BACKGROUND: Nonagenarians are mostly denied from different therapeutic strategies due to high preoperative risk. We present the results of nonagenarians with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). METHODS: Our retrospective analysis include baseline and procedural data along with clinical outcome. Clinical follow-up was performed in all patients after TAVR. RESULTS: Out of 689 patients, 33 nonagenarians with a mean age of 90...

A 80-year-old man was admitted to catheterization room for an acute infero-lateral ST-elevation myocardial infarction (STEMI). Coronary angiography showed a thrombotic occlusion of the second left marginal branch, and normal other coronary arteries. The thrombo-embolic mechanism of the STEMI, and the infectious context in this patient who had had a transcatheter aortic valve implantation (TAVI) two months earlier, led us to suspect a bioprosthesis endocarditis. It was confirmed by transthoracic and transoesophageal echocardiography, which showed an aortic-mitral curtain abscess and aortic bioprosthesis vegetations, associated to Enterococcus faecalis bacteriemia...

OBJECTIVES: The transapical approach provides concurrent surgical access to the mitral and the aortic valves, the root of the aorta and the left atrium. We previously showed the feasibility of transapical cardioscopic (TAC) surgery in a non-survival porcine model. However, reproducibility and feasibility of ring implantation using TAC have not been reported. Therefore, in this study, we hypothesized that implantation of a mitral annuloplasty ring can be feasibly and safely carried out endoscopically via the apex of the heart...

Background: Transcatheter aortic valve replacement (TAVR) has been shown safe and feasible in patients with bicuspid aortic valve (BAV) morphology. Evaluation of inter-ethnic differences in valve morphology and function and aortic root dimensions in patients with BAV is important for the worldwide spread of this therapy in this subgroup of patients. Comparisons between large European and Asian cohorts of patients with BAV have not been performed, and potential differences between populations may have important implications for TAVR...

Aims: Transthyretin cardiac amyloidosis (ATTR-CA) has been reported in patients with aortic stenosis (AS) but its prevalence and phenotype are not known. We examine elderly patients with severe symptomatic AS undergoing transcatheter aortic valve replacement (TAVR) and determine the prevalence and phenotype of ATTR-CA non-invasively. Methods and results: We performed technetium-99m pyrophosphate (99mTc-PYP) cardiac scintigraphy prospectively on patients who underwent TAVR, to screen for ATTR-CA...

BACKGROUND: As the indications for transcatheter aortic valve implantation (TAVI) have expanded, so to have the demands on interventionists to allow as many patients to access this technology as possible. METHODS: We retrospectively reviewed our TAVI database for patients who had received a 29mm SAPIEN 3 valve despite having an annular area greater than the manufacturer-recommended upper limit of 683mm(2), as determined by multi-detector computed tomography (MDCT)...

A patient presented for an elective transcatheter aortic valve replacement with temporary transvenous pacing (TVP) wires placement per protocol. On postoperative day 1, the patient remained stable, so the wires were subsequently removed, after which the patient acutely decompensated, with transthoracic echocardiography revealing pericardial effusion. Emergent pericardiocentesis was performed, and a pericardial drain was placed. Three days later, the drain was removed; again, the patient acutely decompensated, requiring another emergent pericardiocentesis...

OBJECTIVES: To determine the prevalence and factors associated with persistent pulmonary hypertension (PH) following transcatheter aortic valve replacement (TAVR) and its relationship with long-term mortality. METHODS: Consecutive patients who underwent TAVR from July 2011 through January 2016 were studied. The prevalence of baseline PH (mean pulmonary artery pressure ≥25 mm Hg on right heart catheterisation) and the prevalence and the predictors of persistent≥moderate PH (pulmonary artery systolic pressure (PASP)>45 mm Hg on 1 month post-TAVR transthoracic Doppler echocardiography) were collected...

BACKGROUND: Despite a lack of clear evidence, current European guidelines recommend antiplatelet therapy after transcatheter aortic valve replacement (TAVR). Recent investigations suggest that bioprosthesis thrombosis after TAVR is not uncommon and may be prevented by anticoagulation, but not by antiplatelet therapy. AIMS: The study objective was to assess the impact of the antithrombotic regimen on post-TAVR early haemodynamics. METHODS: Patients eligible for TAVR with an Edwards SAPIEN 3 valve were included in this prospective observational study...

The success and continued rapid clinical integration of transcatheter valve technologies relies on imaging modalities to guide safe and effective device deployment. In particular, cardiac imaging, using both echocardiography and CT, is an integral resource for the multidisciplinary team. These modalities can provide valuable insight for the proceduralist at each stage of transcatheter-based valve insertion, as they can be used reliably to define the anatomy of interest and its relationship to surrounding structures, determine accurate device sizing, assess patients for valve-in-valve procedures, and screen for adverse features or procedural contraindications...

Enlarging or "cracking" a surgical stented bioprosthetic valve during valve-in-valve transcatheter aortic valve implantation (TAVI) increases orifice area, reducing transvalvular energy losses. We demonstrate that TAVI with valve cracking can be used to treat paravalvular leak (PVL) while providing optimal aortic valve physiology. A 61-year-old woman with a history of aortic valve replacement with a stented bioprosthesis presented with heart failure. Transthoracic echocardiography revealed severe prosthetic aortic valve stenosis with PVL and severe regurgitation...

Left atrial appendage (LAA) closure prevents thromboembolic risk and avoids lifelong anticoagulation due to atrial fibrillation (AF). Nowadays, AtriClip, a modern epicardial device approved in June 2010, allows external and safe closure of LAA in patients undergoing cardiac surgery during other open-chest cardiac surgical procedures. Such a surgical approach and its epicardial deployment differentiates LAA closure with AtriClip from percutaneous closure techniques such as Watchman (Boston Scientific, Marlborough, MA, USA), Lariat (SentreHEART Inc...

A 62-year old male with pulmonary fibrosis and aortic valve stenosis underwent TAVI (Corevalve Evolut XL 34 mm) in the build-up for lung transplantation (LuTx). Following post-dilation for a large annular perimeter, moderate paravalvular aortic regurgitation (AR) was observed. After 6 weeks, he was admitted to the ICU with respiratory failure(A). TTE demonstrated residual mild AR (based on a small excentric paravalvular AR jet, <10% circumferential extent, pressure half-time was not reliably measured) and together with borderline elevated NT-pro-BNP, the consultant cardiologist authorized LuTx listing...

BACKGROUND: The prevalence of low flow low gradient (LFLG) severe aortic stenosis (AS) may be overrated due to underestimation of stroke volume in two-dimensional (2D) echocardiography. The implications of 3D imaging on stroke volume calculation for AS classification have not been elucidated. Integrating multi-detector computed tomography (MDCT) and Doppler data may improve diagnostic accuracy in patients with LFLG AS. METHODS: A total of 186 patients with severe AS evaluated for transcatheter aortic valve replacement were classified according to indexed stroke volume (SVI, cut-off 35mL/m(2)) and mean transaortic pressure gradient (cut-off 40mmHg)...

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)...
