Background: Little evidence to date has described the feasibility and diagnostic accuracy of coronary computed tomography angiography (CCTA) with noninvasive fractional flow reserve (CT-FFR) in coronary vessels with resorbable magnesium scaffold (RMS). Methods: The SHERPA-MAGIC is a prospective study enrolling patients receiving RMS. The present analysis considered patients undergoing CCTA 18 months after the index procedure. CCTA images were employed to investigate reabsorption status, luminal measurements, and noninvasive FFR. Three-year follow-up was available for all patients. Results: Overall, 26 patients with a total of 29 coronary arteries treated with 35 RMS were considered. The most frequently involved vessel was left anterior descendent (LAD). Median stent length was 25 (20–25) mm, with a median diameter of 3 (3–3.5) mm. At 18-month CCTA, all scaffolded segments were patent. Complete RMS reabsorption was observed in 27 (93%, 95% CI 77–99%) cases. Median minimal lumen diameter (MLD) and area (MLA) of the scaffolded segments were 2.5 [2.1–2.8] mm and 6.4 [4.4–8.4] mm², respectively. Median CT-FFR was 0.88 [0.81–0.91]. Only one (3.5%) vessel showed a flow-limiting CT-FFR value ≤0.80. During the 3-year follow-up, only one (4%) adverse event was observed. Conclusions: In patients undergoing RMS implantation, CCTA including noninvasive CT-FFR evaluation is feasible and allows investigation of long-term RMS performance.

Background: ST-segment elevation myocardial infarction (STEMI) remains a leading cause of mortality worldwide, primarily caused by acute thrombosis over atherosclerotic plaques. Simultaneous acute thrombosis in two coronary arteries is an exceptionally rare event. This report highlights a unique case of STEMI associated with cardiogenic shock due to dual coronary artery thrombosis and provides insights from a literature review on this rare condition. Methods: We report the case of a 58-year-old male with a history of hypertension, type II diabetes, and heavy smoking, who presented with a two-day history of chest pain and cardiogenic shock. Diagnostic evaluation included an electrocardiogram showing ST-segment elevation in AVR and ischemia, along with echocardiography revealing severe left ventricular dysfunction (ejection fraction 20%). Emergency coronary angiography was performed to identify the underlying pathology. Additionally, a literature review was conducted to analyze the characteristics and outcomes of similar cases of dual coronary artery thrombosis. Results: Coronary angiography identified significant occlusions in the proximal circumflex branch and the left anterior descending artery (LAD), a combination rarely reported in the literature. Our review confirmed that dual thrombosis involving the LAD and right coronary artery (RCA) is the most frequently described presentation of this condition, while simultaneous CFX and LAD thrombosis is exceedingly rare. Most reported cases, including ours, were associated with cardiogenic shock, highlighting the severity of this clinical entity. Despite successful thrombus aspiration and stenting, our patient experienced severe complications, including infections, pleural effusions, and paralytic ileus, ultimately requiring evaluation for left ventricular assist device implantation. Conclusions: This case underscores the complexity and critical challenges of managing STEMI with cardiogenic shock due to simultaneous coronary thrombosis. The findings from our literature review suggest the need for heightened clinical awareness and tailored revascularization strategies. Further studies are warranted to optimize management approaches and improve outcomes in such rare and high-risk scenarios.

Introduction: ST-segment elevation myocardial infarction (STEMI) is a leading cause of death worldwide, commonly caused by acute thrombosis over atherosclerotic plaques. This report presents a rare case of simultaneous acute thrombosis in two coronary arteries, leading to STEMI associated with cardiogenic shock. Case Presentation: A 58-year-old male with a history of hypertension, type II diabetes, and heavy smoking presented with two days of chest pain and was found in cardiogenic shock upon arrival. His ECG showed ST-segment elevation in AVR and ischemia, while echocardiography revealed severe left ventricular dysfunction (EF 20%). Emergency coronary angiography identified significant occlusions in both the proximal circumflex branch and left anterior descending artery (LAD). Despite successful thrombus aspiration and stenting, the patient developed serious complications, including infections, pleural effusions, and paralytic ileus. After nearly two months in the intensive coronary care unit with persistent heart failure, he was referred for evaluation of left ventricular assist device implantation. Conclusion: This case highlights the challenges of managing cardiogenic shock in simultaneous thrombotic events in STEMI, underscoring the need for rapid intervention and tailored management strategies in critically ill patients. Further research is necessary to optimize revascularization approaches and improve outcomes in similar cases.
