Professor Dou Kefei: Complex Coronary Intervention Expert in Beijing

Professor Dou Kefei: Complex PCI and Cardiovascular Metabolism Specialist

Professor Dou Kefei is a senior cardiologist, doctoral supervisor, director of the Internal Medicine Management Committee and Cardiovascular Metabolism Center, and deputy director of the Coronary Heart Disease Center at Fuwai Hospital in Beijing. His clinical and academic work focuses on complex coronary intervention, calcified lesions, left-main and bifurcation disease, physiology-guided PCI, and cardiovascular metabolic medicine.

Clinical and Academic Focus

  • complex coronary artery disease;
  • left-main coronary disease;
  • coronary bifurcation lesions;
  • heavily calcified coronary stenosis;
  • restenosis and stent failure;
  • physiology-guided PCI and QFR;
  • coronary disease with diabetes or metabolic disease;
  • high-risk and repeat coronary intervention; and
  • second opinions comparing PCI, bypass surgery, and medical treatment.

Complex Coronary Artery Disease

Complex coronary disease may involve the left main artery, multiple vessels, bifurcations, long segments, severe calcium, chronic total occlusion, or previously treated arteries. Treatment can include preventive medication, percutaneous coronary intervention, coronary bypass surgery, or a combination.

The best strategy depends on symptoms, ischemia, anatomy, heart function, diabetes, kidney function, surgical risk, bleeding risk, and patient priorities. Multidisciplinary heart-team review is particularly valuable when both PCI and surgery are reasonable.

Left-Main Coronary Disease

The left main artery supplies a large portion of the heart. Significant disease can carry substantial risk, but not every angiographic narrowing is functionally severe.

Assessment may use intravascular ultrasound or physiological testing. Treatment choice between PCI and bypass surgery depends on disease complexity, associated blockages, diabetes, heart function, operative risk, and the ability to take antiplatelet medicine.

Bifurcation Lesions

A bifurcation lesion occurs where one coronary artery divides into two branches. Stenting can affect both vessels and may require a provisional one-stent strategy or a planned two-stent technique.

Imaging and careful optimization help reduce underexpansion, branch loss, restenosis, and thrombosis. The technique should match the anatomy rather than follow one approach for every patient.

Calcified Coronary Lesions

Heavy calcium can prevent balloons and stents from expanding properly. Treatment may use specialty balloons, rotational atherectomy, intravascular lithotripsy, laser in selected cases, or a combination guided by OCT or IVUS.

Professor Dou’s team has also studied machine-learning approaches for predicting PCI success in moderate-to-severe coronary calcification. Predictive tools support but do not replace imaging and clinical judgment.

QFR and Physiology-Guided PCI

Quantitative flow ratio, or QFR, estimates the functional significance of a coronary narrowing from angiographic images without a pressure wire in selected cases. It can help identify lesions likely to benefit from intervention.

Professor Dou has contributed to major Chinese research on QFR-guided PCI. Image quality, vessel anatomy, microvascular disease, and clinical context affect interpretation.

Restenosis and Stent Failure

Recurrent narrowing after PCI may result from underexpansion, tissue growth, neoatherosclerosis, stent fracture, edge disease, or calcium. Intravascular imaging is often needed to identify the mechanism before treatment.

Options can include high-pressure dilation, drug-coated balloon treatment, another stent, plaque modification, or bypass surgery.

Cardiovascular Metabolic Medicine

Diabetes, obesity, high cholesterol, hypertension, fatty liver disease, kidney disease, and sleep apnea all influence coronary risk and outcomes after intervention. Long-term treatment should address these drivers rather than focus only on the stented segment.

Who May Consider a Consultation?

  • patients with left-main, multivessel, or bifurcation disease;
  • patients with severe coronary calcification;
  • patients whose previous PCI could not cross or expand a lesion;
  • patients with restenosis or stent thrombosis;
  • patients comparing PCI and coronary bypass surgery;
  • patients with coronary disease plus diabetes or metabolic disease;
  • patients seeking physiology- or imaging-guided treatment review; or
  • patients needing a second opinion before high-risk PCI.

Medical Records to Prepare

  • a concise cardiac symptom and treatment timeline;
  • coronary angiography in original DICOM format;
  • OCT, IVUS, FFR, iFR, or QFR reports and recordings;
  • coronary CT and ischemia-testing results;
  • echocardiography and cardiac MRI when available;
  • all previous PCI reports with stent type, size, and location;
  • recent blood count, kidney and liver function, lipids, glucose, and cardiac biomarkers;
  • bleeding, stroke, and contrast-reaction history;
  • a complete medication list, especially antiplatelet and anticoagulant medicines; and
  • a clear list of treatment goals and questions.

Planning an International Consultation

Ongoing chest pain, severe breathlessness, fainting, shock, or suspected heart attack requires immediate local emergency care. International travel must not delay urgent treatment.

Stable patients should confirm whether original angiography and intravascular imaging can be reviewed. Remote medical-record review requires physician authorization. Final procedure eligibility and strategy require complete cardiac assessment.

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 cardiovascular records, identifying an appropriate specialist, requesting appointment availability, arranging interpretation, and planning medical travel in China.

Access to Professor Dou, remote review, PCI, imaging, or a specific coronary device is subject to doctor and hospital approval. CMCS does not guarantee appointments, procedure eligibility, device availability, or clinical outcomes.

Important Note

Doctor titles, clinical roles, devices, procedures, and appointment arrangements may change. This profile is based on the supplied verified research document and is for general information only. It does not replace assessment by a qualified interventional cardiology team.
