When performing aortic valve replacement in young patients, mechanical valves are recommended due to their durability. However, because mechanical valves require lifelong use of warfarin and carry risks such as easy bleeding, bioprosthetic valve replacement may be performed in some cases even in young patients. In this report, we describe a case of a patient who underwent bioprosthetic aortic valve replacement with aortic annular enlargement in anticipation of TAV in SAV and had a good postoperative course. The patient is a 51-year-old male. He was referred to our hospital for surgical treatment of severe aortic stenosis. The patient strongly preferred a bioprosthetic valve due to the disadvantage of taking warfarin. Therefore, we considered the possibility of TAV in SAV due to his young age, and decided to perform aortic annular enlargement if necessary. Intraoperatively, after resection and decalcification of the valve, a sizer was inserted, but the 19 mm sizer could not pass through, so we decided to perform aortic annular enlargement. Aortic annular enlargement was performed by suturing a Dacron patch and implantation of a 23 mm bioprosthetic valve. The patient had no major postoperative problems and was discharged home on the 14th day after surgery. In order to avoid PPM in the future when TAVI is performed, aortic annular enlargement should be considered in young patients undergoing aortic valve replacement using a bioprosthetic valve if TAV in SAV is considered to be difficult.

Background/Aims: The Heart Failure Association (HFA)-PEFF score is recognized as a simple method to diagnose heart failure (HF) with preserved ejection fraction (HFpEF). This study aimed to evaluate the relationship between HFA-PEFF scores and cardiovascular outcomes in HFpEF patients. Methods: A total of 502 consecutive HFpEF patients were prospectively observed for up to 1,500 days. Cardiovascular outcomes were compared between two groups of patients, defined by their HFA-PEFF scores: those who scored 2–4 (the intermediate-score group) and those who scored 5–6 group (the high-score group). Overall, 236 cardiovascular events were observed during the follow-up period (median, 1,159 days). Results: Kaplan-Meier analysis showed that there were significant differences in composite cardiovascular events and HF-related events between the intermediate-score group and the high-score group (p = 0.003 and p < 0.001, respectively). Multivariate Cox proportional hazards analysis showed that the HFA-PEFF scores significantly predicted future HF-related events (hazard ratio, 1.66; 95% confidence interval [CI], 1.11 to 2.50; p = 0.014); receiver operating characteristic analysis confirmed this relationship (area under the curve, 0.633; 95% CI, 0.574 to 0.692; p < 0.001). The cutoff HFA-PEFF score for the identification of HF-related events was 4.5. Decision curve analysis revealed that combining the HFA-PEFF score with conventional prognostic factors improved the prediction of HF-related events. Conclusions HFA-PEFF scores may be useful for predicting HF-related events in HFpEF patients.

Pericardial pacing wire placement may occasionally result in intravascular or intratracheal wire migration, infective endocarditis, and sepsis; reportedly, the incidence of complications is approximately 0.09 to 0.4%. We report a case of a retained epicardial pacing wire that migrated into the pulmonary artery. A 66-year-old man underwent coronary artery bypass grafting for angina pectoris, with placement of an epicardial pacing wire on the right ventricular epicardium, 6 years prior to presentation. Some resistance was encountered during wire extraction; therefore, it was cut off at the cutaneous level on postoperative day 8. Computed tomography performed 6 years postoperatively revealed migration of the pacing wire into the pulmonary artery, and it was removed using catheter intervention. Surgeons should be aware of complications associated with retained pacing wires in patients in whom epicardial wires are retained after cardiac surgery.

In the U-40 column, we conducted a questionnaire survey of the U-40 generation on the theme of the specialist system for cardiovascular surgery and reported on the present condition and problems in obtaining certification. With the introduction of a new system, off the job training and participatory training using extracorporeal circulation techniques were newly mandated. In this article, we report the results and discussion of the questionnaire survey regarding the present condition of extracorporeal circulation training for the U-40 generation and the pros and cons of training programs.

We investigated how cardiovascular surgeons get a day off.

We report two cases with postoperative sternal osteomyelitis after coronary artery bypass graft (CABG), in whom successful two-stage reconstruction was performed via negative pressure wound therapy (NPWT) and pectoralis major myocutaneous flaps. Two patients underwent CABG using bilateral internal thoracic arteries, after which they had surgical site infection (SSI). The intractable wound did not heal with irrigation and NPWT. Then, sternal osteomyelitis was observed via magnetic resonance imaging (MRI), so we planned two-stage reconstruction. The first stage of treatment consisted of complete debridement (including removal of sternal wires and necrosectomy of soft tissue and sequestrum) and application of NPWT until the remission of inflammation. The second stage consisted of wound closure with pectoralis major myocutaneous advancement flaps. After wound closure, the two patients were given 2 months of oral antibiotics, and the postoperative results were good. Two-stage reconstruction with NPWT and pectoralis major myocutaneous flaps results in excellent clinical outcome. In the first stage, the key to the successful management of postoperative sternal osteomyelitis is infection control. This includes surgical debridement and wound-bed preparation with NPWT. The pectoralis major myocutaneous flap technique is brief and does not require a second cutaneous incision or an intact internal thoracic artery. In conclusion, the pectoralis major myocutaneous flap is a useful option in two-stage reconstruction after CABG.

