In recent years,the Ross procedure has been increasingly applied in the treatment of aortic valve disease in children and young patients.However,right ventricular outflow tract(RVOT)reconstruction in this procedure often relies on allogeneic or artificial materials,which may lead to complications such as calcification and valve dysfunction.This article reports a case of protective Ross procedure using completely autologous tissue to construct a right ventricular-pulmonary artery(RV-PA)conduit.The patient was an 11-year-old male who presented with severe aortic stenosis combined with regurgitation.During the operation,his dilated ascending aortic wall and fresh pericardium were used to construct an autologous valved conduit for RV-PA reconstruction.This innovative technique achieves RV-PA reconstruction without allogeneic tissue,provides a new technical approach for the Ross procedure.Short-term results are satisfactory and the medium-and long-term outcomes require further follow-up verification.

The deep integration of interventional medical imaging and artificial intelligence(AI)technologies is promoting the intelligence of the entire diagnosis and treatment process and significantly improving the accuracy and safety of minimally invasive operations,and the relative hotspots includes intelligent detection of anatomical landmarks,automatic segmentation of lesions,multimodal diagnosis and treatment and decision-making system,as well as navigation of interventional operations.The future trends will emphasize the construction of integrated multi-modal diagnosis and treatment platform,optimization of real-time reasoning engines and establishment of explicable decision-making system,in order to promote the transformation of precision medicine from theoretical innovation to large-scale clinical application.The research progresses in diagnosis and treatment methods combining interventional medical imaging with AI were reviewed in this article.

Objective To analyze the risk factors and prognosis of patients with advanced lung cancer complicated with immune checkpoint inhibitor-related pneumonitis(CIP).Methods A total of 220 patients with advanced lung cancer who were treated at Ganzhou Cancer Hospital from January 2022 to October 2024 were selected as the research subjects.The patients were divided into non-CIP group(n=179)and CIP group(n=41)based on whether they had concurrent CIP.Compare the clinical characteristics of two groups of patients and analyze the related influencing factors of patients with advanced lung cancer complicated with CIP.Results There were statistically significant differences in age,gender,underlying pulmonary diseases,smoking history,history of thoracic radiotherapy,treatment plans,serum albumin(Alb),platelet to lymphocyte ratio(PLR),neutrophil to lymphocyte ratio(NLR),and absolute lymphocyte count(ALC)between two groups of patients(P＜0.05).Multivariate Logistic regression analysis showed that age,underlying pulmonary diseases,treatment plan,Alb,PLR,NLR,and ALC were all influencing factors for patients with advanced lung cancer complicated with CIP(P＜0.05).The 90-day cumulative survival rate of patients in CIP group was significantly lower than that in non-CIP group(58.54％ vs.77.09％,x2=5.918,P=0.015).With the increase of CIP classification,the 90-day cumulative survival rate of patients showed a downward trend(P＜0.05).Conclusion The incidence of CIP in patients with advanced lung cancer is relatively high.Age,underlying pulmonary diseases,treatment plan,and levels of Alb,PLR,NLR,and ALC are all influencing factors.CIP can have adverse effects on the prognosis of patients.

Artificial chord is a mature mitral valve repair technique, especially in adult mitral valve repair. It is still challenging to repair mitral valve in children with artificial chords because the quality of mitral valve is soft and immature. There are some differences in the methods of suture, the choice of suture size and the number of artificial chords. Although the artificial chords could not grow naturally, we found through the long-term research that most children did not have mitral valve restriction or even chords rupture due to itself can compensate through the growth of the flap and papillary muscle. This article summarizes the recent research progress on the treatment of mitral valve insufficiency in children with artificial chords, providing reference for clinical treatment.

Objectives:This study aims to investigate optimal surgical management strategies for pediatric patients diagnosed with volume-overloaded mitral regurgitation. Methods:A comprehensive retrospective analysis was conducted on a cohort of 110 pediatric patients who underwent primary mitral valve repair for volume-overloaded mitral regurgitation at Fuwai Hospital between April 2020 and March 2022.The cohort,with an average age of(14.5±15.1)months and 38.2%males,was divided into standardized group for patients receiving 3-step standardized mitral valvuloplasty(n=69)and annuloplasty group for patients undergoing annuloplasty only(n=41).After propensity score matching,a total of 38 pairs of patients were included,comparing the primary endpoint(functional mitral failure and postoperative heart failure)between the two groups. Results:Over a median follow-up of 26.3(19.8,32.9)months,and with a median echocardiographic follow-up of 11.9(7.5,14.8)months,no death was recorded.Among the cases,one patient(0.8%)necessitated unplanned reoperation;and seven patients(6.4%)experienced a recurrence of moderate-severe mitral regurgitation as observed through echocardiography beyond 6 months post-surgery.Additionally,nine patients developed heart failure at one month post-discharge.Above events were similar between the two groups.Following propensity score matching,patients in the standardized group demonstrated significantly longer cardiopulmonary bypass and aortic cross-clamp times compared to the annuloplasty group(both P＜0.05),other outcomes were similar between the two groups.Subgroup analysis based on age indicated that infants(＜1 year old)in the standardized group exhibited a significantly lower incidence of major endpoint events compared to the annuloplasty group.Additionally,postoperative echocardiography in annuloplasty group indicated that Z score of left ventricular end diastolic diameter was still greater than 2 during the latest follow-up. Conclusions:Patients with volume-overloaded mitral regurgitation in the standardized group exhibited comparable perioperative recovery and postoperative outcomes as in the annuloplasty group.For pediatric patients suffering from volume-overloaded mitral regurgitation,particularly those under one year of age,the standardized surgical approach exhibited reduced rates of heart failure and major endpoint events,and this strategy is more suitable for this patient group.
