rtifacts problematic in the synthetic FLAIR images using the current synMRI technique by adding long TE images and simple processing. Although further optimizations in data acquisition and processing techniques are required before actual clinical use, we expect our technique to become clinically useful.
Autologous pericardium is an ideal material for cardiovascular reconstruction including pulmonary artery plasty. Despite the fact that dehydration by ethanol has been used to improve its surgical handling, the effects of the ethanol on mechanical properties of the pericardium have not been previously investigated. The effects of short-duration ethanol dehydration on the mechanical properties of porcine pericardium were evaluated.

Porcine pericardia (n = 3) were separated into three groups the raw group with no treatments (RAW), the group immersed in 70% ethanol for 10 min (ET group), and the group immersed in 0.6% glutaraldehyde for 10 min (GA). We measured five parameters of mechanical properties as specified in ISO 7198.

ET treatment improved surgical handling as well as GA treatment. There were no significant differences in burst pressure (P = 0.639), suture retention strength (P = 0.529), ultimate tensile strength (UTS; P = 0.486), or Young's modulus (P = 0.408). Only the ultimate strain of the GA group was significantly higher among the three groups (RAW 33.34% ± 2.02%, ET 37.48% ± 1.84%, GA 44.74% ± 2.87%; P = 0.046).

Short-duration ethanol dehydration did not compromise its mechanical properties while maintaining its surgical handling improvements.

Sevabertinib A 61-year-old asymptomatic man was referred because of an abnormal shadow in the right lung field upon chest radiography. Computed tomography (CT) showed two well-demarcated tumors in the basal segment of the right lung. Twelve years previously, he underwent right adrenalectomy and was pathologically diagnosed as having a benign pheochromocytoma. Thereafter, he received a medical check-up annually. To confirm the diagnosis of two pulmonary tumors, video-assisted thoracic surgery was done and wedge resection of the right lower lobe completed. Pathology studies revealed these tumors as pulmonary metastases from the pheochromocytoma, which indicated that the true diagnosis was a malignant pheochromocytoma. Patients with a benign pheochromocytoma should continue to undergo careful monitoring for a long time after the initial surgical procedure. Thoracic surgeons should be aware of the possibility of pulmonary metastases even if >10 years have passed since initial resection of a benign pheochromocytoma.
Lead-induced tricuspid regurgitation (TR) after cardiac implantable electronic device (CIED) implantation is not fully understood. This study aimed to reveal the features of lead-induced TR by 3-dimensional echocardiography (3DE) in patients with heart failure (HF) events after CIED implantation.Methods and ResultsIn 143 patients, 3DE assessments for the tricuspid valve (TV) and right ventricular morphologies were sequentially performed within 3 days after CIED implantations, during TR exacerbations, and at ≥6 months after TR exacerbations. TR exacerbations were observed in 29 patients (median 10 months after CIED implantation, range 1-28 months), 15 of whom had lead-induced TR. In the 29 patients, the tenting height of the TV, tricuspid annular (TA) height, and TA area at baseline were independent predictors for worsening TR. In patients with lead-induced TR, tenting height of the TV and TA area were identified as the risk factors. In addition, all patients with a lead positioned on a leaflet immediately after CIED implantations developed lead-induced TR. At follow up, TR exacerbation of lead-induced TR persisted with TA remodeling, but it was improved in the lead non-related-TR group.

TA remodeling at baseline and a lead location on a leaflet immediately after CIED implantation were associated with lead-induced TR in patients with HF events after CIED implantation. Persistent TA remodeling may make lead-induced TR refractory against HF treatments.

The new guideline (NG) published by the Japanese Circulation Society (JCS) places emphasis on previous arrhythmic syncope and inducibility of ventricular fibrillation (VF) by ≤2 extrastimuli during programmed electrical stimulation (PES) for deciding the indication of an implantable cardioverter-defibrillator in patients with Brugada syndrome (BrS). This study evaluated the usefulness of the NG and compared it with the former guideline (FG) for risk stratification of patients with BrS.Methods and ResultsThis was a multicenter (7 Japanese hospitals) retrospective study involving 234 patients with BrS who underwent PES at baseline (226 males; mean age at diagnosis 44.9±13.4 years). At diagnosis, 46 patients (20%) had previous VF, 100 patients (43%) had previous syncope, and 88 patients (37%) were asymptomatic. We evaluated the difference in the incidence of VF in each indication according to the new and FGs. During the follow-up period (mean 6.9±5.2 years), the incidence of VF was higher in patients with Class IIa indication according to the NG (NG 16/45 patients [35.6%] vs. FG 16/104 patients [15.4%]), while the incidence of VF in patients with other than class I or IIa indication was similarly low in both guidelines (NG 2/143 patients [1.4%] vs. FG 2/84 patients [2.4%]).

This study validated the usefulness of the NG for risk stratification of BrS patients.

Therefore, it is necessary to consider adverse reactions of the drug at high doses as well as at lower doses after the indication has been expanded. Body mass index criteria for patients prescribed the drug in the real world tend to be applied less rigorously, which may increase the number of adverse reactions due to over-prescription. Liraglutide treatment was found effective and safe in some studies, while others have warned about its risks. Therefore, this review summarizes the current data available on side effects associated with liraglutide.
