“…By contrast, our percentage plot shows that the length of the AIVA at the inferior ventricular walls is proportionally equal to both sexes. Extremely long AIVAs, as described by Javangula and Kaul (2007) and Varga et al (2020), were not found in our cohort and in the hearts studied by Kalbfleisch andHort (1976) andOzturk et al (2011).…”

“…It was absent in only 14% of hearts studied (Dodge Jr et al, 1988, 1992. In more recent case reports an AIVA that continues as an IIVA in the inferior interventricular groove is considered a rare variant and is termed hyper-or superdominant (Jariwala & Kumar, 2018;Javangula & Kaul, 2007;Shaikh et al, 2018;Varga et al, 2020). In extreme cases, the hyperdominant AIVA runs in the inferior interventricular groove up to the crux of the heart and gives off a left ventricular branch to the inferior surface of the left ventricle (Javangula & Kaul, 2007;Varga et al, 2020).…”

Coronary artery systems of the inferior wall of the ventricles vary considerably.Schlesinger's concept distinguishes dominance of the right or left coronary artery (LCA) or balanced type. LCA dominance has been reported to be associated with increased mortality. Early angiography studies have shown that the anterior interventricular artery (AIVA), a branch of the LCA, often continues on the inferior surface of the heart and may replace the inferior interventricular artery. Others considered an AIVA on the inferior surface of the heart a rare variant. A long AIVA is a strong predictor of death in acute anterior wall myocardial infarction. We determined coronary artery variance at the inferior surface of the ventricles in 134 dissected human hearts and analyzed a possible association between coronary artery variance and age at death. The AIVA extended to the inferior side in 64.9% of the hearts, but rarely reached the basal half of the inferior interventricular groove. Most frequently (53%), it extended into the apical two-fifths of the length of the inferior ventricular walls.An AIVA extending to the apical 40% of the length of the inferior ventricular walls may therefore be considered a common variant. In 20.1% of the hearts, a right inferior diagonal artery was also found. Statistical analysis neither revealed an association between mean AIVA length at the inferior ventricular surface and type of coronary artery dominance nor an association between AIVA length at the inferior ventricular surface or coronary artery dominance type and age at death.

“…The infarction-related artery in inferior STEMI mainly involves the right coronary artery or left circumflex artery. Anatomically, distal occlusion of a dominant LAD, which supplies the posterior descending artery, can also cause inferior STEMI, and that has been reported in previously published cases …”

“…Anatomically, distal occlusion of a dominant LAD, which supplies the posterior descending artery, can also cause inferior STEMI, and that has been reported in previously published cases. 2,3 Mechanical ventilation in the prone position has been recommended as an effective treatment for patients with ARDS. 4 Moreover, especially within the first 30 days after acute chronic obstructive pulmonary disease exacerbations, there is an increased risk of myocardial damage, including STEMI, in patients with prior ischemic heart disease.…”
