Data from a great Australian registry of nearly 250,000 people with a 5-year follow-up, presented at the European Society of Cardiology (ESC) Congress 2019 in Paris and simultaneously published in J Am Coll Cardiol, suggest that mortality due to severe aortic stenosis is similar to that due to moderate aortic stenosis. These data warn us<a href="https://solaci.org/en/2019/09/10/esc-2019-how-benign-is-moderate-aortic-stenosis/" title="Read more" >...</a>
For the first time, this long term observational study on a large cohort of contemporary patients with aortic stenosis (AS), has shown syncope is an underestimated threat, associated with worse prognosis after surgical aortic valve replacement (SAVR). It is interesting to note that other symptoms or early signs of AS that will normally indicate SAVR<a href="https://solaci.org/en/2019/02/11/un-underestimated-symptom-of-aortic-stenosis/" title="Read more" >...</a>
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;<a href="https://solaci.org/en/2018/10/30/what-should-we-use-for-the-functional-assessment-of-coronary-lesions-in-severe-aortic-stenosis/" title="Read more" >...</a>
Pressure loss vs. flow curves offer a fundamental synthesis of fluids dynamics in describing aortic valve physiopathology. Severe aortic stenosis is not just an orifice (as suggested by Gorlin) or a segment that offers dynamic resistance. However, once a new transcatheter valve has been implanted, it will behave purely as a resistor.

Courtesy of Dr. Carlos Fava. Transcatheter aortic valve replacement (TAVR) has been proven to reduce mortality and improve the quality of life of patients with pure severe aortic stenosis (PAS). However, there is a significant number of patients who experience mixed aortic stenosis associated with moderate/severe aortic regurgitation (MAS). These subjects were excluded from the PARTNER<a href="https://solaci.org/en/2017/12/12/tavr-in-patients-with-pure-vs-mixed-aortic-stenosis-benefits-and-evolution/" title="Read more" >...</a>
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.
Courtesy of Dr. Carlos Fava One of the present challenges of TAVR is bicuspid aortic valve stenosis (AS), since it presents a different distribution and structure, associated to greater and more irregular calcification. There are only small series of devices and their use is still controversial. The study analyzed 561 patients with severe bicuspid<a href="https://solaci.org/en/2017/04/27/bicuspid-aortic-valve-stenosis-still-challenging-for-tavr/" title="Read more" >...</a>
