Concomitant aortic and mitral valve replacement or concomitant aortic valve replacement and mitral repair can be a challenge for the cardiac surgeon: in particular, because of their structure and design, two bioprosthetic heart valves or an aortic valve prosthesis and a rigid mitral ring can interfere at the level of the mitroaortic junction. Therefore, when a mitral bioprosthesis or a rigid mi...

INTRODUCTION The transcatheter aortic valve implantation in the treatment of high-risk symptomatic aortic stenosis has increased the number of implants every year. The learning curve for transcatheter aortic valve implantation has improved since the last 12 years, allowing access alternatives. OBJECTIVE The aim of this study is to approach the implantation of transcatheter aortic valve throug...

BACKGROUND The safety and effectiveness of the fully repositionable LOTUS valve system as compared with the balloon-expandable Edwards SAPIEN 3 prosthesis for the treatment of aortic stenosis has not been evaluated to date. METHODS AND RESULTS All patients undergoing transcatheter aortic valve implantation with the Edwards SAPIEN 3 or the LOTUS valve system were included into the Swiss Transc...

INTRODUCTION In spite of significant recent advances in imaging modalities for studying cardiac hemodynamics, present day in vivo measurement techniques can only resolve large scale blood flow features. Understanding flow patterns in the heart at physiological conditions and scales sufficiently fine for establishing quantitatively links between disease and patientspecific hemodynamics continues...

A brief account of the history of the development of cardiac valvular prostheses is given. The use of these devices is analyzed. The authors describe the successive stages of the use of the various types of mechanical prosthetic valves with special reference to the experience in Mexico. They refer to the manufacture of testing and clinical results with the Biomed valves made in Mexico. It is co...

BACKGROUND Transcatheter aortic valve implantation (TAVI) has proven to be a valid option for patients with severe aortic stenosis who are at high perioperative risk, particularly in patients with previous cardiac surgery. Several patients with previous mitral valve surgery were reported to have been successfully treated with TAVI. CASE PRESENTATION Two patients, one with mechanical and one w...

DOI: 10.5935/abc.20170118 Introduction From the earliest days of the heart surgery, the valves, when the reparation was not possible, were replaced by prosthetics using cardiopulmonary bypass. The good results of these procedures are well known. In the recent years, minimally invasive alternatives have been developed, aiming to make possible the treatment of individuals under high risk of compl...

BACKGROUND Severe tricuspid valve (TV) dysfunction may lead to surgical TV replacement with a biological valve prosthesis in patients with congenital heart disease. To expand the lifetime of this valve and reduce the number of surgeries, percutaneous TV implantation (PTVI) may be an effective alternative to repeated surgery. We report on our 2-center experience with PTVI. METHODS AND RESULTS ...

recently, there have been more reports of cardiac valve infections due to the increasing number of intravenous (iv) drug abusers and chronic renal failure patients. among cardiac valves, tricuspid valve is most commonly affected in the course of endocarditis. appropriate management of these patients is a challenging and controversial issue in the field of cardiac surgery. treatment options in s...

Many patients with severe aortic stenosis never undergo surgical treatment for various reasons. Apart from the standard risks, some patients face an additional problem: their carrying of a mechanical mitral valve. In these patients, transcatheter aortic valve implantation is a therapeutic option. The literature contains only few reports of this procedure being performed (usually transapically) ...
