Eventos catastróficos associados ao tratamento da comunicação interatrial tipo ostium secundum: razões para não se subestimar este tipo de cardiopatia congênita

Abstract

Objective: The present article was motivated by the frustrating experiences with four patients who underwent surgical treatment of ostium secundum atrial septal defect (ASD-II) and who died in extremely dramatic circumstances.Method: This is a retrospective study based on clinical data. The bibliographical research included: paradoxical thromboembolism (cerebral, pulmonary or mesenteric), central nervous system vascular malformations and anomalous vena cava connections. This research was based on possible events, unexpected and catastrophic, that could have directly caused the patients' deaths.Results: All patients were female. The operations were performed under cardiopulmonary bypasses with less than 20 minutes of aortic cross-clamping. The causes of death were: non-occlusive intestinal ischemia, rupture of a cerebral aneurysm of the anterior communicating artery, cor pulmonale associated with pulmonary arterial hypertension and thromboembolism and probable cerebral thromboembolism in a child that needed to be reoperated to correct anomalous inferior vena cava drainage into the left atrium.Conclusion: Even being technically easy to treat, death due to atrial septal defects in extremely dramatic circumstances is possible, so "Do not underestimate atrial septal defects in congenital heart surgery".

Adult congenital heart disease: experience with the surgical approach

“…Albeit our patients with III and IV functional class corresponded to only 11% before operation, two of our early deaths occurred in patients with not complex forms of congenital heart disease, ASD and partial atrioventricular septal defect. Despite the relative benignity of the intervention in these types of defects, the possibility of complications has already been reported [20]. Another fact which certainly influences results is the number of operated patients.…”
