Background We sought to assess the impact and predictors of Coronavirus Disease 2019 (COVID‐19) infection and severity in a cohort of congenital heart disease (CHD) patients at a large CHD center in New York City. Methods and Results We performed a retrospective review of all individuals with CHD followed at Columbia University Irving Medical Center who were diagnosed with COVID‐19 between 3/1/2020 and 7/1/2020. The primary endpoint was moderate/severe response to COVID‐19 infection defined as a) death during COVID‐19 infection; or 2) need for hospitalization and/or respiratory support secondary to COVID‐19 infection. Among 53 COVID‐19 positive patients with CHD, 10 (19%) were <18 years old (median age 34 years). 31 (58%) had complex congenital anatomy including 10 (19%) with a Fontan repair. Eight (15%) had a genetic syndrome, six (11%) had pulmonary hypertension (PH), and nine (17%) were obese. Among adults, 18 (41%) were physiologic class C or D. For the entire cohort, nine (17%) had a moderate/severe infection, including three deaths (6%). After correcting for multiple comparisons, the presence of a genetic syndrome (OR=35.82: p=0.0002), and in adults, physiological Stage C or D (OR=19.38: p=0.002) were significantly associated with moderate/severe infection. Conclusions At our CHD center, the number of symptomatic COVID‐19 patients was relatively low. CHD patients with a genetic syndrome and adults at advanced physiological stage were at highest risk for moderate/severe infection.

Older patients should not be excluded from PFO closure. The procedure seems as safe and effective in preventing recurrent stroke in the older, as in the younger population. Older patients seem more prone to developing AF.
