Abstract
BACKGROUND The treatment of patients with infective endocarditis (IE) who have preoperative cerebral complications remains less understood. Therefore, this study aimed to retrospectively evaluate the clinical outcomes of patients with acute IE based on preoperative intracranial findings. METHODS Of 32 patients with acute IE treated at our hospital between August 2015 and March 2022, 31 patients of whom preoperative intracranial imaging evaluation was available were included in our analysis and compared with those with and without intracranial findings. We controlled the mean arterial blood pressure and activated clotting time (ACT) to prevent abnormally high perfusion pressures and ACTs during cardiopulmonary bypass (CPB). The preoperative background, and postoperative courses focusing on postoperative brain complications were reviewed. RESULTS Among the 31 patients, 20 (65%) had preoperative imaging findings. The group with intracranial findings was significantly older, with more embolisms in other organs, positive intraoperative pathology findings, and longer CPB times. A new cerebral hemorrhage developed postoperatively in one patient without intracranial findings. There were no early deaths; two patients had recurrent infections in each group, and one died because of sepsis in the late phase in the group with intracranial findings. CONCLUSIONS Positive intracranial findings indicated significantly active infectious conditions preoperatively but did not affect the postoperative course. Patients without preoperative cerebral complications can develop serious cerebral hemorrhage. Although meticulous examination of preoperative cerebral complications in all patients with IE is essential, a strategy should be adopted to prevent cerebral hemorrhage, even in patients without intracranial findings.

Abstract
The Frozenix J graft open stent graft (Japan Lifeline, Tokyo, Japan) has been available since 2014 in Japan. This stent is widely used for the frozen elephant trunk technique in many institutions, mainly for cases of acute type A aortic dissection and also for cases of a true aneurysm and chronic aortic dissection. We experienced a rare case in which the metal wires of the Frozenix J graft were broken and embolized to the periphery half a year after implantation.

Abstract
Objective: Total aortic arch replacement (TAR), particularly in individuals with extensive atherosclerotic alterations, especially shaggy aortas, is more crucial and difficult. The objective of this retrospective investigation was to ascertain if patients with shaggy aortas would respond to modified isolated cerebral perfusion (ICP). Materials and Methods: Between 2015 and 2020, nine individuals with shaggy aortas who received treatment for arch aneurysms were examined. Four and five patients, respectively, who had arch replacement with traditional selective cerebral perfusion (SCP) and modified ICP, were evaluated, and their short- and long-term results were compared. Results: There were no appreciable variations in the postoperative results between patients with traditional SCP and those with modified ICP. Following surgery, one patient developed paraparesis, while two individuals with traditional SCP experienced persistent neurological damage. In patients with modified ICP, there were no postoperative neurological or other problems associated to atherosclerosis; nevertheless, one patient experienced stroke 5 months after surgery. Conclusion: Patients with shaggy aorta may not receive enough brain protection from TAR with standard SCP because single axillary artery perfusion can result in nonphysiological flow and atheroma separation. Even in patients with shaggy aortas, TAR with modified ICP is safe, but late-phase severe adverse cerebrovascular events should be taken into account.

Abstract
A 52-year-old man presented with temporal haemoptysis and chest pain 6 months after radiofrequency catheter ablation for atrial fibrillation. Computed tomography revealed severe stenosis in the left upper pulmonary vein (PV) and complete occlusion of the left lower PV. A modified sutureless repair of the left PV obstruction was successfully performed. This modified procedure provides a feasible, safe and effective means of treating PV obstruction, even in cases with distal extension of stenosis.

