This paper proposes a robotic Transesophageal Echocardiography (TOE) system concept for Catheterization Laboratories. Cardiovascular disease causes one third of all global mortality. TOE is utilized to assess cardiovascular structures and monitor cardiac function during diagnostic procedures and catheter-based structural interventions. However, the operation of TOE underlies various conditions that may cause a negative impact on performance, the health of the cardiac sonographer and patient safety. These factors have been conflated and evince the potential of robot-assisted TOE...

BACKGROUND: Infective endocarditis (IE) is uncommon in childhood. Its associated epidemiological characteristics in patients with congenital heart disease (CHD) remain unclear. METHODS: The study population included children born in Taiwan during the years 1997 to 2005 who were diagnosed as having CHD before 3years of age. All children were followed up until the end year of 2010, the diagnosis of infective endocarditis, or death. The demographic characteristics of patients with and without IE, the invasive procedures performed during 6months before the index date, the prophylactic antibiotics related to dental procedures, and in-hospital mortality were collected...

It is acknowledged that contrast-induced nephropathy (CIN) is a common cause of acute renal insufficiency after cardiac catheterization and affects mortality and morbidity. To date, it is unknown whether oral N-acetylcysteine (NAC) is able to prevent contrast-induced nephropathy (CIN) in patients undergoing coronary angioplasty. A meta-analysis of randomized controlled trials was performed to assess the effects of NAC in the prevention of CIN in patients following coronary angioplasty. A total of 19 studies published prior to January 2015 that investigated the efficacy of oral NAC for the prevention of CIN were collected from Medline, Cochrane and Embase databases and conference proceedings from cardiology and nephrology meetings...

The goal of this study was to confirm the vasopressor and cardiac effects of POTENAY(®) INJETÁVEL (POT), a mephentermine-based product, given to cattle with induced vascular/cardiac depression. Ten healthy Holstein cattle (206 ± 13 kg) followed a randomized-complete-block design (RCBD) utilizing crossover study design. Each animal randomly received (1 ml/25 kg, IM) of either POT (n = 10) or volume-matched placebo control (0.9%NaCl, CP, n = 10). A subset of animals (n = 5) received POT first (day 0) while the remaining (n = 5) received CP; after a six-day washout period, cattle received the opposite compound...

BACKGROUND: Despite advances in ST-elevation myocardial infarction (STEMI) systems of care over the last decade, studies have shown no improvement in risk-adjusted mortality. It has been hypothesized that the population presenting to the catheterization lab has become sicker over time, in ways not accurately captured by current mortality models. OBJECTIVE: The objective of this study was to examine changes in the clinical characteristics and in-hospital case fatality rate of the STEMI population treated with early percutaneous coronary intervention (PCI)...

L A Cope
Ventricular bands, also designated as 'false tendons', are described as single or multiple strands that cross the ventricles and have no connection to valvular cusps. Previous work indicates these strands are present in the ventricles of humans and some animal hearts and not always associated with cardiac pathologies. Despite these previous studies, the published literature is limited in documenting the morphology of these strands and incidence in animals. In this study, examination of 89 hearts showed six types of ventricular bands in the right ventricle of the domestic dog...

Terumoto Koike, Masanori Tsuchida
For general thoracic surgeons, perioperative management for prevention of cardiac complications is important because patients undergoing general thoracic surgery often have risk factors for cardiac disease. Sever cardiac failure should be detected and treated prior to surgery, and coronary artery may be examined in patients with risk factors for ischemic heart disease. Pulmonary resection sometimes causes right-sided heart failure due to reducing pulmonary vascular bed. In high-risk patients for rightsided heart failure, pulmonary artery pressure monitoring by right heart catheterization should be considered in addition to blood pressure and central venous pressure monitoring, and precise fluid management is required...

A 66-year-old woman was referred to our hospital with dyspnea. Right-sided congestive pleural effusion of an unknown etiology was detected and she was diagnosed with constrictive pericarditis. Pericardiectomy was performed via median sternotomy under extracorporeal circulation because severe adhesion was observed. However, hemodynamics did not improve after pericardial resection because of thickend epicardium in front of the right ventricle. Hence, the waffle procedure was additionally performed on the anterior surface of the right ventricle after coming-off the extracorporeal circulation...
