[Transcatheter aortic valve implantation for aortic stenosis. Initial experience].

Background: Aortic stenosis is a frequent disease in the elderly, and is associated with other systemic pathologies that may contraindicate the surgical procedure. Another option for these patients is percutaneous aortic valve implantation, which is less invasive. We present our initial experience with this procedure.

[Clinical guide practice. Patent ductus arteriosus].

Patent ductus arteriosus (PDA) is the most common congenital heart disease in Mexico. The clinical manifestations of the PCA are from asymptomatic patients to the presence of heart failure. Its management should be individualized based on clinical, hemodynamic data and presence of pulmonary hypertension.

[Percutaneous closure of inter-atrial communication with the Amplatzer device. Experience with 42 cases].

We report our experience on 42 patients treated with atrial septal defect (ASD) occlusion using Amplatzer device. Thirty patients were females and 12 were males, mean ages 26.5-years-old +/- 12 years (interval from 7 to 69 years).

[Tricuspid atresia associated with common trunk. A case report].

The tricuspid atresia associated with persistent truncus arteriosus is a rare anomaly. A case is presented of one male patient of three months age in which was detected a cardiac murmur. The diagnosis was made by echocardiography and confirmed by cardiac catheterization.

[Endomyocardial biopsy. Revision and experience of 176 procedures].

Endomyocardial biopsy (EB) is often used in the clinical evaluation of several cardiac disease. Hundred-seventy-six consecutive procedures were performed in 65 patients, 43 men and 22 women mean age was 29.86 +/- 11.

[Right ventricular thrombous and pulmonary artery aneurysms in Behçet's disease. Report of one case].

Unlabelled: Behçet's disease uncommon in the pediatric population. Intracardiac thrombus and bilateral pulmonary artery aneurysms are uncommon manifestations. We are reporting one case.

[Patent ductus arteriosus closure with a Nit-Occlud device. Experience with 13 cases].

We report our experience with the percutaneous closure of patent ductus arteriosus with a Nit-Occlud device made of Nitinol (Nickel-Titanium alloy) in 13 patients; 10 women and 3 men, average age of 23.2 +/- 21.1 years.

[Percutaneous closure of patent foramen ovale with amplatzer device. Report of two cases].

Objective: We present two cases of Patent Foramen Ovale (PFO) treated with percutaneous Amplatzer device.

Method: The first case corresponds to 48 years old woman with Ebstein's disease with moderate to severe hemodynamic repercussion and three cerebrovascular accidents, the last one under coumarin treatment, she received antiarrhythmic medication and despite of it developed 1st degree AV block, supraventricular and ventricular ectopia, rigth branch block. The second case corresponds to a 22 years old man with antecedents of cerebrovascular accident at the age of 21 with sequelae of convulsive crisis.

[Repair of interatrial septal defect with an Amplatzer device. Experience with 3 cases].

We performed transcatheter closure of an atrial septal defect (ASD) using an Amplatzer device in three patients, 2 women and 1 male child, aged 12, 54, and 4 years, respectively, coursing with ostium secundum ASD. Two with left to right shunt and the third with bidirectional shunt. The transesophageal echocardiogram revealed ASD with diameters of 13, 15, and 10 mm, the diameter with expanded catheter balloon was of 30, 26, and 17 mm, respectively.

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.
