China News Online, September 21 (Chen Jing Yao Jun) A self-expanding valve is installed in the damaged heart valve to realize a "valve-in-valve".
The reporter learned on the 21st that experts from Shanghai Chest Hospital used international advanced interventional technology to successfully implant the "heart gate" for a 54-year-old patient, Aunt Liu.
It is reported that when Aunt Liu was born with a severe congenital heart deformity, when she was 18 years old, Professor Qiu Zhaokun, the chief expert of Shanghai Chest Hospital and Professor of Cardiac Surgery, performed surgical repairs on her.
At that time, few hospitals in China were able to carry out this kind of difficult operation.
Aunt Liu gained the same quality of life as a healthy person after the operation.
Since 2015, Aunt Liu, who is middle-aged and elderly, has had heart problems many times.
Since September this year, Aunt Liu began to feel heart discomfort again, and she was panting for walking and eating.
Pan Xin, director of the structural heart disease sub-specialty of Shanghai Chest Hospital, told reporters that through examination, the doctors found that Aunt Liu suffered from endocarditis with serious sequelae-the previously implanted valve was invaded and damaged by bacteria. Up.
The "heart gate" was completely damaged and severe pulmonary valve regurgitation caused the patient's heart to expand to twice the normal size.
If it is not handled in time, Aunt Liu's life is worrying.
During the consultation, the experts analyzed that they could only install a new "heart door" for Aunt Liu. However, it is no longer feasible to open the chest and replace the valve again.
The cardiology team proposed a "valve-in-valve" surgical plan.
Professor Ben Ben, the director of the heart center of the hospital, told reporters that "valve-in-valve" is like a Russian doll. The doctor installs a new self-expanding valve into the damaged valve through intervention.
The self-expanding flap, like an automatic umbrella, can be opened by itself when it reaches the position.
"Heart Gate" is selected, how to put it into the heart?
He Ben told reporters that "valve-in-valve" implantation places high demands on doctors' skills. At the same time, "valve-in-valve" implantation in the pulmonary artery will create a "Z-shaped" curve in the catheter path, which is even more challenging.
The expert team decided to use advanced interventional technology to make the special guide wire combination straighten and smooth the tortuous blood vessel path, allowing the "heart gate" to pass the "curve" smoothly.
According to the plan, the surgery team delivered the valve to the target location, opened it automatically, and embedded it in the previously damaged pulmonary valve.
The new "heart door" has been replaced.
"I cured my congenital heart disease here when I was 18 years old, and now I am 54 years old, and the experts from Shanghai Chest Hospital rescued me again." Aunt Liu on the hospital bed had a smile on her face.
It is understood that after the operation, Aunt Liu is recovering well and will be discharged soon.
