Case reports of traumatic aortic regurgitation are rare. We report a case of a 62-year-old man injured by falling from a paraglider. After recovering from multiple injuries and discharge, he began to suffer from dyspnea. Severe aortic regurgitation and pseudoaneurysm of the sinus of Valsalva were diagnosed by ultrasound cardio graphy (UCG) and multi-detector-row computer tomography (MDCT). After cardiac failure was controlled, we operated. The commissure between the left and the right coronary cusps was detached from the aortic wall, and a modified Bentall operation was performed. The patient recovered well and was discharged uneventfully.

We surveyed the working environment, the degree of satisfaction and the educational methods targeting under forty congenital cardiac surgeons in Japan. We herein report the results of this survey. Summary of this work was presented at the 2018 CHSS Japan Congress, Tokyo, Japan.

Basic procedures that cardiovascular surgeons routinely perform are rarely discussed, despite the great variability among facilities. We conducted a questionnaire survey on Extracorporeal Membrane Oxygenation (ECMO) targeting under-forty cardiovascular surgeons and obtained responses from 53 surgeons. We report the questionnaire results.

BACKGROUND/AIMS:: While the occurrence of multiple whitish flat elevated lesions (MWFL) was first reported in 2007, no studies on MWFL have been published to date. The present retrospective observational study aimed to clarify the endoscopic findings and clinicopathological features of MWFL. METHODS:: Subjects were consecutive patients who underwent upper gastrointestinal endoscopy as part of routine screening between April 2014 and March 2015. The conventional white-light, non-magnifying and magnifying narrow-band images were reviewed. Clinical features were compared between patients with and without MWFL. RESULTS:: The conventional endoscopic findings of MWFL include multiple whitish, flat, and slightly elevated lesions of various sizes, mainly located in the gastric body and fundus. Narrow-band imaging enhanced the contrast of MWFL and background mucosa, and magnifying narrow-band imaging depicted a uniformly long, narrow, and elliptical marginal crypt epithelium with an unclear microvascular pattern. Histopathological findings revealed hyperplastic changes of the foveolar epithelium, and parietal cell protrusions and oxyntic gland dilatations were observed in the fundic glands, without any intestinal metaplasia. The rate of acid-reducing drug use was significantly higher in patients with MWFL than in those without (100% [13/13] vs. 53.7% [88/164], p < 0.001). CONCLUSIONS:: The present study indicated a relationship between the presence and endoscopic features of MWFL and history of acidreducing drug use.
