Summary
A novel Catheter Hole Support Technique enhances catheter support during challenging percutaneous coronary interventions (PCI). This simple method improves equipment delivery in complex coronary artery cases, aiding procedural success.
Area of Science:
- Interventional Cardiology
- Medical Device Technology
Background:
- Percutaneous coronary interventions (PCI) are often complicated by challenging coronary anatomy, including tortuosity, calcification, and unusual takeoffs.
- Optimal catheter support is critical for successful PCI, ensuring precise delivery of devices and guidewires.
- Existing techniques for enhancing catheter support may be complex, costly, or not universally available.
Purpose of the Study:
- To introduce and describe a novel, simple, and cost-effective technique for improving catheter support during PCI.
- To demonstrate the utility of the "Catheter Hole Support Technique" in a challenging case of Right Coronary Artery (RCA) PCI.
Main Methods:
- The "Catheter Hole Support Technique" involves creating a small hole in the guiding catheter.
- This modification is achieved using a standard 22G needle and a 0.018″ shapeable tip support guidewire.
- The technique was successfully applied during PCI for a patient with non-ST-elevation myocardial infarction (NSTEMI).
Main Results:
- The Catheter Hole Support Technique significantly enhanced catheter support and system stability.
- Facilitated successful equipment delivery in a complex Right Coronary Artery intervention.
- The technique proved to be simple to perform and utilized readily available equipment.
Conclusions:
- The Catheter Hole Support Technique is an effective, low-cost method to improve catheter support in challenging PCI procedures.
- This technique offers a valuable adjunct for interventional cardiologists dealing with complex coronary anatomies.
- Further application in various complex PCI scenarios is warranted to confirm its broad utility.

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

240
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...
