Stentless Heart Valve Surgery

Cardiology (Open Heart Bypass Surgery)

The heart is made up of muscle tissue that supplies blood to the whole body. It is a pumping organ having four chambers. The upper two chambers are known as atria, and the lower chambers are known as ventricles. There are valves present in the chambers that keep blood flowing forward through the heart. These four types of valves are the tricuspid valve, mitral valve, pulmonary valve and aortic valve. Each valve has flaps. The flaps of tricuspid and mitral valves are known as leaflets and, the flaps of pulmonary and aortic valves are known as cusps.

When one of the four valves does not function properly or gets diseased or damaged, then a surgical process is performed to restore the functions of the heart. This procedure is known as heart valve surgery. In this surgery, the surgeons repair and replace the damaged heart or valve. The heart valve can be repaired using various surgical approaches like open-heart surgery or minimally invasive heart surgery.

Generally, in stentless heart valve surgeries, the stentless valves are used in pulmonary and aortic valve positions either as a full root replacement or in a sub-coronary position.

Indications Showing Need For Stentless Heart Valve Surgery

This surgery is required when the valves do not function properly. The need for this surgery arises when the patient with the damaged valves shows the following symptoms:

Types of Heart Valve Replacement

Underneath are the types of heart valve replacement surgeries in which artificial valves are used:

  • Aortic valve replacement - This surgery is performed on the aortic valve. The surgery is done if the patient is having a congenital disease that causes regurgitation or stenosis.

  • Mitral valve replacement - This surgery is recommended when the valve doesn't completely close or fully close. In this surgery, the damaged valve is replaced by a biological valve or artificial valve.

  • Double valve replacement - This replacement surgery is the replacement of both the aortic and mitral valve or the entire left side of the heart.

  • Pulmonary valve replacement - This surgery is required to treat the congenital defect, stenosis, which restricts the blood flow.

Risks Associated with Stentless Heart Valve Surgery

The possible complications that can arise during heart valve replacement surgery in rare cases, are listed below:

Diagnostic Tests Done Before Stentless Heart Valve Surgery

At Dr.Muthus Hospitals, an experienced team of doctors perform various diagnostic tests to determine whether the patient is eligible for the surgery or not. These tests are as follows:

  • Electrocardiogram (ECG) - This test detects the enlarged chambers of the heart, abnormal rhythms of the heart and heart diseases.

  • Chest X-ray - This imaging test helps the doctor in determining the size of the heart, heart valve diseases and condition of the lungs.

  • Cardiac MRI - In this test, radio waves and magnetic fields are used to get detailed images of the heart. The lower heart chambers are assessed through this test.

  • Cardiac catheterization - This is an invasive diagnostic test in which the imaging of coronary arteries is done using small tubes. The test helps evaluate heart functions and coronary artery diseases.

Procedure Of Stentless Heart Valve Surgery

At Dr.Muthus Hospitals, the following procedure is followed during the surgery:


The recovery period of the stentless heart valve surgery is between 4 to 8 weeks. At the time of discharge, the doctors will give instructions regarding the medications, exercise and wound care.

In heart valve replacement surgery, the damaged valve is replaced with biological or mechanical valves.

Dr.Muthus Hospital is best for stentless heart valve surgery. The multidisciplinary team of doctors perform this surgery with care. They use minimally invasive procedures during the surgery. The trained staff of the hospital provides comprehensive care to the patients during their recovery period.

The patient can resume his activities after getting recovered completely. The recovery process depends on various factors like the type of valve surgery, healing of the wound, energy level, etc. The patient can join a rehabilitation program to regain his energy.

The surgery may take two hours or more to get completed. The time of the surgery depends on the number of valves that need to be replaced or repaired.
