Close Proximity of Left Anterior Descending Artery to the Right Ventricular Lead Apparently Implanted into the Mid-septum

Indian Pacing and Electrophysiology Journal, 2014
Right ventricular (RV) mid-septal pacing should have fewer negative effects on left ventricular function compared to apical pacing. However, targeting the mid-septum may be technically challenging since it is usually done with two-dimensional fluoroscopy.

Heart rate as a marker of relapse during withdrawal of therapy in recovered dilated cardiomyopathy [PDF]

, 2021
Objectives: The objective of this study was to determine the relationship between heart rate and relapse among patients in the TRED-HF (Therapy withdrawal in REcovered Dilated cardiomyopathy trial). Background: Understanding markers and mechanisms

Perfusion of the interventricular septum during ventilation with positive end-expiratory pressure (PEEP) [PDF]

, 1991
Objective: To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. Design: Animal study. Animals: Anesthetized, closed chest dogs (n = 8).

Persistent High Grade Flurodeoxyglucose Uptake in Lipomatous Hypertrophy of the Interatrial Septum on Dual Time Point Imaging and with Ambient Warming

World Journal of Nuclear Medicine, 2014
Lipomatous hypertrophy of the interatrial septum (LHIS) is a relatively uncommon disorder of the heart characterized by benign fatty infiltration of the interatrial septum that usually spares the fossa ovalis.

The Interventricular Septum Is Biomechanically Distinct from the Ventricular Free Walls

Bioengineering, 2021
The interventricular septum contributes to the pumping function of both ventricles. However, unlike the ventricular wall, its mechanical behavior remains largely unknown.

Predictors of the left ventricular dysfunction induced by ventricular arrhythmia

Zaporožskij Medicinskij Žurnal, 2016
The most powerful predictor of life-threatening arrhythmia risk is a combination of low heart rate variability with low ejection fraction (EF) of the left ventricle. Aim.

What Is the Hypoplastic Left Heart Syndrome?

Journal of Cardiovascular Development and Disease, 2023
As yet, there is no agreed definition for the so-called “hypoplastic left heart syndrome”. Even its origin remains contentious. Noonan and Nadas, who as far as we can establish first grouped together patients as belonging to a “syndrome” in 1958 ...

Epicardial deployment of right ventricular disk during perventricular device closure in a child with apical muscular ventricular septal defect

Annals of Pediatric Cardiology, 2013
We report a successful perventricular closure of an apical muscular ventricular septal defect (mVSD) by a modified technique. An eight-month-old infant, weighing 6.5 kilograms, presented with refractory heart failure.

Fetal cardiac interventions: clinical and experimental research

Advances in Interventional Cardiology, 2016
Fetal cardiac interventions for congenital heart diseases may alleviate heart dysfunction, prevent them evolving into hypoplastic left heart syndrome, achieve biventricular outcome and improve fetal survival.
