Case Reports in Critical Care
|January 9, 2026
Summary
Primary cardiac sarcoma causing left ventricular outflow tract (LVOT) obstruction is rare. Early echocardiography in a young male with unexplained symptoms led to prompt diagnosis and life-saving surgery for this aggressive tumor.
Area of Science:
- Cardiology
- Oncology
- Diagnostic Imaging
Background:
- Primary cardiac sarcomas are rare, aggressive tumors often diagnosed late.
- Left ventricular outflow tract (LVOT) obstruction is a rare but critical complication.
Purpose of the Study:
- To report a case of primary cardiac sarcoma presenting with LVOT obstruction.
- To highlight the importance of early diagnosis and intervention.
Main Methods:
- Case report of a 33-year-old male with progressive dyspnea and hemodynamic instability.
- Point-of-care transthoracic echocardiography identified an intracardiac mass causing dynamic LVOT obstruction.
- Urgent surgical resection of the cardiac sarcoma.
Main Results:
- The patient experienced cardiac arrest during intubation, requiring resuscitation.
- Surgical intervention confirmed infiltrative cardiac sarcoma with positive margins.
- Postoperative recovery was favorable with rapid weaning from support.
Conclusions:
- Clinical vigilance for unexplained cardiopulmonary symptoms is crucial.
- Early echocardiography is vital for prompt diagnosis of rare cardiac emergencies.
- Timely surgical intervention can be life-saving in obstructive shock from cardiac sarcoma.

278
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

393
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...

435
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...

457
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

444
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
