RESUMO

BACKGROUND: Tetralogy of Fallot is a congenital heart disease mostly diagnosed and treated in early childhood. However, there are some adult cases receiving treatment. CASE PRESENTATION: We describe a 78-year-old Japanese woman who presented with severely hypertrophic right ventricle, ventricular septum defect, overriding aorta, and severe infundibular stenosis in the right ventricular outflow tract. As hypoxemia was mild and daily exertion was sufficiently possible, home oxygen therapy was introduced. After 1 month, she was referred because of a positive blood culture. The blood culture test was positive four times, therefore, the antibacterial drug was administered according to active infective endocarditis. SpO2 repeatedly decreased during hospitalization, thus oxygen was needed. As there were infective endocarditis onset and progressive hypoxemia, we planned a surgical correction. CONCLUSION: Tetralogy of Fallot was diagnosed and successfully treated with complete surgical correction, and the development of infective endocarditis was the definitive indication for surgery at this late age.

RESUMO

This study aimed to evaluate the anatomical reproducibility of a preoperative intracardiac 3D image (IC image) created using computed tomography, and to investigate its usefulness as a surgical decision-making tool. Between 2012 and 2022, ventricular septal defect (VSD) patients, and double outlet right ventricle (DORV) or transposition of the great arteries (TGA) with pulmonary stenosis (PS) patients who underwent cardiac surgery and had preoperative computed tomography were enrolled. SYNAPSE VINCENT® (Fujifilm) was used to create an IC image which was analyzed retrospectively. In 14 VSD patients, the diagnostic consistency rate in the Soto classification with intraoperative findings was 100% (14/14) for IC image versus 64% (9/14) for transthoracic echocardiography (P = 0.04). The defect size showed a higher correlation coefficient with IC image (0.837, P = 0.001) than with transthoracic echocardiography (0.567, P = 0.034). In 11 DORV/TGA with PS patients, the diagnostic consistency rate in the Lev classification was 100% (9/9) for IC image versus 77% (7/9) for transthoracic echocardiography (P = 0.47). The secondary interventricular foramen (SVF)/left ventricular outflow tract (LVOT) ratio by IC image was significantly smaller in the biventricular-repair group (median 0.71, IQR 0.67-1.06) than in the univentricular-repair group (median 1.79, IQR 1.53-2.42) (P = 0.006). An IC image is useful as a surgical decision-making tool for simple VSDs and complex congenital heart diseases such as DORV or TGA with pulmonary stenosis. The SVF/LVOT ratio determined from the IC image may be a useful indicator for avoiding LVOT obstruction.

RESUMO

Tetralogy of Fallot was repaired previously in a preschooler through right ventriculotomy, providing excellent exposure for ventricular septal defect closure and right ventricular outflow tract obstruction relief. Herein, we describe the preschooler as a 50-year-old man with untreated atrial septal defect found at pulmonary valve replacement in the remote period after tetralogy of Fallot repair. It was inferred intraoperatively that the previous tetralogy of Fallot was repaired only through right ventriculotomy, and atrial septal defect closure was performed together with pulmonary valve replacement.

RESUMO

BACKGROUND: Mortality rates after the arterial switch operation (ASO) for transposition of the great arteries (TGA) are still suboptimal mainly due to postoperative myocardial ischemia. The present study aimed to investigate the clinical impact of our modification of coronary transfer technique, wherein the coronary cuffs are transferred oblique to the pulmonary trunk to avoid torsion of the coronary arteries. METHODS: From September 2010 to August 2020, all 37 consecutive patients who underwent ASO for TGA with our modification, that is, the oblique coronary transfer technique, were retrospectively reviewed. Cardiac dimensions and patency of the coronary arteries were examined by cineangiography, and hemodynamic parameters were measured by cardiac catheterization and transthoracic echocardiography. RESULTS: During a median 5.3 years of postoperative follow-up, there were no deaths and no patient required mechanical circulatory support. Median left ventricular ejection fraction was 68.8% (interquartile range 66.8-71.0, minimum 54.6). All patients maintained normal sinus rhythm without arrhythmia, except in the early postoperative period. Five patients underwent unplanned re-intervention for peripheral pulmonary stenosis, but none for coronary insufficiency. The 8-year freedom from re-intervention rate was 85.6%. Among a total of 110 transplanted coronary arteries, 108 (98.2%) remained patent, and two circumflex arteries were occluded much later after surgery, although with preserved ventricular function due to compensatory growth of other coronary branches. CONCLUSION: The oblique coronary transfer technique, which aims to avoid torsion of the coronary arteries, provides good patency of the coronary arteries and subsequent improvement of postoperative mortality rates following ASO.

