A 5-month-old infant, referred to our institution for percutaneous arterial duct (AD) embolization, showed multiple huge pulmonary arteriovenous malformations (PAVMs) associated with a small AD and several tiny systemic-to-pulmonary collaterals. This anatomic arrangement was a possible cause of lack of cyanosis and disproportionately higher hemodynamic relevance of the ductal shunt. The PAVMs became pathophysiologically evident immediately after the closure of AD and systemic to pulmonary artery collaterals and presented clinically with a life-threatening cyanosis...

BACKGROUND: Surgical residency training programs in the United States are modeled on the principle of graduated responsibility. Residents are given greater responsibility and autonomy in the operating room and during perioperative care as they gain surgical skills and progress through their training. The impact of this method of surgical training on patient outcomes remains unknown. The purpose of this study is to compare early patient morbidity and mortality after bariatric surgery in cases with and without resident participation using the American College of Surgeons National Surgical Quality Improvement Program database...

Rationale: More than 50% of patients with heart failure have preserved ejection fraction characterized by diastolic dysfunction. The prevalance of diastolic dysfunction is higher in females and associates with multiple comorbidities such as hypertension (HT), obesity, hypercholesterolemia (HC) and diabetes mellitus (DM), although its pathophysiology remains incompletely understood. It has been proposed that the co-morbidities induce systemic inflammation, cardiac microvascular dysfunction and oxidative stress, leading to myocardial fibrosis, myocyte stiffening and ultimately, diastolic dysfunction...

Ischemic strokes may be associated with atrial fibrillation (AF). AF detection is critical in ischemic stroke survivors, often recommending a switch from antiplatelet therapy to oral anticoagulants for secondary prevention. Areas covered: Cardiac implantable electronic devices (CIED) with their long-term recording capability allows to document AF and to quantify the arrhythmia burden. Recent series in pacemaker and implantable cardioverter-defibrillator (ICD) recipients with no prior stroke showed that short episodes of AF increased stroke risk compared with those without AF recorded...

OBJECTIVE: We aimed to evaluate the yield of extensive etiologic workup in lacunar stroke patients. BACKGROUND: As lacunar strokes are infrequently caused by thromboembolism, the clinical relevance of extensive workup for thromboembolic sources is questioned. METHODS: Among consecutive stroke admissions to a single center over 3 years, the 100 cases initially classified as lacunar stroke and a sample of 100 cases classified as non-lacunar ischemic strokes were studied...

Neurologic deficit subsequent to cardiac surgery remains a cause of postoperative morbidity and mortality. Although myriad risk factors for postoperative cognitive decline have been identified, their individual influence remains undefined. Although less emphasis is now placed on the heart lung machine as the major source of postoperative cognitive decline, the conduct of cardiopulmonary bypass and, in particular, the management of the bypass circuit remain key to patient safety. We present a case of inadvertent intraoperative exsanguination of a patient following open heart surgery for implantation of a left ventricular assist device...

Acute pulmonary embolism (APE) is a serious disease which is life-threatening. Since it is crucial for APE patients to assess the changes of cardiac function safely and timely, the imaging research of cardiac morphology and function is becoming more and more important. The correlation of computed tomography (CT) measured cardiac parameters and pulmonary obstruction index (POI) was analyzed to discuss the morphological changes of the heart of APE patients in order to provide a new method to evaluate cardiac functions accurately and effectively...

REVIEW
Burke A Cunha, Bertamaria Dieguez, Alena Varantsova
Culture negative endocarditis (CNE) is a common concern in patients with fever, heart murmur, cardiac vegetation, and negative blood cultures. The diagnosis of CNE is not based only on negative blood cultures and a cardiac vegetation. The clinical definition of CNE is based on negative blood cultures plus the findings of culture positive infective endocarditis (IE), e.g., fever, cardiac vegetation, splenomegaly, peripheral manifestations. Because embolic splenic infarcts may occur with culture positive IE, some may assume that splenic infarcts are a sign of CNE...

Cardiac tamponade caused by perforation of the cardiac wall is a rare complication related to central venous catheter (CVC) placement. A 71-year-old female with a previous history of moderate aortic stenosis and kidney transplantation was admitted to hospital due to global heart failure and worsening of allograft function. Intensified hemodialysis was commenced through a CVC placed in the right subclavian vein. Chest radiography revealed catheter tip in the right atrium and no signs of pneumothorax. Thorough diagnostics outruled immediate life-threatening conditions, such as myocardial infarction and pulmonary embolism...

BACKGROUND: Atrial fibrillation (AF) affects 1.5-2% of the population and is associated with a five-fold increased lifetime risk of stroke [1]. The left atrial appendage (LAA) is the source of embolic strokes in up to 90% of patients with non-valvular AF with clots in the left atrium [2]. METHODS: We reviewed the clinical notes and echocardiographic findings of 20 patients who underwent open cardiac surgery in which concurrent AtriClip (Atricure Inc, Westchester, Ohio, USA) device insertion was attempted at our institution from July 2013 to February 2015...

Prior to the Fontan procedure, patients with single ventricle physiology with Glenn shunt are typically referred for cardiac catheterization to assess hemodynamics and potentially provide interventional measures. Currently, echocardiography provides detailed information which together with other non-invasive imaging such as CT scan and MRI may obviate the need for routine cardiac catheterization prior to the Fontan procedure. In this study, we examine the findings in cardiac catheterization in this population to determine: (a) the accuracy of echocardiography in providing adequate information prior to the Fontan procedure, particularly in identifying those in need of per-catheter intervention, and (b) the percentage of patients requiring interventional procedures during cardiac catheterization...
