Background: Studies reporting on the outcome of 90-year-old patients undergoing cardiac surgery are scant in literature; and currently, those regarding the implementation of trans-catheter techniques number even fewer.

Methods: We compared patients aged >89 years operated on between 1998 and 2008 at 8 Italian cardiac surgery centers, with patients of the same age operated on between 2009 and 2021. All of the patients were operated on with "open" surgery, with the exclusion of percutaneous valve repair/implantation procedures.

Background: Recent data suggested that transcatheter aortic valve replacement (TAVR) may be indicated also for low-risk patients. However, robust evidence is still lacking, particularly regarding valve performance at follow-up that confers a limitation to its use in young patients. Moreover, a literature gap exists in terms of 'real-world' data analysis.

The operative mortality associated with repeat heart valve surgery is supposedly higher than the mortality associated with the primary operation. However, controversy still surrounds the risk factors and optimal surgical approach for patients requiring repeat cardiac surgery, particularly for those requiring aortic valve replacements (AVR). While the standard approach generally utilizes full sternotomy and peripheral cannulation, alternative approaches such as minimally invasive sternotomy may play an increasingly important role in this field.

Background: Long-chain polyunsaturated omega-3 fatty acids (n-3 PUFA) demonstrated antiarrhythmic potential in experimental studies. In a large multinational randomized trial (OPERA), perioperative fish oil supplementation did not reduce the risk of postoperative atrial fibrillation (PoAF) in cardiac surgery patients. However, whether presupplementation habitual plasma phospholipid n-3 PUFA, or achieved or change in n-3 PUFA level postsupplementation are associated with lower risk of PoAF is unknown.

Objective: Minimally invasive epicardial ablation via right minithoracotomy is an emerging option for patients with drug-refractory nonvalvular atrial fibrillation. To guide the development of rational treatment algorithms, factors predisposing to recurrence of arrhythmia need to be quantified and eventually treated. We addressed the association of the plasma levels of homocysteine and the recurrence of atrial fibrillation after minimally invasive ablation.

We address the calculation of charge carrier mobility of liquid-crystalline columnar semiconductors, a very promising class of materials in the field of organic electronics. We employ a simple coarse-grained theoretical approach and study in particular the temperature dependence of the mobility of the well-known triphenylene family of compounds, combining a molecular-level simulation for reproducing the structural changes and the Miller-Abrahams model for the evaluation of the transfer rates within the hopping regime. The effects of electric field, positional and energetic disorder are also considered.

Objective: The number of older patients being referred for aortic valve replacement with or without combined coronary bypass grafting (CABG) is increasing. The aim of this study was to evaluate operative risk factors, early and long-term results of isolated aortic valve and aortic valve replacement combined with CABG in octogenarians and nonagenarians.

Methods: In the last 10 years, 285 very elderly patients who underwent aortic valve replacement either alone or in combination with coronary artery bypass grafts were retrospectively studied.

We evaluated the effectiveness of a new oxygenator-integrated device for removing lipid particles and leukocytes from shed mediastinal blood in 20 patients undergoing elective cardiac surgery under cardiopulmonary bypass. Another 20 patients undergoing cardiac surgery without the device served as controls. After filtration with the RemoveLL device, lipid particles, leukocytes, and fats were significantly reduced compared to preoperative levels.

Background: Age >90 years represents in many centers an absolute contraindication to cardiac surgery. Nonagenarians are a rapidly growing subset of the population posing an expanding clinical problem. To provide helpful information in regard to this complex decision, we analyzed the operative and 5-year results of coronary and valvular surgical procedures in these patients.

The Bentall-DeBono operation is the technique of choice for aortic root replacement. As more patients do not accept or have contraindications to lifelong anticoagulation, the biological Bentall operation is a good option for these patients, even though complex reoperations would then be required for bioprosthesis degeneration. We studied a modified technique to simplify the reoperations in patients undergoing biological Bentall procedure.
