AI Article Synopsis
- Heart failure is becoming more common, leading to increased use of left ventricular assist devices (LVADs) for patients, either as a temporary solution before a transplant or as a permanent treatment option.
- Continuous-flow LVADs are more frequently used, but they come with risks such as bleeding, blood clots, and infections.
- CT imaging is valuable for identifying complications related to LVADs and ensuring accurate diagnosis, allowing radiologists to better evaluate heart failure patients.
Article Abstract
Heart failure is becoming increasingly prevalent, and more patients are being treated with left ventricular assist devices (LVADs), either as a bridge to transplant or as destination therapy. The use of continuous-flow LVADs is on the rise. LVAD therapy is associated with several classes of complications, including bleeding, thrombosis, and infection. CT imaging can be used effectively to diagnose LVAD complications, including mediastinal hematomas and pericardial, abdominal wall, and retroperitoneal hemorrhage, inflow and outflow graft and aortic thrombi, and driveline and pump pocket infections. CT can also be helpful in cases of device malfunction and can detect outflow graft kinking and inflow cannula misalignment. When interpreting CT scans in patients with LVADs, accessory materials implanted with the device should not be mistaken for hemorrhage or calcification. With training in recognizing LVAD complications, radiologists can play an important role in the evaluation of patients with heart failure.

Impact of Left Ventricular Size on Outcomes Following HeartMate 3 Left Ventricular Assist Device Implantation: Analysis of the European Registry for Patients With Mechanical Circulatory Support (EUROMACS).

We investigated the association of preimplant left ventricular end-diastolic diameter (LVEDD) with outcomes after HeartMate 3 (HM3) left ventricular assist device (LVAD) implantation. Patients from the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) registry who underwent HM3 implantation from August 2014 to February 2023 (n = 834) were analyzed according to preoperative LVEDD: less than or equal to 65 (n = 251), 65-80 (n = 441), and greater than or equal to 80 mm (n = 142). The mean age was 54.

Atrial fibrillation (AF) catheter ablation is safe and effective, though rare cases of takotsubo syndrome (TTS) have been observed without proven causation. This review synthesizes TTS following AF ablation case reports and series. Until October 2024, PubMed/Medline, SCOPUS, and Google Scholar were searched for AF ablation and TTS case reports and series.

Introduction: The clinical utility of metabolic dysfunction-associated steatotic liver disease (MASLD) in predicting subsequent subclinical cardiovascular damages in pediatric population remains poorly understood.
Methods: Data on 1,161 Chinese children aged 10-15 years were used to assess the longitudinal associations of MASLD with subsequent subclinical cardiovascular damages.
Results: Compared with relatively healthy children, children with MASLD had abnormal vascular and cardiac structures, along with reduced cardiac diastolic function at the 2-year follow-up.
Deep learning model for identifying acute heart failure patients using electrocardiography in the emergency room.
Eur Heart J Acute Cardiovasc Care

Department of Medical Informatics, Korea University College of Medicine, Seoul, Republic of Korea.
Background: Acute heart failure (AHF) poses significant diagnostic challenges in the emergency room (ER) because of its varied clinical presentation and limitations of traditional diagnostic methods. This study aimed to develop and evaluate a deep-learning model using electrocardiogram (ECG) data to enhance AHF identification in the ER.
Methods: In this retrospective cohort study, we analyzed the ECG data of 19,285 patients who visited ERs of three hospitals between 2016 and 2020; 9,119 with available left ventricular ejection fraction and N-terminal prohormone of brain natriuretic peptide level data and who were diagnosed with AHF were included in the study.
Right Ventricle Function: The Role of the Forgotten Chamber in Mitral Valve Surgery.
Curr Cardiol Rep

Division of Cardiac Surgery, St. Michael's Hospital, University of Toronto, Toronto, ON, Canada.
Background: Referred to as the "forgotten chamber," the right ventricle (RV) is now widely acknowledged as a significant factor, particularly in certain cardiovascular pathologies. Despite historically being undervalued in comparison to the left ventricle, the RV function is deemed crucial in determining patient outcomes following mitral valve (MV) surgery. In the context of MV surgery, it is important to note that the RV is highly susceptible to dysfunction before, during, and after the surgical procedure.
