Insights
A Teflon patch used to repair a cardiac injury detached, leading to a pseudoaneurysm. Percutaneous closure with an Amplatzer Vascular Plug 4 successfully treated this rare complication.
Area of Science:
- Cardiology
- Cardiac Surgery
- Interventional Cardiology
Background:
- Previous chest radiation therapy can predispose patients to cardiac complications.
- Aortic stenosis and coronary artery disease are common cardiovascular conditions requiring surgical intervention.
Abstract:
We report the case of a 66-year-old man, with a history of previous chest radiation therapy admitted to ED for heart failure. The patient was diagnosed with severe aortic stenosis and multivessel coronary disease and underwent surgical aortic valve replacement and coronary artery by pass grafts. Cardiac surgery was complicated by a left ventricular perforation by a venting catheter. The laceration was repaired with a Teflon patch apparently successful. Four months later, a CT scan performed for oncological follow-up demonstrated the complete detachment of the Teflon patch and the formation of a left ventricular pseudoaneurysm. The pseudoaneurysm was effectively treated percutaneously using an Amplatzer Vascular Plug 4.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
Seedless Vascular Plants
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
