ABSTRACT
Cardiac surgical patients are often discharged to a rehabilitation facility to complete the convalescence in a protected setting. This care pathway is usually reserved for elderly and fragile patients, with severe and invalidating comorbid conditions. Between March and April 2020, nineteen patients were discharged from our unit to a rehabilitation clinic where a hotbed of SARS-CoV-2 infection was documented on April 17. After the outbreak, all patients underwent screening with real-time PCR on nasal swabs, and 18/19 patients were found positive. Diversely from other observations on perioperative COVID-19 reporting mortality rates of 30-40%, the COVID-19 had a benign course in our cohort: six patients were completely asymptomatic, and only seven patients required hospitalization (no deaths). We describe the baseline, operative and postoperative features of these patients, and present some potential explanations for the surprisingly benign course of the COVID-19 in this cohort.
