|June 3, 2024
Summary
A leadless pacemaker caused delayed cardiac tamponade and effusion due to ventricular wall penetration. Surgical intervention was required to address this serious complication.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Device Technology
Background:
- Leadless pacemakers offer a minimally invasive alternative for cardiac rhythm management.
- Complications, though rare, require careful consideration and prompt management.
Observation:
- An 87-year-old male presented with delayed cardiac tamponade 55 minutes post-leadless pacemaker implantation.
- Recurrent pericardial effusion was noted 20 days later.
Findings:
- Electrocardiogram-gated enhanced cardiac computed tomography identified leadless pacemaker tines penetrating the right ventricular free wall.
- The penetration was located on the lateral side of the device.
Implications:
- This case highlights a rare but severe complication of leadless pacemaker implantation.
- Prompt diagnosis and surgical intervention (off-pump hemostatic surgery) are crucial for managing ventricular perforation by cardiac devices.

Chambers of the Heart
10.0K
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Heart Valves
14.9K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Disturbances in Heart Rhythm
5.3K
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...

Mitral Regurgitation I: Introduction
1.3K
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Mitral Stenosis I: Introduction
1.8K
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...

Dysrhythmias II: Classification of Tachyarrhythmias
735
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...
