Objective To compare the clinical outcomes of mitral valvuloplasty (MVP) and mitral valve replacement (MVR) for infective endocarditis, and to investigate the effect of MVP under different surgical risks. Methods A retrospective study was done on the patients with mitral infective endocarditis, who underwent surgical treatment in our department from January 2018 to March 2022. According to the procedures, the patients were divided into a MVP group and a MVR group. Propensity score matching method was applied with a ratio of 1:1 to eliminate the biases. The early and midterm outcomes were compared between the two groups after matching. According to the European System for Cardiac Operative Risk Evaluation Ⅱ(EuroSCORE-Ⅱ), the effect of MVP was compared between high and low risk patients. Results A total of 195 patients were collected. There were 141 patients in the MVP group (120 males, 85.1%) and 54 patients in the MVR group (41 males, 75.9%). The mean follow-up time was (34.0±16.1) months. Patients in the MVP group were younger [(42.7±14.6) years vs. (56.8±13.0) years, P<0.001] and had better preoperative conditions. The patients in the MVP group had a shorter ICU stay [3.0 (2.0, 5.0) d vs. 4.0 (3.0, 8.0) d, P=0.004], and lower incidences of low cardiac output syndrome (0.7% vs. 9.3%, P=0.007), in-hospital mortality (0.0% vs. 3.7%, P=0.023), and follow-up mortality (4.3% vs. 15.4%, P=0.007). However, after 1:1 propensity score matching, there were no statistical differences in the baseline data or postoperative and follow-up adverse events between the two groups (P>0.05). Also, there was no statistical difference in the mortality of high-risk patients between MVP and MVR group (P>0.05). There was no statistical difference in the reoperation or recurrent severe mitral regurgitation between high and low-risk patients in the MVP group (P>0.05). Conclusion MVP is feasible for treating mitral lesions caused by infective endocarditis with good early and midterm outcomes. For patients with severer preoperative conditions, if the leaflet damage is not severe, MVP may be a viable option, but validation with larger sample sizes is needed.

Objective To summarize the clinical features of infectious intracranial aneurysm (IIA) related to infective endocarditis (IE) and share our experiences in the diagnosis and treatment of IIA. Methods A retrospective analysis was conducted on the clinical data of 554 patients who underwent cardiac surgery for IE at the Department of Cardiac Surgery, Guangdong Provincial People's Hospital from September 2018 to August 2023. Patients with secondary IIA were included and reviewed. Based on the treatment strategies, patients were stratified into two groups: an antibiotic-only group and an endovascular treatment group. Results The cohort comprised 21 males and 10 females, with a median age of 33 years (IQR 26-53). Fifteen (48.4%) patients showed no significant neurological symptoms before IIA diagnosis. Seven patients received antibiotic therapy alone, while 24 underwent additional endovascular embolization, achieving technical success in 23 (95.8%) patients. The median interval between endovascular embolization and cardiac surgery was 2 days (IQR 0-6), with 9 patients undergoing concurrent procedures. In the antibiotic-only group, 3 (42.9%) patients suffered fatal IIA rupture. In contrast, only 1 (4.2%) death due to aneurysm rupture occurred in the endovascular treatment group. All surviving patients recovered well without new neurological deficits. Conclusion Routine neuroimaging screening for IIA is critical in IE patients. For those requiring cardiac surgery, endovascular embolization combined with antimicrobial therapy represents a reasonable strategy to mitigate rupture risks and improve outcomes.

