Ventricular hypertrophy – Wikipedia

Posted: July 23, 2018 at 7:43 am

Ventricular hypertrophy (VH) is thickening of the walls of a ventricle (lower chamber) of the heart.[1][2] Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur. Ventricular hypertrophy can result from a variety of conditions, both adaptive and maladaptive. Continue reading

Introduction Venous thromboembolic disease (VTE) is estimated to occur in at least 1 to 2 persons per 1000 population annually, manifesting as deep vein thrombosis (DVT), pulmonary embolism (PE) or in combination.1-3 It is the cause of over 100,000 deaths annually and is the most preventable cause of death in hospitalized patients in the United States.4 Despite treatment with anticoagulant therapy, a significant proportion of survivors of acute DVT or PE are at risk of suffering from the disabling sequelae such as the post thrombotic syndrome (PTS), recurrent VTE or chronic thromboembolic pulmonary hypertension (CTEPH).1,5 Given the limitations of medical therapy, promising endovascular treatment modalities have evolved over the past two decades in an effort to mitigate the acute and chronic disability from VTE.6,7 The purpose of this review is to discuss the rationale and evidence for an endovascular treatment approach for high-risk acute DVT and PE patients. The Rationale for an Interventional Approach to Massive and Submassive PE The most dreaded acute complication of PE is death; it is estimated that over 100,000 deaths in hospitalized patients in the United States are attributable to acute PE each year.4 The severity of PE is stratified into massive (PE causing hemodynamic compromise), submassive (PE causing right ventricular dysfunction demonstrable by echocardiography, computed tomography or elevated cardiac biomarkers) and non-massive or low-risk (PE without evidence of RV dysfunction or hemodynamic compromise). The International Cooperative Pulmonary Embolism Registry (ICOPER) demonstrated 90-day mortality rates of 58.3% in patients with massive PE versus 15.1% in sub-massive PE.20 Several studies demonstrate short-term mortality rates of less than 2% in patients with low-risk PE.21-23 Features suggestive of adverse prognosis in acute PE are listed in Table 2.

Ventricular hypertrophy (VH) is thickening of the walls of a ventricle (lower chamber) of the heart.[1][2] Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur. Ventricular hypertrophy can result from a variety of conditions, both adaptive and maladaptive. For example, it occurs in what is regarded as a physiologic, adaptive process in pregnancy in response to increased blood volume; but can also occur as a consequence of ventricular remodeling following a heart attack Continue reading

Ventricular remodeling – Wikipedia

Posted: at 9:50 am

In cardiology, ventricular remodeling (or cardiac remodeling)[1] refers to changes in the size, shape, structure, and function of the heart. This can happen as a result of exercise (physiological remodeling) or after injury to the heart muscle (pathological remodeling).[2] The injury is typically due to acute myocardial infarction (usually transmural or ST segment elevation infarction), but may be from a number of causes that result in increased pressure or volume, causing pressure overload or volume overload (forms of strain) on the heart.

Left ventricular hypertrophy – Wikipedia

Posted: June 26, 2018 at 6:44 am

Left ventricular hypertrophy (LVH) is thickening of the heart muscle of the left ventricle of the heart, that is, left-sided ventricular hypertrophy. While ventricular hypertrophy occurs naturally as a reaction to aerobic exercise and strength training, it is most frequently referred to as a pathological reaction to cardiovascular disease, or high blood pressure.[1] It is one aspect of ventricular remodeling Continue reading

Cardiac Remodeling and Its Significance – verywellhealth.com

Posted: June 23, 2018 at 8:43 am

Cardiac remodeling is a term that refers to changes in the hearts size and shape that occur in response to cardiac disease or cardiac damage. When doctors talk about remodeling, they are usually talking about the left ventricle, though occasionally this term is applied to other cardiac chambers Continue reading

Ventricular septal defect – Wikipedia

Posted: June 21, 2018 at 12:47 am

A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle. The ventricular septum consists of an inferior muscular and superior membranous portion and is extensively innervated with conducting cardiomyocytes Continue reading

What Is the Ejection Fraction? – Verywell Health

Posted: May 12, 2018 at 10:45 am

The ejection fraction is a measurement doctors very commonly use to assess how well the heart is able to pump blood. Specifically, the ejection fraction is the proportion of blood that is pumped from the left ventricle (the main pumping chamber of the heart) with each heart beat. Typically, the left ventricle ejects 55% or more of its blood volume with each beat, so a “normal” ejection fraction is 55% (0.55) or higher Continue reading
