Isolated Right Ventricular Mechanical Support: Outcomes and Prognosis
ASAIO Journal (American Society for Artificial Internal Organs : 1992)
|May 17, 2017
Summary
Isolated right ventricular assist device (RVAD) support is rare. This study reports 30-day and 1-year survival rates of 72.7% and 54.6% for patients receiving isolated RVADs.
Area of Science:
- Cardiology
- Mechanical Circulatory Support
- Cardiac Surgery
Background:
- Right ventricular (RV) failure requiring isolated mechanical support is uncommon.
- Existing data on outcomes are limited to case reports.
Purpose of the Study:
- To evaluate outcomes, including survival, for patients receiving isolated RV assist devices (RVADs).
- To describe the duration of support and adverse events in this patient cohort.
Main Methods:
- Retrospective review of the Mechanical Assist Device Database at Columbia University (2007-2015).
- Inclusion criteria: patients receiving isolated RVADs without left ventricular mechanical support.
- Evaluation of survival, support duration, ICU length of stay, and adverse events.
Main Results:
- Eleven patients received isolated RVADs.
- Average duration of support was 13.6 days (median 12 days).
- Thirty-day survival was 72.7%; 1-year survival was 54.6%.
Conclusions:
- This is the first case series to report 30-day and 1-year outcomes for isolated RV mechanical support.
- An interdisciplinary algorithm is proposed, prioritizing medical therapy before invasive mechanical support for persistent end-organ damage.

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...

677
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,...

578
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...

973
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...

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
