1. 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

2. 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

3. Using a 3D printer in cardiac valve surgery: a systematic review
RESUMO INTRODUÇÃO: A impressora 3D é utilizada como coadjuvante no planejamento de cirurgias de cardiopatias complexas. OBJETIVOS: Analisar o uso e os benefícios da impressão 3D em cirurgias de válvula cardíaca por meio de revisão sistemática da literatura. MÉTODOS: Esta revisão sistemática foi conduzida de acordo com os itens do Preferred Rep

5. Influence of critical atherosclerotic coronary artery disease in hospital mortality of patients with aortic stenosis submitted to aortic valve replacement / Influência da doença aterosclerótica arterial coronária crítica na mortalidade hospitalar de pacientes portadores de estenose aórtica submetidos à substituição valvar
Com o aumento da expectativa de vida nas últimas décadas, tem ocorrido aumento concomitante da prevalência da estenose aórtica degenerativa e da doença aterosclerótica arterial coronária. O presente estudo visa avaliar a influência da doença ateroslerótica arterial coronária crítica na mortalidade hospitalar de pacientes portadores de estenose a�

6. A new surgical approach for treating dilated cardiomyopathy with mitral regurgitation
OBJECTIVE: To evaluate the early outcome of mitral valve prostheses implantation and left ventricular remodeling in 23 patients with end-stage cardiomyopathy and secondary mitral regurgitation (NYHA class III and IV). METHODS: Mitral valvular prosthesis implantation with preservation of papillary muscles and chordae tendinae, and plasty of anteriun cuspid fo

7. Intravalvular Implantation of Mitral Valve Prostheses
We describe a technique of intravalvular implantation of a low-profile prosthesis that has been used in nine patients with mitral valve lesions. This technique preserves the anterior and posterior chordae and papillary mechanisms, which may decrease the incidence of postoperative left ventricular dysfunction that has been noted following standard mitral valv

8. Asymptomatic Strut Fracture in DeBakey-Surgitool Aortic Valves: Incidence, Management, and Metallurgic Aspects
From August 1971 through November 1972, we implanted 62 Model 2 DeBakey-Surgitool aortic valve prostheses in 62 patients, 4 of whom later had clinically asymptomatic strut fractures. In 1 case, the patient died suddenly, and autopsy revealed detachment of the ball-cage; in each of the other 3 cases, fractures of 2 struts close to the base of the prosthesis w

9. Closing sounds and related complaints after heart valve replacement with St Jude Medical, Duromedics Edwards, Björk-Shiley Monostrut, and Carbomedics prostheses.
OBJECTIVE--To measure the noise produced and related subjective complaints after implantation of four different mechanical heart valve prostheses and to identify further factors related to the patient and prosthesis that influence noise generation and complaints. DESIGN--Sound pressure was measured 5 and 10 cm and 1 m from the point of maximal impulse on the
