Roof‐dependent atrial flutter with epicardial conduction pathway masked by left atrium posterior wall debulking ablation

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
The 3D map shows a scarred area in the left atrial posterior wall. The left atrial posterior area and mitral isthmus line act as obstructions in the tachycardia. Propagation apparently shows a centrifugal pattern from LA inferoseptal area (yellow arrows).

Early occurrence of heart failure hospitalization or ventricular arrhythmia re‐define the long‐term prognosis after CRT

ESC Heart Failure, EarlyView.
Abstract Aims Classifying patients as responders or non‐responders to cardiac resynchronization therapy (CRT) has been recently challenged, suggesting that preventing heart failure (HF) progression may also provide survival benefits. We assessed a novel classification based on echocardiographic left ventricular (LV) reverse remodelling and the ...

Microvolt T‐wave alternans in early repolarization syndrome associated with ventricular arrhythmias: A case report

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Microvolt T‐wave alternans (MTWA) is a marker for the development of ventricular arrhythmias (VA), but its role in early repolarization (ER) syndrome remains unknown. MTWA was detected in a 90‐second 6‐lead electrocardiogram from an ER syndrome patient. On average, MTWA was 50 μV, higher than what was observed on healthy subjects.

Endovascular treatment of inadvertent left internal mammarian artery to great cardiac vein fistula

Hellenic Journal of Cardiology, 2016
Inadvertent left internal mammarian artery to coronary sinus anastomosis is a rare complication of coronary artery by-pass graft surgery. Management of this iatrogenic complication is controversial with conservative, surgical and endovascular options ...

Combined analysis of coronary arteries and the left ventricular myocardium in cardiac CT angiography for detection of patients with functionally significant stenosis [PDF]

arXiv, 2019
Treatment of patients with obstructive coronary artery disease is guided by the functional significance of a coronary artery stenosis. Fractional flow reserve (FFR), measured during invasive coronary angiography (ICA), is considered the gold standard to define the functional significance of a coronary stenosis.

Segmentation of Coronary Artery Stenosis in X-ray Angiography using Mamba Models [PDF]

2024 14th International Conference on Computer and Knowledge Engineering (ICCKE), Mashhad, Iran, Islamic Republic of, 2024, pp. 326-331 Publisher: IEEE
Coronary artery disease stands as one of the primary contributors to global mortality rates. The automated identification of coronary artery stenosis from X-ray images plays a critical role in the diagnostic process for coronary heart disease. This task is challenging due to the complex structure of coronary arteries, intrinsic noise in X-ray images ...

Larger coronary sinus diameter predicts the need for epicardial delivery during mitral isthmus ablation.

Europace, 2011
AIMS Mitral isthmus ablation is technically challenging, often requiring both endocardial and epicardial coronary sinus (CS) ablation. Blood flow in the CS and circumflex artery may act as a 'heat sink' and reduce the efficacy of radiofrequency ablation.

Clinical characteristics and long‐term outcomes in patients with apical hypertrophic cardiomyopathy

ESC Heart Failure, EarlyView.
Abstract Aims As a special type of hypertrophic cardiomyopathy (HCM), apical HCM (ApHCM) has different clinical characteristics while its nature history and prognosis are not well recognized. We aimed to describe the characteristics and outcomes of ApHCM and identify predictors of adverse outcomes.

Computerized electrocardiogram data transformation enables effective algorithmic differentiation of wide QRS complex tachycardias

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Accurate automatic wide QRS complex tachycardia (WCT) differentiation may be accomplished through the use of novel parameters derived from computerized data of the (i) WCT electrocardiogram (ECG) alone and (ii) paired WCT and baseline ECGs. Once automated WCT differentiation models are integrated into commercially available computerized ECG ...
