Hemodynamic predictors of negative false lumen remodeling after frozen elephant trunk for acute aortic dissection
ConclusionsThe range between peak and nadir flow rates may serve as a hemodynamic predictor of negative false lumen remodeling, enabling further treatment for patients at risk of expansion in the downstream aorta. (Source: General Thoracic and Cardiovascular Surgery)

A comparative study of robot-assisted thoracoscopic surgery and conventional approaches for short-term outcomes of anatomical segmentectomy
ConclusionsRATS segmentectomy is proposed to be useful. It was suggested that RATS segmentectomy may be useful with better perioperative results than the conventional approach. Further studies on oncological long-term outcomes and cost –benefit comparisons are needed. (Source: General Thoracic and Cardiovascular Surgery)

Rough-zone suspension with mitral valve replacement for ventricular functional mitral regurgitation
AbstractChordal preservation is recommended in mitral valve replacement for functional mitral regurgitation to preserve left ventricular function. In contrast, papillary muscle suspension toward the anterior mitral annulus can induce left ventricular reverse remodeling after mitral valve replacement for functional mitral regurgitation. However, the extent of suspension depends on the surgeon ’s experience. Therefore, we developed a new concept of chordal preservation, called rough-zone suspension, which not only spares the subvalvular structure but also suspends the papillary muscles toward the annulus. This procedure is...

Internal circular suture annuloplasty for aortic valve repair
We report our technique of internal circular suture annuloplasty. We used a continuous horizontal mattress suture of a single thick expanded polytetrafluoroethylene suture (CV-3). We put 4 stitches per sinus, so the suture was below the cusp attachment line at the nadirs and passed through the interleaflet triangle at the upper aorto-ventricular junction level. The suture was reinforced with pericardial pledgets on both sides of each commissure. We used this technique in 12 patients. The diameter of aorto-ventricular junction was reduced from 25  ± 2 mm to 22 ± 1 mm (n = 11) and was 22 ± 1 mm at the l...

Preoperative physical activity is associated with prognosis in patients with esophageal cancer undergoing thoracoscopic –laparoscopic esophagectomy after neoadjuvant chemotherapy
ConclusionsThis study demonstrated that a single preoperative physiotherapy session during neoadjuvant chemotherapy improves physical function, and preoperative physical activity is significantly associated with prognosis. (Source: General Thoracic and Cardiovascular Surgery)

Adjustable external Dacron annuloplasty in aortic valve repair
AbstractIn aortic valve repair, whilst performing a Yacoub remodelling operation, the external annuloplasty of the aortic ring plays a very important role. Here we present an adjustable external Dacron annuloplasty as an additional tool, in very selected cases, that can help surgeons to further improve their immediate results thus influencing the long-term ones.

Real-world safety and effectiveness of inhaled nitric oxide therapy for pulmonary hypertension during the perioperative period of cardiac surgery: a post-marketing study of 2817 patients in Japan
ConclusionsPerioperative INOflo treatment was a safe and effective strategy to improve hemodynamics and oxygenation in patients with pulmonary hypertension during cardiac surgery. These data support the use of INOflo for this indication in Japanese clinical practice. (Source: General Thoracic and Cardiovascular Surgery)

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)

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)
