Summary
Transcatheter aortic valve (TAV) replacement is a key treatment for severe aortic stenosis. This review details TAV complications and assessment strategies for common bioprosthetic valves.
Area of Science:
- Cardiology
- Interventional Cardiology
- Biomedical Engineering
Background:
- Calcific aortic valve stenosis prevalence increases with age.
- Transcatheter aortic valve (TAV) replacement is a primary treatment for high-risk or inoperable patients.
- New complications associated with TAV replacement are often unrecognized.
Purpose of the Study:
- To present a systematic approach for TAV function follow-up.
- To review pathologies uniquely related to TAV.
- To focus on Edwards Sapien and Medtronic CoreValve bioprosthetic valves.
Main Methods:
- Systematic review of TAV function and pathology.
- Focus on Edwards Sapien and Medtronic CoreValve bioprosthetic valves.
- Discussion of diagnostic and treatment strategies for TAV complications.
Main Results:
- TAV replacement is a growing treatment modality.
- Familiarity with TAV appearance is crucial for recognizing complications.
- Specific challenges and advantages exist for dominant TAV prostheses.
Conclusions:
- A systematic approach is needed for TAV follow-up.
- Understanding TAV-specific pathology is essential for patient management.
- Further research into TAV complications and optimization is warranted.

842
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

547
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

397
A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...
