OBJECTIVE: We retrospectively investigated the possibility that the 6-min walk test (6MWT) could predict surgical outcomes in lung cancer patients with decreased predicted postoperative (ppo) lung function. METHODS: Patients were enrolled based on their preoperative spirometry: <60% of the ppo forced expiratory volume in 1 s (FEV1.0) or < 60% of the ppo lung carbon monoxide diffusion capacity (DLco). Morbidity, oxygen inhalation required > 10 days, home oxygen therapy (HOT) requirement, unexpected readmission within 90 days, and 90-day mortality were included as surgical outcomes...

BACKGROUND: We assessed the mitral annular motion after mitral valve repair with the Sorin Memo 3D® (Sorin Group Italia S.r.L., Saluggia, Italy), which is a unique complete semirigid annuloplasty ring intended to restore the systolic profile of the mitral annulus while adapting to the physiologic dynamism of the annulus, using transesophageal real-time three-dimensional echocardiography. METHODS: 17 patients (12 male; mean age 60.4 ± 14.9 years) who underwent mitral annuloplasty using the Memo 3D ring were investigated...

We herein reported a rare case of an occult fallopian tube carcinoma first detected from the diaphragm metastasis. An 83-year-old woman who had a 30-mm tumor on the right diaphragm underwent radical resection. Pathologically, the tumor was diagnosed as a high-grade serous adenocarcinoma, suggesting metastasis from the pelvic visceral carcinoma. Although the primary site could not be detected by imaging examinations, laparoscopy revealed multiple peritoneal disseminations; therefore, total hysterectomy was performed...

Controversy still surrounds the optimal biological valve substitute for aortic valve replacement. In light of the current literature, we review advantages and optimal indications of stentless compared to stented aortic bio-prostheses. Recent meta-analyses, prospective randomized controlled trials and retrospective studies comparing the most frequently used stentless and stented aortic bio-prostheses were analyzed. In the present review, the types and implantation techniques of the bio-prosthesis that are seldom taken into account by most studies and reviews were integrated in the interpretation of the relevant reports...

During open aortic arch repair, there is an interruption of cerebral perfusion and to prevent neurological sequelae, the hypothermic circulatory arrest has been established to provide sufficient brain protection coupled with adjuncts including retrograde and antegrade cerebral perfusion. To date, brain protection during open aortic arch repair is a contested topic as to which provides superior brain protection with little evidence existing to suggest supremacy of one modality over the other. This article reviews current literature reflecting on key and emerging studies in brain protection and their associated outcomes in patients undergoing open aortic arch surgery...

OBJECTIVE: Presenting our experience of direct perfusion of the carotid artery in patients with brain malperfusion secondary to acute aortic dissection. PATIENTS: Among 381 patients who underwent aortic repair for acute type A aortic dissection from October 1999 to August 2017, brain malperfusion was recognized in 50 patients. Nine patients had direct perfusion of the right carotid artery in patients with brain malperfusion secondary to acute aortic dissection. Age at surgery was 65...

We reported a surgical case of methotrexate-associated lymphomatoid granuloma. A 69-year-old female had been treated with methotrexate for rheumatoid arthritis for 35 months. The patient underwent partial resection of the right upper pulmonary lobe for lung cancer when she was 67 years old. A nodule was detected in the left lung field on a chest radiograph performed during the postoperative follow-up period. Computed tomography revealed a 28-mm nodule in the lower left pulmonary lobe. A transbronchial biopsy examination did not lead to a diagnosis...

REVIEW

Video-assisted thoracoscopic surgery (VATS) has gradually been implemented in thoracic surgery, and the VATS approach has now been extended to technically challenging procedures, such as segmentectomy. The definition of VATS segmentectomy is changing over time, and the repertoire of segmentectomy is getting wider with increasing reports on atypical segmentectomy. VATS segmentectomy bears surgical, oncological, and technical advantages; however, there are still areas of controversy, particularly regarding oncological outcomes...