RESUMO

Although De Vega annuloplasty is an important option for pediatric patients with functional tricuspid regurgitation (TR), little is known about its long-term results, including the future of the plicated annulus. We retrospectively reviewed our experience with pediatric patients who underwent the De Vega annuloplasty between 2005 and 2020. Tricuspid valve assessments were performed by transthoracic echocardiography. The targeted diameter of annular plication was 80 to 90% of normal tricuspid diameter, according to the patient's condition. The study included 55 patients (41 with biventricular physiology (group B), 14 with univentricular physiology (group U)) with a median follow-up of 5.0 years. Median age at operation was 5.0 years. There was one late death due to severe mitral regurgitation. Tricuspid valve reoperation was required in five patients and the 10-year freedom from reoperation was 91.9% for the entire cohort. The 10-year freedom from the composite adverse outcome of death, reoperation, and significant TR was 79.2% in group B versus 56.6% in group U (p = 0.034). TR grade significantly decreased after surgery (p < 0.001), without significant aggravation during the postoperative follow-up. No patients presented tricuspid stenosis. Mean Z-scores of annular diameter immediately after operation and at the latest follow-up were - 0.65 ± 0.56 versus - 0.47 ± 0.65 (p = 0.57). De Vega annuloplasty is a safe, efficient, and durable procedure for functional TR in pediatric patients including those with univentricular physiology, allowing adequate growth of the plicated annulus without the progression of tricuspid stenosis.

RESUMO

Two infants with congenital heart disease developed life-threatening airway obstruction due to progressive dilatation of the aorta. Both underwent posterior aortic plication with extracorporeal bypass (9 and 4 months of age). After surgery, the arterial diameter was adequately reduced with a smooth aortic route leading to a wide airway space. Both patients were weaned from the ventilator shortly after surgery and are currently asymptomatic.

RESUMO

BACKGROUND: Good syndrome is a rare condition, manifesting as immunodeficiency due to hypogammaglobulinemia associated with thymoma. Herein, we present a patient with Good syndrome whose thymoma was resected after treatment of cytomegalovirus hepatitis. CASE PRESENTATION: The patient was a 45-year-old woman presenting with fever, cough, and nasal discharge, and was diagnosed with thymoma and hypogammaglobulinemia. She subsequently developed cytomegalovirus hepatitis that was treated by immunoglobulin. After resolution of the hepatitis, she underwent thymectomy through a left anterior thoracotomy. Her postoperative course was uneventful, and while receiving ongoing immunoglobulin therapy, she has been doing well without signs of infection. CONCLUSIONS: Management of infections is important for patients with Good syndrome. To minimize the risk of perioperative infection, we should take care while planning the surgical approach and procedure.

RESUMO

A 5-year-old girl has a history of epicardial VVI-pacemaker implantation due to congenital heart block at the age of 2 months. Five years later, she developed heart failure at the same time of battery depletion. The chest X-ray indicated the loop formation of the epicardial leads and the echocardiogram demonstrated paradoxical movement of ventricles. The 3-dimensional computed tomography finally revealed strangulation of biventricular apex caused by loop of the leads. She underwent reoperation. Cardiac strangulation was relieved by total removal of the loop and repositioning of right atrial and ventricular electrodes in a gentle curve of the leads. She was discharged and doing well. Cardiac strangulation is a rare, but it can be lethal. Therefore epicardial pacemaker leads should not be positioned around the ventricle with excessive redundancy.
