We describe a case of cardiac surgery for a patient with CD36 deficiency. A 56-year old man had progressive dyspnea on effort for 1 year. On admission, echocardiography revealed severe aortic valve regurgitation. He required medical treatment for heart failure, and subsequently elective aortic valve replacement was planned. Pre-operative cardiac scintigraphy (¹²³I-BMIPP) showed total defect of myocardial uptake. CD 36 deficiency was diagnosed based on the characteristic findings. CD 36 deficiency could cause transfusion related complication by donor blood transfusion. We prepared 1,200 ml autologous blood preoperatively in a two week period. The operation was performed successfully without donor blood transfusion. He was discharged uneventfully.

Homozygous familial hypercholesterolemia is a rare metabolic disorder with characteristic clinical presentations, such as tendon xanthomas, hypercholesterolemia, and significant cardiovascular disease including premature coronary artery disease. We describe a case of a 56-year-old woman with homozygous familial hypercholesterolemia. She had been treated with low-density lipoprotein apheresis for 23 years. Preoperative echocardiography and coronary angiography showed severe aortic valve stenosis and right coronary artery stenosis. Aortic valve replacement with patch enlargement of the aortic valve annulus, and coronary artery bypass grafting were successfully performed. She was discharged uneventfully.

Patients with an aortic root pseudoaneurysm communicating to the right atrium are rare. A 67-year-old woman underwent ascending aorta and total aortic arch replacement for acute type A aortic dissection at our institute 9 years prior to the current presentation. She was transported to our emergency department with complaints of chest pain, palpitations, and cold sensation. A continuous murmur was heard at the right sternal margin. Contrast-enhanced computed tomography (CT) and ultrasonic cardiography showed a huge pseudoaneurysm at the proximal anastomotic site and an aorto-right atrial fistula. Ascending aortic replacement with concomitant direct closure of the fistula was successfully performed. The patient was discharged in good condition on the 14th postoperative day. Careful follow-up with CT is important after acute type A aortic dissection repair.

A 57-year-old man, who had suffered chest, back and right leg pain about 10 years before, underwent CT and was found a chronic type B aortic dissection with an enlarged false lumen and a narrowed true lumen that was occluded at the infrarenal abdominal aorta. A conventional surgical repair seemed to be too high risk considering his comorbidities, thus we chose a staged hybrid repair. First, surgical repair of the abdominal aorta with an abdominal aortic fenestration was performed. Then, one month after the first operation, zone 2 thoracic endovascular aortic repair with left carotid-axillary artery bypass was performed. At the second operation, the stent graft was purposely deployed from zone 2 into Th12 level of a false lumen through the fenestration followed by coil embolization of a true lumen just distal to the entry tear. The postoperative course was uneventful and he had no complications at 6 months follow-up. Deploying stent graft into a false lumen could be a feasible option in case deploying into a true lumen is not suitable if the anatomical condition permits.

Objectives: This study examined the effects of the interaction between exercise and sleep on frailty severity in community-dwelling older adults.Materials and Methods: This was a cross-sectional study. Data were collected in July 2019. In total, 2021 adults participated who responded to a questionnaire. Among them, 672 participants (317 men and 355 women) with valid responses were included in the analysis. Ordinal logistic regression analysis was performed to examine the association between frailty severity and the interaction between exercise and sleep. The dependent variable represents three different levels of frailty. The independent variables included basic information and interaction between exercise and sleep.Results: The results of ordinal logistic regression analysis (odds ratio [OR]) showed that the period from the start of exercise (OR=0.96), age (OR=1.00 for participants in their 60 s, OR=1.65 for those in their 70s, and OR=3.13 for those aged >80 years), poor subjective health perception (OR=2.12), poor quality of sleep (OR=1.88), stress (OR=1.62), and exercise–sleep interaction (OR=1.00 based on good-exercise–good-sleep interaction, OR=3.09 poor-exercise–good-sleep interaction, and OR=3.50 poor-exercise–poor-sleep interaction) significantly contributed to the model. The Nagelkerke coefficient of determination adjusted for degrees-of-freedom (R2), which represents the contribution rate of the regression equation, was 0.334.Conclusions: Our results suggest that a combination of good exercise and good sleep is needed to prevent frailty progression in community-dwelling older adults.

We report a 48-year-old man who underwent hybrid aortic repair for visceral aortic patch (VAP) aneurysm. He had undergone descending thoracic aortic repair for post-dissection aneurysm at the age of 25, ascending aorta and proximal aortic arch aneurysm repair at the age of 27, and residual thoracoabdominal dissecting aortic aneurysm repair with VAP reconstruction at the age of 28. During 20 years of follow-up, the VAP gradually enlarged and eventually reached 70×61 mm in diameter. Considering a possible severe adhesion after 2 previous left thoracotomies, we planned a 2-staged hybrid aortic repair. First, we performed reno-visceral debranching and as a second stage operation, endovascular aortic repair was performed successfully 39 days after the first-stage operation.
