D-Shaped Left Ventricle, Anatomic, and Physiologic Implications

open access: yesCase Reports in Cardiology, 2017
Right ventricular loading/pressure influences left ventricular function because the two ventricles pump in series and because they are anatomically arranged in parallel, sharing the common ventricular septum.

Embryonic Heart Development in Play-Doh

open access: yesMedEdPORTAL, 2010
This resource uses Play-Doh to sequentially illustrate (1) folding of the heart tube into a primitive heart, (2) septation of the primitive ventricles and outflow tract by the truncoconal septum, and (3) septation of the primitive atrium by the septum ...

Application of Foley balloon catheter in palliative surgery for pulmonary atresia with an intact ventricular septem, with additional cases of pulmonary atresia with ventricular septal defect and tetralogy of Fallot

open access: yesBMC Cardiovascular Disorders, 2023
Background Pulmonary atresia and tetralogy of Fallot can require palliative surgery in the neonatal period due to severe hypoxia; however, limitations of established techniques include high failure rate and need for cardiopulmonary bypass.

Echocardiographic analysis of dogs before and after surgical treatment of brachycephalic obstructive airway syndrome

open access: yesFrontiers in Veterinary Science, 2023
Brachycephalic dogs with brachycephalic obstructive airway syndrome (BOAS) are a valuable animal model for obstructive sleep apnea (OSA) in humans. Clinical signs of upper airway obstruction improve after surgical treatment of BOAS, but the impact of ...

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]

open access: yes, 2012
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...

Pulmonary atresia with intact ventricular septum

open access: yesThe Journal of Thoracic and Cardiovascular Surgery, 1986
Neonates with pulmonary atresia with intact ventricular septum are ductus dependent from birth. The initial approach in these patients is to ensure continued adequate pulmonary blood flow in anticipation of imminent spontaneous closure of the ductus.

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

open access: yes, 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).

Analysis of left ventricular behaviour in diastole by means of finite element method [PDF]

open access: yes, 1979
The human left ventricle in diastole can be modelled as a passive structure with incremental internal pressure change being considered as the load. Recent developments in engineering stress analysis provide techniques for predicting the behaviour of ...

The role of contractile dyssynchrony in pacing-induced cardiomyopathy: detailed assessment using index of contractile asymmetry

open access: yesCardiovascular Ultrasound, 2023
Aims The pathophysiological effects of chronic right ventricular pacing and the role of right ventricular lead position are not well understood. Therefore, we investigated the association between left ventricular contractile dyssynchrony and pacing ...

Ruptura del septum ventricular como complicación de un evento coronario agudo

open access: yesRevista Colombiana de Cardiología, 2017
La ruptura del septum ventricular (RSV) es una complicación mecánica infrecuente del infarto agudo de miocardio (IAM). Los principales factores de riesgo descritos son la edad avanzada, el género femenino, un primer episodio de IAM y la presencia de ...
