ObjectiveTo investigate effect of cardiac function and tricuspid regurgitation (TR) degree of concomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent mitral valve replacement (MVR), and provide an objective basis for clinical decision about concomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent MVR. MethodsA total of 36 patients who underwent MVR from April to October 2013 in Department of Cardiovascular Surgery, West China Hospital, Sichuan University were enrolled in this study. Preoperative echocardiography showed mild TR and tricuspid valve annular end-diastolic dimension (TVAEDD)/body surface area (BSA)>21 mm/m2. All the 36 patients were randomly divided into a tricuspid annuloplasty group (TAPG group, n=18, including 7 males and 11 females) and a no tricuspid annuloplasty group (NTAPG group, n=18, including 6 males and 12 females). One week and 6 months postoperative echocardiography were recorded. ResultsThere were no statistical differences in age, gender, heart rate, body surface area, preoperative cardiac function (NYHA), left atrium dimension (LAD), left ventricular dimension (LVD), maximal long-axis of RA (RAmla), mid-RA minor distance (RAmmd), right ventricle dimension (RVD2), left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS) between the two groups (P>0.05). Six-months postoperative left atrial-ventricular diameter significantly reduced than that before surgery in the two groups (P<0.05). In the TAPG group, six-months postoperative right ventricle dimension (RVD1), right ventricular wall thickness (RVWT), tricuspid valve annular end-diastolic dimension (TVAEDD), tricuspid valve annular end-systolic dimension (TVAESD) significantly decreased, while percent shorting of tricuspid valve annulus (PSTVA) did not change significantly (P>0.05), TR degree improved significantly (P<0.05), right ventricular fractional area change (RVFAC) and right ventricular ejection fraction (RVEF) significantly increased (P<0.05). In the NTAPG group, compared with preoperative data, six-months postoperative RVD1, RVWT significantly increased, TVAEDD, TVAESD, PSTVA did not change significantly (P>0.05), RVEF reduced significantly (P<0.05), RVFAC increased significantly but less than that in the TAPG group at the same period, constituent ratio of TR changed significantly (P<0.05), but postoperative moderate or more TR were recorded in 6 patients. ConclusionConcomitant tricuspid annuloplasty for patients with tricuspid valve annulus dilation and mild TR underwent mitral valve replacement (MVR) can help to decrease RVD1, RVWT, TVAEDD and TVAESD, improve the constituent ratio of TR, and increase RVFAC and RVEF.
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.
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.
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.
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.
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.
Surgical Therapy for Valve Diseases Combined with Coronary Heart Diseases in Patients Over or Below 70 Years Old YU Lei, GU Tianxiang, SHI Enyi, XIU Zongyi, FANG Qin, ZHANG Yuhai. (Department of Cardiac Surgery, The No. 1 Hospital of China Medical University, Shenyang 110001, P.R. China)Corresponding author: GU Tianxiang, Email: cmugtx@sina.comAbstract： Objective To summarize the experiences of valve replacement combined with coronary artery bypass grafting (CABG) in senile patients by comparing clinical outcomes of valve diseases combined with coronary heart diseases in patients over or below 70 years old. Methods We retrospectively analyzed the clinical data of 49 patients who received valve replacement combined with CABG in our department from May 1999 to December 2007. Based on the age, the patients were divided into ≥70 years group (17 cases) with its patients at or above 70 years old and lt;70 years group (32 cases) with its patients younger than 70. The percentage of chronic obstructive pulmonary diseases (COPD) before surgery in ≥70 years group was higher than that in lt;70 years group(Plt;0.05). No significant difference was found in the other relevant factors between the two groups. The clinical index of patients in the two groups were compared and analyzed. Results There were significant differences between the two groups in such factors as the percentage of biovalve use (82.4% vs. 12.5%, χ2=23.311, P=0.000), the time of mechanic ventilation (34.5±29.3 h vs. 18.0±16.1 h, t=-2.542,P=0.014), the time of ICU stay (4.4±1.5 d vs. 3.3±0.7 d, t=-3.522, P=0.001), the time of hospital stay (21.4±7.7 d vs. 18.1±1.8 d, t=-2.319, P=0.025), the percentage of IABP use (29.4% vs. 6.3%, χ2=4.862, P=0.037), the percentage of pulmonary function failure (35.3% vs. 6.3%, χ2=6.859, P=0.009), the percentage of acute renal failure (23.5% vs. 3.1%, χ2=5.051, P=0.025), and the percentage of cerebrovascular accident (11.8% vs. 0.0%, χ2=3.933, P=0.048). There was no significant difference between the two groups in factors like the anastomosis of distal graft (2.5±3.1 vs. 2.4±14, t=0.301, P=0.758), the time of aortic occlusion (89.3±25.4 min vs. 88.5±31.0 min, t=0.108,P=0.913), the time of cardiopulmonary bypass (144.6±44.8 min vs. 138.3±52.9 min, t=0.164, P=0.871) and the mortality (5.9% vs. 6.3%, χ2=0.002,P=0.959). The perioperative myocardial infarction rate was zero in both groups. ≥70 years group patients were followed up for 2 months to 9 years with only 1 case missing. One patient who had undergone mechanic valve replacement died of cerebral hemorrhage 1.5 years after operation. Two died of heart failure and lung cancer 3 months and 6 years after operation respectively. For all the others, the cardiac function was at class Ⅰ to Ⅱ and their life quality was significantly improved. The follow up time of lt;70 years group was 1 month to 6 years and 5 cases were missing. Four patients who had undergone mechanic valve replacement died of complications in relation to anticoagulation treatment. One died of severe low cardiac output. Another died of traffic accident. Conclusion Surgery operation and effective perioperative treatment are key elements in improving surgery successful rate and decreasing mortality in patients with valve and coronary artery diseases. Valve replacement combined with CABG is safe for patients older than 70 years old.
