A study by the Northern New England Cardiovascular Disease Group Consortium recently published online identified all patients with aortic valve stenosis treated with surgical or transcatheter aortic valve replacement between 2016 and 2022 in Maine, New Hampshire, and Vermont (USA). These patients were divided for analysis into three age groups: under 65 years old, 65...
Degenerative aortic stenosis (AS) is the most common valve condition. A significant number of AS patients presents a small aortic annulus (SAA), especially women. Treating this group of patients remains challenging, seeing as they have a high incidence of suboptimal hemodynamic results. Despite the development of TAVR (transcatheter aortic valve replacement), the current guidelines do...
Data from recent observational randomized studies suggest that most patients with asymptomatic severe aortic stenosis will eventually receive an indication for valve replacement. Mortality in this “asymptomatic” population is caused not only by sudden death, but also by cardiac death. Early intervention may prevent these deaths as a consequence of aortic stenosis symptoms. Researchers...
Courtesy of Dr. Carlos Fava. Aortic valve calcification and its resulting stenosis leads to changes in left ventricle hemodynamics, producing diffuse ischemia followed by inflammation, increased extracellular matrix, necrosis, and later, diffuse fibrosis. At present, with magnetic resonance imaging (MRI) we can analyze ventricular architecture and its function by detecting fibrosis (LGE) and its volume...
This small randomized study heated the debate about when to intervene aortic stenosis (AS). Putting off surgical valve replacement (SAVR) in patients with asymptomatic AS and waiting for symptom onset with conservative care increased periprocedural risk and all cause cardiovascular death. This study presented by Dr Duk-Hyun Kang during AHA 2019 scientific sessions (simultaneously published...
This systematic analysis measured intracoronary pressure in different phases of the cardiac cycle and flow velocity in patients with severe aortic stenosis and coronary artery disease, who were scheduled for transcatheter aortic valve replacement (TAVR). The aim was to determine the impact of aortic stenosis on: 1) flow, at different phases; 2) hyperemic coronary flow;...
Read articles on the main presentations of the third day of SOLACI-CACI 2017 Congress. See the presentation by Dr. Daniel Weilenmann, entitled “Is the PCI risk higher in patients with severe Aortic Stenosis? How can we reduce the risk?“. We are interested in your opinion. Please, leave your comments, thoughts, questions, etc., below. They will be most welcome.
This work studies the natural history of aortic stenosis and the optimal timing to intervene elderly patients with asymptomatic severe aortic stenosis. This disease is increasingly misdiagnosed in the elderly population, and this goes hand in hand with enhanced therapeutic options. Prior studies on the natural history of this disease were made on...
Original Title: Natural history, diagnostic approaches, and therapeutic strategies for patients with asymptomatic severe aortic stenosis. Reference: Généreux P et al. J Am Coll Cardiol. 2016; Epub ahead of print. Given that transcatheter aortic valve replacement (TAVI) is now being prescribed to lower risk patients, some wonder whether it is time to study the benefit...
