Minimally Invasive Heart Valve Surgery: Less Pain, Faster Recovery

Cost primarily depends on two things: which valve is used — mechanical valves are significantly less expensive than tissue valves, and among tissue valves, third-generation valves cost more than second-generation ones — and the patient's clinical course, since a straightforward surgery without a long hospital stay or comorbidities costs less. The average cost generally starts from $9,000 and goes up to $15,000–$16,000.

Cardiac tumours in children are well known, though this exact pathology is not very common. The echo gives us an idea, but I would suggest also doing an MRI and a CT to further delineate it. I would like the details of this patient sent to our institute so we can forward it to our paediatric cardiac surgeon, since paediatric cardiac surgery is a separate subspecialty from the adult cardiac surgery I practise, and we do have a dedicated paediatric cardiac surgical team. This child needs very close follow-up and further investigation.

Tetralogy of Fallot is one of the commonest surgical procedures, and the outcome depends on the exact anatomy delineated by a proper paediatric echo, but six years is not a very late stage — in India a lot of patients are operated on at this age or even older. The outcome of tetralogy repair even at 6 years is excellent, so this patient certainly needs surgical correction.

Myocardial bridging is not uncommon and is often seen on angiography. If it is asymptomatic, nothing needs to be done. If it is symptomatic, we normally do a stress thallium test — if positive, we recommend surgery; if negative, which is most of the time, only medical treatment is needed. If it is only myocardial bridging with no stenosis involved in other arteries (the circumflex or right coronary artery are normal), nothing needs to be done, but if the stress test is positive, surgery is recommended.

Tetralogy of Fallot is one of the commonest procedures in paediatric cardiac surgery, alongside ASD and VSD repair. It is a very commonly performed procedure with excellent outcomes — any paediatric cardiac centre does this routinely, and the clinical outcomes are excellent.

Minimally invasive heart valve surgery reduces pain, improves the cosmetic result, shortens hospital stay, speeds up recovery and reduces the need for blood products compared with standard open heart surgery.

Two approaches are commonly used: a right anterior thoracotomy through the second intercostal space that avoids a sternotomy entirely, and mini AVR, which uses an upper partial sternotomy instead of a full sternotomy, leaving the sternum more stable.

For mitral valve replacement, the minimally invasive approach used is a right anterior thoracotomy through the fourth intercostal space, which avoids the more visible frontline scar of a standard median sternotomy.

Many patients needing valve repair or replacement are young and in their productive working years and cannot afford to stay away from work for long periods, so a faster recovery and shorter hospital stay are especially valuable to them.
