Download or read book The Right Heart written by Sean P. Gaine and published by Springer. This book was released on 2014-05-12 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The heart and lung are intricately linked. When the heart is affected by disease, the lungs will often show some related pathological or clinical conditions and vice versa. Pulmonary heart disease is by definition a condition when the lungs cause the heart to fail. The left ventricle in combination with the other structures in the “left heart” pumps blood throughout the body. The right ventricle (and structures of the “right heart”) pumps blood to the lungs where it is oxygenated and returned to the left heart for distribution. In normal circumstances, the right heart pumps blood into the lungs without any resistance. The lungs usually have minimal pressure and the right heart easily pumps blood through. However when there is lung disease present, like emphysema, chronic obstructive lung disease (COPD) or pulmonary hypertension- the small blood vessels become very stiff and rigid. The right ventricle is no longer able to push blood into the lungs and eventually fails. This is known as pulmonary heart disease. Pulmonary heart disease is also known as right heart failure or cor pulmonale. The chief cause of right heart failure is the increase in blood pressure in the lungs (pulmonary artery).

Book Synopsis The Breathless Heart by : Michele Emdin
Download or read book The Breathless Heart written by Michele Emdin and published by Springer. This book was released on 2016-11-25 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book systematically focuses on central sleep apneas, analyzing their relationship especially with heart failure and discussing recent research results and emerging treatment strategies based on feedback modulation. The opening chapters present historical background information on Cheyne-Stokes respiration (CSR), clarify terminology, and explain the mechanics and chemistry of respiration. Following a description of the physiology of respiration, the pathophysiology underlying central apneas in different disorders and particularly in heart failure is discussed. The similarities and differences of obstructive and central apneas are then considered. The book looks beyond the concept of sleep apnea to daytime CSR and periodic breathing during effort and contrasts the opposing views of CSR as a compensatory phenomenon or as detrimental to the failing heart. The diagnostic tools currently in use for the detection of CSR are thoroughly reviewed, with guidance on interpretation of findings. The book concludes by describing the various forms of treatment that are available for CSR and by explaining how to select patients for treatment.

In the final section, medical, surgical and pharmacological approaches to the treatment of heart failure are discussed in clinical and animal laboratory settings.
Book Synopsis Atlas of Pediatric and Youth ECG by : Gabriele Bronzetti
Download or read book Atlas of Pediatric and Youth ECG written by Gabriele Bronzetti and published by Springer. This book was released on 2017-11-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes in detail the specific aspects of ECG during childhood and adolescence, pursuing an accessible, didactic and easy-to-read approach. Instructive, self-contained and intelligently written, it succeeds in making this diagnostic tool, the interpretation of which is especially complex in younger patients, more comprehensible, while also offering a sound and extensive reference guide for all those who diagnose young patients with electrocardiography. Though ECG produces a relatively simple set of readings, its interpretation and diagnosis are complex. If misinterpreted, a “butterfly effect” of hidden, often neglected heart signals can lead to important and sometimes devastating consequences. Featuring an exceptionally wide range of ECG recordings and examples, the volume sheds new light on the importance of electrophysiological examinations for patients still in their developmental years and provides advice on the use of ECG in connection with recent regulations on the participation of children, adolescents and young athletes in sports. Thanks to the variety of scenarios described, from the most frequent to the most insidious, this work will appeal to a broad readership, from cardiologists and pediatricians to family physicians, anesthesiologists, doctors in sports medicine, students and nurses.

