    Objectives: To determine the outcomes and prognostic factors associated with pulmonary resection of pulmonary pleomorphic carcinoma (PPC).

    Methods: During 2008–2017, 17 patients underwent pulmonary resection for primary PPC at the Saitama Cancer Center, Japan. We investigated clinicopathological characteristics and outcomes of these cases. Overall survival (OS) and disease-free survival (DFS) rates were determined using Kaplan–Meier method and compared using log-rank test. Univariate analysis was performed to identify prognostic factors.

    Results: The 5-year OS and DFS rates were 27.2% and 51.0%, respectively. The median follow-up period was 30.8±24.9 (3.6–92.8) months after pulmonary resections. Patients with disease-free interval (DFI) <1 year of resection had poorer prognosis than those without (p = 0.001). Patients with N2 status and adenocarcinoma components had significantly poorer disease-free prognosis than their counterparts (p = 0.021 and p = 0.019, respectively). Univariate analysis revealed that DFI <1 year was an unfavorable prognostic factor for OS (p = 0.005); N2 pathological status and presence of adenocarcinoma components were unfavorable prognostic factors for DFS (p = 0.038 and p = 0.036, respectively).

    Conclusion: PPC patients with an adenocarcinoma component and N2 pathological status may have an earlier relapse and poorer prognosis than their counterparts. Further assessment of cases may help clarify the predictors of PPC.

    Objectives: To evaluate plombage surgery for hemoptysis control in pulmonary aspergilloma in high-risk patients.

    Methods: This study was carried out on 75 pulmonary aspergilloma patients presenting with hemoptysis that underwent a plombage surgery for approximately 7 years (November 2011–September 2018) at Pham Ngoc Thach Hospital. They revisited the hospital 6 months after plombage surgery and considered plombage removal. The group whose plombage was removed was compared with that whose plombage was retained 6 and 24 months after surgery.

    Results: Hemoptysis reduced significantly after surgery. Hemoptysis ceased in 91.67% of the patients and diminished in 8.33% of the patients 6 months after surgery. Similarly, hemoptysis ceased in 87.32% of the patients and diminished in 12.68% of the patients 24 months after surgery. Body mass index (BMI) index, Karnofsky score, and forced expiratory volume in one second (FEV1) increased. Plombage surgery was performed with operative time of 129.5 ± 36.6 min, blood loss during operation of 250.7 ± 163.1 mL, and the number of table tennis balls of 4.22 ± 2.02. No deaths related to plombage surgery were recorded. Plombage was removed in 29 cases because of patients’ requirements (89.8%), infection (6.8%), and pain (3.4%). There were no patient developing complications after the treatment and there were no statistically significant differences between the two groups.

    Conclusions: Plombage surgery is safe and effective for hemoptysis control in pulmonary aspergilloma. To minimize the risk of long-term complications, surgeons should remove the plombage 6 months after the initial operation.

    Objective: To investigate the effect of treprostinil on the early postoperative prognosis of patients with severe left heart valvular disease combined with severe pulmonary hypertension (PAH).

    Methods: A retrospective study including 55 patients with severe left heart valvular disease combined with severe PAH who underwent left heart valve replacement in our hospital between January 2019 and May 2019 was conducted. Patients were divided into two groups (treprostinil group and control group), and the clinical data of patients in the two groups were compared and analyzed.

    Results: Compared with the preoperative status, the mean postoperative pulmonary artery pressure (mPAP) in both groups was significantly lower. Compared with the control group, the treprostinil group had a significantly lower mPAP. Moreover, the postoperative mechanical ventilation time, intensive care unit (ICU) stay, and hospital stay of the treprostinil group were significantly shorter than those of the control group. There were no serious drug-related side effects in either group.

    Conclusions: Treprostinil can improve the early postoperative prognosis of patients with severe left heart valvular disease combined with severe PAH undergoing prosthetic valve replacement.

    Purpose: Deep sternal wound infection (DSWI) and mediastinitis are devastating complications after median sternotomy. Previous studies demonstrated an effective prevention of sternal wound infection (SWI) using an external sternal corset in high-risk cardiac surgery patients. The aim of this study is to assess the preventive effect of the Stern-E-Fix corset in high-risk poststernotomy female patients.

    Methods: A total of 145 high-risk female patients undergoing cardiac surgery through median sternotomy were retrospectively analyzed. Patients were divided into group A (n = 71), who received the Stern-E-Fix corset (Fendel & Keuchen GmbH, Aachen, Germany), and group B (n = 74), who received the elastic thorax bandage (SanThorax) postoperatively for 6 weeks. The mean follow-up period was 12 weeks.

    Results: Incidence of SWI was 7% in group A vs. 17.6% in group B (p = 0.025). One patient presented with DSWI in group A vs. seven patients in group B (p = 0.063). No patient developed mediastinitis in group A vs. four patients in group B (p = 0.121). In all, 4.2% of group A patients required operative wound therapy vs. 16.2% of group B patients (p = 0.026). The length of hospital stay was significantly longer in group B (p = 0.006).

    Conclusion: Using an external supportive sternal corset (Stern-E-Fix) yields a significantly better and effective prevention against development of sternal dehiscence, DSWI, and mediastinitis in high-risk poststernotomy female patients.

    Purpose: To evaluate clinical outcomes of customized mitral valve plasty (MVP) for the treatment of functional mitral regurgitation (FMR) with a low ejection fraction (EF) and to determine which preoperative factors affected the clinical outcome.

