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 ...

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 ...

Right ventricular systolic function and cardiac resynchronization therapy

Cardiology Plus, 2019
Objectives: The aim of this study was to investigate the influence of right ventricular (RV) dysfunction on the response to cardiac resynchronization therapy (CRT) and the impact of CRT on RV function in a beagle model of heart failure (HF).

Coronary angiography of the ex‐situ beating donor heart in a portable organ care system

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1252-1260, December 1, 2022., 2022
Abstract Objectives To determine safety and feasibility of ex‐situ coronary angiography. Background To cater for the perpetually growing demand for heart donors, interest in donation following circulatory death (DCD) has been rekindled. Further pursuit of donor pool expansion has led to eligibility extension to “marginal” donors who are at higher risk ...

Underweight and obesity are related to higher mortality in patients undergoing coronary angiography: The KARDIO invasive cardiology register study

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1242-1251, December 1, 2022., 2022
Abstract Background In patients with some cardiovascular disease conditions, slightly elevated body mass index (BMI) is associated with a lower mortality risk (termed “obesity paradox”). It is uncertain, however, if this obesity paradox exists in patients who have had invasive cardiology procedures.

Aortic root movement correlation with the function of the left ventricle

Scientific Reports, 2021
Echocardiographic assessment of systolic and diastolic function of the heart is often limited by image quality. However, the aortic root is well visualized in most patients.

Prognostic value of mitral annular systolic plane excursion and tricuspid annular plane systolic excursion in cats with hypertrophic cardiomyopathy [PDF]

, 2018
Hypertrophic cardiomyopathy (HCM) has a variable prognosis; left atrial size, presence of clinical signs and left ventricular systolic function have been shown to predict outcomes.

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.
