Abstract

This prospective study was undertaken to analyze the outcomes of conservative surgery with the "clover technique" for active infective tricuspid valve endocarditis. Five consecutive patients underwent surgery for active infective tricuspid valve endocarditis. The mean age was 36.6 years. Four of the patients were men. In all patients, the tricuspid valve had become mutilated and infected. One patient had associated mitral endocarditis, and one had aortic endocarditis. Staphylococcus aureus was the most common bacterial species. Conservative surgery was indicated in all patients with infection limited to the leaflets and/or subvalvular apparatus of the tricuspid valve. Total resection of infected tissues was achieved in all cases. The tricuspid valve was then reconstructed according to the clover technique. A tricuspid annular ring was used in 2 patients. All 5 patients survived surgery. Intraoperative transesophageal and predischarge transthoracic echocardiographic evaluations showed good results in all patients. The mean follow-up time was 26.4 +/- 12.5 months. No recurrent bacterial tricuspid endocarditis occurred during follow-up. All patients were in New York Heart Association functional class I. A transthoracic echocardiog...Continue Reading

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.
