Common Pitfalls in cardiology negligence claims.
The recurring patterns that derail cardiology negligence claims — missed diagnoses, inadequate records review, subspecialty mismatch in the expert evidence, and the CPR Part 35 procedural traps the panel sees most often.

The diagnoses most commonly missed in cardiology negligence claims.
A small number of cardiac diagnoses account for a substantial proportion of cardiology negligence claims. Each is missed for predictable clinical reasons; recognising the pattern is the first step in scoping the evidence the report must address.
High-risk missed diagnoses
- Acute coronary syndrome Missed or misattributed to anxiety or reflux, particularly in women and younger patients presenting with atypical symptoms.
- Aortic dissection Misread as MI because presenting symptoms and initial cardiac markers overlap; CT aorta not requested in time.
- Infective endocarditis Overlooked as flu or sepsis, especially in patients without known valvular disease; blood cultures and echo not obtained.
- Heart failure Attributed to COPD, deconditioning or obesity; BNP and echo not requested at first presentation.
Why these diagnoses are missed
- Atypical presentation Women, younger patients and those with diabetes commonly present without the classical chest pain pattern.
- Presentation overlap Aortic dissection, MI and pulmonary embolism share early symptoms; the diagnostic differentiator is imaging or D-dimer, not history alone.
- Single-snapshot diagnostics A single ECG or single troponin may be normal early; serial testing is the safety net and is often the omission point.
- Discharge pressures Crowded ED conditions can drive premature discharge before serial testing or imaging is completed.
How subspecialty mismatch undermines cardiology claims.
Instructing a general cardiologist for an electrophysiology question, or an interventional cardiologist for a heart failure question, leaves the opinion vulnerable at trial. The expert’s duty under CPR 35.3 is to assist the court within their expertise — not beyond it.
Common expert errors
- Opining beyond subspecialty experience — for example, an electrophysiologist commenting on valve surgery outcomes.
- Failing to address causation separately from breach of duty, conflating the two in a single opinion.
- Drifting from impartial opinion towards advocacy for the instructing party.
- Not referencing the ESC or NICE guidance that applied at the relevant time.
How mismatch surfaces at trial
The defendant’s barrister will probe the expert’s substantive clinical practice in the specific area in question, the recency of the expert’s relevant NHS work, and whether the expert is on the GMC specialist register for the relevant sub-area. Opinions outside the expert’s day-to-day clinical practice become harder to defend under cross-examination, and the report’s weight with the court is reduced.
Subspecialty hubsRecords-review omissions that weaken the claim.
Serial ECGs, troponin trends and pre-hospital ambulance records are commonly missing from the bundle when the instruction reaches the panel. The omissions tend to weaken breach and causation arguments before the expert has even opened the records.
Critical omissions
- Serial ECGs Initial and repeat ECGs not collected or not compared in acute coronary syndrome cases; dynamic changes missed.
- Troponin trends Single troponin reading reviewed in isolation; the rise-and-fall pattern that defines NSTEMI not shown.
- Echocardiogram reports Ejection fraction, regional wall motion abnormalities or valve findings not extracted from the imaging report.
- Pre-hospital records Ambulance ECGs and paramedic clinical impressions not requested; the timeline starts at A&E rather than at first contact.
A typical failure pattern
A typical pattern: a claimant with unstable angina is discharged from ED after a single normal ECG and a single normal troponin. Serial ECGs taken hours later on a return visit reveal dynamic ST-segment changes that would have prompted earlier admission and intervention. Without the initial-versus-serial comparison documented in the bundle, the breach argument is harder to evidence even where the underlying clinical failure is clear.
Missed MI condition pageLimitation and procedure across the UK.
Limitation periods, expert evidence rules and pre-action protocols differ across the four UK nations. The cardiology opinion is unchanged across jurisdictions; the procedural wrapper differs.
England and Wales
Three-year limitation under section 11 of the Limitation Act 1980. CPR Part 35 and Practice Direction 35 govern expert evidence, with the expert’s primary duty owed to the court.
Scotland
Three-year limitation under section 17 of the Prescription and Limitation (Scotland) Act 1973. Expert evidence sits under the Civil Evidence (Scotland) Act 1988 and the Rules of the Court of Session or Sheriff Court Rules; procedure differs materially from CPR Part 35.
Northern Ireland
Three-year limitation under Article 7 of the Limitation (Northern Ireland) Order 1989. Pre-action protocol for clinical negligence differs from England and Wales; the expert evidence framework otherwise closely tracks the CPR Part 35 model.
CPR 35.6 questions: what is and is not permitted.
Under CPR 35.6 the opposing party may put written questions to the expert within 28 days of service of the report. Questions must seek clarification, not new analysis or cross-examination by post. Inappropriate questions can be objected to, refused or referred to the court for directions.
Permissible questions
Questions properly within the scope of CPR 35.6:
- Clarification of an ambiguous term or sentence in the report.
- A request for additional reasoning where an opinion is stated without supporting analysis.
- A query about whether the expert considered a specific clinical guideline or piece of evidence that was in the bundle.
Outside the scope of CPR 35.6
Questions outside the scope of CPR 35.6 that the expert may refuse to answer or refer to the court:
- Demands that the expert carry out new analysis on material not previously provided.
- Requests for opinion on hypothetical scenarios outside the original instruction.
- Cross-examination-style questions framed to challenge the expert’s independence rather than seek clarification.
- Questions that significantly expand the scope of the report rather than clarify what is in it.
What a CPR Part 35 cardiology report must contain.
Reports that fall short on independence, balance or causation analysis are vulnerable at trial. The panel builds reports that meet CPR Part 35 and Practice Direction 35 requirements from the outset.
-
Structural elements Issue, materials reviewed, reasoning, conclusions, declaration of truth – numbered paragraphs, sources cross-referenced.
-
Common deficiencies Lack of subspecialty focus, breach and causation conflated, no reference to the ESC or NICE guidance applicable at the relevant time.
-
Internal quality control Drafts are reviewed internally for procedural compliance and consistency with the instruction before delivery to the instructing solicitor.
-
Pre-delivery check Declaration of truth, sources of information, expert’s subspecialty position and GMC details all confirmed before the report leaves the panel.
Common questions on cardiology negligence pitfalls.
-
What are the most common cardiology negligence pitfalls? Missed diagnoses (aortic dissection, infective endocarditis, atypical ACS), inadequate records review (serial ECGs, troponin trends, pre-hospital records), subspecialty mismatch in the expert evidence, and CPR 35 procedural traps.
-
How are subspecialty mistakes in expert evidence avoided? Match the expert to the clinical question – interventional, electrophysiology, imaging, heart failure, valve and structural, congenital, inherited cardiac conditions, general and acute cardiology. Verify the GMC specialist register entry and recent NHS clinical practice in the specific area.
-
Which records are most often overlooked? Pre-hospital ambulance ECGs and paramedic clinical impressions, serial troponin measurements, echocardiogram reports (ejection fraction, regional wall motion abnormalities, valvular findings), and angiogram images alongside procedural notes.
-
How do limitation periods differ across UK jurisdictions? Three years in each of the four nations – Limitation Act 1980 (England and Wales), Prescription and Limitation (Scotland) Act 1973 (Scotland), Limitation (Northern Ireland) Order 1989 (Northern Ireland) – but pre-action protocols and procedural rules around expert evidence differ.
