Objective. Coil embolization (CE) for coronary artery perforation (CAP) has not been thoroughly evaluated. This study aimed to evaluate the extent of myocardial damage and impact on cardiac function after CE for CAP. Methods. A total of 110 consecutive patients treated with CE for CAP were retrospectively identified. The degree of myocardial damage and impact on cardiac function were evaluated. Results. Forty-nine (44.5%) cases involved chronic total occlusions. A guidewire was the cause of perforation in 97 (88.2%) patients. The success rate of CE was 98.2%. Almost all patients were prescribed either antiplatelet drugs or anticoagulant medication or both. Patients with perforation types III and IV were found to be prone to creatinine kinase (CK) elevation and epicardial main vessel perforation, thereby causing myocardial damage. No changes were noted in the ejection fraction (EF) in patients with type V distal perforation and collateral channel perforation, while patients with perforation of the epicardial main vessel may show impaired cardiac function afterward. Conclusions. CE is safe and effective for treating CAP, especially when collateral channels and distal vessels are involved. Meanwhile, efforts should be taken to prevent CAP in epicardial main vessels since it may be difficult to treat with CS and cause myocardial damage when bailed out with CE leading to vessel sacrifice. We found that it was not necessary to change the anticoagulant regimen after CE owing to its ability to achieve robust hemostasis.
Introduction: Health care educators are challenged with helping clinicians develop competencies beyond their foundational training. In health care systems where continuing professional development is not integral to practice, clinicians may have few opportunities. We describe the design, implementation, and evaluation of a professional development program in patient safety for Japanese clinical educators to acquire simulation instructional skills and become Patient Safety Champions at their organizations. Methods: Mixed methods were used in a longitudinal pre/post study design. The Kirkpatrick evaluation model was used to evaluate outcomes of a workshop, overall program, on-site training experiences, and impact as Patient Safety Champions. Selfassessment data on skills and knowledge of patient safety, simulation instructional methods, interprofessional collaboration, and leadership were collected and analyzed. Results: Eighty-nine percent of participants facilitated on-site patient safety training within 6 months of workshop completion. Skills and knowledge improvement were observed immediately postworkshop in four categories: patient safety, simulation instructional methods, interprofessional collaboration and communication, and leadership as a patient safety champion. Skills and knowledge increased at 6 months after facilitation of on-site safety training. Program mean satisfaction scores ranged from 84% to 92%. Mean Patient Safety Champion in-facility evaluations were 4.2 to 4.7 on a 5-point scale. Discussion: High levels of knowledge, skill retention, and behavior change are attributed to goal setting, outcome-oriented pedagogy, and reflective sessions. The Patient Safety Champion model and experiential learning approach gave Japanese clinical educators in medicine, nursing, and pharmacy an opportunity to learn from each other in simulations reflecting the practice environment.