REVIEW
Norihisa Shigemura
For the patients with progressively decompensating acute or acute-on-chronic respiratory failure, the first-choice treatment remains as mechanical ventilation. Despite the consistent value of mechanical ventilation, the majority of lung specialists are aware of its limitations, in particular for the patients with advanced lung failure, and inherent drawbacks that augment disease progression. More recently, the concept of allowing the lungs to 'rest and recover' has been supported by quite a few clinical studies...

Approximately one-third of patients with infective endocarditis require surgical treatment, but the ideal procedure that prevents infection ensures long durability and maintains quality of life remains unclear. A 21-year-old man who was diagnosed with aortic active infective endocarditis was referred to our hospital for surgical treatment. Echocardiography showed bicuspid aortic valve, severe aortic regurgitation, a large vegetation, and a paravalvular abscess. We planned to perform elective surgical treatment after antibiotic therapy; however, progression to heart failure required urgent operation...

In Kawasaki disease (KD), giant coronary aneurysms in the proximal segments of the coronary arteries have long been among the serious complications associated with acute myocardial infarction. To treat myocardial ischemia in children, Kitamura et al. first performed coronary artery bypass grafting in a pediatric patient using an autologous saphenous vein. In the early 1980s, they began to use the internal thoracic artery (ITA) as a bypass graft to the left anterior descending artery, which later was proven to improve long-term life expectancy with its favorable long-term patency, as well as growth potential...

Thoracic aortic aneurysm (TAA) is an increasingly recognized condition that is often diagnosed incidentally. This review discusses ten of the most relevant epidemiological and clinical secrets of this disease; (1) the difference in pathogenesis between ascending and descending TAAs. TAAs at these two sites act as different diseases, which is related to the different embryologic origins of the ascending and descending aorta. (2) The familial pattern and genetics of thoracic aneurysms. Syndromic TAAs only explain 5% of the pattern of inheritance...

Bioprosthesis are commonly used in the elderly population. Structural valve deterioration affects the long-term durability. We report an early deterioration of a Mitroflow valve caused by ring deformation and prosthetic leaflet rupture. The 69-years-old patient underwent successful redo surgery with excision of the bioprosthesis and placement of a mechanical valve.

OBJECTIVES: Although strict blood glucose control during cardiovascular surgery is essential to avoid postoperative complications, the various changes in glucose levels that occur during surgery have not been investigated in detail. In this study, we continuously monitored blood glucose changes during aortic surgery using the STG-55Ⓡ artificial endocrine pancreas (Nikkiso Inc., Tokyo). METHODS: Between December 2015 and 2016, we performed continuous blood glucose monitoring in 22 patients (14 men and 8 women, 72 ± 11 years old), who required hypothermic circulatory arrest during an ascending/aortic arch surgery, at the Jichi Medical University Hospital...

Catheter ablation provides effective results for sustained monomorphic ventricular tachycardia (VT), but the presence of mural thrombus including dense calcification occasionally causes unfavorable outcomes. The case of a 67-year-old man in whom sustained monomorphic VT, which was resistant to endocardial radiofrequency ablation, in the presence of mural thrombus including dense calcification after coronary artery bypass grafting was successfully treated by left ventricular reconstruction with cryoablation is reported...

The management of cardiopulmonary bypass for pediatric cardiac surgery is more challenging than that in adults due to the smaller size, immaturity, and complexity of the anatomy in children. Despite major improvements in cardiopulmonary bypass, there remain many subjects of debate. This review article discusses the physiology of cardiopulmonary bypass for pediatric and congenital heart surgery, including topics related to hemodilution, hypothermia, acid-base strategies, inflammatory response, and myocardial protection...

Several cases of traumatic ventricular septal defect (VSD) have been reported. However, traumatic VSD complicated by tricuspid rupture is rare. We report a case of traumatic VSD with tricuspid rupture who required repeated repair of both conditions. A 69-year-old man was transferred to our hospital for emergent surgical repair of traumatic VSD and tricuspid rupture. Although emergent repair was performed, a new left-to-right shunt and moderate tricuspid regurgitation appeared during his postoperative course...
