Aspectos anatómicos y biométricos de los puentes de miocardio y sus relaciones con la arteria interventricular anterior y venas adyacentes.

Myocardial bridge and coronary arteries: morphological study and clinical significance

“…These findings were in accordance with the results stated in literature [5,12,26,28]. According to the results of previous literature, the second common location of the MB was the diagonal branches of AIA and PIA branch of RCA (13.8%, each) [5].…”

“…Moreover, a significance discrepancy was reported between cadaveric and angiographic studies regarding the incidence, frequency and prevalence of MB, where in cadaveric studies, the range of MB incidence was 5-86%, while in the angiographic studies, the occurrence of MB ranged from 0.5% to 33% [4,19,26]. The difference in the incidence and frequency of MB was supposed in part to be attributed to the sample size, morphological characters of MB, method of research, gender and ethnicity of the population selected [26].…”

“…MB are commonly seen on the left coronary artery (LCA) trunk and/or on one of its branches, especially on the anterior interventricular artery (AIA), which represents 12-63% of MB, its lateral branch (13%) and its circumflex artery (2.8-6.7%). Also, they are observed on the diagonal artery (DA), marginal arteries, posterior interventricular artery (PIA) and right coronary artery (RCA) [26].…”

Descripción angiográfica de los aspectos anatómicos y clínicos de la arteria interventricular anterior en un grupo de personas colombianas

“…En Brasil, Sousa et al . disecaron la arteria interventricular anterior de 30 corazones humanos y reportaron puentes miocárdicos en el 46,7 %, los cuales afectaban principalmente a los segmentos 13 y 12 17 .…”

Descrição morfológica e implicações clínicas de pontes miocárdicas: um estudo anatômico em colombianos

“…MB generally originate in the left coronary artery (LCA) trunk and branches, especially in the anterior interventricular artery (AIA) (12%-63%), circumflex artery (CA) (2.8%-6.7%) and its lateral branch (13%). They are also found in diagonal arteries (DA), marginal arteries (MA) and coronary veins 13,14 . This research was aimed at determining MB incidence in the half-caste Colombian population and establishing…”
