Preservation of three-dimensional annular movement with the SJM-Seguin mitral annuloplasty ring

Abstract

In order to achieve optimal annuloplasty during mitral valve repair, we developed a new device, the SJM-Seguin annuloplasty ring, with the aim of remodeling, correcting dilatation, and preserving physiologic annulus function. This ring has variable flexibility; that is, it is sufficiently rigid in its anterior region to maintain intercommissural distance, yet sufficiently flexible in its posterior region so as not to interfere with left ventricular function and to permit the natural three-dimensional annular mobility. Following successful studies in animals, 75 patients were operated on for mitral regurgitation between January 1994 and May 1996. The patients' mean age was 60.4 +/- 13.2 years; 53.8% were men. The cause of mitral insufficiency was degenerative in 77.4% of patients, rheumatic in 12%, ischemic in 5.3%, and infectious in 5.3%. Associated procedures were carried out in 36% of the cases. There were no intraoperative deaths, but two in-hospital deaths and one late death, all of which were unrelated to the annuloplasty ring. Mitral regurgitation, monitored by transesophageal echocardiography decreased from +3.42 +/- 0.6 before repair to +0.31 +/- 0.12 after repair (p < 0.005). Follow up was 100% at a mean of 14.2 months...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.
