The text of an expert technique submission should provide sufficient detail to permit an experienced surgeon to follow the proposed guidelines, while including no extraneous background material. Please write to the level of the practicing cardiothoracic surgeon. Special headings are recommended to standardize the presentation and to ensure that specific points are addressed in each description. For most headings, a single paragraph or a number of bullet points should suffice. Headings to use include:
- Patient selection. A brief paragraph describing which patients are particularly good candidates for the procedure. When appropriate, specific exclusion criteria should be listed.
- Operative steps. List as completely as possible the unique operative steps that are required to successfully perform the procedure.
- Preference card. List any unusual instrumentation, specific suture material, instructions for the allied health staff, etc.
- Tips and pitfalls. This section involves perhaps the most personal expression of the author and is often the most useful to the reader. Tricks of the trade and potential challenges to be aware of are very important. Describe what you look for that determines whether things are going well, or whether the procedure should be altered or aborted.
- References or Suggested Reading. A short list (5-10) of recently published and important articles should be provided and cited/listed as described below in the references section. Please be sure to include appropriate articles from your own bibliography. Please reference other LACES published articles/videos, if appropriate and pertinent.

Expert technique submissions should typically include no more than five video clips and eight images.
