What to Know About Left Ventricular Resection Surgery
Understanding ventricular resection: procedure details, effectiveness, risks, and outlook for heart failure treatment.
What is Left Ventricular Resection?
Left ventricular resection, also known as left ventricular reconstructive surgery or surgical ventricular restoration (SVR), is an open-heart surgery performed to treat heart failure by correcting an enlarged left ventricle, which is the main pumping chamber of the heart. The procedure typically involves removing damaged or scarred tissue and reshaping the left ventricle to restore a more efficient, elliptical shape for better blood circulation.
The term resection refers to the surgical removal of a part of an organ—here, the heart’s left ventricle.
Common types of ventricular resection procedures include:
- Surgical Ventricular Restoration (SVR)
- Ventricular Aneurysmectomy
- Left Ventricular (LV) Reconstruction
- The Dor Procedure
Ventricular resection may sometimes be combined with other heart surgeries, such as coronary artery bypass grafting (CABG) or valve repair, depending on the patient’s condition.
Why is Ventricular Resection Performed?
The primary goal of ventricular resection is to restore the heart to a more normal size and shape, thereby improving its ability to pump blood. Improved circulation can relieve the symptoms of heart failure, such as:
- Shortness of breath
- Swelling (especially in the legs, ankles, and feet)
- Fatigue
- Chest pain or angina
Ventricular resection is recommended for people whose heart enlargement is caused by conditions such as:
- Previous heart attack
- Dilated cardiomyopathy
- Hypertensive cardiomyopathy
This surgical intervention is not considered a cure for heart failure but offers significant improvement in symptoms and quality of life. Maintaining a healthy lifestyle after surgery is crucial for long-term outcomes.
How is Ventricular Resection Performed?
Ventricular resection is a type of open-heart surgery and involves several critical steps:
- The patient is placed under general anesthesia.
- The heart is temporarily stopped and connected to a heart-lung machine, which takes over the function of pumping blood and oxygen through the body during the operation.
- The surgeon makes an incision to open the chest and access the heart.
- If scar tissue or an aneurysm (a weakened, ballooned area in the heart tissue) is present, it is removed.
- The left ventricle is reshaped and reduced in size to restore an optimal, more elliptical pumping action.
- The heart is sutured, and blood flow is resumed once the procedure is complete.
The aim is to improve left ventricle ejection fraction (a measure of how much blood the ventricle pumps out with each contraction) and restore normal blood flow dynamics.

Recovery After Ventricular Resection
Recovery from ventricular resection involves careful medical supervision and gradual reintroduction to daily activities. Key aspects of recovery include:
- Monitoring in the hospital’s intensive care unit immediately after surgery
- Gradual increase in physical activity as advised by healthcare professionals
- Cardiac rehabilitation programs to promote optimal heart healing and educate on heart-healthy lifestyle choices
- Regular follow-up appointments with the cardiologist to monitor heart function and overall recovery
- Taking prescribed medications to support heart function and prevent complications
Patients may experience fatigue, discomfort, or temporary memory or cognitive problems, which often improve within a year of surgery. Recovery varies based on individual health factors and the complexity of the surgery.
Potential Risks and Complications
While ventricular resection can offer significant benefits for people with severe heart failure, like all major surgical procedures, it carries risks. The most common complications include:
- Infection at the incision site
- Inflammation
- Pneumonia
- Arrhythmias (irregular heartbeats)
- Excessive bleeding
- Damage to tissues and organs, including the heart or lungs
- Blood clots, which may lead to venous thromboembolism or stroke
- Memory or cognitive problems (typically short-term)
- Death (in rare, high-risk cases)
Risk level is influenced by the patient’s overall health prior to surgery. Individuals with very poor health, advanced age, or serious kidney dysfunction are at higher risk for complications and less favorable outcomes.
Effectiveness and Success Rates
Ventricular resection is often highly effective at improving heart function and quality of life in patients with heart failure due to an enlarged ventricle. Success is measured by increased left ventricle ejection fraction and reduction of heart failure symptoms.
The effectiveness and survival rates can depend on many factors, such as:
- The patient’s age
- Pre-existing health conditions (especially kidney function)
- Extent of heart enlargement
- Previous heart surgeries (like valve replacements)
- The procedure type (e.g., SVR vs. aneurysmectomy)
- Degree of ejection fraction improvement
| Years After Surgery | Survival Rate (%) |
|---|---|
| 1 Year | >90% |
| 5 Years | 71.9 – 78% |
| 10 Years | ≈48% |
| 15 Years | ≈26% |
While these survival rates may seem modest, it’s important to recognize that ventricular resection is reserved for patients with severe, life-threatening heart failure, where other therapies have failed.
Studies demonstrate that a successful ventricular resection can extend life span by up to 15 years and greatly improve daily functioning and well-being.
Factors Affecting Survival After Ventricular Resection
Several factors can influence survival and long-term outcomes post-surgery, including:
- Older age
- Impaired kidney function (high creatinine levels)
- History of valve replacements
- Problems with the right ventricle
- Overall health status and fitness
- Preoperative ejection fraction levels
- Type of ventricular resection performed
Close monitoring and management of these factors—both before and after surgery—are crucial to maximize survival and enhance recovery.
Tips for Recovery and Post-Surgical Heart Health
After a ventricular resection, recovery is an ongoing process. Key elements for optimal health post-surgery include:
- Taking prescribed medications exactly as ordered by your healthcare provider
- Attending cardiac rehabilitation sessions
- Eating a heart-healthy diet low in sodium, added sugars, and unhealthy fats
- Quitting smoking and avoiding tobacco
- Staying physically active according to your doctor’s guidance
- Managing stress through techniques like meditation, breathing exercises, and counseling
- Getting quality sleep for body and mind healing
Regularly scheduled follow-up appointments with your cardiologist are vital to track recovery, adjust medications, and identify any symptoms that may need attention.
When to Contact Your Doctor
After ventricular resection, it is important to watch for symptoms that may signal complications. Contact your healthcare provider if you experience:
- Increasing chest pain or palpitations
- Persistent shortness of breath
- Unusual swelling in the legs, ankles, or abdomen
- High fever or signs of infection at the incision site
- Sudden confusion, difficulty speaking, or weakness
- Persistent coughing or wheezing
Prompt action in response to these symptoms can help prevent severe complications and support long-term recovery.
Comparing SVR to Other Treatment Options
Several treatment modalities for enlarged or damaged left ventricles exist, but surgical ventricular restoration (SVR) and similar procedures are generally reserved for severe cases. According to recent studies:
- Coronary artery bypass grafting (CABG) combined with ventricular resection offers better outcomes and higher survival rates than non-surgical options like medication or percutaneous coronary intervention in cases of ventricular aneurysm.
- Modern heart failure therapies, including advanced medications and device therapies, are reducing the need for ventricular resection surgeries overall.
Each treatment plan is highly individualized, depending on the patient’s specific anatomy, previous heart events, and overall health status.