Abstract
Background Despite continuous developments and advances in the perioperative management of patients suffering from acute aortic dissection type A (AADA), the associated postoperative morbidity and mortality remain high and strongly depend on the preoperative clinical status. The associated postoperative mortality is still hard to predict prior to the surgical procedure. The so-called German Registry of Acute Aortic Dissection Type A (GERAADA) score uses very basic and easily retrievable parameters and was specifically designed for predicting the 30-day mortality rate in patients undergoing surgery for AADA. This study evaluated impact of the GERAADA score in the authors’ institutional results. Methods Among 101 acute type A aortic dissection patients treated at our hospital during August 2015–March 2021, the GERAADA was calculated individually and retrospectively. Predicted and actual mortalities were assessed, and independent predicted factors were searched. The primary endpoint was defined as comparison of GERAADA scores and early mortality, and the secondary endpoints were defined as comparison of GERAADA scores and other postoperative results, and comparison of preoperative factors and postoperative results regardless to GERAADA scores.
Results While the overall 30-day mortality for the entire study cohort calculated by the GERAADA score was 14.3 (8.1–77.6)%, the actual mortality rate was 6%. However, the GERAADA score was significantly high in some postoperative complications and showed significant correlation with some peri- and post-operative factors. In addition, factors not belonging to GERAADA score such as time from onset to arrival at the hospital, time from onset to arrival at the operation room, spouse presence, and hemodialysis were significantly associated with 30-day mortality. Conclusions Although the actual mortality was lower than predicted, GERAADA score may impact on the postoperative course. In addition, it would be desirable to add parameters such as the time from onset to arrival, family background, and hemodialysis for further accuracy.

Abstract
Life‐threatening cardiac events may be misdiagnosed as acute aortic dissection because of notable symptom mimicry. We report the case of a 72‐year‐old male patient with presentations presumed to be of aortic origin. However, surgery revealed posterior free‐wall perforation in the left ventricle caused by the occlusion of an obtuse marginal branch.

Abstract
Cardiac injury, including myocardial contusion and valvular damage, is a common complication of blunt chest trauma; however, traumatic ventricular septal rupture is a rare complication. We encountered a rare case of ventricular septal rupture following blunt chest trauma that was successfully repaired by emergency surgery. The mechanism underlying rupture may involve acute compression of the heart between the sternum and the vertebral column when the ventricle is filled, thereby causing a sudden increase in intraventricular pressure and leading to septal rupture. Emergency operation should be considered in cases of large defects and hemodynamic instability.

Abstract
Background: Several authors have investigated various sternal closure materials and technologies for sternal fixation; nonetheless, the optimal technique for primary sternal closure remains unclear. This study aimed to evaluate the sternal stability of a simple technique using a mesh-type plate (Super Fixorb MX40®; Takiron Co. Ltd., Osaka, Japan), as compared with wire cerclage.
Methods: A total of 70 patients who underwent cardiovascular surgery through median sternotomy between July 2019 and May 2020 were included. Two pieces of mesh-type plates were placed under the sternum in combination with wiring. The technique for sternal closure was randomly applied, which was mainly based on the surgeon’s preferences: mesh plate (mesh group: N = 33) or conventional wire cerclage (wire group: N = 37). Sternal displacement was measured using computed tomography at discharge.
Results: Pain scale scores and analgesic use on postoperative day 7 were similar between the two groups. However, the displacement in both the anterior-posterior and lateral directions was significantly smaller in the mesh group.
Conclusions: The use of the mesh plate device for sternal closure is simple, safe, easy, and potentially reliable without anterior-posterior sternal displacement.

Abstract
OBJECTIVES This study aimed to investigate whether tracheostomy timing in patients undergoing cardiac surgery had an impact on outcomes. DESIGN Retrospective, observational study. SETTING Single-center university hospital. PARTICIPANTS Patients requiring tracheostomy among a total of 961 patients who underwent cardiovascular surgery via a median sternotomy from January 2014 to March 2021. INTERVENTIONS Early versus late tracheostomy. MEASUREMENTS AND MAIN RESULTS During the study period, tracheostomy was performed in 28 patients (2.9%). According to tracheostomy timing, postoperative day seven was chosen as the cutoff to define early (≤seven days) and late (>seven days) tracheostomy. Patients in the early-tracheostomy group had a significantly shorter ventilation time after tracheostomy compared with the late-tracheostomy group (p = 0.039), and early tracheostomy resulted in a reduction in total ventilation time (p = 0.001). The incidence of pressure ulcers was significantly lower in the early-tracheostomy group compared with the late- tracheostomy group. There was a higher tracheal tube removal rate in the early-tracheostomy group compared with the late-tracheostomy group (p = 0.0007). The one-year survival rate in the early- and late-tracheostomy groups was 65% and 31%, respectively. The long-term mortality rate was significantly lower in the early-tracheostomy group compared with the late- tracheostomy group (p = 0.04). CONCLUSIONS Early tracheostomy (<seven days) may provide better clinical outcomes, with lower mortality and morbidity rates, when patients are judged to require at least seven days of ventilation after cardiovascular surgery.

