Structural examination of human heart specimens at the microscopic level is a prerequisite for understanding congenital diseases. It desirable not to destroy or alter properties such because their scarcity. However, many currently available imaging techniques either specimen through sectioning chemical and mechanical staining contrast agent injection. As result, subsequent studies may be possible. X-ray phase-contrast tomography an modality biological soft tissues that does specimen. The...
Background: The feasibility of synchrotron radiation-based phase-contrast computed tomography (PCCT) for visualization the atrioventricular (AV) conduction axis in human whole heart specimens was tested using four postmortem structurally normal newborn hearts obtained at autopsy. Methods: A PCCT imaging system beamline BL20B2 a SPring-8 radiation facility used. performed with “virtual” slicing three-dimensional reconstructed images. For histological verification, were cut into planes similar...
Abstract Background Anomalous left coronary artery from the pulmonary (ALCAPA) is a rare congenital anomaly that results in high mortality if untreated. Our aim was to extend our knowledge of histological, angiographic, and clinical characteristics ALCAPA order deepen understanding this entity. Case presentation We were involved assessment, treatment, pathological evaluation two adult patients who rescued ventricular fibrillation then surgically treated establish dual system. Histological...
Reoperation in cardiac surgery is associated with increased risk due to surgical adhesions. Application of a bioresorbable material could theoretically reduce adhesions and allow later development free dissection plane for reoperation. Twenty-one patients whom hyaluronic acid-carboxymethylcellulose adhesion barrier had been applied preceding underwent reoperations, while 23 reoperations during the same period without prior barrier. Blinded observers graded tenacity from video recordings...
Pharmacokinetic (PK) parameters can change significantly during extracorporeal membrane oxygenation (ECMO) and continuous haemodialysis. This case report describes the pharmacokinetics of a 3-h meropenem infusion in an infantile anuric patient on ECMO with haemodialysis.A 19-month-old female asplenia syndrome was admitted to paediatric intensive care unit for postoperative management extracardiac total cavopulmonary connection procedure. Veno-arterial haemodialysis were initiated Day 2...
The location of the atrioventricular conduction axis in setting septal defect has previously been shown by histology and intraoperative recordings. We have now reassessed arrangement using phase-contrast computed tomography, aiming to provide precise measurements so as optimize future surgical repairs. used system based on an X-ray Talbot grating interferometer beamline BL20B2 a SPring-8 synchrotron radiation facility available Japan. analyzed 18 specimens. node was found within nodal...
To visualize and quantify the atrioventricular conduction axis in setting of ventricular septal defect using phase contrast computed tomography.We used SPring-8 synchrotron radiation facility Hyogo prefecture Japan, processing reconstructing data with 3-dimensional software.We studied 8 hearts obtained from patients known to have had defects, aged 6 150 days, a median 24.5 days. None individuals, however, undergone corrective surgery. The penetrating bundle was found at 1.43 mm crest, range...
Surgical intervention for HB with tumor thrombi extending into the IVC and RA might requires careful planning of surgical procedures, including vascular reconstruction extracorporeal circulation. We herein report a successful case LDLT atrial extension thrombus by circulation transdiaphragmatic approach. The patient was 5-year-old boy PRETEXT IV that extended RA. After 4 cycles chemotherapy resection bilateral lung metastases, size primary decreased. As from LHV to had decreased but still...
An 1186-g infant was born at 27 weeks’ gestation. Echocardiography showed critical aortic stenosis, a dilated left ventricle (left ventricular end-diastolic diameter, 16.9 mm), and poor function ejection fraction, 8.5%). Due to duct-dependent systemic circulation, the patient underwent hybrid intervention consisting of bilateral pulmonary artery banding (PAB) balloon valvuloplasty (BAV) via ascending aorta on day 2. A stainless steel tip 6-French introducer were combined create an access...
To assess the correlations between interventricular mechanical delay (IVMD) and cardiac function in children with isolated complete atrioventricular block epicardial pacing.We enrolled 13 (six boys) an dual-chamber pacemaker due to or advanced block. The patients were 9.8 (range, 6.8-15.3) years old, none had symptomatic heart failure at follow-up visit. Ventricular pacing sites, which remained same for 7.2 (1.6-12.3) years, left ventricle (LV) two patients, right (RV) four both ventricles...
Postoperative pleural effusion (PE) is common after pediatric cardiac surgery, and if prolonged can lead to the deterioration of general condition due malnutrition result in death. This study aims at identifying prognostic factors PE surgery.Design settings: Patients were divided into effective (with chest tube removal within 10 days medical therapy) ineffective place for more than days) groups. The compared between two groups retrospectively.Participants included patients who had surgery...
Surgical management of truncus arteriosus, or common arterial trunk, has expanded over the past three decades to include earlier surgical intervention, initially during infancy and now chiefly in neonatal period. Many studies have shown that preoperative truncal valve insufficiency is an independent risk factor for mortality. We herein present case a five-month-old boy with severe who underwent repair trunk prosthetic replacement associated annular enlargement after initial stabilization...
Abstract We aimed to elucidate the relationship between severity of secondary mitral regurgitation and valve geometry in children with dilated cardiomyopathy. The medical records 16 cardiomyopathy (median age, 1.2 years; range, 0.4–12.3 years) were reviewed. Mitral was evaluated by measuring coaptation depth using echocardiographic apical four-chamber views at initial presentation. Patients dichotomised according severity: patients moderate or severe (n=6) those mild (n=10). A total 58...
特発性拡張型心筋症の診断で，心不全症状が内科的治療に不応で進行性であった7か月乳児に対し，在宅管理を目標に，過去に有効性が報告されている肺動脈絞扼術を施行した．心不全症状の進行は緩徐になったが，回復するまでには至らず入院は継続され，術後1年2か月後にExcor®を装着し，心臓移植待機中である．肺動脈絞扼術後に右室機能が低下したことが，回復しなかった一因であると推測される．適切な患者背景や絞扼条件が確立できれば，肺動脈絞扼術は乳児拡張型心筋症に対する心不全治療の一つの選択肢になり，患者家族の負担軽減，医療費の低減，医療の均てん化に貢献できる可能性がある．
Aberrant right subclavian artery (ARSA)-esophageal fistula has rarely been reported but fatal outcomes in most cases. We report a 10-year-old girl who presented with massive hematemesis during recovery from head injury caused by motor vehicle accident. Prompt detection of the esophageal bleeding point esophagoscopy followed balloon tamponade led to temporary hemostasis, which time an emergency operation was prepared and started promptly. Two-staged surgery performed successful outcome;...
