Transcatheter aortic valve replacement has shown important benefits but one of its biggest challenges is showing its safety and efficacy at followup in low risk patients. At present we have 2-year data from the Evolute Low Risk, but the we lack information at longer followup. The study looked at 3-year followup of the Evolute Low<a href="https://solaci.org/en/2023/05/03/evolute-low-risk-at-3-years-promising-outcomes/" title="Read more" >...</a>
Coronary artery disease (CAD) coexists with aortic stenosis in about half the patients who suffer the latter. These patients receiving antiplatelet therapy are at a higher risk of periprocedural bleeding—one of the most frequent complications in patients who undergo transcatheter aortic valve replacement (TAVR). One way of limiting the risk for bleeding is choosing the<a href="https://solaci.org/en/2023/04/17/clinical-impact-of-coronary-artery-disease-on-results-after-tavr/" title="Read more" >...</a>

One of the challenges that transcatheter aortic valve replacement (TAVR) continues to face is percutaneous access closure with percutaneous closure systems (PCS). However, several systems have been developed, either by plug—such as the MANTA system—or by suture (SU)—such as the ProStar and ProGlide systems. Both of these have been tested in different analyses, but to<a href="https://solaci.org/en/2023/04/12/percutaneous-access-closure-in-tavr-are-devices-similar/" title="Read more" >...</a>
Prosthesis-patient mismatch (PPM) was initially proposed by Rahimtoola and reintroduced by Pirabot. PPM is the indexed effective orifice area in relation to body surface area, cutoff value being 0.85 cm2/m2, and <0.70 cm2/m2for obese patients. PPM is considered moderate if indexed effective orifice area is 0.65-0.85 cm2/m2 and severe when <0.65 cm2/m2 Research studies on surgical prosthesis have<a href="https://solaci.org/en/2023/04/05/prosthesis-mismatch-in-tavr-its-real-impact/" title="Read more" >...</a>
Edge-to-edge treatment has proven to be a safe and effective technique in follow-up, decreasing mortality and hospitalizations for heart failure when a good result is achieved. The MitraScore was developed to assess the outcome at the end of the procedure. In that sense, results <3 represent mild mitral regurgitation, which would be related to lower<a href="https://solaci.org/en/2023/03/31/mitrascore-what-does-the-final-result-of-edge-to-edge-treatment-of-mitral-regurgitation-provide/" title="Read more" >...</a>
Amyloidosis is a systemic disease that affects different organs and impairs their function. Recent studies with magnetic resonance imaging (MRI) have shown that between 13% and 16% of patients who undergo transcatheter aortic valve replacement (TAVR) have amyloidosis. A review of four studies showed that mortality at 20 months was twice as high when amyloidosis<a href="https://solaci.org/en/2023/03/28/amyloidosis-and-tavr-does-this-disease-have-an-impact/" title="Read more" >...</a>
At present, surgical aortic valve replacement (SAVR) uses bioprostheses. However, when these fail, we are presented with a great challenge, seeing as repeat SAVR involves a higher risk. In this context, valve-in-valve (V-in-V TAVR) has surged as a very attractive alternative. Bioprosthesis fracture (BPF) is a new interesting strategy that has shown lower gradient and<a href="https://solaci.org/en/2023/03/28/when-is-it-best-to-fracture-a-bioprosthesis-in-tavr/" title="Read more" >...</a>
At present, the transfemoral access (TFA) is the preferred approach when it comes to transcatheter aortic valve replacement (TAVR). However, 5 to10% of PAD patients present tortuous iliac anatomy and calcification, aortic aneurysms or prior peripheral intervention, which makes it impossible. There are several alternatives to approach these patients: 1) TFA associated to peripheral PCI<a href="https://solaci.org/en/2023/03/17/tavr-vascular-access-in-patients-with-peripheral-artery-disease-1-year-outcomes/" title="Read more" >...</a>
At present, transcatheter aortic valve replacement (TAVR) has become the gold standard in the US, regardless surgical risk. The current ACC and AHA guidelines recommend that a Heart Team make the decision for 65 to 80-year-old patients with aortic stenosis. In low risk patients, fast recovery and short term benefits of TAVR should be weighed<a href="https://solaci.org/en/2023/03/08/acc-2023-tavr-in-low-risk-patients-3-year-outcomes/" title="Read more" >...</a>
