A one-month-old baby boy with a complete atrioventricular septal defect underwent pulmonary artery banding. A high take-off of the left coronary artery, overlooked on the echocardiogram, was identified. It was compressed by the right pulmonary artery that was dilated owing to pulmonary artery banding. The patient developed severe heart failure, and a Lecompte maneuver was performed. The procedure helped effectively treat this congenital heart disease with a high take-off coronary artery compressed by the right pulmonary artery.

This is the first report of total arch replacement to repair re-coarctation. A 14-year-old boy with hypoplastic left heart syndrome developed re-coarctation, severe stenosis of neck vessels, and right ventricle dysfunction after a Norwood procedure. We performed total arch replacement; the postoperative course was unremarkable. He was followed up until 18 years of age and did not need re-intervention. Using artificial blood vessels in total arch replacement is rarely indicated but can be safely achieved when required. Mismatch between patient and graft size may be an issue in the future.

Background: No study has examined the association of the calcification of abdominal artery orifices with nonocclusive mesenteric ischemia (NOMI) in dialysis patients undergoing cardiac surgery. Thus, this study aimed to determine whether calcification of abdominal blood vessel orifices in hemodialysis patients may be a risk factor for NOMI and examine the long-term survival of dialysis patients after undergoing cardiac surgery.Methods: From April 2014 to September 2020, 100 dialysis patients underwent cardiac surgery at our hospital. The calcification of the celiac artery (CA) and superior mesenteric artery (SMA) was evaluated by computed tomography, and the degree of orifice stenosis was graded as follows: patent, 0; partial occlusion, 1; and complete occlusion, 2.Results: Eight patients experienced NOMI, and all of them died. SMA calcification scores were not significantly different between the NOMI and non-NOMI groups (1.38±0.52 vs. 1.13±0.69; P = 0.247). However, the average CA orifice calcification score was significantly greater in the NOMI group than in the non-NOMI group (1.63±0.52 vs. 1.15±0.65; P = 0.039), and the SMA+CA orifice calcification scores were significantly different between the groups (3.00±0.76 vs. [non-NOMI] 2.25±1.18; P = 0.028). In all patients, the 30-day and in-hospital mortality rates were 13% and 18%, respectively. All patients were completely followed up with a mean follow-up period of 604±585 days. Kaplan–Meier survival curves showed that patients with SMA and CA calcification tended to have a shorter overall survival than patients without calcification; however, no significant difference was noted.Conclusions: The calcification of CA and/or SMA orifices was associated with postoperative NOMI and poor long-term survival among dialysis patients undergoing cardiac surgery.

Management of tricuspid regurgitation( TR) before right ventricular dysfunction is critical in patients with hypoplastic left heart syndrome (HLHS);however, appropriate tricuspid valvuloplasty (TVP) is challenging. We report a TVP technique for TR in a 4-year-old girl with HLHS, who had undergone Norwood operation, bidirectional cavopulmonary shunt, and TVP. Preoperative echocardiography revealed the etiology of TR as anterior leaflet prolapse, annulus dilatation, and relative tethering of the septal leaflet. We performed surgical reconstruction of the anterior leaflet with artificial chordae. Before annuloplasty, the posterior leaflet and a part of the septal leaflet were detached from the annulus with a 1 mm margin using the Key-Reed technique. Furthermore, the posterior leaflet was slid to augment the septal leaflet. We managed to regulate the TR by enlarging the septal leaflet, thus increasing the coaptation zone. We believe that this technique will be useful for TR with annulus dilatation in HLHS.

Abstract

Surgical treatment is challenging in pediatric patients with left ventricular outflow tract (LVOT) stenosis (LVOTS). We herein present the case of a 2-year-old male patient with porencephaly who was diagnosed with LVOTS accompanied by moderate mitral valve regurgitation (MR) with systolic anterior motion (SAM). Edge-to-edge mitral valve reconstruction and myectomy of the abnormal cardiac muscle were performed, with an uneventful postoperative course. LVOT myectomy and edge-to-edge mitral valve repair may be considered as a safe and acceptable approach with good clinical outcomes in pediatric patients with LVOTS accompanied by MR with SAM.

Abstract

A Kommerell’s diverticulum is a rare congenital aortic arch anomaly associated with a high rate of aortic rupture or dissection. Therefore, surgical or endovascular repair should be considered early. A 64-year-old man was incidentally found to have an aortic arch anomaly, Kommerell’s diverticulum, with a right aberrant subclavian artery and distal arch aneurysm. Hybrid total arch replacement with bilateral extra-anatomical axillary artery bypass and frozen elephant trunk technique was performed. This particular surgical approach would be a treatment option for any type of Kommerell’s diverticulum.

症例は80歳，女性。1ヵ月間程度持続する左下腹部痛を主訴に当科紹介受診。来院時，左下腹部に限局性圧痛と筋性防御を認めた。腹部造影CTで横行結腸近傍の大網内に4cm長の線状高吸収領域を伴う5cm大の膿瘍を疑う腫瘤を認めた。下腹部痛が出現する数日前に鮭骨を誤飲した病歴があり，魚骨による消化管穿孔に続発した腹腔内膿瘍と診断し，緊急手術を施行した。単孔式腹腔鏡下に横行結腸に隣接した大網腫瘤を摘除した。腫瘤周囲の横行結腸漿膜に発赤と一部びらんを認めたが明らかな穿孔部位は同定できなかった。病理組織学的所見は大網に高度の好中球浸潤や壊死を認め，膿瘍内に4cm長の魚骨を認めた。魚骨による腹腔内膿瘍は穿孔や穿通部位が不明瞭な場合も散見されるが，術前CTである程度部位の同定が可能であり，近年普及してきている単孔式腹腔鏡手術も治療の選択肢になり得ると考えられた。
