Iraqi Board Thoracic & Cardiovascular Surgery common mistakes
Iraqi Board Thoracic & Cardiovascular Surgery · Understand the traps and how to avoid them.
When a stem gives a hemodynamic picture (e.g., low cardiac output with high filling pressures after cardiac surgery), the candidate picks the answer that matches the named diagnosis in the stem rather than recalculating from the numbers, so they choose a management step that the stated pressures actually contradict.
Under time pressure the label ('tamponade', 'graft failure') anchors attention and the candidate stops reading the measured values, especially when the correct option is a step that must be done before or instead of the labelled intervention.
What to do instead
Before reading the options, write the two or three decisive numbers on scratch paper and state the physiology in one line (e.g., 'equalized pressures + pulsus paradoxus = tamponade physiology'). Then eliminate any option that does not follow from that line, and only afterwards check whether the stem's label is consistent. Practise 20 such stems untimed until the numeric-first habit is automatic.
For a graft or conduit choice, the candidate selects the option based on the patient's age alone (e.g., 'young patient, so mechanical valve') without weighing the stated contraindication, compliance issue, or anatomic constraint, and so misses the option that the specific scenario forces.
Textbook decision rules are memorized as age thresholds, and candidates do not rehearse the exceptions (childbearing plans, anticoagulation adherence, small aortic root, active endocarditis, dialysis) that the exam deliberately places in the stem.
What to do instead
Build a one-page exception table for each prosthesis/conduit decision listing the modifiers that override age: pregnancy intent, bleeding risk, renal failure, root size, endocarditis, life expectancy. For every practice question, name which modifier in the stem changed the answer. Review the table weekly rather than re-reading chapters.
On pulmonary nodule or mediastinal mass items, the candidate jumps to the definitive operation (e.g., lobectomy, resection) and skips the staging or tissue-diagnosis step that must precede it, choosing an option that is correct treatment but wrong sequence.
Candidates study operations in isolation and do not internalize the ordered pathway (imaging characterization, functional assessment, tissue confirmation, staging, then resection), so any plausible operation looks like 'the answer'.
What to do instead
Draw the pathway as a flowchart for each scenario type (solitary pulmonary nodule, anterior mediastinal mass, pleural effusion, oesophageal cancer) and mark the branch points where tissue or staging is mandatory. When answering, ask 'what is the next step?' rather than 'what is the treatment?'. Drill sequence questions specifically, not just treatment questions.
In congenital cardiac questions, the candidate reasons from the adult physiology they know and misassigns shunt direction, mixing status, or ductal dependency, so they choose a management step that would be harmful in that lesion (e.g., giving oxygen or vasodilators where they worsen the circulation).
Congenital lesions are learned as lists of associations rather than as a single shunt-and-resistance model, and the exam tests the physiology in neonates and infants where it differs most from adult practice.
What to do instead
For each core lesion, write a three-line card: anatomy, direction of shunt as pulmonary vascular resistance falls, and what is ductal-dependent. Then state which interventions change pulmonary versus systemic vascular resistance and in which direction. Test yourself by predicting the effect of oxygen, hyperventilation, and vasodilators before checking the answer.
When a vascular stem describes acute limb ischaemia or a ruptured aneurysm, the candidate selects the elegant definitive repair and overlooks the immediate stabilizing manoeuvre or the time-critical first action (heparinization, revascularization urgency, permissive hypotension, immediate transfer) that the stem is actually testing.
Operative technique is over-studied relative to resuscitation and triage, and candidates equate a more complex operation with a better answer.
What to do instead
For each vascular emergency, write the first 30 minutes as a timed checklist (assess viability, anticoagulate, image if time allows, decide open versus endovascular, control blood pressure target). Practise stems by covering the options and stating the first action aloud. Only then compare with the choices.
In perioperative critical care items, the candidate manages a single abnormal number (e.g., a low haemoglobin or a high potassium) instead of the stated clinical context, and chooses transfusion or dialysis thresholds that ignore the patient's stability, bleeding, or cardiac output.
Thresholds are memorized as fixed numbers, while the exam tests context-dependent triggers and the harm of reflexive correction.
What to do instead
For each common ICU problem, record the trigger, the target, and the exception in a three-column table (e.g., transfusion: trigger, target, exceptions in ischaemic heart disease or active bleeding). Answer questions by first classifying the patient as stable or unstable, bleeding or not, then applying the trigger.
On imaging items, the candidate names the modality that best demonstrates a finding rather than the modality that answers the clinical question in that patient, and so chooses MRI where pacemaker status, urgency, or availability makes CT or echocardiography the correct next test.
Radiology is revised as 'best test for X' lists, and contraindications, urgency, and the need for functional information are not linked to the choice.
What to do instead
For each clinical question (rule out dissection, assess valve severity, stage a lung nodule, evaluate a pleural mass), write the first-line test, its limitation, and the alternative when that limitation applies. In practice, state the clinical question in one sentence before selecting the modality.
When a stem includes a complication or near-miss (wrong-site marking, retained swab, mislabelled blood, wrong-side chest drain), the candidate picks the clinical corrective action and omits the reporting, disclosure, or system-level step that the professionalism or patient-safety item is testing.
Candidates prepare clinical content far more than safety and ethics content, and they treat disclosure and incident reporting as optional add-ons rather than mandatory duties with defined pathways.
What to do instead
Learn the local duty-of-candour sequence (recognize, disclose to patient, document, report through the incident system, support staff) and the distinction between individual accountability and system error. Practise by writing the full sequence for five common surgical adverse events.
On evidence-appraisal items, the candidate judges a study by its conclusion or by the prestige of the journal rather than by design, allocation, blinding, effect size with confidence intervals, and applicability to the patient described, and so endorses a claim the methods cannot support.
Critical appraisal is under-rehearsed relative to factual recall, and candidates default to 'randomized means good' without checking conduct, power, or surrogate endpoints.
What to do instead
Use a fixed four-question template on every paper: what was randomized or compared, was allocation and blinding adequate, what is the absolute effect with its interval, and does the population match my patient. Apply it to ten abstracts and write the verdict in two sentences each.
On basic-science items, the candidate answers from operative practice and forgets the underlying anatomy or physiology that the stem isolates (e.g., coronary venous drainage, bronchial versus pulmonary blood supply, lymphatic drainage of the lung, conduction system relations), and picks the clinically familiar but anatomically wrong option.
Applied sciences are studied early and not revisited, and the exam deliberately tests structures that matter in the operating room but are rarely discussed explicitly.
What to do instead
Keep a single annotated diagram set (coronary anatomy and venous drainage, bronchopulmonary segments, mediastinal compartments, conduction system, thoracic duct) and redraw one from memory each week. Link each structure to one operative hazard so the fact becomes retrievable in context.
