OBJECTIVE: Transcatheter aortic valve implantation (TAVI) has been adopted rapidly in Europe. TAVI national registries can augment understanding of technologies and represent real-world experience, providing further clinical insights. We undertook a meta-analysis of published European national TAVI registries to assess current results following TAVI in Europe. METHODS: Electronic databases were searched. The review focused on the comparison of the following TAVI strategies: transfemoral (TF) and transapical (TA) SAPIEN and CoreValve implantation...

Prosthetic valve endocarditis (PVE) after transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) is a potential life threatening complication. Better understanding of the incidence, predictors, clinical presentation, diagnostic measures, complications and management of PVE may help improve TAVI long-term outcome. We report a case of TAVI-PVE in an 80-year-old high risk patient in whom SAVR was successfully performed. We have reviewed literature regarding TAVI-PVE.

INTRODUCTION: Percutaneous aortic valve replacement (transcatheter aortic valve implantation (TAVI)) notably increases the likelihood of the appearance of a complete left bundle branch block (LBBB) by direct lesion of the LBB of His. This block can lead to high-grade atrioventricular conduction disturbances responsible for a poorer prognosis. The management of this complication remains controversial. METHOD AND ANALYSIS: The screening of LBBB after TAVI persisting for more than 24 hours will be conducted by surface ECG...

Transcatheter aortic valve implantation (TAVI) has revolutionized the management of elderly patients with symptomatic severe aortic stenosis in the western world. It is a valuable alternative to surgical aortic valve replacement in patients, who are inoperable or at high surgical risk due to co-morbidities. The prevalence of aortic stenosis increases sharply with age after the sixth decade and is expected to have a significant impact on the geriatric health care system of India, given the rapid increase in life expectancy in recent years...

Atrial fibrillation (AF) is a common arrhythmia in patients with aortic stenosis. When these patients are treated medically or by surgical aortic valve replacement, AF is associated with increased risk of adverse events including death. Growing evidence suggests a significant impact of AF on outcomes also in patients with aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). Conversely, limited evidence is available regarding the optimal management of this condition. This review aims to summarize prevalence, pathophysiology, prognosis, and treatment of AF in patients undergoing TAVI...

Transcatheter aortic valve implantation (TAVI) is nowadays a worldwide technique in the field of treating aortic stenosis. One of the main side effects linked to the technique are mostly attached to rhythm disturbances, such as atrioventricular (AV) and intraventricular blocks. Consequently, a pacemaker implantation is often required. That implantation rate is estimated between 8 and 30%, depending on the valve chosen. Thanks to main meta analysis on the subject, it has been managed to isolate the following risks factors for AV block development: preoperative right bundle branch block (RBBB: the most powerful element), complete AV block during the procedure, male gender, a so-called porcelain aorta, the absence of previous valvular surgery, the aortic annulus size (i...

There is a growing body of evidence demonstrating the durability of current transcatheter aortic valve implantation (TAVI) devices up to 5 years. However, it is well known that transcatheter aortic valves can degenerate in a manner similar to surgical bioprostheses. In this review we briefly discuss the modes of failure of trans-catheter aortic valves and their potential management.

Transcatheter aortic valve implantation (TAVI) has evolved from an exclusive, highly complex and hazardous procedure into a mature, safe and streamlined therapy for patients with severe aortic stenosis (AS). Various successive device iterations and product refinements have created a dynamic and competitive field with a spectrum of different CE-marked transcatheter heart valve (THV) designs. This review provides a practical overview of current CE-marked THVs with a focus on respective sizing algorithms and delivery strategies...

Transcatheter aortic valve implantation (TAVI) is now the principal therapeutic option in patients with severe aortic stenosis deemed inoperable or at high surgical risk. Implementing TAVI in a lower risk profile population could be limited by relatively high cerebrovascular event rates related to the procedure. Diffusion-weighted magnetic resonance imaging studies have demonstrated the ubiquitous presence of silent embolic cerebral infarcts after TAVI, with some data relating these lesions to subsequent cognitive decline...

Transcatheter aortic valve implantation (TAVI) underwent progressive improvements until it became the default therapy for inoperable patients, and a recommended therapy in high-risk operable patients with symptomatic severe aortic stenosis. Recent evidence will further support TAVI as treatment for a growing number of patients. Areas covered: This review will discuss on the current knowledge about the role of both pre-procedural chronic kidney disease (CKD) and post-procedural acute kidney injury (AKI) in adult patients with severe aortic stenosis undergoing TAVI...

Widespread acceptance of evidence-based medicine has led to the proliferation of clinical practice guidelines as the primary mode of communicating current best practices across a range of chronic diseases. Despite overwhelming evidence supporting the benefits of their use, there is a long history of poor uptake by providers. Nonadherence to clinical practice guidelines is referred to as clinical inertia and represents provider failure to initiate or intensify treatment despite a clear indication to do so. Here we review evidence for the ubiquity of clinical inertia across a variety of chronic health conditions, as well as the organizational and system, patient, and provider factors that serve to maintain it...

Voltage-gated sodium channels are present in different tissues within the human body, predominantly nerve, muscle, and heart. The sodium channel is composed of four similar domains, each containing six transmembrane segments. Each domain can be functionally organized into a voltage-sensing region and a pore region. The sodium channel may exist in resting, activated, fast inactivated, or slow inactivated states. Upon depolarization, when the channel opens, the fast inactivation gate is in its open state. Within the time frame of milliseconds, this gate closes and blocks the channel pore from conducting any more sodium ions...

OBJECTIVES: Made available since 2002, transcatheter aortic valve implantation (TAVI) is a minimally invasive new intervention which can provide significant survival improvement to patients with aortic stenosis. However, TAVI is expensive and currently not reimbursed by many governments. Some governments and institutions have been conducting health technology assessments (HTAs) to inform their reimbursement decisions. The aim of the present study is to review HTAs that have relied on a cost-effectiveness analysis to inform reimbursement decisions of TAVI...

Aortic stenosis (AS) is the most frequent valve disease in the elderly population Treatment is valve replacement either by open surgery, or in the case of patients at high surgical risk, by TAVI (Transcatheter Aortic Valve Implantation). However, almost 40% of patients who have undergone TAVI show poor health outcomes, either due to death or because their clinical status does not improved. This review examines the non-cardiac aspects of patients with AS, which may help answer three key questions in order to evaluate this condition pre-surgically: 1) Are the symptoms presented by the patient exclusively explained by the AS, or are there other factors or comorbidities that could justify or increase them?, 2) What possibilities for improvement of health status and quality of life has the patient after the valve replacement?, and 3) How can we reduce the risk of a futile valve replacement?...
