An 82-year-old man was taken to a local clinic following the occurrence of syncope. Chest roentgenography and computed tomography (CT) findings led to a suspicion of a ruptured aortic aneurysm, and the patient was immediately transferred to our hospital. Upon admission, his consciousness was clear and blood pressure was 74/47mmHg. Enhanced chest CT images demonstrated pericardial effusion and a saccular aneurysm with a maximum diameter of 5cm, which was associated with a thrombus in the distal aortic arch. An emergency operation was performed under a diagnosis of a ruptured distal aortic arch aneurysm and hemorrhagic cardiac tamponade. During the procedure, a hole was found in the lesser curvature of the aneurysm, which had directly ruptured into the pericardial space, and a graft replacement of the aortic arch was performed using selective cerebral perfusion. The patient was discharged 19 days after surgery without any postoperative complications.

A 69-year-old man complained of abdominal pain with inflammatory reaction. Abdominal aortic aneurysm (AAA) with a left main trunk lesion was diagnosed and he successfully underwent Y-graft replacement of the abdominal aorta and coronary artery bypass grafting. Finally AAA was classified as “inflammatory” by histopathological findings. We present this case of “inflammatory AAA” associated with coronary artery disease, and discuss it with a review of literatures.

Staged arterial switch operation without homologous blood transfusion was successfully performed in 5 patients weighing 4.1-11.0kg (double outlet right ventricle: 2 cases, transposition of great arteries: 3 cases). The postoperative hemodynamics and respiratory status were uneventful in all patients (initial central venous pressure after ICU admission: 9.0-14.5cmH2O, mean 12.5cmH2O, duration of intubation: 3.5-18.0h, mean 7.8h). Autologous blood donation immediately after induction of anesthesia and minimization of bypass circuit were effective methods for open heart surgery without homologous blood transfusion, particularly in staged arterial switch operation requiring prolonged cardiopulmonary bypass.

A 78-year-old woman who had undergone an axillobifemoral artery bypass with a prosthetic graft for Leriche syndrome presented 1 month later with cough and fever. A clinical examination revealed obvious redness in the right groin. Routine laboratory tests uncovered inflammation and methicillin-sensitive-Staphylococcus aureus was cultured from blood samples. Mitral valve vegetations were identified by echocardiography, and after a diagnosis of infective endocarditis, specific intravenous antibiotics were immediately administered. One month later, CT revealed a large pseudoaneurysm of the posterior left ventricular wall that had not been present at the time of admission. Transesophageal echocardiography and magnetic resonance imaging showed an aneurysmal cavity arising from the wall just below the posterior mitral valve leaflet. The patient agreed to undergo cardiac surgery due to the high likelihood that the pseudoaneurysm would rupture. The mitral annulus and leaflet were normal at surgery. We resected the posterior leaflet, closed the cavity using a Xenomedica patch, and reconstructed the leaflet. We did not remove the pseudoaneurysm using an extracardiac approach because the likelihood of damaging the coronary arteries and the coronary sinus was quite high. The postoperative course was uneventful. At follow-up 1 year later, the patient was afebrile and both CT and echocardiography showed that the cavity was completely filled by the thrombus. The imaging findings were useful in determining the surgical approach.

