Symptoms

What Symptoms Might an LVAD Patient Experience?

Patients living with a Left Ventricular Assist Device (LVAD) may experience a range of symptoms related to their underlying heart condition, the presence of the mechanical device, or potential complications. These symptoms are often grouped into categories for easier understanding and management.

1. Common and Expected Symptoms

These are typical for individuals with an LVAD and usually do not indicate serious problems:

• Absence of a detectable pulse: Most LVADs produce a continuous blood flow, which can result in a faint or unmeasurable pulse.
• Low blood pressure readings: Patients often have a mean arterial pressure (MAP) between 60–90 mmHg.
• Fatigue: Tiredness is common as the body adjusts to the device and ongoing heart failure.
• Dizziness or light-headedness: This may occur due to changes in blood pressure or volume.

2. Warning Signs That Require Medical Attention

Some symptoms may suggest complications and should not be ignored:

• Signs of infection: Redness, swelling, warmth, or drainage at the driveline site, or symptoms like fever and chills.
• Bleeding issues: May occur due to blood thinners. Watch for dark or bloody stools, vomiting blood, or signs of anemia.
• Possible stroke symptoms: Sudden confusion, trouble speaking, weakness on one side—these could be signs of a blood clot.
• Device malfunction indicators: If the LVAD alarms go off, or if you notice fatigue, breathlessness, or dizziness, it might signal a pump issue.
• Heart failure symptoms returning: Swelling in the legs or abdomen, shortness of breath, or increasing fatigue might mean the right side of the heart is struggling.
• Irregular heartbeats (arrhythmias): These may cause fainting, palpitations, or dizziness.
• Low flow alarms: These can result from dehydration, internal bleeding, or pump obstruction.

3. Emergency Symptoms – Seek Immediate Help

Some symptoms are considered urgent and require emergency care:

• Severe chest pain or breathlessness: Could indicate pump failure, a blood clot in the lung, or a heart attack.
• Loss of consciousness: May be due to a stroke, device failure, or low blood pressure.

Preparation for LVAD Surgery

Getting ready for Left Ventricular Assist Device (LVAD) surgery involves careful planning, detailed medical evaluations, and choosing the right care provider. Here’s what patients can expect during the preparation phase:

1. Choosing the Right Medical Facility

Start by selecting a reputable hospital in India that specializes in advanced cardiac procedures like LVAD implantation. Cost, surgeon experience, and hospital infrastructure play a major role in successful outcomes.

2. Preoperative Medical Evaluation

Before the surgery, a complete set of tests is required to assess heart function and overall health. This includes:

• Blood tests
• Electrocardiogram (ECG)
• Echocardiography (ECHO)
• Urine tests
  These tests help determine if the patient is medically fit for the procedure.

3. Informed Consent

The patient or family must sign a formal consent document authorizing the medical team to perform the surgery.

4. Medication Review

Inform the healthcare team about any current medications, including over-the-counter drugs or supplements. Blood thinners, in particular, are usually stopped at least 7 to 10 days before surgery to reduce the risk of excessive bleeding.

5. Hospital Admission

Admission typically occurs a day or two before the operation. Patients are usually asked to fast—avoiding food and drink for several hours before surgery.

6. Post-Angioplasty Monitoring (If Applicable)

If the patient has undergone a recent angioplasty, they may need to remain under observation in the hospital for at least one night.

7. Understanding the Cost

The cost of LVAD surgery in India can range from approximately USD 80,000 to USD 100,000. This variation depends on factors like the hospital’s location, surgeon’s expertise, and the type of device used.

 

Procedure

LVAD Implant Procedure

Before undergoing Left Ventricular Assist Device (LVAD) implantation, patients are thoroughly counseled by the surgical and anesthesia teams regarding the expected benefits and potential risks. The procedure is complex and typically requires open-heart surgery under general anesthesia.

Step 1 – Administering Anesthesia

The surgery begins with the administration of general anesthesia to ensure the patient remains unconscious and pain-free throughout the operation. LVAD implantation generally takes between 5 to 7 hours.

Step 2 – Making the Incision

To access the heart, the surgeon makes a vertical incision along the chest. The breastbone (sternum) is then carefully opened to expose the heart.

• The patient is connected to a heart-lung bypass machine, which maintains circulation and oxygen supply during the procedure.
• A ventilator is used to manage the patient’s breathing while the surgery is underway.
• Because the operation is major and tailored to each individual’s condition, recovery time and hospital stay vary from patient to patient.

Step 3 – Implanting the Device

The LVAD is surgically connected to the left ventricle and the aorta. The pump is placed inside the chest, and a driveline (a cable that connects the device to an external power source) is guided through the abdominal wall.

Step 4 – Closing the Incision

After securing the LVAD in place, the surgeon closes the chest using medical sutures, surgical staples, or skin adhesives. The skin is then sealed, and the patient is moved to a specialized cardiac care unit for recovery and monitoring.
