Week 7 - Hannah Sheffield

 This week, I had the opportunity to shadow Dr. Girardi's, cardiothoracic surgeon, Aortic Valve Repair procedure. This was an open heart surgery where the patient's heart would stop, so that the clinician can replace the diseased aortic valve with an artificial valve along with a graft. When the patient's heart is stopped, the perfusionist work with the Heart-Lung machine to ensure that circulation is maintained through the rest of the organs. The surgery required a lot of precise suturing technique to ensure that the artificial valve stays in place. Afterwards, the patient's heart starts back up to ensure that there is adequate circulation. 

As for research, I was able to make a lot of progress in optimizing the delay. I needed to switch to a different method, called Grid Search, where the model is given several timepoints, and it needs to guess which timepoint provides an optimized delay. We made a lot of headway in the code, and this weekend, I will be bulk running the cases. Looking forward to presenting the on-going work that is occurring in the lab.

Week 3: Eddie Wei - Multimodal Endoscope

Figure 2: Current OCT-Red ( Freund et al.)  and Confocal Fluorescence Microscopy-Green ( Wang et al. ) images in comparison to Histology.           As a brief review of their demonstrated applications in urology, OCT uses backscattered near-infrared light to generate depth-resolved structural images and can delineate bladder layers up to the muscularis with limited cellular information [1], while confocal fluorescence endoscopy uses fluorescein-induced emission and optical sectioning to distinguish...

Week One: Eddie Wei

Over the first week of immersion, I had the opportunity to observe a couple standard urologic operating room procedures, each offering a different perspective on diagnosis, imaging, and operative care. On June 1, I observed two standard operating room procedures. The first involved the treatment of four urinary bladder stones using a cystoscope inserted through the male urethra. The cystoscope was first equipped with a specialized head capable of generating a stream of water to break down the stones. After fragmentation, the water head was replaced with a suction tube to remove the stone fragments and excessive water from the water jet. The procedure was performed under direct real time visualization with a  standard 3x magnification camera integrated into the cystoscope. This procedure lasted 2-3 hours, with 2 and a half hours allocated to breaking down these stones using the water jet.  The second procedure involved a female patient undergoing blue-light cystoscopy to evalua...

Week 1- iqra

This week started off pretty slow since I didn’t meet with my clinician until Wednesday, but things picked up quick ly after that. One thing that has made a big difference is that Dr. Cheung sent an email out to the department about me shadowing, which has allowed me to move around and observe a variety of electrophysiology procedures rather than being limited to a single physician or case type. This has given me exposure to many different aspects of the field and has helped me gain a broader understanding of cardiac electrophysiology. In addition to clinical observations, I also met with one of the medical students working on my research project. During our meeting, we discussed some of the technical details and logistics of the project and worked through a few questions regarding the overall direction of the research. We are still in the early stages of planning, so there are additional details that need to be worked out, and we plan to continue those discussions next week. On Wednes...
