Pectus excavatum
“Funnel chest” — the breastbone dips inwards
Looks like: a central hollow in the chest, from a shallow dish to a deep crater; often asymmetric, often deeper on the right.
Feels like: breathlessness and early fatigue on exertion, palpitations, occasional chest ache — or nothing physical at all.
The pattern: present from childhood, typically deepening sharply through the adolescent growth spurt.
Inside the chest: in deeper defects the sternum pushes the heart to the left and compresses it — the reason “I’ve just never been sporty” is so often the presenting complaint.
