Insights

Transcatheter aortic valve implantation (TAVI) can cause conduction disturbances, often requiring pacemakers. Minimizing these risks is vital as TAVI use expands to younger, healthier patients.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Electrophysiology

Background:

  • Conduction disturbances and permanent pacemaker implantation are common TAVI complications.
  • Predictors include pre-existing right bundle branch block, short septum, deep implantation, and valve type.
  • New pacemaker implantation and left bundle branch block increase mortality and heart failure hospitalizations.

Purpose of the Study:

  • To review the incidence, pathophysiology, and consequences of TAVI-related conduction disturbances.
  • To discuss current and emerging preventive strategies.
  • To provide an evidence-based management framework for TAVI-related conduction issues.

Main Methods:

  • Review of existing literature on TAVI complications.
  • Analysis of predictors for conduction disturbances.
  • Discussion of ongoing clinical trials and novel techniques.

Main Results:

  • TAVI is associated with significant risks of conduction abnormalities and pacemaker needs.
  • Specific patient and procedural factors predict these complications.
  • New conduction disturbances post-TAVI are linked to adverse outcomes.

Conclusions:

  • Minimizing conduction disturbances is crucial for expanding TAVI to lower-risk populations.
  • Refined implantation techniques and new treatments are under investigation.
  • Evidence-based management and risk stratification are essential for optimal TAVI outcomes.

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Aortic Regurgitation I: Introduction01:15

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 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...

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 IV: Nursing Management01:17

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...

Transient Ischemic Attack l: Introduction01:26

Transient 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...
