Spanish term or phrase: afinarse considerablemente
Se trata del informe de una ecocadiografía de la coronaria izquierda.
El párrafo completo dice lo siguiente:

Arteria de mediano calibre proximal y gran tamaño.
Se bifurca precozmente en un gran ramo diagonal y una rama ocluida 100%.
Luego la DA presenta una lesión del 70% post diagonal y se afina considerablemente.
Sus lechos distales son de buena calidad.

¿Qué quieren decir con "se afina"? y ¿Cual sería su traducción?
De antemano, mil gracias a todos.
