BACKGROUND: Estimated continuous cardiac output (esCCOTM) based on pulse wave transit time is one of alternative non-invasive CO measurement techniques. METHODS: Randomized study included 23 scheduled patients operated upon due to cardiovascular diseases. Cardiac index (CI) was measured Comparative analyses of esCCO and others CO measurement methods used intraoperative was carried out. In the first group (n = 9) esCCO was compared with transpulmonary thermodilution (PiCCO-plus); in the second group (n = 8) - with pulmonary artery thermodilution; in the third group (n = 6) - with transoesophageal echocardiography (velocity-time integral)...

Cardiac tumors are relatively rare, with primary hemangiomas being a particularly rare benign neoplasm. Herein, we report a case of a symptomatic cardiac tumor detected via echocardiography in an 82-year-old woman. Although we performed advanced imaging examinations for her heart, we could not diagnose the tumor before surgery. Eventually, a tumor involving the left atrial roof was detected, and it was completely resected to relieve her symptoms and establish a precise diagnosis. Histopathological examination indicated a cardiac cavernous hemangioma...

INTRODUCTION: Various anomalies in the development of the great thoracic veins of the embryo can be incidentally discovered in the normal adult. Duplication of superior vena cava (SVC) is a rare abnormality, but the most common thoracic venous congenital anomaly. Case reports-methods: We present two cases in the intensive care unit of our hospital, of asymptomatic patients who underwent an uneventful central line placement in the left subclavian vein. The track of the catheter, as shown in the X-ray, was misplaced to the left of the aorta and further investigation with computed tomography angiography confirmed a persistent left SVC...

Transesophageal echocardiography (TEE) is the gold standard imaging study used in the diagnosis of infective endocarditis (IE). Computed tomography angiography (CTA) has undergone rapid advancement as a cardiac imaging technique and has previously shown promise in small non-randomized studies for evaluation of IE. We hypothesized that cardiac CTA would perform similarly to TEE in the detection of endocarditic lesions and that there would be no difference in clinical outcomes whether the coronary arteries were evaluated by CTA or invasive coronary angiography (ICA)...

Left ventricular noncompaction cardiomyopathy (LVNC) is characterized by compact and trabecular layers of the left ventricular myocardium. This cardiomyopathy may occur with congenital heart disease (CHD). Single cases document co-occurrence of LVNC and heterotaxy, but no data exist regarding the prevalence of this association. This study sought to determine whether a non-random association of LVNC and heterotaxy exists by evaluating the prevalence of LVNC in patients with heterotaxy. In a retrospective review of the Indiana Network for Patient Care, we identified 172 patients with heterotaxy (69 male, 103 female)...

Intraoperative use of transesophageal echocardiography (TEE) has become commonplace in high-risk noncardiac surgeries but the balance of benefits and harms remains unclear. This systematic review investigated the comparative effectiveness and harms of intraoperative TEE in noncardiac surgery. We searched Ovid MEDLINE, PubMed, EMBASE, and the Cochrane Library from 1946 to March 2017. Two reviewers independently screened the literature for eligibility. Studies were assessed for the risk of selection bias, confounding, measurement bias, and reporting bias...

Angiosarcomas of the uterine is a malignant and poor prognostic tumor and can either be a primary sarcoma or arising secondary to radiotherapy of a more complex tumor. Primary uterine angiosarcomas are exceptional and probably arise from embryonic vascular remnants, teratoma or from the rich uterine vasculature. We reported a rare case of primary angiosarcoma of uterine that at the time of diagnosis presented with sign and symptom of local and distant metastasis. The patient presented with dyspnea, chest pain, and history of vaginal bleeding and pelvic pain...

PURPOSE: Quercetin, a flavonoid, has been reported to ameliorate cardiovascular diseases, such as cardiac hypertrophy. However, the mechanism is not completely understood. In this study, a mechanism related to proteasome-glycogen synthesis kinase 3 (GSK-3) was elucidated in rats and primary neonatal cardiomyocytes. METHODS: Rats were subjected to sham or constriction of abdominal aorta surgery groups and treated with or without quercetin for 8 weeks. Angiotensin II (Ang II)-induced primary cardiomyocytes were cultured with quercetin treatment or not for 48 h...

BACKGROUND: Heart failure is a serious event in patients with transposition of the great arteries (D-TGA) after atrial redirection surgery. We aimed to determine the association between myocardial fibrosis and systolic and diastolic systemic right ventricle (sRV) dysfunction. METHODS: Diastolic and systolic function of sRV was prospectively assessed using echocardiography and cardiac magnetic resonance imaging (CMR) in 48 patients with atrially switched D-TGA and 26 healthy subjects...

Masses in and near the interatrial septum may be either benign or malignant. The most common mass near the interatrial septum is lipomatous atrial septal hypertrophy (LASH). LASH can be present in patients with intracardiac malignancies, myxomas, lipomas, or other cardiac masses. It is important to recognize the transesophageal echocardiography (TEE) characteristics of these pathologies to arrive at an accurate diagnosis with an appropriate plan for intraoperative resection. At the authors' institution, patients have been referred for surgery due to a finding of significant LASH masquerading as a left atrial myxoma...

BACKGROUND: Acute kidney injury (AKI) is a common serious complication following cardiac surgery. Doppler-determined renal resistive index (RRI) is a promising early AKI biomarker in this population. However, the relationship between aortic valve pathology (insufficiency and/or stenosis) and RRI is unknown. This study aimed to investigate RRI variability related to aortic valve pathology. METHODS: In a retrospective review of cardiac surgery patients, RRI and aortic valve pathology were assessed prior to cardiopulmonary bypass using transesophageal echocardiography...

Ebstein anomaly is a congenital disorder of right ventricular myocardial development, which affects the tricuspid valve in addition to the right ventricular myocardium. Cardiac imaging by transthoracic echocardiography and cardiac magnetic resonance imaging are the key modalities used to assess timing and type of surgery. In this article, we review the current standards of echocardiographic and magnetic resonance imaging in Ebstein anomaly.

This article outlines the diagnosis and management of commonly occurring valvular heart diseases for the primary care provider. Basic understanding of pathologic murmurs is important for appropriate referral. Echocardiography is the gold standard for diagnosis and severity grading. Patients with progressive valvular heart disease should be followed annually by cardiology and imaging should be performed based on the severity of valvular dysfunction. Surgery or intervention is recommended only when symptoms dictate or when changes in left ventricular function occur...

The patient was a 70-year-old woman who was diagnosed with obstructive transverse colon cancer suspected of invading the abdominal wall by abdominal CT imaging. Since the preoperative electrocardiogram showed an ischemic change, echocardiography and coronary angiography were performed. We diagnosed chronic heart failure and angina pectoris because echocardiography showed low cardiac function(left ventricular ejection fraction; LVEF 37%)and coronary angiography indicated triple-vessel disease. We firstly performed coronary artery bypass graft surgery following self-expanding metallic stent placement as a bridge to surgery(BTS), because we judged this patient as a perioperative high-risk case...
