Bridging the Gap: Cost-Effective Modifications in Endoscopic Cardiac Surgery for Resource-Limited Settings

Endoscopic cardiac surgery represents a significant advancement in the field of cardiac care, offering patients reduced surgical trauma, faster recovery, and fewer postoperative complications.^1,2 However, its adoption remains limited in low-income and middle-income countries due to high costs, infrastructure deficits, and a lack of trained personnel. To address these challenges, pragmatic, low-cost modifications and strategic innovations are needed to make this transformative technology accessible and sustainable across resource-constrained settings.

One of the key barriers to implementing endoscopic cardiac surgery in low-resource hospitals is the high cost of specialized equipment. Traditional systems, including 3-dimensional (3D) endoscopic cameras, custom-designed instruments, and robotic platforms, are prohibitively expensive. An effective alternative is the use of high-definition 2-dimensional (2D) cameras, which provide sufficient imaging quality at a fraction of the cost. Studies comparing 2D and 3D systems in simulated settings have shown no significant differences in performance, underscoring the potential of 2D systems as a viable substitute. ³

Reusable surgical instruments are another essential component of cost reduction. With proper sterilization and maintenance protocols, high-quality instruments can be reused without compromising safety. In addition, local manufacturing of endoscopic tools tailored to regional needs can significantly reduce procurement costs while promoting domestic innovation and economic development.

An important innovation lies in the repurposing of existing laparoscopic instruments, such as graspers and needle holders, which are already available in many general surgical setups. These tools can be adapted for cardiac use with minor modifications, reducing the need for investment in new inventories.

Beyond hardware, capacity building is vital. Simulation-based training using low-cost materials—such as artificial tissues or animal heart models—allows surgeons to practice technical skills in a safe and affordable manner. ⁴ Moreover, telemedicine platforms and virtual mentorship programs can link surgeons in low-resource settings with global experts, enhancing learning opportunities without requiring international travel or expensive onsite training.

Standardization of protocols and task shifting can also streamline workflows and improve surgical efficiency. Training nonphysician personnel, such as nurses and technicians, to manage perioperative responsibilities allows experienced surgeons to focus on complex tasks. This multidisciplinary approach fosters better patient outcomes and optimal resource utilization. ⁵

Our experience with cost-saving strategies—such as performing totally endoscopic coronary artery bypass using 2D imaging and conducting endoscopic vessel harvesting with existing tools—demonstrates that excellence in surgical care is achievable with ingenuity and commitment, even in constrained environments.

Challenges such as regulatory hurdles, cultural acceptance, and infrastructure limitations remain. However, these can be addressed through public-private partnerships, international collaborations, and advocacy for supportive policies that recognize the long-term value of minimally invasive techniques in improving population health.

In conclusion, cost-effective adaptations in endoscopic cardiac surgery are not only feasible but imperative to advancing equitable health care. With innovation, dedication, and strategic implementation, resource-limited hospitals can bridge the gap in access to modern cardiac care and ensure that surgical excellence is not limited by geography or economy.
