The chance finding at multislice computed tomography coronary angiography of an ectopic origin of the left circumflex coronary artery from the right sinus of Valsalva

Anomalous origin of the left circumflex artery from right sinus of Valsalva: a rare case but with great clinical relevance

“…Among them, only those with an interarterial course are regarded as hidden conditions at risk of myocardial ischemia and sudden cardiac death (SCD). [1][2][3][4][5][6][7][8] We report an uncommon case of anomalous origin of LCx from the right sinus of Valsalva and a retroaortic path causing myocardial ischemia.…”

Atypical presentation of Takotsubo syndrome early after pacemaker implantation

“…This condition mimics an acute myocardial infarction (AMI) because of the symptoms and the new onset of ST segment elevation and/or negative T waves, but without fi ndings of acute obstructive coronary artery disease at angiography, although these can be present in 10-29% of cases. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] The diagnosis is made with invasive coronary angiography and ventriculography, together with transthoracic echocardiography which can show different patterns: typical "apical ballooning" of the left ventricle (LV), characterized by apical akinesis and hyperkinesis of the basal segments, or atypical patterns, including the midventricular, basal, and focal wall motion patterns, all of these with reduced ejection fraction. 20 The exact mechani- sm of TTS is unknown, but it is hypothesized that a sudden massive surge of circulatory catecholamines (adrenaline, noradrenaline) from a physical or emotional stress may play a central role.…”

Long-term complication of the thoracic radiation in breast cancer: An complete atrioventricular block case

“…Among the belated complication of radiation therapy may include coronary heart disease, pericardial and myocardial disease, injury to cardiac valves, conduction system abnormalities, and other disease conditions [4][5][6][7][8].…”
