Aortic valve replacement in patients over 70 years

Scandinavian Journal of Thoracic and Cardiovascular Surgery

Abstract

Twenty-seven patients 70 years of age or more were operated upon with aortic valvular replacement with an early mortality rate of 7%. No more patients died during a mean follow-up period of 28 months. The Björk-Shiley standard tilting disc valve was implanted in 15 cases and the new convexo-concave model in 12 cases. Sixty-seven per cent of the patients had narrow aortic roots (21 and 23 mm prosthesis diameters) compared with 40% of younger patients. Thrombo-embolic complications occurred in 2 patients who had not received anticoagulant treatment. No such complications were recorded in the remaining 23 surviving patients treated with anticoagulants. All the surviving patients (except one who was re-operated because of a thrombotic encapsulation of the disc) were markedly improved postoperatively. High age alone is no longer an absolute contra-indication for aortic valve replacement. The convexo-concave Björk-Shiley tilting disc prosthesis is suitable in these patients because of its low resistance of flow at small diameters. The importance of anticoagulant treatment even in elderly patients is emphasized.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
