Summary
Managing complications from durable mechanical circulatory support (DMCS) is crucial for patients awaiting heart transplants or on destination therapy. Addressing issues like de novo aortic insufficiency and infections improves quality of life and reduces hospital readmissions.
Area of Science:
- Cardiology
- Medical Devices
- Surgical Innovation
Context:
- Durable mechanical circulatory support (DMCS) use for bridge to transplant (BTT-DMCS) began in Japan in 2011, expanding to destination therapy (DT-DMCS) with insurance coverage in 2021.
- Despite technological advancements, managing DMCS-related complications presents significant challenges, leading to high patient readmission rates and increased healthcare burdens.
- Key complications include de novo aortic insufficiency (dnAI), driveline infections (DLI), and external outflow graft obstruction (EOGO), each requiring specific management strategies.
Purpose:
- To highlight the persistent challenges in managing complications associated with durable mechanical circulatory support (DMCS).
- To discuss current interventions and diagnostic tools for prevalent DMCS complications such as dnAI, DLI, and EOGO.
- To emphasize the importance of multidisciplinary collaboration and optimized intervention timing for improving patient outcomes.
Summary:
- De novo aortic insufficiency (dnAI) is a major complication linked to chronic right heart failure, with interventions like bioprosthetic aortic valve replacement (bioAVR) and central aortic valve closure (CAVC) offering varied solutions.
- Driveline infections (DLI), often caused by resistant bacteria, require intensive wound care, driveline repositioning, and extended antibiotic treatments, with 18-FDG PET/CT aiding diagnosis.
- External outflow graft obstruction (EOGO), commonly due to seroma compression, can precipitate circulatory failure and may necessitate surgical or catheter-based interventions.
Impact:
- Effective management of DMCS complications can significantly improve patient quality of life and reduce the workload on healthcare systems.
- Optimizing intervention timing and preventing reoperations are critical for enhancing the long-term efficacy and success of DMCS therapy.
- Further research and standardized protocols are needed to address the complexities of DMCS-related morbidities and improve patient survival and well-being.

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...
