Professor Sun Hansong: CABG, Valve, and Advanced Heart Failure Surgery Specialist
Professor Sun Hansong is a senior cardiac surgeon, professor, doctoral supervisor, and director of the Surgical Management Committee at Fuwai Hospital in Beijing. His clinical work focuses on coronary artery bypass grafting, complex valve disease, minimally invasive adult cardiac surgery, end-stage heart failure, ventricular-assist devices, heart transplantation, and hybrid procedures.
Clinical and Academic Focus
- coronary artery bypass grafting;
- off-pump and complex coronary surgery;
- multivessel and left-main coronary disease;
- severe aortic and mitral valve disease;
- minimally invasive and thoracoscopic heart surgery;
- hybrid coronary and valve procedures;
- ventricular-assist devices;
- heart transplantation; and
- second opinions before high-risk cardiac surgery.
Coronary Artery Bypass Grafting
Coronary artery bypass grafting, or CABG, creates new routes for blood to reach heart muscle beyond blocked coronary arteries. Arterial or vein grafts are connected to the coronary circulation.
CABG may be favored for complex multivessel disease, left-main disease, diabetes with suitable anatomy, reduced heart function, or coronary lesions that are difficult to treat durably with stents.
The decision between bypass surgery, PCI, and medical treatment should consider anatomy, symptoms, ischemia, operative risk, expected durability, and patient goals.
Off-Pump Coronary Bypass
Off-pump CABG is performed on the beating heart without a heart-lung machine. It may reduce some complications in selected high-risk patients, but the technique must still achieve complete and durable grafting.
Professor Sun has extensive experience in off-pump coronary surgery. The choice between off-pump and conventional bypass depends on anatomy, hemodynamic stability, surgeon experience, and the need for other procedures.
Antiplatelet Treatment After CABG
Aspirin is commonly used after bypass surgery to support graft patency. Some patients may benefit from temporary dual antiplatelet treatment, but bleeding risk must be considered.
Professor Sun has contributed to clinical research comparing aspirin alone with aspirin plus clopidogrel after CABG. Patients should not change antiplatelet medicine without their cardiac team.
Complex Valve Surgery
Severe aortic or mitral valve disease can cause breathlessness, fatigue, chest discomfort, fainting, pulmonary hypertension, or heart failure. Treatment may involve valve repair, replacement, catheter intervention, or observation.
Surgery is individualized according to valve anatomy, age, heart function, other cardiac disease, anticoagulation preferences, and expected durability.
Minimally Invasive Heart Surgery
Selected bypass and valve procedures can be performed through a smaller chest incision or with thoracoscopic assistance. Potential benefits include less tissue disruption and faster recovery, but not every patient is a suitable candidate.
A smaller incision should not compromise safety, graft quality, valve repair, or complete treatment.
Hybrid Cardiac Procedures
Hybrid treatment combines surgery with catheter-based intervention. Examples include minimally invasive bypass to a major coronary artery plus PCI to other vessels, or surgery combined with transcatheter structural treatment.
Planning requires coordinated review by cardiac surgeons, interventional cardiologists, imaging specialists, and anesthesiologists.
Ventricular-Assist Devices and Heart Transplantation
A ventricular-assist device supports circulation in selected patients with advanced heart failure. It may be used as a bridge to transplantation, a bridge to decision or recovery, or long-term therapy where approved.
Heart transplantation may be considered for severe irreversible heart failure when other treatment is insufficient. Eligibility depends on organ function, pulmonary pressure, infection, cancer history, adherence, psychosocial assessment, donor policy, and current hospital approval.
Who May Consider a Consultation?
- patients with complex multivessel or left-main coronary disease;
- patients comparing CABG and coronary stenting;
- patients with severe valve disease needing surgery;
- patients interested in a minimally invasive or hybrid approach;
- patients with reduced heart function needing high-risk revascularization;
- patients with end-stage heart failure considering mechanical support;
- patients seeking heart-transplant evaluation; or
- patients needing a second opinion after previous cardiac surgery.
Medical Records to Prepare
- a concise cardiac symptom and treatment timeline;
- coronary angiography and coronary CT in original DICOM format;
- echocardiography, transesophageal echo, and cardiac MRI;
- right-heart catheterization and functional testing when available;
- previous PCI, stent, cardiac-surgery, and implant records;
- recent blood count, kidney, liver, coagulation, glucose, lipid, and cardiac-biomarker results;
- vascular, lung, and frailty assessments;
- blood type, transplant, or mechanical-support evaluations when relevant;
- a complete medication list, especially antiplatelet and anticoagulant medicines; and
- a clear list of treatment and recovery goals.
Planning an International Consultation
Ongoing chest pain, severe breathlessness, fainting, shock, or rapidly worsening heart failure requires immediate local emergency care.
Stable patients should confirm whether original angiography and cardiac imaging can be reviewed. Remote medical-record review requires physician authorization. Final surgical, device, or transplant eligibility requires full in-person assessment and current institutional approval.
How CMCS Can Assist
CMCS – China Medical Concierge Shanghai is an independent medical concierge and health management company, not a hospital. We assist international patients with organizing and translating cardiac records, identifying an appropriate specialist, requesting appointment availability, arranging interpretation, and planning medical travel in China.
Access to Professor Sun, remote review, bypass surgery, valve surgery, mechanical support, or transplantation is subject to doctor and hospital approval. CMCS does not guarantee appointments, donor organs, device availability, surgical eligibility, or clinical outcomes.
