Patients with low-flow, low-gradient severe symptomatic aortic stenosis associated with severe impairment of the left ventricular systolic function have shown acceptable outcomes after transcatheter aortic valve replacement (TAVR), according to the multicenter TOPAS-TAVI registry, which demonstrated a relatively low 30-day mortality rate. Considering the very high risk presented by this population involved, a 30-day…
Permanent Pacemaker Predictors with SAPIEN 3
The aim of this study was to identify permanent pacemaker (PPM) predictors after transcatheter aortic valve replacement (TAVR) with last generation balloon expandable valve Edwards SAPIEN 3. The new conduction disturbances requiring PPM are one of the biggest concerns after TAVR, and their predictors have not yet been defined. 229 patients undergoing TAVR…
Transcaval Access: Another Alternative to Femoral Access Counterindication
For TAVR eligible patients (transcatheter aortic valve replacement) with femoral access counterindication, a new access site, extra thoracic yet percutaneous, may offer an alternative. This consists of reaching the abdominal aorta through the vena cava. With this technique the operator enters the abdominal aorta through the vena cava by electrifying a guidewire, advancing a…
Coronary Lesions After TAVR: Severity May Be Modified
Courtesy of Dr. Carlos Fava. Between 40% and 70% of patients undergoing transcatheter aortic valve replacement (TAVR) present coronary lesions. The fact that aortic stenosis affects how blockages act, and that, after stenosis correction, hemodynamic compromise for those same lesions may vary, has been consistently proven. Its management has not been determined yet. The study…
TAVR in Pure Aortic Insufficiency: Yes or No?
Courtesy of Dr. Agustín Vecchia. Surgery is the treatment of choice for patients with symptomatic aortic insufficiency and/or ventricular dilatation or decreased ventricular function. The broad implementation of transcatheter aortic valve replacement (TAVR) in patients with aortic stenosis, the emergence of new devices, and the experience acquired by operators have brought this treatment to off-label indications such…
TAVR: Transcarotid Access as a Valid Alternative
Courtesy of Dr. Carlos Fava. Transfemoral access is the first choice for transcatheter aortic valve replacement (TAVR). However, this approach is not feasible for a progressively larger number of patients, which establishes the need to search for alternative accesses. Between 2009 and 2014, this study enrolled 174 patients who underwent TAVR and were unsuitable for transfemoral…
Transapical and Transaortic TAVR: Valid Alternatives to the Transfemoral
Courtesy of Dr. Carlos Fava. The femoral approach has been the gold standard for the transcatheter aortic valve replacement procedure (TAVR); however, it is anatomically unsuitable for an important number of patients, and these require a different approach. At present, there is little evidence in support of the transapical or transaortic access sites as…
Local Anesthesia for TAVR Was Safe and Reduced Hospital Stays
A minimalist approach to transcatheter aortic valve replacement (TAVR) involving local anesthesia appears to have several advantages, according to this new meta-analysis. In addition to shortening times for procedures and lengths of stay in the critical care unit and hospital, lighter sedation may lower the need for transfusions or treatment with inotropes or vasopressors.…
TAVR or Surgery for Intermediate-Risk Patients? (GARY Registry)
New findings from the GARY (German Aortic Valve Registry) registry show that intermediate-risk patients with severe aortic stenosis presented significantly higher mortality at 1 year when treated with transcatheter aortic valve replacement (TAVR) rather than with conventional surgery. Results reflect everyday realities, which might include various bias tipping the scales towards one strategy or the…
Less than 20% of patients that could benefit from TAVR are receiving it
The introduction of transcatheter aortic valve replacement procedures (TAVR) seems to have increased the number of elderly patients hospitalized with severe aortic stenosis, as well as the number of interventions. However, less than one fifth of patients over 85 are intervened, according to a Canadian registry. Given the significant difference in mortality with TAVR,…
