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.
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.
Heart valve disease (HVD) is one of the common cardiovascular diseases. Heart sound is an important physiological signal for diagnosing HVDs. This paper proposed a model based on combination of basic component features and envelope autocorrelation features to detect early HVDs. Initially, heart sound signals lasting 5 minutes were denoised by empirical mode decomposition (EMD) algorithm and segmented. Then the basic component features and envelope autocorrelation features of heart sound segments were extracted to construct heart sound feature set. Then the max-relevance and min-redundancy (MRMR) algorithm was utilized to select the optimal mixed feature subset. Finally, decision tree, support vector machine (SVM) and k-nearest neighbor (KNN) classifiers were trained to detect the early HVDs from the normal heart sounds and obtained the best accuracy of 99.9% in clinical database. Normal valve, abnormal semilunar valve and abnormal atrioventricular valve heart sounds were classified and the best accuracy was 99.8%. Moreover, normal valve, single-valve abnormal and multi-valve abnormal heart sounds were classified and the best accuracy was 98.2%. In public database, this method also obtained the good overall accuracy. The result demonstrated this proposed method had important value for the clinical diagnosis of early HVDs.
ObjectiveTo investigate the clinical effect of Maze Ⅳ in the treatment of elderly patients with valvular heart disease and persistent atrial fibrillation (AF).MethodsWe retrospectively analyzed the clinical data of 78 elderly patients with cardiac valve disease combined with persistent AF in our hospital from 2017 to 2018. The patients were allocated to two groups including a trial group (n=37) and a control group (n=41). There were 21 males and 16 females aged 61 to 74 (65.2±2.5) years in the trial group. There were 23 males and 18 females aged 62 to 76 (64.8±3.3) years in the control group. The clinical effects of the two groups were compared.ResultsThere was no statistical difference in baseline data between the two groups (P>0.05). The aortic occlusion time, extracorporeal circulation time, and operation time of the trial group were longer than those of the control group with statistical differences (P<0.05). There was no statistical difference in postoperative ventilator assistance time, complication rate, mortality, ICU retention time, perioperative drainage, red blood cell transfusion volume, or length of hospital stay between the two groups (P>0.05). At the time of discharge, postoperaive 1-month, 3-month, 6-month, and 12-month, the maintenance rates of sinus rhythm in the control group were statistically different from those of the trial group (P<0.05). Compared with the control group, left atrial diameter, left ventricular end diastolic diameter and the decrease of pulmonary artery systolic blood pressure were statistically different (P<0.05).ConclusionMaze Ⅳ is safe and effective in the treatment of elderly patients with valvular heart disease and persistent AF, which is conducive to the recovery and maintenance of sinus rhythm, and is beneficial to the remodeling of the left atrium and left ventricle and the reduction of pulmonary systolic blood pressure with improvement of life quality of the patients.
As the aging proceeds worldwide, aging lung transplantation recipients have been increased dramatically. Aging population with end-stage lung diseases also have comorbidities, such as cardiovascular disease, which may impact the prognosis of lung transplantation. Recent researches on lung transplantation have explored the characteristics of aging recipients, strategy selection on transplantation and cardiovascular disease management, as well as risk factors for post-transplantation complications and death. However, researches on lung transplantation recipients with cardiac valve disease are just in the initial stage. With the advancement of transcatheter technique, more patients will be benefited. We summarized the advancement in this field and took an outlook for future clinical researches.

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 investigate the impact of red blood cell suspension infusion across various perioperative periods on patients with valvular heart disease. Methods The patients with valvular heart disease admitted to Tianjin Chest Hospital from 2018 to 2020 were selected. Based on the timing of perioperative red cell suspension infusion, patients were categorized into three groups: a group 1 receiving intraoperative red cell suspension infusion, a group 2 receiving red cell suspension infusion within 24 hours after entering the ICU, and a group 3 receiving red cell suspension infusion at both time points. The laboratory results, perioperative blood component infusion volume, and other relevant parameters were retrospectively analyzed. After propensity score matching, the differences in different variables among the three groups were compared. Results After propensity score matching, 102 patients were enrolled, including 52 males and 50 females, with an average age of (61.74±10.58) years. There were 34 patients in each group. The preoperative hemoglobin (Hb) value of the group 2 was significantly higher than that of the group 1 and the group 3, and the amount of red cell suspension and autoblood transfusion was the lowest (P<0.05). In the group 1, Hb was the highest after surgery, Hb was the highest within 24 hours after surgery. HCT was the highest within 24 hours after surgery (P<0.05). The group 1 had the lowest plasma, platelet and cryoprecipitate infusion volumes, and the shortest cardiopulmonary bypass time, aortic occlusion time, postoperative ICU stay and hospital stay, and the least blood loss, total drainage volume (P<0.05). The difference between postoperative Hb and preoperative △Hb1 was significantly increased in the group 1 (P<0.05). Conclusion The intraoperative infusion of suspended red blood cells in patients with heart valves can be used to indicate to clinicians that patients have a better prognosis at discharge, review and follow-up.
