Objective To compare the efficacy of additional tricuspid valve annuloplasty (TVP) and isolated closure for atrial septal defect (ASD) with moderate to severe tricuspid regurgitation (TR). Methods Clinical data of the patients diagnosed with ASD combined with secondary moderate to severe TR and treated in our hospital from January 2009 to June 2020 were retrospectively analyzed. Patients were divided into a TVP group and a non-TVP group based on whether TVP was performed simultaneously. The baseline data of two groups were matched with a ratio of 1∶1 propensity score. Results A total of 32 pairs from 257 patients were successfully matched. In the TVP group, there were 24 females and 8 males with an average age of 44.0±13.1 years. In the non-TVP group, there were 28 females and 4 males with an average age of 44.5±11.6 years. The TR area and estimated pulmonary artery pressure in the two groups were significantly decreased compared with preoperation (all P<0.001). The TR area (P=0.001) and the estimated pulmonary artery pressure (P=0.002) were decreased more significantly in the TVP group than those in the non-TVP group. Linear regression analysis showed that age and preoperative TR area had a positive correlation with TR area at follow-up (β=0.045 and 0.259, respectively, both P<0.05), while additional TVP had a negative correlation (β=–1.542, P=0.001). Conclusion Additional TVP can significantly reduce the TR area and pulmonary artery pressure, and elderly patients with severe TR before surgery should actively receive TVP.

AIM: To describe the application of image acquisition function of smart phone with slit lamp examination in the ophthalmology residency training program.

METHODS: The supporting set for smart phone can be securely connected to the ocular lens of slit lamp microscopy. The anterior or fundus photos and dynamic videos were obtained through slit lamp examination with non-contact lens, three-mirror lens or gonio lens. Acquired images or recorded videos were transmitted to ophthalmology trainee by using wireless local area network(WLAN), WeChat and other software.

RESULTS: High quality images and dynamic video could be successfully taken with smart phone and supporting set by slit lamp examination, which could clearly display tissue details and pathological features. The fast transmission of image data can enable more trainees to access clinic education resource simultaneously and communicate with each other timely and effectively.

CONCLUSION: High resolution smart phones are wildly used and supporting sets are very accessible; thus high quality of images could be easily obtained for clinical teaching purpose. Furthermore, it enriches the clinical teaching resources. So the application of image acquisition function of smart phone with slit lamp examination is worthy in the standardized training of ophthalmology residents.
