Coumel tachycardia in children.

Background: Coumel tachycardia is an infrequent form of supraventricular tachycardia (SVT) that usually occurs in infants and children. It is a tachycardia mediated by an accessory pathway with retrograde slow conduction that explains the classic ECG pattern with long RP' interval and negative P waves in leads II, III, and aVF. In this study, we describe the clinical course and management of Coumel tachycardia in children.

Idiopathic left fascicular ventricular tachycardia in children and adolescents.

Background: Idiopathic ventricular tachycardia (VT) in children with structurally normal hearts is generally unrelated to the risk of sudden arrhythmic death. Still, it may be associated with deterioration in the quality of life. VT involving the fascicular conduction system is the most typical form of idiopathic left VT.

Incremental role of three-dimensional over two-dimensional ultrasound in the assessment of traumatic peripheral arteriovenous fistula.

We present a patient with an accidental self-inflicted stab wound to his right thigh in whom three-dimensional (3D) ultrasound was able to find two communications between the right femoral artery and the femoral vein, in contrast to two-dimensional (2D) peripheral ultrasound which could find only one communication between them, thereby showing an incremental value of 3D over 2D ultrasound.

Anomalous origin of the left coronary artery from the pulmonary artery. Echocardiographic diagnosis.

Unlabelled: The experience with echocardiographic diagnosis of five cases of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA) is reviewed.

Material And Methods: all cases with a diagnosis of ALCAPA during a 10 year period were included.

Results: two age groups were clearly identified: infants and older patients.

[Congenital coronary fistula. Clinical presentation in 7 cases and literature review].

Unlabelled: Congenital coronary artery fistulas are uncommon anomalies, however themselves may resemble the whole spectrum of cardiac manifestations. Clinical presentations vary considerably from adults to children.

Material And Methods: patients with coronary artery fistula diagnosed by selective coronariography in the period from 2000 to 2007 were included.

[Cardiac rhabdomyoma surgically treated with success. Review of literature].

The primary cardiac tumors are inusual, the incidence varies in all the ages between 0.005 to 0.05%.

[Stenting and redilatation of the ductus arteriosus in univentricular heart with pulmonary atresia. A case report].

Complex congenital heart disease with pulmonary atresia is ductus arteriosus-dependent. Two palliative treatments have been available for years: a systemic pulmonary shunt and prostaglandin E1 infusion. Recently, interventional cardiology has offered a new procedure for these patients: stenting of the patent arterial duct.

Balloon angioplasty in aortic coarctation: a multicentric study in Mexico.

Objectives: To analyze immediate and long-term results of balloon dilation for aortic coarctation in a three-center experience in Mexico, and to determine factors associated with increased risk.

Background: Results demonstrated that the procedure is effective and safe, however its use in some groups is still controversial, specially in neonates and infants.

Methods: In a ten-year period, 333 patients with aortic coarctation on underwent balloon dilation with an immediate success rate of 93.
