Dental extraction planning can miss the prosthetic valve history that changes prophylaxis. Open this for infective endocarditis decisions: amoxicillin timing, Duke criteria, Enterococcus faecalis bacteraemia, transoesophageal echocardiography and when aortic root abscess or large vegetations need surgical escalation.

Paroxysmal atrial fibrillation is not managed by symptoms alone. Separate episode duration, thromboembolic risk and rhythm-control intent; post-ablation fever, chest pain and dysphagia should prompt contrast CT thorax and urgent surgical input, not endoscopy.

Palpitations, syncope or prolonged QT on ECG should trigger a medication and electrolyte review before inherited disease is assumed. Open this for the Long QT syndrome type 2 trigger history, the limits of negative genetic testing, and why nadolol sits first line once diagnosis is made.

Incidental anomalous coronary anatomy is not managed by discovery alone. This cardiology listen explains why high-risk CT features, exercise-based stress imaging and matched myocardial ischaemia matter, and why a left coronary artery arising from the pulmonary artery changes the referral plan even without symptoms.

This is mainly for cardiology trainees, but the practical point is broader than exam logistics. It makes revision follow the full guideline map rather than current subspecialty comfort, with imaging, angiography, and less familiar topics treated as blind spots to tackle early.

Start here: post-viral chest pain with raised troponin needs a clean sort between myocarditis and pericarditis. The episode makes high-level atrioventricular block a clear escalation point and reminds you that echocardiography is not the final diagnostic test when cardiac magnetic resonance imaging is needed.
