RESUMO
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 < .001; ACC time: 65 ± 19.94 min vs. 50 ± 24.90 min, respectively, p < .001). postoperative hospital stay time (5.11 ± 2.48 days vs. 5.90 ± 6.27 days, p = .488) and chest drainage (139.86 ± 111.71 ml vs. 196.13 ± 147.34 ml, p = .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.

AIM: The aim of this study was to investigate the feasibility, safety, and clinical effect of modified unicaval drainage for thoracoscopic reoperative isolated tricuspid valve repair, compared with conventional bicaval drainage. METHODS: A total of 45 consecutive cases of patients who underwent thoracoscopic reoperative isolated tricuspid valve repair on beating-heart were enrolled and divided into two groups according to the different venous drainage (Group A: modified unicaval drainage, Group B: conventional bicaval drainage). A retrospective analysis of perioperative data and clinical outcomes were performed and all the surviving cases were followed up. Re-evaluation of echocardiography and electrocardiogram was performed prior to discharge, and at first month, sixth month, and every year follow-up. RESULTS: The overall postoperative 30-day mortality was 4.5% in Group A and 8.7% in Group B. The postoperative tricuspid valve regurgitation grade of both groups decreased significantly from preoperative regurgitation grade, p < 0.001, without intergroup significant difference, p = 0.815. Follow-up duration ranged from 6 to 38 months, there was one death at 24 months in Group A, and another at 9 months in Group B, respectively. Nobody from both groups experienced reintervention for residual tricuspid regurgitation. No significant difference could be identified about the incidence of postoperative morbidities and follow-up adverse events. CONCLUSION: Both strategies of caval venous drainage can provide satisfactory exposure for thoracoscopic reoperative isolated tricuspid valve repair and equivalent favorable postoperative outcome. And the modified unicaval drainage group may even preserve the anesthetic time and decrease the risk of iatrogenic jugular injury, achieving a more simplified procedure with better cosmetic outcome.

OBJECTIVE: To observe the efficacy of hybrid balloon valvuloplasty for the treatment of low-body weight infants with severe congenital valvular aortic stenosis (AS). METHODS: Five infants with severe congenital valvular aortic stenosis underwent the hybrid balloon aortic valvuloplasty through median sternotomy in the hybrid operating room. The mean age was (40.2 ± 7.0) days, weight was (4.48 ± 0.75) kg. The patients were followed up by echocardiography for 9 - 13 months post procedure. RESULTS: Operation was successful in all 5 patients and they were discharged from hospital uneventfully. The gradient pressure decreased significantly from (98.8 ± 9.0) mm Hg (1 mm Hg = 0.133 kPa) to (13.8 ± 3.3) mm Hg (P < 0.05) post operation. There was no moderate or severe aortic insufficiency. All patients were alive, the gradient pressures was (18.8 ± 2.5) mm Hg and there was no moderate or severe aortic insufficiency during follow-up [9 - 13 (11.0 ± 1.4) months]. CONCLUSION: The hybrid balloon aortic valvuloplasty is an effective option for the low-body weight infants with severe congenital valvular aortic stenosis.

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.

BACKGROUND: To evaluate the safety and efficacy of femoral artery cannulation as an alternative to axillary artery cannulation, we retrospectively compared outcomes between patients with axillary or femoral artery cannulation during open aortic arch repair for type A aortic dissection (TAAD). METHODS: Between January 2014 and January 2019, 646 patients underwent open aortic arch repair with circulatory arrest for TAAD using antegrade selective cerebral perfusion (SACP) and were divided into two groups according to the site of arterial cannulation: an axillary artery group (axillary group, n=558) or a femoral artery group (femoral group, n=88). The axillary artery was considered as the primary cannulation site, and the femoral artery was used as an alternative when axillary artery cannulation was deemed unsuitable or had failed. Propensity score matching was performed to correct baseline differences. RESULTS: After propensity score matching, the patients' characteristics were comparable between groups (n=85 in each). The incidence of in-hospital mortality (10.6% vs. 14.1%; P=0.642) and stroke (3.5% vs. 5.9%; P=0.720) were comparable between the axillary and femoral groups. The incidence of newly required dialysis was lower in the femoral group, but the difference was not statistically significant (34.1% vs. 20.0%; P=0.050). Other outcomes and major adverse events were comparable. CONCLUSIONS: Femoral artery cannulation produced similar perioperative outcomes to axillary cannulation after open arch repair for TAAD. The femoral artery can be used as a safe and effective alternative to the axillary artery for arterial cannulation in TAAD patients undergoing open arch repair.
RESUMO
OBJECTIVE: This study was performed to evaluate the association of preoperative anxiety with inflammatory indicators and postoperative complications in patients undergoing scheduled aortic valve replacement surgery. METHODS: A prospective cohort study was performed. The Hamilton Anxiety Scale was used to assess preoperative anxiety. The serum white blood cell (WBC) count and concentrations of C-reactive protein, interleukin (IL)-6, and IL-8 were measured 1 day preoperatively and 3 and 7 days postoperatively. Postoperative complications were also recorded. RESULTS: Seventy-three patients were included. The incidence of preoperative anxiety was 30.1% (22/73). The payment source was the only independent risk factor for preoperative anxiety. The incidence of postoperative complications was lowest in the mild anxiety group. The WBC count 3 days postoperatively was significantly lower in the mild than moderate-severe anxiety group. The IL-8 concentration 1 day preoperatively was highest in the no anxiety group. CONCLUSIONS: Mild preoperative anxiety might help to improve clinical outcomes. However, further investigations with more patients are warranted. Patients with different degrees of anxiety may have different levels of inflammatory cytokines.

BACKGROUND: 18F-FDG PET/CT is a key molecular imaging modality to noninvasively assess and differentiate benign and malignant cardiac tumors. However, few benign cardiac tumors can be characterized by increased 18F-FDG uptake, which makes differential diagnosis difficult. This study sought to retrospectively evaluate whether combined 18F-FDG PET/CT with thoracic contrast-enhanced CT (CECT) helps in assessing primary cardiac tumors in adult patients, compared with CECT or PET/CT alone. METHODS: Forty-six consecutive patients who were diagnosed as primary cardiac tumors were enrolled. All patients underwent 18F-FDG PET/CT followed by thoracic CECT before biopsy or surgery. Visual qualitative interpretation and quantitative analysis were performed, and diagnostic performance was evaluated. RESULTS: More than half (16/29) of benign tumors exhibited with mild 18F-FDG uptake. There were significant differences in 18F-FDG uptake and the degree of absolute enhancement between benign and malignant tumors (P < 0.001). The combination of two modalities improved the specificity from 79 to 93%, the positive predictive value from 73 to 89%, and the accuracy of diagnosis from 85 to 93%. There were significant differences between PET/CT alone or thoracic CECT alone and combined modalities (P = 0.034 and P = 0.026, respectively). The combination with the optimal SUVmax cutoff value generated 94% sensitivity, 100% specificity, 97% negative predictive values, 100% positive predictive values, and 98% accuracy rates. CONCLUSIONS: Combining 18F-FDG PET/C with thoracic CECT significantly improved specificity and accuracy compared to CECT or PET/CT alone in detecting tumors. This combination of diagnostic imaging is effective in differentiating malignant from benign masses.
