Insights

A novel coaxial femoral approach using 16 Fr/14 Fr/6 Fr sheaths allows safe single-access Impella-supported percutaneous coronary intervention (PCI). This strategy enhances procedural efficiency and reduces bleeding risk when radial access is not feasible.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • Complex cardiac arrest cases often require combined veno-arterial extracorporeal membrane oxygenation (VA-ECMO), Impella left-ventricular unloading, and urgent percutaneous coronary intervention (PCI).
  • Vascular access can be a significant procedural challenge in these high-risk patients.
  • Traditional single-access Impella-PCI methods present trade-offs between workflow efficiency and bleeding risk, especially when radial access is not an option.

Purpose of the Study:

  • To present a rescue strategy for achieving single-access Impella-supported PCI in cases where radial access is unobtainable.
  • To describe a coaxial sheath configuration that facilitates complex interventions while minimizing bleeding complications.

Main Methods:

  • A coaxial 16 Fr/14 Fr/6 Fr sheath configuration was employed in the left common femoral artery.
  • A 16 Fr Medikit sheath was placed, followed by coaxial insertion of a 14 Fr peel-away sheath for Impella CP implantation.
  • A 6 Fr sheath was advanced through the Impella sheath to enable percutaneous coronary intervention (PCI).

Main Results:

  • The described coaxial strategy successfully enabled single-access Impella-supported PCI in a patient with refractory ventricular fibrillation and coronary artery occlusion.
  • The procedure involved VA-ECMO via right femoral cannulation and Impella CP implantation through the coaxial sheath system.
  • Successful stent deployment was achieved via the 6 Fr sheath, and all sheaths except the 16 Fr were removed post-procedure without bleeding complications.

Conclusions:

  • A coaxial 16 Fr/14 Fr/6 Fr femoral approach provides a safe and effective method for single-access Impella-supported PCI.
  • This technique combines procedural efficiency with a reduced risk of bleeding, particularly valuable when radial access is not feasible.
  • This strategy offers a viable solution for complex cardiac arrest interventions requiring mechanical circulatory support and revascularization.

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Nursing Interventions I: Taxonomy of Nursing Interventions

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Data Reporting and Recording

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
