A 62-year-old man had suffered from massive pedal edema, dyspnea and sinus bradycardia for 10 days. He had been heavy drinker for over 20 years. He was transferred to our hospital with severe heart failure. Echocardiography showed severe diffuse hypokinesis of left ventricular wall motion (EF20%) with dyssynchrony, and thrombus in the left ventricular apex. Under a diagnosis of LV thrombus due to severe heart failure, we made a plan for an emergency open heart surgery, but it could not be performed because of initial cardiogenic embolic stroke. Therefore, we waited for 2 weeks while performing anticoagulation therapy. The removal of LV thrombus and atrio-biventricular pacing for heart failure due to dyssynchrony were performed 2 weeks later. The pathological specimen of myocardium showed marked fibrous and hypertrophic change, which were similar to idiopathic dilated cardiomyopathy. Alcoholic cardiomyopathy due to alcohol intake for many years is similar to a clinical image of dilated cardiomyopathy, but its clinical prognosis by abstinence is not bad. In this case we performed an urgent open heart surgery due to cardiogenic embolic stroke, but must be essentially performed as an emergency operation. Postoperative course was uneventful and he was discharged 21 days after open heart surgery without any complications.

We report a rare case of a 70-year old woman who suffered right ventricular failure and shock with a comparatively rapid course due to a huge primary right atrial malignant lymphoma occupying the right atrium. She had undergone mitral valve replacement and tricuspid valve annuloplasty due to combined valvular disease 12 years previously, and she had been treated for liver cirrhosis due to hepatitis C. The transthoracic echocardiography and the computed tomography scan revealed a huge tumor occupying the right atrial cavity and incarceration into the tricuspid valve ring. We performed an emergency operation to resect the heart tumor. As the tumor strongly adhered to the free wall of the right atrium and the tricuspid valve ring, we performed complete resection of the right atrial free wall and tricuspid valve. Therefore, we performed tricuspid valve replacement with a bioprosthesis, and reconstruction of the right free wall with an EPTFE sheet. The pathological examination of the tumor was consistent with malignant lymphoma of B-cell origin. These surgical procedures were effective to reduce acute right heart failure due to severe tricuspid valve regurgitation, but she died 3 months after surgery because of liver failure due to cirrhosis. Even though the operation was not curative, it might have been effective for preventing sudden death and acute right ventricular heart failure due to incarceration into the tricuspid valve ring of the huge right atrial tumor.

A 78-year-old man underwent replacement of a descending thoracic aorta in 1980 using a Cooley double velour knitted Dacron (CDVKD) following a diagnosis of DeBakey type III b aortic dissection. He had back pain and bloody sputum from around January 2012, and so the patient was referred to our department. Upon multi-detector computed tomography (MDCT), we diagnosed a graft aneurysm caused by the prosthetic graft carried out 32 years previously that had expanded to a maximum of greater than 80 mm. An emergency operation was considered due to the continuing back pain and bloody sputum. As a strategy for treatment, low invasive treatment by thoracic endovascular aortic repair (TEVAR) was initially planned. However, due to the large size of the aneurysm relative to the surrounding vessels and severe aortic calcification of the landing zone, complications of endoleak and migration were considered possible upon TEVAR. Instead, we selected total aortic arch replacement with extracorporeal circulation upon median sternotomy, even though this required increased surgical invasion. Postoperative prognosis was good and the patient was discharged from hospital 5 weeks following surgery. There are few reports on the failure of a prosthetic graft causing a graft aneurysm, particularly involving an aging CDVKD graft, but it is possible that deterioration of a prosthetic graft may cause a graft aneurysm. Therefore, postoperative follow-up must be carried out with care.

