To the Editor,
We welcome and read with great interest the article “Worse Hospital Outcomes for Children and Adults with COVID‑19 and Congenital Heart Disease” by Strah et al. [1]. The authors retrospectively analyzed (April 2020–March 2021) 160 children with congenital heart disease (CHD) hospitalized with COVID-19, who accounted for 1.7% of the total admissions for COVID-19 in the Vizient Clinical Data Base and compared with other children with COVID-19 without CHD. In addition to being younger, children with COVID-19 had longer lengths of hospital stay, more complications, high mortality, and higher costs.
The authors state, “to the best of our knowledge, ours is the first national study to demonstrate worse outcomes for children and adults with moderate to severe CHD who are hospitalized for COVID-19.” We would like to add that high mortality related to COVID-19 and CHD patients has already been brought to attention.
We have published a multicenter study in Brazil, one of the epicenters of the COVID-19 pandemic [2]. Our survey study which included 46 centers in 22 Brazilian states found that, in addition to the effects broadly reported in the literature [3], such as reduced surgical volume and unbalanced case-mix, there was an increase in mortality among CHD patients infected after repair in the same hospitalization (45.8%). The aforementioned mortality was not related to CHD risk scores, but mainly to COVID-19 presentation. In Strah et al. study, the mortality rate in CHD patients is almost four times higher than in non-CHD patients (3.8%; 0.8%). On the other hand, our findings suggest that postoperative period may play an additional role.
