Acute Heart Failure and Complete Heart Block in a Patient with Recurrent Diffuse Large B-Cell Lymphoma: A Case Report.
Am J Case Rep
December 2024
Division of Academic Affairs, Orlando Regional Medical Center, Orlando, FL, USA.
BACKGROUND Cardiac tumors are divided into 2 categories: primary, originating from the heart, and metastatic, which spread to the heart from a different location, with metastatic tumors representing the vast majority. Cardiac tumors, depending on the size and location, can predispose patients to arrhythmic or hemodynamic complications. We present a patient with a history of B-cell lymphoma (DLBCL) in remission for 3 years who developed acute onset congestive heart failure and complete heart block secondary to DLBCL invasion of the myocardium.

December 2024
Institute of Measurement Science, Department of Biomeasurements, Slovak Academy of Sciences, Bratislava, Slovakia.
Article Synopsis
- The study focuses on using implanted devices to aid patients with chronic heart failure by analyzing ECG signals, specifically looking at the timing of stimulation/pacing based on QRS duration.
- Researchers evaluated the autocorrelation maps from body surface potential maps of 17 patients, most of whom had left bundle branch block (LBBB), to find differences in heart rhythms compared to healthy controls.
- The results indicate that certain autocorrelation parameters could serve as additional metrics for optimizing cardiac resynchronization therapy (CRT) pacing settings, particularly for patients who respond well to treatment.

Heart and Diabetes Center North-Rhine Westphalia, University Hospital of the Ruhr University Bochum, Bad Oeynhausen, Germany.
Article Synopsis
- Utilization of ventricular assist devices (VAD) for end-stage heart failure is advanced, but there's a need for evidence-based psychosocial support interventions post-implantation.
- A study in Germany involved 140 patients, randomly assigned to an intervention or control group, to evaluate the impact of a new VAD support curriculum on various health outcomes.
- Results indicated that while primary health complications were similar across both groups, the intervention significantly reduced depression in patients and showed improvements in anxiety, quality of life, social support, and self-management for those receiving the VAD intervention.

Department of Anesthesiology, First Affiliated Hospital of Gannan Medical University, Ganzhou, Jiangxi, People's Republic of China.
Article Synopsis
- The study investigates the effectiveness of a combination of suprainguinal fascia iliaca compartment block (SFICB) and sciatic nerve block (SNB) on pain relief in patients undergoing total hip arthroplasty (THA) compared to general anesthesia alone.
- Eighty-seven patients were divided into three groups to measure postoperative pain levels using a Numeric Rating Scale (NRS) and other outcomes like heart rate and opioid consumption.
- Results showed that the combined analgesic methods (SFICB and SNB) significantly reduced pain scores and opioid usage while also lowering inflammatory markers compared to general anesthesia alone, suggesting a better overall pain management approach.

Department of Medicine, Western University, London, ON N6A 5W9, Canada.
Article Synopsis
- Tricuspid regurgitation (TR) is a common issue after heart transplantation, and a new treatment called transcatheter tricuspid valve replacement (TTVR) has emerged, although it comes with risks.
- A 46-year-old woman who underwent a heart transplant developed severe TR, had a TTVR procedure, but later suffered from cardiogenic shock and sudden cardiac death, linked to complications in the area of her heart's electrical conduction system.
- This case highlights the dangers of TTVR in heart transplant patients, emphasizing the need for close monitoring due to the potential for serious heart rhythm issues like complete heart block.
Functional block in the initiation and maintenance of common flutter: detailed electrophysiological study and electro-anatomical mapping.
Front Cardiovasc Med
November 2024
Department of Cardiac Pacing and Electrophysiology, Hopital Cardiologique du Haut-Leveque, Bordeaux University Hospital (CHU), Bordeaux, France.
Article Synopsis
- The exact causes of common atrial flutter are not fully understood, particularly regarding arrhythmia triggers and the impact of slow-conducting heart tissue.
- A detailed electrophysiological study was conducted on a patient to investigate how this arrhythmia starts and is maintained, utilizing techniques like electro-anatomical mapping.
- The study found that common atrial flutter begins with a unidirectional conduction block at the septal cavo-tricuspid isthmus, resulting in a counter-clockwise activation pattern and stabilization near specific heart regions, without any slowing of conduction.

CineECG Repolarization Gradients Predict Acute Hemodynamic Response in CRT Patients.
J Cardiovasc Electrophysiol
December 2024
Department of Cardiology, Institute for Clinical and Experimental Medicine, Prague, Czech Republic.
Article Synopsis
- - The study investigates the effectiveness of a new ECG technique called CineECG, which visualizes heart electrical activity, in improving cardiac resynchronization therapy (CRT) for patients who don't respond well to standard treatments.
- - Researchers analyzed CineECG data from 15 patients with heart conditions under different pacing settings and found that specific movement directions in the heart's electrical signals correlate with better immediate heart performance (measured as dP/dt max).
- - The results indicate that the direction of the ST-T segment during repolarization can predict a significant improvement in heart function during CRT, suggesting that CineECG could help optimize treatment plans for patients.

Department of Cardiology, Cardiovascular Research Institute Maastricht (CARIM), Maastricht University Medical Centre+ (MUMC+), Maastricht, The Netherlands.
Article Synopsis
- The study investigates the prevalence and impact of inter-atrial block (IAB) as an indicator of electrical dysfunction in patients with heart failure with preserved ejection fraction (HFpEF).
- It examines two groups: ambulatory HFpEF patients and those recently hospitalized, assessing their risk for adverse events like hospitalization and death.
- Findings suggest that different stages of electrical atrial dysfunction significantly predict adverse outcomes, indicating that patients without dysfunction might require less intensive management.

Department of Pediatric Cardiovascular Surgery, JCHO Kyushu Hospital, Kitakyushu, Japan.
Article Synopsis
- Ventricular septal defect (VSD) is the most common type of congenital heart disease and often requires surgical intervention.
- The VSD patch closure surgery is crucial not only for simple VSDs but also for more complex congenital heart defects like tetralogy of Fallot and complete atrioventricular septal defect.
- To ensure successful closure without complications, surgeons must have a thorough understanding of VSD anatomy and skillfully perform sutures and ligatures.
