Insights

Aortic atherothrombotic lesions are common in patients undergoing transfemoral TAVR. While short-term outcomes showed no significant impact, long-term mortality was numerically higher in patients with these lesions.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Vascular Surgery

Background:

  • Aortic atherothrombotic lesions pose risks of systemic embolization and adverse events during interventional procedures.
  • Understanding the impact of aortic atherosclerosis is crucial for patient management in TAVR.

Purpose of the Study:

  • To evaluate the association between the extent of aortic atherosclerosis and clinical outcomes following transfemoral transcatheter aortic valve replacement (TAVR).

Main Methods:

  • A single-center observational study included 278 patients undergoing transfemoral TAVR.
  • Preoperative computed tomography assessed aortic atherosclerosis, defining lesions as intimal thickening ≥4mm or mobile/ulcerated atheroma.
  • Patients were grouped based on the presence or absence of atherothrombotic lesions, with outcomes including mortality, stroke, embolism, and renal function monitored.

Main Results:

  • Atherothrombotic lesions were identified in 41.4% of patients; those with lesions had worse baseline renal function.
  • No significant short-term differences in all-cause death, stroke, systemic embolism, or worsening renal function were observed within 1 month.
  • Over a median 3-year follow-up, all-cause mortality was numerically higher in patients with atherothrombotic lesions.

Conclusions:

  • Atherothrombotic lesions are frequently detected in patients undergoing transfemoral TAVR.
  • Aortic atherosclerosis did not significantly affect short-term adverse outcomes post-TAVR.
  • A trend towards increased long-term mortality was noted in patients with atherothrombotic lesions.

Aortic Regurgitation III: Medical Management

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

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...

Aortic Regurgitation I: Introduction

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...

Aortic Regurgitation IV: Nursing Management

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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
