Insights

Destination therapy with ventricular assist devices (VADs) is becoming a viable alternative to heart transplantation. Improved VAD technology and patient management are narrowing survival gaps for end-stage heart failure patients.

Area of Science:

  • Cardiology
  • Medical Devices
  • Heart Failure Management

Background:

  • Cardiac transplantation is the optimal treatment for end-stage heart failure, but organ availability is limited.
  • Destination therapy (DT) using durable ventricular assist devices (VADs) offers an alternative for patients ineligible for transplantation.
  • The advent of continuous-flow VADs has significantly increased DT-VAD implantations.

Purpose of the Study:

  • To review current indications for durable VAD implantation for destination therapy.
  • To summarize outcomes following durable VAD implantation for destination therapy.

Main Methods:

  • Review of current literature on destination therapy VADs.
  • Analysis of outcomes including survival rates and adverse events.
  • Comparison of DT-VADs with cardiac transplantation.

Main Results:

  • In 2014, DT-VADs represented 46% of all VAD implants.
  • One- and 2-year survival rates for DT-VADs are comparable to cardiac transplantation.
  • Survival differences between VADs in transplant-eligible versus DT patients are narrowing.
  • Adherence to management protocols can reduce VAD-related adverse events.

Conclusions:

  • Advancements in VAD technology, patient selection, and management have improved outcomes for non-transplant-eligible patients.
  • DT-VADs are emerging as a competitive alternative to traditional heart transplantation.
  • Continued improvements are expected to further enhance the role of VADs in heart failure management.

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
