A Novel Unidirectional-Valved Shunt Approach for End-Stage Pulmonary Arterial Hypertension: Early Experience in Adolescents and Adults

Despite advances in treatment of idiopathic pulmonary arterial hypertension (IPAH), there remains no medical cure and patients can experience disease progression leading to right heart failure, progressive exercise intolerance and death. The reversed Potts shunt (left pulmonary artery to descending aorta) was re-introduced for treatment of end-stage IPAH to permit decompression of the suprasystemic right ventricle by right to left shunting, with preservation of upper body oxygenation. The shunt has the potential to delay the need for lung transplantation and offer a treatment for those who are transplant ineligible.

In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple inter...

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

In conclusion, high-dose NR induces the onset of WAT dysfunction, which may in part explain the deterioration of metabolic health. Towards a Rigorous Definition of Cellular Senescence https://www.fightaging.org/archives/2019/11/towards-a-rigorous-definition-of-cellular-senescence/ The accumulation of lingering senescent cells is a significant cause of aging, disrupting tissue function and generating chronic inflammation throughout the body. Even while the first senolytic drugs capable of selectively destroying these cells already exist, and while a number of biotech companies are working on the productio...

Pulmonary arterial hypertension (PAH) is a severe cardiopulmonary disease that is characterized by increased vascular resistance and early progression to right heart failure clinically, which occurs due to plexigenic, hypertrophic, and fibrotic effacement of distal pulmonary arterioles without systemic vascular involvement.1 There are several features that distinguish PAH from many other vascular disorders. First, the prevalence of PAH is ∼20 per 1,000,000 individuals, and, thus, it is classified as rare.

This report is the first instance in which a patient with severe PAH, survived a successful atrial septal defect (ASD) repair and bilateral lung transplantation during puerperium. Patient concerns: A 42-year-old pregnant woman with congenital heart disease (CHD) and severe PAH was admitted to our hospital for the management of pregnancy and delivery. The patient was diagnosed with severe PAH in 2013, and no significant improvements or deteriorations were found until this pregnancy-related hospital admission. Diagnosis: The patient was diagnosed with CHD and severe PAH in 2013 with color Doppler echocardiography, righ...

Cystic fibrosis (CF) is the most common genetically inherited disease in the Caucasian population [1]. Respiratory manifestations of CF include reduction of mucus clearance, chronic pulmonary infections, and bronchiectasis, causing a progressive respiratory failure that is the primary cause of death in CF patients. Advanced CF might be complicated by pulmonary hypertension, right ventricular hypertrophy, and right heart failure [2]. Bilateral lung transplantation (LUTX) is a viable option for CF, providing a significant survival benefit [3].

Abstract Pulmonary hypertension is a term used to describe a complex multifactorial group of conditions diagnosed by an elevated mean pulmonary artery pressure of 20 mm Hg or higher on right heart catheterization. The diagnosis of pulmonary hypertension in pregnancy is important, as it is associated with high rates of maternal morbidity and mortality, even with modern management. Diagnostic testing is important for establishing the diagnosis, type, and severity of pulmonary hypertension, which in turn, dictates treatment options. Echocardiographic assessment is the first step in diagnosis and the gold standard for...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...