Background : This study was performed to evaluate surgical outcomes after cardiovascular surgery (including urgent surgery) in patients 85 or older. Methods : A retrospective analysis was performed on 39 patients (mean age, 86.3 years ; age range, 85-90 years) who underwent total arch replacement (n=4), ascending aorta replacement (n=4), descending aorta replacement (n=1), aortic valve replacement (AVR ; n=13), mitral valve replacement or valvuloplasty (n=3), coronary artery bypass grafting (CABG ; n=9), CABG+AVR (n=4), tumor resection (n=1) between June 2008 and December 2012 at Dokkyo Medical University Hospital. Results : Six hospital deaths occurred. One patient died due to bleeding from a ruptured descending thoracic aortic aneurysm, and another patient died due to gastrointestinal perforation from non-occlusive mesenteric ischemia (NOMI) after urgent AVR. The other deaths were related to various complications, including lung cancer, cholecystitis, myocardial infarction, and Takotsubo cardiomyopathy, during the postoperative period. Overall 30-day mortality was 2.6%, hospital mortality was 12.8%, duration of hospital stay after surgery was 41.3 days, duration of intensive care unit (ICU) stay was 3.8 days and ventilator time was 49.1 h. Twenty patients underwent elective surgery, and 19 patients underwent urgent surgery. The two groups had similar preoperative characteristics, except for the number of patients with aortic disease. No significant difference was evident in hospital mortality (26.3% vs. 5%, p=0.065) or 30-day mortality (0% vs. 5.3%, p=0.3) when comparing the two groups. However, the duration of hospital stay (58.9 days vs. 27.5 days, p=0.049), ICU stay (6.74 days vs. 1.05 days, p=0.002) and ventilator time (89.9 h vs. 8.2 h, p=0.006) was significantly longer in the urgent surgery group than in the elective surgery group. Fourteen patients (70%) in the elective surgery group and four patients (21.1%) in the urgent surgery group were able to be discharged from the hospital to their homes within 30 days after surgery. These data demonstrated that cardiovascular surgery in patients 85 years of age or older was associated with satisfactory outcomes, and outcomes associated with elective surgery were even better than those associated with urgent surgery. Conclusions : Therefore, advanced age does not represent a contraindication of conventional cardiovascular surgery. Rather, the decision for surgery should take the patient's preoperative condition, the severity of concurrent medical disease, the wishes of the patient, and the predicted functional outcomes into account.

Purpose: The present study was conducted to elucidate the gap in awareness of experience of care management and the actual work of being responsible for this field by spotlighting on the attributes of of case managers and who are in charge of care management of terminal cancer patients at home.
Methods: Anonymous individual style questionnaire investigation was conducted against a target of 443 care managers.
Results: 70.3% had experience being in charge of terminal cancer patients and there was a significant difference in that this was found in those of more than 5 years of experience and among those of full timer status. As for experience in regard to those with or without experience being in charge by basic type of job, there was not much significant difference.
As for awareness regarding being in charge of terminal cancer patients, those who felt “I want to avoid it”, remained in 25% and found more in non-fulltimers (P<0.05). As for those who thought that “health care providers are more suited to be in charge”, this was found in 70% of health care providers and 40% in welfare related individuls (P<0.05) and a significant difference was noted. As for awareness of “should not depend on specific profession and should be done fairly among professions and which was found in 80% of those who have less than 5 years among care support specialist profession and hence compared to those with more than 5 years, it was many, and a significant gap was found. Regarding need of education and training about care management of terminal cancer patients, 95% agreed there is.
Conclusion: Approximately 70% of all had experience with terminal cancer patients and particularly, among those with over 5 years as care support specialist, it became clear that full timers were in charge. However, about awareness of being in charge of care management, it became clear that there was an positive attitude toward who takes in charge without being restricting to specific individuals and not selecting by number of years of experince as care managers nor by basic job types. Therefore, it can be concluded that opportunity for education and training about care management of terminal cancer patients and consolidating education environment for self training is important.

Right sided infective endocarditis (RSIE) is uncommon. Patients are traditionally treated with antibiotics alone, and indications for operation are not clearly established. A 23-years-old man who developed fever and general fatigue was referred to our hospital on the suspicion of RSIE. A ventricular septal defect (VSD) and untreated dental caries had been previously diagnosed. Transthoracic echocardiography revealed vegetation on the tricuspid valve and severe regurgitation. The tricuspid valve was repaired ; the anterosuperior leaflet was partially resected and repaired with fresh autologous pericardium and the use of synthetic chordae. Recurrence of infection and tricuspid valve regurgitation were not observed for 1 year after this operation.

