Initial studies on the implanting sites of high and low ventricular septa using leadless cardiac pacemakers

Annals of Noninvasive Electrocardiology, 2023
Objective To study the safety and electrical characteristics of various implanting sites of the Micra pacemaker. Method A total of 15 patients from Beijing Anzhen Hospital, Capital Medical University, were included, who were implanted with Micra leadless

Necklace pattern left ventricular noncompaction cardiomyopathy with plethora of paradoxic septal premature ventricular complexes: A case report and literature review

Heart and Mind, 2022
We report an extremely rare case of left ventricular noncompaction (LVNC) cardiomyopathy sparing the anterior ventricular wall in an interesting “necklace” pattern in parasternal short axis view in a 76-year-old female with frequent palpitation and ...

Evolution and development of ventricular septation in the amniote heart. [PDF]

PLoS ONE, 2014
During cardiogenesis the epicardium, covering the surface of the myocardial tube, has been ascribed several functions essential for normal heart development of vertebrates from lampreys to mammals.

Ventricular septal pacing: Optimum method to position the lead

Indian Heart Journal, 2018
Adverse hemodynamics of right ventricular (RV) pacing is known for years. Several studies have revealed that adverse outcomes of RV apical pacing are directly linked to cumulative percentage of ventricular pacing.

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 ...

Premature ventricular contractions originating from the left ventricular septum: Results of Radiofrequency Catheter Ablation in twenty patients

BMC Cardiovascular Disorders, 2011
Background RFCA has been established as an effective and curative therapy for severely symptomatic PVC from the outflow tract in structurally normal hearts. However, it is unknown whether PVCs originating from the left ventricular septum, are effectively

Pattern and degree of left ventricular remodeling following a tailored surgical approach for hypertrophic obstructive cardiomyopathy. [PDF]

, 2012
Background The role of a tailored surgical approach for hypertrophic cardiomyopathy (HCM) on regional ventricular remodelling remains unknown. The aims of this study were to evaluate the pattern, extent and functional impact of regional ventricular ...

Nkx2-5 and Sarcospan genetically interact in the development of the muscular ventricular septum of the heart [PDF]

, 2017
The muscular ventricular septum separates the flow of oxygenated and de-oxygenated blood in air-breathing vertebrates. Defects within it, termed muscular ventricular septal defects (VSDs), are common, yet less is known about how they arise than rarer ...

Sinus of Valsalva Aneurysm Dissecting into Interventricular Septum Compressing RVOT [PDF]

Journal of Clinical and Diagnostic Research, 2018
Aneurysm of sinus of valsalva is a rare disorder. Rupture of sinus of valsalva into the right atria, right ventricle and the left ventricle is more commonly seen.

Will the real ventricular architecture please stand up? [PDF]

, 2017
Ventricular twisting, essential for cardiac function, is attributed to the contraction of myocardial helical fibers. The exact relationship between ventricular anatomy and function remains to be determined, but one commonly used explanatory model is the ...
