OBJECTIVES: A transcatheter heart valve technique can be used in failed mitral valve repairs with annuloplasty rings, deterioriated bioprostheses and in mitral annular calcification, all serving as 'docking stations' for balloon-expandable valves. Specially designed transcatheter mitral valve platforms are used in ongoing studies for native mitral valve regurgitation. We present our single centre experience with transcatheter mitral valve implantation-transapical approach procedures in eleven patients...

Mechanical valves used for aortic valve replacement (AVR) continue to be associated with bleeding risks because of anticoagulation therapy, while bioprosthetic valves are at risk of structural valve deterioration requiring reoperation. This risk/benefit ratio of mechanical and bioprosthetic valves has led American and European guidelines on valvular heart disease to be consistent in recommending the use of mechanical prostheses in patients younger than 60 years of age. Despite these recommendations, the use of bioprosthetic valves has significantly increased over the last decades in all age groups...

INTRODUCTION: Cross-linking and anti-calcification of prosthetic heart valves have been continuously improved to prevent degeneration and calcification. However, non-calcific structural deteriorations such as cuspal dehiscences along the stent still require further analysis. MATERIAL AND METHOD: Based upon the previous analysis of an explanted valve after 7 years, a fresh commercial aortic valve was embedded in poly(methyl methacrylate) (PMMA) and cut into slices to ensure the detailed observation of the assembly and material structures...

An 84-year-old man with symptomatic severe aortic stenosis received transcatheter aortic valve implantation (TAVI). Dual-antiplatelet therapy was continued for 6 months post TAVI, and aspirin alone was used thereafter. Four-dimensional multidetector computed tomography revealed a new hypoattenuated leaflet thickening (HALT) with reduced leaflet motion at 1 year, considered to indicate leaflet thrombosis. At the 2-year follow-up, leaflet mobility had improved, with spontaneous regression of HALT. This is the first report of confirmed spontaneous regression of possible transcatheter heart valve thrombosis and recovery of leaflet mobility without the need for additional anticoagulant...

BACKGROUND: The implantation of rotary blood pumps as ventricular assist devices (VADs) has become a viable therapy for quite a number of patients with end-stage heart failure. However, these rotary blood pumps cause adverse events that are related to blood trauma. It is currently believed that turbulence in the pump flow plays a significant role. But turbulence has not been measured to date because there is no optical access to the flow space in rotary blood pumps because of their opaque casings...

Cardiac catheterization has greatly contributed to the progress made in the management of congenital heart diseases (CHD). Initially used in diagnosis, it allowed the understanding of heart diseases, their anatomy and hemodynamics. Gradually, the development of interventional cardiology has played a major role in the management of these malformations (Patent ductus arteriosus [PDA] and atrial septal defect [ASD] closure, pulmonary dilatation, percutaneous pulmonary valve implantation…). The development of such technology was made possible through the concomitant development of imaging techniques: fluoroscopy, ultrasound, MRI and CT...

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term "cardiac surgery". Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal...

BACKGROUND: Patients with tetralogy of Fallot (TOF) have increased risk of atrial arrhythmias. HYPOTHESIS: A measure of atrial dispersion, the P-wave vector magnitude (Pvm), can identify patients at risk for perioperative atrial flutter (AFL) or intra-atrial re-entrant tachycardia (IART) in a large TOF cohort. METHODS: We performed a blinded, retrospective analysis of 158 TOF patients undergoing pulmonary valve replacement between 1997 and 2015...

The optimal antithrombotic therapies for transcatheter aortic valve implantation (TAVI) and MitraClip implantation have not been well established. We conducted a narrative review from currently available studies between January 2002 and May 2016 to highlight the advantages and disadvantages of antithrombotic therapy use in cardiac catheter-based therapeutic techniques. Recently, these techniques have dramatically altered the approach towards valvular heart diseases management. The introduction into clinical practice, of TAVI for severe aortic stenosis and MitraClip for mitral regurgitation, has revolutionized interventional cardiology...
