Abstract： Quality of life （QOL） refers to an individual’s perception and subjective evaluation of their health and well-being, and has become an important index to evaluate the outcomes of clinical treatment in the last past decades. There are a large number of different instruments to evaluate QOL, and the 36-Item Short Form Health Survey （SF-36） is currently one of the most widely used instruments. In recent years, SF-36 has been used to evaluate QOL of valvular heart disease patients to investigate the risk factors those influence their postoperative QOL, provide more preoperative evaluation tools for clinical physicians, and improve postoperative outcomes of patients with valvular heart disease. However, it is now just the beginning to use SF-36 to examine QOL of valvular heart disease patients. Because of significant differences in sample size, follow-up period, country and culture, current research has some controversial results. This review focuses on the progress in evaluating QOL in postoperative patients with valvular heart disease using SF-36.
Clinical application history of prosthetic heart valves has been over five decades, and mechanical heart valves have satisfactory clinical outcomes for surgical treatment of valvular heart disease. The development history of mechanical heart valves experienced from the first generation of ball valves and caged disc valves to the second generation of single tilting disc valve, and to the third generation of bileaflet valves. In 1960， ball valve was first used for heart valve replacement in abroad. In 1963， China-made ball valve was also produced and used in clinical practice. In 1969， the second generation of single tilting disc valve was developed in abroad. In 1978， China-made single tilting disc valve was produced and widely used in clinical practice with satisfactory clinical outcomes. Since 1980 when it was first produced， bileaflet valve has taken the place of above 2 types of valves for its excellent performance, and become the mainstream product all over the world. Currently, the development of China-made bileaflet valves has lagged behind， and domestic mechanical heart valve market has almost been monopolized by foreign bileaflet valve products. Therefore, the development of ideal China-made mechanical heart valve deserves further research.
ObjectiveTo investigate clinical outcomes and summarize perioperative management experience of heart valve replacement (HVR)in elderly patients. MethodsWe retrospectively analyzed clinical data of 47 elderly patients undergoing HVR in Affiliated Hospital of Xuzhou Medical College from January 2011 to May 2014. There were 19 male and 28 female patients with their age of 60-79 years. There were 35 patients with rheumatic heart disease, 10 patients with degenerative valvular disease, and 2 patients with congenital bicuspid aortic valve. Preoperatively, there were 23 patients in NYHA functional class Ⅱ, 19 patients in class Ⅲ, and 5 patients in class Ⅳ. All the patients received HVR under cardiopulmonary bypass (CPB), and some patients received concomitant tricuspid valvuloplasty (TVP), left atrial thrombectomy or coronary artery bypass grafting (CABG). Postoperative mortality, morbidity and heart function improvement were evaluated. ResultsTwenty-seven patients received mitral valve replacement (MVR), 15 patients received aortic valve replacement (AVR), and 5 patients received MVR+AVR. Concomitantly, 4 patients received TVP, 3 patients received left atrial thrombectomy, and 6 patients received CABG. Operation time was 138-412 (196±52)minutes, CPB time was 48-301 (108±33)minutes, aortic cross-clamping time was 34-196 (87±21)minutes, and length of hospital stay was 12-31 (19±5)days. There was no intraoperative death, and 2 patients (4.3%)died postoperatively because of left ventricular failure and multiple organ dysfunction syndrome respectively. Twenty-three patients (51.1%)had postoperative complications including respiratory failure in 6 patients, pulmonary infection in 5 patients, arrhythmias in 5 patients, wound infection in 2 patients, pleural effusion in 2 patients, low cardiac output syndrome in 2 patients, and acute renal failure in 1 patient. Forty-five survival patients were followed up by telephone, online video and at the outpatient department for 1-32 months, and follow-up rate was 100%. There were 11 patients in NYHA functional classⅠ, 32 patients in class Ⅱ, and 2 patients in class Ⅲ. ConclusionAccording to clinical characteristics of elderly patients with valvular heart disease, meticulous surgical techniques and perioperative management can effectively reduce mortality and morbidity after HVR.
Objective To propose a whole-life cycle management model for valvular heart disease (VHD), systematically elucidate its underlying logic and implementation pathways, and concurrently review and analyze its preliminary application outcomes. Methods Since 2020, West China Hospital of Sichuan University has established a management system encompassing "assessment-decision-intervention-follow-up", including: (1) a risk-stratified, tiered management pathway; (2) six core functions ("promotion, screening, prevention, diagnosis, treatment, and rehabilitation") coordinated by disease-specific managers; (3) an intelligent decision support information platform; and (4) a collaborative network of multidisciplinary teams and regional academic alliances. To evaluate the effectiveness of this management model, we retrospectively included three cohorts: (1) the population screened by echocardiography from 2020 to 2024, analyzing the detection rate of aortic valve disease and risk stratification; (2) patients enrolled in the whole-life cycle management from April 2021 to December 2024, assessing follow-up outcomes, hospital satisfaction, and changes in quality of life; (3) patients who underwent transcatheter aortic valve replacement (TAVR) from January 2022 to January 2024, evaluating the one-year all-cause mortality rate, perioperative complications, and improvements in New York Heart Association (NYHA) classification. Results Between 2020 and 2024, a total of 583 874 individuals underwent echocardiographic screening. A total of 48 089 patients with aortic valve disease were identified, including 3 401 (7.1%) high-risk patients, 18 657 (38.8%) moderate-risk patients, and 26 031 (54.1%) low-risk patients. Among them, 2 417 patients were enrolled in whole-life cycle management. Patient satisfaction scores showed a yearly increase, rising from 73.89 points before 2020 to 93.74 points in 2024. The 1-year mortality rate in the TAVR cohort decreased to 5.3%, significantly lower than the 8.2% observed under early standard management between 2014 and 2019 (P<0.01). Conclusion Through process optimization and resource integration, the VHD whole-life cycle management model has demonstrated significant effectiveness in standardizing diagnostic and follow-up procedures, enhancing patient satisfaction and quality of life, and reducing mortality. These outcomes highlight its practical value for broader implementation in China.
