Successful left coronary cusp cryoablation in an adolescent with premature ventrıcular extrasystoles-associated cardiomyopathy

Türk Kardiyoloji Derneği Arşivi, 2020
Ventricular arrhythmias arising from coronary cusps are not uncommon. However, the mapping and ablation of outflow tract ventricular arrhythmias originating from aortic cusps can be challenging.

Inadvertent severe hypercapnia during general anesthesia: drop-in oxygen saturation or electrocardiography changes; which one warns us earlier?

Ain Shams Journal of Anesthesiology, 2022
Background During general anesthesia especially when the nurse or anesthesiologist forgets to change manual to controlled mode after successful endotracheal intubation, capnography shows End-tidal Co2 above 20 mmHg after checking the place of the ...

Important tips reflected in our daily practice from the American College of Cardiology Electrophysiology Council report on premature ventricular contractions

Anatolian Journal of Cardiology, 2020
Premature ventricular contractions (PVCs) is one of the most common situations in the current cardiology practice. Although PVCs are generally benign in people without any structural heart disease, they may be associated with left ventricular dysfunction,

Differentiating origins of outflow tract ventricular arrhythmias: a comparison of three different electrocardiographic algorithms [PDF]

Brazilian Journal of Medical and Biological Research, 2016
Our objective is to evaluate the accuracy of three algorithms in differentiating the origins of outflow tract ventricular arrhythmias (OTVAs). This study involved 110 consecutive patients with OTVAs for whom a standard 12-lead surface electrocardiogram ...

Premature Ventricular Contraction-Induced Cardiomyopathy [PDF]

Circulation: Arrhythmia and Electrophysiology, 2012
Premature ventricular contractions (PVCs) are early depolarizations of the myocardium originating in the ventricle. They are often seen in association with structural heart disease and represent increased risk of sudden death,1 yet they are ubiquitous, even in the absence of identifiable heart disease.1,2 They may cause troubling and sometimes ...

Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

Advanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...
