[Aneurysm of the atrial septum associated with interatrial communication: a study of 12 cases by 2-dimensional color echocardiography]. / Aneurisma del septo auricular asociado a comunicación interauricular. Estudio de 12 casos con ecocardiografía bidimensional-color.

Between 1983-1991 we have studied 5,221 two-dimensional echocardiography in patients suffering cardiopathies. Twelve (0.22%) had an aneurysm of the atrial septum associated with atrial septal defect. Eight patients had other cardiac anomalies. The criteria used to diagnosis the aneurysm were: 1) The atrial septum central part protrudes in the atrium. 2) 6 mm aneurysm base. 3) Minimum distance from the base to the protrusion top 6 mm. The aneurysm was located in the oval fossa in 6 patients (50%) and in the other 6 patients the aneurysm was situated in the ostium secundum. The aneurysm base measured 7.79 +/- 1 mm and the left or right septum displacement was of 7.37 +/- 1.82 mm. The left displacement was observed in 10 patients (83.3%) and the right in 2 patients (16.6%). The spontaneous closure of atrial septal defect by the aneurysm was showed in 2 (16.6%) patients and in one (8%) was necessary the surgical closure. The other 9 patients: five rested along the follow-up without any change and other 4 patients died because of cardiac malformation. To conclude the atrial septal aneurysm associated with atrial septal defect in an unusual cardiopathy. Two dimensional echocardiography and Doppler color was diagnostic in all infants.

[Aortic atresia with situs inversus]. / Atresia aórtica con situs inversus.

We report a case of mitro-aortic atresia with situs inversus. The patient was studied with two-dimensional echocardiography and the diagnosis was confirmed in the necropsy. Our newborn infant is the second case reported with this abnormality and the first in our country.

[Angioplasty of a stenosed Blalock-Taussig shunt. Its long-term assessment]. / Angioplastia del Blalock-Taussig estenótico. Valoración a largo plazo.

A Blalock-Taussig shunt was performed in a child of 14 months diagnosed with tetralogy of Fallot associated with a complete atrioventricular defect. Seven months later, a balloon dilatation was performed because the shunt was stenosed in the site of the distal anastomosis. Repeat angiography we proved the patency of the shunt without restenosis 4 year later.
