Summary
Transcatheter aortic valve replacement (TAVR) can involve rare complications, even for experienced surgeons. This report details a successful treatment for supra-annular prosthesis dislocation during TAVR.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure for aortic stenosis.
- Despite advancements, TAVR carries risks of rare and complex complications.
- Experienced operators can encounter unexpected challenges during TAVR.
Observation:
- A case of supra-annular dislocation of a balloon-expandable prosthesis during TAVR is presented.
- The complication arose due to loss of capture of the temporary transvenous pacemaker lead.
- This specific complication highlights potential procedural vulnerabilities.
Findings:
- The supra-annular dislocation was successfully managed by repositioning the prosthesis.
- Retraction of the pacemaker lead towards the abdominal aorta resolved the dislocation.
- This demonstrates a feasible interventional strategy for this rare complication.
Implications:
- This case report expands the understanding of potential TAVR complications.
- It offers a practical solution for managing supra-annular prosthesis dislocation.
- Highlights the importance of vigilant monitoring of pacing leads during TAVR.

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...

01:15Aortic Regurgitation I: Introduction
92
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

96
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...

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...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
