ObjectiveTo summarize the individualized selection of surgical treatment strategies and the key points of perioperative management for patients with heart valve disease complicated with severe chronic heart failure.MethodsThe clinical characteristics of 5 male patients with valvular heart disease complicated with severe chronic heart failure (CHF) were analyzed retrospectively from June 2017 to October 2018 in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, with an average age of 60.21 years.ResultsFive patients were given angiotensin receptor and neprilysin inhibitor (ARNI)-based anti-heart failure treatment after admission. The operation mode of these patients was decided to be valve replacement under cardiopulmonary bypass after individualized evaluation of patients’ improving symptoms. Three patients were treated with intra-aortic balloon pump (IABP) and continuous renal replacement therapy (CRRT) early after operation to assist patients in improving cardiac function. Five patients recovered oral anti-heart failure after awakening. All patients were discharged smoothly 2 weeks after operation.ConclusionIndividualized evaluation is needed for the choice of operation timing and mode, standardized preoperative treatment for heart failure, shortening the aortic blocking time during cardiopulmonary bypass, and early application of left ventricular adjuvant drugs or instruments are all important measures to help patients recover smoothly.
Objective To evaluate the left ventricular remodeling after valve replacement for valvular heart disease with giant left ventricle. Methods The clinical material of 92 patients with valvular heart disease and giant left ventricle after valve replacement was retrospectively reviewed. The results of ultrosonic cardial gram（UCG） and the changes of cardiac function before and after operation were compared. Results There was no operative death. The value of left ventricular end-diastolic dimension （LVEDD）, left ventricular end-systolic dimension （LVESD）, left atrial dimension （LAD）, left ventricular ejection fraction （LVEF）, left ventricular fractional shortening （LVFS）, stroke volume （SV） and cardiothoracic ratio in 2 weeks and 2 months after operation were more decreased than those before operation（P〈0. 05）. The value of LVEDD and LAD in 2 months after operation were much more decreased than those in 2 weeks after operation （P〈0. 05）. The cardiac function in early stage after operation was more decreased than that before operation,but the cases of cardiac functional class Ⅱ （38 cases, 41.3% ） in 2 months after operation was significantly more than those before operation （5 cases, 5.4 % ）. Conclusions The early effect of left ventricular remodeling is significant for valvular heart disease with giant left ventricle after valve replacement. The diameter of left ventricle and left atrial are significantly decreased after operation. The protection for cardiac function should be carefully taken in order to prevent the occurrence of complication after operation.
ObjectiveTo investigate clinical outcomes and risk factors of patients with valvular heart disease (VHD) and giant left ventricle undergoing heart valve replacement (HVR).
MethodsClinical data of 144 VHD patients with giant left ventricle who underwent HVR in Union Hospital of Tongji Medical College, Huazhong University of Science and Technology from January 2009 to December 2012 were retrospectively analyzed. There were 116 male and 28 female patients with their age of 15-69 (44.9±11.9) years and disease duration of 57.8±98.3 months (range, 1 month to 40 years). There were 92 patients with rheumatic VHD, 28 patients with degenerative VHD, 15 patients with congenital VHD, and 9 patients with infective endocarditis. A total of 137 patients who were discharged alive were followed up. Risk factors of postoperative mortality, morbidity and late death of VHD patients with giant left ventricle undergoing HVR were analyzed with t-test, chi-square test or Fisher's exact test, and logistic regression analysis. The life-table method was used to calculate long-term survival rate and draw the survival curve.
ResultsMajor postoperative complications included low cardiac output syndrome (LCOS) in 19 patients (13.2%), ventricular arrhythmias in 56 patients (38.9%), prosthetic paravalvular leaks in 7 patients (4.9%), pleural effusion in 33 patients (22.9%), pericardial effusion in 8 patients (5.6%), liver failure in 23 patients (16.0%), and renal failure in 5 patients (3.5%). Seven patients (4.9%) died postoperatively. Logistic univariate analysis showed that advanced-age ( > 50 years), rheumatic VHD, higher preoperative NYHA class (Ⅲ or Ⅳ), long disease duration, poor preoperative left ventricular function[left ventricular ejection fraction (LVEF) < 40%], double valve replace-ment (DVR), other concomitant intracardiac procedures, prolonged cardiopulmonary bypass (CPB) time and aortic cross-clamping time, postoperative LCOS and ventricular arrhythmias were risk factors of early mortality of VHD patients with giant left ventricle undergoing HVR (P < 0.05). Logistic multivariate analysis showed that advanced age ( > 50 years), long disease duration, higher preoperative NYHA class (Ⅳ), poor preoperative left ventricular function (LVEF < 40%), DVR, prolonged CPB time were independent predictors of early mortality (P < 0.05). Logistic multivariate analysis showed that higher preoperative NYHA class (Ⅲ or Ⅳ), other concomitant intracardiac procedures, poor preoperative left ventricular function (LVEF < 50%) were independent predictors of postoperative LCOS (P < 0.05). Higher preoperative NYHA class (Ⅲ or Ⅳ) and preoperative non-sinus rhythm were independent predictors of postoperative ventricular arrhy-thmias (P < 0.05). Within 2 weeks after the operation, left ventricular end-diastolic dimension (LVEDD), left atrial diameter (LAD), LVEF and left ventricular fractional shortening (LVFS) were all significantly reduced compared with preoperative parameters (P < 0.05). Five patients died during follow-up. One-year, 2-year, 3-year and 4-year survival rates were 97.1%, 95.0%, 92.7% and 92.7% respectively. Preoperative LVEF, LVEDD and NYHA were significantly different between patients who died or survived during follow-up.
