Background And Aim Of The Study: With the changing age structure of the population, cardiothoracic surgeons must deal with an increasing number of patients suffering from degenerative valve disease. Septuagenarians with triple valve disease may be refused surgery due to a potentially high perioperative risk related to co-morbidities. The study aim was to elucidate the indications and compare outcome, with a focus on age-related mortality and morbidity.
Methods: Between December 1996 and July 2010, a total of 90 consecutive patients (45 males, 45 females; mean age 68 +/- 9 years; logistic EuroSCORE 21 +/- 16%) underwent triple-valve surgery at Hannover Medical School. Of these patients, 70% had degenerative disease, 19% endocarditis, and 11% a rheumatic cause, while 24% underwent cardiac redo-surgery. For further analysis, the cohort was divided into two groups according to age: < or = 70 years (n=44) and >70 years (n=46). The follow up was performed according to current guidelines for reporting mortality and morbidity after cardiac valve interventions, including a quality of life assessment (Minnesota Living With Heart Failure Questionnaire; MLHFQ).
Results: Mortality among the patients was 16%, 24%, and 26% at 30, 60, and 90 days, respectively. The one-year survival was 69% for the whole cohort, and no difference was seen between the age groups. Follow up (mean 46 months) was complete in 96% of all patients who survived at least three months (n=67). Valve-related morbidity was low in both groups, with predominantly a recurrence of tricuspid insufficiency. The MLHFQ score was similar in both groups.
Conclusion: Triple-valve surgery is associated with a high perioperative risk. However, the acceptance of elderly patients for this surgery is not associated with a higher mortality or valve-related morbidity. The patients' quality of life was acceptable during follow up, and not affected by age. Hence, the refusal of surgery should depend not on old age alone but rather on an individualized assessment of the patient.

Osteogenic differentiation is crucial in normal bone formation and pathological calcification, such as calcific aortic valve disease (CAVD). Understanding the proteomic and transcriptomic landscapes underlying this differentiation can unveil potential therapeutic targets for CAVD. In this study, we employed RNA sequencing transcriptomics and proteomics on a timsTOF Pro platform to explore the multiomics profiles of valve interstitial cells (VICs) and osteoblasts during osteogenic differentiation.

Aortic stenosis is a prevalent disease that is treated with either mechanical or bioprosthetic valve replacement devices. However, these implants can experience problems with either functionality in the case of mechanical valves or long-term durability in the case of bioprosthetic valves. To enhance next generation prosthetic valves, such as biomimetic polymeric valves, an improved understanding of the native aortic valve leaflet structure and mechanical response is required to provide much needed benchmarks for future device development.

Article Synopsis
- The study focuses on the outcomes of aortic valve replacement (AVR) in young Moroccan patients with severe aortic regurgitation and impaired left ventricle function.
- A total of 42 out of 110 patients with significant aortic regurgitation and an ejection fraction of ≤35% underwent AVR, showing a low immediate postoperative mortality rate of 4.7%.
- Long-term follow-up indicated a high survival rate of 86.8% after 15 years, along with significant clinical improvements and increased left ventricle ejection fraction post-surgery.
