Background: Guidelines endorse coronary artery bypass as the preferred revascularization strategy for patients with left main and/or multivessel coronary artery disease (CAD). However, many patients are deemed excessively high risk for surgery after Heart Team evaluation. No prospective studies have examined contemporary treatment patterns, rationale for surgical decision-making, completeness of revascularization with percutaneous coronary intervention (PCI), and outcomes in this high-risk population with advanced CAD.

Article Synopsis
  • The study aimed to compare the in-hospital and long-term outcomes of retrograde versus antegrade-only percutaneous coronary intervention (PCI) for treating chronic total occlusion (CTO).
  • A total of 885 CTO procedures were analyzed, showing retrograde procedures had more complex lesions and lower technical success, leading to higher in-hospital major adverse cardiac and cerebrovascular events (MACCE).
  • Although the retrograde group had worse outcomes during the hospital stay, the 1-year outcomes were similar to the antegrade-only group, indicating potential improvements in long-term results.

Introduction: Anorectal melanoma (ARM) is a rare disease with a poor prognosis. There is no consensus as to the optimal primary surgical treatment for ARM, with advocates for both radical (abdominoperineal resection [APR]) and conservative strategies (wide local excision [WLE]). Here, we report a systematic review of studies comparing outcomes between these strategies.

Ano-uro-genital (AUG) mucosal melanomas are rare cancers associated with poor outcomes and limited evidence-based management. The United Kingdom AUG mucosal melanoma guideline development group used an evidence-based systematic approach to make recommendations regarding the diagnosis, treatment and surveillance of patients diagnosed with AUG mucosal melanomas. The guidelines were sent for international peer review, and are accredited by The National Institute for Health and Clinical Excellence (NICE).

Background Prior research has shown that providers may infrequently adjust antianginal medications (AAMs) following chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Patient characteristics associated with AAM titration and the variation in postprocedure AAM management after CTO PCI across hospitals have not been reported. We sought to determine the frequency and potential correlates of AAM escalation and de-escalation after CTO PCI.

Article Synopsis
  • A study investigated how chronic total occlusion (CTO) percutaneous coronary intervention (PCI) affects patients with refractory angina, focusing on their quality of life before and after the procedure.
  • Out of 1000 patients, 148 had refractory angina, and while the technical success rate for the procedure was about 81%, those who had successful surgeries saw significant improvements in their symptoms and overall health status after one year.
  • The findings suggest that refractory angina is common among these patients, and successful CTO PCI leads to large, lasting improvements in health-related quality of life measures.