Purpose: Unlike loop diuretics, tolvaptan is reported to have a renal protective effect. The purpose of this study was to retrospectively assess the efficacy of tolvaptan administration in chronic kidney disease (CKD) patients following open-heart surgery. Methods: From February 2017 to August 2020, 75 patients with preoperative CKD stages IIIb–V were enrolled in this study and were divided into two groups: the control group (n = 30) and the tolvaptan group (n = 45). All patients routinely received conventional diuretics starting from postoperative day (POD) 1. Tolvaptan at 7.5–15 mg/day was administered if the patients had persistent fluid retention or poor response to conventional diuretics. Results: Tolvaptan administration was initiated at a mean of POD 2.9 ± 2.2, and the mean dosing period was 4.1 ± 3.0 days. The mean time to return to the preoperative body weight in the control and tolvaptan groups was similar. However, estimated glomerular filtration rate (eGFR) was significantly increased at the time when body weight reached the preoperative level and at discharge in the tolvaptan group than in the control group. Conclusion: This study demonstrated the renal protective effect of tolvaptan even in advanced CKD patients after open-heart surgery.

Abstract
Objectives Acute type A aortic dissection complicated with brain ischemia is associated with significantly higher mortality risks. Even if rescued with central aortic repair, some patients develop permanent postoperative neurological deficiency postoperatively. We recently introduced direct common carotid artery perfusion for acute type A aortic dissection involving the common carotid artery. This study introduced this technique to prevent postoperative neurological deficiency by comparing brain protection strategies. Methods Among 91 acute type A aortic dissection patients treated at our hospital during August 2015–October 2020, the common carotid artery was involved in 19 (21%), which had > 90% stenosis in either of the carotid arteries on preoperative contrast-enhanced computed tomography. Twelve patients underwent conventional selective cerebral perfusion during August 2015–December 2018 and seven patients underwent direct carotid artery perfusion during January 2019–October 2020. We assessed patient characteristics, surgical courses, clinical outcomes, and neurological outcomes. Results The mean age was 69 (range 39–84) years; 17 patients were male (89%). Eight patients (42%) had neurological symptoms. Concomitant procedures, postoperative neurological symptoms, and late mortality were significantly associated with conventional selective cerebral perfusion. Five selective cerebral perfusion patients experienced worsened neurological symptoms and two died of broad cerebral ischemia. No direct carotid artery perfusion patient died during hospitalization or experienced worsened neurological outcomes. Conclusions Direct carotid artery perfusion may be useful in aortic dissection with brain ischemia because it does not aggravate neurological symptoms and is not associated with intraoperative cerebral infarction. However, it may be ineffective when cerebral infarction has already developed.

Abstract
Background Takayasu arteritis (TA) is a chronic inflammatory disease that induces stenosis, occlusion, or aneurysmal degeneration of the aorta and its major branches. Though rarely reported, proximal aneurysmal lesions from the aortic root to the arch are more common in Asian populations than in Western populations. In the surgical treatment of TA, anastomotic aneurysm can be problematic. Furthermore, atherosclerotic complications should be considered in surgical treatment for elderly TA patients. Case presentation Here, we report a case of brachiocephalic artery (BCA) aneurysm with TA for which surgical treatment was successful. Though it was solely a lesion of the brachiocephalic artery, after considering the patient’s clinical background and the features of TA, we chose a partial arch replacement. Further, for avoidance of anastomotic aneurysm, both distal and proximal anastomosis were reinforced with Teflon felt strips. Preoperative computed tomography detected severe atherosclerotic changes in the arch vessels. The patient underwent partial arch replacement using isolated cerebral perfusion (ICP) for brain protection and recovered without any neurological deficits. Conclusions In avoidance with anastomotic aneurysm, reinforcement of the anastomosis was introduced. ICP was effective for brain protection in case with severe atherosclerotic changes.