Book Synopsis The right ventricle in volume or pressure overload by : Aleksandra Trzebiatowska-Krzynska
Download or read book The right ventricle in volume or pressure overload written by Aleksandra Trzebiatowska-Krzynska and published by Linköping University Electronic Press. This book was released on 2019-01-07 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is inspired by the gap in knowledge regarding the timing of cardiac surgery and interventions in adult patients with congenital heart disease. There are many parameters used assessing right ventricular function; however, most of them have pitfalls. Understanding the pathomechanisms by which the heart adapts to congenital defects is probably key to find the answer when it is time to intervene and start discussing treatment options. Heart defects are the most frequently occurring congenital disorders. Less than 50% of individuals with moderate to severe congenital heart defects, e.g. transposition of the great arteries (TGA) or tetralogy of Fallot (TOF), survive to adulthood without intervention. Advances in cardiac surgery and better identification of individuals at risk for sudden cardiac death have increased survival rates. Currently, more than 96% of patients with congenital heart disease survive to at least 16 years of age; most undergo corrective surgery but are not cured, and only a few have normal physiology and anatomy. In many cases, the heart must develop mechanisms of adaptation to the changed conditions after surgery. Consequently, correction of the defect creates residual disease with a risk of future complications. To prevent clinical deterioration and to identify the development of complications, patients need lifelong, regular follow up. The choice of followup modalities depends on the cardiac malformation. The right ventricle (RV) plays an important role, as it is often part of the defect or is influenced by the surgery. In the past, research was focused on assessment of left ventricular function (LV), and the RV was “the forgotten ventricle.” Observations and studies in the last few decades brought increased interest into the RV and revealed the importance of the RV in the prognosis of various cardiac diseases. An understanding of RV morphology, pathophysiology and adaptive mechanisms is crucial for further studies of prognosis as well as for research linked to the use of particular diagnostic modalities. When the RV is exposed to increased pressure load, e.g. in atrially corrected transposition of the great arteries (TGA), adaptation affects the cavity volume as well as the wall thickness. When the RV is volume overloaded, adaptation involves enhancement of the RV cavity volume while the wall thickness often remains unchanged under long time. RV ejection fraction (RVEF) gives some information about changes in RV function, but information on myocardial contractility and contractile reserve is also needed. New functional parameters such as strain—also known as myocardial deformation—provide some information about intrinsic myocardial function. In Paper I, we studied functional parameters such as ejection fraction and strain (radial and longitudinal strain for both ventricles) in patients with Tetralogy of Fallot (TOF) and TGA. Longitudinal RV strain was depressed in both patient groups in comparison with that in healthy individuals, and there were additional differences between the two patient groups. In Paper II, we validated three-dimensional echocardiography (3DEcho) against the cardiac magnetic resonance (CMR) gold standard. The study population was limited to patients with TOF. In general, 3DEcho underestimated RV volumes but was able to identify patients with RV dilatation on CMR with high sensitivity. RV longitudinal free wall strain measured by CMR with a cut-off set at -14% identified patients with depressed exercise capacity and low peak oxygen uptake. In Paper III, we studied a new CMR method to quantify and visualise turbulent flow in the heart and vessels. Turbulent flow can be harmful to tissue, blood cells, and endothelium and can contribute to tissue remodeling. In patients with TOF, turbulent flow can be seen as variance in 2DEcho color Doppler. In CMR, increased turbulent kinetic energy (TKE) could be seen with four-dimensional flow. The RV TKE was increased in patients with TOF with pulmonary regurgitation compared with that in healthy controls. In Paper IV, we validated “knowledge-based reconstruction” (KBR), a novel method to calculate RV volume, against CMR in patients with various types of congenital heart defects. Two-dimensional echocardiogram-based threedimensional RV reconstruction is a relatively uncomplicated method that creates a three-dimensional RV model based on a limited number of predefined points of interest (RV structures such as tricuspid annulus, RV free wall, or pulmonary valve). KBR showed good agreement with CMR (intraclass correlation coefficient = 0.84 for RV end-diastolic volume and 0.89 for ejection fraction) but tended to underestimate RV volumes, which is in line with other methods based on ultrasound. Conclusions: 3DEcho is an evolving modality that is able to identify patients with RV dilatation. It can be used clinically for the follow up of patients with congenital heart diseases, especially those with mildly to moderately dilated RVs. When an intervention seems likely, 3DEcho results should be verified by CMR. CMR-derived measurements of longitudinal and radial strain provide a new understanding of RV remodeling and ventricular interdependence in patients with TOF and TGA. Depressed longitudinal strain may indicate a risk of depressed exercise capacity and, in patients with TGA, clinical deterioration. Further studies in larger populations of patients with congenital heart defects are needed, as the altered RV morphology in such patients makes quantitative assessment especially challenging.