Purpose : Recently, the Japanese government has promoted reform of working practices. The working environment of medical professionals was no exception. In the present study, we investigated the current working environment and issues of cardiovascular surgeons, who are supposed to be working in one of the most demanding circumstances in Japan. Methods : In December 2018, the Japanese Society for Cardiovascular Surgery (JSCVS) sent a questionnaire to all JSCVS members via the internet to obtain basic data on the working environment including working hours, working items, income, and the issues to be solved for cardiovascular surgeons in Japan. Results : The JSCVS received responses from 634 cardiovascular surgeons (response rate 17%, 589 males/38 females). Respondents were primarily mid-career surgeons in their age of 40 s and 50 s. Four hundred seventy-three respondents (75.5%) and 176 respondents (28.2%) answered that they worked an average of 60 and 80 h a week, respectively. In addition, 249 respondents (40.4%) reported receiving no allowance for on-call work during off hours, after midnight, or on a holiday, while 345 respondents (56.6%) reported receiving no allowance for emergency surgery during off hours, after midnight, or on a holiday. Conclusion : Over 75% of cardiovascular surgeons reported being overworked without receiving an appropriate amount of income. Along with the reform of working style being made for the Japanese people, improving the working environment of cardiovascular surgeons is also an urgent matter to maintain healthcare for cardiovascular disease. Facilitating understanding of the issue by the Japanese people is of the utmost importance for the JSCVS.

Patient: A 74-year-old man. Previous history: Total arch replacement for thoracic aortic aneurysm at 72 years old. History of current condition: The patient presented at a local otolaryngology clinic complaining of hoarseness of the voice. Left vocal cord paralysis was present, and as he had previously undergone thoracic vascular graft replacement, he was referred to our department. Further investigation with computed tomography (CT) revealed air in the mediastinum, and he was admitted for treatment of mediastinitis. Post-admission course: Upper gastrointestinal endoscopy revealed esophageal ulceration. After antibiotic treatment, thoracic subtotal esophagectomy via right thoracotomy, esophagostomy, and gastrostomy were performed on admission day 39. Vascular graft infection was also suspected, and antibiotic treatment was therefore continued. As some improvement in inflammatory response was evident, antibiotic treatment was discontinued and the patient's condition was monitored, but fever developed on day 107, and CT again revealed air in the mediastinum. Bronchoscopy revealed a broncho-mediastinal fistula in the left main bronchus. On day 110, repeated total arch replacement using a vascular graft, omentoplasty, and left main bronchus repair were performed via left thoracotomy. Esophageal reconstruction was left for later surgery, but follow-up CT on day 160 again revealed air in the mediastinum. Bronchoscopy was performed the same day and revealed a broncho-mediastinal fistula in the left main bronchus, located on distally from the previous fistula. This fistula was surgically closed on day 173. The subsequent course was favorable, and antethoracic esophageal reconstruction by jejunal elevation was performed on day 233. The patient was able to start eating on day 244, and was discharged in an improved condition on day 250.

The case is that of a 90-years-old man. A previous doctor performed abdominal graft replacement for an abdominal aortic aneurysm 5 years earlier and continued outpatient CT follow-up. Follow-up CT showed the right aortic arch and dilation of the thoracic aortic aneurysm, and the patient was referred to our hospital. Contrast-enhanced CT showed an aortic arch aneurysm ; the aneurysm diameter was 62 mm in major axis and 60 mm in minor axis, which was judged to be suitable for surgery. It was a rare right-sided aortic arch with no congenital heart malformation and no situs inversus. Endovascular treatment was considered because he was 90 years old and very elderly, but there were concerns about the risk of embolism, irregular manipulation and central landing. For the surgical method, we selected total arch replacement using a frozen elephant trunk technique. We succeeded in avoiding serious complications by selecting an appropriate treatment method through careful evaluation.
