Left Heart Syndrome

Left-sided heart failure is the most common type of heart failure, and it is a result of left-ventricular dysfunction. This disease poses a significant threat to patients because the primary function of the left side of the heart is to provide sufficient oxygenated blood to satisfy the metabolic demands of the body’s cells. Understanding the main function of this portion of the heart will help with the understanding of other complications associated with this diseased. Left-sided heart failure is usually the result of the loss of heart muscle function, specifically in the left ventricle secondary to coronary artery disease, prolonged hypertension, or myocardial infection (Lewis et al. 2014, 766). The

2. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? Explain your answer based on blood pressure and resistance in the heart and great vessels. It goes left to right during systole. The difference is normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, and then is pumped into the lungs where it receives oxygen. Oxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle, and then is pumped out to the body through the aorta. But when an infant has ventricular septal defect it still allows oxygen-rich (red) blood to pass from the left ventricle, through the opening in the septum, and then mix with oxygen-poor (blue) blood in the right ventricle. (ROCHESTER.EDU) but instead when systole occurs the blood gets mixed because of the septum therefore heart needs to pump harder to ensure that enough blood with oxygen reaches the body.

At this point, we do not know exactly what are the settings, we have previous requested pacemaker operative report from Regions. Unfortunately, from what he is telling today, his date of the birth was not correct as such dose report were not same. He noted that he thinks he came back from the hospital, he has not had similar complaint or concern or report of chest pain. It should be noted that hospital records, with a troponin that was negative, 12-lead EKG was similar to the one that was obtained here, essentially identifying sinus bradycardia with first-degree AV block, left ventricular hypertrophy with repolarization abnormality. QT was prolonged, similar EKG obtained at facility also identified pretty much the same abnormality pattern. Troponin was negative. Other workup included chest x-ray in the hospital were all unremarkable. Today he is not reporting any chest pain, no shortness of breath, no nausea or emesis. He has got healed ____ scar to the left chest from pacemaker implantation which is completely healed but slightly

Individuals with this disorder further acquire congenital heart defects. It specifically blocks off the natural blood flow from the lungs and right chamber of the heart and/or causes an anomalous gap in the barrier that divides the heart chambers in two. Another symptom of this disorder are the problems involved in the digestive system. People who have this syndrome are

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.

One of the rarest of congenital cardiac defects is Hypoplastic Left Heart Syndrome, HLHS. This syndrome is described as a collection of anomalies affecting the left heart and connecting structures. Due to advancements in surgical intervention mortality rates in neonates with Hypoplastic Left Heart Syndrome have decreased. Management of these patients requires a symphony of multidisciplinary teams including fetal and pediatric cardiologist, cardiac surgeons, neonatologist, pulmonologist, nutritionist and family counselors. Options currently comprise of heart transplant, three-staged palliative surgery and comfort care. There may be co-morbidities present which further complicate treatment, but with surgical intervention the

Your childhood is something that is totally unforgettable. Whether it was good or bad, everyone can remember memories of it. Maybe knowing that you can help a child's childhood might make you want to listen to these heartwarming stories from the Make-A-Wish website.

The only hope of surviving this is a connection between the sides of the heart. Usually this connection closes a few days after birth, but in this case it doesn't. So the right side pumps all the blood out, but when it tries to come back through the left side the whole is closed. This can quickly cause death because of no blood circulation. Babies born with hypoplastic left heart syndrome are usually put on medicine right after birth so the hole doesn't close and the blood can keep

They did an ultrasound while I was still inside my mother when she was seven months pregnant. The doctors were able to tell that my heart had developed a single pumping chamber and my aorta was smaller than my lung arteries. They knew that I would need an operation called the Norwood procedure. Since the aorta was small as was the left ventricle, the right ventricle had to do all the work of pumping the blood to the lungs and through the ductus arteriosus to the rest of the body.

Congenital left ventricular outpouching (LVO) is a rare disorder in which a confined protrusion arises from the left ventricular (LV) free wall. The terms LV aneurysm, LV diverticulum, double-chambered LV and LV accessory chamber have been used interchangeably in the literature [1–9], however anatomical differences do exist between these terms [10]. LV aneurysm is an expansible thin-walled, usually fibrotic myocardium and pericardium, pouch contracting in asynchrony with the LV and has a wide communication with the LV cavity. Conversely, an LV diverticulum has three cardiac wall layers (endocardium, myocardium and pericardium), contracts in synchrony with the LV and has a narrow connection to LV. LV accessory chamber presents an entity that combines some criteria of both aneurysm and diverticulum. Its wall is similar to a diverticulum but it has a wide communication with the LV as an aneurysm. Lastly, double-chambered left ventricle displays a combination of the above-mentioned characteristics.

Cardiomyocytes or cardiac muscle cells are vital for the heart function despite their numbers being considerably lower than other types of cells in cardiac tissue. The loss of cardiomyocytes and its insufficient regeneration is the major contributor in the pathogenesis of many cardiovascular diseases, including myocardial infarction, cardiac fibrosis and heart failure (Bergmann et al., 2009; Porrello et al., 2011b; Mollova et al., 2013). In fact, the injury induced adult myocardial tissue remodeling results from the lack of cardiomyocytes replenishment, while the neonatal and fetal myocardial tissues retain its contractile tissue from the proliferation of pre-existing cardiomyocytes after injury (Porrello et al., 2011b). This is mainly due

In humans there is a relation between left ventricular mass and cardiovascular mortality and morbidity independent of the blood pressure.5,6,7 In normal blood pressure subjects left ventricu-lar mass and diastolic filling have been found to be positively correlated with urinary sodium excretion8,9 and in two other normal BP groups followed up for 3 to 8 years the initial left ventricular mass and wall thickness were significantly related to the subsequent development of hypertension.5 Normotensive rats given 1% saline for several weeks develop an increase in heart weight due to an increase in left ventricular mass without an increase in blood pressure.10,11 In both normotensive humans and the rat therefore, left ventricular

I am a NP currently working for a Hospital Medicine group in an inpatient setting. My primary job responsibilities are to admit patients into the hospital, round on patients, provide cross cover on the patients on our service, provide cross cover on inpatients who our group is consulted to see, respond to rapid response codes, and occasionally discharge patients.

Atrial Septal Defect(ASD) is a very large problem concerning the heart in its overall function. When the heart, being the core of the cardiovascular system, has issues; it effects the rest of the body as a result. The core of the problem resides in the atrial septum. Normally the heart is divided into four separate chambers. But a person with atrial septal defect has an atrial septum that allows the blood from the left side of the heart back into the right side. This results in increased pulmonary blood flow and diastolic overload of the right ventricle. By having this constant left-to-right shunt, it can alter the pulmonary vascular resistance leading to hypertension or even the reversal of the shunt itself.

Patent ductus arteriosus (PDA), one of the more common cardiac defects at birth, is the persistence of an opening between the pulmonary artery and the descending thoracic aorta. This opening is as a result of failure of the physiological fetus ductus arteriosus to close, which normally occurs soon after birth. This hole allows for oxygenated blood from the aorta to mix with oxygen-depleted blood from the pulmonary artery. As a consequence, significant strain is placed on the heart and pressure within the lungs’ arteries is dramatically increased.
