Radiation-Associated Calcific Right Coronary Artery Occlusion Presenting as ST-Elevation Myocardial Infarction: Emphasizing the Need for Early Cardiovascular Screening

Figures

  Figure 1. Sinus rhythm with second-degree Mobitz 1 (blue lines) and 2 (red circles), with ST elevations in lead II, III, and avF (red arrows) and reciprocal ST segment depression and T wave inversion involving lead I, avL, V4, V5, and V6 (blue arrows).

  Figure 2. Left circulation: patent LAD artery and LCx with collateral and calcium deposits. LAD, left anterior descending; LCx, left circumflex artery

• 

  Figure 3. Right circulation shows a 99% stenotic lesion involving the ostia and proximal part of the RCA and another 80% stenotic lesion in the mid-RCA. RCA, right coronary artery

  Figure 4. ECG shows sinus rhythm (red circles) with a heart rate of 75 beats per minute and reversing ST and T wave changes (red and blue arrows) that were previously shown in the initial ECG.
