Long-Term Change in Flow Rates in Patients with Coronary Slow Flow.

INTRODUCTION: Coronary slow flow (CSF) is a condition characterized by impaired blood flow rates in the coronary arteries. It can result in severe cardiovascular outcomes. There is no sufficient evidence regarding the certain etiology and reversibility of slow flow patterns and changes in frame counts with long-term management. METHODS: We retrospectively enrolled 48 patients with chronic coronary syndrome and CSF who underwent a second angiography. A corrected coronary frame rate (CFR) >27 was defined as CSF. We created 3 groups according to the change in CSF status as the improved, not changed, and worsened groups. We compared the CFR and CSF status of the patients between the first and second angiographies within a median of 2.6 years. RESULTS: We determined a nonsignificant change in cCFR in left anterior descending (LAD) artery (34.4 [18.9] vs. 31.59 [10.3], p = 0.35), circumflex (Cx) artery (42.84 [12.56] vs. 40.66 [13.2], p = 0.35), and right coronary artery (RCA) (57.80 [30.13] vs. 50.32 [19.5], p = 0.11). In the comparison of CSF status of LAD (75% vs. 63%, p = 0.27), Cx (96% vs. 83%, p = 0.09), RCA (94% vs. 94%, p = 1.0) between first and second angiographies, there was no significant change. In the comparison of the 3 groups according to the improvement of CSF status, there was no significant difference in demographic features, change in laboratory parameters, and time between the groups. CONCLUSION: There was no significant change in the median CFR and CSF status in the overall group between the two angiographies after 3 years.

Primary Right Atrial Cardiac Angiosarcoma in Patient With Poland Syndrome: Case Report and Review of the Literature.

This article presents the case of a 24-year-old woman with Poland syndrome who developed primary right atrial cardiac angiosarcoma. The patient presented to the hospital with dyspnea and chest pain, and imaging studies revealed a large mass attached to the right atrium. Urgent surgery was performed to remove the tumor, and the patient underwent adjuvant chemotherapy afterward. Follow-up exams showed no signs of the tumor or any complications from treatment. Poland syndrome is a rare congenital disorder characterized by the absence of unilateral large pectoral muscle, ipsilateral symbrachydactyly, and other malformations of the anterior chest wall and breast. Although the condition does not predispose patients to malignancy, different pathologies can be seen in these patients due to the unknown etiology of the syndrome. Primary right atrial cardiac angiosarcoma is a rare malignancy, and its coexistence with Poland syndrome has not been well established in the literature. This case report highlights the need to consider cardiac angiosarcoma as a possible diagnosis in patients with Poland syndrome who present with cardiac symptoms.

Atrial fibrillation-related acute myocardial infarction and acute mesenteric ischemia.

Atrial fibrillation-related synchronous thromboembolism of the mesenteric and coronary arteries is a rare event. This case report is about an 82-year-old male patient who presented to the emergency department with epigastric pain and who was diagnosed with ST-elevated myocardial infarction accompanied with acute mesenteric ischemia. To our knowledge, this is the first report of angiographic evidence of synchronous thrombus in both the arteries.
