Mid-term outcomes of right subaxillary approach versus median sternotomy incision for ventricular septal defect with patent ductus arteriosus.

BACKGROUND: This study aimed to evaluate and compare two surgical approaches to repair ventricular septal defect (VSD) with patent ductus arteriosus (PDA) and to explore the patients' health-related quality of life (HRQoL). METHODS: We conducted a retrospective study of all patients who had surgical repair of VSD and PDA between 2013 and 2015 using the right subaxillary approach (group A) or the median sternotomy incision (group B). The outcomes of both techniques were compared. Paediatric QoL Inventory 4.0 scale was applied to assess patients' HRQoL in the 6th postoperative year. Multiple linear regression analysis was performed to explore factors associated with higher HRQoL scores. RESULTS: A total of 128 patients were included (group A, n = 70 and group B, n = 58). Patients in group A were older and heavier than patients in group B. In group B, the diameters of VSD and PDA were larger and the pulmonary artery pressures were higher than those in group A (p < 0.001). No mortality occurred on a mean follow-up of 8.3 ± 1.2 years. Patients in group A had higher HRQoL scores than those in group B in terms of emotional and social functioning dimensions. The right subaxillary approach (OR: 3.56; 95% CI 1.65-5.46), higher parents' education level (OR: 1.62; 95% CI 0.65-2.31), and better family economic status (OR: 1.48; 95% CI 0.79-2.45) were associated with higher HRQoL scores. CONCLUSIONS: Younger and smaller patients receiving median sternotomy incisions due to large defects and pulmonary hypertension had lower HRQoL scores. The right subaxillary approach, higher parents' education level, and better family economic status were associated with higher HRQoL scores.

Impact of minimally invasive mitral valve surgery on sexual dysfunction in male patients.

BACKGROUND: Sexual dysfunction after cardiac surgery can seriously affect patients' quality of life, but the impact of cardiac surgery on sexual function has long been neglected. Compared with conventional cardiac surgery, minimally invasive cardiac surgery has the advantages of aesthetic appearance and no disruption of the sternal structure, which can greatly improve the patient's quality of life. However, studies focusing on the effects of minimally invasive mitral valve surgery (MIMVS) on sexual function have not been reported. The objective of this research was to investigate the effects of totally endoscopic mitral valve surgery on health-related quality of life and sexual function in male patients and to provide possible recommendations. METHODS: Patients who underwent median sternotomy or totally endoscopic mitral valve surgery at our institution from January 2019 to December 2020 were selected using an electronic medical record system. Data were collected by questionnaires, including the MOS 36-item short-form health survey and the International Erectile Function Questionnaire. RESULTS: There were 156 male patients who participated in our study. Of these, 112 patients completed all questionnaires. Forty-five patients (40.18%) developed postoperative sexual dysfunction, including 15 patients (29.41%) in the MIMVS group and 30 patients (49.18%) in the conventional MVS group, indicating that the incidence of sexual dysfunction could be reduced by MIMVS and that the MIMVS group scored better on the International Erectile Function Questionnaire (P < 0.05). On the evaluation of health-related quality of life, the MIMVS group scored better than the MVS group on the mental health and bodily pain subscales of the MOS 36-item short-form health survey. In addition, our study showed that postoperative sexual dysfunction was associated with physical functioning and mental health. CONCLUSIONS: In our study, totally endoscopic mitral valve surgery had less adverse effects on sexual function in male patients than conventional mitral valve surgery. In terms of health-related quality of life, totally endoscopic mitral valve surgery was superior to conventional surgery. Patients who opt for totally endoscopic mitral valve surgery may have a more satisfying and healthier sexual life than those who undergo conventional mitral valve surgery.

Quality of life: modified triple-branched stent graft implantation versus frozen elephant trunk technique.

OBJECTIVE: To compare the effects of modified triple-branched stent implantation and frozen elephant trunk technique on the quality of life (QoL) of acute Stanford Type A aortic dissection (AAAD) patients at different follow-up times. METHODS: Data from 175 AAAD survivors was collected which were divided into two groups according to different surgical techniques: (group A): modified triple-branched stent graft implantation; (group B): frozen elephant trunk. The SF-36 were used to assess the QoL at discharge (AD), the third postoperative month (POM3), and the twelfth postoperative month (POM12). RESULTS: (1) The total scores at each time of both groups showed lower than the normal level; Group A scored higher than group B at some time points in terms of some items (role physical, role emotion and mental health; all P = 0.000), and some items at POM3 or POM12 scored higher than at discharge (role physical, social function; both P = 0.000). (2) There were less patients with heavy self-perceived burden in group A than group B at discharge (P = 0.032) and patients with heavy self-perceived burden decreased over time. (3) Young postoperative AAD patients (P = 0.002) in group B (P = 0.005) with heavy self-perceived burden (P = 0.000), acute renal failure (P = 0.008), long LOS (P = 0.026) and blood loss (> 1000 mL/24 h) (P = 0.039) seemed to get a worse QoL. CONCLUSION: The impact on QoL of the modified triple-branched stent graft implantation technique seemed to be better than those of frozen elephant trunk surgery in role physical, role emotion and mental health.

