Tetralogy of fallot Introduction: Tetralogy of Fallot (TOF) is one of the most common congenital heart disorders (CHDs). This condition is classified as a cyanotic heart disorder, because tetralogy of Fallot results in an inadequate flow of blood to the lungs for oxygenation (right-to-left shunt) (see the following image). Patients with tetralogy of Fallot initially present with cyanosis shortly after birth, thereby attracting early medical attention.

Tetralogy of Fallot

Louis Arthur Fallot, after whom the name tetralogy of Fallot is derived, was not the first person to recognize the condition. Stensen first described it in 1672; however, it was Fallot who first accurately described the clinical and complete pathologic features of the defects.


 The heart is a hallow muscular organ located in the center of the thorax where it occupies the space between the lungs (mediastinum) and rests on the diaphragm.  It weights approximately 3oogrms (10.6oz) the weights and size of the heart are influenced by age, gender, body weight, extent of physical exercises and conditioning and heart disease.  The hart pumps to the blood to the tissues, supplying them with oxygen and other nutrients.  The heart composed of 3 layers  The inner layer or endocardium consists of endothelial tissue and lines the inside of the heart valves.  The middle layer or myocardium is made up of muscles fibbers and is responsible for the pumping action.  The exterior layer of the heart is called the epicardium.  The heart is encased in a thin fibrous sac called the pericardium, which is composed of to layers.  Adhering to the epicardium is the visceral pericardium  Enveloping the visceral pericardium is the parietal pericardium, tough fibrous tissues that attaches to the great vessels, diaphragm, sternum and vertebral column and supports the heart in the mediastinum.  The space between 2 layers (pericardial space) is normally filled with about 20ml of fluid which lubricates the surface of the heart and reduce friction during systole.

FUNCTIONS OF THE HEART: Electophysiogic properties: The cardiac electrophysiologic properties of cardiac muscle regulates the heart rate and rhythm. The properties of cardiac include:  Exacitability  Automaticity  Contractility  Refractoriness  Conductivity

Exacitability: the ability of cardiac muscle cells to depolarize in response to stimuli/responses to electrical impulses Automaticity: ability to initiate an electrical impulse. Ability of cardiac pacemaker cells to initiate an impulse spontaneously and repetitively with out external neuro hormonal control. Contractility: the heart muscle is composed of long narrow cells or fibers. The action of potential initiates the muscles contraction by releasing calicium through the tubules of the cell membrane. Refractoriness: refractoriness is the heart inability to response to a new stimulus while still in a state of depolarization from an earlier stimulus. Conductivity: ability to transmit an electrical impulses from one cell to another.

DEFINITION: Heart failure is a significant cardiac functional disorder that can results in reduced oxygen delivery to the body’s organs tissues. The in ability of heart to supply blood circulation for the body needs. Heart failure is an abnormal clinical condition involving impaired cardiac pumping. It results in the characteristics pathophysiologic changes of vasoconstriction and fluid retension. Heart failure formerly called as congestive heart failure. Heart failure I not a disease.

INCIDENCE: Heart failure is association with high rest of morbidity, mortality and economic costs. In hospital mortality for these patients is 4% with a men length of hospital stay of 6.5 days. Hospital re-admission for 20 to 30 days 50%at 6 to 12 months mortality rate increases. Heart failure can affect both women and men alough the mortality is higher among women Heart failure affects about 5million people in U.S with 5000,000 new cases diagnosed each year It is mainly affected in aging people age below 75 years of age. In India mainly affected 33% of people in the year diagnosed as chronic heart failure.

ETIOLOGY AND RISK FACTORS: The performance of heart depends on 4 essential components: 1) Contractility of the muscle

2) Preload (amount of blood in the ventricles at the end of diastole) 3) After load (the pressure against which the left ventricles ejects) 4) Heart rate The causes of heart failure can be divided into 3 subgroups  Abnormal loading conditions  Abnormal muscle function  Conditions or disease that limit ventricular filling

Abnormal loading condition: conditions that increases preload

conditions that increases after load

 Regurgitation of mitral or tricuspid  Hypertension valve  Hyper volemia

 Pulmonary or systemic aortic or plumonic stenosis

 Congenital defect (left-right shunts)  High peripheral vascular resistance  Ventricular septal defect  Atrial septal defect  Patent ductus arteriosus

Abnormal muscle function:  Myocardial infraction  Myocarditis  Cardiomyopathy  Ventricular aneurysm

 Long term alcohol consumption  Coronary heart disease  Metabolic heart disease  Endocrine heart rate Limited ventricular filling:  Mitral or tricuspid stenosis  Cardiac tamponade  Constrictive pericarditis  Hypertrophic obstructive cardiomyopathy

Causes of heart failure: chronic heart failure

acute heart failure

 Coronary heart disease

 Acute myocardial infraction

 Hypertension

 Dysrhythmias

 Rheumatic heart disease

 Pulmonary mboli

 Congenital heart disease

 Thyrotoxicosis

 Corpulmonale

 Hypertensive crises

 Cardiomyopathy

 Rupture of papillary muscle

 Anemia

 Ventricle septal defect

 Bacterial endocarditis

 Myocarditis.

