He was readmitted 1 month after discharge with progressive cardiac dysfunction. Myocardial scintigraphy excluded ischaemia, and computed tomography revealed severe true lumen stenosis at the distal FET, resulting in an elevated left ventricular afterload. Thoracic endovascular aortic repair (EVAR) to expand the true lumen resulted in gradual improvement in cardiac function. However, there was progressive dilation of the descending and thoracoabdominal aorta: 26\u2005mm at onset and 32 and 46\u2005mm at 2 and 6 months postoperatively, respectively. To close distal re-entries, EVAR was performed after 2 months. His brain natriuretic peptide level decreased from 2901 to 142\u2005pg\/ml over 8 months; open abdominal aortic replacement was performed 9 months after the onset, after sufficient cardiac function recovery (ejection fraction = 40%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>True lumen stenosis is a substantial reversible cause of cardiac dysfunction after type A dissection surgery.
