Assessment of successful valve reconstruction by intraoperative transesophageal echocardiography (TEE)

1986

In 17 patients (10 patients with mitral insufficiency, 5 patients with tricuspid regurgitation, 2 patients with mitral stenosis) the result of valve reconstruction was evaluated by intraoperative two-dimensional transesophageal contrast-echocardiography (TEE). Therefore, 1–2 cc of an agitated contrast-medium (GelifundolR) were injected into the left or right ventricle. The result of reconstruction was assessed by the extent of regurgitant microbubbles into the left or right atrium. A successful valve repair could be demonstrated in 15 patients without or with only minimal regurgitation of contrast-fluid. In one patient residual severe mitral insufficiency after valve reconstruction could on…

Lipoprotein(a) and aortic valve stenosis: A casual or causal association?

2022

Abstract Aims This review aims to provide an update of available methods for imaging calcification activity and potential therapeutic options. Data Synthesis: Aortic valve calcification represents the most common heart valve condition requiring treatment among adults in Western societies. No medical therapies are proven to be effective in treating symptoms or reducing disease progression. Therefore, surgical or transcatheter aortic valve replacement remains the only available treatment option. Elevated circulating concentrations of lipoprotein(a) is strongly associated with degenerative aortic stenosis. This relationship was first observed in prospective observational studies, and the causa…

The impact of del Nido cardioplegia solution on blood morphology parameters

2021

Background: Crystalloid cardioplegic solutions are believed to reduce hemoglobin significantly and increase the transfusion rate. However, recent reports indicate that the del Nido cardioplegia may preserve blood morphology parameters. Methods: In “The del Nido versus cold blood cardioplegia in aortic valve Replacement” trial patients undergoing aortic valve replacement were randomized into the del Nido (DN) or cold blood cardioplegia (CB) group. For the subanalysis, patients who underwent blood transfusions were excluded from the study. Red blood cell (RBC) count, hemoglobin, white blood cell (WBC) count and platelet (PLT) count were measured before the surgery, 24-, 48-, and 96 hours post…

How should I treat a DeBakey type I acute aortic dissection four weeks after transcatheter aortic valve implantation in an old, fragile patient?

Minimally invasive aortic valve surgery

2016

Aortic valve disease is a prevalent disorder that affects approximately 2% of the general adult population. Surgical aortic valve replacement is the gold standard treatment for symptomatic patients. This treatment has demonstrably proven to be both safe and effective. Over the last few decades, in an attempt to reduce surgical trauma, different minimally invasive approaches for aortic valve replacement have been developed and are now being increasingly utilized. A narrative review of the literature was carried out to describe the surgical techniques for minimally invasive aortic valve surgery and report the results from different experienced centers. Minimally invasive aortic valve replacem…

A multicentre European registry to evaluate the Direct Flow Medical transcatheter aortic valve system for the treatment of patients with severe aorti…

2016

Aims Our aim was to assess the clinical outcomes of the Direct Flow Medical Transcatheter Aortic Valve System (DFM-TAVS), when used in routine clinical practice. Methods and results This is a prospective, open-label, multicentre, post-market registry of patients treated with DFM-TAVS according to approved commercial indications. Echocardiographic and angiographic data were evaluated by an independent core laboratory and adverse events were adjudicated and classified according to VARC-2 criteria by an independent clinical events committee. The primary endpoint was freedom from all-cause mortality at 30 days post procedure. Secondary endpoints included procedural, early safety and efficacy en…

Incidence, Predictive Factors, and Prognostic Impact of Silent Atrial Fibrillation After Transcatheter Aortic Valve Implantation.

2018

New onset atrial fibrillation post-transcatheter aortic valve implantation (TAVI) is common and is associated with adverse outcomes. However, silent atrial fibrillation (AF) is poorly documented in the context. This study sought to evaluate the incidence, predictive factors, and prognostic value of Silent AF post-TAVI. All the consecutive patients with TAVI were prospectively analyzed by continuous electrocardiogram monitoring≥48 hours after implantation. Silent AF was defined as asymptomatic episodes lasting at least 30 seconds. The population was divided into 3 groups: history of AF, no-AF, and silent AF. Among the 206 patients implanted with TAVI, 19 (16.1%) developed silent AF. Compared…

TAVI imaging: over the echocardiography

2020

Aortic valve stenosis (AS) is a common valvular heart disease. Recently, transcatheter aortic valve implantation (TAVI) has changed the treatment of severe AS in elderly patients with contraindications to traditional surgical replacement. Echocardiography is conventionally used as the first imaging modality to assess the presence and severity of AS and to provide anatomical and functional information. Nowadays, imaging techniques play a crucial role in the planning of TAVI to define suitable candidates. Computed tomography (CT) is essential to display the anatomy of the aortic valve complex (including aortic annulus, Valsalva sinuses, coronary arteries ostia, sinotubular junction), thoracoa…

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…
