Aortic valve replacement in patients with poor ventricular function-early and late results with long-term follow-up

The Japanese Journal of Surgery

Abstract

A series of 62 consecutive patients with an ejection fraction of 0.4 or less (mean 0.28 with a range from 0.10 to 0.40; 22 between 0.10 and 0.20, 18 between 0.21 and 0.30, and 22 between 0.31 and 0.40) who underwent aortic valve replacement from January 18, 1972 to December 20, 1976 was reviewed. Preoperatively two patients were in Class II, 35 in Class III and 25 in Class IV of the New York Heart Association functional classification (N.Y.H.A.). Thirty-nine patients (Group 1) underwent isolated aortic valve replacement and 23 patients (Group 2) underwent aortic valve replacement with associated procedures including aortocoronary bypass in 15. The operative mortality was 8 percent in Group 1, 17 percent in Group 2, and 11 percent overall. In the group of 15 patients with coronary artery disease, the operative mortality of aortic valve replacement and aorto-coronary bypass was 27 percent. Since January 1974, isolated aortic valve replacement was performed with no operative deaths in 25 consecutive patients in Group 1 including 10 patients with an ejection fraction of 0.2 or less. Five-year survival rates were 70 percent in Group 1, 64 percent in Group 2 and 68 percent overall. In the 38 currently living patients, 32 showed clini...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.
