Insulin and Glucose Metabolism in Pediatric Heart Failure

Thanks to progress in treatments and surgical techniques, about 30,000 children born with heart defects now reach adulthood every year in the United States. As a result, the number of adults who live with congenital heart disease has exceeded one million. And, of these, nearly 100,000 are living with severe heart defects. This has raisedContinue Reading

CHD Medications

Medicines are often needed to treat congenital heart defects until the defect can be repaired or corrected. Some complex acyanotic heart defects and most cyanotic heart defects require ongoing treatment with medicines even after the defect is repaired. Children with certain defects that cannot be completely corrected may have to take medicines for a longContinue Reading

Congestive Heart Failure

Congestive heart failure (CHF) is a condition in which the heart does not pump enough blood out to the rest of the body in order to meet the body’s demand for energy. The lungs may get flooded with extra blood and fluid if the left side of the heart is failing. On the other hand,Continue Reading

Heart Defect (PFO) May Play Role in Sleep Apnea

Study shows that a heart defect may make sleep apnea worse through contributing to oxygen deprivation. People with sleep apnea stop breathing temporarily many times during the night, because of an obstruction of the upper airways. This breathing cessation often leads to a fall in the oxygen concentration of the blood, known clinically as oxygenContinue Reading

Specific CHD’s and their surgeries

Patent Ductus Arteriosus (PDA) Before birth, there is a natural opening between the aorta (the main artery to the body) and the pulmonary artery (the main artery to the lungs) called the ductus arteriosus. This opening usually closes shortly after birth. PDA occurs when this opening fails to close; PDA occurs in about 10% ofContinue Reading

Basic Info on Blood Transfusion

What is a blood transfusion? When a child has low blood levels or is missing a part of the blood that the body needs, she is given blood through an IV. This is called a blood transfusion. Donated blood, which is stored in sterile plastic sacks, is given to the child through a needle orContinue Reading

Brief Overview of Aortic Translocation (Nikaidoh Procedure)

Dr. Hisashi Nikaidoh has received international recognition for the landmark procedure that bears his name following 20 years of successful surgeries. Children diagnosed with the rare triad of Transposition of the Great Arteries, Ventricular Septal Defect and Pulmonary Stenosis have a significantly improved prognosis after undergoing aortic translocation with reconstruction of the right ventricular outflowContinue Reading

BNP and NT-proBNP Testing for Heart Failure

I do not have first-hand experience with this test, however I recently read about a few pediatric CHD patients being given this test. I’m not sure how accurate or common this is for pediatric heart patients. What is being tested? These tests measure the concentration of BNP or NT-proBNP in the blood. The heart normallyContinue Reading

Common Molecular Mechanism Linked to 3 Seperate CHD’s

Three separate heart defects share a common defect at the molecular level, according to a study by members of the Center for Molecular and Human Genetics. Aortic Valve Stenosis (AVS), Coarctation of the Aorta (COA), and Hypoplastic Left Heart Syndrome (HLHS) are three cardiac defects that involve the heart’s left ventricular outflow tract (LVOT). AllContinue Reading

Cardiac Cycle

Cardiac cycle is the term referring to all or any of the events related to the flow or blood pressure that occurs from the beginning of one heartbeat to the beginning of the next. The frequency of the cardiac cycle is the heart rate. Each beat of the heart involves five major stages: The first,Continue Reading
