A Second Chance for Failing Hearts: Transplants and Life-Saving Heart Support

The heart is a symbol of resilience and vitality. But when it begins to fail, the effects ripple across every aspect of life. End-stage heart failure is not a sudden event — it usually develops over time as conditions like coronary artery disease, diabetes, or hypertension gradually weaken the heart muscle. In India, where these conditions are on the rise, advanced heart failure has become an increasingly common and serious challenge.

Early stages of heart failure can often be managed with medicines, procedures, and lifestyle changes. But when the heart grows too weak to meet the body’s demands, it needs more than medical therapy alone. At this point, advanced interventions like heart transplantation, mechanical circulatory devices or life-support systems step in to give patients a second chance.

Heart Transplant: Replacing the Failing Heart

For patients with end-stage heart failure — despite guideline-directed medical therapy and appropriate device therapy — a transplant is often the most definitive treatment. The surgery involves replacing the diseased heart with a healthy donor heart to restore circulation and quality of life. Transplantation is not a single event; it’s a carefully orchestrated journey that begins with evaluation and continues with lifelong follow-up and immunosuppression.

Types of Heart Transplant

There are different approaches to heart transplantation, depending on the patient’s needs and donor availability:

• Orthotopic Heart Transplant: This is the most common type, where the patient’s failing heart is removed and replaced with the donor heart in the same position.

• Heterotopic (or “Piggyback”) Transplant: In selected cases — such as markedly elevated lung pressures or when the donor heart is marginal — the donor heart is connected alongside the native heart so both can work together.

• Combined Transplants: When severe heart failure coexists with advanced disease of other organs (most commonly lungs or kidneys), combined procedures such as heart-lung or heart-kidney transplants may be required. These are highly specialised surgeries performed at centers with advanced infrastructure and multidisciplinary expertise, such as Apollo Hospitals.

Behind every successful transplant is a coordinated program: careful patient selection, expert donor retrieval, precise surgical technique, advanced critical care, and vigilant long-term monitoring.

Mechanical Circulatory Support: Helping the Heart When It Can’t Cope

Not every patient can undergo an immediate transplant. Some may wait for a suitable donor; others may not be candidates due to age or co-existing conditions. Mechanical circulatory support (MCS) devices can stabilise patients, improve symptoms, and extend survival.

Common devices:

• Ventricular Assist Devices (VADs): Implanted pumps that support the left ventricle (LVAD), right ventricle (RVAD), or both (BiVAD). Modern VADs typically provide continuous blood flow and can be used as a bridge to transplant or as destination therapy when transplant isn’t an option.
• Intra-Aortic Balloon Pump (IABP): A catheter-based device placed in the aorta that inflates during diastole and deflates just before systole to improve coronary perfusion and reduce afterload. It is used for short-term support, for example in cardiogenic shock after a heart attack or around high-risk cardiac procedures.
• Total Artificial Heart (TAH): In rare cases where both ventricles are irreversibly damaged, the native heart is removed and replaced with a mechanical pump that performs the full function of the heart—usually as a bridge to transplant.

Choosing the right device depends on the severity and type of heart failure, right- vs left-sided support needs, co-morbidities, and transplant candidacy. Management requires specialised surgical and ICU care, rehabilitation, and ongoing monitoring to prevent complications such as bleeding, infection, thrombosis/embolism, stroke, device malfunction, and — for durable LVADs — anticoagulation management.

At Apollo Hospitals, Chennai, MCS is delivered within a structured heart-failure program. Patients are assessed by a multidisciplinary team, guided through device selection, and supported by advanced surgical infrastructure, specialised ICUs, and long-term follow-up. This coordinated approach ensures devices truly achieve their goals—bridging patients safely to transplant or offering a durable path to better quality of life.

Life-Support in Critical Moments: ECMO

When the heart—or the lungs—fail suddenly, life-support technologies can be lifesaving. Extracorporeal Membrane Oxygenation (ECMO) temporarily takes over the function of the heart and/or lungs outside the body, allowing them to rest and recover.

• Veno-arterial (VA) ECMO: Supports heart and lungs in severe cardiogenic shock or cardiac arrest.

• Veno-venous (VV) ECMO: Supports lungs only in severe respiratory failure.

ECMO can be a bridge to recovery, decision, surgery, or transplantation. It is one of the most advanced forms of life support and requires round-the-clock expertise. Apollo Hospitals, Chennai runs a dedicated ECMO program with the capability to support both adults and children with severe cardiac or respiratory failure.
