Hypoxic brain injury secondary to haemopericardium and tamponade complicating ruptured right coronary artery during coronary angioplasty
AI-generated summary
Mr Trevor McDonald, 43-year-old male, died from hypoxic brain injury following cardiac tamponade complicating coronary angioplasty. During elective PCI at Frankston Hospital, he sustained right coronary artery perforation causing pericardial bleeding and tamponade. Following initial pericardiocentesis, he likely suffered laceration of the right ventricular outflow tract (RVOT), possibly from the drainage needle inserted without ultrasound guidance. Despite resuscitation and emergency transfer to a tertiary cardiac centre, he suffered irreversible hypoxic brain injury. Key clinical lessons: (1) complications of PCI in regional facilities without on-site cardiac surgery incur significant time delays for definitive surgical management; (2) emergency pericardiocentesis carries risk of vessel injury, particularly when performed without imaging guidance; (3) prolonged cardiac tamponade causes incremental cerebral hypoxia; (4) all interventional cardiologists should maintain expertise in emergency tamponade management and have cross-accreditation with cardiac surgical centres; (5) robust inter-hospital transfer protocols are essential.

Coroner's recommendations
Peninsula Health should ensure the Director of Frankston Hospital PCI Unit is an experienced interventional cardiologist who is cross-accredited to at least one tertiary cardiothoracic unit and practices interventional cardiology at Frankston
Department of Health request the Intensive Care Advisory Committee to consider access to intensive care beds for emergency cardiac surgical patients in the context of overall intensive care bed supply in the State
Department of Health seek advice from the Cardiac Clinical Network to integrate its role in emergency transfer of patients from stand-alone regional PCI units with services of the Intensive Care Advisory Committee and Adult Retrieval Victoria
Cardiac Society of Australia and New Zealand consult with Department of Health and Cardiac Clinical Network to ensure guidelines for stand-alone regional PCI units account for local arrangements that reduce time for emergency transfer to tertiary cardiothoracic units
Cardiac Society of Australia and New Zealand reconsider advice about transfer time from stand-alone regional PCI units to include time required to locate a bed in a receiving hospital and time for emergency transfer
Cardiac Society of Australia and New Zealand review guidelines to require all interventional cardiologists performing angioplasties in regional stand-alone PCI Suites to be cross-credentialled to tertiary high-volume cardiothoracic units and work in such units for sufficient time to maintain exposure to emergency responses
