Case Background
V-clamp case sharing
At the beginning of the new year, we diagnosed the referral cases from Beijing.
The little protagonist of this time is a teddy dog. The male dog is eight and a half years old and weighs 3.92 kg
It was diagnosed as chronic valvular degenerative heart disease (MMVD) stage C, left atrial and left ventricular volume overload, and severe mitral regurgitation.
In the past, there was acute pulmonary edema, which was initially stable after hospitalization. He was arranged to Xinyu for further evaluation and surgical intervention.
Baby, the diameter of valve ring before operation was 21mm. The lesion areas were mainly A2 and P2. There were prolapse and flail in A2 and prolapse in P2. The range of lesions is very wide, with vcw of 13 * 5mm, which is an oval and extremely severe reflux area.
The whole operation process is smooth, and the operation time of implanted instruments is about 20 minutes. After operation, there were clipper echoes in A2 and P2 areas, vcw decreased to 4 * 2mm, Mr decreased by 60%, and reflux was significantly improved.

Follow-up & Insights
Mitral regurgitation is very common in small dogs in the elderly, with an incidence rate of 20-30%. In the United States alone, there are about 7.18 million mitral regurgitation dogs. The occurrence of the disease is related to breed, age and gender. The age of sick dogs is mostly distributed in 5 ~ l 6 years old. The disease rate increases with age, mostly in small dogs and male dogs.
Canine mitral regurgitation has characteristic night cough, night asthma, weakness, exercise intolerance or fatigue after exercise and excitement, prolonged recovery time, severe purple tongue color, syncope and so on. The survival time of dogs with severe mitral regurgitation is only 3-6 months.
The control effect of traditional drugs is general, which can only alleviate symptoms, can not be cured, and the condition will still gradually worsen. The monthly drug cost ranges from 2000 to 4000 yuan. Or valve replacement. The operation is difficult, high risk, high mortality and expensive. At present, only a few teams in the world have completed individual cases, which can not be popularized in a large area.
Shanghai Hongyu medical v-clamp minimally invasive surgery has high safety, small trauma and fast recovery. It does not need cardiac arrest and cardiopulmonary bypass. It cuts a 2-3cm incision in the precordial area, punctures the heart and sends instruments to complete mitral valve repair, reduces mitral regurgitation, and provides a new technical scheme for the treatment of canine mitral regurgitation.
