TAVR vs. the Least Invasive Surgically Implanted Valve

Rapid-deployment surgically implanted valves are designed to make a surgeons’ job faster and easier, compared with conventional bioprostheses, which require several stitches. These valves, which shorten surgical times, could compete with transcatheter-implanted valves (transcatheter aortic valve replacement, TAVR). The German Aortic Valve Registry analyzed 16,473 patients who underwent surgical aortic valve replacement with either a current-generation

The Best Anticoagulant Agent for AF After TAVR

Direct anticoagulant agents were associated with lower long-term mortality in patients with atrial fibrillation (AF) discharged after transcatheter aortic valve replacement (TAVR), compared with classic vitamin K antagonists. The purpose of this paper published in JACC Interv was to compare long-term results between classic vitamin K antagonists and novel direct anticoagulant agents in patients with

Es un hecho: la protección cerebral en TAVI logró demostrar que reduce el stroke y la muerte

Silent Stroke During TAVR and Early Cognitive Impairment

Silent stroke is common after transcatheter aortic valve replacement (TAVR). Co-morbidities such as diabetes or chronic renal failure, as well as procedural factors such as pre-dilation, increase the risk of silent stroke. While many events of silent stroke have an early effect on cognition, it is necessary to learn whether the impairment is sustained over

El estudio SOURCE 3 confirma los buenos resultados de la válvula SAPIEN 3 a un año de seguimiento

High Deployment: Also Trending with Balloon Expandable Valves

Conventional implantation of balloon expandable SAPIEN-3 results in a final 70:30 or 80:20 ratio of the valve in the aorta/left ventricular outflow tract. This comes with permanent pacemaker implantation rates of approximately 10%. Higher deployment might translate into lower rates of conduction abnormalities and pacemaker implantation.   The study compared a cohort of 1028 consecutive patients; 406

Cusp Overlap for Higher CoreValve Implantation

Implant depth greater than the length of the membranous septum is an independent predictor of permanent pacemaker implantation. Valve implantation 3 to 5 mm below the aortic annulus in a projection coaxial to the device is recommended. The problem is this is rarely in the annular plane of the valve. Ideal annular plane projection is

AAS vs Warfarin in Low Risk TAVR

We are still discussing the adequate antithrombotic scheme after transcatheter aortic valve replacement (TAVR). Additionally, we are treating a much wider array of patients ranging from low risk to inoperable.  And there is yet one more important point: hypo-attenuated leaflet thickening diagnosed by CT. We are still unaware of the impact they have on device


Coronary Access After TAVR: A Potential Problem Ahead

Coronary cannulation after transcatheter aortic valve replacement (TAVR) was unsuccessful in almost 10% of patients. This problem occurred almost exclusively in those who received a self-expanding valve. This study, recently published in JACC Cardiovasc Interv., was sought to investigate the feasibility of coronary ostia access after TAVR and describe potential predictors of coronary access impairment.

Should We Discontinue Anticoagulation Before TAVR?

Against what common sense dictates, continuing oral anticoagulation pre- and post- transcatheter aortic valve replacement (TAVR) is safe, according to this article soon to be published in JACC Interventions. There was no increase in hemorrhagic or vascular complications and, paradoxically, those who continued using anticoagulant agents received fewer transfusions that those who did not. A

La prudencia es buena consejera para decidir una transfusión en el TAVI

Transfusion in TAVR: Caution Is Best

Periprocedural red blood cell transfusion in transcatheter aortic valve replacement (TAVR) correlates with increased mortality and acute kidney injury. It also resulted an independent predictor of 30-day mortality, irrespective of bleeding and vascular complications.  The global trend that limits transfusion, in all procedures in general, has finally reached TAVR.  The multicenter registry TRITAVI (Transfusion Requirements
