Strategies for low-molecular-weight heparin management in pregnant women with mechanical prosthetic heart valves: A nationwide survey of Dutch practice.

Background: In this study we investigated current Dutch practice of low molecular weight heparin (LMWH) treatment in pregnant women with mechanical prosthetic heart valves (MPHV) in order to evaluate how management can be optimized.

Methods: Between December 2020 and February 2021, we conducted a survey among Dutch congenital cardiologists of tertiary centers in the Netherlands. We collected and analyzed written, unstructured, open questionnaires that were send to all 8 specialized pregnancy heart teams.

Quality of Life Among Patients With Congenital Heart Disease After Valve Replacement.

Most studies concerning valve replacement in congenital heart disease (CHD) focus on surgical morbidity and mortality. However, with the increased life expectancy of these patients, the focus shifts to quality of life (QOL). The aim of this study was to report and compare the QOL of CHD patients after valve replacement with the general population and to find factors associated with QOL.

Clinical and psychological characteristics predict future healthcare use in adults with congenital heart disease.

Background: To deliver adequate care to patients with congenital heart disease (CHD), it is important to know which patients use what type of care. This knowledge is valuable, as modification of these factors may be used as means to regulate healthcare use. Our objective was to examine the predictive value of psychological characteristics for future healthcare use, independent of clinical characteristics.

Multimodality imaging throughout transcatheter aortic valve implantation.

Transcatheter aortic valve implantation (TAVI) is a novel, less-invasive technique used to treat selected patients with severe aortic valve stenosis with a high surgical risk. Noninvasive imaging before, during and after the procedure is of the utmost importance in this minimally invasive procedure. Screening of the patient and sizing of the aortic root by echocardiography and multislice computed tomography is of great importance to ensure success of the TAVI procedure.

Quantification of myocardial perfusion using intravenous myocardial contrast echocardiography in healthy volunteers: comparison with positron emission tomography.

Background: Intravenous myocardial contrast echocardiography (ivMCE) has the potential to evaluate myocardial contraction and perfusion simultaneously. The purpose of this study was to assess quantification of myocardial blood flow (MBF) using ivMCE and to compare this with MBF as measured with positron emission tomography (PET).

Methods: A total of 16 healthy volunteers underwent ivMCE using power pulse inversion and contrast agent microbubbles at rest and during pharmacologically induced vasodilation.
