Estenose pulmonar é uma obstrução anatômica (estenose) do fluxo sanguíneo do ventrículo direito do coração para a artéria pulmonar. Pode ser dinâmica. El primer par, dos gemelas monocigóticas de 13 años de edad, en ambas se encontró severa estenosis infundibular y valvular pulmonar. En el segundo par.

Esto se conoce como un cortocircuito derecha-izquierda. We reviewed all the monozygotic twins with specific concordance in congenital heart lesions in the last 18 years. Tetralogy of Fallot in monozygotic twins.

Am J Med Genet ; Jpn J Thorac Cardiovasc Surg ; Case report and literature review. In the intensive care unit, the patient developed pneumonia due to Sthaphylocococus aureus, with bad and long evolution. Tetralogy of Fallot Tetralogy of Fallot is a congenital heart defect which usually involves four anatomical abnormalities of the pukmonar. Echocardiographic examination showed a severe infundibular and pulmonary valve infundibluar in both of them.

Echocardiogram demonstrated Tetralogy of Fallot with an obstructive 60 mmHg gradient in the right ventricular outflow tract. There are very few reports on specific concordance of congenital cardiac malformations.


It was not possible to disconnect the patient from ventilator. Opening in the ventricular septum between the left and right ventricles, the medical term for this condition is ventricular septal defect. Thickening of the right ventricular wall, the medical term for this condition is right ventricular hypertrophy.

Two pairs of twins with specific concordance in congenital heart lesions are presented. Accepted September 23, Estenoais differences between twins are not enough explained on genetic bases; it’s necessary to consider the role of other factors, probably acquired during the first stages of embryonic development.

Persistent truncus arteriosus in monozygotic twins: There are two other reports of specific concordance. Primary biases in twins studies.

Email questions or suggestions to robert pacificmedicaltraining. These are the two first pairs of twins with specific concordance in congenital cardiac lesions reported in Mexico. Tell us if there is a topic you want us to cover or a resource we can add to the site.

In This Issue Tetralogy of Fallot. Echocardiography and angiocardiography showed favorable anatomy Figure 2B. However, in previous literature usually it is esteosis specified whether concordance refers to either the presence of the same cardiac defect in both twins, or to some cardiac malformation present in the two. Narrowing of the pulmonary valve, the medical term for this pathology is pulmonary infundibular stenosis.

This is known as a right-to-left shunt. During surgery a laceration of the pulmonary artery with important bleeding occurred as a complication.

Cardiac catheterization confirmed the echocardiogram diagnosis and an additional stenosis was found at the origin of the left pulmonary artery Figure 2a. Abstract Two pairs of twins with specific concordance in congenital heart lesions are presented. It results in low oxygenation of blood due to the mixing of oxygenated and deoxygenated blood in the left ventricle via the ventricular septal defect, and preferential flow of the mixed blood through the overriding aorta because of the obstruction of the pulmonary stenosis.

The aetiology of congenital heart disease. Both patients were positive for microdeletion in chromosome 22q We will refer to specific concordance in the former concept.

Se encontraron dos pares de gemelos. Systolic gradient measured by Doppler was mmHg in U. Learning on the Go!
