About Dr. K. Hema Krishna Sai (Sidhu)
Elaborated Introduction
Dr. K. Hema Krishna Sai (Sidhu) is a Consultant Cardiothoracic Surgeon and Head of the Department of Advanced Adult Cardiac and Minimally Invasive Cardiac Surgery at Capital Hospitals, Poranki, Vijayawada. Trained across premier institutions in India and having worked with the most eminent stalwart surgeons in the country, he blends surgical precision with compassionate, patient-first care—especially for individuals facing complex and high-risk heart conditions.
His clinical expertise spans coronary revascularization (off-pump, anaortic strategies, total arterial grafting, composite grafts with IMA/radial artery), advanced valve surgery (redo procedures, minimally invasive valve surgeries, aortic valve replacement, aortic root widening, mitral and double valve replacements, tricuspid valve repair), aortic procedures (ascending aorta, aortic root, hemi-arch and total arch replacement), and pericardial surgery (pericardectomy for constrictive pericarditis).
Dr. Sai is particularly well-versed in Minimally Invasive Cardiac Surgery (MICS), adopting small-incision approaches designed to reduce pain, support faster recovery, and enable earlier return to daily routines—while maintaining meticulous surgical standards. His approach emphasizes thorough pre-operative evaluation, clear communication with patients and families, and structured post-operative rehabilitation to support durable outcomes.
His professional formation includes MBBS from Dr. PSIMS & RF (Chinnautpally, Vijayawada), MS in General Surgery from Sri Ramachandra Medical College (Chennai), MRCS (Edinburgh), and MCh CVTS from Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), Thiruvananthapuram. Guided by the ethos “Redefining the limits of operability in high-risk cardiac surgery,” he is committed to precision, safety, and multidisciplinary teamwork within Capital Hospitals’ 24/7 cardiac care ecosystem. Languages spoken: Telugu, Hindi, English, Tamil, Malayalam, and French.
“Redefining the limits of operability in high-risk cardiac surgery” drives every consultation, procedure, and postoperative plan.

Minimally Invasive Cardiac Surgery (MICS)
Patient-Centric Precision
Benefits
- Smaller incisions and reduced scarring
- Less postoperative pain and opioid-free pathways
- Faster recovery with earlier ambulation
- Shorter hospital stays and earlier return to daily routines
Patient Explainer
Candidacy includes stable coronary anatomy, isolated valve lesions, or select redo operations. Preoperative imaging, functional assessment, and team planning ensure clarity. Expect defined perioperative milestones, focused pain control, and structured rehab.
A thorough preoperative evaluation includes risk stratification, anesthesia planning, and patient education. The surgery uses small incisions, specialized instruments, and often video assistance. Postoperatively, early mobilization, respiratory physiotherapy, and milestone-based discharge planning support durable recovery.
Selection depends on anatomy, comorbidities, and procedural goals. Multidisciplinary review, imaging, and patient preference guide whether MICS, hybrid, or conventional approaches deliver the safest outcome.
