CIEF represents an elegant technique especially for the separation of structural similar analytes, whereas MS is a state of the art instrumentation for the identification and characterization of biomolecules. The combination of both techniques can be realized by hyphenating CIEF with CZE-ESI-MS applying a mechanical valve. During the CZE step, the remaining ESI-interfering components of the CIEF electrolyte are separated from the analytes prior to MS detection. In this work, a multiple heart-cut approach is presented expanding our previous single heart-cut concept resulting in a dramatical reduction of analysis time...

OBJECTIVE: In this paper, we present an endoscopic expandable sizer conceived to allow thoracoscopic aortic valve replacement with a sutureless prosthesis using a dynamic sizing of the aortic annulus. METHODS: Ten aortic torsos were prepared using a five-trocar thoracoscopic setting. Once the aortotomy was performed and the aortic valve leaflets removed, the technical feasibility of the endoscopic sizing (introduction into the trocar, expansion into the aortic annulus, determination of the valve size, and retraction) with the device was assessed...

Coronary obstruction during or after transcatheter aortic valve replacement is a rare and catastrophic sequela that occurs most frequently just after valve implantation. Even rarer is the delayed clinical presentation, in some few patients, of coronary obstruction on the day after self-expandable valve implantation. Here we describe a case of balloon-expandable (not self-expandable) transcatheter aortic valve replacement, followed by partial obstruction of the left main coronary artery on the day after that procedure in a 93-year-old man, despite normal left ventricular contraction just after valve implantation...

AIMS: The aim was to determine the best functional position of a transcatheter heart valve (THV) implanted as a valve-in-valve (ViV) procedure in small rapid deployment valves (RDV) in an in vitro model. METHODS AND RESULTS: A 21mm Perceval™, Enable™ or INTUITY™ RDV was mounted into a pulse duplicator and a 23mm balloon-expandable or a self-expanding THV was deployed (valve-in-valve) in two different positions. Under physiological hydrodynamic conditions, performance of the THV was characterized by mean transvalvular pressure gradient (MPG), effective orifice area (EOA) and regurgitation volume (RV)...

Recent data from landmark trials suggest that the indications for cardiac pacing and implantable cardioverter defibrillators (ICDs) are set to expand to include heart failure, sleep-disordered breathing, and possibly routine implantation in patients with myocardial infarction and poor ventricular function.[1] This will inevitably result in more patients with cardiac devices undergoing surgeries. Perioperative electromagnetic interference and their potential effects on ICDs pose considerable challenges to the anesthesiologists...

Sutureless aortic bioprostheses (SAB) are increasingly being used to provide shorter cross-clamp time. Valve-in-valve transcatheter aortic valve replacement (VIV-A) is shown to be effective and safe in the vast majority of patients with degenerated bioprosthetics, yet its' use in SAB failure is infrequent. We present a case of balloon-expandable VIV-A in an 80-year-old woman who suffered severe symptomatic aortic regurgitation in a failed Perceval S 21-mm valve. Computed tomography scan demonstrated a deformed valve...

Surgical techniques for the treatment of mitral valve disease (MVD) have continuously evolved; however, anatomical details like severe annular calcification remain challenging and require sophisticated surgical strategies. Among patients with symptomatic MVD referred for surgical valve repair or replacement, four presented with circumferential calcification of the mitral annulus precluding conventional surgical techniques. Successful treatment by implanting a balloon-expandable transcatheter aortic heart valve using an antegrade surgical access was performed...

Advances in ultrasound, computer, and electronics technology have permitted three-dimensional echocardiography (3DE) to become a clinically viable imaging modality, with significant impact on patient diagnosis, management, and outcome. Thanks to the inception of a fully sampled matrix transducer for transthoracic and transesophageal probes, 3DE now offers much faster and easier data acquisition, immediate display of anatomy, and the possibility of online quantitative analysis of cardiac chambers and heart valves...

PURPOSE: Transcatheter aortic valve implantation (TA-TAVI) is a well-established treatment for aortic valve stenosis in high-risk patients and indications have been continuously expanding to also include intermediate-risk patients. However, in low-risk patients, experiences are still sparse and although clinical outcomes have been shown favorable results, HRQoL has remained unexplored. The aim of this report was to describe the long-term health-related quality-of-life (HRQoL) in low-risk patients randomized to TA-TAVI or surgical aortic valve replacement (SAVR)...

Various materials that are used for vascular and heart valve prostheses carry drawbacks: some require anticoagulant drugs or have moderate durability; others are not suitable for endovascular treatment. These prostheses are associated with bacterial infections. A material potentially suitable for prostheses is Dyneema Purity®, made of ultra-high-molecular-weight polyethylene. Dyneema Purity® fibers are very thin, flexible, resistant to fatigue and abrasion, and have high strength. S. aureus adherence to Dyneema Purity® was tested and compared with currently used cardiovascular prostheses...

AIMS: Transcatheter aortic valve implantation (TAVI) has gained rapid acceptance for patients with severe aortic stenosis (AS) at high surgical risk for conventional valve replacement. Although TAVI is now a relatively mature technique, limited data about long-term valvular function are available. Our aim was to report the five-year echocardiographic data evaluating valve performance from three early European feasibility studies designed to assess the safety and effectiveness of the first-generation balloon-expandable transcatheter heart valve (SAPIEN THV)...

BACKGROUND: While transcatheter aortic valve implantation (TAVI) is established for treating high-operative risk surgical aortic valve replacement candidates, until recently the smallest transcatheter heart valve (THV) measured 23 mm, posing greater risk for annular rupture and THV failure in patients with aortic stenosis (AS) with small aortic annuli (≤20 mm). OBJECTIVES: In the setting of a multicentre registry, we report on the safety, efficacy and early clinical outcomes of the SAPIEN XT 20 mm balloon-expanding THV...

BACKGROUND: Underfilling or overfilling of balloon-expandable transcatheter heart valves (THVs) during transcatheter aortic valve implantation (TAVI) is commonly used to improve conformity to small or calcified annuli in order to avoid serious complications. However, little is known about this technique. This study assessed the effects of underfilling and overfilling of THVs. METHODS AND RESULTS: Data from 213 consecutive TAVI patients treated with balloon-expandable THVs in 4 Japanese centers between October 2013 and December 2014 were prospectively analyzed; 23-mm and 26-mm THVs were implanted in 96 cases (56 underfilling, 22 nominal filling, and 18 overfilling) and 38 cases (23 underfilling and 15 nominal filling), respectively...
