The carotid artery intima—media thickness (IMT) is an established surrogate marker of vascular risk. We assessed the common femoral artery IMT and its correlation with coronary artery disease (CAD). We also assessed the influence of vascular risk factors on the femoral IMT. Patients (n = 180; mean age 60.4 ± 10.5 years) who had undergone coronary angiography due to symptoms of CAD were enrolled in this study. We found significantly higher values of femoral IMT in patients with CAD than in those without CAD (P = .0000). A strong positive correlation between femoral IMT and the severity of CAD expressed by the Gensini Score (P = .0000) was observed. There was a positive correlation between femoral IMT and levels of triglycerides (P = .017), body mass index (BMI; P = .036), male gender (P = .0000), and smoking (P = .028). There was a negative correlation between femoral IMT and the level of high-density lipoprotein—cholesterol (P = .001). Femoral IMT could be a novel cardiovascular risk marker.

This study sought to investigate the impact of successful manual thrombus aspiration on angiographic in-stent restenosis and clinical outcome in patients treated by bare metal stent implantation for ST-segment elevation acute myocardial infarction. There are very limited data on the impact of manual thrombus aspiration on the occurrence of in-stent restenosis after bare metal stent implantation. This was a prospective, randomized, single-center study. Patients (N=60) presenting within 12 h of ST-segment elevation acute myocardial infarction symptom onset were randomized to primary percutaneous coronary intervention (PCI) with (N=30) or without (N=30) upfront manual thrombus aspiration using the Export aspiration catheter. All patients underwent control coronary angiography after 6 months. Baseline, clinical, and angiographic preprocedural findings did not differ between the two groups. Patients who underwent successful manual thrombus aspiration had significantly higher minimal lumen diameter after 6 months (2.25±0.90 vs. 1.63±0.76, P=0.005), significantly lower percentage diameter stenosis (28.81 vs. 45.03%, P=0.017), and significantly lower late lumen loss (0.73±0.84 vs. 1.18±0.79, P=0.035). There was a trend for lower rate of major adverse cardiocerebrovascular events such as death, myocardial reinfarction, stroke, and target lesion revascularization in the same group of patients (16.67 vs. 26.67%, P=0.347). Successful upfront manual thrombus aspiration during primary PCI showed beneficial effects on the reduction of in-stent restenosis after bare metal stent implantation compared with standard PCI.

Objectives: To document the real-world experience with the use of pneumatic pulsatile mechanical circulatory support (MCS) with the PulseCath iVAC2L during high-risk percutaneous coronary interventions (HR-PCIs). Background: The use of MCS in HR-PCIs may reduce the rate of major adverse cardiovascular events (MACEs) at 90 days. The PulseCath iVAC2L is a short-term pulsatile transaortic left ventricular (LV) assist device that has been in use since 2014. The iVAC2L Registry tracks its safety and efficacy in a variety of hospitals worldwide. Methods: The iVAC2L Registry is a multicenter, observational registry that aggregates clinical data from patients treated with the iVAC2L worldwide. A total of 293 consecutive cases were retrospectively collected and analyzed. Estimated rates of in-hospital clinical endpoints were described. All-cause mortality was used as the primary endpoint and other outcomes of interest were used as secondary endpoints. The rates obtained were reported and contextualized. Results: The in-hospital rate of all-cause mortality was 1.0%, MACE was 3.1%. Severe hypotension occurred in 8.9% of patients. Major bleeding and major vascular complications occurred in 1.0% and 2.1%, respectively. Acute myocardial infarction occurred in 0.7% of patients. Cerebrovascular events occurred in 1.4% of patients. Cardiac arrest occurred in 1.7% of patients. A statistically significant improvement in blood pressure was observed with iVAC2L activation. Conclusions: The results of the present study suggest that the iVAC2L is capable of improving hemodynamics with a low rate of adverse events. However, confirmatory studies are needed to validate these findings.

Malignant fibrous histiocytoma is an extremely rare primary malignant tumor of the heart. It is usually diagnosed when it is locally aggressive or has already metastasized. The prognosis is poor with an average survival time of one year. We report a case of recurrent left atrial malignant fibrous histiocytoma initially misdiagnosed as myxoma. The patient underwent repeated surgical resections followed by chemotherapy. Despite adjuvant chemotherapy, 18 months after initial diagnosis, definitive tumor relapse in left atrium was diagnosed. This is the 48th case of primary cardiac fibrous malignant histiocytoma reported in the literature.
