“…Loss of atrial kick and possible tachycardiomyopathy are other factors that may result in lower EF and have been found to be responsible for worse hemodynamic status and increased mortality. 15 Accordingly, the ratio of Killip class 3 and 4 patients at admission was higher in the AF group in our study.…”

Aim: The prevalence of atrial fibrillation (AF) in patients with myocardial infarction (MI) ranges widely and has been reported to be as high as 21%. However, the demographic, clinical, and angiographic characteristics of AF patients with de novo MI is unclear. The aim of this study was to investigate the prevalence of patients presenting with de novo MI with AF. Methods: The study was performed as a sub-study of the MINOCA-TR (Myocardial Infarction with Non-obstructive Coronary Arteries in Turkish Population) Registry, a multicenter, cross-sectional, observational, all-comer registry. MI patients without a known history of stable coronary artery disease and/or prior coronary revascularization were enrolled in the study. Patients were divided into AF and Non-AF groups according to their presenting cardiac rhythm. Results: A total of 1793 patients were screened and 1626 were included in the study. Mean age was 61.5 (12.5) years. 70.7% of patients were men. Prevalence of AF was 3.1% (51 patients). AF patients were older [73.4 (9.4) vs. 61.0 (12.4) years, p<0.001] than non-AF patients. The proportion of women to men in the AF group was also higher than in the non-AF group (43.1% vs. 28.7%, p=0.027). Dramatically, the minority of patients were previously diagnosed with AF (14 patients, 27.4%) and only 1 out of every 5 AF patients (10 patients, 19.6%) was using oral anticoagulants (OAC). Conclusions: AF prevalence in patients presenting with de novo MI was lower than reported in previous studies. The majority of AF patients did not have any knowledge of their arrhythmia and were not undergoing OAC therapy at admission, emphasizing the vital role of successful diagnostic strategies, patient education, and implementations for guideline adaptation.

“…In early diastole, nearly 70–80% of the LV end diastolic volume (EDV) will be passively filled. Late diastole, which is driven by the contraction of the left atrium (LA) and known as the “atrial kick,” contributes ∼20–30% of the EDV 4 . Therefore, characterization of LV motion/deformation patterns in late diastole by MRI could be useful for the assessment of LVDD; however, data are lacking because some cardiac MRI techniques for tracking myocardial movement, such as tagging, have difficulties in depicting LV relaxation at the late period of a cardiac cycle because of T 1 recovery 5,6 …”

Background Cardiac MRI is an emerging modality for evaluating left ventricular (LV) diastolic dysfunction (LVDD), a pathological condition that is prevalent in aging populations. However, there is a lack of reports of MRI‐derived LV diastolic properties in late diastole. Purpose To test the hypothesis that cine MRI‐derived motion/deformation indices can be used to characterize age‐related changes on LV relaxation patterns in late diastole. Study Type Retrospective. Population In all, 412 participants (72.5 ± 4.6 years old, range 65–84) without a documented history of cardiovascular diseases. Field Strength/Sequence Balanced steady‐state free precession(bSSFP) acquired at 1.5T. Assessment Participants were divided into younger (65–74 years old, n = 275) and older (75–84 years old, n = 137) groups. Status of diabetes mellitus (DM), hypertension (HTN), and lipid disorders were recorded for each participant. Cine MRI datasets were analyzed by using heart deformation analysis (HDA). LV motion/deformation indices (displacement, velocity, strain, and strain rate) were measured through 22 phases within a cardiac cycle. Statistical Tests The prevalence of traditional cardiovascular risk conditions, LV ejection fraction (LVEF), peak LV regional displacement, velocity, and strain rates at early and late diastole were compared between two participant groups using chi‐square tests or t‐tests. Results Older participants had a significantly lower peak early radial displacement (0.797 ± 0.249 cm vs. 0.876 ± 0.286 cm), radial velocity (19.3 ± 6.3 mm/s vs. 17.5 ± 5.2 mm/s), and circumferential strain rate (64.6 ± 15.7%/s vs. 70.1 ± 17%/s) but a higher peak late circumferential strain rate (69.8 ± 16.3 %/s vs. 66 ± 15.8 %/s) than their younger counterparts. Data Conclusion Cine MRI can be used to characterize age‐related LV relaxation patterns in late diastole. Level of Evidence 3. Technical Efficacy Stage 1.

“…During tachycardia, the ventricular diastole period is reduced leading to increased dependence of the ventricular filling on the atrial kick. Patients with increased ventricular stiffness and decreased relaxation function (ventricular diastolic dysfunction) have decreased rapid filling and early diastole and become more dependent on atrial kick [ 18 ]. Most patients with AS show left ventricular hypertrophy, impaired relaxation, and reduced left ventricular capacity.…”

Rapid ventricular pacing (RVP) is commonly employed during transcatheter aortic valve replacement (TAVR); however, frequent TAVR is associated with worse prognoses. The retrograde INOUE-BALLOON® (IB) allows balloon aortic valvuloplasty (BAV) without RVP. The aim of this study was to evaluate the feasibility of retrograde IB for TAVR preparation. The study population included 178 consecutive patients (mean age, 84 ± 5 years; male, 47%) who underwent retrograde BAV before prosthetic valve replacement via the transfemoral approach. Patients were divided into a retrograde IB group without RVP (n = 74) and a conventional balloon (CB) group with RVP (n = 104). The primary endpoint was prolonged hypotension after BAV (reduced systolic pressure < 80 mmHg for over 1 min or vasopressor drug requirement). The incidence of prolonged hypotension after BAV was significantly lower in the IB group compared with the CB group (4% vs. 16%, p = 0.011). Balloons were able to penetrate and expand the aortic valve in both groups. RVP was used less for total TAVR in the IB group compared with the CB group. The aortic valve area-index after BAV was not significantly different between the two groups (0.72 ± 0.14 cm2/m2 vs. 0.71 ± 0.12 cm2/m2; p = 0.856). Multivariate analysis demonstrated that IB use was associated with avoidance of prolonged hypotension (OR, 0.27 [0.059–0.952]; p = 0.041). In conclusion, BAV using retrograde IB without RVP is both safe and feasible. More stable hemodynamics were achieved using retrograde IB by avoiding RVP during TAVR.
