A Comparison of Third-Generation Semi-Invasive Arterial Waveform Analysis with Thermodilution in Patients Undergoing Coronary Surgery [PDF]

The Scientific World Journal, 2012
Uncalibrated semi-invasive continous monitoring of cardiac index (CI) has recently gained increasing interest. The aim of the present study was to compare the accuracy of CI determination based on arterial waveform analysis with transpulmonary ...

Interference of Continuous Renal Replacement Therapy on PiCCO Hemodynamic Monitoring: A Case Report. [PDF]

Clin Case Rep
ABSTRACT The proximity of the central venous and dialysis catheters during continuous renal replacement therapy can interfere with Pulse Index Continuous Cardiac Output hemodynamic measurements. Adjusting catheter placement or temporarily pausing continuous renal replacement therapy during measurement is essential to ensure accurate hemodynamic ...

Impact of Procedural Differences on Bolus Thermodilution Method for Assessment of Coronary Microvascular Dysfunction. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Background The thermodilution technique, employing bolus injections to measure coronary flow reserve (CFR) and the index of microcirculatory resistance (IMR), is widely used to assess coronary microvascular function. However, the potential influence of catheter size and operator differences on these measurements has not been systematically ...

Noninvasive Assessment of Cardiac Output: Accuracy and Precision of the Closed‐Circuit Acetylene Rebreathing Technique for Cardiac Output Measurement

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Accurate assessment of cardiac output is critical to the diagnosis and management of various cardiac disease states; however, clinical standards of direct Fick and thermodilution are invasive.

Could Impedance Cardiography be a Non-Invasive Alternative Method of Measuring Cardiac Output in Patients with Pulmonary Hypertension?

Anatolian Journal of Cardiology, 2023
Background: Pulmonary hypertension guidelines recommend invasive right heart catheterization for diagnosis and clinical follow-up. Our aim was to compare non-invasive impedance cardiography with invasive techniques for cardiac index measurements and ...

Continuous Versus Bolus Thermodilution‐Derived Coronary Flow Reserve and Microvascular Resistance Reserve and Their Association With Angina and Quality of Life in Patients With Angina and Nonobstructive Coronaries: A Head‐to‐Head Comparison

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Coronary flow reserve (CFR) and microvascular resistance reserve (MRR) are physiological parameters to assess coronary microvascular dysfunction. CFR and MRR can be assessed using bolus or continuous thermodilution, and the correlation between

Microcirculatory Function in Nonhypertrophic and Hypertrophic Myocardium in Patients With Aortic Valve Stenosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Left ventricular hypertrophy (LVH) has often been supposed to be associated with abnormal myocardial blood flow and resistance. The aim of this study was to evaluate and quantify the physiological and pathological changes in myocardial blood ...

Goal-directed therapy in intraoperative fluid and hemodynamic management. [PDF]

, 2013
Intraoperative fluid management is pivotal to the outcome and success of surgery, especially in high-risk procedures. Empirical formula and invasive static monitoring have been traditionally used to guide intraoperative fluid management and assess volume
