We report the case of a 16-year-old pregnant patient with severe aortic stenosis and pulmonary congestion clinically uncontrolled, in whom percutaneous balloon aortic valvuloplasty was used as the first choice of treatment in an emergency procedure. The clinical findings, pathophysiology, diagnostic features, and indications for percutaneous treatment are reported. ⋯ Bicuspid aortic valve occurs in 3% to 6% of patients with congenital heart disease; when associated with commissural fusion, significant stenosis may be present in childhood. The association of severe congenital aortic stenosis and pregnancy is difficult to control clinically, carrying a high risk of maternal and fetal mortality, mainly when manifested with symptoms of pulmonary congestion 1,2.

Intrauterine ductus arteriosus constriction: analysis of a historic cohort of 20 cases.
To describe the relative incidence, presentation, and evolvement of fetuses with early ductus constriction. ⋯ The high incidence of idiopathic constriction of the ductus arteriosus suggests that its diagnosis is underestimated and that many cases of persistence of fetal circulation in newborns may be related to constriction of the ductus arteriosus not diagnosed during intrauterine life. Group B had a lower severity but a risk of an unfavorable evolvement, suggesting a distinct alteration.

Comparative StudyBehavior of inflammatory markers of myocardial injury in cardiac surgery: laboratory correlation with the clinical picture of postpericardiotomy syndrome.
To verify the association of serum markers of myocardial injury, such as troponin I, creatinine kinase, and creatinine kinase isoenzyme MB, and inflammatory markers, such as tumor necrosis factor alpha (TNF-alpha), C-reactive protein, and the erythrocyte sedimentation rate in the perioperative period of cardiac surgery, with the occurrence of possible postpericardiotomy syndrome. ⋯ The patients who met the clinical criteria for postpericardiotomy syndrome were significantly younger than the others were. Serum markers for tissue injury and inflammatory response were not different in the clinically affected group, and did not correlate with the different types and duration of surgery or with extracorporeal circulation.

Impact of cerebral cardiopulmonary resuscitation maneuvers in a general hospital: prognostic factors and outcomes.
To assess survival of patients undergoing cerebral cardiopulmonary resuscitation maneuvers and to identify prognostic factors for short-term survival. ⋯ The presence of VF/VT as the initial rhythm, shorter times of cerebral cardiopulmonary resuscitation and of cardiopulmonary arrest, and a greater value of BP prior to cardiopulmonary arrest were independent variables of better prognosis.

Assessment of factors that influence weaning from long-term mechanical ventilation after cardiac surgery.
To analyze parameters of respiratory system mechanics and oxygenation and cardiovascular alterations involved in weaning tracheostomized patients from long-term mechanical ventilation after cardiac surgery. ⋯ Data on respiratory system mechanics and oxygenation were not parameters for assessing the success or failure. Cardiac dysfunction and time of cardiopulmonary bypass, however, significantly interfered with the success in weaning patients from mechanical ventilation.
