Summary
A soft tissue sarcoma patient developed dyspnea due to a right ventricular outflow tract mass. Multimodality imaging, including echocardiography and CTPA, was crucial for diagnosis, highlighting malignancy suspicion.
Area of Science:
- Cardiology
- Oncology
- Radiology
Background:
- A 58-year-old male with a history of soft tissue sarcoma in remission presented with progressive dyspnea.
- This symptom progression prompted further investigation into potential cardiac or pulmonary causes.
Observation:
- Transthoracic echocardiography revealed right ventricular dilation and a significant elevation in right ventricular systolic pressure (RVSP) to 110 mm Hg.
- A lobulated mass was identified within the right ventricular outflow tract (RVOT), causing obstruction.
- Microbubble contrast administration demonstrated perfusion within the mass, raising suspicion for malignancy.
Findings:
- CT pulmonary angiogram (CTPA) confirmed the RVOT mass but ruled out pulmonary embolism.
- The imaging findings collectively suggested a malignant mass within the right ventricular outflow tract.
Implications:
- This case underscores the utility of a multimodality imaging approach in diagnosing complex cardiac masses.
- Accurate and timely diagnosis of RVOT masses is critical for patient management and treatment planning.
- Integrating echocardiography and CTPA aids in differentiating benign from malignant etiologies in the RVOT.

01:21Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
01:20Mitral Regurgitation I: Introduction
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
01:22Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
01:15Aortic Regurgitation I: Introduction
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:11Pyloric Obstruction
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
