CARDIOVASCULAR JOURNAL OF AFRICA • Volume 33, No 4, July/August 2022 AFRICA 221 Fig. 2. CTA multiplanar reconstruction showed a filling defect indicating a left atrial mass with maximum dimensions of approximately 7.3 × 5.1 cm. Fig. 1. A. The original stent was completely occluded in the middle of the right coronary artery. An arrow indicates the collateral circulation of the distal coronary artery. B. The guide wire passed through the occlusion site of the distal right coronary artery under the guidance of a retrograde guide wire in the epicardial collateral vessels of the right coronary artery. C. The blood flow of the right coronary artery was smooth after the placement of two stents, but the myocardium was slightly stained, as indicated by the circle. D. The second angiograph shows contrast extravasation as would be seen in the heart of a chronic smoker. A C B D
