The Impact of Standard Ablation Strategies for Atrial Fibrillation on Cardiovascular Performance in a Four-chamber Heart Model [PDF]

arXiv, 2022
Atrial fibrillation is one of the most frequent cardiac arrhythmias in the industrialized world and ablation therapy is the method of choice for many patients. However, ablation scars alter the electrophysiological activation and the mechanical behavior of the affected atria.

Diastolic Dysfunction and the New Recommendations for Echocardiographic Assessment of Left Ventricular Diastolic Function: Summary of Guidelines and Novelties in Diagnosis and Grading

Journal of Diagnostic Medical Sonography, 2019
Diastolic function represents the filling property of the heart during diastole. Diastole comprises four phases: isovolumic relaxation, rapid filling, slow filling (diastasis), and active filling.

Age‐related changes in the coronary microcirculation influencing the diagnostic performance of invasive pressure‐based indices and long‐term patient prognosis

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1195-1205, December 1, 2022., 2022
Abstract Objectives Investigate age‐related changes in coronary microvascular function, its effect on hyperemic and non‐hyperemic indices of stenosis relevance, and its prognostic implications. Background Evidence assessing the effect of age on fractional flow reserve (FFR), resting mean distal intracoronary pressure/mean aortic pressure (Pd/Pa), and ...

Evaluation of left ventricular function in patients with chronic obstructive pulmonary disease with or without pulmonary hypertension

Egyptian Journal of Chest Disease and Tuberculosis, 2013
Background: Chronic obstructive pulmonary disease (COPD) is a common entity in clinical practice. Development of right ventricular hypertrophy and eventual right side heart failure is also common in such patients.

CMR for Assessment of Diastolic Function [PDF]

, 2011
Prevalence of heart failure with preserved left ventricular ejection fraction amounts to 50% of all cases with heart failure. Diagnosis assessment requires evidence of left ventricular diastolic dysfunction.

Transcatheter valve repair of tricuspid regurgitation with the PASCAL system: TriCLASP study 30‐day results

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1291-1299, December 1, 2022., 2022
Abstract Background Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery. Methods TriCLASP is a prospective, single‐arm, multicenter European post‐market clinical follow‐up study (NCT04614402) to ...
