“…10 These anomalies are mostly asymptomatic, however, clinical presentation in adults may result from myocardial ischaemia manifesting as angina, syncope, arrhythmias and even sudden death. 11,12 In our study, we found a communicating branch of the anterior interventricular artery was anastomosed with RCA on the anterior aspect of infundibulum. This arteria anastomotica infundibularis magna is a very rare incidence found during our study and a detailed literature survey showed it is not reported elsewhere.…”

BACKGROUND Knowledge of coronary artery branching pattern and their anomalies that occur during foetal development is essential for clinicians. They are associated with high incidence of morbidity and mortality due to congenital heart diseases. Failure to recognise them can lead to inadequate or prolonged procedures and may also lead to misdiagnosis and complications such as accidental ligation. MATERIALS AND METHODS A properly embalmed and stored 50 human heart specimens were dissected in the age group of 20-65 years to study the course and distribution of coronary arteries. The study was conducted in dissection hall,

“…No está claro el mecanismo fisiopatológico por el cual se produce la isquemia; existen diversas hipótesis para explicarla, entre ellas la compresión entre la aorta y la pulmonar por aumento de presión en ambos vasos durante el ejercicio; la deformación del ostium de la arteria, su orientación tangencial desde el origen y la presencia de cordones fibrosos proximales; sin embargo, la teoría más aceptada en la actualidad es la disposición intramural de la arteria en la capa media de la aorta. Si el trayecto es intramural en la aorta se produce obstrucción de la coronaria durante períodos de hipertensión arterial o por espasmo coronario (25,26).…”

El dolor torácico no relacionado con trauma es una causa importante de consulta en los servicios de urgencias, con frecuencia alrededor del 10 %, y es secundario al síndrome coronario agudo. La mayoría de las veces está relacionado con la formación de un trombo por ulceración o ruptura de una placa aterosclerótica. En algunos casos es secundario a causas raras como las anomalías del origen de las arterias coronarias. Presentamos el caso de un paciente con origen anómalo del tronco de la arteria coronaria izquierda, que ingresó con cuadro clínico sugestivo de síndrome coronario agudo sin elevación del segmento ST. Se discuten sus principales aspectos, el significado clínico y las opciones terapéuticas.

“…Of the detected CAAs, 87% were origin and distribution anomalies, 13% were fistulas, and 0.1% were anomalies of the right coronary artery (RCA) originating from the left sinus of Valsalva 1) . Another study reported that during cardiac computed tomography (CT) of 360 consecutive patients, CAAs were detected in 2.69% of cases 2) . Thus, occurrence of CAAs is uncommon, and the prevalence of single coronary arteries is as low as 0.008-0.067% 3) .…”
