The Achilles heel of this procedure has been aortic root dilation and the potential need for a reoperation that may be associated with slightly increased risks in addition to the need for intervention on the pulmonary outflow tract. Modifying the Ross procedure by autograft inclusion inside a Dacron graft seems to have the potential advantage of stabilizing the autograft diameter, which may be associated with improved durability and decrease the need for future intervention. Although the long-term data are satisfactory, the pulmonary homografts are costly and have limited availability, so the need for alternate options for reconstruction of the right ventricular outflow tract exists. Utilization of the autologous pericardium in the reconstruction of neo-pulmonary leaflets may be considered an alternative to other pulmonary valve reconstruction options. We present a few different modifications to the Ross procedure that may have the potential of being more reproducible and more cost effective, especially in areas of the world where homografts and bioprosthetic valves are not readily available.</p>","PeriodicalId":53474,"journal":{"name":"Multimedia manual of cardiothoracic surgery : MMCTS / European Association for Cardio-Thoracic Surgery","volume":"2025 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143034790","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}

Calcified conduit embedded in the sternum or large vessels attached to the sternum presents an especially challenging case. This video tutorial presents a simple safe redo sternotomy technique using an ultrasonic bone scalpel in such high-risk patients. The ultrasonic bone scalpel has a narrow cutting blade that oscillates longitudinally. Because the movements of the blade have a much smaller amplitude and faster speed than those of the usual saw, making a precise cut is possible when holding the ultrasonic bone scalpel onto the bone, and soft tissue can be dissected out with a quick touch. A narrow blade can shave the sternum on the conduit when the layer between the sternum is identified. A lack of understanding of the character of the ultrasonic bone scalpel often limits its potential.

When dealing with patients with complex physiologies and borderline haemodynamics, it is prudent to have a fail-safe method of approaching decannulation from extracorporeal membrane oxygenation. Standardizing the extracorporeal membrane oxygenation weaning strategy with a pump-controlled retrograde trial off protocol seems a feasible alternative to traditional venoarterial extracorporeal membrane oxygenation weaning approaches. We advocate that having a pump-controlled retrograde trial off protocol for weaning could be done consistently, reliably and validly to assess a patient's ability to be weaned off extracorporeal membrane oxygenation successfully. The advantages of a pump-controlled retrograde trial off versus traditional weaning strategies are threefold: (i) It allows one to do a stress test on the cardiorespiratory reserve of the patient with borderline haemodynamics while having the extracorporeal membrane oxygenation circuit as a fail-safe protection. (ii) It can be standardized and consistently performed regardless of the operator. (3) It allows multiple attempts at weaning without sacrificing the extracorporeal membrane oxygenation circuit by a reduction in risk of circuit clotting. We present the step-by-step approach for conducting a pump-controlled retrograde trial off protocol with video in a neonate with myocarditis, with improving but borderline myocardial function and moderate to severe mitral regurgitation. The pump-controlled retrograde trial off was able to predict successful separation from extracorporeal membrane oxygenation, and the patient was subsequently decannulated successfully.</p>","PeriodicalId":53474,"journal":{"name":"Multimedia manual of cardiothoracic surgery : MMCTS / European Association for Cardio-Thoracic Surgery","volume":"2025 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142980748","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}
