[Early results of surgical treatment of patients with Wolff-Parkinson-White syndrome].

Successful dissection of accessory pathways (AcP's) was performed in 19 of 20 patients. 15 pts had single, 4 double and 1 patient had 3 accessory pathways (AcP's). The patient with 3 AcP's was operated twice. During the first operation two AcP's were eliminated. The third one was revealed during the postoperative electrophysiologic study. Verapamil facilitated its manifestation and localisation. No patient had syncope or atrio-ventricular tachycardia after the operation. In 3 of 10 patients who had atrial fibrillation before the operation, episodes of AF occurred in the early postoperative period. Conduction to the ventricles was through the normal conduction system. Dissection of AcP's prevented extremely fast ventricular response and syncope. After discontinuation of amiodarone more frequent ventricular premature beats occurred in patients with long history of cardiac arrhythmias, on drugs for a long time and in patients who had heart dilatation. Several months after the operation VEB were less frequent, probably because tachycardias did not occur, left ventricle geometry improved, and cardiodepressant drugs were discontinued. Previously these patients had been treated usually with combination of 2-3 such drugs. After the successful dissection of AcP's the patients lost the feeling of illness and do not feel being imperilled. Children can attend schools normally and some adult patients resumed their professional activities.

Echocardiographic evaluation of aortic cusp prolapse in children with ventricular septal defect.

Echocardiograms were obtained from 48 Japanese children with ventricular septal defect (16 having aortic cusp prolapse, Group I, and 32 without it, Group II). In the case of right coronary cusp prolapse, the right coronary sinus protrudes anteriorly into the right ventricular outflow tract, and thus, the anteroposterior diameter of the aortic root increases. In the case of non-coronary cusp prolapse, the non-coronary sinus bulges posteriorly into the right ventricle, and thus, the aortic root increases in size. For evaluating the degree of these prolapses quantitatively, we measured the aortic root diameter echocardiographically and expressed them as a percent of a normal one. In Group I the aortic root diameter was 131 +/- 9% (mean +/- SD) and in Group II it was 105 +/- 7%, and the difference between the 2 groups was statistically significant (p less than 0.001). In Group I 14 of the 16 patients had a value greater than 120%, while all 32 patients of Group II had a value smaller than 120%. Thus, in children with ventricular septal defect, an aortic root diameter greater than 120% of normal suggests the presence of aortic cusp prolapse. Systolic semiclosure of the aortic valve was found in 8 patients of Group I (50.0%) and in 2 of Group II (8.7%). Coarse systolic fluttering of the pulmonary valve with an amplitude of greater than 3 mm was detected in 6 of Group I (40.0%) and in 3 of Group II (10.0%). Therefore, semiclosure of the aortic valve and fluttering of the pulmonary valve are considered to be also useful for evaluating aortic cusp prolapse qualitatively.

Noncardiac surgery: postoperative arrhythmias.

Postoperative arrhythmias are common and represent a major source of morbidity after both cardiac and noncardiac surgical procedures. Postoperative dysrhythmias are most likely to occur in patients with structural heart disease. The initiating factor for an arrhythmia in a given patient after surgery is usually a transient insult, such as hypoxemia, cardiac ischemia, catecholamine excess, or electrolyte abnormality. Management includes correction of these imbalances and medical therapy directed at the arrhythmia itself. The physiologic impact of arrhythmias depends on arrhythmia duration, ventricular response rate, and underlying cardiac function. Similarly, urgency and type of treatment is determined by the physiologic impact of the arrhythmia, as well as by underlying clinical status. The purpose of this review is to provide current concepts of diagnosis and acute management of arrhythmias after noncardiac surgery. A systematic approach to arrhythmia diagnosis and evaluation of predisposing factors is presented, followed by consideration of specific bradyarrhythmias and tachyarrhythmias in the postoperative setting.

[Atrial fibrillation and flutter in children].

Flutter and atrial fibrillation are extremely rare in children. Their aetiology and pathogenesis vary from one case to another. The clinical picture may be influenced by a number of factors (age, duration of the arrhythmia, ventricular frequency), while the natural history is often related to the presence or otherwise of associated cardiopathies. There is no standard treatment. Digitalis with or without other antiarrhythmic drugs is often employed as the drug of choice, though its place may be taken by ayodarone or verapamil.

[Evaluation and prognosis of fetal arrhythmia].

