  • 9-month-old baby born with 5 holes in heart, 3D printed heart models help surgeons save his life
  • (3ders.org) Medical 3D printing innovations are slowly but steadily changing the medical landscape, but there is one among them that is already saving lives on a remarkable scale. It’s also the simplest, but no less important: 3D printed replica models of organs or fractures that can be used by doctors to prepare complex and unusual surgeries. The importance of this technique is again illustrated by Chinese doctors in Nanjing, China. There, the nine-month-old boy Chen Chen has just undergone successful and crucial heart surgery that had been prepared with the help of 3D printed heart replicas.

  • Mechanism of Resveratrol Action in PAH Identified by Study
  • (Lung Disease News) Researchers at Peking Union Medical College Hospital in Beijing discovered a novel pathway of cell cycle regulation in pulmonary arterial hypertension (PAH) disease progression. A collection of experiments described in the researcher’s study, “Regulation of Cell Cycle Regulators by SIRT1 Contributes to Resveratrol-Mediated Prevention of Pulmonary Arterial Hypertension,” demonstrated that Silence Information Regulator 1 (SIRT1) signaling is implicated in PAH and is the pathway of action for resveratrol-mediated attenuation of PAH.

  • New Method of Evaluating Right Ventricular Function Predicts Pulmonary Arterial Hypertension Outcome in Patients
  • (Lung Disease News) People with pulmonary hypertension have high blood pressure in the lung arteries rather than in regular circulation. The disease can be caused by several other conditions and diseases, including connective tissue disease, congenital abnormalities of the heart, emphysema, and fibrosis in the lungs. Regardless of what leads to its development, pulmonary hypertension is a serious disease that is difficult to treat. Many patients require a heart-lung transplant, medications to control the high blood pressure in the lungs, and some die from their disease. The median life expectancy for those with PH who remain untreated is 2.8 years.

  • Early surgery for mitral regurgitation, before clinical triggers emerge, has best outcomes
  • (Medical Xpress) About 2% of the U.S. population has mitral valve regurgitation, which left untreated, can remain mild or lead to arrhythmia or heart failure. Timing of surgery is a matter of controversy, with guidelines suggesting "watchful waiting" or medical treatment until heart failure or poor function becomes apparent. Now a report in the Journal of Thoracic and Cardiovascular Surgery, the official publication of the American Association for Thoracic Surgery (AATS), finds that allowing patients to reach these "surgical triggers" doubles the risk of postoperative mortality and heart failure compared to those who undergo early surgery.

  • The zinc transporter ZIP12 regulates the pulmonary vascular response to chronic hypoxia
  • (Nature) The typical response of the adult mammalian pulmonary circulation to a low oxygen environment is vasoconstriction and structural remodelling of pulmonary arterioles, leading to chronic elevation of pulmonary artery pressure (pulmonary hypertension) and right ventricular hypertrophy. Some mammals, however, exhibit genetic resistance to hypoxia-induced pulmonary hypertension.

  • Pulmonary Arterial Hypertension Market Expected to Expand due to Rise in Incidence of Heart Failures
  • (medGadget) The global pulmonary arterial hypertension market is expected to rise proportionate to the rise in the number of heart failures. Pulmonary arterial hypertension is characterized by restrained blood flow via the pulmonary arteries, which leads to a constant increase in pulmonary vascular resistance and finally failure of the right side of the heart. PAH is one of five groups of pulmonary hypertension, as described by the World Health Organization (WHO). PAH develops due to the narrowing, blocking, and thickening of the pulmonary arteries.

  • Selective enhancement of endothelial BMPR-II with BMP9 reverses pulmonary arterial hypertension.
  • (PubMed) Genetic evidence implicates the loss of bone morphogenetic protein type II receptor (BMPR-II) signaling in the endothelium as an initiating factor in pulmonary arterial hypertension (PAH). However, selective targeting of this signaling pathway using BMP ligands has not yet been explored as a therapeutic strategy. Here, we identify BMP9 as the preferred ligand for preventing apoptosis and enhancing monolayer integrity in both pulmonary arterial endothelial cells and blood outgrowth endothelial cells from subjects with PAH who bear mutations in the gene encoding BMPR-II, BMPR2.

  • 7 Avoidable Habits That Cause Fatal Respiratory Disorders
  • (Nigerian Bulletin) The respiratory system plays a critical role in the proper functioning of the body. It comprises the nose externally, trachea (or windpipe), bronchi as well as a branching network of bronchioles which open into the alveoli (air sacs) within the lung tissue. This system is involved in the exchange of gases, notably oxygen and carbon dioxide at the level of the alveoli. Needless to mention that oxygen which we breathe in is essential for the survival of body tissues which in turn generate carbon dioxide as a by-product of metabolism that must be expelled from the body through the lungs.

  • Pro-inflammatory Signature of the Dysfunctional Endothelium in Pulmonary Hypertension: Role of MIF/CD74 Complex
  • (ATS Journals) Inflammation and endothelial dysfunction are considered two primary instigators of pulmonary arterial hypertension (PAH). CD74 is a receptor for the pro-inflammatory cytokine macrophage migration-inhibitory factor (MIF). This ligand/receptor complex initiates survival pathways and cell proliferation, triggers the synthesis/secretion of major pro-inflammatory factors and cell adhesion molecules. Objectives: We hypothesized that MIF/CD74 signaling pathway is over-expressed in idiopathic PAH (iPAH) and contributes to a pro-inflammatory endothelial cell (EC) phenotype.

  • Echocardiography and Pulmonary Arterial Hypertension: A Detailed Look
  • (Pulmonary Hypertension RN) Echocardiogram (or echo) is an ultrasound-based test that can tell us a great deal about your heart.  By bouncing and receiving ultrasound waves off your heart and adjacent structures, we can generate images of your heart.  We can learn about the size and function of the right and left side of your heart and the valves. We can estimate pressures but not directly measure pressures.  As we have emphasized in many different places on this website, an echocardiogram is not a substitute for a right heart catheterization.  The diagnosis of PAH should never be made without a right heart catheterization and treatment should not be started until after a right heart catheterization is completed.  Let’s take a more detailed look at the components of the echocardiogram report.

  • (Medscape) Hepatopulmonary syndrome and portopulmonary hypertension are cardiopulmonary complications, which are not infrequently seen in patients with liver disease and/or portal hypertension. These entities are both clinically and pathophysiologically different: the hepatopulmonary syndrome is characterized by abnormal pulmonary vasodilation and right-to-left shunting resulting in gas exchange abnormalities, whereas portopulmonary hypertension is caused by pulmonary artery vasoconstriction leading to hemodynamic failure.
