Introduction
Over the past decade, minimally invasive cardiac surgery (MICS) has undergone a paradigm shift — transitioning from experimental procedures performed in select tertiary centres to reproducible, standardised techniques offered across high-volume academic institutions. At AVMC Medical College, our cardiac surgery unit has been at the forefront of adopting and refining these approaches.
Historical Context and Evolution
The roots of minimally invasive cardiac surgery trace to the mid-1990s, when pioneering surgeons began exploring port-access and limited sternotomy approaches for mitral valve repair.
Foundational developments in the early era
Between 2000 and 2010, significant improvements in endoscopic instrumentation, video systems, and perfusion cannulation strategies gradually resolved the limitations of early techniques.
Current Approaches at AVMC
Our unit currently performs minimally invasive procedures across the full spectrum of cardiac pathology including mitral valve repair, tricuspid valve annuloplasty and mini-thoracotomy bypass procedures.
VATS Procedures
- Video-assisted thoracoscopic cardiac surgery for valve procedures
- Endoscopic saphenous vein harvesting for CABG
- Minimally invasive Maze procedure for atrial fibrillation
Robotic Surgery
Robotic-assisted surgery has expanded the range of cases amenable to minimally invasive approach through enhanced dexterity and precision in small operative fields.
Clinical Outcomes and Data
Analysis of our prospective database reveals outcomes comparable to, and in several metrics superior to, conventional sternotomy in appropriately selected patients.
Challenges and Limitations
- Extended operative times during learning phase
- Peripheral cannulation risk considerations
- Not all anatomy is suitable for MICS
- Robotic cost remains high in many centres
Future Directions
The next frontier lies in convergence of robotics with imaging fusion, AI-assisted planning and augmented intraoperative guidance.
Conclusion
A decade of AVMCH experience affirms that minimally invasive cardiac surgery is now a mainstream, evidence-backed option for eligible patients.