Abstract: Objective To evaluate myocardial protection effect of different myocardial protective strategies for patients undergoing double valve replacement （DVR） . Methods From Jun. 2005 to Dec. 2005, 32 patients with predominant aortic valve stenosis undergoing DVR in Xinqiao Hospital were included in this study. These patients were randomly divided into four groups with 8 patients in each group： （1） antegrade perfusion group：Cold-blood cardioplegia was delivered antegradely through aortic root, and mitral valve replacement （MVR）was performed. Then cold-blood cardioplegia was delivered antegradely through left and right coronary ostia, and aortic valve replacement （AVR） was performed； （2）retrograde perfusion group：Cold-blood cardioplegia was delivered retrogradely and intermittently through coronary sinus, and DVR was performed； （3）antegrade＋retrograde perfusion group：The route of cold-blood cardioplegic infusion was antegrade during MVR procedure first and then retrograde during AVR procedure；and （4）beating heart group：Oxygenated blood from cardiopulmonary bypass machine was delivered retrogradely and continuously through coronary sinus, and DVR was performed with beating heart. Early clinical outcomes were observed. Serum cardiac troponin I （cTnI） was measured by enzyme-linked immunosorbent assay（ELISA）. Serum creatine kinase-MB （CK-MB） and myocardial lactic acid release rate were measured by Hitachi7150 Automatic Chemistry Analyzer. Myocardial mitochondria malondialdehyde （MDA） level was measured through thiobarbituric acid reagent species analysis. Results All the 32 patients survived their surgery and were discharged successfully. Myocardial lactic acid release rate at 80 min after aortic cross-clamping, serum cTnI and CK-MB on the first postoperative day, myocardial mitochondria MDA levels of beating heart group were 13.59%±6.27%,（1.17±0.25） ng/ml, （56.43±16.50） U/L and（2.18±1.23） nmol/（ng.prot）respectively, all significantly lower than those of retrograde perfusion group ［（33.49%±8.29%, （1.82±0.58 ）ng/ml, （78.31±21.27） U/L （5.07±2.35） nmol/（ng.prot），P＜0.05］ and antegrade＋retrograde perfusion group［20.87%±7.22%, （1.49±0.23） ng/ml,（66.67±19.13） U/L,（4.34±1.73） nmol/（ng.prot），P＜0.05］, but not statistically different from those of antegrade perfusion group ［18.83%±5.97%, （1.41±0.32） ng/ml, （63.21±37.52） U/L, （3.46±1.62） nmol/ （ng.prot），P＞0.05］. Conclusion All the four myocardial protective strategies are effective myocardial protection methods for DVR patients. Continuous retrograde perfusion with beating heart and intermittent antegrade perfusion can provide better myocardial protection, and therefore are preferred for DVR patients. The combination of antegrade and retrograde perfusion is easy to administer and does not negatively influence surgical procedures. Retrograde perfusion is also effective as it takes only a short time.
According to new clinical evidence, the European Society of Cardiology (ESC) and European Association for Cardio-Thoracic Surgery (EACTS) updated and published 2021 ESC/EACTS guidelines for the management of valvular heart disease. This new guideline gives recommendation for clinical assessment, internal treatment and intervention for patients with valvular heart disease with/without comorbidities, which is a globally approbatory reference for clinical practice. This article summarized the updated contents of the new guideline in terms of transcatheter therapy for valvular heart disease.
The 2020 ACC/AHA Guideline for the Management of Patients with Valvular Heart Disease not only updates aortic valve stenosis, mitral regurgitation, prosthetic valves, infective endocarditis and antithrombotic treatment on the basis of the 2017 guidelines update for valvular heart disease, but also involves aortic valve regurgitation, bicuspid aortic valve, mitral stenosis, tricuspid regurgitation, combined valve disease, pregnancy with valvular disease, valve disease complicated with coronary heart disease, valve disease complicated with non-cardiac surgery and the prospect of comprehensive management of valve disease. It covers a wide range of contents, which are introduced in detail and comprehensively. This paper interprets some highlights and core issues, including the top 10 take-home messages, the severity of valvular heart disease, and the updates in the management of aortic valve stenosis, aortic valve regurgitation, bicuspid aortic valve, mitral stenosis and mitral regurgitation.
Technical advances both in cardiac surgery and relating to anesthesia,cardiopulmonary bypass and myocardial protection have significantly improved the prognosis for patients combined with coronary heart disease and heart valve disease. In addition to technology, variable factors that affect operative survival following combined operation include the severity of valvular disease, the number of coronary vessels affected, impairment of left ventricular function and both age and gender differences. In this article, we review the outcome of surgical intervention for heart valve disease combined with coronary heart disease and discuss future prospects in this field.
