Clinical Profile and 30-Day Outcomes of Patients with Bicuspid Aortic Valve Undergoing Aortic Valve and/or Aorta Surgery. / Perfil Clínico e Desfechos em 30 Dias de Pacientes Portadores de Valva Aórtica Bicúspide Submetidos à Cirurgia em Valva Aórtica e/ou Aorta.

BACKGROUND: The bicuspid aortic valve (BAV) affects 0.5 to 2% of the population and is associated with valve and aortic alterations. There is a lack of studies on the profile of these patients in the Brazilian population. OBJECTIVE: To describe the profile of patients with BAV undergoing valve and/or aortic surgery in a tertiary cardiology center, in addition to the outcomes related to the intervention. METHODS: Retrospective cohort including 195 patients (mean age 54±14 years, 73.8% male) diagnosed with BAV who underwent surgical approach (valvular and/or aorta) from 2014 to 2019. Clinical data, echocardiographic and tomographic studies were evaluated, as well as characteristics of the intervention and events in 30 days. A value of p<0.05 was considered statistically significant. RESULTS: We found a high prevalence of aortic aneurysm (56.5%), with a mean diameter of 46.9±10.2 mm. Major aortic regurgitation was found in 25.1% and major aortic stenosis in 54.9%. Isolated aortic valve surgery was performed in 48.2%, isolated aortic surgery in 6.7% and combined surgery in 45.1%. The 30-day mortality was 8.2%. In the multivariate analysis, the predictors of the combined outcome at 30 days (death, atrial fibrillation and reoperation) were age (OR 1.044, 95% CI 1.009-1.081, p=0.014) and left ventricular mass index (OR 1.009, 95% CI 1.000-1.018, p=0.044). CONCLUSION: Patients with BAV approached in our service have a higher incidence of aortopathy, with the additional need to evaluate the aorta with computed tomography or magnetic resonance imaging.

FUNDAMENTO: A válvula aórtica bicúspide (VAB) atinge de 0,5 a 2% da população e está associada a alterações valvares e de aorta. Há carência de estudos sobre o perfil desses pacientes na população brasileira. OBJETIVO: Descrever o perfil de pacientes com VAB submetidos à cirurgia valvar e/ou de aorta em um centro cardiológico terciário, assim como os desfechos relacionados à intervenção. MÉTODOS: Coorte retrospectiva incluindo 195 pacientes (idade média 54±14 anos, 73,8% do sexo masculino) com diagnóstico de VAB submetidos à abordagem cirúrgica (valvar e/ou de aorta) no período de 2014 a 2019. Foram avaliados dados clínicos, ecocardiográficos e tomográficos, além das características da intervenção e eventos em 30 dias. O valor de p<0,05 foi considerado estatisticamente significante. RESULTADOS: Encontramos alta prevalência de aneurisma de aorta (56,5%), com diâmetro médio de 46,9±10,2 mm. Insuficiência aórtica importante foi encontrada em 25,1% e estenose aórtica importante em 54,9%. Cirurgia isolada em valva aórtica foi realizada em 48,2%, cirurgia isolada de aorta em 6,7% e cirurgia combinada em 45,1%. A mortalidade em 30 dias foi de 8,2%. Na análise multivariada, os fatores preditores de desfecho combinado em 30 dias (morte, fibrilação atrial e reoperação) foram idade (OR 1,044, IC 95% 1,009-1,081, p=0,014) e o índice de massa do ventrículo esquerdo (OR 1,009, IC 95% 1,000-1,018, p=0,044). CONCLUSÃO: Pacientes com VAB abordados no nosso serviço apresentam uma maior incidência de aortopatia, com a necessidade adicional de avaliação da aorta com tomografia computadorizada ou ressonância magnética.

COVID-19, congenital heart disease, and pregnancy: dramatic conjunction-case report.

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.

Characteristics of training and motivation of physicians working in emergency medicine.

INTRODUCTION:: Emergency medicine is an area in which correct decisions often need to be made fast, thus requiring a well-prepared medical team. There is little information regarding the profile of physicians working at emergency departments in Brazil. OBJECTIVE:: To describe general characteristics of training and motivation of physicians working in the emergency departments of medium and large hospitals in Salvador, Brazil. METHOD:: A cross-sectional study with standardized interviews applied to physicians who work in emergency units in 25 medium and large hospitals in Salvador. At least 75% of the professionals at each hospital were interviewed. One hospital refused to participate in the study. RESULTS:: A total of 659 physicians were interviewed, with a median age of 34 years (interquartile interval: 29-44 years), 329 (49.9%) were female and 96 (14.6%) were medical residents working at off hours. The percentage of physicians who had been trained with Basic Life Support, Advanced Cardiovascular Life Support and Advanced Trauma Life Support courses was 5.2, 18.4 and 11.0%, respectively, with a greater frequency of Advanced Cardiovascular Life Support training among younger individuals (23.6% versus 13.9%; p<0.001). Thirteen percent said they were completely satisfied with the activity, while 81.3% expressed a desire to stop working in emergency units in the next 15 years, mentioning stress levels as the main reason. CONCLUSION:: The physicians interviewed had taken few emergency immersion courses. A low motivational level was registered in physicians who work in the emergency departments of medium and large hospitals in Salvador.
