Objectives: Because access to sleep recordings is limited, there is a need for new reliable diagnostic tools for pediatric obstructive sleep apnea-hypopnea syndrome (OSAHS) diagnosis. A score calculated from a 30 minutes-home sleep videotape recording has already been proposed in 1996 with interesting results. The main objective of this pilot study was to assess the reliability of a similar score applied to reference PSG video recordings and calculated on two different time windows (30 and 10 minutes). Methods: Sixteen children suspected of OSAHS, aged between two and ten years, underwent video recording during overnight PSG. Video analysis was made during the second complete sleep cycle. A 30-minute risk score (RS30) and a 10-minute risk score (RS10) were established by analyzing seven parameters. The RS30 and RS10 were correlated with clinical examination data, a sleep questionnaire, the obstructive-apnea-hypopnea index (OAHI) and the oxygen desaturation index (ODI) from synchronized PSG results. Results: There was a significant correlation between both the RS30 and RS10, the OAHI and ODI. A RS30 ≥ 6.09 was predictive of an OAHI ≥ 5 per hour with a sensitivity of 83% and a specificity of 90%. A RS10 ≥ 6.50 was predictive of an OAHI ≥ 5 per hour with a sensitivity of 67% and a specificity of 100%. Conclusion: A risk score based on PSG video recordings shows a good correlation with PSG results, confirming previous reports. Further work should focus on applying this risk score to home sleep video recordings for the diagnosis of pediatric OSAHS.

Background We evaluated short- and mid-term outcomes with use of aortic valve-sparing root replacement to treat bicuspid aortic valves. Methods From December 2007 to January 2022, all patients with bicuspid aortic valves who underwent aortic root replacement using Tirone’s procedure were included. This study based on department database information for retrospective and follow-up data. Results Among 51 adults undergoing aortic root replacement using Tirone’s procedure, the mean age was 47.4±12.5 years, and most were men (92.2%). Three presented with a dysmorphic syndrome and one had Marfan’s syndrome. All patients were alive at 30 days, and as of January 2022, 45 were alive, two were lost to follow-up, and there were four noncardiac deaths. Two patients had infectious endocarditis and needed a Bentall’s procedure. One patient had a double biologic valve replacement in the context of severe mitral insufficiency with moderate aortic stenosis at 4.5 years post-procedure. Echocardiographic follow-up showed a left ventricular ejection fraction of 63±7% (n=36), V max 2±0.6 m/s (n=17), and a mean gradient of 9.4±5.4 mmHg (n=27). No patients had grade 3 or 4 aortic regurgitation, one patient had grade 2, and four had grade 1. Conclusion Tirone’s procedure is an option for bicuspid aortic valve surgery, with good safety and outcomes, especially in younger patients.