Abstract
Surgery for prosthetic valve endocarditis in the mitral valve position is still challenging for surgeons. Reconstruction of the mitral annulus is useful for patients with a mitral annulus disputed by infection. Here, we report a redo mitral valve replacement using a collar-reinforced tissue valve, which was inserted into a mitral annulus reconstructed with a bovine patch. Though the preoperative blood culture detected Streptococcus anginosus, the intraoperative culture detected methicillin-resistant coagulase-negative staphylococci (MRCNS). MRCNS is rarely detected because of its indolent nature.

Abstract
Few studies have reported resternotomy after an omental flap procedure. We describe the case of a 78-year-old man who received resternotomy after omental flap procedure for deep sternal wound infection and successfully underwent coronary artery bypass grafting. Although preoperative computed tomography showed funnel chest and limited space between the sternum and omentum, resternotomy was performed safely using circular electric sternum saw under partial cardiopulmonary bypass. Because the omentum functioned as cushioning material between the sternum and mediastinal organs, no injuries of the mediastinal organs occurred. An ultrasonic scalpel effectively dissected between the omentum and mediastinal organs, especially above the ascending aorta. The targeted coronary arteries were easily detected. The patient experienced no major cardiac or infectious events for three months. An ultrasonic scalpel is recommended for dissecting between the omentum and mediastinal organs.

Abstract
We report the successful repair in a 29-year-old man who experienced penetration of the ascending aorta and bronchus by a crossbow bolt. Imaging studies revealed the arrow penetrating the sternum, right lung, ascending aorta and right bronchus, with mediastinal emphysema. The top of the arrow (8 mm in diameter) was deeply embedded in the body of the thoracic vertebra. The arrow was successfully removed while maintaining a stable respiratory condition by performing differential lung ventilation. There was no need for cardiopulmonary bypass. To our knowledge, this is the first case of a through-and-through penetrating ascending aorta injury.

Abstract
Background Left ventricular (LV) pseudo-false aneurysm is a rare complication secondary to myocardial infarction and is caused by intramyocardial dissecting hematoma due to fragile myocardium. Very occasionally, intramyocardial dissecting hematoma appears as a neocavitation entirely contained within the myocardial wall (so called “pseudo-false LV”) and is an unusual form of subacute cardiac rupture. Case presentation A 38-year-old male experienced chest discomfort 3 weeks ago, which improved within few days. However, after that episode, he presented at our hospital with rapidly deteriorating severe breathlessness in a preshock state with acute heart failure. Emergency coronary angiography revealed an occluded left anterior descending artery. An intra-aortic balloon catheter was inserted because of unstable hemodynamics. Enhanced computed tomography revealed extensive aneurysm formation in the LV anterior wall and contrast leakage from the inner cavity to the LV myocardium, with a moderately accumulated pericardial effusion. Emergency surgery revealed a large aneurysmal sac on the anterior wall, slightly attached to the pericardium. A 5-mm, slit-like, oozing-type, rupture site was detected in the LV after dissecting the pericardium. Conclusions To our knowledge, this is the first report of a pseudo-false aneurysm on the LV anterior wall. Subacute rupture of pseudo-false LV aneurysm is rare.

Abstract
Postinfarction ventricular septal defect has been a challenge to cardiac surgeons. Recently, a number of reports have recommended ventricular septal defect closure through the right ventricle. However, when inferior myocardial infarction widely extends to the left ventricle, it is necessary to modify a patch-closure technique due to extensive fragile necrotic myocardium. We describe a simplified surgical technique via a right ventricular incision.

Abstract
We describe a case of infective endocarditis caused by Campylobacter fetus accompanied by pulmonary emboli. A 52-year-old man was referred to our hospital due to febrile temperatures with a history of dental treatment followed by eating raw meat. Computed tomography revealed multiple infiltrations and a nodule with low attenuation area and feeding vessels. A mobile mass, possible vegetation, attached to the tricuspid valve was detected by transthoracic echocardiography. Two blood cultures disclosed Campylobacter fetus. Long-term antibiotic therapy was given, curing the infection with valvuloplasty. We presented the possibility that infective Campylobacter fetus endocarditis after dental treatment was caused by eating raw meat.

