BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

A 36-year-old pregnant woman with a history of rheumatic heart disease and prior aortic valve replacement and mitral valve repair presented to an outside hospital with severe aortic stenosis. The patient had a cardiac arrest upon labor induction and underwent a transcatheter aortic valve replacement (TAVR), which dislodged two days later. Five months later, the patient underwent removal of the dislodged TAVR and a Ross procedure at the authors' institution. The patient was stable upon discharge, with minimal aortic and pulmonary regurgitation...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has been approved for use in patients with severe aortic stenosis at intermediate, high and extreme surgical risk. This meta-analysis was performed to assess the safety and efficacy of TAVR compared to surgical aortic valve replacement (SAVR) in intermediate risk patients. METHODS: We searched PubMed, EMBASE, Web of science, and the Cochrane Central Register of Controlled Trials databases for studies comparing TAVR versus SAVR in patients at intermediate surgical risk, with a mean Society of Thoracic Surgeon score of 3-8% or a mean logistic European risk score of 10-20%...

Transcatheter aortic valve replacement (TAVR) has exploded into medical care for aortic stenosis, thus changing the treatment options for patients. TAVR is currently approved for extreme-risk, high-risk, and intermediate-risk patients with symptomatic severe aortic stenosis, and randomized trials for low-risk patients are underway. This article traces the trajectory of TAVR as a viable option for higher-risk patients and examines current outcomes.

About 60% of patients with paradoxical low-flow, low-gradient (PLF-LG) aortic stenosis (AS) have a severe disease that justifies aortic valve replacement (AVR). The first step in patients with symptomatic PLF AS should be to rule out measurement errors and treat hypertension. The second step is to distinguish pseudo-severe from true severe AS (TSAS). The third step is to select the optimal treatment modality at the right time. Regarding the second step, projected aortic valve area calculated using stress echocardiography is superior to traditional severity criteria (AVA < 1...

BACKGROUND: Functional impairment of the aorta is a recognized complication of aortic and aortic valve disease. Aortic strain measurement provides effective quantification of mechanical aortic function, and 3-dimenional (3D) approaches may be desirable for serial evaluation. Computerized tomographic angiography (CTA) is routinely performed for various clinical indications, and offers the unique potential to study 3D aortic deformation. We sought to investigate the feasibility of performing 3D aortic strain analysis in a candidate population of patients undergoing transcatheter aortic valve replacement (TAVR)...

INTRODUCTION: Aortic valve stenosis (AS) is the most common valvular pathology in the elderly. Surgical aortic valve replacement (AVR) remains the gold-standard of treatment for AS. However, emerging transcatheter aortic valve replacement (TAVR) has become an increasing alternative to surgery. In a recent survey from the European Society of Cardiology, 9,4% of the physicians stated that age was the main reason to propose for a TAVR instead of surgery. METHODS: We performed a single-center retrospective study including 353 patients (149 patients over 80 years-old, compared to 204 patients between 60-69 years-old) consecutively submitted to AVR between January 1, 2013, and December 31, 2016, to compare the results of both groups in AVR surgery and how we can improve surgery outcome in older patients...

OBJECTIVE: Transcatheter aortic valve replacement (TAVR) reduces left ventricular (LV) afterload and improves prognosis in aortic stenosis (AS) patients. However, LV afterload consists of both valvular and arterial loads, and the benefits of TAVR may be attenuated if the arterial load dominates. We proposed a new hemodynamic index, the Relative Valve Load (RVL), a ratio of mean gradient (MG) and valvuloarterial impedance (Zva), to describe the relative contribution of the valvular load to the global LV load, and examined whether RVL predicted patient outcome following TAVR...

PURPOSE OF REVIEW: Transcatheter valvular interventions have changed the landscape of valvular therapies. We examine some studies on transcatheter valvular interventions published in the year 2017 to better understand their implications on clinical practice and future research. RECENT FINDINGS: Findings from the SURTAVI study suggest TAVR to be a reasonable option in intermediate risk patients with aortic stenosis. Recent studies indicate that valve leaflet thrombosis is associated with poor outcomes...

BACKGROUND: Antithrombotic recommendations following transcatheter aortic valve replacement (TAVR) are largely based on previous trial protocols. The efficacy and risk of anticoagulation has not been systematically assessed. The aim of this study was to determine the efficacy and safety of oral anticoagulation in patients with atrial fibrillation (AF) following TAVR with the Lotus Valve System (Boston Scientific, Malborough, MA, USA). METHODS: Consecutive patients with severe aortic stenosis who underwent Lotus valve implantation were prospectively recruited (n=164)...

This report provides a brief overview of the basic principles, recent advances, and recommendations for the treatment of severe aortic stenosis with transcatheter aortic valve replacement (TAVR) in adults. Approaches that avoid neurological, cardiac and peripheral vascular complications have been developed. In addition, TAVR can be performed in intermediate- and low-risk patients. However, these procedures require specialized training and may not allow for complete resolution of the underlying issue. Even if cardiologists learn to perform the procedure and despite advancements in device technology, TAVR is still susceptible to structural valve degeneration, thrombosis and late cerebral embolization...

Transcatheter aortic replacement has become the standard of care for patients with severe aortic valve stenosis. With advancement of technologies, this technique has become much safer and simpler. Both general anesthesia (GA) and monitored anesthesia care (MAC) have been provided for transcatheter aortic valve replacement (TAVR). MAC or awake transcatheter valve replacement was shown to carry similar clinical outcomes with significantly reduced length of stay. We reviewed the literature and presented our practical minimalist anesthesia approach to awake TAVR...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a minimally invasive approach to aortic valve replacement. However, critical cardiovascular collapse can occur during the procedure for various reasons. CASE PRESENTATION: A 90-year-old man with severe aortic stenosis and left circumflex artery stenosis developed acute torrential mitral regurgitation (MR) during TAVR. The valve deployment process induced left ventricular dyssynchrony due to left bundle-branch block and myocardial ischemia in the left circumflex artery region with torrential MR...
