要旨

Rationale:

In patients with atrial fibrillation (AF) complicated by severe aortic stenosis (AS), atrioventricular node ablation (AVNA) combined with permanent pacemaker implantation is an effective treatment strategy, especially when conventional rhythm control methods fail.

Patient Concerns:

An 88-year-old female with a 40-year history of paroxysmal palpitations and chest tightness, with significant worsening of symptoms over the past 20 days. Despite undergoing AF ablation 5 years ago, her symptoms and arrhythmia burden persisted.

Diagnosis:

Long-standing (24 years) AF, severe AS, and a history of failed radiofrequency catheter ablation for AF.

Interventions:

The patient underwent left bundle branch pacing followed by AVNA.

Outcomes:

During the 9-month follow-up period, her palpitations completely resolved, with no recorded atrial arrhythmias. The AF's impact on quality of life score significantly improved, and her performance on the 6-minute walk test markedly increased, indicating significant functional enhancement.

Lessons:

This case demonstrates that left bundle branch pacing combined with AVNA is clinically effective and technically feasible for AF patients in the elderly population with severe AS, particularly when conventional rhythm control methods fail. This approach offers an effective option for symptom relief and functional improvement in this challenging patient population.

Mitral Stenosis III: Medical Management

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...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Aortic Regurgitation III: Medical Management

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...

Mitral Stenosis I: Introduction

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Regurgitation III: Medical Management

Mitral Regurgitation III: Medical Management

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
