BACKGROUND: Previous trials have shown that, among high-risk patients with aortic stenosis, survival rates are similar for transcatheter aortic-valve implantation (TAVI) and surgical aortic valve replacement. The study aimed to compare the outcomes of aortic valve replacement according to the adopted surgical approach in intermediate and low risk patients. METHODS: This is a retrospective, observational, cohort study of prospectively collected data from 421 patients undergoing isolated aortic valve replacement between 2011 and 2015...

Bicuspid aortic valve (BAV) stenosis has been considered a contraindication to transcatheter aortic valve implantation (TAVI). The aim of this study is to compare the efficacy and safety of TAVI in patients with BAV with those with tricuspid aortic valve (TAV) using balloon-expandable and self-expanding transcatheter heart valves. This retrospective study included 823 consecutive patients with severe, symptomatic aortic valve stenosis undergoing TAVI in 2 institutions, Baylor Heart and Vascular Hospital (Dallas, TX) and The Heart Hospital Baylor Plano (Plano, TX), from January 2012 to February 2016...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for patients with severe aortic valve stenosis. This procedure requires pre-operative planning by assessment of aortic dimensions on CT Angiography (CTA). It is well-known that the aortic root dimensions vary over the heart cycle. However, sizing is commonly performed at either mid-systole or end-diastole only, which has resulted in an inadequate understanding of its full dynamic behavior. STUDY GOAL: We studied the variation in annulus measurements during the cardiac cycle and determined if this variation is dependent on the amount of calcification at the annulus...

OBJECTIVE: High-pitch protocols are increasingly used in cardiovascular CT assessment for transcatheter aortic valve implantation (TAVI), but the impact on diagnostic image quality is not known. METHODS: We reviewed 95 consecutive TAVI studies: 44 (46%) high-pitch and 51 (54%) standard-pitch. Single high-pitch scans were performed regardless of heart rate. For standard-pitch acquisitions, a separate CT-aortogram and CT-coronary angiogram were performed with prospective gating, unless heart rate was ≥70 beats/min, when retrospective gating was used...

Cardiac computed tomography (CT) provides additional information with ultrasound in the transcatheter heart valve (THV) size selection. However, the influence of these incremental data on outcomes has not been evaluated in a randomized study. A single-center prospective, randomized, and open study was performed. Patients referred for transfemoral transcatheter aortic valve implantation with a balloon-expandable endoprothesis were included. THV size selection was performed using either transthoracic and transesophageal echocardiography data (control group) or ultrasound and CT results (CT group)...

BACKGROUND: Risk prediction in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) is challenging. Development of novel markers for patient risk assessment is of great clinical value. Deceleration capacity (DC) of heart rate is a strong risk predictor in post-infarction patients. HYPOTHESIS: DC provides prognostic information in patients undergoing TAVI. METHODS: We enrolled 374 consecutive patients with severe AS undergoing TAVI...

The first case of a novel JenaValve design using the transfemoral approach in a 78 year old female patient with pure aortic regurgitation is described. The implantation was successfully performed with excellent haemodynamics and good clinical outcome at 6 months follow up. The technology is especially appealing in non-calcified anatomies due to the clipping mechanism that has been previously utilized in the transapical design.

Since the advent of bioprosthetic valves, the implications of long-term anticoagulation after valve replacement are unclear. There are very little data on outcomes of long-term anticoagulation after transcatheter aortic valve implantation (TAVI). Our aim was to conduct a systematic review of literature regarding anticoagulation after TAVI. The existing literature on anticoagulation after bioprosthetic valve replacement was thoroughly reviewed, including the most recent American College of Cardiology/American Heart Association 2017 guidelines for management of valvular disease, which is based on sparse, nonrandomized retrospective data...

BACKGROUND: Coronary artery disease (CAD) and degenerative aortic stenosis often coexist. However, the impact of CAD and its management on the prognosis after transcatheter aortic valve implantation (TAVI) remains uncertain. We sought to evaluate the impact of obstructive CAD, SYNTAX score (Ss), and percutaneous coronary intervention (PCI) prior to TAVI on short-term outcome. METHODS: Overall, 896 patients who underwent TAVI after heart team decision was included...

The relationship between cardiac rhythm and adverse events after transcatheter aortic valve implantation (TAVI) remains unclear. To compare the prognostic impact of preexisting atrial fibrillation (AF) and new-onset AF (NOAF) after TAVI, we assessed 1,124 patients (846 with sinus rhythm [SR], 49 with NOAF, and 229 with preexisting AF) who underwent TAVI with a balloon-expandable valve from October 2013 to April 2016. The incidences of all-cause death and rehospitalization for heart failure (HF) were retrospectively evaluated...

We describe an improvised technique during open surgery of inserting a transcatheter heart valve in the mitral position under very challenging circumstances. This is the first described use of the "extended collar" technique, which allowed implantation of a transcatheter heart valve in severe mitral valve annular calcification, into which a surgical valve could not safely be implanted. We believe that this technique is reproducible and may be helpful to other surgeons when faced with similar difficult circumstances...

OBJECTIVES: This study is the first report of 2 cases of HighLife (HighLife, Paris, France) implantation in humans. BACKGROUND: Transcatheter mitral valve implantation represents a promising approach to treating mitral regurgitation in patients at increased risk of perioperative mortality. The HighLife transcatheter mitral valve is a 2-component system. The valve is implanted in the mitral position and is anchored by interacting and then reaching an equilibrium position with a previously positioned subannular implant...

BACKGROUND: Severe mitral regurgitation is associated with impaired prognosis if left untreated. Using the devices currently available, transcatheter mitral valve repair (TMVr) remains challenging in complex anatomical situations. We report the procedural and 30-day results of the first-in-man study of the Edwards PASCAL TMVr system. METHODS: In this multicentre, prospective, observational, first-in-man study, we collected data from seven tertiary care hospitals in five countries that had a compassionate use programme in which patients underwent transcatheter mitral valve repair using the Edwards PASCAL TMVr system...

BACKGROUND: New-generation (NG) valves for transcatheter aortic valve implantation (TAVI) has recently been widely used in real-world practice, yet its comparative outcomes with early-generation (EG) valves remain under-explored. METHODS: An electronic literature search using PUBMED and EMBASE was conducted from inception to April 2017 for matched-cohort studies. Articles that compared the outcomes of NG vs. EG valves post TAVI with at least one of the following clinical outcome reported were included: all-cause mortality, major or life-threatening bleeding, major vascular complications (MVC), significant (more than moderate) paravalvular regurgitation (PVR), cerebrovascular events, significant (stage 2 or 3) acute kidney injury (AKI) and new permanent pacemaker implantation (PPI) that occurred either in-hospital or within 30-days...

Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...