    Methods and Results: MVP was adjusted according to the degree of left ventricle (LV) remodeling. We performed mitral annuloplasty (MAP) alone in 14 patients and added subvalvular procedures (SVPs) in 22 patients at a high risk of recurrent MR. During follow-up, reverse LV remodeling was obtained and the 3-year and 5-year non-recurrence rates of MR grade ≥2 were 94% and 89%, respectively. Two patients died during their hospital stay, and four more patients died of cardiac causes during follow-up. The 3-year and 5-year rates of freedom from cardiac-related mortality were 86% and 81%, respectively; no significant difference was observed between the two treatment groups. Right ventricular fractional area change (RVFAC) was a significant predictor of cardiac mortality. Patients with an RVFAC of <26% had significantly poorer cardiac-related mortality (71% at 3 years) than those with an RVFAC of ≥26% (95% at 3 years).

    Conclusion: Customized MVP provided durable mitral competence and reverse LV remodeling. Preoperative RV function was associated with cardiac-related mortality.

    Purpose: This study was conducted to identify predictors of respiratory failure after open repair of descending thoracic aortic aneurysm (DTAA), and to identify any relationship between respiratory failure and long-term survival.

    Methods: A total of 75 patients undergoing elective open DTAA repair at the Shiga University of Medical Science Hospital were included in the study. Univariate and multivariate logistic regression analyses were performed to assess the odds ratios for incident postoperative respiratory failure after open DTAA repair. Survival over time was estimated by the Kaplan–Meier method.

    Results: Respiratory failure, defined as ventilation dependence for longer than 48 hours, occurred in 11 patients (14.7%). Independent predictors of respiratory failure after DTAA included prolonged operation time and reduced preoperative forced expiratory volume in 1 second/forced vital capacity × 100 (FEV1%). In-hospital mortality was higher (p = 0.020) among patients with respiratory failure (18.2% of those who suffered respiratory failure) than among those without (0%). The survival rates at 8 years were significantly lower (p = 0.010) in the respiratory failure group (at 44.2%) than in the group without respiratory failure (at 89.0%).

    Conclusion: Lower FEV1% and longer operation time were risk factors of postoperative respiratory failure after open repair of DTAA, which in turn is associated with significantly reduced long-term survival.

    Purpose: Left atrial appendage (LAA) isolation is an effective surgical treatment for decreasing thromboembolic risk. We sought to evaluate the short-term effect of minimally invasive surgery with LAA excision on left atrial dynamic and endocrine function in atrial fibrillation (AF) patients.

    Methods: A total of 52 patients with paroxysmal AF undergoing minimally invasive surgery with LAA excision in Anzhen Hospital from October 2012 to June 2014 were enrolled in the study. The natriuretic peptide plasma level was determined by enzyme-linked immunosorbent assay (ELISA), and left atrial dynamic function was measured preprocedure by real-time three-dimensional echocardiography and postprocedure after 7 days and 3 months.

    Results: With the exception of six recurrences, 88.5% (46/52) of the patients were prospectively followed over 3 months in terms of their sinus rhythm postprocedure. No severe operative complications or embolism events occurred within those 3 months. Echocardiography showed a 3–6% decrease in left atrial volume postprocedure, and dynamic function was largely restored by 3 months. There was no significant change in natriuretic peptide levels, although a slight decrease was detected 7 days postprocedure, which gradually recovered by 3 months (P = 0.350).

    Conclusions: There are no significant differences in left atrial dynamics and natriuretic peptide secretion in AF patients after minimally invasive surgery with LAA excision.

    Purpose: To identify differences in surgical outcomes between patients with transforming growth factor-beta receptor (TGFBR) 1 and TGFBR2 mutations in Loeys-Dietz syndrome (LDS).

    Methods: In all, 22 LDS patients between 1998 and 2015 were divided into the two groups: TGFBR1 (n = 11) and TGFBR2 mutation (n = 11).

    Results: The freedom from aortic reoperation was similar between the two groups (p = 0.19, log-rank). In the subanalysis, the freedom from aortic reoperation was lower in female patients with TGFBR2 mutations (n = 6) than in other patients (p = 0.08). The freedom from aortic dissection (AD) after the initial surgery was also lower in female patients with TGFBR2 mutation than in other patients (p = 0.025). All patients with TGFBR2 mutations revealed grade III cystic medial necrosis (CMN), whereas 67% of patients with TGFBR1 mutations showed CMN (p = 0.033) and only one patient had grade III (p <0.001).

    Conclusion: LDS patients with TGFBR2 mutations had higher grade of CMN than those of TGFBR1 mutations. In particular, in female patients with TGFBR2 mutations, AD after the initial surgery and reoperation were more frequent than those of other LDS patients.

    An increasing number of children with congenital heart disease are surviving into adulthood and subsequently developing end-stage heart failure. Two example populations are adults who have been previously operated on for congenitally corrected transposition of the great arteries (CCTGA) and transposition of the great arteries (TGA). Implantation of a continuous flow left ventricular assist device (CF-LVAD) in these patients can present unusual anatomical and physiologic challenges. In this report, we describe outcomes of CF-LVAD implantation in three such patients. These cases demonstrate the feasibility of implanting a CF-LVAD in patients who have undergone surgery for CCTGA and/or TGA.

    Spontaneous rupture of the thoracic aorta is rare. We present a 76-year-old man who developed spontaneous rupture of the aortic arch associated with massive periaortic hematoma and hypovolemic shock. Because the site of rupture could not be identified, emergency hybrid endovascular aortic repair to shield a long segment of the aorta was performed according to the extent and density of periaortic hematoma on axial CT scans. His blood pressure improved just after deployment of the endograft. Rapid diagnosis by CT and prompt control of aortic hemorrhage by endografting salvaged this patient. Three-dimensional (3D) volume-rendered CT images are useful for identifying the site of aortic rupture, but may not be available in an emergency.
