Group 5: Pulmonary hypertension caused by other diseases or conditions, including sarcoidosis, polycythemia vera (which can lead to increased blood viscosity and, subsequently, pulmonary hypertension), vasculitis, and other disorders. Theophylline has a narrow therapeutic index, and adverse effects include seizures, tachycardia, and other cardiac arrhythmias. Cardiac magnetic resonance (CMR) imaging is another form of noninvasive imaging that does not use ionizing radiation. Medscape Education, Exploring the Latest Data on Optimal PAH Treatment Approaches, 2010 Nursing Study Guide on Cor Pulmonale C or pulmonale is a medical condition characterized by the enlargement of the right ventricle of the heart, leading to its failure. Circulation. For example, for massive pulmonary embolism, consider administration of anticoagulation, thrombolytic agents or surgical embolectomy, especially if circulatory collapse is impending; consider bronchodilation and infection treatment in patients with chronic obstructive pulmonary disease (COPD); and consider steroid and immunosuppressive agents in infiltrative and fibrotic lung diseases. The study, by Lin et al, of 692 patients, included 63 patients who were readmitted to the hospital within 31 days after discharge. 2004 Jul. Dandel M, Lehmkuhl H, Knosalla C, Suramelashvili N, Hetzer R. Strain and strain rate imaging by echocardiography - basic concepts and clinical applicability. What is the role of cardiac catheterization in the diagnosis of cor pulmonale? Circulation. 2013 Oct. 39(10):1734-42. Predictors of hospital mortality in hemodynamically stable patients with pulmonary embolism. Jardin F, Vieillard-Baron A. Chang D, Kong X, Zhou X, Li S, Wang H. Unenhanced steady state free precession versus traditional MR imaging for congenital heart disease. Right ventricular enlargement leads to an increase of the transverse diameter of the heart shadow to the right on the posteroanterior view and filling of the retrosternal air space on the lateral view. 2017. [Medline]. 18(3):148-62. There are not enough data available yet regarding the efficacy of these drugs in patients with secondary pulmonary hypertension, such as in patients with COPD. What is the role of chest radiography in the diagnosis of cor pulmonale? Thrombolytic therapy is indicated in patients with acute cor pulmonale due to a pulmonary embolism resulting in hemodynamic instability. 2006 Mar 22;101 Suppl 1:44-6. Hoeper MM. The structure and function of the right ventricle is adversely affected by pulmonary arterial hypertension, induced by a disease process affecting the lungs, their ventilation or blood supply. What are the physical findings characteristic of cor pulmonale? Curr Cardiol Rev. Wang BC, Sundet WD, Goetz KL. Any condition that leads to prolonged high blood pressure in the arteries or veins of the lungs causes a condition called Pulmonary Hypertension. [Medline]. Electrocardiographic (ECG)-gated techniques and respiratory motion suppression have enabled protocols that can provide valuable information about right ventricular (RV) mass, septal flattening, and ventricular function. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. 2013 Oct. 82(10):1743-8. Thus, pulmonary function tests may be required to confirm the presence of other lung pathologies. Barst RJ, Rubin LJ, McGoon MD, Caldwell EJ, Long WA, Levy PS. [Medline]. 2002 What is the role of oxygen therapy in the treatment of cor pulmonale? In contrast, acute cor pulmonale is usually secondary to massive pulmonary embolism. 2006 Mar-Apr. [27]. Most cases of cor pulmonale are secondary to chronic obstructive pulmonary disease. Oxygen therapy is of great importance in patients with underlying chronic obstructive pulmonary disease (COPD), [Medline]. [Medline]. The goal of therapy of cor pulmonale in cystic fibrosis is to correct hypoxemia and lower the elevated pulmonary artery pressures. For example, patients with chronic obstructive pulmonary disease (COPD) who develop cor pulmonale have a 30% chance of surviving 5 years. Of course, the primary problem should be corrected, if possible. Tunariu N, Gibbs SJ, Win Z, et al. [36]. Cor pulmonale can be defined as an alteration in the structure (e.g., hypertrophy or dilatation) and function of the right ventricle (RV) of the heart caused by a primary disorder of the respiratory system resulting in pulmonary hypertension. Pathophysiology of cor pulmonale in chronic obstructive pulmonary disease. What is the role of prostacyclin analogues and receptor agonists in the treatment of cor pulmonale? Eur Heart J. Vasopressin in plasma and cerebrospinal fluid of dogs during hypoxia or acidosis. In addition to estimating RV ejection fraction (RVEF), this imaging modality can estimate RV wall mass. 370(15):1402-11. The main indication for oral anticoagulants in the management of cor pulmonale is in the setting of an underlying thromboembolic event or PAH. See the image below. [Medline]. Pulmonary embolectomy is indicated in patients with acute pulmonary embolism and hemodynamic instability when thrombolytic therapy is contraindicated. What is the role of echocardiography in the diagnosis of cor pulmonale? Splitting of the second heart sound with accentuation of the pulmonic component can be heard in the early stages. Eli Lilly and Company; 2009. Although the use of ultrafast, ECG-gated CT scanning is still experimental, with further improvement, it may be used to evaluate the progression of cor pulmonale in the near future. If you log out, you will be required to enter your username and password the next time you visit. Here, we review the pathophysiology of pulmonary vascular dysfunction in ARDS, consider the beneficial and deleterious effects of mechanical ventilation, describe the incidence and meaning of acute cor pulmonale based on recent studies in large series of patients, and propose a new, although not strictly validated, approach based on the protection of both the lung and right … Ravi H Dave, MD Associate Professor of Medicine, University of California at Los Angeles David Geffen School of MedicineDisclosure: Nothing to disclose. Hemodynamically, this typically presents as a mean pulmonary artery pressure (PAP) above 25 mmHg, which leads to elevated RV systolic pressures and central venous pressures (CVP). Johnson SR, Mehta S, Granton JT. Nocturnal Oxygen Therapy Trial Group. Incidence proportion of acute cor pulmonale in patients with acute respiratory distress syndrome subjected to lung protective ventilation: a systematic review and meta-analysis. Francone M, Dymarkowski S, Kalantzi M, Bogaert J. Real-time cine MRI of ventricular septal motion: a novel approach to assess ventricular coupling. [5]. Pulmonary thromboembolism has a wide range of clinical presentations—from massive embolism with acute and severe hemodynamic instability to multiple chronic peripheral embolisms—that may present with cor pulmonale. In clinical trials, bosentan improved exercise capacity, decreased rate of clinical deterioration, and improved hemodynamics. Kim WJ, Yim JJ, Kim DK, et al. The two images are then analyzed to determine if there are any mismatched perfusion defects, which is suggestive of a pulmonary embolism. What is the pathophysiology of cor pulmonale? By incorporating gadolinium, myocardial scar and fibrosis can also be evaluated via CMR. Am J Physiol. The presence of pulmonary hypertension has long been considered as the conditio sine qua non for the development of a cor pulmonale. Cor pulmonale is a Latin word that means "pulmonary heart," its definition varies, and presently, there is no consensual definition. However, a prospective, multicenter cohort study by Volschan et al indicated that in cases of pulmonary embolism, cor pulmonale may be a predictor of inhospital mortality.
