A Surviving Case of Myocardial Infarction with Ventricular Septal Rupture and Ventricular Aneurysm following Gastrointestinal Bleeding.

A 55-year-old man presented to the emergency department with worsening shortness of breath 1 month after a gastrointestinal bleed. He had congestive heart failure, and an electrocardiogram suggested ischemic heart disease involvement. Echocardiography revealed a ventricular septal defect complicated by a left ventricular aneurysm in the inferior-posterior wall. Conservative treatment was started, but hemodynamic collapse occurred on the third day of admission and coronary angiography revealed a revascularizing lesion in the right fourth posterior descending coronary artery. Subsequently, his hemodynamic status continued to deteriorate, even with an Impella CP® heart pump, so ventricular septal defect patch closure and left ventricular aneurysm suture were performed. His condition improved and he was discharged on day 23 of admission and was not readmitted within 6 months after the procedure. Hemodynamic management of ventricular septal defects requires devices that reduce afterload, and clinicians should be aware of the risk of myocardial infarction after gastrointestinal bleeding.

Initial thickness of the crescent may not be a reliable predictor of complications in type A intramural haematoma.

OBJECTIVES: This study aimed to investigate changes in haematoma thickness during the early period and their association with disease progression in patients who received initial medical treatment for type A intramural haematoma (IMH). METHODS: Medical records and serial computed tomography angiography (CTA) images of patients who did not undergo emergency aortic repair for type A IMH upon presentation were retrospectively reviewed. The haematoma remodelling rate was determined using the following equation: thickness of the haematoma on the first CTA (mm) - thickness of the haematoma on the second CTA (mm)time between the first and second CTAs (h). RESULTS: Among the 40 patients included in this study, 38 were indicated for initial watch-and-wait strategy, whereas 2 were indicated for emergency aortic repair but declined it. During hospitalization, 10 patients developed disease progression, with 2 in-hospital mortality cases. Analysis of the haematoma remodelling rate in 39 patients revealed that such a rate was significantly associated with the reciprocal of the time from onset. Analysis of all 70 CTA examinations performed within 24 h after the onset of IMH showed that haematoma thickness was significantly associated with the logarithm of the time from onset. Initial regression of the haematoma was not necessarily associated with avoidance of disease progression. CONCLUSIONS: In type A IMH, the thickness of the haematoma in the ascending aorta tended to decrease in the very early period; however, prompt regression of the haematoma was not necessarily associated with avoidance of disease progression.
