12‐Month outcomes of transcatheter tricuspid valve repair with the PASCAL system for severe tricuspid regurgitation
2021
Objectives We investigated the durability of tricuspid regurgitation (TR) reduction and the clinical outcomes through 12 months after transcatheter tricuspid valve repair (TTVr) with the PASCAL Transcatheter Valve Repair System. Background TTVr has rapidly developed and demonstrated favorable acute outcomes, but longer follow-up data are needed. Methods Overall, 30 patients (age 77 ± 6 years; 57% female) received PASCAL implantation from September 2017 to May 2019 and completed a clinical follow-up at 12 months. Results The TR etiology was functional in 25 patients (83%), degenerative in three (10%), and mixed in two (7%). All patients had TR severe or greater (massive or torrential in 80%)…
Feasibility of a MPR-based 3DTEE guidance protocol for transcatheter direct mitral valve annuloplasty.
2020
Objectives Several interventional approaches have been established for the treatment of severe mitral regurgitation (MR) in patients at elevated risk for surgery. Direct annuloplasty is a relatively novel option in transcatheter mitral valve repair dedicated to reverse pathology in specific subsets of MR. With regard to echocardiographic guidance, this procedure presents with higher efforts in comparison with edge-to-edge therapy to enable safe and exact positioning of the device's anchors; evidence on optimal peri-interventional imaging is sparse. We tested a specific 3D-echo-guidance protocol implementing single-beat multiplanar reconstruction (MPR) and evaluated its feasibility. Methods …
Cost effectiveness of aortic valve therapies: a systematic review of the literature
2022
Background: Systematic review on the cost effectiveness of transcatheter aortic valve implantation (TAVI) to standard aortic valve replacement and medical management in high-risk elderly patients with severe aortic stenosis. Evidenced based systematic reviews are the core methodologies in health economics for evaluating cost effectiveness and medical effectiveness. Clarity and transparency of these reports can help to provide health care interventions accurately and reliably. Methods: In accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses, a systematic review on current literature for cost-effectiveness of TAVI, standard aortic valve replacement, and medical m…
Mitral valve therapy still surgical?
2015
Mitral regurgitation (MR) is the second most common valvular heart disease after aortic valve stenosis. With increased understanding of the heterogenic pathophysiology of MR, cardiac surgeons have developed various techniques that increase the likelihood of successful mitral valve repair (MVR). Nowadays, a rate of repair >90% may be reached in some mitral valve reference centres. In recent years, the introduction of transcatheter mitral valve intervention techniques has opened up new frontiers in mitral therapy, specifically in patients at high risk for standard surgery. Current percutaneous technologies for MVR have been developed on the basis of some of the surgical principles. Based on c…
Differential Prognostic Value of Galectin-3 According to Carbohydrate Antigen 125 Levels in Transcatheter Aortic Valve Implantation
2019
Galectin-3 (Gal-3) and carbohydrate antigen 125 (CA125) have been associated with adverse outcomes after transcatheter aortic valve implantation (TAVI). Experimental data have suggested a potential molecular interaction. Therefore, we assessed the association of Gal-3 and CA125 with prognosis after TAVI.A total of 439 patients were enrolled. The primary endpoint was a composite of all-cause mortality or readmission for worsening heart failure after TAVI.The primary endpoint occurred in 16.4%. Gal-3 was dichotomized at ≥ 8.71 ng/mL into elevated and not elevated. Gal-3 was elevated in 31.9% and was associated with a higher risk of the primary endpoint (25% vs 12.4%, HR, 2.26; P.001). After m…

Aortic valve and vascular calcium score in pre-TAVI CT: correlation with early post-procedural complications
2023
Abstract Purpose The aim of our study was to evaluate the prevalence of early complications after Transcatheter Aortic Valve Implantation (TAVI) and their correlation with the Calcium Score (CS) of the aortic valve, aorta and ilio-femoral arteries derived from pre-procedural computed tomography (CT). Materials and methods We retrospectively reviewed 226 patients (100 males, mean age 79.4 ± 6.7 years) undergoing 64-slice CT for pre-TAVI evaluation from January 2018 to April 2021. The population was divided into CS quartiles. Results Overall, 173 patients underwent TAVI procedure, of whom 61% presented paravalvular leak after the procedure, 28% presented bleeding or vascular complications, 25…
Association of transcatheter direct mitral annuloplasty with acute anatomic, haemodynamic, and clinical outcomes in severe mitral valve regurgitation.
2020
Abstract Aims Several approaches for transcatheter mitral valve repair for functional mitral valve regurgitation are established. Interventional direct annuloplasty is a novel trans‐venous, trans‐septal approach. While feasibility was proven recently, knowledge on its influence on cardiac dimensions, pressures, biomarkers, and clinical outcomes is sparse. Methods and results Patients consecutively treated with direct annuloplasty‐only procedures between December 2015 and April 2018 were included in this monocentric analysis. Echocardiographic measurements, biomarker levels, clinical status [New York Heart Association (NYHA) class and 6 min walk test] were assessed at baseline, at discharge,…
Immunoglobulin G4-Related Aortitis and Severe Aortic Valve Stenosis Treated With Transcatheter Aortic Valve Replacement and Immunosuppression.
2021
Abstract IgG4-related disease is an immune-mediated fibro-inflammatory disorder with multisystemic involvement. Aortitis and peri-aortitis are the most common cardiovascular manifestations of the disease. We present the case of a 65-year-old man with symptomatic severe aortic stenosis and concomitant IgG4 aortitis. The diagnosis was confirmed by IgG4 serum levels, positive positron emission computed tomography (PET-CT) scans, and pathology from mediastinal dissection. Surgical aortic valve replacement (SAVR) was unfeasible owing to extensive mediastinal fibrosis, and transcatheter aortic valve replacement (TAVR) was successfully performed. As ascending aorta access for SAVR in IgG4 aortitis…
TCT-43 First-in-human experience of a novel transradial device for embolic deflection during transcatheter aortic valve replacement
2018
The average stroke rate in contemporary transcatheter aortic valve replacement (TAVR) studies is 4.4%. The majority of the TAVR studies are non-randomized registries, hence, neurological outcomes may be underreported. Over 50% of all TAVR related strokes occur during the procedure or on the same day
