Every catheter laboratory is equipped with an X-ray system designed to provide fluoroscopic imaging of the heart. Although cardiac catheters are well visualized in all X-ray imaging, the soft tissue of myocardium is not. Therefore the imaging of the cardiac chambers is indirect through relation to the cardiac silhouette. However, fluoroscopy can be used to detect complications from the invasive procedures in the cardiac catheterization laboratory, such as cardiac tamponade where the excursion of the cardiac silhouette decreases, and visceral and parietal pericardium are seen separated by the blood of accumulation in the pericardial cavity...

Calcified nodules in human coronary arteries are usually focally distributed. Non-invasive imaging of coronary arteries by bedside emergency transthoracic echocardiography in adults is possible and may become a useful adjunct to other methods of coronary artery examination. Coronary artery stenosis can be identified as localized color aliasing and accelerated flow velocities. Complete visualization of individual ostial coronary segments might ease the demonstration of coronary stenosis by bedside transthoracic echocardiography...

The present translational study aimed to verify whether serial (18)F-fluoro-deoxyglucose Positron Emission Tomography/Computed Tomography (FDG-PET/CT), predicts doxorubicin cardiotoxicity. Methods: Fifteen athymic mice were treated with intravenous administration of saline (n = 5), doxorubicin 5 mg/Kg (n = 5) or doxorubicin 7.5 mg/Kg (n = 5) and submitted to dynamic microPET scan to estimate left ventricular glucose consumption (LV-MRGlu) before and after chemotherapy. Thereafter, we retrospectively identified 69 patients successfully treated with Adriamycin, Bleomycin, Vinblastine, and Dacarbazine (ABVD) regimen for Hodgkin's Disease (HD) and submitted to four consecutive FDG-PET/CT scans...

REVIEW
Romain Pariaut
A rate control or a rhythm control strategy can be applied to the management of atrial fibrillation. Rate control of atrial fibrillation consists of decreasing the ventricular response rate by limiting the number of supraventricular impulses that can travel through the atrioventricular node. The goal of decreasing heart rate in dogs with atrial fibrillation is usually achieved with a combination of the calcium channel blocker diltiazem and digoxin. Rhythm control of atrial fibrillation encompasses pharmacologic and nonpharmacologic methods to terminate the arrhythmia and restore sinus rhythm...

Takotsubo syndrome is an acute reversible heart failure syndrome triggered by physical or emotional stress, especially in postmenopausal women. Herein, we describe a case of a 31-year-old pacemaker dependent lady who presented with syncope after she was bereaved of her father. Electrocardiogram at admission revealed ventricular paced rhythm at 60/min, prolonged QT interval and frequent runs of torsades de pointes. Transthoracic echocardiogram and left ventriculogram revealed findings typical of Takotsubo syndrome...

We describe a preoperative transthoracic echocardiography consult service led by anesthesiologists. The implementation process and the patient cohort are described. Preoperative transthoracic echocardiographic examinations were mostly performed in patients undergoing intermediate- or high-risk noncardiac surgery and in patients with a higher calculated mortality risk. All transthoracic echocardiographic examinations were interpreted by anesthesiologists.

Post-myocardial infarction ventricular septal defect corresponds to the rupture of the ventricular septum between the healthy and infarcted parts. It is a rare complication still associated with a high mortality rate. Its diagnostic should be evoked in case of pathologic cardiac auscultation and confirmed by emergent transthoracic echocardiography. Hemodynamic stabilisation, mainly with the insertion of an intra-aortic balloon pump is the first step in the management. The subsequent modality of closure, either surgical or transcatheter, as well as the ideal timing should be discussed in the Heart team...

BACKGROUND: Chest pain is a common presenting symptom in the emergency department (ED). Although the diagnostic workup for chest pain is well established, the best time to perform invasive cardiac catheterization in patients with low to moderate risk of coronary artery disease is still unclear, particularly if noninvasive tests such as the electrocardiogram (ECG) and nuclear myocardial perfusion scan show nonsignificant findings. CASE REPORT: We present the case of a 52-year-old female who presented to the ED with acute-onset chest pain that had started early in the morning while she was sleeping...

Aims: Survival in pulmonary hypertension (PH) relates to right ventricular (RV) function. However, the RV unique anatomy and structure limit 2D analysis and its regional 3D function has not been studied yet. The aim of this study was to assess the implications of global and regional 3D RV deformation on clinical condition and survival in adults with PH and healthy controls. Methods and results: We collected a prospective longitudinal cohort of 104 consecutive PH patients and 34 healthy controls between September 2014 and December 2015...

Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents the initial manifestation of the disease. We report the case of a 75-year-old woman with a metastatic neuroendocrine tumor admitted to the emergency room for fatigue and heart failure...

BACKGROUND: Transcranial Doppler echocardiography and transthoracic echocardiography may detect with high accuracy right-to-left shunt (RLS) due to patent foramen ovale (PFO). However, a standardized diagnostic protocol has never been established. It has been suggested that standing or sitting positions may improve sensitivity of transcranial Doppler due to increased LRS in such positions. We aimed to test efficacy of the sitting position in addition to the supine position in the grading of RLS in patients with PFO...

Christopher J Broyd, Fausto Rigo, Justin Davies
Wave intensity analysis is calculated from simultaneously acquired measures of pressure and flow. Its mathematical computation produces a profile that provides quantitative information on the energy exchange driving blood flow acceleration and deceleration. Within the coronary circulation it has proven most useful in describing the wave that originates from the myocardium and that is responsible for driving the majority of coronary flow, labelled the backward decompression wave. Whilst this wave has demonstrated valuable insights into the pathogenic processes of a number of disease states, its measurement is hampered by its invasive necessity...

Integration of volumetric heart chamber quantification by 3D echocardiography into clinical practice has been hampered by several factors which a new fully automated algorithm (Left Heart Model, (LHM)) may help overcome. This study therefore aims to evaluate the feasibility and accuracy of the LHM software in quantifying left atrial and left ventricular volumes and left ventricular ejection fraction in a cohort of patients with a bicuspid aortic valve. Patients with a bicuspid aortic valve were prospectively included...

In recent years, the spread of more-sensitive diagnostic methods has resulted in an increase of synchronous multiple primary lung cancer diagnosis. Nevertheless, its occurrence is still rare. Distinction between synchronous lesions from second independent primary tumors is a problem when dealing with multiple lung tumors, particularly if the histological type is the same. We present a case report of a 78-year-old female patient referred to our institution due to pneumonia. A subsequent thoracic computed tomography (CT) was performed showing two suspicious lesions, one in the right upper lobe and the other in the right inferior lobe...
