Significant drop seen in type A aortic dissection after COVID-19

(HealthDay)—A significant decline was seen in the monthly surgical case volume of acute type A aortic dissection in New York City after COVID-19, according to a research letter published online May 14 in the Journal of the American College of Cardiology.

Ismail El-Hamamsy, M.D., Ph.D., from the Icahn School of Medicine at Mount Sinai in New York City, and colleagues examined the impact of the COVID-19 pandemic on the incidence of acute type A aortic dissections using data from 11 hospitals/health systems providing cardiac surgery in New York City. All cases of surgical repair of acute type A aortic dissections were captured from Jan. 1, 2018, to April 15, 2020.

The researchers identified a significant and precipitous 76.5 percent drop in the monthly surgical case volume of acute type A aortic dissection, from 12.8 ± 4.6 cases/month before COVID-19 to 3.0 ± 1.0 cases/month after COVID-19. Low volumes were observed in March and April 2020, confirming the observation. The unusually low volumes after COVID-19 were confirmed in an analysis of the volumes in January to April of the last three years.
