Background:

Aortic root thrombosis (ART) in left ventricular assist device (LVAD) patients has gained attention due to potential clinical consequences. This study aims to assess the clinical outcomes associated with ART in LVAD patients.

Methods:

We retrospectively evaluated adult patients who received LVAD implants at our center between January 2020 and March 2022. Pre-operative data, including demographics, laboratory values, and echocardiographic assessments, were similar between the ART and non-ART groups. Composite outcomes such as cerebrovascular events, pump thrombosis, myocardial infarction, embolic events, bleeding, right ventricular (RV) failure, and mortality post-discharge were examined.

Results:

The study included 44 outpatients (36 HeartMate 3, 8 HeartWare). ART was identified in 20 patients (45%) post-discharge. The "no ART" group had a mean age of 47±10 years (23 of 24 patients were male, 95.8%), while the "ART" group had a mean age of 48±12 years (15 of 20 patients were male, 75%), with no significant age difference (p>0.05). Thrombosis occurred at a median of 59 days post-implantation, primarily affecting the non-coronary cusp in 50% of the ART group. The median follow-up period was 416 days. No significant differences were found in composite outcomes (p=0.276), mortality (p=0.814), bleeding (p=0.808), or RV failure (p=0.197).

Conclusion:

ART may be under-recognized in LVAD patients, potentially leading to cardiac and end-organ damage. While ART does not significantly impact mortality, it emphasizes the need for careful management of LVAD patients.

Patient-centered Care

Patient-centered Care

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Prevalence and Incidence

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

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...

Venous Thrombosis I: Introduction

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Lattice Centering and Coordination Number

Lattice Centering and Coordination Number

The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.
