In the era of catheter intervention, the surgical repair of coronary arteriovenous fistula needs to be free from residual shunt. Intraoperative epicardial 15-MHz echocardiography helps to find the residual shunt after ligation or obliteration of anomalous vessels. Here we report our method of the echo-assisted surgical repair of coronary arteriovenous fistula in 7 adult patients. The method made the operation for coronary arteriovenous fistula free from residual shunt, but care should be taken to the development of new vessels after the operation...

BACKGROUND: Interventional closure of the left atrial appendage (LAA) in patients with non-valvular atrial fibrillation, high thromboembolic and bleeding risk or bleeding history is an alternative therapeutic strategy to oral anticoagulation. It is not known if the exclusion of the LAA from the blood circulation affects the left atrial volume (LAV) and consequently its prognostic value or the circulatory performance of the heart in humans. METHODS: We aimed to prospectively assess potential changes in baseline LAV, left ventricular ejection fraction (LVEF), NT-proBNP-level and the covered distance in the 6-min walk-test 6 weeks and 6 months after LAA closure with the WATCHMAN™ device...

Following an ischemic event post systolic shortening (PSS) may occur. We investigated the association between PSS in patients with ST-segment elevation myocardial infarction (STEMI) following primary percutaneous coronary intervention (pPCI) and occurrence of cardiovascular events at follow-up. A total of 373 patients admitted with STEMI and treated with pPCI were prospectively included in the study cohort. All patients were examined by echocardiography a median of 2 days after admission (interquartile range, 1-3 days)...

OBJECTIVES: Intraoperative focused transthoracic echocardiography (TTE) is feasible and has an effect on the management of hemodynamically unstable surgical patients. Furthermore, in noncardiac thoracic surgery, TTE might provide additional information for hemodynamic treatment. Transthoracic accessibility during thoracic surgical interventions is assumed to be difficult. For patients positioned on their right side, a modified subcostal transthoracic view might be helpful. DESIGN: A prospective observational study...

Fei Fei Gong, Duncan J Campbell, David L Prior
Heart failure (HF) continues to grow as a cause of morbidity and mortality in our community and presents a significant public health problem, predominantly in individuals ≥65 years of age. Early intervention in asymptomatic HF subjects (Stage A/B) at risk of progression to symptomatic HF (Stage C/D) may provide an opportunity to halt this epidemic. The ability of cardiac imaging to assess cardiac structure and function permits early identification of those at increased risk of developing symptomatic HF. Systolic, diastolic, and structural left ventricular parameters each predict symptomatic HF, but no single parameter has sufficient sensitivity for screening to identify individuals with Stage A/B HF who are at increased risk of disease progression...

RATIONALE: We have hypothesized that post-infarction cardiac remodeling can be influenced by shifts in the balance between intracellular mediators of "pathologic" and "physiologic" hypertrophy. Although alpha1 adrenergic receptors (alpha1-ARs) mediate pro-adaptive hypertrophy during pressure overload, little is known about their role or downstream mediators after myocardial infarction. METHODS: We performed loss-of-function experiments via coronary ligation in alpha1A-AR knockout (AKO) mice...

AIMS: Heart failure with preserved ejection fraction (HFpEF) remains a common condition with no pharmacological treatment. Physical activity (PA) improves symptoms and quality of life (QoL), but no clear recommendations exist on PA in HFpEF patients. We investigated the association of PA (amount/intensity) on clinical phenotype in HFpEF. METHODS AND RESULTS: The Aldosterone in Diastolic Heart Failure trial investigated spironolactone vs. placebo in stable HFpEF patients...

Iron-overload cardiomyopathy is prevalent on a worldwide basis and is a major co-morbidity in patients with genetic hemochromatosis and secondary iron overload. Therapies are limited in part due to lack of a valid pre-clinical model, which recapitulates advanced iron-overload cardiomyopathy. Male hemojuvelin knockout (HJVKO) mice, which lack hemojuvelin (HJV), a bone morphogenetic co-receptor protein required for hepcidin expression and systemic iron homeostasis, were fed a high iron diet starting at 4 weeks of age for a duration of 1 year...

OBJECTIVE: To describe the technique and review the utility of bedside lung ultrasound in acute care. SUMMARY: Lung ultrasound is a useful point-of-care investigation in acute care, especially in patients with dyspnoea or haemodynamic instability. Although normal lung parenchyma is not accessible to ultrasound, distinctive artefacts arising from parietal and visceral pleura indirectly imply the presence of normal lung. As aeration of lung tissue reduces with disease process, visual assessment of several pathologic entities by ultrasound becomes possible...

Hemodynamic monitoring is essential for prompt and effective interventions in intensive care unit patients. We developed a custom-made transthoracic echocardiography transducer holder consisting of transducer holder and skin patch attachment. This holder allowed continuous transthoracic echocardiography monitoring in 5 adult patients with circulatory failure due to shock, and 6 pediatric patients after successful percutaneous closure of a ventricular septal defect. One case of an unexpected hemopericardium was promptly diagnosed and pericardiocentesis was performed, and 1 patient required extracorporeal membrane oxygenation support...

Current evidence suggests that exercise training is beneficial in pulmonary arterial hypertension (PAH). Unfortunately, the standard supervised, hospital-based programs limit patient accessibility to this important intervention. Our proof-of-concept study aimed to provide insight into the usefulness of a prescribed walking regimen along with arginine supplementation to improve outcomes for patients with PAH. Twelve PAH patients (all women) in New York Heart Association (NYHA) functional class (FC) II (n = 7) or III (n = 5) and in stable condition for ≥ 3 months were enrolled...

Bioprosthesis thrombosis after transcatheter aortic valve replacement (TAVR) raised concerns about further clinical events. We report the case of a patient who suffered acute myocardial infarction (AMI) after TAVR for 3 years. Thrombosis was confirmed in the right coronary sinus of Valsalva by transthoracic echocardiography. Coronary angiography demonstrated the ostium of the right coronary artery was occluded. As an attempt to perform percutaneous coronary intervention (PCI) was unsuccessful, long-term therapeutic anticoagulation with warfarin was undertaken...
