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...

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...

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...

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...

Tolvaptan (TLV) is an oral selective vasopressin type 2 receptor antagonist. Long-term use of TLV is not recommended in patients with heart failure (HF) if fluid retention disappears and/or body weight is within the target range. However, some patients require long-term use of TLV. The current study investigated the efficacy and safety of long-term use of TLV. Subjects were 258 consecutive patients with HF who received TLV during hospitalization from January 2011 to March 2015. The rate of continuing administration of TLV was evaluated...

REVIEW
Allison Lee, John P R Loughrey
Ultrasonography is increasingly being viewed as an everyday tool in obstetric anesthesia. For the administration of spinal or epidural anesthesia, it reduces needle redirection attempts in patients with difficult anatomy. In the less frequent scenario of a collapsed patient, it helps with assessment in the form of transthoracic echocardiography. Abdominal blocks require ultrasound guidance for safe and anatomically correct placement. Accurate assessment of gastric volume status with ultrasound would be a useful everyday skill if it is adopted into mainstream practice...

BACKGROUND: 2D-transesophageal echocardiography (TEE) is routinely performed to guide percutaneous ASD closure in children. We aimed to assess whether two-dimensional (2D)-transthoracic echocardiography (TTE) is a safe alternative for assessment and guidance of atrial septal defect (ASD) closure in unselected children. METHODS: We performed a retrospective single-center study including 389 consecutive children aged less than 15-year-old who underwent percutaneous ASD closure under 2D-TEE (1998-2005, n=133) or 2D-TTE (2005-2014, n=256)...

BACKGROUND: Metastatic cardiac tumors are far more common than primary tumors. Although the hematogenous spread of osteosarcoma is well known, the imaging findings of cardiovascular involvement by osteosarcoma are seldom reported and can be difficult to recognize. CASE PRESENTATION: A 21-year-old man of African descent presented to our center complaining of shortness of breath, awareness of heart beats, easy fatigability, swelling of lower limbs, and left-side chest discomfort for the past 6 months getting worse for the last 3 months prior to his third readmission...

Loeffler endocarditis is a complication of hypereosinophilic syndrome resulting from eosinophilic infiltration of heart tissue. We report a case of Loeffler endocarditis in which three-dimensional transthoracic and transesophageal echocardiography provided additional information to what was found by two-dimensional transthoracic echocardiography alone. Our case illustrates the usefulness of combined two- and three-dimensional echocardiography in the assessment of Loeffler endocarditis. In addition, a summary of the features of hypereosinophilic syndrome and Loeffler endocarditis is provided in tabular form...
