Contrast-enhanced computed tomography (CT) is an effective tool for assessment of thoracic aortic disease in the modern era. Here, we describe a case of Type A aortic dissection incidentally detected by CT in a 63-year old man. Upon more precise imaging with electrocardiography (ECG)-gated CT, the dissection vanished, revealing it to be an aortic motion artifact. This report highlights the importance of motion artifacts mimicking a dissection flap. CT imaging gated with ECG can distinguish a dissection flap from an artifact.

Fluoroquinolones (FQs) are one of the most commonly prescribed classes of antibiotics. Their high tissue distribution and broad-spectrum antibacterial coverage make their use very attractive in numerous infectious diseases. Although generally well tolerated, FQs have been associated with different adverse effects including dysglycemia and arrhythmias. FQs have been also associated with a series of adverse effects related to collagen degradation, such as Achilles tendon rupture and retinal detachment. Recently, an association between consumption of FQs and increased risk of aortic aneurysm and dissection has been proposed. This article reviews the pathogenesis of thoracic aortic diseases, the molecular mechanism of FQ-associated collagen toxicity, and the possible contribution of FQs to aortic diseases.

Thoracic aortic aneurysm is a typically silent disease characterized by a lethal natural history. Since the discovery of the familial nature of thoracic aortic aneurysm and dissection (TAAD) almost 2 decades ago, our understanding of the genetics of this disorder has undergone a transformative amplification. To date, at least 37 TAAD-causing genes have been identified and an estimated 30% of the patients with familial nonsyndromic TAAD harbor a pathogenic mutation in one of these genes. In this review, we present our yearly update summarizing the genes associated with TAAD and the ensuing clinical implications for surgical intervention. Molecular genetics will continue to bolster this burgeoning catalog of culprit genes, enabling the provision of personalized aortic care.

Coronary aneurysms are defined as localized dilatations of the coronary arteries. In this review, we will analyze the most important aspects of this rare condition while trying to provide answers to the following questions: What is a coronary aneurysm? What causes coronary aneurysm? Do coronary aneurysms cause symptoms? Can coronary aneurysms rupture? How do we treat coronary aneurysms?.

Background Both open and endovascular treatments of descending thoracic aortic aneurysms require a secure proximal landing zone. This may be difficult to achieve when the dilatation extends proximally to the left subclavian level. Clamping above the aneurysm may be difficult. In the case of an endovascular approach, achieving a suitable landing zone may require extensive extra-anatomic debranching, which is not without complications and limitations.Methods We describe a modification of the traditional elephant trunk procedure that represents a “stand-alone” elephant trunk. Under deep hypothermic circulatory arrest, the aorta is transected between the left carotid and left subclavian arteries. A simple, noninverted elephant trunk is placed through the distal cut aorta. The two ends are sewn back together, incorporating the lip of the elephant trunk in the anastomosis. We review our experience in five patients who underwent this procedure.Results All 5 patients (4 males, 1 female) aged 41 to 68 (mean, 57 years) tolerated the Stage 1 stand-alone elephant trunk procedure well, without mortality, stroke, or bleeding. The Stage 2 descending aortic replacements were performed at a mean of 6.7 months after Stage 1. There was no Stage 2 mortality, stroke, or bleeding. One patient died 8 years later of cardiac cause, and the remaining are alive and well.Conclusion A stand-alone elephant trunk procedure is safe and straightforward and provides an excellent proximal foundation for subsequent open (or potentially endovascular) descending aortic replacement.
