Retrospective review of the congenital coronary artery (CA) anomalies detected by a 64-slice multidetector row computed tomographic (MDCT) angiography. The type of the anomaly, imaging characteristics, clinical relevance and the superiority of the MDCT over conventional coronary angiography are discussed. Multidetector row computed tomographic coronary angiography was carried out by the usual technique with 70 cc of non-ionic contrast agent and retrospective electrocardiogram gating. The volume data obtained were reconstructed in axial plane, along with volume-rendered three-dimensional reconstruction and virtual angioscopy in selected patients. The images were analysed by a radiologist, experienced in cardiac CT, and an experienced cardiologist. A retrospective review of the records was carried out, and subjects with congenital coronary anomalies were included in the study. Between 15 November 2005 and 27 February 2007, 1495 MDCT coronary angiograms were carried out. Eleven of them were found to have coronary anomalies. Five had absent left main CA. Two had interarterial course of the left main CA artery passing in between the right ventricular outflow tract and the root of aorta. In one patient, there was aberrant origin of right CA from the left aortic sinus with subsequent interarterial course and another one had aberrant origin of circumflex artery from the right aortic sinus. One patient each of congenitally absent circumflex artery and atresia of the right CA were found. Sixty-four slice MDCT coronary angiography provided accurate depiction of anomalous vessel origin and course along with the complex anatomical relation with the adjacent structures. CT can be considered as a first-line imaging method for delineating coronary arterial anomalies.
Between June 1999 and September 2002, 45 patients (age, 34 +/- 13 years; mean shunt ratio, 2.6 +/- 0.6) underwent transcatheter atrial septal defect (ASD) closure at our institution with the Amplatzer septal occluder (mean device size, 31.4 +/- 3 mm). Patients were selected by transesophageal echocardiography. The mean ASD dimension was 25.3 +/- 3.7 mm and 33 (73%) patients had deficient anterior rim. Specific procedural details included the use of 13 or 14 Fr introducer sheaths and the right upper pulmonary vein approach if the conventional approach failed. There were two procedural failures, with device embolization in both (surgical retrieval in one, catheter retrieval in one). During follow-up (3-30 months; median, 16 months), one patient (59 years) with previous atrial flutter had pulmonary embolism and was managed with anticoagulation. Two patients developed symptomatic atrial flutter. Fluoroscopy time was 31.6 +/- 19.5 min for the first 22 cases and 19.6 +/- 11.4 min for the rest (P = 0.04). Transcatheter closure of large ASDs is technically feasible but careful long-term follow-up is needed to document its safety.
Background:Management of native uncomplicated coarctation in neonates remains controversial with current evidence favoring surgery. The logistics of organizing surgical repair at short notice in sick infants with critical coarctation can be challenging.Methods and Results:We reviewed data of 10 infants (mean age of 2.9 ±1.6 weeks) who underwent catheter intervention for severe coarctation and left ventricular (LV) dysfunction between July 2003 and August 2007. Additional cardiac lesions were present in 7. Mean systolic gradient declined from 51±12 mm Hg to 8.7±6.7 mm Hg after dilation. The coarctation segment was stented in five patients. Procedural success was achieved in all patients with no mortality. Complications included brief cardiopulmonary arrest (n =1), sepsis (n = 1) and temporary pulse loss (n = 2). LV dysfunction improved in all patients. Average ICU stay was 5±3.4 days and hospital stay was 6.5±3.4 days. On follow-up (14.1±10.5 months), all developed restenosis after median period of 12 weeks (range four to 28 weeks). Three (two with stents) underwent elective coarctation repair, two underwent ventricular septal defect (VSD) closure and coarctation repair and one underwent pulmonary artery (PA) banding. Two patients who developed restenosis on follow-up were advised surgery, but did not report. Two (one with stent) underwent redilatation and are being followed with no significant residual gradients.Conclusion:Balloon dilation ± stenting is an effective interim palliation for infants and newborns with critical coarctation and LV dysfunction. Restenosis is inevitable and requires to be addressed.
Coil occlusion of patent ductus arteriosus (PDA), although inexpensive, is technically challenging for the moderate-large ducts in small children. Bioptome assistance allows better control and precision. We describe case selection strategies, technique, immediate and short-term results of bioptome-assisted closure of moderate-large (>/= 3 mm) PDA in 86 infants and children = 10 kg (age, 18 days to 3 years; median, 8 months; weight, 6.6 +/- 1.9 kg; duct size, 3.6 +/- 0.8 mm; pulmonary artery mean pressures, 33 +/- 12 mm Hg). Patients with PDA > 6 mm (> 4 mm for children under 5 kg) and/or shallow ampullae (by echocardiography) underwent operation (n = 41). Specific technical modifications included use of long sheaths (5.5-8 Fr) for duct delineation and coil delivery, cutting of coils turns (51 patients) to accommodate the coils in the ampulla, and simultaneous delivery of multiple coils (n = 43). As far as possible, coils were deployed entirely in the ampulla. Median fluoroscopy time was 7.3 min (1.2-42 min). Successful deployment was feasible in all (final pulmonary artery mean pressures, 20 +/- 4.6 mm Hg). Coils embolized in 14 (16%) patients (all retrieved). Complete occlusion occurred immediately in 63 patients (73%) and in 77 patients (89%) at 24 hr. Three patients had new gradients in the left pulmonary artery. Follow-up (62 patients; median duration, 13 months) revealed small residual Doppler flows in 11 patients (18%) at the most recent visit. Bioptome-assisted coil occlusion of moderate-large PDA in selected infants and small children is feasible with encouraging results.
Eventration of the diaphragm, most often an isolated entity and detected incidentally, has been known to be associated with several genetic syndromes. Authors report their experience of seeing diaphragmatic eventration in association with Poland syndrome and wandering spleen syndrome and briefly discuss the literature.
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.
