Objectives: The Carpentier-Edwards Perimount Magna Ease (Edwards Lifesciences) pericardial bioprosthesis has demonstrated satisfying hemodynamics at midterm follow-up, but its durability remains unclear. We report our 10-year experience with this third-generation valve implanted in the aortic position, with particular attention to structural valve deterioration.
Methods: From 2007 to 2016 at our center, 338 patients underwent aortic valve replacement using the Perimount Magna Ease pericardial bioprosthesis. Patients were prospectively followed (mean 6.6 ± 2.6 years) with clinical evaluation and yearly echocardiography. Follow-up was 98% complete (7 patients lost) for a total of 2238 valve-years. Bioprosthesis structural valve deterioration was determined by strict echocardiographic assessment based on the Valve Academic Research Consortium 3 criteria.
Results: Overall operative mortality was 1.2%. Actuarial survival including early deaths averaged 80.9% ± 2.2% and 66.7% ± 4.4% after 5 and 10 years of follow-up, respectively. Actuarial freedom from explantation due to structural valve deterioration at 5 and 10 years was 99.6% ± 0.4% and 88.8% ± 5.0%, respectively, and actuarial freedom of structural valve deterioration at 5 and 10 years was 98.5% ± 0.7% and 44.0% ± 6.4%, respectively. More precisely, actuarial freedom of structural valve deterioration stage 3 was 99.6% ± 0.4% at 5 years and 88.3% ± 5.0% at 10 years, whereas freedom of structural valve deterioration stage 2/3 was 98.5% ± 0.7% and 60.9% ± 7.0%, respectively.
Conclusions: With a low rate of explantation due to structural valve deterioration events at 10 years, and particularly a low rate of moderate or severe structural valve deterioration based on echocardiographic Valve Academic Research Consortium 3 criteria, the Carpentier-Edwards Perimount Magna Ease pericardial bioprosthesis remains a reliable choice for a tissue valve in the aortic position.

Aim: There are limited data on the prevalence of calcific aortic valve disease (CAVD) in Māori and known inequities in outcomes after aortic valve intervention. Our study aimed to investigate the prevalence of CAVD in Māori.
Methods: Data from initial clinically indicated echocardiograms performed between 2010 to 2018 in patients aged ≥18 years were linked to nationally collected outcome data.
Background: In developing countries, rheumatic mitral valve stenosis (MS) is still a problem and its progression leads to left atrial (LA) damage. Due to the complexity of the LA geometry, currently used techniques like antero-posterior dimension (LAD) and 2D echo derived LA volume (LAV) have several limitations that are corrected by 3D derived LA volumes in addition to functional evaluation.
Purpose: To assess the LA functions using 2D speckle tracking echocardiography and 3D transthoracic echocardiography in patients with clinically significant MS in comparison to normal healthy subjects.

Aortic stenosis (AS) was historically considered a disease of the left side of the heart, with the main pathophysiological impact being predominantly on the left ventricle (LV). However, progressive pressure overload in AS can initiate a cascade of extra-valvular myocardial remodeling that could also precipitate maladaptive alterations in the structure and function of the right ventricle (RV). The haemodynamic and clinical importance of these changes in patients with AS have been largely underappreciated in the past.

To evade legal controls, new psychoactive substances (NPS), which have been designed as substitutes for traditional and synthetic drugs, are gradually dominating the drug market. Synthetic cannabinoids (SCs), which account for the majority of NPS, are rapidly being derivatized; consequently, controlling increasing abuse by merely listing individual compounds is difficult. Therefore, China has included the entire SC category of SCs listed as legal controlled substances since July 1, 2021.
