JACC Cardiovascular Imaging has recently published a retrospective analysis including severe aortic stenosis patients (&lt; 1 cm&sup2;), with low gradient (mean aortic gradient Patients that had undergone dobutamine stress echocardiography (DSE) to distinguish pseudo aortic stenosis (n=49) were selected.

ACC 2024 | DEDICATE Trial: Transcatheter or Surgical Treatment of Aortic Valve Stenosis

In recent years, TAVR has been increasingly used; however, when it comes to younger, lower risk patients, its use is still challenged.&nbsp; In this context, there is limited information and we lack randomized studies on “real world” cohorts.&nbsp; The DEDICATE randomized 1.414 patients over 65 with severe symptomatic aortic stenosis. 701 of these patients received<a href="https://solaci.org/en/2024/04/11/acc-2024-dedicate-trial-transcatheter-or-surgical-treatment-of-aortic-valve-stenosis/" title="Read more" >...</a>

Temporal Trends in Transcatheter Aortic Valve Replacement for Isolated Severe Aortic Stenosis

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<a href="https://solaci.org/en/2024/04/11/temporal-trends-in-transcatheter-aortic-valve-replacement-for-isolated-severe-aortic-stenosis/" title="Read more" >...</a>

TAVR in the Different Types of Aortic Stenosis

Aortic stenosis (AS) is classified according to gradient into high flow and high gradient (D1), low flow-low gradient with reduced ejection fraction (D2), and paradoxical low flow-low gradient with conserved ejection fraction (D3). D3 AS is characterized by ≥50% ejection fraction, but with systolic volume index ≤35 ml/min.

Can Ultrasound Treat Aortic Stenosis?

Severe calcified aortic stenosis is a common condition that can currently be effectively treated with SAVR or TAVR. However, some patients, given comorbidities or anatomical characteristics, are not good candidates for these therapeutic alternatives.&nbsp; The non-invasive ultrasound therapy (NIUT) has surged as viable alternative. It claims ultrasound might act on calcified valves, and mobilize tissue<a href="https://solaci.org/en/2023/12/05/can-ultrasound-treat-aortic-stenosis/" title="Read more" >...</a>

Low Gradient, Normal Flow Aortic Stenosis: Changes in Quality of Life with TAVR

There is no question as regards the recommended treatment for symptomatic severe aortic stenosis, seeing as both transcatheter and surgical aortic valve replacement (TAVR and SAVR) have shown to significantly improve prognosis. This is despite the fact that there is still certain ambiguity around its characterization, which looks to define it according to hemodynamic severity<a href="https://solaci.org/en/2023/11/30/low-gradient-normal-flow-aortic-stenosis-changes-in-quality-of-life-with-tavr/" title="Read more" >...</a>

Untreated Aortic Stenosis: Associated Mortality and a Call to Attention

The progression of aortic stenosis has been extensively studied and is well-known. As observed, in its advanced stages, this condition entails high morbidity and a marked decrease in survival. Both North American and European guidelines recommend treatment when faced with severe valve disease. However, true severity can be difficult to determine due to discordant data,<a href="https://solaci.org/en/2023/11/13/untreated-aortic-stenosis-associated-mortality-and-a-call-to-attention/" title="Read more" >...</a>

Moderate Aortic Stenosis: We Should Start Assessing It More Thoroughly

Moderate aortic stenosis (MAS) encompasses a broader spectrum than severe aortic stenosis. However, its progression has not yet been fully elucidated. While there are reports suggesting that this condition is not as benign as initially believed, there is a need to consider early interventions in certain instances.

What Is the Prognosis of an Acute Myocardial Infarction in the Presence of Moderate Aortic Stenosis?

Aortic stenosis (AS) is a common condition that shares risk factors with coronary artery disease. Many patients can suffer from both diseases simultaneously, something that increases the risk of acute myocardial infarction in the presence of aortic stenosis. AS can cause ischemia even in the absence of coronary artery disease, due to ventricular hypertrophy, increased<a href="https://solaci.org/en/2023/07/12/what-is-the-prognosis-of-an-acute-myocardial-infarction-in-the-presence-of-moderate-aortic-stenosis/" title="Read more" >...</a>