We report two cases of total arch replacement with open stent graft for the aberrant right subclavian artery (ARSA). Case 1 was a thoracic artery aneurysm with an ARSA. We thought it would be difficult to perform in-situ reconstruction of ARSA via median sternotomy, so we performed total arch replacement with the open stent-grafting technique. Therefore the right axillary artery was reconstructed by extra-anatomical bypass and coil embolization of the ARSA proximal to the vertebral artery to achieve complete thrombosis of the ARSA. The postoperative course was uneventful. Case 2 was a Stanford type A acute aortic dissection involving an ARSA with the entry located near the ARSA. Total arch replacement was performed using the open stent-grafting technique to close the entry site and origin of the ARSA. Then the right axillary artery was reconstructed by extra-anatomical bypass and coil embolization of the ARSA. The postoperative course was uneventful. The open stent-grafting technique might be an effective alternative management of thoracic aortic disease with ARSA.

A 71-year-old man underwent a medical checkup at another hospital with principal complaint of chest discomfort, and was diagnosed by computed tomography (CT) to have a left subclavian artery aneurysm. The CT revealed a 33-mm saccular aneurysm that was located at the proximal portion of the left subclavian artery. Because of the high risk of surgery, we planned to insert a stent graft into the left subclavian artery. We could not avoid occluding the ostium of the left vertebral artery with commercially-available stent grafts, and so decided to insert a surgeon-modified stent graft, in which the fabric of the distal portion of the stent graft was stripped away. The surgeon-modified stent graft was inserted from the conduit of the left axillary artery. Postoperative course was uneventful and the postoperative examination confirmed complete exclusion of the aneurysm and patency of the left vertebral artery.

BACKGROUND/AIMS: We applied a back light system (BLS) with a magnifying glass to improve the ability to assess the adequacy of specimen sampling using endosonography. We conducted this study to evaluate the efficacy of the BLS in sampling of specimens by endoscopic ultrasound-guided fine needle aspiration of solid pancreatic masses. METHODS: This was a prospective, randomized, crossover, single-center clinical trial. An endosonographer evaluated adequacy on gross visual inspection and identified whitish specimen sampling sites with and without the BLS according to a randomization sequence in the first and second passes with a 25-G needle. On cytological evaluation, the presence of well-defined pancreatic ductal epithelium was evaluated by a cytopathologist who was blinded to any clinical information. RESULTS: A total of 80 consecutive patients were eligible during the study period. Adequacy was observed for 52 specimens (65%) with the BLS and 54 (68%) without the BLS (p=0.88). In assessment of specimen adequacy on gross examination, only fair agreement was observed both with and without BLS (kappa score 0.40 and 0.29, respectively). CONCLUSIONS: The BLS did not influence the ability to identify specimen sampling sites or reliable assessment of specimen site adequacy using gross visual inspection.

BACKGROUND/AIMS: Groove pancreatitis (GP) is an uncommon disease involving the pancreaticoduodenal area. Possible pathogenesis includes obstructive pancreatitis in the duct of Santorini and impaired communication with the duct of Wirsung, minor papilla stenosis, and leakage causing inflammation. Limited data regarding endoscopic treatment have been published. METHODS: Seven patients with GP receiving endoscopic treatment were reviewed. The morphology of the pancreatic duct was evaluated by a pancreatogram. Endoscopic dilation of the minor papilla and drainage of the duct of Santorini were performed. RESULTS: There were two pancreatic divisum cases, one ansa pancreatica case and four impaired connections between the duct of Santorini and the main pancreatic duct. Three to 31 sessions of endoscopy, with 2 to 24 sessions of transpapillary stenting and dilation, were performed. Interventions through the minor papilla were successfully performed in six of seven cases. The pancreatic stenting duration ranged from 2 to 87 months. Five patients with evidence of chronic pancreatitis (CP) tended to receive more endoscopic interventions than did the two patients without CP (2–24 vs 2, respectively) for GP and other complications associated with CP. CONCLUSIONS: Disconnection or impairment of communication between the ducts of Santorini and Wirsung was observed in all cases of GP. No surgery was required, and endoscopic minor papilla dilation and drainage of the duct of Santorini were feasible for the treatment of GP.
