Coronary fistulas are rare, not gender-specific congenital conditions, consisting of communications between the coronary arteries and either another coronary vessel or a cardiac chamber. In contrast to large fistulas, small fistulas, named "minimae cordis veneae" or the Thebesius venous system, are draining into heart chambers and form a vascular network in the cardiac lumen. In this article, we present the case of a 72-year-old female with a significant history of cardiovascular disease, admitted to our clinic because of rest dyspnea, fatigue, and minimal chest pain. The 12-lead electrocardiogram showed a trifascicular block (a second-degree atrioventricular block Mobitz II, associated with a right bundle branch block and left anterior fascicle block) and negative T waves in DII, DIII, aVF, V4-V6 leads. An invasive coronary angiography was performed, which revealed no significant atherosclerotic lesions. However, a persistent capillary blush was present at the apex site of the left ventricular chamber, draining from the distal segments of both the anterior descending coronary artery and the posterior interventricular coronary artery. The intramural vascular network generating a left ventricle angiogram image of this kind was suggestive for persistent Thebesian vessels connecting the two coronaries with the left ventricular chamber.

Introduction: Pulmonary embolism (PE) is the most common cause of vascular death after myocardial infarction and stroke, being associated with high mortality and morbidity rates. The aim of this study was to assess the factors related to 1-year mortality in patients with acute pulmonary embolism who survived the acute event. Material and methods: In total, 104 patients who had survived the acute episode of pulmonary embolism and underwent a one-month follow-up after the acute event were included in the study. The patients were divided into two groups: Group 1 – patients who had survived at one year after being diagnosed with acute PE (80.76%, n = 84), and Group 2 – patients who had died after one year (19.23%, n = 20). Results: There were no differences between the 2 groups in relation to gender (p = 0.3), or cardiovascular risk factors (diabetes: p = 0.5, smoking: p = 0.3, hypertension: p = 1, hypercholesterolemia: p = 0.5, hypertriglyceridemia: p = 0.4). Patients who had deceased were significantly older (73.35 ± 9.37 years vs. 66.36 ± 11.17 years, p = 0.005) and had a higher weight compared to the survivors (85.8 ± 21.09 kg vs. 75.89 ± 22.69 kg, p = 0.03). Left ventricular ejection fraction, measured by cardiac ultrasound, was significantly lower in the deceased group compared to survivors (45.63 ± 8.9% vs. 52.86 ± 6.8%, p = 0.03). Multivariate analysis identified the hemodynamic instability (OR = 3.17, p = 0.007), the presence of left QRS axis deviation (OR = 4.81, p = 0.001), associated pulmonary pathologies (OR = 3.2, p = 0.02) as well as the presence of chronic kidney disease (OR = 5, p = 0.04) as the most powerful predictors of death at 1 year in patients with acute PE surviving the acute event. Conclusions: Factors associated with a higher mortality rate at 1 year in patients who had survived at 1 month following an acute pulmonary embolism episode included: older age, higher body weight, presence of associated pulmonary pathologies, chronic kidney disease, left axis deviation, low left ventricular ejection fraction, hemodynamic instability requiring inotropic support, cardiogenic shock at presentation or cardiac arrest during the acute phase.

Atrial fibrillation (AF) is the most frequent form of supraventricular arrhythmia in medical practice. It is characterized by chaotic electrical activity in the atria, which often leads to irregular and fast ventricular contractions. Pulmonary veins (PV) play an essential part in the genesis of AF. There are a series of risk factors that trigger the development and recurrence of AF after PV isolation. Despite advanced medical technology, the success rate of AF ablation is not satisfactory. The purpose of this study is to assess the preprocedural imaging and serum biomarkers linked to an increased recurrence of AF after PV isolation. The primary endpoint is represented by AF recurrence after PV isolation. In addition, the rate of cardiovascular death and the rate of major adverse cardiovascular events will be assessed in relation to the enlargement of the left atrium and the volume of epicardial adipose tissue surrounding the heart.

Introduction This study aimed to investigate the correlation between multislice computed tomography (MSCT)-derived parameters characterizing atrial enlargement and the frequency of emergency hospitalizations after catheter ablation for atrial fibrillation (AF). Methods The study included 52 patients with paroxysmal or persistent AF, who presented criteria for interventional rhythm control strategies and underwent MSCT evaluation prior to ablation. Results The majority of emergency hospital admissions were due to heart failure caused by high-frequency arrhythmia (90.33%), or by cardioembolic complications, causing acute stroke (9.67%). The number of emergency referrals was significantly increased in cases of moderately enlarged left atrial volume (69.23%), and re-admission was necessary for over three quarters of the patients with highly enlarged left atrial volume (76.92%, p = 0.02). The average recurrence rate of AF following ablation therapy was 28.84% during the one-year follow-up, being 0% for volumes <71.33 mL, 32% for volumes between 71.33 mL and 109.5 mL, and 53.84% for volumes >109.5 mL (p = 0.01). Conclusion A large volume of the left atrium, determined by MSCT, is associated with a higher risk of emergency rehospitalizations following catheter ablation of AF.

New imaging tools have been developed in recent years to rapidly and accurately diagnose life-threatening diseases associated with high mortality rates, such as acute coronary syndromes, acute aortic dissection, or pulmonary embolism. The concept of using computed tomographic (CT) assessment in emergency settings is based on the possibility of excluding multiple acute pathologies within one scan. It can be used for patients complaining of acute chest pain of unclear etiology with the possible association of acute coronary dissection or pulmonary embolism, but only a low to moderate risk of developing an acute coronary syndrome. One of the benefits of this protocol is the possibility of decreasing the number of patients who are hospitalized for further investigations. The technique also allows the rapid triage of patients and the safe discharge of those who show negative results. The aim of this review is to summarize the current medical literature regarding the potential use of CT for the triple rule-out (TRO) of coronary etiologies.

Invasively determined fractional flow reserve (FFR) represents the gold-standard method for the functional evaluation of coronary lesions. Coronary computed tomography angiography (CCTA) provides characterization of the coronary anatomy, with important morphological information on the atherosclerotic plaques, but does not offer a hemodynamic evaluation of coronary artery lesions. CT evaluation of FFR (FFRCT) is a new noninvasive diagnostic method, which provides anatomical and functional assessment of the whole coronary tree, based on computational techniques, with no more radiation or hyperemic agent administration compared with routine CCTA. Recent studies demonstrated the safety and accuracy of FFRCT and its therapeutic use and cost benefits in real-world clinical use.

Cardiac magnetic resonance imaging is an evolving imaging method that can be used in cardiovascular pathology evaluation. Technological developments have increased the clinical utility of cardiac magnetic resonance in the exploration of various cardiac abnormalities. The most important imaging techniques and their utility will be presented in this review, together with the advantages and limitations of cardiac magnetic resonance and with a brief presentation of common cardiac disorders that can be assessed by cardiac magnetic resonance including ischemic heart disease, cardiomyopathies and myocarditis.
