 mm) into a failing tricuspid bioprosthesis (Sorin Pericarbon, 31 mm). The procedure was performed in a 69-year-old woman with post-rheumatic mitral and tricuspid valve disease. Multiple previous cardiac surgeries precluded the use of another surgical approach. A large, organized, two-piece thrombus in the enlarged right atrium was not considered an absolute contraindication to the procedure. The SAPIEN 3 valve was implanted under general anesthesia, via a femoral venous access, under three-dimensional transesophageal echocardiography guidance...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. METHODS: From July 2008 to May 2015, 856 transcatheter heart valves were implanted at our center (age: 80...

Investigations aimed at defining the 3-D configuration of eukaryotic chromosomes have consistently encountered an endogenous population of chromosome-derived circular genomic DNA, referred to as extrachromosomal circular DNA (eccDNA). While the production, distribution, and activities of eccDNAs remain understudied, eccDNA formation from specific regions of the linear genome has profound consequences on the regulatory and coding capabilities for these regions. Here, we define eccDNA distributions in C. elegans and in three human cell types, utilizing a set of DNA-topology dependent approaches for enrichment and characterization...

OBJECTIVES: The aims of this study were to determine plasma elevations of biomarkers of myocardial injury associated with transfemoral (TF) transcatheter aortic valve replacement (TAVR) and to evaluate their prognostic value. BACKGROUND: Increases in biomarkers of myocardial injury are a common finding after TAVR, but their clinical significance is unclear. METHODS: In 756 consecutive TF TAVR patients, cardiac high-sensitivity troponin I (hsTnI) and creatine kinase MB (CK-MB) levels were measured at pre-defined time points to assess the occurrence of myocardial injury (defined as 15 times the upper reference limit for hsTnI [≥1...

Human papillomavirus type 58 is found in 10-18% of cervical cancers in East Asia but rather uncommon elsewhere. The distribution and oncogenic potential of HPV58 variants appear to be heterogeneous since the E7 T20I/G63S variant is more prevalent in East Asia and confers 7-9 fold higher risk for cervical precancer and cancer. However, the underlying genomic mechanisms that explain the geographic and carcinogenic diversity of HPV58 variants are still poorly understood. In this study, we used a combination of phylogenetic analyses and bioinformatics to investigate the deep evolutionary history of HPV58 complete genome variants...

BACKGROUND: Transcatheter mitral valve implantation (TMVI) is still in its infancy and is mainly limited to valve-in-valve or valve-in-ring implantations. We present the early experience with TMVI for severe calcified native MV stenosis. METHODS: Between January 2014 and June 2015, 6 of 11 patients screened (mean age, 77.4 ± 6.3 years; 66% men) with severe native mitral valve (MV) stenosis (mean gradient [Pmean], 11.1 ± 2.1 mm Hg; mean effective orifice area [EOA], 0...

BACKGROUND: The use of transcatheter aortic valve replacement (TAVR) is increasing worldwide. We present our 6-year experience using three-dimensional (3D) transesophageal echocardiography (TEE) and investigate whether different sizing methods of the aortic annulus lead to different prosthesis size that may impact outcome. METHODS: We investigated 262 patients who underwent TAVR and had 3D TEE data sets of the aortic annulus. We have used the area-derived diameter (Darea = 2(area/π)) and the circumference-derived diameter (Dcirc = Circumference/π) to size the prosthesis in separate populations in different time periods...

Background -Transcatheter heart valve (THV) thrombosis has been increasingly reported. In these studies, thrombus quantification has been based on 2D assessment of a 3D phenomenon. Methods -Post-procedural four-dimensional, volume-rendered CT (4DCT) data of CoreValve, Evolut R, and SAPIEN 3 transcatheter aortic valve replacement (TAVR) patients enrolled in the RESOLVE trial were included in this analysis. Patients on anticoagulation were excluded. SAPIEN 3 and CoreValve/Evolut R patients with and without hypo-attenuated leaflet thickening (HALT) were included in order to study differences between groups...

A 79-year-old woman with severe mitral annular calcification was scheduled for mitral valve replacement. A SAPIEN 3 valve was implanted in mitral position using an open surgical approach. Immediately after cardiopulmonary bypass, bleeding from an unidentified source was encountered. Cardiopulmonary bypass was emergently resumed and a laceration of the left ventricular apex due to the valve delivery system was detected. Risk factors specific to the open surgical approach include a decompressed ventricle, decreased annulus to apical distance, and the absence of continuous fluoroscopic and echocardiographic imaging...

AIMS: Transcatheter valve-in-valve (VIV) implantation in small surgical tissue valves is challenged by the problem of residual stenosis. We report our first ten cases of fracturing small dysfunctional Mitroflow bioprostheses by high-pressure balloon dilatation to increase the internal diameter of the surgical valve before VIV (BF-VIV). METHODS AND RESULTS: BF-VIV was performed in 10 patients (mean age 84±4 years) with failing Mitroflow valves size 19 mm (n=3, threshold of fracture 15 atm) and 21 mm (n=7, threshold of fracture 13 atm)...

BACKGROUND: Balloon predilatation of the aortic valve has been regarded as an essential step during the transcatheter aortic valve implantation (TAVI) procedure. However, recent evidence has suggested that aortic valvuloplasty may cause complications and that high success rates may be obtained without prior dilatation of the valve. We hypothesize that TAVI performed without predilatation of the aortic valve and using new-generation balloon-expandable transcatheter heart valves is associated with a better net clinical benefit than TAVI performed with predilatation...

Importance: In patients with severe aortic stenosis (AS) at intermediate surgical risk, treatment with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) results in similar 2-year survival. The effect of TAVR vs SAVR on health status in patients at intermediate surgical risk is unknown. Objective: To compare health-related quality of life among intermediate-risk patients with severe AS treated with either TAVR or SAVR. Design, Setting, and Participants: Between December 2011 and November 2013, 2032 intermediate-risk patients with severe AS were randomized to TAVR with the Sapien XT valve or SAVR in the Placement of Aortic Transcatheter Valve 2 Trial and were followed up for 2 years...
