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.

Tetralogy of Fallot is a congenital heart defect which usually involves four anatomical abnormalities of the heart. Jpn J Thorac Cardiovasc Surg ; Two pairs of twins with specific concordance in congenital heart lesions are presented.
Case report 2 Monozygotic twins with Tetralogy of Fallot J. Just like in the previous reports, both twins had the same disorder, with minor differences, particularly in the severity of the lesion.
Tetralogy of Fallot in monozygotic twins. Tetralogy of Fallot Tetralogy of Fallot is a congenital heart defect which usually involves four anatomical abnormalities of the heart.
Abstract Two pairs of twins with specific concordance in congenital heart lesions estenpsis presented. Total surgical correction was performed in January 28, During surgery a laceration of the pulmonary artery with important bleeding occurred as a complication. Echocardiographic examination showed a severe infundibular and pulmonary valve stenosis in both of them. Echocardiogram demonstrated Tetralogy of Fallot with an obstructive 60 mmHg gradient in the right ventricular outflow tract.
These are the two first pairs of twins with specific concordance in congenital cardiac lesions reported in Mexico.
Primary biases in twins studies. Persistent truncus arteriosus in monozygotic twins: Email questions or suggestions to robert pacificmedicaltraining.
In Junethe two patients underwent cardiac surgical correction with transannular patch under cardiopulmonary bypass.
Four abnormalities that make the blood circulate throughout the body without enough oxygen Narrowing of the pulmonary valve, the medical term for this pathology is pulmonary infundibular stenosis Thickening of the right ventricular wall, the medical term for this condition is right ventricular hypertrophy.
They were completely asymptomatic and their phenotypes were very similar Figure 1A. Imfundibular of the right ventricular wall, the medical term for this condition is right ventricular hypertrophy.
Manual of Neonatal Care Accepted September 23, In the first, the presence of persistent truncus infundibu,ar in both monozygotic twins, without DiGeorge phenotype syndrome and no deletion in chromosome 22q11 is described. Ventricular septal defect associated with pulmonary hypertension in monozygotic twins a case report with surgical repair.
The McGoon index was 1. Introduction Since Price’s report in1 it has been recognized that monozygotic twins provide an opportunity to study genetic contribution in the development of cardiovascular malformations. Systolic gradient measured estenodis Doppler was mmHg in U. It is the most common cause of blue baby syndrome. However, in previous literature usually it is not 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.

It was not possible to disconnect the patient from ventilator. This is known as a right-to-left shunt. Feel free to read them now and save them for later use such as with a patient or as a study guide for coursework.
Echocardiography and angiocardiography showed favorable anatomy Figure 2B.
We reviewed all the monozygotic twins with specific concordance in congenital heart lesions in the last 18 years. In February surgical correction was performed with transannular patch, pulmonary valve prosthesis, and patches in left main coronary setenosis pulmonary arteries; the ventricular septal defect was closed too.
