Objective: Frailty has been noticed as an important preoperative risk factor for cardiac surgery. The purpose of this study was to evaluate the effect of frailty on the rehabilitation process and walking ability after cardiac surgery. Methods: A total of 213 patients aged 65 years or older who underwent elective cardiac surgery at our hospital between August 2018 and October 2020 and who underwent a preoperative frailty assessment were included. The patients were divided into two groups: group F with frailty and group N without frailty, and the perioperative factors, postoperative course, and walking ability in both groups were examined. Results: Of all patients, 70 (33%) were diagnosed as frail. In the preoperative factors, gait speed and grip strength were significantly lower in group F, and there were more cases of sarcopenia and malnutrition. There was no significant difference in surgical factors between the two groups, except for a bias in the surgical category. In the postoperative course, there were no significant differences in intubation time, ICU stay, postoperative complications, or hospital stay between the two groups, but more patients in group F were transferred to another hospital. In the F group, the start of walking and the day of achieving 100 m walking were significantly delayed, and the number of patients who achieved 300 m walking was 52 (74%), which was significantly lower than 197 (89%) in the N group. The cutoff value of gait speed was 0.88 m/s. Conclusions: Frailty was associated with delayed rehabilitation and reduced walking ability after cardiac surgery, and increased hospital transfers. In addition, the preoperative gait speed was adopted as one of the factors related to the possibility of a 300 m walk after surgery. We believe that preoperative rehabilitation is a promising strategy to improve the condition of frail patients who require cardiac surgery.

<p>A 79-year-old man, who had a history of intravesical instillations of bacillus Calmette-Guérin (BCG) therapy for urinary bladder cancer, developed bloody sputum 4 years after BCG therapy. BCG was detected from the sputum by detailed examination. Medical therapy for tuberculosis (TB) was started, but bloody sputum continued. Computed tomography (CT) for the chest was performed to evaluate the state of TB, and surprisingly, found impending rupture of tuberculosis mycotic thoracic aneurysm. He was emergently transferred to our hospital. CT revealed that the aneurysm made a lump with surrounding lung and lymph nodes. It seemed to be quite difficult to dissect and to be quite high risk to perform graft replacement with pneumonectomy. On the other hand, TB infection was controlled with antibiotic therapy. Thus we chose debranch TEVAR for this complicated situation. His bloody sputum regressed soon after the procedure and disappeared during his hospitalization. He was discharged home on POD 13 without serious complication and continued to have antibiotic therapy under the instruction of his primary physician.</p>

<p>Endovascular treatment for chronic aortic dissection in patients with Marfan syndrome is still controversial. A 60-year-old man developed an extended chronic type B dissection involving the aortic arch and thoraco-abdominal aorta with a large entry at the distal aortic arch and patent false lumen. He had undergone David procedure for type A aortic dissection at age 42, and aortic valve replacement for recurrent aortic valve insufficiency at 58, which was complicated with mediastinitis. He also suffered drug-induced interstitial pneumonitis. Considering his complicated surgical history and impaired pulmonary function, conventional graft replacement of thoraco-abdominal aorta was thought to be quite a high risk. Thus, we chose debranch TEVAR with a staged approach. First, debranching and Zone 0 TEVAR with the chimney technique were performed. Then, 4 months later, abdominal debranching and TEVAR was performed. The patient tolerated both procedures well and was discharged home. Two years after last procedure, he is in good condition and computed tomography shows that complete entry closure and false lumen had thrombosed. This strategy may be worthy to be considered even for a patient with Marfan syndrome, in case the patient's condition is unsuitable for conventional surgery.</p>
