Zingaro A, Ahmad Z, Kholmovski E, Sakata K, Dede L, Morris A, et al.
Sci Rep . 2024 Apr; 14(1):9515. PMID: 38664464
Stroke, a major global health concern often rooted in cardiac dynamics, demands precise risk evaluation for targeted intervention. Current risk models, like the score, often lack the granularity required for...

Zingaro A, Ahmad Z, Kholmovski E, Sakata K, Dede L, Morris A, et al.
bioRxiv . 2024 Jan; PMID: 38293150
Stroke, a major global health concern often rooted in cardiac dynamics, demands precise risk evaluation for targeted intervention. Current risk models, like the CHADS-VASc score, often lack the granularity required...

Orkild B, Zenger B, Iyer K, Rupp L, Ibrahim M, Khashani A, et al.
Front Physiol . 2022 Jul; 13:908552. PMID: 35860653
Myriad disorders cause right ventricular (RV) dilation and lead to tricuspid regurgitation (TR). Because the thin-walled, flexible RV is mechanically coupled to the pulmonary circulation and the left ventricular septum,...

Morgan A, Kashani A, Zenger B, Rupp L, Perez M, Foote M, et al.
Comput Cardiol (2010) . 2021 Mar; 47. PMID: 33778088
Tricuspid regurgitation (TR) is a failure in right-sided AV valve function which, if left untreated, leads to marked cardiac shape changes and heart failure. However, the specific right ventricular shape...

Marashly Q, Gopinath C, Baher A, Acharya M, Kheirkhahan M, Hardisty B, et al.
J Am Heart Assoc . 2021 Mar; 10(7):e018924. PMID: 33759540
Background Esophageal thermal injury (ETI) is a byproduct of atrial fibrillation (AF) ablation using thermal sources. The most severe form of ETI is represented by atrioesophageal fistula, which has a...

Csecs I, Yamaguchi T, Kheirkhahan M, Czimbalmos C, Fochler F, Kholmovski E, et al.
Int J Cardiol . 2019 Dec; 305:154-160. PMID: 31874788
Introduction: Left atrial (LA) volumes are related to success of atrial fibrillation (AF) ablation, but the relation to other functional and structural parameters is less well understood. Our goal was...

Kheirkhahan M, Baher A, Goldooz M, Kholmovski E, Morris A, Csecs I, et al.
Pacing Clin Electrophysiol . 2019 Dec; 43(4):402-411. PMID: 31867751
Background: Left atrial (LA) fibrosis is thought to be a substrate for atrial fibrillation (AF) and can be quantified by late gadolinium enhancement magnetic resonance imaging (LGE-MRI). Fibrosis formation in...

Fochler F, Yamaguchi T, Kheirkahan M, Kholmovski E, Morris A, Marrouche N
Circ Arrhythm Electrophysiol . 2019 Aug; 12(8):e007174. PMID: 31422685
Background: Macroreentrant atrial tachycardia (AT) accounts for 40% to 60% of recurrent atrial arrhythmias after atrial fibrillation (AF) ablation. To describe late gadolinium enhancement magnetic resonance imaging (LGE-MRI)-detected scar-based dechanneling...

Kholmovski E, Morris A, Chelu M
Card Electrophysiol Clin . 2019 Aug; 11(3):537-549. PMID: 31400877
Left atrial fibrosis plays an important role in the pathophysiology of atrial fibrillation. Left atrial ablation is an effective and increasingly used strategy to restore and maintain sinus rhythm in...

Baher A, Kheirkhahan M, Rechenmacher S, Marashly Q, Kholmovski E, Siebermair J, et al.
JACC Clin Electrophysiol . 2018 Dec; 4(12):1583-1594. PMID: 30573123
Objectives: This study retrospectively evaluated the feasibility and esophageal thermal injury (ETI) patterns of high-power short-duration (HPSD) radiofrequency atrial fibrillation (AF) ablation. Background: ETI following AF ablation can lead to...
