Congenital Heart Diseases ( Chd )

Approximately, 1 of every 500 people is affected with hypertrophic cardiomyopathy, it is important for patients to understand the dynamics of the disease as it could potentially be life threatening. In most cases, the patients quality of life is not affected, but a few will experience symptoms that cause significant discomfort or undetected complications that could lead to sudden cardiac death. With that in mind, it would be beneficial to recognize what it is, specific causes, the steps of diagnoses, and the options for treatment.

As this disease progresses and the workload of the heart is consistently increased, ventricular hypertrophy occurs. At first, the hypertrophied heart muscles will increase contractility, thus increasing cardiac output; however, as hypertrophy of the ventricular myocardial cells continues, it begins to have poor contractility, requires more oxygen to perform, and has poor circulation from the coronary arteries. This can result in heart tissue ischemia and lead into cardiac dysrhythmias (Lewis et al. 2014, 768).

Young children who have hypertrophic cardiomyopathy tend to have no symptoms of their condition until

Congenital heart disease is a cardiovascular condition resulting from an abnormality in the structure of the heart. The exact time this defect forms is unknown but it is during the fetal development in the womb. Researchers think the defect could be case partially by genetics and medical conditions of the fetus and the parents. If the baby’s mother had rubella, while pregnant or other conditions such as diabetes could have caused the defect. Some medications that were taken by a pregnant mother could also have caused birth defects. An error on chromosome 22 could also have caused the heart defect. Some symptoms that a person may have a congenital heart may not show up until later in life but many children also have the symptoms. Symptoms of a congenital heart defect are abnormal heartbeat, bluish tint to skin, shortness of breath, dizziness or fainting, and swelling of body tissues and organs.

Hypoplastic Left Heart Syndrome is a very serious birth defect. Studies say, “each year approximately… 640 to 1440 infants in the United States are born with HLHS” (Paediatr Child Health,2). Hypoplastic Left Heart Syndrome, also known as HLHS, is a birth defect where the left ventricle of the heart is either underdeveloped or absent. Today, there are heart surgeries that can help children born with HLHS survive longer and sometimes even live long, happy lives. Though, not all children survive HLHS. Many infants die whilst waiting for a donor heart.

If the heart and its chambers aren't formed correctly prior to birth, the healthy parts have to work all the harder.

According to the WHO, cardiovascular diseases have been the leading cause of death globally claiming 17 million lives a year, more deaths than all cancer combined (Chiu and Radisic, 2013). Cardiovascular disease is responsible for a preponderance of health problems and its impact is expected to grow further as the population ages. In the UK, NHS spends about £7.74 billion as the expenditure to deal with cardiovascular diseases (Barton et al., 2011). Cardiovascular disease in the form of myocardial infarction has become the principle cause of death in developed countries, accounting for nearly 40% of all deaths (http://www.bhf.org.uk/). Congenital heart defects, which occur in nearly 14 of every 1000 new-born children, is another tragic fact that baffles medical industry (http://www.heart.org/). About 61 million Americans (almost one-fourth of the population) live with cardiovascular diseases, such as coronary heart disease, congenital cardiovascular defects, and congestive heart failure.

Congestive heart hailure, also known as CHF or heart failure, affects the lives of 5 million Americans each year with 550,000 new cases diagnosed yearly. (Emory healthcare, 2013) CHF is a medical condition in which the heart has become weak and cannot pump enough blood to meet the need for oxygen rich blood required by the vital organs of the body, less blood is pumped out of the heart to the organs and tissues in the body and pressure in the heart increases, it does not mean the heart has stopped working. (Murphy, 2013) Once the heart has become weakened by conditions such as hypertension, abnormal heart

Critical Congenital Heart Defect (CCHD) is a subgroup of congenital heart defects that normally necessitates surgical intervention or catheterization procedure during the neonatal period (Good, Canale, Goodman, & Yeager, 2015). According to Mahle et al. (2009), although there are measures taken to detect CCHD like prenatal ultrasound and comprehensive newborn physical examination during newborn’s birth hospitalization, there is still a significant percentage of newborns with CCHD that is left undetected and discharged home without being diagnosed. Delay in diagnosis of CCHD increases morbidity and mortality (Mahle et al., 2009). In response to this, Riede et al. (2010) mentioned that the diagnostic gap in CCHD could be bridged by screening newborns using pulse oximetry

Critical Congenital Heart Defects are abnormalities of the heart structure that are present at birth. These occur because of incomplete or abnormal development of the fetus’ heart. These defects can cause severe mortality within the newborn stage (Goldstein, 2013, p.1). Several are known to be linked to genetic disorders such as Down syndrome and others are thought to be linked to environmental factors that women can be exposed to while pregnant. The cause of most CCHD’s is unknown.

As cardiomyopathy progresses, the heart becomes weaker and is less able to pump blood normally. This results in heart failure. There are different types of cardiomyopathy- hypertrophic, dilated, and restrictive. Hypertrophic cardiomyopathy occurs when the heart muscle cells enlarge which causes the thickening of the left ventricular wall. Although the ventricle size stays normal, the thickening makes it harder for the heart to pump blood. In some cases, the septum also thickens and expands to the left ventricle which causes a blockage of blood flow out of the left ventricle. The cause of the disease is unknown but hypertrophic cardiomyopathy is usually caused by changes in the genes in heart muscle proteins. It can also develop due to

Risk for having CAD or established CAD, previous MI or heart failure with decreased ejection fraction and ventricular arrhythmias are the known risk factors for SCD[17, 136]. The estimated incidence rate of SCD in infants, children, adolescents, and young adults is about 1.3 to 8.5 per 100,000 patient/years [137] but it still costs to thousands life per year. Sudden infant death syndrome accounting for approximately 10% of the crib death is believed to be due to cardiac arrhythmia or long QT syndrome [138]. A study suggest that out of 158 deaths of American athletes, 30% were due to hypertrophic cardiomyopathy and 13% due to abnormal blood circulation, 10% due to increased cardiac mass due to cardiomyopathy [139]. Another study suggest 20% death due to CAD and 10% deaths due to right ventricular cardiomyopathy/ dysplasia in young population [140]. Patients suffering from SCD with normal heart or without any cardiac disease history, on autopsy show structural abnormalities. Sudden unexplained deaths are also a major concern in epidemiology of SCD and careful post-mortem and histological examination can play a vital role [17]. In a study with 270 autopsies 55 were found to have structural heart disease and a specific cause for death were found in 180 cases with 65% having CAD, 14% with congenital anomalies and 11% with myocarditis.

According to the US Census Bureau, population estimates in 2004, in the United States it is estimated that approximately .02% of the population is effected by hypertrophic cardiomyopathy. Which is two in

Children with congenital heart disease (CHD) are at increased risk for psychosocial issues, decreased quality of life and decreased resilience. The standard of care for children with CHD cared for in the Heart Transplant and Heart Failure clinic did not include routine screening for psychosocial issues with a standardized tool. The purpose of this Doctor of Nursing Practice (DNP) project was the implementation of a protocol that screened children followed in this clinic for psychosocial issues, quality of life and resilience, with appropriate psychosocial referral as indicated by positive screening results.

Congenital heart diseases (CHDs) are the most prevalent of all birth defects and the leading cause of death in the first year of life, (1) with an annual prevalence ranging from six to twelve affected infants per 1,000 live births. (2)
