Overview

• The Cheshire Coroner’s Court concluded in August 2025 that Carla Marie Longshaw’s death resulted from sudden cardiac arrest linked to a congenital double ostium in her right coronary artery.
• Assistant Coroner Elizabeth Wheeler determined there were no deficiencies in Longshaw’s prior treatment for low potassium at Macclesfield Hospital.
• Consultant acute physician Dr. Sanjeev Srivastava explained that right coronary artery double ostium is typically benign and cannot be detected without invasive procedures.
• Longshaw, a 39-year-old scientist from Sandyford, Stoke-on-Trent, collapsed on December 23, 2024, at Luis Muñoz Marín International Airport while flying to Puerto Rico for Christmas.
• The inquest highlights the challenge of diagnosing hidden congenital heart defects before a catastrophic event and provides legal closure for her family.
