With the development of surgical technology and the need of clinical, transesophageal echocardiography is more and more favored by clinicians. Although the transesophageal echocardiography has developed more than 20 years, yet it has not been widely used in operation at present in domestic. In addition, its application in surgery of children is more rare. It has been confirmed that intraoperative use of transesophageal echocardiography has good safety and wide range of application. We will summarize indications, complications, and the progress of the current technology from the scope of transesophageal echocardiography in pediatric surgery.
Transcatheter aortic valve replacement (TAVR) is an emerging alternative for the treatment of aortic stenosis (AS). Evidence from clinical trials sprang up continuously, and guidelines have listed TAVR as an alternative for part of AS patients. Although old guidelines only recommended TAVR for surgical high-risk or in-operable AS patients, the latest guidelines have expanded its indications enormously. Moreover, there are ongoing TAVR studies on low-risk patients, asymptomatic patients, pure aortic regurgitation patients, bicuspid aortic valve patients,etc. It is believed that the indication of TAVR will continue to expand. More and more patients will benefit from TAVR in the foreseeable future.
