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.

In agreement with other authors, these differences could be explained by the influence of other factors probably acquired during the first stages of embryonic development.

Cardiac catheterization confirmed the echocardiogram diagnosis and an additional stenosis was found at the origin of the left pulmonary artery Figure 2a. Case report 1 Monozygotic twins with pulmonary stenosis U.

Case report 2 Monozygotic twins with Infkndibular of Fallot J. Have an idea for a new CME course related to healthcare Spanish?

In February surgical correction was performed with transannular patch, pulmonary valve prosthesis, and patches in left main coronary and pulmonary arteries; the ventricular septal defect was closed too. They were completely asymptomatic and their phenotypes were very similar Figure 1A. This is known as a right-to-left shunt.

In both twins, Tetralogy of Fallot was diagnosed by echocardiogram, cardiac catheterization and angiocardiogram. However, in previous literature usually it infundibualr not specified whether concordance refers to either the presence of the esteenosis cardiac defect in both twins, or to some cardiac malformation present in the two.

We reviewed all the monozygotic twins with specific concordance in congenital heart lesions in the last 18 years. In one of the reports, both estenoxis had pulmonary atresia and the same intracardiac defects, with anatomic differences in large vessels.

Monozygotic twins with Tetralogy of Fallot. 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 infunxibular the overriding aorta because of the obstruction of the pulmonary stenosis.

Am J Human Genet ,2: Curchill Livingstonep The goal of this newsletter is to provide you with enough information to be useful, but not more than can be learned within the busy schedule of a health care worker. Narrowing of the pulmonary valve, the medical term for this pathology is pulmonary infundibular stenosis. Esto se conoce como un cortocircuito derecha-izquierda. The McGoon index was 2. Thickening of the right ventricular wall, the medical infundihular for this condition is right ventricular hypertrophy.

In the second twin no previous shunt was done.

We will refer to specific concordance in the former concept. There are two other reports of specific concordance. Monozygotic twins with pulmonary stenosis. Fifteen days later, this twin died because of septic shock. In fluorescence hybridization test in situ all patients were negative for microdeletion in chromosome 22q In the first, the presence of persistent truncus arteriosus in both monozygotic twins, without DiGeorge phenotype syndrome and no deletion in chromosome 22q11 is described. Anatomic 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.

Case report and literature review. Indian Heart J ; In Junethe two patients underwent cardiac surgical correction with transannular patch under cardiopulmonary bypass.

Primary biases in twins studies. Echocardiogram demonstrated Tetralogy of Fallot with an obstructive 60 mmHg gradient in the right ventricular outflow tract. In the intensive care unit, the patient developed pneumonia due to Sthaphylocococus aureus, with bad and long evolution.

During surgery, severe pulmonary valve stenosis with hypoplastic annulus was found in both of them. Opening in the ventricular septum between the left and right ventricles, the medical term for this condition is ventricular septal defect. pulmomar

In This Issue Tetralogy of Fallot. This condition is characterized by noticeable cyanosis, fatigue, a heart murmur, delayed growth and physical development, dyspnea on exertion, and finger clubbing. These are the two first pairs of twins with specific concordance in congenital cardiac lesions reported in Mexico.

Aneurisma del seno de Valsalva y estenosis pulmonar infundibular

Today, six years after the procedure, both patients are asymptomatic with normal development and a control echocardiogram revealed a residual gradient below 20 mmHg and minimal pulmonary insufficiency. Tetralogy of Fallot in monozygotic twins.

Monozigotic twins with chromosome 22q11 microdeletion and discordant phenotypes in cardiovascular pattering. Am J Med Genet ; Learning on the Go! Echocardiographic examination showed a severe infundibular and pulmonary valve stenosis in both of them. The patients recovered uneventfully from operation. 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.

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. Congenital heart disease in twins; Congenital lesions in twins; Specific concordance in twins; Monozygotic twins; Valvar pulmonary stenosis; Tetralogy infundlbular Fallot. Jpn J Thorac Cardiovasc Surg ; Abstract Estenosid pairs of twins with specific concordance in congenital heart lesions are presented.
