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...
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...
Courtesy of Dr. Carlos Fava. Aortic valve calcification and its resulting stenosis leads to changes in left ventricle hemodynamics, producing diffuse ischemia followed by inflammation, increased extracellular matrix, necrosis, and later, diffuse fibrosis. At present, with magnetic resonance imaging (MRI) we can analyze ventricular architecture and its function by detecting fibrosis (LGE) and its volume...
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...
01- ECS Guidelines for COVID-19 Management One of the first statements in this document points out these are not “regular guidelines” developed after thorough analysis of all the available evidence published since the last update. Instead, they are meant to provide temporary basic management pointers on how to handle different scenarios of cardiac patients in the...
Nominally deployed transcatheter heart valves SAPIEN 3 has shown excellent durability in accelerated testing to an equivalent 25 year-wear. S3 durability resulted comparable to surgical biological valve durability. Non-nominal implants (overexpansion, underexpansion, and elliptical) also showed excellent durability to an equivalent 5 year-wear. The aim of this study was to test nominally deployed S3 durability to 1 billion...
Transcatheter aortic valve replacement (TAVR) seems to be safe in low-risk patients with bicuspid aortic valve stenosis. Their hospital length of stay was very short, with zero mortality, and zero disabling stroke. Subclinical leaflet thrombosis and device durability are still unknown. The United States Food and Drug Administration (FDA) approved TAVR for low-risk patients. However,...
Administrating Recombinant Human C1-Esterase-Inhibitor (rhC1INH) before coronary angiography might mitigate contrast induced kidney injury. In addition, it shows a favorable safety profile in populations with multiple comorbidities. The contrast material used in all our diagnostic tests and therapeutic procedures causes tubular cytotoxicity and ischemia/reperfusion injury. rhC1INH had been effective at mitigating this mechanism in experimental...
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...
