Overview of the Condition

What is Heart Failure?

Heart failure occurs when the heart cannot pump blood effectively. This may cause fluid buildup in the lungs and body, leading to symptoms such as shortness of breath, fatigue, and swelling. Common causes include high blood pressure, heart attack, and weakened heart muscles. Treatment includes medicines, lifestyle changes, and in severe cases, advanced therapies such as an LVAD or heart transplant.

Who is Commonly Affected?

Heart failure is a serious condition with significant health and economic burden worldwide. In India, heart failure accounts for about 65% of cases.

Causes / Why It Happens

• Coronary artery disease and heart attack
• High blood pressure (hypertension)
• Heart valve disease
• Myocarditis (heart muscle inflammation)
• Congenital heart disease
• Irregular heart rhythms (arrhythmias)
• Other medical conditions (diabetes, thyroid disorders, severe infections, blood clots, certain medicines)
• Lifestyle factors — smoking, excessive alcohol, ageing

Signs and Symptoms

• Shortness of breath during activity or while lying down
• Fatigue and weakness
• Swelling of the legs, ankles, feet, or abdomen
• Rapid or irregular heartbeat
• Reduced ability to exercise
• Persistent cough or wheezing
• Sudden weight gain due to fluid buildup
• Loss of appetite or nausea
• Difficulty concentrating or confusion
• Chest pain in some cases

Treatment Options

Tests Used to Diagnose Heart Failure

• Blood tests
• Chest X-ray
• Electrocardiogram (ECG)
• Ejection fraction (EF)
• Stress or exercise tests
• Cardiac CT or MRI

Procedures

• Coronary angiogram — detects blockages
• Myocardial biopsy — examines heart muscle in selected cases
• Left ventricular assist device (LVAD) — mechanical pump that helps the heart pump blood

Procedure Overview and Preparation

What is LVAD and Why is it Used?

LVAD is a mechanical pump used to help the heart circulate blood in patients with severe heart failure. It supports the heart's main pumping chamber. An LVAD may be used while waiting for a heart transplant or as long-term treatment. Although implantation requires major surgery, it can improve survival and quality of life in advanced heart failure.

Preparation Guidelines

• Inform the doctor about all medicines and allergies
• Stop eating and drinking several hours before surgery as advised
• Discuss the hospital stay and recovery support with family members
• Carry loose, comfortable clothing, eyeglasses, hearing aids, or dentures if needed
• You may need to stay in the hospital for a few days before LVAD surgery for evaluation

Step-by-Step

• The patient is connected to a ventilator to assist breathing
• A heart-lung bypass machine may be used to maintain blood circulation during surgery
• The surgeon makes an incision in the chest to access the heart
• The LVAD pump is attached to the left ventricle
• A tube connects the pump to the aorta to deliver blood to the body
• A driveline exits through the skin and connects the pump to an external controller and battery pack
• Once the device is functioning properly, the LVAD begins helping the heart pump blood

Time Required

4 to 8 hours.

Risks, Benefits and Hospital Stay

Risks and Complications

• Bleeding during or after surgery
• Blood clots, which may lead to stroke or device blockage
• Infection around the driveline or in the bloodstream
• Device malfunction requiring urgent medical attention
• Right-sided heart failure due to increased strain on the right side of the heart

Benefits and Expected Outcomes

• Improve the function of vital organs such as the kidneys, liver and brain
• Reduce symptoms like fatigue, breathlessness, and swelling
• Improve strength and ability to perform daily activities
• Help patients recover and return home from the hospital

Duration of Hospital Stay

14 to 21 days.

Recovery, Lifestyle and Follow-up

Recovery and Aftercare

Hospital stay after LVAD surgery is usually around 2 to 3 weeks, depending on the patient's recovery and overall condition. Some patients may require rehabilitation or additional care before returning home.

Lifestyle and Prevention

• Low salt intake
• Controlled fluid intake if advised
• Plenty of fruits and vegetables
• Gradual return to normal activities over several weeks to months
• Full adjustment to LVAD care often within a few months

Follow-up

Regular follow-up visits are essential after LVAD implantation to monitor device function and recovery. Appointments are usually frequent in the first few weeks and gradually reduce over time.
