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…
Myocardial Fibrosis in Severe Aortic Stenosis: A Matter of Sex?
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…
Procedural Rescheduling Criteria in the Pandemic Era
Patients with structural heart disease are at higher risk in the face of the new coronavirus infection due to both advanced age and numerous comorbidities. All variables must be taken into account when deciding whether a patient can wait (so as to minimize the risk of exposure to the virus) or their pathology must be…
Virtual ACC 2020 | First Results of Evolut in Low-Risk Bicuspid Valves
The initial results of this study presented “virtually” at the American College of Cardiology (ACC) 2020 Scientific Session suggest that patients with severe bicuspid aortic stenosis can be treated with self-expandable valve Evolut. This is a small study presenting its 30-day outcomes. There is still a long way to go. The rate of all-cause mortality…
Pre-TAVR Revascularization: Angiographic or Physiological?
In patients undergoing transcatheter aortic valve replacement (TAVR), fractional flow reserve (FFR) guided revascularization is associated with favorable results compared against the traditional angiography guided revascularization. Given the complete lack of randomized studies, this observational study is the best we have to decide how to guide revascularization in patients with symptomatic severe aortic stenosis undergoing…
AHA 2019 | Sapien vs Evolut: A Head-to-Head Study Seems Mandatory
Two French registries have carried out a propensity matched comparison which suggest differences between balloon-expandable valves (BEV) and self-expandable valves (SEV) in hard end points such as mortality. The only FDA approved commercially available transcatheter heart valves in the US are the BE Sapien 3 (Edwards Lifesciences) and the SE CoreValve Evolut PRO (Medtronic). Both…
Negative Impact of Pulmonary Hypertension in TAVR
Courtesy of Dr. Carlos Fava. The presence of pulmonary hypertension (PH) is frequent in severe aortic stenosis. This can be classified in: isolated pre-capillary PH, isolated post-capillary PH, and combined post-capillary and pre-capillary PH. At present, little research has looked into the disease from this perspective. The study looked at 1400 patients and divided them…
Meta-Analysis of Large TAVR Studies on Low-Risk: Evidence is Consistent
This meta-analysis which included the 4 large randomized studies on transcatheter aortic valve replacement (TAVR) vs surgical aortic valve replacement (SAVR) in low-risk patients recently published in JACC, showed TAVR is associated with significant lower mortality compared against SAVR at one year follow up. These results add to the mounting evidence showing that when it…
Loss in Life Expectancy after Surgical Aortic Valve Replacement
This study found after surgical aortic valve replacement (SAVR) patients had shorter life expectancy, compared against the general population. This loss in life expectancy was significant, especially in young patients. These results provide essential information to advice patients before and after SAVR. This is an observational national cohort study to assess long term relative survival…
Clinical Implications of the New Hypertension Guidelines
Hypertension is the first modifiable risk factor affecting morbidity and mortality in nearly half of the adults in the US. The new ACC/AHA guidelines have issued new standards for the detection assessment and management of high blood pressure. The major change compared against their prior version was stage 1 hypertension definition, defined as systolic blood…
