Uncontrolled pulmonary hypertension may cause worse outcomes after transcatheter aortic valve replacement (TAVR), while hemodynamic monitoring is desirable for risk control. Pulmonary artery pressure (PAP) readings obtained by intracardiac Doppler echocardiography were evaluated.
This article was published in the following journal.
Doppler echocardiography is a well-recognized technique for the noninvasive evaluation of pulmonary artery pressure; however, little information is available concerning patients receiving mechanical v...
Knowledge of the left ventricular pressures throughout the cardiac cycle is of considerable assistance in managing a haemodynamically unstable patient. Invasive pressure measurement is the only accura...
Pulmonary hypertension (PH) is an ominous complication in systemic sclerosis patients (SSc) and echocardiography is a screening tool for its detection. The goal of this study was to assess the reliabi...
Anomalous origin of coronary artery from pulmonary artery (ALCAPA) is a rare coronary anomaly usually presenting in the first year of life. Adult presentation suggests a wide range of differential dia...
Background The Doppler effect has allowed the characterization of several vessels in maternal-fetal circulation that have been used for practical purposes. Our review of the literature showed a paucit...
This study will evaluate the efficacy of the Foresight Intracardiac Echocardiography system ,with improved image quality, in guiding trans-septal punctures during atrial fibrillation ablat...
The fundamental hypothesis of this project is that real-time intracardiac pressures can be monitored and quantified noninvasively in humans using a novel contrast-enhanced ultrasound techn...
Non-invasive evaluation of patients with stable angina and unstable coronary syndromes with transthoracic Doppler echocardiography to evaluate presence of significant coronary stenoses. Bl...
In this study, the investigators sought to determine whether an acoustic cardiographic assessment of heart function is equivalent to Doppler-echocardiography in patients who are treated wi...
The investigators aim to correlate noninvasive pulmonary artery systolic pressure (PASP) measurements obtained with and without echocardiographic contrast (Optison) during transthoracic ec...
Measurement of intracardiac blood flow using an M-mode and/or two-dimensional (2-D) echocardiogram while simultaneously recording the spectrum of the audible Doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells.
Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.
Echocardiography applying the Doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return.
The pressure within a CARDIAC VENTRICLE. Ventricular pressure waveforms can be measured in the beating heart by catheterization or estimated using imaging techniques (e.g., DOPPLER ECHOCARDIOGRAPHY). The information is useful in evaluating the function of the MYOCARDIUM; CARDIAC VALVES; and PERICARDIUM, particularly with simultaneous measurement of other (e.g., aortic or atrial) pressures.
Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
Cardiology is a specialty of internal medicine. Cardiac electrophysiology : Study of the electrical properties and conduction diseases of the heart. Echocardiography : The use of ultrasound to study the mechanical function/physics of the h...