Objective:To compare the short-term clinical outcomes of thoracoscopy-assisted minimally invasive mitral valve surgery(minimally invasive cardiac surgery MICS group)versus conven-tional median sternotomy mitral valve surgery(conventional surgery group),including surgical metrics,postoperative complications,transfusion volume,and in-hospital mortality rate.Methods:A ret-rospective analysis was performed for 141 patients who underwent mitral valve surgery in Chongqing General Hospital from January 2021 to June 2022,and these patients were divided into MICS group with 42 patients and conventional surgery group with 99 patients.Propensity score matching at a ratio of 1∶1 was performed to ob-tain 82 patients,with 41 patients in each group,and related data were collected and compared,including surgical procedure,cardiopul-monary bypass time,postoperative ventilation time,transfusion volume,and in-hospital mortality.Results:There were no significant differences between the MICS group and the conventional surgery group in sex,age,cardiac functional grading,and comorbidity with diabetes or hypertension,and as for the surgical procedure,there was no significant difference between the two groups in the number of patients undergoing atrial fibrillation radiofrequency ablation(11/42 vs.26/99,P=0.583)or tricuspid valvuloplasty(14/42 vs.39/99,P=0.310).Compared with the conventional surgery group,the MICS group had significantly longer aortic cross-clamp time[(122±48)min vs.(91±50)min,P=0.031]and cardiopulmonary bypass time[(180±73)min vs.(136±72)min,P=0.033],while there was no significant difference in postoperative ventilation time between the two groups after surgery[18.6(12.0,36.2)h vs.24.0(15.5,33.1)h,P=0.265].There was no significant difference in the number of patients with acute renal failure after surgery between the MICS group and the conventional surgery group[grade 1:3(42)vs.7(99);grade 2:0(42)vs.2(99);grade 3:1(42)vs.9(99);P=0.398].There was also no significant difference in the number of patients receiving hemodialysis after surgery between the two groups[1(42)vs.4(99),P=0.531].The MICS group had a significantly lower postoperative transfusion volume than the conventional surgery group[120(80,240)mL vs.400(200,600)mL,P=0.002],and there was no significant difference in in-hospital mortality rate between the two groups[1(42)vs.2(99),P=0.665].After propensity score matching,there were no significant differences between the two groups in general characteristics(sex,age,and comorbidities).Compared with the conventional surgery group,the MICS group had longer cardiopulmonary bypass time[(165±73)min vs.(122±74)min,P=0.053]and aortic cross-clamp time[(119±48)min vs.(98±52)min,P=0.073]and a significantly lower postoperative transfusion volume[120(80,240)mL vs.400(200,600)mL,P<0.001].There were no significant differences between the two groups in 30-day in-hospital mortality rate and postoperative compli-cations(including acute renal failure and requirement for hemodialysis).Conclusion:Thoracoscopy-assisted minimally invasive mitral valve surgery has comparable short-term clinical outcomes and safety to conventional sternotomy.Although MICS requires longer cardiopulmonary bypass time and aortic cross-clamp time,it has relatively low requirements for postoperative transfusion and shows favorable clinical outcomes.

OBJECTIVES: To investigate the medium- and long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation for treatment of iliac vein stenosis with lower extremity deep venous thrombosis (LEDVT). METHODS: Clinical and follow-up data of 125 patients with iliac vein stenosis and LEDVT who underwent PMT and stent implantation at five hospitals in northern Zhejiang province from January 2017 to June 2021 were collected. The thrombus clearance rate, thrombus recurrence rate, patency rate of iliac vein stents and post-thrombotic syndrome (PTS) occurrence rate were documented, and safety indicators such as bleeding, death, pulmonary embolism, stent fracture and displacement were assessed. RESULTS: Among 125 patients, for clearance of limb thrombosis, there were 8 cases of grade I (6.4%), 10 cases of grade II (8.0%), and 107 cases of grade III (85.6%). Patients were followed up for a median period of 74 months. According to the Villalta score, the recurrence rates of limb thrombosis at 12, 24 and 36 months were 8.48%, 8.93% and 10.91%; the iliac vein patency rates were 91.52%, 91.07%, and 89.09%; and the incidences of PTS were 5.08%, 5.36% and 6.36%, respectively. There were no major adverse events such as death, massive pulmonary embolism or severe hepatic and renal insufficiency, and no readmission intervention events due to stent fracture or other incidence were found. CONCLUSIONS PMT combined with iliac vein stent implantation is effective for patients with iliac vein stenosis complicated by LEDVT with good medium- and long-term efficacy and safety, which is worthy of clinical application.

Agenesis of the dorsal pancreas(ADP)is an extremely rare congenital pancreatic malformation characterized by the absence or hypoplasia of the pancreatic body and tail.Its pathogenesis is closely related to abnormal embryonic development of the ventral and dorsal pancreatic buds,governed by a complex network of transcription factors,including HLXB9,HNF1B,PDX1,PTF1A,GATA4,and GATA6.The clinical spectrum of ADP is highly variable,ranging from asymptomatic cases to manifestations such as abdominal pain,diabetes mellitus,or pancreatitis.Imaging modalities-including ultrasonography,CT,magnetic resonance cholangiopancreatography,and endoscopic retrograde cholangio-pancreatography-serve as the main diagnostic tools,with characteristic findings of absent pancreatic body and tail accompanied by compensatory enlargement of the pancreatic head.ADP is frequently associated with congenital anomalies of the kidney,biliary tract,cardiovascular system,or genital organs.Management is primarily symptomatic,with insulin replacement for diabetes and pancreatic enzyme supplementation for exocrine insufficiency.Advances in genetic sequencing and stem cell research have deepened understanding of the pathogenesis,genetic background,and potential therapeutic strategies of ADP.This review summarizes current progress in embryology,genetics,clinical features,diagnosis,and treatment of ADP,aiming to improve clinical recognition and guide future investigations.

