On November 20, the team of Prof. Chen Liangwan and Prof. Dai Xiaofu from the Department of Cardiac Surgery of Fujian Union Medical College Hospital successfully removed an artificial heart (left ventricular assist device, LVAD) implanted 2 years ago for a heart failure patient with recovered cardiac function, which is the first case of LVAD removal using percutaneous access occlusion surgery in Fujian Province. This procedure innovatively utilizes a non-invasive or minimally invasive approach that avoids the risk of reopening the chest and provides a new option for LVAD withdrawal therapy in patients with LVAD.

Prof. Chen Liangwan introduced that, with the passage of time, some patients' cardiac function has been fully recovered, at which time the LVAD needs to be withdrawn, or there are some complications of the LVAD, such as infections, bleeding, blood clots, device malfunctions, etc., which may need to be withdrawn from the LVAD. traditional LVAD withdrawal surgery needs to open up the chest again to remove the pump body and tubes on the heart, which is a high-risk surgery, and it may lead to serious consequences such as bleeding, infections, pericardial tamponade and so on. , pericardial tamponade and other serious consequences. However, LVAD removal using percutaneous approach blockage completely avoids the need for another high-risk surgery, and uses a minimally invasive or even non-invasive approach to help LVAD patients receive treatment.

· Normal life resumed thereafter

· Cardiac function has been completely recovered in several recent follow-ups

Treatment strategies

In order to reduce the risk of LVAD removal surgery, the cardiothoracic surgery team of Fujian Union Medical College Hospital (FUMCH) decided to adopt a new approach by using percutaneous access occlusion, in which the "arterial conduit occlusion umbrella" is sent through the catheter into the artificial conduit of the LVAD to block the blood flow of the conduit to achieve the removal of the LVAD to disable the function of the LVAD, and to truncate the drive line, the severed end of the percutaneous embedded, so as to realize the minimally invasive removal of the LVAD.

The surgery was performed by the team of Cardiac Surgery Professors Chen Liangwan and Dai Xiaofu, and the operation took only 30 minutes. The advantage of this method is that it is less traumatic and less risky, and Mr. Zhang has recovered well after the operation, and his heart is as good as a normal person's without any complication.

Prof. Dai Xiaofu said that this is the first case of LVAD withdrawal utilizing percutaneous access blockade in Fujian Province, and a rare report in China. The procedure reflects the technological innovation and leadership of the cardiac surgery team at Fujian Union Hospital in the field of LVAD, and provides new options and hope for the treatment of patients recovering from heart failure after LVAD implantation.
