murs was evaluated in 36 patients and the results compared with the effects of amyl nitrite and phenylephrine. The isometric handgrip exercise produced immediate, reproducible, and significant increases in heart rate and blood pressure. It also increased the intensity of murmurs due to aortic and mitral regurgitation and mitral stenosis and attenuated the murmurs of left ventricular outflow tra...

Aortic pseudoaneurysm after cardiac surgery is a rare entity, but it is potentially fatal due to its clinical course along with higher morbidity and mortality rates. Instead of open surgical repair, percutaneous procedures have been introduced as other options for managing an aortic pseudoaneurysm. In this case report, we describe transesophageal echocardiography guidance for successful percuta...

OBJECTIVE Early detection of changes in cardiovascular echocardiographic systolic parameters and their comparison with normotensives women. METHODS This was a hospital-based prospective case-control study carried out in Department of Obstetrics and Gynaecology in S.M.S Medical College, Jaipur, during the period from February 2013 to December 2014. In total, 100 women were enrolled in the stud...

In the present study, we examined the influence of preload augmentation via passive leg elevation (PLE) on synthesized aortic blood pressure, aortic augmentation index (AIx), and aortic capacitance (a reflection of aortic reservoir function). Central and peripheral hemodynamics were measured via tonometry with a generalized transfer function in 14 young, healthy men (age = 24 yr). Aortic blood ...

Decomposing the Ins and Outs of Cyclical Unemployment This paper analyzes the contribution of the socioeconomic and demographic composition of the pool of employed and unemployed individuals to the dynamics of the labor market in different phases of the business cycle. Using individual level data from the Current Population Survey (CPS), we decompose differences in employment status transition ...

In Earth's environment, the observed polar outflow rate for O(+) ions, the main source of oxygen above gravitational escape energy, corresponds to the loss of approximately 18% of the present-day atmospheric oxygen over 3 billion years. However, part of this apparent loss can actually be returned to the atmosphere. Examining loss rates of four escape routes with high-altitude spacecraft observa...

Protein separation through hollow fiber flow field-flow fractionation (HF FlFFF) at microflow rate regime was successfully achieved by employing a microbore hollow fiber. In most of the flow field-flow fractionation (FlFFF) techniques applied to the separation of proteins, including hollow fiber FlFFF (HF FlFFF), an outflow rate leading to a detector has typically been a few tenths of a millili...

BACKGROUND Left ventricular outflow tract (LVOT) obstruction and paravalvular leak (PVL) are relatively uncommon, but are serious complications of prosthetic valve replacement. CASE PRESENTATION We present a case that displays the unique therapeutic challenges of treating a patient who developed both LVOT obstruction and mitral PVL after undergoing surgical aortic and mitral valve replacement...

BACKGROUND During cardiac resynchronization therapy (CRT), cardiac performance is dependent on an optimized atrioventricular delay (AVD). However, the optimal AVD at different heart rates has not been defined yet during CRT. METHOD The effects of an increase in heart rate by pacing or physical exercise on optimal AVD were studied in 36 patients with biventricular pacemakers/defibrillators. Th...

BACKGROUND Improvement in the left ventricular outflow tract (LVOT) gradient has been used as a means of assessing response to therapy in patients with hypertrophic obstructive cardiomyopathy (HOCM). To our knowledge, no data exist regarding the spontaneous day-to-day variability of the LVOT gradient in patients with HOCM. Defining the magnitude of such variability is critical to properly under...
