[Acute coronary syndrome with unusual finding of double coronary occlusion, acute and chronic, of the left anterior descending coronary artery].

In patients with acute coronary syndrome, total chronic occlusion of a non-culprit vessel is a frequent angiographic finding (10-30%) and it is associated with increased mortality. The effective treatment of these lesions results in better outcomes, and procedural success depends partly on the anatomical features of the lesion. As indicated by current guidelines, the treatment of non-infarct-related artery lesions is not recommended in the acute setting, even in case of hemodynamic instability.

Persistent redundant Eustachian valve interfering with Amplatzer PFO occluder placement: anatomico-clinical and technical implications.

A 28-year-old man with patent foramen ovale and a prominent Eustachian valve with a history of transient ischemic attack underwent transcatheter closure using Amplatzer patent foramen ovale occluder. During deployment, some of the prominent valve tissue was entrapped on the delivery cable and a piece of the valve was extracted unintentionally. Anatomico-clinical and technical implications are discussed.
