Congenital Heart Disease Related To A Faulty Signal Transduction Pathway
Not likely.: Most congenital cardiac defects are due to multifactorial inheritance and environmental factors such as Folic Acid deficiency. I am not aware of specific studies linking them to a faulty signal transduction pathway, although such mechanisms frequently become the final common pathway of multiple etiological pathogenic factors. ...Read more
Heart disease is a condition in which a person has problems within his or her vascular system and heart, which includes both congenital birth defects and problems acquired later. Examples of heart disease include clogging (atherosclerosis) of the coronary (heart) arteries, heart attacks (obstructions of the arteries), damaged heart valves, heart muscle failure, and viral infections of the heart. Some major causes of heart disease include genetics, smoking, hypertension, high ...Read more
Is this correct? "Wolff Parkinson white synd. is an electrical abnormality in the heart where an accessory pathway exists leading to rapid heart rate"
Would a person with neonate repaired patent ductus arteriosus be at greater risk for heart damage or heart disease due to the congenital defect?
Hardly: Not to worry you , but even some very, very good surgeons have mistaken a wrong blood vessel for the PDA and ligated it instead. This includes the left pulmonary artery and even the descending aorta. Fortunately this is extremely rare. Other than that, there is basically no further risk of damage or disease. ...Read moreSee 4 more doctor answers
SVT Is the lifetime chance of devoloping venticular fibrillation due to accesory pathway capable of anterograde conduction <1% When ecg was normal?

In which theory does coarcatation aorta with arch hypoplasia fit in? The hemodynamic or the eptopic ductal tissue theory?
Not truly separate: I don't think that these causation theories are completely separate. Coarctation with arch hypoplasia tends to present with symptoms in the early neonatal period, and coarctation without arch hypoplasia may present later in life, but coarcation without arch hypoplasia is commonly seen in the neonatal period, too. Further discussion is beyond the space limitations here. ...Read more
If there's peripheral cyanosis due to peripheral vascular disease and central cyanosis due to heart disease simultaneously how to know each cause?
Combination : Various testing and history and exams. Blue babies are generally central. Some older persons have blocked vessels, bad lungs, and other signs and symptoms. A rare person will have both and several causes: congestive heart failure, smoker- COPD, atherosclerosis and DVT etc. One needs to evaluate multi system. ...Read more
PDA: Patent ductus.Get a more detailed answer ›
Confusing: Adults cardiologists often use the 3-letter acronym, chd, for coronary heart disease. Pediatric cardiologists use the same for congenital heart disease. Answer depends on who is using it usually. Always ask physicians to speak in words, not letters. They should. ...Read moreSee 1 more doctor answer
Is the valve regurgitation that is caused by atrioventicular septal defect (mr or tr) seen in doppler echo?
If nerve cells were attacked directly in a autoimmune disease could it cause loss of chemical neurotransmitters and electrical changes and processes ?
Which pain-causing diseases/disorders cause malfunction in transient receptor potential cation channels of subclass a type (trpa1)? Autoantibodies?
TRPA1 Gene Family: The best article i've read on this gene family is ===> http://www.Genecards.Org/cgi-bin/carddisp.Pl?Gene=trpa1. The clinical significance of mutations in this gene has been related to caffeine and nicotine sensitivity disorders, and rare environmentally-triggered pain disorders. The complete function of this gene family is not known. ...Read more
What is the name of an electrical shock delivered to the heart to correct certain abnormal heart rhythms called?
Multiple ways: Valve stenosis is the narrowing of a valve opening. Most commonly this causes flow disturbances which can be heard and is caused a murmur. Think of a kinked garden hose. The higher the velocity of the blood crossing the valve the louder the murmur. Other secondary sounds can occur but are more subtle. Pictured is a stenotic aortic valve. ...Read more
I don't understand: I don't understand your question. Do you mean when someone is born without certain organs at all? Or do you mean something like omphalocele or gastroschisis where the abdominal wall does not close up all the way (in utero) and the abdominal contents can be outside the abdomen (but still attached)? ...Read more
Migraine with aura-can causes b faulty willis circuitry in the brain, open p.F.O in the heart? Can cumulative vascular damage occur untreated attacks?
Yes: People with pfo tend to have problems with headaches. Generally it is thought that fixing the pfo helps. ...Read more
Not a rhythm problem: Bundle branch block is an anatomic or physiologic problem in conducting electrical impulses in part of the hearts conduction system. It is not a rhythm disturbance though it can be related to rhythm disturbances. Bundle branch blocks commonly exist with normal sinus rhythm. ...Read moreSee 1 more doctor answer
Born with it: It is a heart defect you are born with. It may be simple, moderate, or very serious. They include "holes in the heart", valve problems, malformed or absent chambers, valves, or blood vessels. Just under 1 % of all babies are born with some type of defect, often minor and temporary. They are usually diagnosed shortly after birth, occasionally much later. ...Read more
