Yan Feifan, along with Liang Zhao Kui, Gu Lin, and the other big shots from the cardiothoracic surgery department—five in total—all streamed into the adjacent training lab.
There they saw Pan Jichuan, Li Tianlin, and Yu Beihua all sitting quietly at their respective workstations, studying thick medical textbooks.
Only Zhu Jian and Berry were still busy.
Yan Feifan was the first to approach Pan Jichuan's workstation. With a gloved hand, he picked up the heart Pan Jichuan had sutured.
The heart muscle is powerful and in a state of perpetual contraction and expansion. Therefore, cardiac suturing has special requirements regarding needle penetration depth, stitch density, and suture tension.
Yan Feifan inspected the suture line, then squeezed the heart firmly a few times to check the integrity of the sutures.
Then, he blew a puff of air into the coronary artery incision to gauge the airflow through the vessel and check the suture line for any leaks.
