"Hong Kong Adventist Hospital-Stubbs Road" successfully placed a 70-year-old patient with severe tricuspid regurgitation on the "Transcatheter Bicaval Valves System" (Transcatheter Bicaval Valves System) in mid-August this year. Surgery is the first operation of its kind in Hong Kong, giving such patients an option other than thoracotomy.
Feng Yongkang, a consultant cardiologist at the hospital, said that this new technology uses the implantation of a heart stent to implant a unidirectional heart valve system into two veins connecting the right atrium, thereby improving symptoms and improving the quality of life of patients.
Dr. Feng Yongkang introduces the placement of the "Transcatheter Double Vena Cava Valve System" with a minimally invasive method (provided by the hospital)
Tricuspid atresia can cause edema, wheezing, and dyspnea
According to Dr. Feng Yongkang, blood returns from the superior vena cava and inferior vena cava to the right atrium, through the "tricuspid valve" to the right ventricle.
The tricuspid valve is like a "trap" that is responsible for controlling the flow of blood in one direction. Once the tricuspid valve is incomplete, blood may return to the right atrium, even the superior and inferior vena cava, causing edema and asthma. Even breathing is difficult.
The principle of the "transcatheter dual-vena cava valve system" is to use a cardiac catheter to implant a one-way valve in the superior vena cava and the inferior vena cava connecting the right atrium to prevent blood from returning.

The patient's heart function is poor and not suitable for traditional surgery
Dr. Feng pointed out that currently patients with severe tricuspid regurgitation can undergo Tricuspid Annuloplasty or Tricuspid Repair, or minimally invasive surgery to implant small metal clips. To relieve the symptoms.
However, the patient Ms. Cheng (pseudonym) was unable to accept the above-mentioned surgery due to factors such as her old age, poor heart function, and previous surgery. multiple choice.
The principle of the "transcatheter double vena cava valve system" is to use a cardiac catheter to implant a one-way valve in the superior vena cava and the inferior vena cava connecting the right atrium to prevent blood from returning and reduce the pressure of the vein to improve the patient's edema problem.

Surgery only takes up to 1.5 hours
The principle of the new technology is to use cardiac catheters to implant a one-way valve in the superior vena cava and the inferior vena cava connecting the right atrium to prevent blood from returning and reduce the pressure of the veins to improve the patient's edema problem.
It is a minimally invasive surgery, which can be completed in about 1.5 hours, and can help patients who cannot accept thoracotomy or whose tricuspid valve leaflets are too open.
Ms. Cheng said that the postoperative symptoms have improved significantly. "Breathing has become much smoother, and the edema has gradually disappeared. Now I don't need to take water-removing pills, and my quality of life has been greatly improved."
Hong Kong Adventist Hospital-Stubbs Road, in mid-August this year, successfully performed the "transcatheter double-vena cava valve system" operation for a 70-year-old patient with severe tricuspid regurgitation.

Not suitable for all patients with severe tricuspid regurgitation
However, Dr. Feng also pointed out that the new technology does not deal with the problem of the tricuspid valve, nor is it done once and for all. Patients still need to be monitored regularly by doctors.
The operation is not suitable for all patients with severe tricuspid regurgitation. Patients with right ventricular failure, or pulmonary hypertension and liver cirrhosis may not be suitable. Patients must first consult a doctor.