Abstract
N-terminal peptide of proopiomelanocortin (NPP, or pro-gamma-MSH) has shown to exhibit biological activity such as stimulation of adrenal mitogenesis and prolactin release-inhibiting factor activity. Structurally, studies reveal a significant difference between fish NPP from that of tetrapods, as NPPs from carp and salmonid lack gamma-MSH. Thus, fish NPP may exhibit functions different from that of mammals. The activation of phagocytic cells by NPP was analysed using rainbow trout Oncorhynchus mykiss and carp Cyprinus carpio. Rainbow trout and carp macrophages incubated with chum salmon NPP significantly enhanced the production of superoxide anion in comparison with control macrophages (without hormones). Both rainbow trout and carp macrophages had shown increased phagocytosis when stimulated administered with NPP. The above results were complemented by in vivo studies where NPP was administered to rainbow trout and carp. NPP significantly increased superoxide anion production as well as phagocytosis in macrophages. These results show that NPP in lower vertebrates activates the function of the phagocytic cells.

Abstract
The modulation of phagocytic cells by beta-estradiol, 11-ketotestosterone and progesterone was analyzed in common carp Cyprinus carpio. Carp kidney leukocytes were cultured in RPMI 1640 medium containing 0.1, 1, 10, 100 or 1000 nM concentration of each hormone. The production of superoxide anion, nitric oxide (NO) and phagocytosis were measured in vitro. Similar concentrations of cortisol were used as control. Phagocytic activities of carp macrophages was suppressed by treatment with beta-estradiol, progesterone and 11-ketotestosterone. The production of NO in carp macrophages was suppressed by progesterone and 11-ketotestosterone. However, carp macrophages incubated with beta-estradiol, progesterone and 11-ketotestosterone did not show any difference in the production of superoxide anion in comparison with control macrophages in the absence of hormones. Carp macrophages treated with cortisol suppressed phagocytosis and the production of nitric oxide and superoxide anion.

Abstract
The activation of rainbow trout, Oncorhynchus mykiss, and carp, Cyprinus carpio, phagocytic cells by synthetic chum salmon, O. keta, beta-endorphin was analysed in vitro. Rainbow trout head kidney leukocytes were cultured in RPMI 1640 medium containing 1, 10, 50 or 100 ng ml-1 of chum salmon beta-endorphin and the production of superoxide anion was measured via the reduction of nitroblue tetrazolium (NBT) in vitro. Macrophages incubated with 10 ng ml-1 up to 100 ng ml-1 of beta-endorphin showed an increase in their production of superoxide anion in comparison with control macrophages which were cultured without hormone. beta-endorphin also increased the production of superoxide anion in phagocytic cells prepared from kidney of carp. This stimulation was inhibited by naloxone. Phagocytic cells treated with beta-endorphin also displayed increased phagocytic activity and phagocytic index. These results showed that beta-endorphin in lower vertebrates activates the function of phagocytic cells in vitro.

