Transcatheter aortic-valve replacement (TAVR) with the use of a self-expanding prosthesis is superior to medical therapy in patients with severe, symptomatic aortic stenosis in whom surgical aortic-valve replacement has been associated with prohibitive risk. Among patients considered at high risk, TAVR may be an alternative to surgery. The comparative...
Courtesy of Dr. Carlos Fava. Frailty should be taken into account when deciding transcatheter aortic valve implantation (TAVI). Even though several scales of frailty are available, they are yet to be tested in this group, with this strategy. The study analyzed 101 patients, frailty was assessed clinically according to the following tests: Katz index...
Courtesy of Dr. Carlos Fava. Transcatheter aortic valve replacement (TAVR) has shown ample benefit in different groups, but one of its drawbacks continues to be the need for permanent pacemaker (PPM), which ranges between 5 and 30%. Its long term impact in terms of mortality is still controversial, since some studies associate it with...
This work studies cognitive evolution after transcatheter aortic valve implantation (TAVI). Previous smaller studies reported conflicting results on cognitive function after TAVI. This study prospectively included 229 patients who were ≥70 years old, had undergone TAVI and were assessed using the Mini Mental State Examination before and 6 months after the procedure. Cognitive deterioration or improvement was...
This study, presented in Rome at the European Society of Cardiology Congress 2016 and published simultaneously online in the Journal of the American College of Cardiology (JACC), has identified a post-TAVI valve thrombosis rate of 7% using multidetector computerized tomography (CT). However, the vast majority of cases were completely asymptomatic. Previous studies had shown...
Cerebral embolization is a relatively frequent complication during transcatheter aortic valve replacement (TAVR). The hypothesis behind this study is that the incidence of cerebral embolization might be decreased by anticoagulation with bivalirudin, instead of heparin. The first study objective was to determine the proportion of patients with new cerebral embolus after TAVI and...
Courtesy of Dr. Carlos Fava. This study sought to analyze the clinical impact and the level of improvement of mitral regurgitation (MR) in patients who receive a transcatheter aortic valve replacement (TAVR), and to find potential candidates for double valve repair with percutaneous techniques. Of 1.110 patients included, 177 (15.9%) suffered from severe pre-TAVR mitral...
Location: Aloysio de Castro State Cardiology Institute – (IECAC). Operators: Edgard Quintella, Carlos Cardoso and Alexandre Fuks. Chairpersons: Luiz Antonio Ferreira Carvalho and Paulo Caramori. Panelists: Edgard Freitas Quintella, Deborah Christina Nercolini, Antenor Lages Fortes Portela, Luis Ramon Virgen Carrillo and Gustavo Vignolo.
Courtesy of Dr. Carlos Fava. The benefits of transcatheter aortic valve implantation (TAVI) have been widely shown, but there is no evidence on sex-specific outcomes. Some studies have shown lower mortality and better evolution of the ventricular function in women, yet with more bleeding and stroke; however, it remains unclear. This study included 1,019 patients...
Courtesy of Dr. Carlos Fava. Body mass index (BMI) has always played an important role in heart surgery. However, there is little evidence on BMI effects on TAVI. This study included 491 patients, which were divided according to BMI into: low (<20 Kg/m2 ) normal (20-24.9 Kg/m2 ) overweight (25-30 Kg/m2 ) obese...
