Aortic Regurgitation III: Medical Management01:25

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...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

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...

Upper-extremity Approach for Secondary Access in Transfemoral Transcatheter Aortic Valve Implantation

Published on: August 8, 2025

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Surgical Innovation

Background:

  • Aortic stenosis necessitates effective treatment options.
  • Percutaneous transcatheter aortic valve replacement (TAVR) emerged in 2002 as a key intervention.
  • Anesthesia options include balanced general anesthesia or monitored anesthesia care with local anesthesia.

Purpose of the Study:

  • To evaluate the efficacy and safety of TAVR.
  • To highlight critical factors for successful TAVR procedures.
  • To address major concerns associated with TAVR.

Main Methods:

  • Review of TAVR registries and clinical trials (e.g., PARTNER trial).
  • Analysis of transfemoral and transapical TAVR approaches.
  • Assessment of procedural outcomes and complications.

Main Results:

  • TAVR demonstrates excellent success and survival rates.
  • Stroke and paravalvular insufficiency are significant concerns.
  • Effective TAVR outcomes are linked to procedural preparedness.

Conclusions:

  • TAVR is a viable treatment for aortic stenosis.
  • Mitigating risks like stroke and paravalvular insufficiency is essential.
  • Thorough knowledge of procedural specifics is key to successful TAVR.
