Аннотация
BACKGROUND: Left atrial dissection is a rare and a potentially fatal complication of cardiac surgery. Multi-modal imagery is helpful for the diagnosis and to guide the treatment.
CASE PRESENTATION: We report the case of a 66-year-old female patient who underwent a combined mitral and aortic valve replacement for degenerative valvular disease. She presented an infectious endocarditis revealed by a third-degree atrioventricular bloc and had a redo mitral- and aortic valve replacement. Mitral valve was inserted in supra-annular position due to annular destruction. Post-operative course was marked by a refractory acute heart failure explained by a left atrial wall dissection confirmed by transoesophageal echocardiography and synchronized cardiac CT-scan. Surgical treatment was theoretically indicated but considering the high risk of a third surgery, a palliative care support was collegially decided.
CONCLUSIONS: Left atrial dissection can occur after a redo surgery and supra-annular mitral valve implantation. Multi-modal imagery including transoesophageal echocardiography and cardiac CT-scan is helpful for the diagnosis.
