Metabolic syndrome in subjects with white-coat hypertension: impact on left ventricular structure and function

2007

Some reports have suggested that white-coat hypertension (WCH) is associated with some features of the metabolic syndrome (MetS). These metabolic disturbances, instead of WCH per se, may potentially explain the greater extent of end-organ damage sometimes observed in WCH subjects (WCHs) when compared to normotensive individuals (NTs). The aim of the present cross-sectional study was to compare left ventricular (LV) structure and function in three groups of subjects: WCHs with MetS, WCHs without MetS and NTs. A total of 145 WCHs, 35% of whom had MetS, were enrolled. As controls, 35 NTs were also studied. In all subjects, routine blood chemistry, echocardiographic examination and 24-h ambulat…

Large left ventricular metastatis in patient with liposarcoma.

2014

Abstract Metastasis to the heart and pericardium are rare. We present a 44-year-old male with pleural dedifferentiated liposarcoma and multiple metastases, with no previous cardiological history and/or cardiac symptoms. A transthoracic echocardiogram during the advanced stage of disease showed a lobulated, large and mobile mass, with homogeneous echogenicity, attached to the basal posterior wall of the left ventricle via a broad base and with intracavitary growth. This mass extends to inferolateral and inferoseptal wall of the left ventricle.

Regurgitant flow in apparently normal valve prostheses: improved detection and semiquantitative analysis by transesophageal two-dimensional color-cod…

1990

In 128 patients with apparently normally functioning prosthetic valves ( n = 136) in the aortic position ( n = 79) and the mitral position ( n = 57), the prevalence of transprosthetic regurgitant flow was studied by use of transthoracic and transesophageal two-dimensional color-coded Doppler echocardiography. With the transthoracic approach, regurgitant flow was detected in early systole or diastole for 28% of the mitral prostheses and for 29% of the aortic prostheses. With transesophageal color-coded Doppler echocardiography, regurgitant jets were visualized for 95% of the mitral prostheses and for 44% of the aortic prostheses. In 40% of the Bjork-Shiley prostheses and 88% of the St. Jude …

Comparison between doppler-echocardiography and uncalibrated pulse contour method for cardiac output measurement. a multicenter observational study

2016

Objectives: Echocardiography and pulse contour methods allow, respectively, noninvasive and less invasive cardiac output estimation. The aim of the present study was to compare Doppler echocardiography with the pulse contour method MostCare for cardiac output estimation in a large and nonselected critically ill population. Design: A prospective multicenter observational comparison study. Setting: The study was conducted in 15 European medicosurgical ICUs. Patients: We assessed cardiac output in 400 patients in whom an echocardiographic evaluation was performed as a routine need or for cardiocirculatory assessment. Interventions: None. Measurements and Main Results: One echocardiographic car…

Congenital mitral regurgitation caused by a perforation in the anterior leaflet: Perioperative evaluation by color-coded Doppler echocardiography

1990

Color-coded two-dimensional (2D) echocardiography confirmed the presence of severe congenital mitral regurgitation in an 8-month-old infant. Intraoperative inspection revealed an isolated perforation in the anterior leaflet.

Methods to investigate coronary microvascular function in clinical practice.

2012

A growing amount of data is increasingly showing the relevance of coronary microvascular dysfunction (CMVD) in several clinical contexts. This article reviews techniques and clinical investigations of the main noninvasive and invasive methods proposed to study coronary microcirculation and to identify CMVD in the presence of normal coronary arteries, also trying to provide indications for their application in clinical practice.

Background: Detecting paroxysmal atrial fibrillation (PAF) in patients with cerebral ischemia is challenging. Frequent premature atrial complexes (PAC/h) and the longest supraventricular run on 24-h-Holter (SV-run24 h), summarised as excessive supraventricular ectopic activity (ESVEA), may help selecting patients for extended ECG-monitoring, especially in combination with echocardiographic marker LAVI/a’ (left atrial volume index/late diastolic tissue Doppler velocity). Methods: Retrospective analysis from the prospective monocentric observational trial Find-AF (ISRCTN-46104198). Patients
