Right atrial aneurysm is an extremity rare congenital heart defect. We report a case which was diagnosed during the early fetal stage and operated on in a 2 week old neonate. Following median sternotomy, aneurysmectomy was performed under a cardiopulmonary bypass. Histopathological examination of the resected atiral tissue showed a lipotomatous degeneration and reduction of the muscular elements. There were no postoperative complications.
Anomalous aortic origin of the left subclavian artery (LSCA) from the left pulmonary artery (LPA) is a rare congenital cardiac malformation. We describe a case of LSCA from the LPA via ductus arteriosus in association with a double-outlet right ventricle, which never has been reported previously in Korea.
In patients with subarterial ventricular septal defect (VSD), the progression of aortic regurgitation (AR) still remains unclear. This review is to identify the incidence of AR progression after VSD repair and to determine the optimal operation timing for subarterial VSD repair with or without aortic valve prolapse or AR. From January 2002 to December 2015, 103 patients who underwent subarterial VSD repair alone at our hospital were reviewed. All patients routinely underwent echocardiography (echo) performed by our pediatric cardiologists. The operative approach was through the pulmonary artery in all patients. The median age of patients at operation was 10 months (range 3 to 16.5 months). Eighty-nine patients (86.4%) underwent subarterial VSD closure before the age of 4 years. In the preoperative evaluation, 27.2% (28 patients) of the patients showed more than faint degree AR. The mean follow-up duration after VSD repair was 6.6 ± 4.0 years. In the latest follow-up echo after VSD repair, four patients had more than mild degree AR owing to aortic valve abnormalities or delayed operation period. Among them, AR progression occurred in only one patient (0.98%). Early and accurate assessment of the anatomical morphology of the aortic valve and optimal operation timing may be important to achieve better outcomes after repair and to prevent the development of aortic valve complications.
BackgroundMonocusp reconstruction with a transannular patch (TAP) results in early improvement because it relieves residual volume hypertension during the immediate postoperative period. However, few reports have assessed the long-term surgical outcomes of this procedure. The purpose of the present study was to evaluate the mid-term surgical outcomes of tetralogy of Fallot (TOF) repair using monocusp reconstruction with a TAP.MethodsBetween March 2000 and March 2009, 36 patients with a TOF received a TAP. A TAP with monocusp reconstruction (group I) was used in 25 patients and a TAP without monocusp reconstruction (group II) was used in 11 patients. We evaluated hemodynamic parameters using echocardiography during the follow-up period in both groups.ResultsAt the most recent follow-up echocardiography (mean follow-up, 8.2 years), the mean pulmonary valve velocities of the patients in group I and group II were 2.1±1.0 m/sec and 0.9±0.9 m/sec, respectively (p=0.001). Although the incidence of grade 3–4 pulmonary regurgitation (PR) was not significantly different between the two groups (group I: 16 patients, 64.0%; group II: 7 patients, 70.0%; p=0.735) during the follow-up period, the interval between the treatment and the incidence of PR aggravation was longer in group I than in group II (group I: 6.5±3.4 years; group II: 3.8±2.2 years; p=0.037).ConclusionMonocusp reconstruction with a TAP prolonged the interval between the initial treatment and grade 3–4 PR aggravation. Patients who received a TAP with monocusp reconstruction to repair TOF were not to progress to pulmonary stenosis during the follow-up period as those who received a TAP without monocusp reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
