A 28-year-old Filipino male was admitted due to high-grade fevers and dyspnea on a background of chronic cough and weight loss. Due to clinical and echocardiographic signs of cardiac tamponade, emergency pericardiocentesis was performed on his first hospital day. Five days after, chest radiographs showed new pockets of radiolucency within the cardiac shadow, indicative of pneumopericardium. On repeat echo, air microbubbles admixed with loculated effusion were visualized in the anterior pericardial space. Constrictive physiology was also supported by a thickened pericardium, septal bounce, exaggerated respiratory variation in AV valve inflow, and IVC plethora...

We report a case of delayed treatment of a partial aortic valve leaflet avulsion during transcatheter aortic valve replacement (TAVR) and its successful management by a percutaneous snare retrieval technique. Post-TAVR transesophogeal echocardiography showed an avulsed native valve leaflet. We deferred retrieval of the mass with anticoagulant agents. One month later, a 30-mm EN-Snare was used to snare the mass. This case report demonstrates that the management of an avulsed aortic valve leaflet can be safely deferred with the use of an anticoagulant agent...

There has been tremendous growth in the population of adults with congenital heart disease (CHD) over the last few decades because of advances in medical care. Whereas some cases are cured during childhood, most patients instead undergo palliation, which leaves them at risk for late complications. Lifelong clinical follow-up involving serial multimodality imaging is helpful to monitor and guide the treatment of late complications. Imaging of these individuals is challenging because of their unique anatomy and therefore requires careful consideration on a case-by-case basis...

BACKGROUND Carbon dioxide (CO2) is believed to be the safest gas for laparoscopic surgery, which is a standard procedure. We experienced severe cerebral infarction caused by paradoxical CO2 embolism during laparoscopic liver resection with injury of the hepatic vessels despite the absence of a right-to-left systemic shunt. CASE REPORT A 60-year-old man was diagnosed with hepatocellular carcinoma in the right hepatic lobe secondary to alcoholic liver disease. We planned the laparoscopy-assisted liver resection...

REVIEW
Xavier Monnet, Jean-Louis Teboul
BACKGROUND: For complex patients in the intensive care unit or in the operating room, many questions regarding their haemodynamic management cannot be answered with simple clinical examination. In particular, arterial pressure allows only a rough estimation of cardiac output. Transpulmonary thermodilution is a technique that provides a full haemodynamic assessment through cardiac output and other indices. MAIN BODY: Through the analysis of the thermodilution curve recorded at the tip of an arterial catheter after the injection of a cold bolus in the venous circulation, transpulmonary thermodilution intermittently measures cardiac output...

BACKGROUND: Estimation of sudden cardiac death (SCD) risk is an integral part of clinical management of patients with hypertrophic cardiomyopathy (HCM). Identification of novel biomarkers of this disease can provide additional criteria for SCD risk stratification. Soluble suppression of tumorigenicity (sST2) and galectin-3 (Gal-3) are useful biomarkers for prognosis of heart failure (HF). Both of them appear to mediate cardiac fibrosis - an important pathogenetic process in HCM. Data about sST2 and Gal-3 usefulness in patients with HCM are limited...

Pulmonary thromboembolism is a life-threatening disease, particularly during pregnancy. We report a case of successful cardiopulmonary resuscitation followed by surgical thrombectomy in a 35-year-old woman at 28 weeks of gestation. Intracardiac echocardiography was percutaneously located behind the uterus, and greatly assisted monitoring of the foetal condition and haemodynamic status.

Over the last decade and a half there has been much interest in understanding the role of epicardial adipose tissue (EAT) in cardiac pathology. EAT is a visceral adipose deposit with putative paracrine function. In the non-diseased state, EAT releases cardioprotective cytokines and chemokines to the coronary vasculature. In pathological states, EAT releases an inflammatory cytokine profile that is believed to contribute to the development and progression of coronary artery disease (CAD). EAT imaging with echocardiography, computed tomography, and magnetic resonance imaging has demonstrated a correlation between EAT size and CAD...

BACKGROUND: There is increasing evidence that using frequent invasive measures of pressure in heart failure patients results in improved outcomes compared to traditional measures. Admittance, a measure of volume derived from pre-existing defibrillation leads is proposed as a new technique to monitor cardiac hemodynamics in patients with implantable defibrillators. OBJECTIVES: The goal of this work was to evaluate the accuracy of a new ventricular volume sensor (VVS, CardioVol), compared with 3D Echocardiography (echo) in patients with implantable defibrillators...

OBJECTIVE: There is now increasing awareness about the need for early diagnosis in patients presenting with chest pain. Pre-hospital delay remains a major hurdle in the institution of early reperfusion therapy, which is crucial in salvaging 'at-risk' myocardium and reducing adverse cardiovascular events following ST elevation myocardial infarction (STEMI). This study aims to determine the incidence and the determinants of delayed presentation STEMI and the potential impact of such delay on adverse cardiovascular outcomes...

Accumulation of excess iron in heart can lead to cardiac dysfunction, which is the most common cause of death in thalassemia major patients. Biopsy is an invasive procedure and therefore not an ideal option to assess iron load. However, standard/usual non-invasive methods, such as ferritin measurement, have some limitations and the results show poor correlations with iron load. Magnetic Response Imaging (MRI-T2*), as a non-invasive and reliable method for iron load assessment in organs such as liver and heart, can be suggested as a favorable alternative...

BACKGROUND: Cardiac output (CO) monitoring is a valuable tool for the diagnosis and management of critically ill patients. In the critical care setting, few studies have evaluated the level of agreement between CO estimated by transthoracic echocardiography (CO-TTE) and that measured by the reference method, pulmonary artery catheter (CO-PAC). The objective of the present study was to evaluate the precision and accuracy of CO-TTE relative to CO-PAC and the ability of transthoracic echocardiography to track variations in CO, in critically ill mechanically ventilated patients...

PURPOSE: Pulmonary hypertension (PH) is characterized by abnormally increased pulmonary vascular pressure, leading to deteriorated right ventricular function and premature death. Pulmonary mean transit time (PMTT) and biventricular function response to exercise in first-pass radionuclide angiography (FP-RNA) may provide early detection and timely disease monitoring of PH. This study aimed to investigate the diagnostic and prognostic values of this imaging modality in PH patients. METHODS: Left and right ventricular ejection fraction (LVEF/RVEF) and PMTT at rest and immediately after exercise treadmill test were measured by FP-RNA in 77 consecutive patients with clinical presentations suggestive of PH (aged 46 ± 15 years, 33 men), mostly with symptoms of unexplained progressive dyspnea...

BACKGROUND: Kawasaki disease (KD) is an acute systemic vasculitis that occurs in children and may lead to cardiovascular morbidity and mortality. Progressive coronary dilatation for at least 2 months is associated with worse late coronary outcomes in patients with KD having medium or giant aneurysms. However, the risk factors and occurrence of progressive coronary dilatation in patients with KD but without medium or giant aneurysms have been insufficiently explored. METHODS: We retrospectively enrolled 169 patients with KD from a tertiary medical center in Taiwan during 2009-2013...
