Safety and efficacy of aortic valvuloplasty for de novo aortic insufficiency in patients with a left-ventricular assist device
ConclusionsAVP using Park ’s stitch was safe. It is critical to carefully observe the aortic valve during AVP surgery to ensure that AVP is appropriate. (Source: General Thoracic and Cardiovascular Surgery)

Learning curve of robotic surgery for lung cancer: analysis for two surgeons during the COVID-19 pandemic
ConclusionThis study described our first experience with the Da Vinci Robotic System in our department. The curves had a similar shape which shows the learning curve of robotic surgery using the CUSUM method is reproducible. Furthermore, our results showed that the learning curve may improve after the programme starts in the department when the different team elements are all trained.

Cardioprotective effect of St. Thomas ’ Hospital No. 2 solution against age-related changes in aquaporin-7-deficient mice
ConclusionsThe present study revealed the cardio-protective efficacy of STH2 in an experimental model of isolated AQP7-KO young and aged murine hearts. Further, STH2 preserved intra-myocardial ATP during ischemia with Krebs –Henseleit buffer perfusion in the Langendorff setting. (Source: General Thoracic and Cardiovascular Surgery)

Predictors of residual simultaneous multiple ground-glass nodule progression after dominant lesion resection
ConclusionsIf the resected dominant lesion or the residual second dominant GGN exhibits high-risk factors, the second dominant GGN should be meticulously observed. (Source: General Thoracic and Cardiovascular Surgery)

Risk factor analysis for aortic dissection after aortic valve replacement in patients with tricuspid aortic valve
ConclusionAortic regurgitation combined with ascending aortic dilatation at aortic valve replacement could be a significant risk factor for late aortic dissection. (Source: General Thoracic and Cardiovascular Surgery)

Myostatin expression in lung cancer induces sarcopenia and promotes cancer progression
ConclusionSarcopenia may be induced by myostatin secreted by lung cancer cells. Moreover, myostatin may promote TAM migration into the tumor microenvironment, leading to advance lung cancer. As a result, patients with high myostatin expression had poor prognosis. (Source: General Thoracic and Cardiovascular Surgery)

Reconstruction of right ventricular outflow tract with severe calcification: lantern procedure
AbstractRight ventricular outflow tract reconstruction is repeatedly required after the Rastelli procedure. However, standard right ventricular outflow tract reconstruction using direct anastomosis on the posterior right ventricular outflow tract wall is unfeasible in cases with severe calcification. Herein, we present a novel technique called the “lantern procedure,” which can fix the prosthetic pulmonary valve without anastomosis to the calcified right ventricular outflow tract wall.

Sutureless repair with Hydrofit ® and bovine pericardial patch for oozing-type postinfarction cardiac rupture
AbstractLeft ventricular free wall rupture is a fatal complication of myocardial infarction for which infarctectomy and reconstruction of the left ventricle using a prosthetic patch under cardiopulmonary bypass are performed. However, these surgical treatments remain challenging. Left ventricular free wall rupture secondary to acute myocardial infarction was diagnosed in an 86-year-old man. We performed sutureless repair of the left ventricular free wall rupture without cardiopulmonary bypass. During the operation, a pre-gluing bovine pericardial patch with Hydrofit® was placed twice on the ruptured site and manually pres...

Uniportal video-assisted thoracoscopic surgery for pediatric cases
AbstractThe potential advantages of video-assisted thoracoscopic surgery (VATS) for children include better cosmetic outcomes and reduced risk of postoperative musculoskeletal deformities. The uniportal approach is expected to promote minimally invasive surgery and help reduce the incidence of postoperative musculoskeletal deformities. Uniportal VATS was performed safely in three children (mean age of 23.3  months) with congenital pulmonary airway malformation or extralobar pulmonary sequestration. Our findings suggest that minimally invasive lobectomy may be achieved through uniportal VATS in children. (Source: General T...

Watch-and-wait strategy for selected patients with type A intramural hematoma
ConclusionsThe early and midterm outcomes with the initial watch-and-wait strategy in patients with type A intramural hematoma with a maximum aortic diameter of  ≤ 50 mm, pain score of ≤ 3/10, and no ulcer-like projection in the ascending aorta were favorable with no aorta-related death.

Blood flow analysis with computational fluid dynamics in the left atrium after left atrial plication: a prospective study
ConclusionsBlood flow stagnation was noted in the LAA and enlarged LA. CFD analysis revealed that LAP for the enlarged LA improved blood flow stagnation more than the virtual LAAR alone.Clinical trial registry numberUMIN000049923. (Source: General Thoracic and Cardiovascular Surgery)

Outcomes of ascending aorta and partial arch replacement with entry resection for DeBakey type I acute aortic dissection
ConclusionsEarly and late outcomes in the Non-TAR group were satisfactory compared to those in the TAR group. Entry resection with graft replacement remains a standard approach in DIAAD repair. (Source: General Thoracic and Cardiovascular Surgery)

Console and bedside surgeon fused robot-assisted thoracic surgery
AbstractIn the last decade, even thoracic surgery has seen an increase in the use of robotic surgical systems, and robot-assisted thoracic surgery (RATS) is considered one of the main issues. While RATS is associated with solo manipulative freedom and high-definition optical systems, several disadvantages, such as the lack of tactile sensation and difficult learning curves for the whole team, have been raised. Therefore, to overcome these issues, we developed a ‘fusion surgery’ approach combining a robotic procedure with manual maneuvers, where the table surgeon retracts the lung and staples the pulmonary vasculature a...

Surgical treatment of primary cardiac tumors in children
ConclusionsPrimary cardiac tumors in children are mostly benign. Surgery is effective, but the timing of surgery depends on the patient's condition. (Source: General Thoracic and Cardiovascular Surgery)