A Modified Approach with Caval Transection for Supracardiac Total Anomalous Pulmonary Venous Connection: Comparison Between Conventional and Sutureless Surgery in 173 Patients.

The efficacy of primary sutureless repair for supracardiac total anomalous pulmonary venous connection (TAPVC) needs to be confirmed. This study aimed to compare the long-term outcomes between the conventional surgery and the sutureless technique with a modified approach in superior TAPVC. Between January 2008 and December 2018, 173 patients with supracardiac TAPVC underwent surgery either with the conventional procedure (n = 130) or the sutureless repair (n = 43). Multivariate analysis and competing-risk analysis were used to identify risk factors for early death and postoperative pulmonary venous obstruction (PVO), respectively. Among 173 patients who underwent repair of supracardiac TAPVC, 46 (28%) had preoperative PVO, and 22 (12.7%) had postoperative PVO. The sutureless group had a lower postoperative PVO rate compared with the conventional group (p = 0.027). The risk factors for death were age ≤ 28 days [odds ratio (OR), 11.56; 95% confidence interval (CI) 1.33-100.47, p = 0.015], weight ≤ 3 kg (OR 9.57; 95% CI 1.58-58.09, p = 0.009), emergency operation (OR 19.24; 95% CI 3.18-116.35, p = 0.002), cardiopulmonary bypass time (OR 2.16; 95% CI 1.36-3.43, p = 0.003), cross-clamp time (OR 1.73; 95% CI 1.20-2.50, p = 0.022), and duration of ventilation (OR 1.11; 95% CI 1.02-1.21, p = 0.027). Age ≤ 28 days [Hazard Ratio (HR) 1.92; 95% CI 1.92-11.02, p < 0.001] and preoperative PVO (HR 41.70; 95% CI 8.15-213.5, p < 0.001) were associated with postoperative PVO. The sutureless repair is a reliable technique for supracardiac TAPVC. Age ≤ 28 days is associated with 30-day mortality and postoperative PVO.

Telmisartan reduces atrial arrhythmia susceptibility through the regulation of RAS-ERK and PI3K-Akt-eNOS pathways in spontaneously hypertensive rats.

Telmisartan is an angiotensin II receptor blocker that displays unique PPAR-γ modulating activity. PPAR-γ agonists have been shown to decrease susceptibility to atrial fibrillation through their antioxidant and antiapoptotic effects. The aim of this study was to determine whether telmisartan would have a greater effect on susceptibility to atrial arrhythmia in a hypertensive rat model than valsartan, which is a traditional angiotensin II receptor blocker. In this study, spontaneously hypertensive rats were treated with 10 mg·(kg body mass)(-1)·d(-1) telmisartan (TEL group), 10 mg·(kg body mass)(-1)·d(-1) valsartan (VAL group), or vehicle (saline; SHR group) for 4 weeks. Age-matched Wistar-Kyoto rats (WKY) were used as normotensive controls. After 4 weeks of treatment, we performed echocardiographic assessment, electrophysiological analysis, histological evaluation, and Western blot analysis. Telmisartan decreased systolic blood pressure to a similar extent as valsartan. Relative to the WKY controls, atrial arrhythmia susceptibility was significantly increased in the SHR group, and was significantly decreased by both telmisartan and valsartan, albeit to a greater extent with telmisartan. Arrhythmogenic atrial remodeling, including enlargement of the left atrium, myocyte hypertrophy, interstitial fibrosis, and myocyte apoptosis, was observed in the SHR group, and was accompanied by activated RAS-ERK signaling and suppressed PI3K-Akt-eNOS signaling. The results suggest that telmisartan reduced susceptibility to atrial arrhythmia to a greater extent than valsartan, ameliorated atrial remodeling, and reversed imbalances in the RAS-ERK and PI3K-Akt-eNOS pathways.
