La reparación de la válvula mitral con Mitraclip es segura en pacientes de alto riesgo

Mitral Valve Repair in Patients with Cardiac Failure

The mitral valve is a complex apparatus dependent on left atrium and left ventricle functionality. Dilation of these cavities might affect mitral annulus morphology and lead to valve dysfunction, generating mitral regurgitation (MR). This type of MR has been called functional, since leaflets and tendinous chordae do not present lesions themselves; instead, they malfunction ‘secondary’<a href="https://solaci.org/en/2018/10/01/mitral-valve-repair-in-patients-with-cardiac-failure/" title="Read more" >...</a>

Debris Captured by SENTINEL Devices Result Different across Different Valves

The idea behind this study is that debris can be captured in all patients during TAVR, even though we still ignore which patients would benefit more from this device. Tissue particles captured by the SENTINEL during TAVR vary from valve to valve, according to this new analysis. There are differences in size and number of<a href="https://solaci.org/en/2018/09/19/debris-captured-by-sentinel-devices-result-different-across-different-valves/" title="Read more" >...</a>

Surgical Redo Mitral Valve Replacement vs. Valve-in-Valve in Failed Bioprosthetic Valves

Despite their higher surgical risk, patients who underwent transcatheter mitral valve replacement (TMVR) presented 1-year mortality rates similar to those of patients who had redo surgical mitral valve replacement for bioprosthetic valve failure. At one month, echocardiographic findings were similar; however, at one year, patients who underwent TMVR presented a gradient increase that had no<a href="https://solaci.org/en/2018/09/18/surgical-redo-mitral-valve-replacement-vs-valve-in-valve-in-failed-bioprosthetic-valves/" title="Read more" >...</a>

Gradient vs. Flow to Determine Aortic Valve Stenosis Severity before and after TAVR

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.

La post-dilatación en el Valve in Valve presenta mejoría hemodinámica

Post-Dilation in Valve-in-Valve Implantation Offers Hemodynamic Improvement

Courtesy of Dr. Carlos Fava. A significant number of patients present severe aortic stenosis and undergo surgery with 19-to-21-mm bioprostheses. These patients frequently evolve with high gradients and receive Valve-in-Valve (ViV) implantation. In about a third of patients with high post-procedural gradient (≥20 mmHg), this has been associated with poor outcomes. This study analyzed 30 patients who underwent<a href="https://solaci.org/en/2018/07/16/post-dilation-in-valve-in-valve-implantation-offers-hemodynamic-improvement/" title="Read more" >...</a>

Differences in Debris Captured According to Valve Type

During valve replacement, cerebral protection systems may capture debris in up to 99% of all patients. In over half of them, these particles are &gt;1 mm. The particles captured during procedures in which Evolut R or Lotus valves were used were more and larger compared with those captured with the Sapien balloon-expandable valve.

Treating Tricuspid and Mitral Valves with MitraClip Improves Quality of Life

Courtesy of Dr. Carlos Fava. It has been shown that significant tricuspid regurgitation (TR) is an independent predictor of bad evolution in the presence of  mitral valve disease. Its prevalence is not low, reaching up to 50% in patients undergoing surgery for mitral regurgitation (MR). This study included 61 patients with significant TR and MR. 27<a href="https://solaci.org/en/2018/07/02/treating-tricuspid-and-mitral-valves-with-mitraclip-improves-quality-of-life/" title="Read more" >...</a>

The Largest Registry on the ACURATE neo Valve

Transcatheter aortic valve replacement (TAVR) using the ACURATE neo device depends, largely, on correct patient selection and appropriate oversizing. The individual anatomy of each patient, namely periannular and aortic root calcification, must be taken into account. The ACURATE neo valve (Symetis/Boston, Ecublens, Switzerland) is a new-generation self-expanding valve characterized by a stent design shaped as an X<a href="https://solaci.org/en/2018/06/15/the-largest-registry-on-the-acurate-neo-valve/" title="Read more" >...</a>

EuroPCR 2018 | NOTION: Good TAVR Durability Compared with Surgically-Implanted Valve in Low-Risk Patients

Several studies are defining the role of transcatheter aortic valve replacement (TAVR) in patients with low surgical risk. One of the main concerns for this population, whose life expectancy is much longer, has to do with TAVR durability compared with a surgically-implanted biological valves.

Bicuspid Valves Do Not Increase Mortality in TAVR

The frequency of bicuspid aortic valves (BcAV) are around 1%, but in 60+ patients it is associated to severe aortic stenosis. Even though surgery is the standard treatment, TAVR is the “off label” indication in high risk patients. &nbsp; BcAV presents differences with tricuspids given that it is more elliptic, has asymmetric calcification and more<a href="https://solaci.org/en/2018/05/02/bicuspid-valves-do-not-increase-mortality-in-tavr/" title="Read more" >...</a>
