Congestive Heart Failure occurs when the heart's pumping or filling function is impaired, reducing blood flow to meet the body's needs and, in many patients, increasing pressure within the heart and blood vessels. Fluid may accumulate in the lungs, legs, abdomen, or other tissues, resulting in symptoms commonly described as congestion.
Timely diagnosis and treatment can help control symptoms, reduce fluid congestion, slow disease progression, improve functional capacity, and reduce the risk of hospitalisation and other complications. Treatment depends on the type and severity of heart failure and may include medicines, lifestyle measures, treatment of the underlying cause, implanted devices, procedures, or advanced therapies.
Causes
Risk Factors
Cardiac Resynchronisation Therapy (CRT): A specialised pacemaker-based treatment that coordinates the contractions of the heart's ventricles. It may benefit selected patients with reduced ejection fraction, a prolonged QRS duration, and specific electrical conduction abnormalities..
Implantable Cardioverter-Defibrillator (ICD) : Device implantation tailored for primary or secondary prevention of sudden cardiac death from ventricular tachyarrhythmias.
Coronary Artery Bypass Grafting (CABG) : Open-heart surgery in which a surgeon uses a healthy blood vessel from another part of the body to route blood around the blocked artery.
Transcatheter Aortic Valve Replacement (TAVR) : Replaces a narrowed aortic valve (aortic stenosis) using a catheter threaded through an artery, usually in the groin, avoiding open-heart surgery.
Patent Ductus Arteriosus (PDA) closure : It is a procedure performed to shut an abnormal, persistent vascular channel, the ductus arteriosus, that failed to close naturally after birth.

Left Ventricular Assist Device (LVAD) : A mechanical circulatory support (MCS) device that uses a battery-operated pump to help a weakened heart pump blood throughout the body. The most common device is a Left Ventricular Assist Device (LVAD), surgically attached to the left ventricle (the heart's main pumping chamber) to draw blood from the ventricle and pump it directly into the aorta.
Orthotopic Heart Transplantation : Surgery to replace a severely failing heart with a donor heart. It is considered for carefully selected patients with advanced heart failure when other treatments are insufficient and transplantation is appropriate.
