The importance of bedside echocardiographic assessment in emergency admissions with probable acute coronary syndromes: A case of an unruptured giant ascending aorta aneurysm.

Symptomatic aortic aneurysms can manifest in different clinical settings, such as acute coronary syndrome (ACS), acute heart failure, a shock that is mostly due to the complications related to dissection or rupture of the aneurysm. In these clinical settings, the diagnosis can be established with the help of medical history, physical examination, and promptly performed imaging tests. However, the diagnosis of an asymptomatic aortic aneurysm is usually incidental. Thus, it is very rare to find a case of ACS with intact aortic aneurysm and without obstructive coronary artery disease. In this paper, we report a successfully treated male patient aged 41 years with intact ascending aortic aneurysm who presented with ACS and was diagnosed with the help of bedside echocardiographic assessment.

The Role of Coronary Computed Tomography Angiography in Evaluation of High Troponin Patients with Narrow-Complex Supraventricular Tachycardia.

Aim: The aim of this study was to investigate the relation of high-sensitive cardiac troponin T (hs-cTnT) elevation with characteristics of supraventricular tachycardia (SVT) episode (duration and maximum heart rate) and coronary computed tomography angiography (CCTA) findings in patients with SVT who presented to the emergency room with palpitation. Methods: This retrospective, single-center, noninvasive study included all patients aged between 18 years and 65 years who presented to the emergency department due to narrow-complex SVT and underwent CCTA to rule out coronary artery disease (CAD) due to elevation of hs-cTnT and reverted back to sinus rhythm after intravenous adenosine. The first, second, and the maximum hs-cTnT levels were obtained from the database. The patients were classified into normal coronaries, nonobstructive CAD, and obstructive CAD according to findings of the CCTA. The findings of the groups were compared. Results: Eighty-five patients were enrolled in the study. Of them, 21 (26%) patients were female. Sixty-three patients (74%) had normal coronary arteries as per CCTA results, whereas 22 patients (22%) had nonobstructive CAD and two patients (2%) had obstructive CAD. The groups did not differ statistically in respect to hs-cTnT measurements, duration of the arrhythmia, and maximum heart rate at SVT episode. There was no significant statistical correlation between hs-cTnT and the study parameters except the maximum heart rate. Conclusion: Cardiac troponins may increase in patients with paroxysmal SVT irrespective of the presence of coronary lesions, and the CCTA may not be an appropriate investigation in the differential diagnosis of paroxysmal SVT with elevated hs-cTnT.
