Case report: Strong low-density-cholesterol reduction accompanied by shrinkage of low-attenuation coronary plaque during lipid-lowering treatment with bempedoic acid—serial evaluation by coronary computed tomography angiography

Here, we present a patient with coronary artery disease and prior percutaneous coronary interventions. This patient had to discontinue taking multiple statins and ezetimibe due to intolerance with musculoskeletal complaints and nausea. Monotherapy with bempedoic acid was well tolerated and was exceptionally effective at lipid lowering, enabling patients to achieve the low-density lipoprotein target of <55 mg/dl, as recommended by current guidelines. In addition, serial coronary computed tomography angiography performed upon clinical indications, during 20 months of lipid-lowering treatment with bempedoic acid, demonstrated signs of favorable plaque component modification, with shrinkage of the low-attenuation plaque component compared to baseline findings

Successful Conservative Treatment of Mobile Aortic Thrombus Causing Acute Limb Ischemia.

In this clinical vignette, we present the case of an 83-year-old female patient with acute limb ischemia, resulting from a large (1.8 × 2.8 cm) mobile thrombus in the descending aorta. The peripheral obstruction was treated with mechanical thrombectomy, whereas the intra-aortic thrombus was treated conservatively with clopidogrel and fondaparinux. (Level of Difficulty: Beginner.)

The Role of Atherectomy in Peripheral Artery Disease: Current Evidence and Future Perspectives

An ageing population and the increasing prevalence of cardiovascular risk factors have aggravated the burden of peripheral artery disease (PAD). Despite advances in the pharmacological treatment of atherosclerosis, many patients with symptomatic PAD require invasive procedures to reduce the symptoms of claudication, salvage tissue and prevent amputation and subsequent disability in those with critical limb ischaemia. After significant advances in endovascular treatment over the past two decades, these techniques are widely accepted as first-choice treatment in the majority of patients with PAD. However, in patients with severely calcified lesions, standard endovascular treatment such as plain or drug-coated balloon (DCB) angioplasty may fail due to vessel recoil or severe dissection in the acute setting, and intimal hyperplasia in the long term. With the use of percutaneous plaque modification and debulking techniques based on atherectomy, such calcified lesions can be tackled more easily after removal or fragmentation of atherosclerotic plaque. More homogeneous balloon expansion at lower pressures can be achieved after atherectomy, which reduces barotrauma while allowing better drug delivery to the vessel wall during DCB angioplasty avoids the need for stent placement. There are four principal methods of direct atherectomy available at the present time: directional atherectomy, rotational atherectomy, orbital atherectomy and hybrid atherectomy. In this article, we provide a short overview of these techniques and the current evidence from clinical trials to support their use

Single Coronary Artery with Anomalous Rising of the Right Coronary Artery: A Rare Coronary Anomaly Diagnosed by 256-Multidetector Computed Tomography

Herein we report the diagnostic potential of cardiac computed tomography (cCT) to delineate the origin and course of an anomalous right coronary artery (RCA) originating from the midpart of the left anterior descended artery (LAD) in an adult with no other form of congenital heart disease. The patient was referred to our institution due to exertional dyspnea and suspected coronary artery disease. The patient underwent X-ray coronary angiography, and no high grade lesions were observed in the left coronary vessels. In the course of the mid-left-anterior-descending artery (LAD), an anomalous side branch coursing away from the left circumflex coronary artery (LCX) was observed, while a right coronary ostium could not be depicted. cCT confirmed the absence of a right coronary ostium, and the vessel originating from the mid LAD was identified as an anomalous RCA, which coursed anterior of the aorta and the pulmonary trunk
