Background Heart disease is the leading non-obstetric cause of maternal death during pregnancy. In this field, the emergence of pandemic COVID-19 has caused the worst-case scenario considering that pregnant women are more susceptible to viral infections, and preexisting cardiac disease is the most prevalent co-morbidity among COVID-19 deaths. Purpose To assess the maternal and fetal outcomes of COVID-19 during pregnancy of women with heart diseases. Methods During the year 2020, among 82 pregnant women with heart disease followed consecutively at the Instituto do Coração-InCor, seven of them with an average age of 33.2 years had COVID-19 during their pregnancies. The underlying heart diseases were rheumatic valve disease (5 pt), congenital heart disease (1 pt) and one case with acute myocarditis, without preexisting cardiopathy. The prescription (antibiotics, inotropes, corticosteroids and others) used was according to the clinical conditions required for each patient, however subcutaneous or intravenous heparin was used in all patients. Results Only one case had an uneventful maternal-fetal course, the other six women required hospitalization / ICU for an average of 25.3 days, including the need for mechanical ventilation in two of them. Serious complications were related to respiratory failure (ADRS), recurrent atrial flutter with hemodynamic instability, acute pulmonary edema, and cardiogenic shock associated with sepsis which caused two maternal deaths. There were two emergency mitral valve interventional, percutaneous balloon valvuloplasty and valve bioprosthesis replacement, respectively. There were five premature births with an average gestational age of 34.2 weeks of gestation, which resulted in one stillbirth. Pathological findings of three placental and the six-months follow-up of the babies did not confirm vertical transmission of COVID-19. Conclusions The uncertain evolution given of the overlapping complications of three conditions – COVID-19, pregnancy, and heart disease – implies an increased risk for women with heart diseases of childbearing age, for whom pregnancy should be discouraged and planned after vaccination Funding Acknowledgement Type of funding sources: None.

Background Epidemiological data from the COVID-19 pandemic report that patients with pre-existing cardiovascular disease have worse outcomes and higher mortality, and that pregnant women should be considered at high risk. Case summary A 25-year-old pregnant woman on the waiting list for a heart transplant, with a history of complete atrioventricular canal surgery, mitral mechanical prosthetic implant (St Jude-27), and cardiac resynchronization therapy (Boston Scientific) was hospitalized at 30 weeks of gestation for treatment of heart failure. After 7 days of hospitalization, she had a positive RT–PCR test for severe acute respiratory syndrome coronavirus 2 with progressive worsening of her clinical condition and acute foetal distress. Hence emergency caesarean section was performed. After the birth, the patient required mechanical ventilation, progressing to multiple organ system failures. Conventional inotropic drugs, antibiotics, and mechanical ventilation for 30 days in the intensive care unit provided significant clinical, haemodynamic, and respiratory improvement. However, on the 37th day, she suddenly experienced respiratory failure, gastrointestinal and airway bleeding, culminating in death. Discussion Progressive physiological changes during pregnancy cause cardiovascular complications in women with severe heart disease and higher susceptibility to viral infection and severe pneumonia. COVID-19 is known to incite an intense inflammatory and prothrombotic response with clinical expression of severe acute respiratory syndrome, heart failure, and thromboembolic events. The overlap of these COVID-19 events with those of pregnancy in this woman with underlying heart disease contributed to an unfortunate outcome and maternal death.

OBJECTIVE: We aimed to evaluate whether the inclusion of videothoracoscopy in a pleural empyema treatment algorithm would change the clinical outcome of such patients. METHODS: This study performed quality-improvement research. We conducted a retrospective review of patients who underwent pleural decortication for pleural empyema at our institution from 2002 to 2008. With the old algorithm (January 2002 to September 2005), open decortication was the procedure of choice, and videothoracoscopy was only performed in certain sporadic mid-stage cases. With the new algorithm (October 2005 to December 2008), videothoracoscopy became the first-line treatment option, whereas open decortication was only performed in patients with a thick pleural peel (>2 cm) observed by chest scan. The patients were divided into an old algorithm (n = 93) and new algorithm (n = 113) group and compared. The main outcome variables assessed included treatment failure (pleural space reintervention or death up to 60 days after medical discharge) and the occurrence of complications. RESULTS: Videothoracoscopy and open decortication were performed in 13 and 80 patients from the old algorithm group and in 81 and 32 patients from the new algorithm group, respectively (p
