Background: With improved life expectancy more octogenarians now present with aortic valve disease. Cardiac surgery in this group of patients has previously been considered high risk due to co-morbidities and challenges of rehabilitation. This study seeks to challenge the concept of octogenarian cardiac surgery "unsuitability" by analysing operative outcomes and long term survival following aortic valve replacement.
Methods: Eighty-seven consecutive patients undergoing aortic valve replacement between 2000 and 2009 at St Vincent's Hospital were retrospectively identified. Statistical analysis was performed using SPSS (version 15 and 19).
Results: The average age was 82.7 ± 2.4 years. The mean logistic EuroSCORE was 18.86 ± 14.11. Post-operatively, four patients required insertion of a permanent pacemaker (4.6%) and five patients had a myocardial infarction (5.8%). In-hospital mortality was 3.4%. Follow-up was 93.1% complete. One-year survival was 92.9%, three-year survival was 86.7% and five-year survival was 75.0%. At follow-up 98.1% of patients were New York Heart Association (NYHA) Class I or II.
Conclusions: Results were excellent despite reasonable co-morbidities and Euroscore risk. Survival was impressive and the NYHA class reflected the success of the surgery in relieving the pathological aortic valve process. Patient age should not be the primary exclusion for cardiac surgery for aortic valve disease.

Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.

Background: Transcatheter aortic valve replacement (TAVR) is a well-established treatment option for patients with severe aortic valve stenosis; however, clinical valve thrombosis is a major challenge.
Case Summary: A 92-year-old woman underwent TAVR for severe aortic stenosis. One month later, the patient developed acute heart failure.

We report a 75-year-old female with a history of two heart operations: aortic valve replacement (St. Jude Medical 21 mm) at the age of 44 years for severe rheumatic aortic stenosis and mitral valve replacement (Carbomedics 29 mm) at the age of 51 years for rheumatic mitral regurgitation. Decades later, she presented with exertional dyspnea.

Introduction The study aimed to retrospectively evaluate the early patient outcome and left ventricular function after mitral valve replacement with a tilting disc valve and total preservation. Patients and methods This retrospective observational study includes patients who underwent mitral valve replacement using a tilting disc valve with total preservation of mitral valvular and subvalvular apparatus from July 2021 to August 2022 at a single center. Results The data were reviewed retrospectively for age, sex, comorbidities, operating time, aortic cross-clamp time, cardiopulmonary bypass time, preoperative and postoperative left ventricular ejection fraction, mean gradient across the mitral valve, left ventricular diameter, left atrial size, atrial fibrillation, complications, mortality, and early patient outcome.
