Abstract

Aortic root replacement (ARR) after aortic valve replacement (AVR) or ARR is often a major challenge. We performed 12 cases (7 men and 5 women) of ARR as redo operation from July 2002 to June 2009 in our institution. There was no mortality. Among them. ARR was performed in 5 cases, and AVR in 6 cases, at the previous operation. The age at the redo operation was 59.6 +/- 12.7 years. The mean interval between the previous and the redo operations was 6.8 years. In the cases of previous AVR, enlargement of the aortic root or the Valsalva sinus was recognized in 3, artificial valve failure with pannus formation below the valve was in 2, and perivalvular and regurgitation with infection was in 1. In the cases of previous ARR, surgical site infection was seen in 4, among which pseudoaneurysm formation or bleeding from the suture line at the aortic root was the reason for the redo operation in 3 cases. Pseudoaneurysm formation and artificial valve failure may be involved in some type of infection. ARR may be necessary in patients with aortitis.

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.

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.
