Medical advancements have opened up newer, less invasive treatment options for treating serious heart valve conditions. Transcatheter Aortic Valve Implantation (TAVI) is one such innovation, which allows cardiologists to manage aortic valve stenosis, especially for patients who are not ideal candidates for open heart surgery. But how does TAVI compare to conventional surgical methods? Let’s explore the key differences, procedure steps, benefits, and risks of TAVI and open heart surgery.
TAVI, also known as TAVR or Transcatheter Aortic Valve Replacement, is a minimally invasive cardiac surgery used for treating aortic stenosis. This medical condition occurs when the aortic valve becomes narrowed due to calcium and plaque buildup. This narrowing of the aortic valve restricts blood flow from the heart to the rest of the body, leading to fatigue, chest pain, shortness of breath, or even heart failure if left untreated.
Unlike open heart surgery, TAVI does not require opening the chest or stopping the heart. Instead, cardiologists insert a collapsible replacement valve through a catheter, usually via the femoral artery (in the groin), and guide it to the heart using advanced imaging techniques. Once the new valve is positioned correctly, it expands and pushes aside the damaged valve, taking over its function of controlling blood flow.
If you are curious to know what actually happens during this advanced procedure, here are the general TAVI procedure steps
These steps are often completed within 1-2 hours, and patients typically spend only 3–4 days in the hospital afterwards.
TAVI is especially beneficial for:
Patients at low, intermediate, or high risk for open heart surgery are all considered potential candidates for TAVI based on thorough evaluation by experienced cardiologists in Bangalore and across India.
The benefits of TAVI surgery are numerous, particularly for patients who cannot tolerate traditional surgery:
This makes TAVI an excellent option for patients seeking minimally invasive cardiac surgery at a trusted heart hospital in Bangalore or other cities.
While TAVI is considered safe and highly effective, like any medical procedure, it carries potential risks:
Open heart surgery refers to a surgical procedure where the chest is opened, and the heart is exposed for operation. It is commonly used to repair or replace heart valves, correct congenital defects, and perform heart bypass surgery (also known as coronary artery bypass grafting or CABG).
During this procedure, the heart is typically stopped, and a heart-lung machine is used to maintain circulation. This method is more invasive and usually involves a longer recovery time and hospital stay.
Here’s a breakdown of the open heart surgery procedure for valve replacement or bypass:
This procedure may take several hours and usually requires a hospital stay of 7–10 days, followed by weeks of home recovery.
Despite being more invasive, open heart surgery has its advantages, especially for patients who require complex interventions:
These factors make it essential to evaluate whether a less invasive alternative like TAVI might be more suitable for the patient.
Let’s take a closer look at the comparison: TAVI vs. Open Heart Surgery.
Invasiveness | Minimally invasive | Highly invasive |
Incision | Small incisions (groin/chest) | Large chest incision |
Anaesthesia | Local or conscious sedation | General anaesthesia |
Recovery Time | 3–7 days | 6–12 weeks |
Hospital Stay | 2–4 days | 7–10 days |
Ideal For | Elderly or high-risk patients | Younger or low-risk patients |
In today’s world, patients have more choices than ever before when treating heart valve disease. TAVI has emerged as a breakthrough in minimally invasive cardiac surgery, offering a safer, faster alternative to traditional open-heart surgery, particularly for high-risk or elderly individuals.
That said, open heart surgery remains the gold standard for certain complex cases, especially in younger patients or when multiple heart conditions need to be addressed simultaneously. Both options carry their benefits and risks, and the best approach will always be the one that’s personalised to your medical needs.
TAVI has less risk of death and stroke, shorter hospital stays, and faster recovery—ideal for older or high-risk patients.
Those with severe frailty, active infection, unsuitable valve anatomy, or poor vascular access may not qualify.
TAVI is typically for patients aged ≥80, or ≥70 with comorbidities.
No. It’s minimally invasive and done under local anaesthesia. Most patients feel little to no pain.