Objective:To evaluate the safety, efficacy, advantages and disadvantages of the modified double-orifice valve plasty via total thoracoscopy for partial atrioventricular septal defect(PAVSD) through a retrospective analysis of early postoperative results.Methods:Patients diagnosed with PAVSD who underwent the standardized modified double-orifice valve plasty via total thoracoscopy between September 2023 and August 2024 were retrospectively enrolled. Baseline characteristics, surgical parameters, and follow-up outcomes were systematically analyzed.Results:A total of 14 patients(6 males, 8 females) were included, with a mean age of(32.9±15.5) years old and body weight of(55.1±11.6) kg. All procedures were successfully completed. The mean operative time, cardiopulmonary bypass time, and aortic cross-clamp time were(266.6±67.2) min, (160.7±34.2) min, and(97.0±31.1) min, respectively. Postoperative ICU stay, hospital stay, and total hospitalization duration were(1.7±1.1) days, (6.4±4.2) days, and(12.6±4.5) days, respectively. The mean follow-up duration was(7.9±3.6) months. Preoperatively, left atrioventricular valve regurgitation(LAVVR) was graded as mild, moderate, or severe in 5, 4, and 5 patients. Postoperatively, 13 patients exhibited mild or less LAVVR, with 1 case of moderate regurgitation. By 3 months, all patients demonstrated LAVVR of mild or lower severity, which remained stable through follow-up. Peak LAVV gradients were(4.6±2.7) mmHg(1 mmHg=0.133 kPa)(range: 1.8-10.2 mmHg) postoperatively, improving to(3.6±0.6) mmHg(3.2-4.0) mmHg at 1 year. Right atrioventricular valve regurgitation improved from preoperative moderate-severe(50.0%) to LAVVR of mild or lower severity in all patients by 3 months. No mortality, residual shunts, or high-grade atrioventricular block occurred through follow-up. By 1 month, NYHA functional class improved to Ⅰ in all patients, which remained stable through follow-up.Conclusion:Standardized modified double-orifice valve plasty via total thoracoscopy for PAVSD demonstrates safety, minimal invasiveness, and rapid recovery, with favorable early outcomes.

Objective:Hearing loss can seriously affect mental health status, and this study aims to investigate the influence of hearing health status on depressive symptoms among middle-aged and older individuals in the community.Methods:From June to December 2023, a stratified random sampling method was employed to select 1 238 community-dwelling middle-aged and elderly people aged 45 years and above from four cities (Hangzhou, Shanghai, Baoding, and Zhengzhou) as research subjects. A questionnaire survey was conducted to collect the subjects′ basic information, hearing health status [assessed by the Hearing Handicap Inventory for Adults-Screening Version (HHIA-S)], and depressive symptoms [assessed by the Geriatric Depression Scale-15 (GDS-15)]. T-tests, rank-sum tests and chi-square tests were used for univariate analysis, while, multiple linear regression and binary Logistic regression were applied to analyze the relationship between hearing health status and depressive symptoms.Results:A total of 1 183 community-dwelling middle-aged and elderly people aged 45 years and above were included in the final analysis (464 males and 719 females, aged from 45 to 96 years). The detection rate of hearing loss was 35.3%(418/1 183), while, the detection rate of depressive symptoms was 9.89%(117/1 183). Age, level of interaction with children, self-rated health, perceived loneliness, and hearing health significantly influenced depressive symptoms among older adults residing in the community ( P<0.05). Individuals with moderate to severe hearing loss ( β=2.04, 95% CI: 1.47, 2.62) exhibited higher GDS-15 scores compared to those without hearing impairment. Furthermore, after correcting for sex, age, marital status, monthly per capita family income, education, residence, smoking status, alcohol use, use of psychotropic medication (anxiolytic or depressant), number of illness, self-health assessment, and autonomy, middle-aged and older adults with mild to moderate hearing loss ( OR=2.89, 95% CI: 1.76, 4.88) and severe hearing loss ( OR=5.79, 95% CI: 3.05, 11.01) demonstrated an increased likelihood of experiencing depression. Conclusions:The degree of hearing loss in community-dwelling middle-aged and elderly individuals is closely associated with the risk of depressive symptoms. Therefore, it is imperative to enhance hearing health screening and to provide mental health support to individuals with hearing loss, in order to mitigate the onset and progression of depressive symptoms.
