Core Areas of Cardiovascular Engineering

Artificial Hearts and Ventricular Assist Devices (VADs)

Cardiovascular engineering has made remarkable strides with devices like artificial hearts and ventricular assist devices (VADs), offering life-saving solutions for patients with end-stage heart failure. These devices range from total artificial hearts—fully implantable mechanical organs designed to completely replace a failing heart—to various VADs that partially support cardiac function. These innovations bridge critical gaps to heart transplantation or provide a permanent alternative when transplantation is not feasible.

• Artificial Hearts:
  • Fully self-contained mechanical units mimicking the pumping action of a natural heart, with advanced sensors and feedback systems that adjust pumping speed in response to physical activity and physiological demands.
  • Examples include the SynCardia Total Artificial Heart, used as a bridge-to-transplant device, and the Carmat bioprosthetic heart, which incorporates biological materials to reduce rejection risk.
  • Artificial hearts are critical for patients whose cardiac function has irreparably failed and who are not candidates for donor heart transplantation.
• Ventricular Assist Devices (VADs):
  • Engineered mechanical pumps attached to one or both ventricles to augment cardiac output and maintain systemic circulation.
  • Left VADs (LVADs): Support the left ventricle, commonly used in patients with left-sided heart failure. Devices like the HeartMate 3 use magnetically levitated rotors to improve durability and reduce hemolysis.
  • Right VADs (RVADs): Support the right ventricle, often deployed in cases of right ventricular failure post LVAD implantation or due to pulmonary hypertension.
  • Biventricular VADs (BiVADs): Provide support for both ventricles in cases of global heart failure.
  • Advancements include sensor-augmented states to prevent pump thrombosis and multi-year battery life to support ambulatory living.

Stents and Angioplasty Devices

The development of stents and angioplasty devices has transformed the treatment of coronary and peripheral artery disease. These devices keep arteries open, restore blood flow, and prevent vessel re-narrowing, dramatically improving outcomes for patients with ischemic heart conditions.

• Stents:
  • Mesh-like tubes implanted in stenotic (narrowed) arteries to scaffold the vessel open, ensuring adequate blood perfusion.
  • Bare-Metal Stents (BMS): Simple metallic scaffolds; affordable and durable, but associated with higher rates of restenosis due to neointimal proliferation.
  • Drug-Eluting Stents (DES): Coated with antiproliferative agents such as sirolimus or paclitaxel, reducing restenosis risk. Examples include the Xience and Endeavor line of stents.
  • Bioabsorbable Stents: Comprised of biodegradable polymers like PLLA or magnesium alloys that gradually dissolve, leaving the artery with restored vessel flexibility.
• Angioplasty Balloons:
  • Inflatable balloons that mechanically dilate vessels narrow due to plaque build-up or thrombus.
  • They precede stent deployment in Percutaneous Coronary Intervention (PCI) to prepare the vessel and reduce complications like dissection.

Heart Valve Prostheses

Engineered heart valves replicate or replace dysfunctional cardiac valves, addressing conditions like aortic stenosis and mitral regurgitation. These prostheses enhance patient outcomes by restoring normal blood flow and relieving cardiac strain.

• Mechanical Heart Valves:
  • Constructed from durable materials such as pyrolytic carbon and titanium, these valves can last several decades.
  • Require lifelong anticoagulation therapy to prevent thromboembolic events.
• Bioprosthetic Valves:
  • Made from biological tissues—porcine, bovine pericardium, or human cadaveric tissue.
  • Offer lower thrombosis risk and generally do not require long-term anticoagulation.
  • Trade-off: limited lifespan (10–15 years) due to tissue degeneration.
• Transcatheter Aortic Valve Replacement (TAVR):
  • Minimally invasive, percutaneous valve implantation, revolutionizing treatment for elderly, high-risk patients.
  • Latest systems include Edwards Sapien and Medtronic CoreValve, with smaller delivery sheaths and improved sealing skirts.
