Open-heart surgery is a complex procedure where surgeons treat the heart by opening the chest, typically through a sternotomy, to address various cardiac issues. Annually, approximately 2 million such surgeries are performed worldwide.

The primary reasons leading to these alarming cardiac conditions majorly revolve around lifestyle-related factors, such as smoking, poor diet, and lack of exercise, which contribute to atherosclerosis and other heart diseases. In this article, you will get detailed insights into the different types of open heart surgery and the procedures and recovery methods. Let’s get started!

Why is Open Heart Surgery Performed?

Open-heart surgery is mainly performed to address a variety of cardiac problems that cannot be properly controlled with less invasive procedures. One major cause is coronary artery disease, in which plaque buildup narrows or clogs the arteries that transport blood to the heart. In such circumstances, coronary artery bypass grafting (CABG) is performed to restore normal blood flow.

Another indicator is heart valve disease, which involves malfunctioning valves that impair regular blood flow. Surgeons may repair or replace the damaged valves to achieve appropriate heart function.

Congenital heart defects or structural disorders present at birth, often necessitate open-heart surgery to address irregularities and improve heart function. Furthermore, aneurysms—balloon-like bulges in the heart's arteries, may necessitate surgical treatment to avoid fatal ruptures.

In cases of severe heart failure and unresponsive to other treatments, procedures such as heart transplants or implantation of assistive devices such as pacemakers are performed during open-heart surgery to enhance cardiac output.

Overall, open-heart surgery is a critical procedure performed for various serious heart conditions, aiming to restore and maintain optimal cardiac health. Let's understand its types and procedures.

Open Heart Surgery Types

Open Heart Surgery Types and Procedure

(I) Types of Open-Heart Surgery

1. Coronary Artery Bypass Grafting (CABG)

This is the most common type of open-heart surgery which is used to treat blocked coronary arteries by bypassing them with a graft. This surgery aims to improve blood flow to the heart muscle.

2. Aneurysm Repair

This type of open-heart surgery repairs bulging or weakened sections of the aorta or other heart vessels. This is performed to prevent rupture and other life-threatening complications.

3. Heart Valve Repair or Replacement

This surgery fixes or replaces damaged heart valves (e.g., aortic or mitral valve). For this, the surgeons often use mechanical or biological (tissue) valves.

3. Congenital Heart Defect Surgery

In this type of open heart surgery, the surgeon corrects heart defects that are present from birth. This surgery aims to close holes in the heart (e.g., ASD, VSD) or repair abnormal heart structures that might impact blood circulation.

4. Left Ventricular Assist Device (LVAD) Implantation

This surgery is performed to implant an assistive device, a mechanical pump that supports heart function in patients with advanced heart failure. LVAD is sometimes used as a bridge to a heart transplant.

5. Heart Transplant

This complex surgery is done to replace a diseased heart with a donor's heart and is only performed in severe heart failure cases.

The Procedure of Open-Heart Surgery

Step 1: Pre-Surgery Preparation

In this heart surgery procedure, the doctor may advise certain important blood tests, imaging (echocardiogram, ECG), and other medical evaluations. Healthcare professionals may provide necessary instructions to stop certain medications (a few days) before surgery. Patients will need to stop alcohol intake or smoking as it may increase the risk of complications during the surgery and may delay the recovery process.

Step 2: During Surgery

In this step, the medical team administers general anaesthesia, ensuring the patient remains unconscious and pain-free throughout the procedure. Following this, a precise incision is made, typically along the sternum, to access the heart. In most cases, the patient is connected to a heart-lung machine, which temporarily takes over the heart’s pumping function to maintain circulation. The necessary surgical intervention is performed—whether it be repairing a defect, grafting a bypass, or replacing a valve. Finally, the incision is carefully closed using sutures or staples, marking the completion of the procedure.

Please note: The duration varies depending on the type of surgery performed. An open-heart surgery usually takes up to 6 or more hours.

Recovery After Open Heart Surgery

Heart surgery recovery is the most critical phase, where the patient begins to recover under the doctor’s close monitoring in the intensive care unit (ICU). During this period, important signs and heart functions are carefully observed to ensure stability. The hospital stay typically lasts between 5 to 10 days, depending on the patient’s condition and progress. Following discharge, a structured rehabilitation plan is given to the patient, including prescribed medications and necessary lifestyle adjustments, supporting long-term recovery and heart health.

Risks of Open Heart Surgery

Below are some of the potential open heart surgery risks:

Bleeding
Blood clots
Allergic reaction to anaesthesia
Damage to surrounding blood vessels
Stroke
Infections like Pneumonia, Endocarditis, Sternal Wound Infection (Mediastinitis), or even bloodstream infections.
Arrhythmias (irregular heartbeat)

Did You Know?

In rare cases, certain heart surgeries (such as some valve repairs) can be performed under regional anaesthesia (restricted to the specific area being treated), meaning the patient remains awake but pain-free.
During most open-heart surgeries, the heart is deliberately stopped, and a heart-lung machine takes over its function. Once the procedure is complete, surgeons use controlled electrical shocks or medication to restart the heart, bringing it back to normal rhythm.

Myths and Facts About Open Heart Surgery

Myth 1: Patients can never lead an active lifestyle after open heart surgery.
Fact: With proper rehabilitation, many patients return to normal activities, including exercise. Some even participate in sports and other physically demanding activities.

Myth 2: Recovery from open heart surgery takes years.
Fact: While complete recovery post open heart surgery varies by individual. Most patients resume normal activities within 6 to 12 weeks only after proper rehabilitation and strict lifestyle changes.

Myth 3: The survival rate in an open heart surgery is very low.
Fact: Advances in surgical techniques and post-operative care have significantly improved survival rates, with success rates exceeding 95% for many procedures.

Conclusion

Open heart surgery is a life-saving procedure that restores heart function and improves quality of life. While recovery takes time, proper post-operative care, expert rehabilitation, and certain lifestyle changes ensure the long-term heart health of the patient. With advancements in medical technology, success rates continue to improve, offering patients a better future.
