The Coronary Artery Bypass Graft (CABG) Market is fundamentally segmented by the surgical method used, which dictates the complexity, recovery time, and utilization of cardiopulmonary bypass (CPB) machinery. The primary methods are On-pump, Off-pump, and Minimally Invasive Direct CABG (MIDCAB).

On-Pump CABG (Traditional Method):

• Market Dominance: The On-pump segment, which uses a heart-lung machine for cardiopulmonary bypass (CPB), traditionally holds a substantial market share. In 2024, the On-pump segment accounted for the largest revenue share, with some reports indicating around $66.80\%$.

• Clinical Rationale: This method is the primary approach for surgical revascularization, especially for complex and multivessel disease. Advancements in perfusion systems and integrated monitoring tools continue to reinforce its preference in challenging anatomical scenarios.

Off-Pump and Minimally Invasive Direct CABG (MIDCAB):

• Off-Pump: This technique performs the surgery on a beating heart without the use of CPB, often preferred by surgeons and patients for perceived benefits such as reduced risk of complications (e.g., stroke). However, market data varies, with some reports indicating On-pump dominance, while others report Off-pump holds the majority share (e.g., $54\%$ in 2024 in some reports).

• MIDCAB/Minimally Invasive: This segment is projected to grow at the fastest CAGR. The growing demand for less invasive cardiac procedures is driven by patient preference for shorter recovery times, reduced surgical trauma, less blood loss, and fewer incisions.

The market trend favors the adoption of minimally invasive techniques and robotic-assisted surgeries, which improve patient outcomes, reduce hospital stays, and enhance recovery times.