ConclusionsHVR can produce low postoperative mortality, high long-term survival rates and satisfactory clinical outcomes for VHD patients with giant left ventricle. Advanced age ( > 50 years), long disease duration, higher preoperative NYHA class (Ⅳ), preoperative non-sinus rhythm, poor preoperative left ventricular function (LVEF < 40%), DVR and prolonged operation time may be risk factors of postoperative mortality and morbidity. Poor preoperative left ventricular function and significantly enlarged left ventricle may be risk factors of late death after HVR.
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.
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.
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.
Transcatheter aortic valve replacement (TAVR) is an important treatment for patients with symptomatic severe aortic stenosis. The 2020 updated version of Chinese Expert Consensus on Transcatheter Aortic Valve Replacement was born in the process of Chinese exploration for TAVR. It is of epochal guiding significance for TAVR in China, which has entered a stage of rapid development from the initial stage. Moreover, it further promotes the standardized and healthy development of TAVR in China. The 2020 updated version of Chinese Expert Consensus on Transcatheter Aortic Valve Replacement, based on its 2015 version, has included aortic valve stenosis with a low risk of surgical operation as an indication, made more detailed recommendations on the operating specifications of balloon dilation and valve placement during TAVR, added the antithrombotic program after TAVR, and important opinions on the treatment of coronary atherosclerotic heart disease, renal insufficiency, and emergency TAVR. In this article, we will focus on all these updates to interpret the updated consensus in detail.
Valvular heart disease is one of the common diseases in cardiac surgery. Surgery is the main treatment for valvular heart disease. Cardiac valve replacement surgery corrects the disordered haemodynamics, but the quality life of patients may be affected by multiple factors, such as the disease itself, treatment measures, long-term postoperative anticoagulant and follow-up. This article will provide an overview of the quality of life (origin and definition, evaluation) and the quality of life of patients after cardiac valve replacement (the purpose and significance of quality of life assessment, the quality of life of patients after cardiac valve replacement at different times and different dimensions, influencing factors of the quality of life of patients after surgery), aiming to provide clinical evidence for patients to make decisions before surgery and for clinical medical staff to take intervention measures for patients after surgery.
ObjectiveTo investigate risk factors of in-hospital death of patient after heart valve replacement (HVR) in Xinjiang.
MethodsWe retrospectively analyzed clinical data of 214 patients undergoing HVR in the First Teaching Hospital of Xinjiang Medical university from January 2011 to Month 2014. There were 96 male and 118 female patients with their age of 49.91±13.27 years. According to their postoperative prognosis, all the patients were divided into a death group (21 patients) and a survival group (193 patients). Risk factors of perioperative death were analyzed.
ResultsIn-hospital mortality was 9.81% (21/214). There was statistical difference in preoperative prothrombin time (PT), incidences of left ventricular ejection fraction (LVEF)≤50%, NYHA classⅣ, pulmonary arterial pressure (PAP) > 60 mm Hg, cardiopulmonary bypass time≥2 hours, concomitant coronary artery disease and renal failure between the 2 groups (P < 0.05). Logistic regression analysis showed that shortened preoperative PT, PAP > 60 mm Hg, NYHA classⅣand LVEF≤50% were independently risk factors of in-hospital death after HVR (P < 0.05).
ConclusionsIndependent risk factors of in-hospital death of patients after HVR in Xinjiang include shortened preoperative PT, PAP > 60 mm Hg, NYHA classⅣand LVEF≤50%. Heightened caution is needed for patients with above risk factors to receive HVR after correction of those risk factors.
