Abstract :

<p class="MsoNormal" style="line-height:200%"><span style="font-size:12.0pt;&#10;line-height:200%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Heart receives its arterial supply by coronary arteries that <span style="mso-spacerun:yes">&nbsp;</span>have an epicardial course. Rarely they pass through myocardium forming a myocardial idge that narrows its lumen and decreases the blood flow during systole. Myocardial idges have phylogenic origin and described in lower verteates. Normally right coronary artery passes through atrioventricular groove without bending. Rarely it shows high tortuous bend known as shepherd&rsquo;s crook artery. The present case showed myocardial idges on right coronary artery and its shepherd crook&rsquo;s presentation.Coronary arteries supply the heart during diastole and myocardial idges are significant in conditions of tachycardia which decreases the diastolic period. Shepherd&rsquo;s crook artery will need special attention as it creates disturbances in procedures on right coronary artery.<o:p></o:p></span></p>
