Minimally Invasive Direct Coronary Artery Bypass
Introduced MIDCAB in the Permian Basin.
At the heart of surgery.
At the edge of possibility.
A surgeon’s perspective. An innovator’s questions. A continuing pursuit of wider access.
THE SURGEON
A smaller incision.
A new direction.
Dr. Srivastava’s surgical work spans minimally invasive coronary artery bypass, ThoraCAB and beating-heart totally endoscopic coronary artery bypass—TECAB.
His exploration of these techniques took him from single-vessel to multivessel procedures, and from his own operating room to teaching surgical teams internationally.

Milestones in
beating-heart surgery.
Each chapter opened another avenue for surgical practice and teaching.
Heart Port technique
Performed coronary artery bypass grafting with five grafts using the Heart Port Technique.
Development of ThoraCAB
Developed and introduced coronary artery bypass surgery on a beating heart through a lateral thoracotomy incision.
Robotic cardiac surgery
Introduced robotic surgery in the Permian Basin. Performed arrested-heart TECAB in Texas and beating-heart TECAB at Escorts Heart Institute and Research Center in New Delhi.
Beating-heart TECAB
Performed beating-heart totally endoscopic coronary artery bypass in North America.
Double- and triple-vessel TECAB
Performed double-vessel beating-heart TECAB to LAD and OM, and LAD and RCA, alongside triple-vessel revascularization to LAD, DX and OM.
Hybrid revascularization
Performed beating-heart TECAB with simultaneous angioplasty / stent in the operating room. Performed TECAB LIMA to LAD with concomitant aortic valve replacement.
Quadruple-vessel bypass
Performed quadruple-vessel bypass on a beating heart.
Robotic cardiac surgery in India
Performed single- and double-vessel TECAB and robotic myxoma excision.
THE INNOVATOR
From surgical experience
to engineered possibility.
Each innovation begins with a clinical challenge: extending specialist expertise, improving access, supporting surgical teams or rethinking where an operating room can exist.
Robotic surgical platform
Designed around the work of surgery.
Dr. Srivastava brought his experience in robotic cardiac surgery to the development of SSI Mantra. The SS Innovations team developed the platform with affordability and wider access at the heart of its mission.
Commercial platform1 / 7
An operating-room perspective, carried into every project.
Years of cardiac surgery, robotic programme development and surgical training shaped the questions behind these initiatives: how to extend specialist expertise, simplify demanding workflows and bring advanced surgical capability closer to where it is needed.
These projects bring together Dr. Srivastava’s clinical perspective and leadership with the work of SS Innovations’ research, engineering and clinical teams.

BUILDING CAPABILITY
Beyond a
single surgeon.
Developing a surgical program means sharing experience with a team. Teaching and program building have accompanied Dr. Srivastava’s work across North America, Asia and Australia.
