Summary
Transcatheter aortic valve implantation (TAVI) is a high-success procedure for severe aortic stenosis. However, a case report highlights a rare complication: a mobile aortic plaque causing ischemic colitis and death after TAVI.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- Severe symptomatic aortic stenosis necessitates advanced therapeutic options.
- Transcatheter aortic valve implantation (TAVI) offers a less invasive alternative for high-risk patients.
- Vascular complications, including embolization, are known risks associated with TAVI device delivery.
Observation:
- A case of transfemoral TAVI using the Edwards SAPIEN valve is presented.
- A mobile mass, likely atherosclerotic plaque, was found attached to the implanted valve.
- The patient subsequently developed ischemic colitis.
Findings:
- The mobile aortic plaque is a potential embolic source during TAVI.
- Embolization from aortic plaque can lead to severe systemic complications.
- This complication resulted in patient mortality.
Implications:
- Careful patient selection and pre-procedural imaging are crucial to identify potential embolic sources.
- Improved techniques for managing embolic risk during TAVI may be warranted.
- Understanding rare complications is vital for enhancing TAVI safety and patient outcomes.

01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