From January 1986 to August 1990, a fetal arrhythmia was diagnosed in 97 pregnant women referred to our unit. Atrial or ventricular extrasystoles were the most frequent rhythm disturbance encountered (71%). They were always well tolerated and all disappeared during the perinatal period. Tachycardia was found in 16 fetuses; 6 had a supraventricular reentrant tachycardia, 6 an atrial chaotic tachycardia, 1 an ectopic atrial tachycardia and the remaining 3 an atrial flutter. A congenital heart malformation was present in 4 fetuses. The arrhythmia induced hydrops fetalis in 25% of cases. One hydropic fetus died in utero and another needed premature delivery. Bradycardia was diagnosed in 12 cases, 3 had benign atrial blocked extrasystoles, 3 others sinus bradycardia due to fetal distress and 6 atrio-ventricular block. Atrio-ventricular block was associated with congenital malformation in 4 cases (66%). All these fetuses were hydropic and died. The 2 fetuses without cardiac malformation tolerated well their bradycardia during fetal life. Fetal arrhythmia is not rare, but in most cases is benign. Sustained tachycardia requires prompt treatment, because when hydrops fetalis appears the prognosis is worse. The major prognostic factor for atrio-ventricular block is the association with a cardiac malformation.

Pediatric dysrhythmias.

Arrhythmias in children are less common than in adults but are increasing because of successful repair of congenital heart diseases. Supraventricular tachycardia is the most common symptomatic pediatric tachyarrhythmia. Atrial flutter and atrial fibrillation in children are attributed largely to structural heart disease. Bradycardia is defined as a heart rate less than the lower limit of normal for a child's age, and the most common cause is sinus bradycardia. Despite the infrequent occurrence of arrhythmias, it is crucial to expeditiously identify and treat certain rhythm abnormalities because they can lead to further decompensation.

Permanent transfemoral pacemaker implantation in a child with Maroteaux Lamy syndrome.

Permanent transfemoral pacing has been described as an alternative route in patients in whom the superior venous approach is not feasible. This report describes the use of the femoral venous approach to insert a permanent pacemaker in a child with Maroteaux Lamy syndrome who has complete atrioventricular block and abnormal subclavian venous anatomy. Transfemoral pacing may be a suitable alternative in children with short stature.

Short- and intermediate-term efficacy of amiodarone in infants and children with cardiac arrhythmia.

The antiarrhythmic effect of amiodarone was examined in this retrospective study in a group of 20 patients with a mean age of 8.5 +/- 6.7 years (range 42 days to 20 years, median 9 years). Five patients with atrial flutter, one patient with atrial fibrillation, two patients with an intermediate rhythm between atrial flutter and atrial fibrillation, four patients with chaotic atrial tachycardia, three patients with atrioventricular reentry tachycardia, two patients with junctional ectopic tachycardia, and three patients with ventricular arrhythmias were treated with amiodarone. The mean duration of therapy was 9.1 +/- 12.3 months (range 1 month to 4 years). Before amiodarone treatment, 18 patients had been unresponsive to various antiarrhythmic drugs (range 1-8, median 2). Two patients received amiodarone as an initial therapy. It was administered orally at a dose of 10 mg/kg once per day for 10 days and then decreased to 5 mg/kg once per day. Amiodarone was effective in 16 patients (80%). Side effects occurred in three patients, including thyroid dysfunction, elevation of liver enzymes, and keratopathy. All side effects disappeared upon cessation of the therapy. We recommend amiodarone for the treatment of childhood arrhythmias, especially for the refractory types.

Advances in the acute pharmacologic management of cardiac arrhythmias.

Safe and effective control of rapid ventricular rates in acute-onset atrial fibrillation (AF) can be accomplished with intravenous calcium antagonists, beta-blockers or amiodarone; digoxin is less effective. If pharmacologic cardioversion of AF is desired, single oral doses of propafenone or flecainide are safe and effective in patients without structural heart disease. Intravenous ibulitide is moderately effective in the conversion of persistent AF or atrial flutter, with a small risk of proarrhythmia. In wide QRS complex tachycardia of uncertain origin, adenosine and lidocaine are no longer recommended. Procainamide or amiodarone are the treatment options, but attempts should be made to define the origin of tachycardia. In the treatment of monomorphic ventricular tachycardia, lidocaine is no longer recommended; procainamide or amiodarone are the recommended therapies. In polymorphic ventricular tachycardia with a normal QT interval, beta-blockers are recommended. In shock-refractory ventricular fibrillation, lidocaine, and magnesium are ineffective; intravenous amiodarone should be the treatment of choice.
