Cardiac catheterization in pulmonary arterial hypertension: Tips and tricks to enhance diagnosis and guide therapy.

Cardiac catheterization (CC) is essential for the diagnosis of pulmonary hypertension (PH), and for its characterisation. It allows distinction between pre- and post-capillary PH which, when integrated with other non-invasive data, facilitates classification into one of the 5 diagnostic groups defined by international PH guidelines. CC also provides valuable information for the risk stratification of patients with PH, guiding management and the type and intensity of treatment.

Pregnancy in women with a Fontan circulation: Short and long-term outcomes.

Background: The Fontan circulation procedure is the palliative surgery of choice for patients with single ventricle physiology, many of whom are now reaching childbearing age due to advances in care. Our study examines the impact of pregnancy on women with Fontan circulation, assessing both short and long-term outcomes.

Methods: We retrospectively analysed pregnancies in women with Fontan circulation at our centre from 2005 to 2023, including a matched non-pregnant, nulliparous cohort for comparison.

Morbidity and mortality in adults with a Fontan circulation beyond the fourth decade of life.

Aims: To evaluate the late outcomes of adults (above 35 years) with a Fontan-type circulation, for whom current data on morbidity and mortality are lacking.

Methods And Results: Data were collected retrospectively on consecutive patients with Fontan circulation above the age of 35 years followed in three European specialist centres. Overall, 115 Fontan patients were included [median age 35 (range 35-48) years, 47.

Multifaceted Fontan Patients and Their Response to Pregnancy.

We present 4 patients with Fontan circulation who underwent successful pregnancies, albeit with complications that required close monitoring and timely intervention. Each Fontan patient presents with a unique clinical picture, making risk stratification challenging but all the more important.

Management of pulmonary arterial hypertension during pregnancy.

Introduction: Pulmonary arterial hypertension (PAH) is defined as a mean pulmonary artery pressure >20 mmHg and pulmonary vascular resistance >2 Wood Units (WU) on right-heart catheterization. Pregnancy is generally contraindicated in PAH, it is associated with high maternal mortality. Despite current recommendations, the number of women with PAH wishing to become pregnant is increasing.

Advanced heart failure in adult congenital heart disease: the role of renal dysfunction in management and outcomes.

Aims: Previous studies in adult congenital heart disease (CHD) have demonstrated a link between renal dysfunction and mortality. However, the prognostic significance of renal dysfunction in CHD and decompensated heart failure (HF) remains unclear. We sought to assess the association between renal dysfunction and outcomes in adults with CHD presenting to our centre with acute HF between 2010 and 2021.

Microvascular Dysfunction in Dilated Cardiomyopathy: A Quantitative Stress Perfusion Cardiovascular Magnetic Resonance Study.

Objectives: This study sought to quantify myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) in dilated cardiomyopathy (DCM) and examine the relationship between myocardial perfusion and adverse left ventricular (LV) remodeling.

Background: Although regarded as a nonischemic condition, DCM has been associated with microvascular dysfunction, which is postulated to play a role in its pathogenesis. However, the relationship of the resulting perfusion abnormalities to myocardial fibrosis and the degree of LV remodeling is unclear.

Sex- and age-based differences in the natural history and outcome of dilated cardiomyopathy.

Aim: To evaluate the relationship between sex, age and outcome in dilated cardiomyopathy (DCM).

Methods And Results: We used proportional hazard modelling to examine the association between sex, age and all-cause mortality in consecutive patients with DCM. Overall, 881 patients (290 women, median age 52 years) were followed for a median of 4.
