Part 3: The Power of Preservation

Why “No Bone Cut” Means Faster Recovery

We’ve established that Totally Endoscopic Cardiac Surgery (TECS) uses tiny incisions (Part 1) and relies on high-tech 3D vision (Part 2). Now, we arrive at the most crucial physical distinction: the preservation of the patient’s foundational bone structure.

When a patient hears “minimally invasive,” they hope to avoid the trauma associated with open-heart surgery, particularly the splitting of the breastbone, or sternotomy. What is often misunderstood is that several of the minimally invasive approaches still involve some degree of bone manipulation.

The Hidden Cost of Bone Trauma

Any time the breastbone (sternum) is cut, or the ribs are aggressively spread, it introduces significant costs to the patient’s recovery: [Add a link to the HH article: 5 Things in Your Body that Heal Slowly when available]

1. Instability and Pain: Bone takes time to heal. A cut sternum must be wired back together and requires months to fuse. This healing phase is associated with significant pain, stiffness and discomfort.
2. Sternal Precautions: For about six to twelve weeks, patients are placed under strict restrictions and limited mobility. This means no driving, no lifting anything heavier than 5-10 pounds and avoiding pushing or pulling motions. These constraints drastically limit independence and lengthen the return to a normal lifestyle.

The Totally Endoscopic Advantage: Zero Bone Division

This is where the technique known as totally endoscopic cardiac surgery (TECS) truly earns the title of minimal.

The procedure is not just performed through a tiny incision; it is meticulously navigated through the natural spaces between the ribs. This crucial difference means:

• No Cutting of the Sternum: The breastbone remains completely intact.
• No Spreading of the Ribs: The keyhole port is placed strategically to avoid traumatic rib spreading.

This preservation of the rigid bony cage – the ribcage and sternum – is a game-changer. The entire chest wall remains structurally sound during and immediately after the procedure.

“Preserving the sternum and ribs is the single biggest determinant of a fast, pain-free recovery,” states Dr. Mario Castillo-Sang, a Cardiac Surgeon at St. Elizabeth. “When the chest wall is structurally intact, the patient can focus immediately on cardiac healing, not on the four-to-six-month process of bone healing.”

The Immediate Recovery Dividend

The benefit of avoiding bone division is immediate and profound. Because the chest wall is stable, patients undergoing TECS typically experience dramatically reduced pain and accelerated mobilization.

“The fact that patients don’t have sternal precautions means they leave the hospital with immediate independence. They can hug loved ones and move without fear of affecting their healing, which is invaluable,” notes Dr. Castillo-Sang.

The stability achieved by preserving the body’s natural architecture allows the patient to shift their energy away from healing a major structural wound and focus entirely on cardiac recovery.

In the next installment of this series, we will quantify this benefit by diving into the accelerated recovery timeline associated with TECS and what this means for a patient’s journey back to their life.