A 39-year-old man was admitted to our hospital with symptoms of anterior chest pain and slightly dyspnea. At that time, he had chest discomfort, hypertension, and with enlargement of mediastinal shadow on chest X ray. Medical treatment rapidly improved the hypertension and the other symptoms. Transthoracic echocardiography (TTE) and enhanced chest CT revealed aortic root dilation, and trivial aortic valve regurgitation, but these examinations could not identify the cause of such as typical Stanford type A dissection. Transesophageal echocardiography (TEE) and chest MD-CT were undertaken on 7 days after the admission revealed a localized aortic dissection, intimal flap, and enlargement of sinotubular junction (STJ). An Urgent operation was performed. During the operation, a localized aortic dissection appeared to be above the left coronary cusp through the right coronary cusp of the aortic valve, but the valve findings were normal, so we decided to perform a aortic valve remodeling operation. The aortic sinuses were excised leaving 4 mm of arterial wall attached to the aortic annulus and around the coronary arteries. A Woven Dacron graft of diameter equal to the diameter of the STJ was tailored to recreate three aortic sinuses. The three commissures were suspended into the tailored graft and the neo-aortic sinuses were sutured to the aortic annulus and remnants of arterial wall. The coronary arteries were reimplanted into their respective neo-aortic sinuses and the graft anastomosed to the distal aorta. The postoperative course was uneventful. We concluded that this procedure is useful for a localized aortic dissection around the coronary orifice.

A 40-year-old woman visited our emergency room (ER) with fever and shaking chills. Blood cultures for suspicion of urinary tract infection revealed bacteremia two days later. Since Streptococcus mitis was detected, infective endocarditis was strongly suspected. In addition to her history of dental calculus removal, careful cardiac auscultation revealed a continuous murmur, leading to the existence of patent ductus arteriosus (PDA). PDA was confirmed by echocardiography and 3D-CT angiography. The patient was successfully treated by antibiotics and then received transcatheter PDA closure. Careful auscultation after detection of bacteremia led to a diagnosis of PDA.

A 68-year-old man presented to the emergency department with a high fever of 39.0 degrees Celsius. His past surgical history was significant, including mitral valve replacement and, tricuspid valve annuloplasty in 2012. On echocardiography, multiple vegetation with a maximum diameter of 20 mm was identified on the leaflet of the prosthetic valve. The vegetations were large, multiple, and appeared floating. Moreover, advanced prosthesis valve regurgitation was observed. Candida grablata was detected in the blood culture, suggesting a high probability of PVE due to fungal infection. Emergency surgery was performed to prevent deterioration of his condition. Multiple large vegetations were noted attached to the prosthetic valve, resulting in damage to the valve leaflets and subsequent stenosis. The operation was concluded following removal of the last prosthetic valve and re-enforcement of the MVR. After surgery, antibiotic therapy with amphotericin B liposome was administered. Given that there were no signs of infection, the patient was discharged from the hospital on the 50th day after surgery. Although the vegetation was deemed large with a likelihood of patient deterioration, we believe that the degree of destruction to the leaflets prevented fatality. Existing literature reported cases whereby patients were discharged despite having such large vegetation on the valve. In cases of fungal infective endocarditis (Fungal IE), regardless of whether the valve was natural or prosthetic, the optimal treatment is to combine infected tissue debridement with thorough lesion removal, valve replacement surgery or valve annuloplasty, supplemented with a long-term antifungal agent. We believe this to be an effective treatment, especially if intervention is implemented early.

Total anomalous pulmonary venous connection (TAPVC) is rarely associated with remarkably small left heart structures. In these types of cases, the hemodynamics resembles that of hypoplastic left heart syndrome, and the treatment strategy is controversial. We present the case of a 1-day-old girl with infracardiac TAPVC, small left heart structures (hypoplastic left heart complex), bilateral superior vena cava, and aberrant origin of the right subclavian artery. We performed a semi-emergent first-stage open palliation for repair of TAPVC, because of pulmonary venous obstruction. We concomitantly performed atrial septal defect (ASD) enlargement and bilateral pulmonary artery banding (BPAB). The postoperative course was uneventful and the left heart structures did not grow, so we performed the Norwood procedure and placed a right ventricle-pulmonary artery shunt with a 5.0 mm artificial graft. Subsequently, the left heart structures were not suitable for biventricular repair, so we chose univentricular repair. The patient underwent a bilateral bidirectional Glenn operation and Fontan completion at 6 and 23 months of age, respectively. TAPVC repair, BPAB, and ASD enlargement are reasonable surgical options for a patient with borderline small left heart structures and TAPVC, as they enable us to wait for growth in the left heart structures and to determine whether univentricular or biventricular repair is suitable.

