Contained Annulus Rupture after TAVR: What Should We Do?

Contained Annulus Rupture after TAVR: What Should We Do?

Courtesy of Dr. Carlos Fava. Aortic annulus rupture is a catastrophic event that presents in nearly 0.9% of cases, but there is another entity called contained annulus rupture, associated to oversized devices and annulus calcification and diagnosed with CT angiography, with up to 5% frequency. 1602 patients from the ENCORE registry were analyzed. 21 of

Self-Expanding Valve vs. Balloon-Expandable Valve, Randomized, Head to Head

The “arms race”among transcatheter valves has been vertiginous. By the time we received the mid- or long-term outcomes of studies focused on a given valve, we were already using its next generation in clinical practice. As a result, there is little information addressing which valve is the best. Nowadays, this “arms race” has reached a

Leaflet Thickening and Immobility in Evolut Low Risk

Leaflet thickening and immobility caused by thrombosis have been reported for both surgical and transcatheter bioprostheses. This phenomenon is diagnosed through hypoattenuation, thickening, and lack of motion, as observed through computed tomography (CT) imaging. The incidence and, especially, the clinical implications of this phenomenon remain unclear, but they are of great interest, particularly in a

Malignancies and Aortic Stenosis: Is TAVR Warranted?

This meta-analysis tells us that patients with active malignancies and severe aortic stenosis have a good evolution after transcatheter aortic valve replacement (TAVR), except for a higher rate of pacemaker implantation in the general population. These patients must not be limited to respite care only, at least as far as aortic stenosis is concerned. Short-term

Aligning Prosthetic Valves to Native Commissures: The Secret to Coronary Artery Obstruction?

Preventing coronary artery obstruction during transcatheter aortic valve replacement (TAVR) continues to be a challenge. There are techniques to prevent (or at least reduce) this from happening, which could be catastrophic. However, they all somehow fall into palliative care, that is, they will merely provide relief, rather than a cure.  Commissure overlapping and the resulting

In Search of the Optimal Depth for Self-Expandable Valves

Despite the use of the different imaging approaches to calculating implantation depth, optimal depth is reached only 30% of the time. Multiple imaging does not offer a uniform perspective and therefore influence reporting.  Basically, we do not have a clear idea of what constitutes optimal depth on a case by case basis and, what is

Does Surgeon (Instead of Operator) Experience Affect TAVR?

There is a correlation between the volume of conventional surgical aortic valve replacement procedures and better outcomes in transcatheter aortic valve replacement (TAVR), with higher 30-day and 1-year mortality in sites with lower volume. This is a probable indication that a good surgical team is complemented by a good hemodynamic team and, ultimately, a good


SURTAVI Follow-Up Completed with Good News

The assessment of all severe aortic stenosis patients at intermediate risk of the SURTAVI was finally completed, confirming inferiority against the traditional surgical replacement (SAVR) in hard points such as all-cause mortality and disabling stroke.  The aim of this study was to report SURTAVI 2-year outcomes (Surgical Replacement and Transcatheter Aortic Valve Implantation) and confirm

Aortic Valvuloplasty as a Bridge to TAVR: Are We Wasting Our Time?

Doing a balloon aortic valvuloplasty can be a good way to “buy” time before a transcatheter aortic valve replacement (TAVR), according to a registry to be published this week in J Am Coll Cardiol Intv. This study analyzed the database of a whole country to find out the incidence, predictors and outcomes of balloon aortic
