Article Synopsis
- The study focuses on adults with congenital heart disease (ACHD), who often suffer from heart failure (HF) due to past surgeries and require better treatment data to improve their care.
- Researchers will collect data from a multi-country register, the ARTORIA-R, identifying ACHD patients listed for heart transplantation from 1989-2020, using both retrospective and prospective methods.
- The goal is to track outcomes like clinical worsening, death on the waiting list, and overall mortality after transplantation to enhance understanding and management of advanced heart failure in this population.
Objectives: The aim of the present study was to assess the validity and trending ability of the bioreactance method in estimating cardiac output at rest and in response to stress in advanced heart failure patients and heart transplant candidates.
Design: This was a prospective single-center study.
Setting: This study was conducted at the heart transplant center at the Freeman Hospital, Newcastle upon Tyne, UK.
Objective: The present study assessed agreement between resting cardiac output estimated by inert gas rebreathing (IGR) and thermodilution methods in patients with heart failure and those implanted with a left ventricular assist device (LVAD).
Methods And Results: Hemodynamic measurements were obtained in 42 patients, 22 with chronic heart failure and 20 with implanted continuous flow LVAD (34 males, aged 50 ± 11 years). Measurements were performed at rest using thermodilution and IGR methods.
We sought to determine hemodynamic mechanisms of exercise intolerance in a group of patients with the HeartWare ventricular assist device (VAD) compared to a group of heart failure patients. Twenty VAD and 22 heart failure patients underwent symptom-limited active straight leg raising exercise during right heart catheterization with thermodilution (TD), and upright cycling cardiopulmonary stress testing with cardiac output measurement by inert gas rebreathing (IGR) method. The TD and IGR exercise cardiac indexes were higher in VAD compared with heart failure group (both P < 0.
