Conditions we treat

Heart disease is a medical term used to refer to any condition or disease of the heart. There are two types:

Congenital heart diseases are those that originate when the baby is in the womb, while acquired heart diseases are those that are acquired after birth.

At the Pediatric Heart Center, we treat all types of heart disease in pediatric patients, and in those adults who require it. Some of the most frequent are the following:

Patent Ductus Arteriosus (PDA)

Before birth there is a vessel, called the ductus arteriosus, which connects the aorta with the pulmonary artery. This structure closes almost immediately at birth. When it doesn’t close, there is blood going to the lungs that mixes from the aorta into the pulmonary artery. It usually occurs in premature patients, but it can exist in any child.

Atrial Septal Defect (ASD)

There is an abnormal hole in the septum that separates the upper chambers of the heart, causing the lungs to receive more blood than usual and become congested.

Ventricular Septal Defect (VSD)

There is an abnormal hole in the septum that separates the lower chambers of the heart, which communicates the high-pressure left chamber (or left ventricle) with the low-pressure right chamber (or right ventricle) and causes the lungs to receive more blood than usual.

Tetralogy of Fallot:

This heart disease is a combination of four heart defects:

Subpulmonary stenosis. Right ventricular outflow pathway is narrow. The obstruction is usually below the pulmonary valve, but the pulmonary valve, and the pulmonary artery itself, are generally also affected and narrow. This causes blood to pass from the right ventricle to the left ventricle through the orifice, or ventricular septal defect, that connects the two ventricles.

Overriding aorta. As a consequence of the narrowing of the pulmonary artery, the aorta is “overriding” above the wall that separates the two ventricles and the ventricular septal defect. The non-oxygenated blood that is found on the right side of the heart, and due to the difficulty it finds to pass to the pulmonary artery, then reaches the aorta directly and causes cyanosis.

Right ventricular hypertrophy. As a consequence of the difficulty of the ventricle to expel blood into the lungs, there is an increase in the thickness and size of the heart muscle of the right ventricle.

Ventricular Septal Defect. A hole in the wall of the ventricles that causes non-oxygenated blood on the right side to mix with oxygenated blood on the left side.

Atrioventricular Canal (AV)

It is a complex malformation that involves various structures of the heart, including the septum that separates the upper chambers, the septum that separates the lower chambers, and the valves that separate the upper chambers from the lower chambers. These alterations in the heart structure cause blood short circuits from the left side to the right side, congestion of the lungs and malfunction of the heart valves involved.

Tricuspid Atresia

In this disease there is no tricuspid valve, which is what allows the passage of blood without oxygen from the right atrium to the right ventricle, to be expelled from there to the lungs to be oxygenated and return to the left side of the heart.

Transposition of the Great Arteries

In a normal heart, the aorta connects to the left ventricle, while the pulmonary artery connects to the right ventricle. In the case of a transposition of the great arteries, the aorta is poorly connected with the right ventricle and the pulmonary artery with the left ventricle, causing the non-oxygenated blood to go directly to the body, while the oxygenated blood goes to the lungs.

Atrioventricular Canal (AV)

It is a complex malformation that involves various structures of the heart, including the septum that separates the upper chambers, the septum that separates the lower chambers, and the valves that separate the upper chambers from the lower chambers.

Truncus arteriosus

The heart normally has two separate arteries that allow blood to be carried to the lungs and the body; in the case of the truncus arteriosus, the aorta and the pulmonary artery arise as just one vessel that eventually divides into two separate arteries.

Pulmonary stenosis

The pulmonary valve has a narrowing that makes it more difficult for blood to flow to the lungs. The extreme degree of pulmonary stenosis is pulmonary atresia.

Pulmonary atresia

In this heart disease, the pulmonary valve does not develop, and blood cannot pass from the right ventricle to the pulmonary artery. As a consequence, the right ventricle is affected in its development and its size may be smaller than usual.

Aortic stenosis

The aortic valve, located between the left ventricle and the aorta, does not form properly, and has a narrowing that makes it difficult to pump blood to the body, forcing the heart to work harder.

Coarctation of the Aorta

The aorta, the main artery that carries oxygenated blood to the body, follows an upward path when leaving the heart, to later rotate, form an arch, distribute blood to the arms and head, and finally descend to carry blood throughout the body.
Coarctation of the aorta is a narrowing located at the junction between the part of the aortic arch and the descending part, often in the shape of an “hourglass”, which obstructs the flow of blood to the lower part of the body. This forces the left ventricle to work harder to transport blood through the narrowing. In newborns, coarctation of the aorta is frequently associated with a narrowing of the entire arch of the aorta, and surgical correction must therefore include not only the area of coarctation, but also the narrow area of the arch .

Hypoplastic Left Heart Syndrome

It is a combination of severe abnormalities of the left portion of the heart and the large vessels. The deficient development of the aortic valve, which communicates the left ventricle with the aorta, causes an inadequate development of these two structures as well. At birth, children affected with this malformation are completely dependent on the right ventricle and that the ductus arteriosus, which normally closes spontaneously, remains open (usually thanks to the administration of a drug called prostaglandin), to maintain blood circulation to the entire body during the surgery called the Norwood procedure.
Surgical treatment is very complex. It consists of forming, from the pulmonary artery, whose development is normal, and from the poorly developed aorta, an outlet for blood to the whole body.

In addition, we treat a wide range of conditions,
the most common of which are:

  • Heart rhythm disturbances: Changes in heart rate or rhythm, where the heart may beat faster, slower, or irregularly. An arrhythmia may be harmless and be considered normal or a sign of a heart problem
  • Chest pain. It is one of the most common causes of consultation with the pediatric cardiologist, generally this pain can be benign, however, it is important to rule out a possible cardiological cause, especially when the pain is associated with exercise.
  • Heart murmur: It is a sound generated by the turbulent passage of blood within the heart or the large vessels, which can be normal (innocent, functional or benign), that represent the majority of cases, or secondary to heart disease.
  • Faints: It is the loss of alertness that occurs suddenly, completely, and temporarily, which resolves spontaneously usually without medical intervention. However, it can also be secondary to a heart problem.
  • Systemic arterial hypertension: It is the elevation of blood pressure above the expected figures of age, it can be secondary to heart or metabolic diseases or be hereditary. It is important to identify and treat it early to prevent long-term complications.

And other more complex ones, which include:

  • Anomalous left coronary artery of the pulmonary artery
  • Anomalous Pulmonary Venous Return (TAPVR or PAPVR)
  • Aortopulmonary window
