Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European Registry for AAOCA (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres.

EURO AAOCA study database on management for "ANOMALOUS AORTIC ORIGIN OF CORONARY ARTERIES.

This is a simple Excel database in 8 sections (see below). The patient's identification (ID) should be anonymous, and can be decided by each center; the investigators suggest to enclose Centre ID number (which is communicated by the leading center) and a sequential number or date of birth (dd/mm/yy).

If no procedure has been done for the patients , it is required to the "PERIPROCEDURAL, SURGICAL DETAILS" and "POSTPROCEDURAL" data sheets (which are outlined in RED). In the "PERIPROCEDURAL" sheet, the participants may refer either to the surgical or non surgical procedure.

Baseline and long term clinical evaluation sections must be completed for all patients.

In the database, there are lists of multiple different variables which are summarized in tables enclosed in the section, in which each item corresponds to a number.

EURO AAOCA Study DATABASE sections

1. Baseline demo and anatomy: it includes demographic data, and anatomical details for each patient; basic anatomy and course can be selected scrolling an enclosed list; remaining data are requested as yes/no answer
2. Baseline symptoms and indications: it includes symptoms info and indications to surgical/interventional/clinical follow up for each patient; symptoms can be selected scrolling an enclosed list; remaining data are requested as yes/no answer or text; in particular, the participants are required to distinguish between recreational non-competitive sports (2-3/week) and Competitive (>5 times/week), Reason for diagnosis in asymptomatic patient can be selected scrolling a list.
3. Baseline instrumental: it includes all possible diagnostic methodologies used for first diagnosis; the test is considered abnormal when it is gives diagnosis of AAOCA, and in this case , the participants are required to describe the findings as precise as possible. In particular, for non-surgical patients, the participants are required to provide a date of the first time any instrumental test suspected AAOCA. ECG data can be selected scrolling an enclosed list; remaining data are requested as yes/no answer or text
4. Periprocedural: if the patient has gone to surgical or interventional management, the participants are required to fill this section: data can be selected scrolling an enclosed list; remaining data are requested as yes/no answer or text
5. Surgical details: for surgical patients only, the participants are required to fill this section; data can be selected scrolling an enclosed list; remaining data are requested as yes/no answer or text
6. Post procedural: for surgical or interventional patients only, the participants are required to fill this section; data can be selected scrolling an enclosed list; remaining data are requested as yes/no answer or text
7. Follow up 1: this section must be filled for all patients (surgical/interventional /only medical management) and must be updated every year and sent back to the coordinator every June 15th, so as to check yearly the patients. The Investigators suggest an annual follow up for at least 5 years in a row. Follow up data can be selected scrolling an enclosed list; remaining data are requested as yes/no answer or text. T
8. Follow up Instrumental diagnosis: this section must be filled for all patients (surgical/interventional /only medical management) and must be updated every year and sent back to the coordinator every June 15th, so as to check yearly the patients. The investigators suggest to do this for at least 5 years in a row. Follow up data can be selected scrolling an enclosed list; remaining data are requested as yes/no answer or text

Inclusion Criteria:

• All patients with a diagnosis of AAOCA (either referred to surgery or to medical follow-up )

Exclusion Criteria:

• isolated high-coronary take-off (≥ 5mm above sino-tubular junction), anomalous origin of a circumflex from the right coronary artery, anomalous course with a normal origin, and association to major congenital heart disease (i.e. Tetralogy of Fallot, transposition of the great arteries, anomalous origin of a coronary from the pulmonary artery).

all patients undergoing incidental or not diagnosis of AAOCA

The anonymized demographic and clinical data underlying this study can be shared on reasonable request to the principal investigator
