Interventional Cardiology Expert Witness
Percutaneous coronary intervention, structural valve work, intracoronary imaging and the procedural complications that follow. The consultants instructed on these cases are practising interventionalists, verified against the GMC specialist register before allocation.
- PCI
- Angiography
- TAVI & structural
- Procedural complications
- STEMI pathway
The cath-lab arm of cardiology.
Most medico-legal work in this subspecialty turns on procedural decision-making: whether the intervention was indicated, whether it was performed to the accepted technical standard, whether the operator should have escalated to surgery or deferred, and whether the complications that followed were foreseeable and managed appropriately.
Accepted UK practice is set by the British Cardiovascular Intervention Society, whose PCI Recommendations are the reference document a report is tested against.
Six areas of practice.
The six areas below cover the medico-legal ground most interventional cases sit within.
-
Percutaneous coronary intervention (PCI)
Coronary stenting, balloon angioplasty and revascularisation decisions in stable disease and acute coronary syndromes — including primary PCI for STEMI under the BCIS recommendations and NICE NG185.
-
Diagnostic coronary angiography
Catheter imaging of the coronary tree — indication, technique, contrast use, vascular access and the interpretation of angiographic findings.
-
Structural heart intervention
TAVI, MitraClip and PASCAL for mitral regurgitation, ASD and PFO closure, and the structural decision-making around valve and septal pathology.
-
Intracoronary imaging & physiology
Intravascular ultrasound, optical coherence tomography, fractional flow reserve and instantaneous wave-free ratio — the adjuncts that inform when and how to intervene on a given lesion.
-
Complex coronary intervention
Chronic total occlusion, left main stem disease, multi-vessel disease and intervention in the high-risk patient, where the procedural calculus is finely balanced.
-
Peri-procedural care & complications
Vascular complications, contrast nephropathy, stent thrombosis, coronary perforation, dissection, and management through the post-procedural period.
Where interventional opinion is instructed.
Interventional cardiology evidence is most often required in clinical negligence work. The subspecialty is also instructed in personal injury, coronial, criminal and regulatory matters where catheter-based decision-making is in dispute.
-
Clinical negligence
Missed indication for PCI in acute coronary syndromes, delayed primary PCI in STEMI, unsupported procedures, and complications attributable to operator decision-making. Tested against NICE NG185 and BCIS standards.
-
Personal injury
Cardiac sequelae of trauma requiring coronary intervention, aggravation of pre-existing coronary disease, and the impact of cardiac procedures on functional capacity for quantum.
-
Inquest & coronial
Peri-procedural mortality, sudden death following recent PCI, deaths in the cath lab, and Article 2 inquests where systemic failures in the primary PCI pathway are alleged.
-
Criminal & regulatory
Causation of death where an unlawful act precipitated a cardiac event, and GMC fitness-to-practise proceedings concerning an interventionalist’s clinical conduct.
Typical reports in this subspecialty.
Five report types cover the bulk of interventional instructions. Each is prepared to the same CPR Part 35 framework.
-
Screening & Merits
Early-stage view on whether the interventional decision-making fell outside accepted practice, and whether the case has prospects worth pursuing.
-
Breach of Duty
Full liability opinion on procedural and pre-procedural decisions — indication, technique, escalation and complication management — tested against BCIS recommendations.
-
Causation
Whether the breach caused or materially contributed to the cardiac outcome, addressing both but-for and material contribution where the medicine permits.
-
Condition & Prognosis
Post-PCI cardiac status, functional capacity, residual ischaemia, stent patency and likely future course — the foundation for the quantum discussion.
-
Critique & Rebuttal
Independent read of an opposing interventionalist’s report — methodology, references, reasoning and conclusions tested before joint discussion or trial.

Four reasons to insist on the subspecialty match.
A general cardiology opinion on an interventional case is rarely enough. Four practical reasons the match matters at the point of instruction.
Active interventional practice.
Each consultant continues to perform PCI and structural cases in current NHS practice. Operator activity is submitted to the BCIS/NICOR national PCI registry, so the data behind the opinion are current rather than recalled.
Current evidence base.
Opinions are referenced to live BCIS recommendations and current NICE NG185 guidance — not how procedures were done a decade ago.
Cath-lab decision-making.
The decisions a case turns on — when to stent, when to defer, when to escalate to surgery, when not to intervene — are assessed by consultants who make them every week.
Subspecialty indemnity.
Each consultant holds medico-legal indemnity covering interventional expert witness work specifically. Indemnity is verified before the instruction is allocated.
