Pre-participation sports evaluation — branching viva

Branching framework

Open with the one-sentence framing and the goal of the evaluation. The pre-participation sports evaluation screens a child or adolescent before sport to detect the conditions that threaten life or limb and to promote safe participation, and the fellowship task is to take the AHA 14-element cardiovascular history, to recognise the red-flag items, and to classify the clearance. State the three-part framing — the screen detects the threat, the clearance promotes safe participation, and the emergency action plan protects when the screen misses — before you discuss any single athlete. [1] [3]

Reproduce the AHA 14-element screen and its 7-3-4 split. The fourteen elements divide into seven personal history items, three family history items, and four physical examination items. The seven personal items are exertional chest pain, unexplained syncope or near-syncope, excessive dyspnea or fatigue with exercise, a prior heart murmur, an elevated blood pressure, a prior restriction from sport, and prior cardiac testing. The three family items are a sudden death before fifty, disability from heart disease in a close relative under fifty, and a known familial cardiomyopathy or channelopathy. The four examination items are the murmur supine and standing, the femoral pulses, the stigmata of Marfan syndrome, and the brachial blood pressure. [1]

Branch to the exertional syncope red flag and the first athlete. A blackout during a sprint is exertional syncope, and exertional syncope is sudden cardiac death until proven otherwise. Combined with the paternal uncle's sudden death at forty-one, this athlete has two positive elements and is restricted from sport pending an electrocardiogram, an echocardiogram and a cardiology opinion. State that clearing him as dehydrated and reviewing later is the error that costs the life, because the next exertional event may be the fatal one. [3]

Branch to the standing murmur examination and hypertrophic cardiomyopathy. The murmur of hypertrophic cardiomyopathy is dynamic — it intensifies on standing or with the Valsalva manoeuvre, while the innocent flow murmur softens or disappears. State that you listen to every athlete supine and standing before you clear the heart, because auscultating only supine misses the distinction that separates the benign flow murmur from the lethal obstructive one. [1]

Branch to the history-versus-ECG controversy. The AHA concludes that the history-and-examination screen is the minimum standard but that its sensitivity is too low and a mandatory electrocardiogram is not justified across the United States because of the cost and the false-positive rate. The European Society of Cardiology, citing the Italian experience and the Corrado study, endorses the electrocardiogram where the interpreter expertise exists. State that the AMSSM 2017 position statement frames the choice as a shared, evidence-informed decision, and be ready for the probe on the athlete's heart versus cardiomyopathy distinction that the electrocardiogram raises. [4] [3]

Branch to the blood pressure staging and the second athlete. A blood pressure of 132 over 84 in a sixteen-year-old sits in the stage 1 range of the AAP clinical practice guideline, which defines elevated blood pressure as 120 up to 130 for the systolic with a diastolic under 80, stage 1 as 130 up to 140 over 80 up to 90, and stage 2 as 140 or more over 90 or more for those aged thirteen and over. State that a single elevated reading is repeated and confirmed on three separate occasions, and that the clearance is conditional on the confirmed staging and the control. [7]

Close with the clearance decision and the emergency action plan. The clearance falls into cleared without restriction, cleared with conditions, and restricted pending evaluation, and the first athlete is restricted while the second is conditionally cleared pending the blood pressure confirmation. State that the written emergency action plan with access to a defibrillator within minutes is the protection that catches the athlete the screen misses, because survival from exertional sudden cardiac arrest falls by about ten per cent for every minute the defibrillation is delayed. The examiner rewards the candidate who frames the evaluation around the screen, the clearance, and the protection. [3] [4]
