ObjectiveTo evaluate the clinical efficacy of tricuspid valve re-operation after left cardiac valve surgery. MethodsWe retrospectively analyzed the clinical data of 23 patients underwent tricuspid valve re-operation in the Affiliated Drum Tower Hospital of Medical School, Nanjing University from January 2009 to November 2014. There were 3 males and 20 females with a mean age 53.48±10.79 years ranging from 34 to 71 years. The average body mass index of the 23 patients was 21.77±2.42 kg/m2. We followed up all the patients in outpatient department or through telephone for 3 months to 5 years. ResultsAll surgeries were operated under cardiopulmonary bypass. There were 15 patients underwent operation through medisternal incision and 8 patients underwent operation through the fourth intercostal incision of right anterolateral side. The mean operation time was 284.35±56.16 minutes and the mean time of cardiopulmonary bypass was 138.61±46.91 minutes. One patient died postoperatively and 2 patients chose to discharge automatically after operation. The other 20 patients recovered and discharged uneventfully. We followed up the patients for 3 months to 5 years. One patient underwent permanent pacemaker therapy for atrioventricular block, 3 patients accepted pharmaceutical therapy for atrial arrhyttmia, 1 patient underwent re-operation for infectious endocarditis of left cardiac artificial valve. and the follow-up conditions of the rest patients were well. Besides, the follow-up data showed that there was a mild regurgitation in 3 patients underwent tricuspid valve plasty. ConclusionTricuspid valve re-operation after left cardiac valve surgery can take multiple surgical pathways and strategies. The clinical effect has been proved and the midterm follow-up condition is well, but we still need the long-term follow-up for the further effect.
Objective Explore the effect of remote ischemic preconditioning (RIPC) on preoperative heart rate variability in patients with heart valves. Methods From January 2022 to July 2022, screening was conducted among 118 patients based on inclusion/exclusion criteria. Fifty-eight patients were excluded, and 60 patients participated in this trial with informed consent and were randomly divided into a RIPC group (n=30) and a control group (n=30). Due to the cancellation of surgery, HRV data was missing. 7 patients in the control group were excluded, and 5 patients in the RIPC group were excluded, 23 patients in the final control group and 25 patients in the RIPC group were included in the analysis. Comparison of relevant indicators of heart rate variability (standard deviation of NN interval (SDNN), standard deviation of mean value of NN interval in every five minutes (SDANN), mean square root of difference between consecutive NN intervals (RMSSD), percentage of adjacent RR interval>50 ms (PNN50), low frequency component (LF), high frequency component (HF) and LF/HF) at 8 hours in the morning on the surgical day between two groups of patients. Results There was no statistical difference in baseline characteristics between the two groups, and there was no significant difference in heart rate variability 24 hours before intervention (P>0.05). After the intervention measures were taken, the comparison of the results of heart rate variability at 8 hours on the day of operation showed that SDNN and SDANN of patients in the RIPC group were higher than those in the control group, with statistical differences (P<0.05). Conclusion RIPC can stabilize the preoperative heart rate variability of patients undergoing cardiac valve surgery.
ObjectiveTo analyze the perioperative outcomes of cardiac valve surgery in patients with asymptomatic SARS-CoV-2 infection. MethodsThe perioperative clinical data of patients receiving heart valve replacement in the Department of Cardiovascular Surgery, the First Affiliated Hospital of University of Science and Technology of China from November 2022 to February 2023 were retrospectively analyzed. According to whether the patients were infected with SARS-CoV-2, they were divided into a non-infected group and an asymptomatic group. The perioperative data of the patients were compared between the two groups, and the effect of asymptomatic infection on the result of heart valve replacement surgery was analyzed. ResultsA total of 66 patients were enrolled including 36 males and 30 females with a mean age of 58.0±11.1 years. There were 51 patients in the non-infected group and 15 patients in the asymtomatic group. There were 2 patients of mitral valve replacement, 20 patients of aortic valve replacement, 1 patient of double valve replacement, 3 patients of aortic valve replacement with tricuspid valvoplasty, 22 patients of mitral valve replacement and tricuspid valvoplasty, 18 patients of double valve replacement and tricuspid valvoplasty. Asymptomatic infected patients received more emergency surgery than uninfected patients (26.7% vs. 0.0%, P<0.01). There was no statistical difference in the duration of extracorporeal circulation, aortic occlusion, mechanical ventilation time after the surgery, ICU stay, postoperative drainage volume, or postoperative complications between the two groups. ConclusionPerioperative results of cardiac valve surgery in patients with asymptomatic SARS-CoV-2 infection and non-infection are almost the same.
