A congenital heart defect is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. They can disrupt the normal flow of blood through the heart. The blood flow can slow down, go in the wrong direction or to the wrong place, or be blocked completely.

Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons. It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, and atherosclerosis. It also includes heart transplantation.

Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. In some cases, the heart can't fill with enough blood. In other cases, the heart can't pump blood to the rest of the body with enough force. Some people have both problems. Heart failure develops over time as the heart's pumping action grows weaker. The condition can affect the right side of the heart only, or it can affect both sides of the heart. Most cases involve both sides of the heart. Heart failure is a very common condition. About 5.7 million people in the United States have heart failure. Both children and adults can have the condition, although the symptoms and treatments differ. The Health Topic focuses on heart failure in adults.

Many cardiac devices are designed to help control irregular heartbeats in people with heart rhythm disorders. These irregularities are caused by problems with the heart’s electrical system, which signals the heart to contract and pump blood throughout the body.

Cardiac nursing is a nursing specialty that works with patients who suffer from various conditions of the cardiovascular system. Cardiac nurses help treat conditions such as unstable angina, cardiomyopathy, coronary artery disease, congestive heart failure, myocardial infarction and cardiac dysrhythmia under the direction of a cardiologist. Cardiac nurses perform postoperative care on a surgical unit, stress test evaluations, cardiac monitoring, vascular monitoring, and health assessments. Cardiac nurses must have Basic Life Support and Advanced Cardiac Life Support certification. In addition, cardiac nurses must possess specialized skills including electrocardiogram monitoring, defibrillation, and medication administration by continuous intravenous drip. Cardiac nurses work in many different environments, including coronary care units (CCU), cardiac catheterization, intensive care units (ICU), operating theatres, cardiac rehabilitation centers, clinical research, cardiac surgery wards, cardiovascular intensive care units (CVICU), and cardiac medical wards.

A heart transplant, or a cardiac transplant, is a surgical transplant procedure performed on patients with end-stage heart failure or severe coronary artery disease when other medical or surgical treatments have failed. As of 2018, the most common procedure is to take a functioning heart, with or without transplanting one or both lungs at the same time, from a recently deceased organ donor (brain death is the standard) and implanting it into the patient. The patient's own heart is either removed or replaced with the donor heart (orthotopic procedure) or, much less commonly, the recipient's diseased heart is left in place to support the donor heart (heterotopic, or "piggyback", transplant procedure).

A case report on Cardiology gives an appropriate convention for all cardiologists by rendering their important clinical cases of late occurrence. Studying from medical cases provides valuable experience for clinicians, students and paramedical staff -members. Rare medical reports and conditions discovered through the latest methods of examination are energized. Moreover, studying diagnostic methods from medical cases and the interpretation of symptoms is significant to train and burgeon the thought processes which are being used in the clinical field.

Cardiovascular diseases as well as heart condition, arrhythmias and high blood pressure, is that the leading reason for morbidity and mortality globally. The prevention diagnosis and treatment of cardiovascular diseases. There are a unit various devastating conditions touching the centre and blood vessels, resulting in high demand for vas medicine. Cardiology disorders embrace in arteria diseases, heart failure and congenital heart defects.