Abstract
The effects of two peroxisome proliferators, p-chlorophenoxyisobutyric acid (clofibric acid) and 2,2'-(decamethylenedithio)diethanol (tiadenol), on cytosolic long-chain acyl-CoA hydrolase and peroxisomal beta-oxidation were studied in several organs of rat. Among organs of control rats, the brain had the highest activity of long-chain acyl-CoA hydrolase, followed by testis, and a low activity was found in other tissues. Administration of the peroxisome proliferators caused a marked increase in activity of long-chain acyl-CoA hydrolase in both liver and intestinal mucosa and a slight increase in the activity in kidney, but little affected acyl-CoA hydrolase activity in either brain, testis, heart, spleen and skeletal muscle. In accordance with the change in the activity of acyl-CoA hydrolase, the activity of peroxisomal beta-oxidation was markedly increased in liver, intestinal mucosa and kidney, and a slight increase was found in brain and testis, whereas peroxisome proliferators little affected the activity in other organs tested. Gel filtration of cytosol from intestinal mucosa showed that clofibric acid caused an appearance of a new peak in intestinal mucosa. Although cytosol of liver, intestinal mucosa, brain and testis contained two 4-nitrophenyl acetate esterases with different molecular weights (about 105,000 and about 55,000), these esterases are different from cytosolic long-chain acyl-CoA hydrolases of these four organs in respect of molecular weight. The administration of clofibric acid little affected cytosolic 4-nitrophenyl acetate esterases. Comparative studies on cytosolic long-chain acyl-CoA hydrolases from these four organs showed that liver hydrolase I (molecular weight of about 80,000) had properties similar to those of brain and testis enzymes. On the other hand, intestinal mucosa enzyme was different from either hepatic hydrolase I or II (molecular weight of about 40,000). The results from the present study suggest that inductions of peroxisomal beta-oxidation and cytosolic long-chain acyl-CoA hydrolases are essential responses of rats to peroxisome proliferators not only in liver but also in intestinal mucosa and that induced hydrolases are not attributable to non-specific esterases.

Abstract
Inductions of FABP in hepatic cytosol by administration of tiadenol and clofibric acid were studied in rats, mice and guinea-pigs. In rats and mice, [1-14C]oleic acid-binding capacity of hepatic cytosol was increased, in association with induction of peroxisomal beta-oxidation, by the administration of either the two peroxisome proliferators. The increase in [1-14C]oleic acid binding capacity was responsible for the increase in the content of FABP in livers. The peroxisome proliferators caused an induction of acyl-CoA hydrolase of lower-molecular-weight form alone in hepatic cytosol of mice, although inductions of two long-chain acyl-CoA hydrolases (higher- and lower-molecular-weight form) were brought about in hepatic cytosol of rats. Guinea-pigs lacked the peroxisome proliferator-caused inductions of FABP, peroxisomal beta-oxidation and acyl-CoA hydrolase. There was no essential difference in the inductions of FABP, acyl-CoA hydrolases and peroxisomal beta-oxidation between tiadenol and clofibric acid, despite a marked difference in their chemical structures. These results suggest that the induction of FABP is correlated with the inductions of both peroxisomal beta-oxidation and cytosolic long-chain acyl-CoA hydrolase of lower-molecular-weight form.

Abstract
Rats were fed a diet containing clofibric acid or tiadenol. The treatment of rats with clofibric acid caused an increase in the activity of cyanide-insensitive palmitoyl-CoA oxidation and in the concentration of a polypeptide with a molecular weight of about 80,000 in the light mitochondrial fraction in intestinal mucosa. Treatment of rats with tiadenol increased the activity of cyanide-insensitive palmitoyl-CoA oxidation more markedly than with clofibric acid. The induced activity in intestinal mucosa was about 1/10th that in liver. Treatment of rats with either of the two peroxisome proliferators increased both [1-14C]oleic acid binding capacity and the concentration of FABP in intestinal mucosa of rats. The treatment of rats with clofibric acid did not seem to alter the properties of FABP found in intestinal mucosa.

Abstract
Long-term effects of rho-chlorophenoxyisobutyric acid (clofibric acid) on inductions of peroxisomal beta-oxidation, fatty acid-binding protein and cytosolic acyl-CoA hydrolases in rat liver were studied. Male rats were fed clofibric acid at a dietary concentration of 0.25% for 22 weeks. The induction of peroxisomal beta-oxidation activity lasted throughout the long-term treatment of rats, the activity being a half that of rats treated with clofibric acid for 2 weeks. cytosolic long-chain acyl-CoA hydrolase I and II were both induced by the long-term and the short-term treatment of age-matched rats with clofibric acid, although the ability to induce hydrolase I decreased greatly by aging of rats. There was little difference in the inducing effect on fatty acid-binding protein between the long-term treatment and the short-term treatment. These results suggest that the inductions of peroxisomal beta-oxidation, fatty acid-binding protein and two cytosolic long-chain acyl-CoA hydrolases are essential responses of rats to clofibric acid (but not the brief events which occur in only the first stage of the continuous treatment with clofibric acid).
