Conversion to Cardiac Surgery During Elective and Urgent Transcatheter Aortic Valve Implantation: A Systematic Review and Meta‐Analysis

open access: yesCatheterization and Cardiovascular Interventions, Volume 107, Issue 1, Page 210-220, January 1, 2026.
ABSTRACT Transcatheter aortic valve implantation (TAVI) has become an established treatment for severe aortic stenosis. However, the need for unplanned conversion to cardiac surgery (CS) during TAVI remains an infrequent but critical event. It is unclear whether this risk is higher in patients undergoing urgent procedures.

Decoding the Self: Single‐Trial Prediction of Self‐Boundary Meditation States From Magnetoencephalography Recordings

open access: yesHuman Brain Mapping, Volume 47, Issue 1, January 2026.
Meditation‐induced self‐boundary dissolution can be predicted from magnetoencephalography recordings using Lempel‐Ziv complexity and oscillatory power as neural markers. We demonstrate significantly above‐chance classification of altered self‐experience on a single‐trial basis and show that it is mediated by complex activation patterns across brain ...

Deep Learning‐Based Prediction Model for Cardiac Resynchronization Therapy Responders Using Electrocardiogram Data

open access: yesJournal of Cardiovascular Electrophysiology, Volume 37, Issue 1, Page 157-164, January 2026.
ABSTRACT Background Cardiac resynchronization therapy (CRT) is an established treatment for advanced heart failure, but approximately 30% of patients fail to respond. This study aimed to develop and evaluate deep learning models using preimplantation electrocardiogram (ECG) data to predict CRT response.

[Safety rules for patients with artificial cardiac pacemaker].

open access: yesRevista da Associacao Medica Brasileira (1992), 1997
The recent progress in cardiac pacing increased the usefulness of artificial pacemakers. The initial purpose of avoiding Stokes-Adams attacks, was changed by a complex way to completely give back the physiologic response of cardiac rate and atrioventricular synchronism.

Second messenger systems underlying amine and peptide actions on cardiac muscle in the horseshoe crab, Limulus polyphemus [PDF]

open access: yes, 1989
The biochemical mechanisms by which octopamine, catecholamines and the peptide proctolin exert their actions on Limulus cardiac muscle were investigated.

[Cardiac memory in patients with permanent artificial pacemakers].

open access: yesArquivos brasileiros de cardiologia, 1992
To correlate the direction of QRS complex of paced beats and postpacing T wave, in patients with artificial pacemaker.Thirty five patients with spontaneous rhythm obtained by chest wall stimulation or by programmability of the automatic interval. It was correlated in all patients, the direction forces of QRS complexes of paced beats and postpacing T ...