Background/Aims: Mucosal adaptation of the ileum toward colonic epithelium has been reported in pouchitis in ulcerative colitis (UC); however, the clinical characteristics, endoscopic findings, and outcomes in patients with pouchitis with ileal mucosal adaptation are poorly understood. Methods: This was a single-center retrospective study comprising UC patients treated by proctocolectomy with ileal pouch-anal anastomosis who had undergone pouchoscopy at the University of Tsukuba Hospital between 2005 and 2022. Endoscopic phenotypes were evaluated according to the Chicago classification. High-iron diamine staining (HID) was performed to identify sulfomucin (colon-type mucin)-producing goblet cells (GCs) in pouch biopsies. We compared clinical data between patients with (high HID group) and without > 10% sulfomucin-producing GCs in at least one biopsy (low HID group). Results: We reviewed 390 endoscopic examination reports from 50 patients. Focal inflammation was the most common phenotype (78%). Five patients (10%) required diverting ileostomy. Diffuse inflammation and fistula were significant risk factors for diverting ileostomy. The median proportion of sulfomucin-producing GCs on histological analysis of 82 pouch biopsies from 23 patients was 9.9% (range, 0%–93%). The duration of disease was significantly greater in the high HID group compared to the low HID group. The median percentage of sulfomucin-producing GCs was significantly higher in patients with diffuse inflammation or fistula compared to other endoscopic phenotypes (14% vs. 6.0%, P= 0.011). Conclusions Greater proportions of sulfomucin-producing GCs were observed in endoscopic phenotypes associated with poor outcomes in UC, indicating patients with pouchitis showing colonic metaplasia of GCs may benefit from early interventions.

The purpose of this study was to examine the effects of aquatic exercise training on the trunk muscles function and activities of daily living in abdominal obese women. Nineteen abdominal obese (abdominal circumference: 90 cm or more) and fifteen age-matched non-obese women were recruited as participants in this study. The aquatic exercise training (60 min/day, three days/week for 8 weeks) based on abdominal twists for activating the trunk muscle function. Physical parameters, biochemical characteristics, arteriosclerotic parameters and activities of daily living scores were assessed before and after the training period. In both groups showed abdominal circumference, percent of body fat, blood pressure and lower extremity muscle strength increased significantly after aquatic exercising training. In particular, endurance capacity of abdominal and back muscles increased significantly and activities of daily living scores were significantly improved in the obese group. Moreover, the improvement in the strength of lower extremities and improvement in the activities of daily living scores, such as climbing and descending stairs, in the obese group tended to be higher than non-obese women. Additionally, in abdominal obese group, the amount of the reduction of abdominal circumference was significantly associated with that of the increase in the strength of lower extremities. Taken together, these findings suggest the possibilities that the present aquatic exercise training based on trunk muscle exercise improving the function of trunk and lower extremity muscles with reduction in the abdominal obesity, contributing to improve activities of daily living in abdominal obese women.

Background/Aims: This study aims to evaluate the presence of laryngopharyngeal reflux (LPR) and to investigate the use of hypopharyngeal baseline impedance (BI) for assessing swallowing dysfunction and gastroesophageal reflux disease (GERD) using hypopharyngeal multichannel intraluminal impedance and pH (HMII-pH) monitoring in neurologically impaired patients (NIPs). Methods: The study population in this retrospective study comprised 20 NIPs (mean age, 36.1 ± 15.0 years; age range, 13-64 years) who underwent multichannel intraluminal impedance and pH (MII-pH), HMII-pH, and laryngoscopy using the Hyodo scoring method from December 2016 to April 2019. The MII-pH and HMM-pH parameters were compared in the NIPs, whereas hypopharyngeal BI values were compared between NIPs with ≥ 5 and < 5 in Hyodo scores. Correlations between the hypopharyngeal BI values and the Hyodo score were analyzed using Spearman’s correlation coefficient. A receiver operator characteristic curve was created to determine the optimum cut-off of hypopharyngeal BI value to discriminate SD. Results: Three NIPs were diagnosed with pathological LPR and GERD by the HMII-pH monitoring. No significant differences in parameters were observed between MII-pH and HMII-pH monitoring. The correlation analysis demonstrated a significant negative correlation between the hypopharyngeal BI values and Hyodo scores. The optimal cutoff value for hypopharyngeal BI was 1552 Ω. Conclusions This study demonstrated the usefulness of HMII-pH monitoring in identifying NIP with pathological LPR. Considering the difficulties in performing examinations in NIPs, HMII-pH monitoring may be a potentially useful technique for the simultaneous evaluation of swallowing dysfunction, LPR, and GERD in NIP.