 Val uvular disorder

RISK FACTORS:      

Primary risk factor CAD and advancing age Hypertension Diabetes mellitus Cigarette smoking Obesity High serum cholesterol level.

PATHOPHYSIOLOGY: The cause(s) of most congenital heart diseases (CHDs) are unknown, although genetic studies suggest a multifactorial etiology. A study from Portugal reported that methylene tetrahydrofolate reductase (MTHFR) gene polymorphism can be considered a susceptibility gene for tetralogy of Fallot. Prenatal factors associated with a higher incidence of tetralogy of Fallot (TOF) include maternal rubella (or other viral illnesses) during pregnancy, poor prenatal nutrition, maternal alcohol use, maternal age older than 40 years, maternal phenylketonuria (PKU) birth defects, and diabetes. Children with Down syndrome also have a higher incidence of tetralogy of Fallot, as do infants with fetal hydantoin syndrome or fetal carbamazepine syndrome. As one of the conotruncal malformations, tetralogy of Fallot can be associated with a spectrum of lesions known as CATCH 22 (cardiac defects, abnormal facies, thymic hypoplasia, cleft palate, hypocalcemia). Cytogenetic analysis may demonstrate deletions of a segment of chromosome band 22q11 (DiGeorge critical region). Ablation of cells of the neural crest has been shown to reproduce conotruncal malformations. These abnormalities are associated with the DiGeorge syndrome and branchial arch abnormalities. The hemodynamics of tetralogy of Fallot depend on the degree of right ventricular (RV) outflow tract obstruction (RVOTO). The ventricular septal

defect (VSD) is usually nonrestrictive, and the RV and left ventricular (LV) pressures are equalized. If the obstruction is severe, the intracardiac shunt is from right to left, and pulmonary blood flow may be markedly diminished. In this instance, blood flow may depend on the patent ductus arteriosus (PDA) or bronchial collaterals.

BOOK PICTURE CLINICAL MANIFESTATION: The manifestations of heart failure depends on the specific ventricular involved the precipitating cause of failure, the degree of impaired, the rate of progression the duration of the failure and the clients underlying conditions. The signs and symptoms of heart failure can be related to which ventricles are affected. Left sided heart failure causes different manifestations then right sided heart failure. In chronic heart failure. Patient may have right and left ventricular failure. left side heart failure:  Pulmonary congestion includes:dysnea, cough, pulmonary crackles low oxygen saturation levels heart sounds s3 or ventricular gallop detected on auscultation, orthopnea, paraxymal nocturnal dysnea, adventitious breath sounds heard in various areas of lungs, oliguria,

NURSING DIAGNOSIS: 1. Risk for Decreased cardiac output related to structural abnormalities of the heart. 2. Activity Intolerance related to imbalance in the fulfillment of oxygen to the body's needs. 3. Impaired growth and development related to inadequate oxygenation, tissue nutrisis needs, social isolation. 4. Risk for infection related to the general conditions is inadequate.

Theory application Roy’s adaptation model Introduction:  Sister callista Roy began her nursing career in 1963. After receiving B.Sc(N) noting from moult saint marry college.  1960receives Ms in nursing  1977 her doctorate in sociology  Roy’s model is characterised as a system theory with a strong analogies of intervention. General system: Due to set of organized components released to form a whole employee feedback cycle of input, through put, output.  INPUT: Input includes tensions adaption level (the range of stimuli to which persons adaptation early)

 THROUGH PUT: through put makes use of a person processes and effect ions. Process refers to control mechanism that a person uses as a adaptive system. Effectors refers to the physiologic function, self concept and role function involved in adaptation.  OUTPUT: output is the outcome of the system when system is a person. Output refers to person’s behaviour. Metaparadigm and RAM:  Human being:Person is a bio psychological being in constant interaction with changing environment and recipient the nursing care as living system  Environment: Environment and surrounding and effect the development and behaviour of the persons group. The internal and external are the part of the person’s environment. For ex: elderly person admitted to hospital all the conditions of influence on him/her.  Health: heath is a process whereby individual are striving to achieve their maximum potential. It can be seen in healthy people, exercises regularly, not smoking pay attention dietary pattern. It is a process to relieve acute and chronic illness and terminal stages of diseases & to control the sign and symptoms, to promote health of the persons by promoting adaptive responses. 

Nurses: the nurses to reduce the ineffective responses as output behaviour of the person. The nurse promotes the health in all life processes. The nurses suggested by the model include approaches aimed at maintaining adaptive responses that support the person’s effort to creativity use his or her coping mechanism. INPUT
