Objectives To compare early and long-term outcomes of redo-isolated tricuspid surgery (RITS) after left-sided valve surgery. Methods We retrospectively reviewed 173 patients who underwent RITS for severe tricuspid regurgitation after previous left-sided valve surgery from January 1999 to December 2019. Patients were divided into two groups: RITS by median sternotomy (m-RITS; n = 78) and totally endoscopic approach (e-RITS; n = 95). Perioperative outcomes and follow-up results were analyzed. Results There were 19 (11%) in-hospital deaths (14.1% in m-RITS and 8.4% in e-RITS, p = .234) that decreased from 16.7% (1999-2014) to 6.9% (2015-2019) (p = .044). Tricuspid valve replacement (odds ratio [OR] = 4.989, 95% confidence interval [CI]: 1.133-29.790, p = .041) and NYHA function class IV (OR = 9.611, 95% CI: 2.102-43.954, p = .004) were independent risk factors for in-hospital mortality. The overall 1-, 5-, 10-, and 15-year survival rates were 97.2% (95% CI: 94.5%-99.9%), 80.3% (95% CI: 71.7%-88.9%), 59.2% (95% CI: 43.5%-75.5%), and 49.3% (95% CI: 27.2%-71.4%), respectively. Conclusion Patients undergoing RITS carry a high risk of early mortality. There was no significant difference in early mortality or long-term survival between the endoscopy and median sternotomy, whereas the endoscopy approach was associated with shorter intensive care unit stays and fewer reoperations. Repair resulted in lower surgical mortality than replacement with acceptable residual tricuspid regurgitation.

Objectives To explore the safety and efficacy of total thoracoscopic repair of ventricular septal defects (VSD). We compared clinical outcomes of VSD via a total thoracoscopic approach with those of mini‐sternotomy. Methods We retrospectively reviewed clinical data from patients with VSD from 2012 to January 2019. According to the surgical pattern, they were divided into two groups: the total thoracoscopic surgery group (36 patients, 27 females, aged 29 ± 9.52 years), and a mini‐sternotomy group (31 patients, 12 females, aged 28 ± 8.67 years). Results There were no deaths in either group. In the thoracoscopic group, cardiopulmonary bypass (CPB) time and aortic cross‐clamping (ACC) time were significantly longer than those of the mini‐sternotomy group (CPB time: 112 ± 23.16 min vs. 78 ± 37.90 min, respectively, p

Background The strategy of isolated tricuspid valve surgery has undergone innovations in recent years. This study aimed to summarize our experience using an endoscopic approach to repeat isolated tricuspid valve surgery (RITS) after left-sided valve replacement (LSVR). Methods From June 2013 to May 2019, 79 patients underwent endoscopic RITS after LSVR at our institution. Patients were divided into the tricuspid valvuloplasty (TVP) group (N.=49) and the tricuspid valve replacement (TVR) group (N.=30); perioperative outcomes and follow-up results were compared. Results There were seven postoperative deaths (8.9%). In-hospital mortality was higher in the TVR group than in the TVP group, although this difference was not statistically significant (13.3% vs. 6.1%, P=0.417). More patients experienced residual moderate-to-severe tricuspid regurgitation (TR) at discharge in the TVP group than in the TVR group (26.7% vs. 0%, P=0.003). Five patients died from heart, and multiorgan failure during follow-up; the overall 3- and 5-year survival rates were 93.8% [95% confidence interval (CI): (87.1-99.9%)] and 85.3% (95% CI: 73.3-99.2%), respectively, and no significant differences were found between the two groups (P=0.103). The overall rates of the 3- and 5-year freedom from severe recurrent TR were 93.2% (95% CI: 85.9-99.9%) and 89.0% (78.7-99.9%), respectively, and no significant difference was found between groups (P=0.176). Conclusions Repeat isolated tricuspid valve surgery after left-sided valve replacement is associated with adverse perioperative outcomes. Endoscopic access offers an alternative approach for RITS after LSVR with acceptable results. TVP results in lower surgical mortality than TVR while carrying a higher risk of residual moderate-to-severe TR.

Objectives: To explore the safety and efficacy of total thoracoscopic repair of ventricular septal defects (VSD). We compared clinical outcomes of VSD via a total thoracoscopic approach with those of mini-sternotomy. Methods: We retrospectively reviewed clinical data from patients with VSD from 2012 to January 2019. According to the surgical pattern, they were divided into two groups: the total thoracoscopic surgery group (36 patients, 27 females, aged 29.08 ± 9.52 years), and a mini-sternotomy group (31 patients, 12 females, aged 28.39 ± 8.67 years). Results: There were no deaths in either group. In the thoracoscopic group, cardiopulmonary bypass (CPB) time and aortic cross-clamping (ACC) time were significantly longer than those of the mini-sternotomy group (CPB time: 111.78 ± 23.16 min vs 77.58 ± 37.90 min, respectively, p < 0.001; ACC time: 111.78 ± 23.16 min vs 77.58 ± 37.90 min, respectively, p < 0.001). Tracheal intubation time (6.42 ± 3.85 hours vs 28.55 ± 123.18 hours, p = 0.325), intensive care unit (ICU) stay time (20.47 ± 9.52 hours vs 49.65 ± 163.72 hours, p = 0.330), postoperative hospital stay time (5.11 ± 2.48 days vs 5.90 ± 6.27 days, p = 0.488) and chest drainage (139.86 ± 111.71 ml vs 196.13 ± 147.34 ml, p = 0.081) tended to be lower in the thoracoscopy group, although there was no significant difference. No residual shunt or tricuspid regurgitation was found at follow-up. Conclusions: Total thoracoscopic repair is safe and effective in patients with VSD, with or without tricuspid regurgitation.
