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.

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.
Preoperative evaluation is crucial for heart valvular surgery. This article discusses some issues that need to be emphasized: the impact of hypertension on the severity of aortic valve lesions, and how to improve the accuracy of clinical assessment; the identification of functional tricuspid regurgitation, in order to choose the appropriate surgical technique; the need for right ventricular function testing, and the use of risk scoring models, to better grasp surgical timing and indications and improve efficacy; and the importance of evaluating atrial mitral and/or tricuspid regurgitation complications in chronic atrial fibrillation, and making rational choices for interventional and surgical treatment.
Objective To investigate and evaluate the safety and effectiveness of the Chimney technique in mitral valve reoperation. Methods The clinical data of mitral valve reoperation patients who underwent Chimney surgery in Wuhan Asia Heart Hospital from 2019 to 2021 were retrospectively analyzed. Results A total of 26 patients were collected, including 7 males and 19 females, aged 27-67 (53.46±11.18) years. All patients had previous mitral valve surgery, including 23 mitral valve replacements and 3 mitral valve repairs. All patients received Chimney technique using the ideal artificial sized mitral valve, and 1 patient died of neurological complications in hospital. The cardiopulmonary bypass time and the aortic cross-clamping time were 231.11±77.05 min and 148.50±52.70 min, respectively. The mean diameter of the implanted mitral valve prosthesis was 29.08±0.68 mm, which was statistically different from pre-replacement valve prosthesis size of 26.69±0.77 mm (P＜0.001). The mean transvalvular pressure gradient of the prosthetic mitral valve measured on postoperative echocardiography was 14.77±5.34 mm Hg, which was statistically different from preoperative value of 20.92±9.83 mm Hg (P=0.005). Conclusion The Chimney technique is safe and effective for reoperation in patients with small mitral annuli, which can not only reduce the risk of reoperation, but also obtain larger prosthetic valve implants with good hemodynamic characteristics and clinical outcomes.
Objective To compare the effect of monopolar and bipolar radiofrequency ablation in patients with atrial fibrillation and concomitant rheumatic heart disease. Methods The clinical data of 261 patients who underwent valve replacement and radiofrequency Maze Ⅲ procedure in Shanghai First People's Hospital from 2010 to 2015 were retrospectively analyzed. According to the radiofrequency ablation system, patients were assigned to a monopolar radiofrequency ablation group (n=209, 129 males, 80 females, aged 59.6±9.7 years) and a bipolar radiofrequency ablation group (n=52, 36 males, 16 females, aged 58.6±11.2 years). After procedures, clinical factors such as patients' basic information, perioperative complication and mortality, the elimination rate of atrial fibrillation were measured. Results There was no statistic difference in perioperative morbidity and mortality between two groups. The ablation time of the monopolar radiofrequency ablation group was longer than that of the bipolar group (29.7±3.3 minvs. 22.3±7.8 min,P=0.035). Postoperative diameter of left atrium was reduced in both groups. Compared with the monopolar radiofrequency ablation group, bipolar group had a better elimination rate of atrial fibrillation at three months and one year follow-up (82.0%vs. 66.3%,P=0.037; 80.0%vs. 59.6%,P=0.008). Conclusion Valve replacement combined with radiofrequency Maze Ⅲ procedure is safe and efficient. Compared with monopolar radiofrequency ablation, bipolar radiofrequency ablation has advantage on elimination rate of atrial fibrillation, ablation time and cardiopulmonary bypass time.
