Mechanical prostheses induce artifacts that decrease the accuracy of conventional transthoracic echocardiographic imaging for the detection and quantitation of periprosthetic mitral regurgitation. In 15 patients undergoing transthoracic echocardiography, injection of sonicated albumin significantly
A group of 23 consecutive patients with isolated mitral regurgitation confirmed by angiography, 8 of whom had normal and 15 abnormal coronary arteriographies, were compared with a control group of 27 subjects without valvular heart disease (normal coronary arteriography in 7 cases, abnormal coronary
Mitral stenosis (MS) and mitral regurgitation (MR) are the most frequent conditions that cause a dilation and dysfunction of the left atrial appendage (LAA). Despite similarly dilated LAA in patients with MS and MR, the incidence of LAA thrombi and the risk of thromboembolism is different between
Evidence suggesting that mitral regurgitation (MR) may be induced by appetite suppressant medications heightens the importance of understanding the prevalence and correlates of MR, especially its relation to obesity, in population-based samples. MR was assessed by color Doppler echocardiography in
OBJECTIVE
The objective of this study was to evaluate the effect of a transpulmonary contrast agent on Doppler flow signals in the left heart chambers.
BACKGROUND
Echo contrast agents are good ultrasound reflectors and could be used as Doppler signal enhancers. Sonicated albumin microbubbles are
Tricuspid regurgitation refers to a systolic leak of blood between the right ventricle and right atrium, across the tricuspid valve. Doppler echocardiographic examination of large numbers of normal individuals has shown that trivial tricuspid regurgitation is extremely common. Measurement of the
INTRODUCTION Although there are several known risk factors of cardiovascular diseases (CVDs), the search for new factors continues. In recent years, clinical trials have reported vitamin D and other calcium (Ca) and phosphate (P) metabolism disorders as potential new cardiovascular risk factors,
1. Unlike in normal rabbits, pulmonary rapidly adapting receptors (RARs) in rabbits with chronic mitral regurgitation (MR) do not respond to small changes in extravascular fluid (EVF) volume in major airways. The present study examined the effect of shrinking the EVF volume in rabbits with chronic
Application of a mathematical model of microhemocirculation enabled one to assess quantitatively the magnitude of transcapillary albumin metabolism and total hydraulic resistance of metabolic vessels, as well as the effect of geometric, biophysical and hemodynamic parameters on transport
Despite numerous studies on extravascular lung water (EVLW) in patients undergoing coronary artery bypass surgery, few data are available on the perioperative time course of EVLW in patients undergoing mitral valve replacement for mitral valve insufficiency (MVI). We have investigated 26 patients
OBJECTIVE
Cardiopulmonary bypass is associated with changes of intra- and extravascular volume status often resulting in cardiopulmonary dysfunction. The purpose of this prospective double-blind study was to evaluate the influence of different priming solutions of the extracorporeal circuit on
A 58-year-old female was diagnosed as mitral regurgitation and tricuspid regurgitation, combined with liver cirrhosis (T. Bil 2.3 mg/dl, ICG-R 37%) and pancytopenia (Hb 9.4 g/dl, WBC 3,000, Plt 56,000). She underwent mitral and tricuspid annular plications. After extracorporeal circulation, the
A 27-year-old man who was diagnosed with arrhythmogenic right ventricular dysplasia (ARVD) underwent the total right ventricular (RV) exclusion procedure: the RV free wall was resected and an extracardiac total cavopulmonary connection (TCPC) was created using a 24-mm-diameter
BACKGROUND
Cardiac disease is the main cause of death in hemodialysis patients. In hemodialysis patients cardiovascular complications are great clinical challenge, and function, shape and left ventricle abnormalities are present in 70 - 80 percent of dialysis patients. Changes in heart function
BACKGROUND
The pathogenesis of posterior papillary muscle dysfunction is poorly understood. We hypothesized that papillary muscle perfusion pattern may explain the higher prevalence of posterior papillary muscle dysfunction after myocardial infarction.
RESULTS
Twenty patients were monitored by
