Overview

Keyhole Cardiac Surgery or minimally invasive heart surgery, involves making small incisions in the chest to reach the heart between the ribs.

With the help of minimally invasive heart surgery, a variety of heart conditions can be treated. Compared to open-heart surgery, this type of surgery may result in less pain and a faster recovery for many people.

Cardiac bypass surgeries, heart valve replacement or repair surgeries, congenital heart defect repair, and cardiac tumor excisions can all be performed through a keyhole incision.


Technique

Traditional cardiac surgeries involve cutting the chest bone (sternum) in the midline & reaching the heart, but in MICS, “no bone is cut” we enter from the space between the Ribs & reach the heart.

Depending upon the procedure to be done, we enter the chest either through the right thorax (chest) or left thorax (chest). In any case, an incision is approximately 3 inches in length, whereas in regular cardiac surgery where the bone is cut, it has approx 12 inches long incision (cut).

Benefits Of Keyhole Cardiac Surgery

Keyhole Cardiac Surgery has many benefits compared to open heart surgery. Following are some of the benefits:

  • Smaller incision or cut - It involves making smaller incisions or cuts
  • Less Scar - There are minimal or no scars, mostly hidden under the clothes.
  • Quick recovery - With MICS, the patient can recover very soon; mostly, it will take around 6-7 days.
  • Less infection rates - There are very few chances of infection rates.
  • Less hospital stay - The patient will be discharged soon, and the hospital stay time is significantly less.
  • Less pain after surgery - Compared to other surgery methods of surgeries MICS causes less pain and discomfort.

Drawbacks Of Keyhole Cardiac Surgery

As with every surgery there comes some level of disadvantages. Here are they-

1. Expensive: Keyhole (MICS) surgery needs different sets of equipment & set up in the operation theater. It also needs trained surgeons & staff. Moreover, this technique provides a good range of benefits to the patient so the MICS or keyhole surgery is more expensive than traditional cardiac surgery.

Moreover, this technique provides a good range of benefits to the patient, so MICS or keyhole surgery is more expensive than traditional cardiac surgery.

2. Complexity: Over the years since it was introduced into surgical practice, it has been seen that the duration of on-pump (heart-lung machine) or complete surgery is more in Keyhole Surgery as it is more complex.

Suitable candidate for Keyhole cardiac surgery

The following are crucial points that need to be taken care of while choosing this surgery

Selection Of Patient: Not all patients are suitable for keyhole surgeries, as this technique involves single lung ventilation. So any patient with Asthma or lung conditions is not ideal for MICS.

A) Lung disease:

B) Diffuse Coronary lesion: In early years of experience, diffuse coronary lesions, or severely calcified mitral valves, were not done by MICS. But now, by experience, we are doing such cases by keyhole approach. In the early years, only single vessel coronary bypass was done by MICS, but now we are doing triple bypass by cardiac keyhole surgery.

C) Anatomy of structures: For aortic valve surgery, the anatomy of the aorta in the chest is essential. The straight rising aorta behind the sternum (chest bone) is difficult to operate by keyhole approach, or if the aorta is narrow (<2.5cm diameter), it is difficult through the keyhole approach.

Safety With Mics (Keyhole Cardiac Surgery)

Over all these years, when we are doing keyhole cardiac surgery, results have been comparable with traditional cardiac surgery. Patient outcomes are better & the recovery has been remarkable.

Conclusion:

Conventional Heart Surgery has undergone extensive changes over the past decade. Our team is well equipped to undertake many isolated or combined cardiac valve surgeries & single or multiple coronary bypass surgeries using a keyhole approach without cutting any bone. By going through the complete patient & their disease profile, we formulate & provide the best possible surgical option to the patient keeping in mind the best possible outcome.
