The team implemented a comprehensive safety protocol with defibrillators and circulatory support on standby. Under ultrasound guidance, the catheter navigated through densely adhered vessels — first gently dilating with a small balloon, then precisely implanting the stent at the narrowest point of the main pulmonary artery.

The patient arrived in cardiogenic shock. Emergency teams immediately initiated monitoring, oxygen, and vasopressors. Coronary angiography revealed 99% left circumflex and 90% LAD stenosis. After IABP placement and pericardiocentesis confirmed heart rupture, Vice President Liu Zhigang led a triple surgery — pseudo-aneurysm repair, CABG, and PFO closure — successfully saving the patient's life.

A radiology nurse spotted the patient collapsing in the corridor and rushed him to the ER. Dr. Zhang Feng's team performed emergency angiography and stenting. When blood pressure plummeted with recurrent ventricular fibrillation, both IABP and ECMO were deployed simultaneously. The patient stabilized within a week.

After 2 months of pre-op treatment in Beijing, surgery was cancelled due to rising infection markers. In desperation, Zhang recalled President Liu's Douyin videos and made the journey in an ambulance equipped with IABP. President Liu implanted the HeartCon device under ECMO support. Zhang's words post-surgery: "I will live — for my parents, and for the medical team who saved me."

Director Miao Qi led the multi-disciplinary team through what was described as "defusing a bomb in a minefield." The team replaced the ascending aorta and valve, and performed coronary reimplantation. The surgery was flawless, and the patient recovered smoothly.

When reviewed at a major Japanese medical center, specialists were amazed: "This case is extremely rare. The first surgery was absolutely perfect — even our center would find it very difficult." The family chose to return to TEDANCD for the second surgery, even at their own expense.

Eisenmenger syndrome is often considered a "dead end" in cardiac surgery. Vice President Liu Zhigang's MDT team meticulously planned the surgery to prevent pulmonary hypertensive crises. Post-operatively, 24/7 ICU monitoring, daily MDT consultations, and personalized nutrition protocols led to a successful recovery.

To reduce complications from two separate surgeries, cardiac and vascular teams collaborated in a single session. Vascular surgeon Dr. Li Xuedong first placed the vertebral artery stent, then Director Miao Qi performed CABG and endarterectomy — a seamless relay that resolved both conditions.

Dr. Zhang described the minimally invasive approach as "performing surgery inside a snail shell" — the limited surgical field demands extraordinary precision, patience, and focus. TEDANCD now routinely performs thoracoscopic AVR, MVR, mitral repair, CABG, and congenital heart defect correction through minimally invasive approaches.

Dr. Zhang Feng explained: AFib makes the heart "race in neutral" like an engine — it pumps inefficiently, blood stagnates, the heart enlarges, and eventually fails. RF ablation corrects the electrical circuitry, allowing the heart to return to normal rhythm and giving exhausted myocardial cells a chance to recover.

Dr. Wang Yongde noted that conventional RF ablation requires fluoroscopy, which poses radiation risks for pregnant women and children. Zero-radiation ablation using 3D mapping + ultrasound breaks this barrier, marking a "green era" for arrhythmia treatment at TEDANCD.

EV-ICD combines the best of transvenous and subcutaneous ICDs with an innovative substernal electrode placement — no leads inside the heart or blood vessels. Pre-operative MDT planning included chest CT-guided electrode pathway mapping. The teenager has fully recovered and returned to school.
