1. Multiple Anterior Mitral Valve Perforation After Deep Transfemoral Aortic Valve Implantation
Abstract Transcatheter aortic valve implantation (TAVI) is an alternative for high-risk aortic valve replacement. There are limited data related to the late complications of TAVI. Deep aortic prosthetic valve implantation can cause direct erosive perforation of anterior mitral leaflet or erosive endothelial lesion which predisposes the tissue to infective en

2. Evaluation of Ventricular Remodeling and Prognosis in Patients with Aortic Stenosis Who Underwent Surgical or Percutaneous Transcatheter Aortic Valve Replacement
ABSTRACT Introduction: Aortic stenosis is the most common heart valve disease in the world, and patients that present with symptoms have a high mortality rate. Aortic valve replacement has the objective of promote left ventricular remodeling, reduce symptoms, and increase overall survival. The objective of this study is to evaluate reverse remodeling of the

3. Ring Fracture of Brazilian Aortic Valve Bioprostheses Using Non-Compliant High-Pressure Transcatheter Balloon, an Ex Vivo Test
ABSTRACT Introduction: Aortic valve bioprostheses ring fracture in valve-in-valve procedures has shown low complication rates and presents as an option in the treatment of patients at high risk for conventional surgery, avoiding high transvalvular gradients, which are associated with increased mortality. Some prostheses available in the market cannot be fra

4. Aortic Valve Repair as a Subspecialty: Still an Institutional Practice or Open for All?
ABSTRACT Aortic valve repair combined with root stabilization procedures have been reported to have reliable mid to long-term outcomes, and this is one of the reasons that various surgical units are accepting these techniques as an option in selected cases. Aortic valve replacement is a standard procedure with established results, but to master its technique

5. Outcomes of Aortic Valve Replacement Via Right Anterior Minithoracotomy and Central Cannulation Versus Conventional Aortic Valve Replacement in Obese Patients
ABSTRACT Introduction: The minimally invasive implantation of aortic valve prosthesis via thoracotomy has numerous advantages and is comfortable, especially during the early postoperative period. Disadvantages of this method include peripheral vessel complications and groin infections. Central cannulation (direct aortic cannulation with superior vena cava c

6. Transcatheter Aortic Valve Implantation in Bicuspid Aortic Valve with Aortic Stenosis: a Meta-Analysis and Trial Sequential Analysis
Abstract Objectives: Bicuspid aortic valve (BAV) is an important aetiology of aortic stenosis and the use of transcatheter aortic valve implantation (TAVI) has not been fully explored in this cohort. This systematic review and meta-analysis compared the outcomes of TAVI in stenotic BAV against tricuspid aortic valve (TAV). Methods: An electronic literature

7. Aortic Valve Reconstruction with Ozaki Technique
Abstract Modern bioprostheses offer a complete and definitive solution to elderly patients who need aortic valve surgery. Nonetheless, the scenario is more demanding when dealing with younger and less fragile patients. In this setting, any prosthetic aortic valve replacement can provide only a suboptimal solution and its related issues have not been fixed ye

9. Rare Presentation of Sinus of Valsalva Aneurysm Treated by Aortic Valve Reimplantation Technique
Abstract Sinus of Valsalva aneurysm is a rare cardiac abnormality which can be acquired or of congenital origin. A spontaneous rupture into the right atrium is possible and, if not adequately treated, may result in a progressive heart failure due to the left-to-right intracardiac shunt. If ruptured sinus of Valsalva aneurysm is diagnosed, surgical repair is

10. Bioprosthetic Aortic Valve Degeneration: a Review from a Basic Science Perspective
Abstract Introduction: The increase in the prevalence of aortic stenosis due to an aging population has led to an increasing number of surgical aortic valve replacements. Over the past 20 years, there has been a major shift in preference from mechanical to bioprosthetic valves. However, despite efforts, there is still no "ideal" bioprosthesis. It is crucial

11. Comparison of Postoperative Outcomes of Sutureless versus Stented Bioprosthetic Aortic Valve Replacement
Abstract Objective: Sutureless aortic valve replacement (Su-AVR) offers an alternative to supra-annular stented biological aortic prostheses. This single-center study aimed to compare early outcomes after aortic valve replacement with sutureless and conventional stented bioprostheses. Methods: In this retrospective study, we analyzed 52 patients who underw

12. High Residual Gradient Following a Self-Expandable Transcatheter Aortic Valve-in-Valve Implantation — Risk Factor Analysis, Outcomes, and Survival
Abstract Introduction: Transcatheter aortic valve-in-valve implantation (TAVI-ViV) can be associated with unfavorable hemodynamic outcomes. This study aimed to estimate the prevalence, identify the risk factors, and evaluate the outcomes and survival of patients with high residual gradients after TAVI-ViV. Methods: A total of 85 patients were included in t
