Chest pain showing precordial ST-segment elevation in a 96-year-old woman with right coronary artery occlusion: A case report

Figure 1 Twelve-lead electrocardiograms showed dynamic changes in precordial ST-segment elevation before coronary angiography. A: Electrocardiogram obtained on admission; B: Electrocardiogram obtained two hours after admission.

Figure 2 Coronary angiographic results. A: Acute total occlusion of the proximal portion of the right coronary artery (orange arrow); B: Mild atherosclerosis of the left anterior descending artery and 75% stenosis in the left circumflex artery; C: Fresh thrombus was acquired from the right coronary artery; D: Coronary angiography showed restoration of the right coronary artery after percutaneous coronary intervention.
