Wolff Parkinson White Syndrome

AbstractCoexistence of atrioventricular block and Wolff-Parkinson-White syndrome is uncommon, but may occur in children, particularly with certain congenital heart defects. Our study describes 5 children who had pre-excitation and underlying disturbance of atrioventricular conduction. All of these patients had structural heart defects, consisting of discordant atrioventricular connections in three, double inlet left ventricle in one, and a ventricular septal defect associated with straddling of the tricuspid valve in the other. In 4 of the patients, the presence of atrioventricular block was initially masked by the pre-excitation. When the conduction through an accessory pathway is lost, the child may be left with atrioventricular block, which is poorly tolerated in the setting of complex cardiac anatomy. Awareness of this association of Wolff-Parkinson-White syndrome and atrioventricular block is important in understanding the natural history and the management of children with congenital heart defects that are associated with tenuous atrioventricular conduction.

Wolff Parkinson White Syndrome

Wolff — Parkinson — White syndrome (WPWS) is still the leading cause of supraventricular tachycardia in the world. The frequency of WPWS ranges from 0.1 to 0.3 % per 1000 people. It is worth noting that in patients with congenital heart defects, it increases to 0.5 %. The article highlights the main criteria of Wolff — Parkinson — White syndrome, its morphological justification, and the features of modern topical diagnosis. Also, the review of the main methods of treatment and rehabilitation of patients is presented.

Ventricular Noncompaction

Left ventricular noncompaction (LVNC) is a condition characterized by prominent ventricular trabeculae and deep intertrabecular recesses and has been described as a possible substrate for arrhythmias, thromboembolism, and heart failure. Herein, we explored the prevalence of LVNC morphology among hearts with congenital heart defects (CHD). We examined 259 postnatal hearts with one of the following CHD: isolated ventricular septal defect (VSD); isolated atrial septal defect (ASD); atrioventricular septal defect (AVSD); transposition of the great arteries (TGA); isomerism of the atrial appendages (ISOM); Ebstein’s malformation (EB); Tetralogy of Fallot (TF). Eleven hearts from children who died of non-cardiovascular causes were used as controls. The thickness of the compacted and non-compacted left ventricular myocardial wall was determined and the specimens classified as presenting or not LVNC morphology according to three criteria, as proposed by Chin, Jenni, and Petersen. Normal hearts did not present LVNC, but the CHD group presented different percentages of LVNC in at least one diagnostic criterium. The prevalence of LVNC was respectively, according to Chin’s, Jenni´s and Petersen´s methods: for VSD—54.2%, 35.4%, and 12.5%; ASD—8.3%, 8.3%, and 8.3%; AVSD—2.9%, 2.9%, and 0.0%; TGA—22.6%, 17%, and 5.7%; ISOM—7.1%, 7.1%, and 7.1%; EB—28.6%, 9.5%, and 0.0%; TF—5.9%. 2.9%, and 2.9%. VSD hearts showed a significantly greater risk of presenting LVNC when compared to controls (Chin and Jenni criteria). No other CHD presented similar risk. Current results show some agreement with previous studies, such as LVNC morphology being more prevalent in VSDs. Nonetheless, this is a morphological study and cannot be correlated with symptoms or severity of the CHD.

Standard Operation

To evaluate the invasiveness of a minimal access approach for simple congenital heart defects, and determine whether it can be regarded as a standard operation, 83 patients with an atrial septal defect and 73 with a ventricular septal defect underwent repair through a minimal skin incision and lower partial median sternotomy. There were no operative deaths, severe intraoperative complications, or conversion to full sternotomy. The clinical course of 106 patients was compared with that of 21 treated using a full sternotomy by the same surgeon; there were no significant differences, except in the operative time for ASD patients. The clinical courses of 2 minimal access subgroups (50 patients operated on by residents and 106 treated by the staff surgeon were compared; operative time, bypass time, ventricular fibrillation time (ASD repair), and cardiac arrest time (VSD repair) were significantly shorter in those operated on by the staff surgeon, but there was no difference in clinical course. The minimal access approach produced good cosmetic results, its invasiveness was similar to that of a full sternotomy, and it may be considered a standard operation for pediatric patients with septal defects.
