Prosthetic valve thrombosis (PVT) is a life-threatening complication in pregnant women with mechanical prosthetic heart valves. Thrombolytic therapy (TT) has evolved as an effective treatment alternative to surgery, which is associated with very high maternal and fetal mortality and morbidity in these patients. Acute ischemic stroke may rarely occur during TT for PVT. Here, we present a pregnant patient who was complicated with cerebral thromboembolism during TT for PVT and successfully managed with continuation of TT.

Behçet’s disease (BD) is an autoimmune disorder affecting multiple organs. Aortic pseudoaneurysm is the most catastrophic lesion in BD. This lesion type is considered as a complicated and challenging pathology by surgeons because of the technical operative difficulties and frequent recurrence. So, the endovascular repair of inflammatory aortic pseudoaneurysm has been used as an alternative to open surgical repair. It is particularly important in patients who are high-risk surgical candidates because of comorbidities. In this report, we present a case and treatment of bronchial obstruction, which caused progressive dyspnea after endovascular repair of aortic rupture, in patient with known history of BD.

The symptoms of aortic dissection (AD) may be highly variable and may mimic other much common conditions. Thus, a high index of suspicion should be maintaned, especially when the risk factors for AD are present or signs and symptoms suggest this possibility. However, sometimes AD may be asymptomatic or progression may be subclinical. Various electrocardiographical (ECG) changes may be seen in AD patients such as ST segment elevation in aVR as well as ST segment depression and T-wave inversion. In this case report, we reported a patient with acute AD whose ECG revealed ST segment elevation in aVR lead in addition to diffuse ST segment depression in other leads.

Introduction

Impaired coronary microcirculation, inflammation, and endothelial dysfunction were reported etiological factors for microvascular angina (MVA). Recently, increased epicardial adipose tissue (EAT) thickness has been associated with hypertension, metabolic syndrome, and coronary artery disease in general population. In this study, we aimed to evaluate the EAT thickness in patients with MVA.

Methods

This study enrolled 200 patients (83 males; mean age: 55.4 ± 8.2 years) who have been diagnosed with MVA and 200 controls (89 males; mean age: 54.4 ± 8.5 years). All patients underwent transthoracic echocardiography, and EAT thickness was measured from a parasternal long-axis view as the hypoechoic space on the right ventricular free wall.

Results

The mean EAT thickness was significantly higher in MVA patients than the controls (5.5 ± 1.1 vs. 4.9 ± 0.7 mm; p < 0.001). Multiple logistic regression analysis showed that increased EAT thickness was an independent predictor of MVA (OR = 1.183, 95% CI = 1.063–1.489; p = 0.023). In receiver operating characteristic curve analyses, EAT thickness above 5.3 mm predicted MVA with a sentivity of 68% and a specificity of 63% (AUC = 0.711, 95% CI = 0.659–0.762; p < 0.001).

Conclusions

The EAT thickness was observed significantly higher in MVA patients as compared to controls. Increased EAT thickness may be associated with mechanisms that play a major role in the pathogenesis of MVA.
