While animal and mock-circuit models have historically been the main arena to test new operative techniques and concepts, the recognition that complex cardiovascular anatomy and circulation can be modeled mathematically ushered a new era of collaboration between surgeons and engineers. In 1996, the computational age in congenital heart surgery began when investigators in London and Milan tapped the power of the computer to simulate the Fontan procedure and introduced operative improvements. Since then, computational modeling has led to numerous contributions in congenial heart surgery as continuing sophistication and advances in numerical and imaging methods furthered the ability to refine anatomic and physiologic details. Idealized generic models have given way to precise patient-specific simulations of the 3-dimensional anatomy, reconstructed circulation, affected hemodynamics, and altered physiology. Tools to perform virtual surgery, and predict flow dynamic and circulatory results, have been developed for some of the most complex defects, such as those requiring single ventricle palliation. In today's quest for personalized medicine and precision care, computational modeling's role to assist surgical planning in complex congenital heart surgery will continue to grow and evolve. With ever closer collaboration between surgeons and engineers, and clear understanding of modeling limitations, computational simulations can be a valuable adjunct to support preoperative surgical decision making.</div>","PeriodicalId":38774,"journal":{"name":"Pediatric Cardiac Surgery Annual","volume":"23 ","pages":"Pages 2-10"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1053/j.pcsu.2020.01.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37889476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Airway compression and/or cartilage malformation is a fixed or static narrowing of the airway typically caused by great vessel malposition and/or abnormalities and may also contribute to airway narrowing. Although imprecise and misleading, the term TBM is often used to represent both problems, static and dynamic airway narrowing, which only serves to confuse and may mislead the treatment team into ineffective therapies.The consequences of airway narrowing caused by dynamic TBM and/or static compression includes a range of clinical signs and symptoms, depending on the location, extent, and severity of the airway collapse. All patients with mild to severe TBM benefit from medical management to optimize airway clearance of mucus. The milder cases of TBM may become asymptomatic with this therapy, allowing time for the child to grow and the airway to enlarge without the consequences of recurrent infections.

Lower recovery rate may be a reflection of sicker preoperative status, and thereby a more advanced stage of heart failure (preoperative intubation: >2/3 in the United States vs <1/3 in Germany).

Typically, major epicardial coronary arteries are easily identified during first-time operations. However, in reoperative surgery, epicardial adhesions can obscure coronary vessels making their identification challenging. This paper describes the application of intraoperative fluorescence imaging in congenital heart surgery to obtain real-time coronary artery visualization for operative planning in order to avoid coronary injury. The fluorescence imaging utilizes indocyanine green (ICG). ICG is diluted to 0.28 mg/mL, and 0.1–1.0 mL of ICG solution is delivered via the cardioplegia cannula into the coronaries. A handheld imaging probe illuminates the field with near-infrared laser light, which excites ICG fluorescence. The fluorescence is captured by a camera, and the signal is transmitted to a monitor for real-time viewing. The imaging probe shows the precise coronary anatomy, enabling identification of the optimal ventriculotomy site. Intraoperative fluorescence imaging is a safe and effective technique for characterizing coronary anatomy. This technique enhances procedural planning and helps minimize the risk of coronary injury during reoperative congenital heart surgery.</div>","PeriodicalId":38774,"journal":{"name":"Pediatric Cardiac Surgery Annual","volume":"23 ","pages":"Pages 11-16"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1053/j.pcsu.2020.02.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37889471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
