Few aortic dissection survivors receive long-term imaging surveillance

(HealthDay)—Only one in seven people who survive acute type A aortic dissection (ATAAD) receive recommended surveillance imaging, according to a study published in the Nov. 9 issue of the Journal of the American College of Cardiology.

Kevin R. An, M.D., buy brand viagra quebec overnight shipping from the University of Toronto, and colleagues sought to define the real-world frequency of postoperative imaging and characterize long-term outcomes of ATAAD. Analysis included 888 patients who survived urgent ATAAD repair between April 1, 2005, and March 31, 2018.

The researchers found that over a median follow-up of 5.2 years, 14 percent of patients received guideline-directed imaging surveillance (GDIS) throughout follow-up. At one year, the mortality rate was 4 percent, compared to 14 percent at five years and 29 percent at 10 years. At one year, the incidence of aortic reintervention was 3 percent, compared to 9 percent at five years and 17 percent at 10 years. The majority of reinterventions were urgent (68 percent), and they carried a 30-day mortality rate of 9 percent. Greater adherence to GDIS was associated with mortality (hazard ratio, 1.08) and reintervention (hazard ratio, 1.04).
