Objective To summarize and analyze the surgical approach and early prognosis of repairing adult aortic closure insufficiency with the Florida sleeve procedure. Methods The patients with aortic insufficiency who underwent Florida sleeve repair in the First Hospital of Nanjing Medical University between August 2020 and May 2024 were selected. Their general data, perioperative conditions, and echocardiographic data before, during, and after the procedure and at follow-up were analyzed. Result Fifteen patients were included, consisting of 12 males and 3 females, aged 33-71 (53.5±12.4) years. Preoperative echocardiography indicated that there was 1 patient of rheumatic disease, 7 patients of degenerative disease, 4 patients secondary to aortic aneurysm, and 3 patients of bicuspid aortic valve. The severity distribution included 2 patients of severe insufficiency, 4 patients of moderate-to-severe insufficiency, 5 patients of moderate insufficiency, and 4 patients of mild-to-moderate insufficiency. The mean cardiopulmonary bypass time was (135.0±40.0) minutes, the aortic cross-clamp time was (109.9±38.6) minutes, and the median ICU stay was 1 day. No mortality was recorded within 30 days postoperatively. Follow-up echocardiography showed that the valve regurgitation, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, and sinus diameter all achieved the desired outcomes. Conclusion Florida sleeve repair for aortic valve in patients with a sinus diameter less than 50 mm not only effectively improves hemodynamics in adults with aortic insufficiency, but also has the advantages of low surgical risk and rapid postoperative recovery, making it a promising procedure for clinical application.
Objective To compare surgical outcomes of Stanford type A acute aortic dissection between operations at midnight and daytime. Methods From January 2004 to March 2013，195 patients with Stanford type A acute aortic dissection received surgical treatment in Nanjing Hospital Affiliated to Nanjing Medical University （Nanjing Cardiovascular Disease Hospital）. Patients with identical or similar propensity scores were matched from 127 patients who underwent emergency operation at daytime and 68 patients who underwent emergency operation at midnight. A total of 58 pairs of matched patients which had the same or similar propensity score were selected in daytime surgery group （n=58，43 males and 15 females，47.7±14.6 years） and midnight surgery group （n=58，45 males and 13 females，48.3±14.6 years）. Operation time，postoperative chest drainage，mechanical ventilation time，postoperative incidence of dialysis and tracheostomy，length of ICU stay and in-hospital mortality were compared between the daytime group and midnight group. Results A total of 58 pair of patients were matched in this study. There was no statistical difference in postoperative incidence of tracheostomy ［19.0% （11/58） vs. 6.9% （4/58），P=0.053］ or in-hospital mortality ［8.6% （5/58） vs. 6.9%（4/58），P=0.729］ between the midnight group and daytime group. Operation time （485.7±93.5 minutes vs. 428.5±123.3 minutes，P=0.048），postoperative chest drainage （979.5±235.7 ml vs. 756.6±185.9 ml，P=0.031），mechanical ventilation time （67.9±13.8 hours vs. 55.7±11.9 hours，P=0.025），postoperative incidence of dialysis ［17.2% （10/58） vs. 5.2%（3/58），P=0.039］ and length of ICU stay （89.4±16.2 hours vs. 74.8±12.5 hours，P=0.023） of the midnight group weresignificantly longer or higher than those of the daytime group. A total of 107 patients were followed up for 4-6 months after discharge. During follow-up，there was no late death. Among the 13 patients who required postoperative dialysis，12 patientsno longer needed regular dialysis. Conclusion Emergency operation at midnight does not increase in-hospital mortalitybut increase some postoperative morbidity in patients with Stanford type A acute aortic dissection. Whether at midnight or daytime，better preoperative preparation and surgeons’ vigor are needed for timely surgical treatment for patients with Stanford type A acute aortic dissection.
