Prospective Cohort Study for Evaluating the Safety and Efficacy of Mobile, Motorized Enhanced Extracorporeal Counterpulsation in Patients With Refractory Angina
Enhanced external counterpulsation (EECP) is a noninvasive medical device designed for patients with refractory angina, a condition in which angina symptoms persist despite adequate medical therapy or revascularization.1 Despite its class IIb recommendation for relieving refractory angina symptoms, existing EECP equipment has limited use owing to cost, noise, vibration, and fixed compression power, causing discomfort for patients.1 –3 In addition, its large size and immobility restrict its application for critically ill patients unable to use EECP equipment.

Severity of Left Ventricular Dysfunction in Patients With Tachycardia-Induced Cardiomyopathy: Impacts on Remodeling After Atrial Flutter Ablation
Tachycardia-induced cardiomyopathy (TIC) is a unique cause of nonischemic dilated cardiomyopathy, defined as reversible left ventricular (LV) systolic dysfunction resulting from a sustained fast heart rate.1 It has been reported in patients with incessant or very frequent tachyarrhythmias with an incidence ranging from 3% to 50%, depending on the arrhythmia type and population.2 –6 Although atrial fibrillation is the most common and most studied tachyarrhythmia associated with arrhythmia-induced cardiomyopathy, atrial flutter is also a common etiology.

Long-Term Survival and Quality of Life Following Transcatheter Aortic Valve Replacement in Nonagenarians
Transcatheter aortic valve replacement (TAVR) has emerged as a successful treatment option for severe aortic stenosis. However, the long-term outcomes of TAVR in nonagenarians is lacking. We aimed to examine the long-term mortality and quality of life in nonagenarians after TAVR. This is a multicenter, retrospective analysis on patients with severe aortic stenosis who underwent TAVR. Patients were divided into 2 groups: nonagenarians (age ≥90 years) and age (Source: The American Journal of Cardiology)

Navigating the Complex Landscape of Atrial Functional Mitral Regurgitation: Insights, Challenges, and Emerging Interventions
Functional or secondary mitral valve regurgitation occurs as a consequence of abnormalities in left-sided cardiac geometry and function, in the setting of structurally normal mitral valve leaflets and chordal apparatus. It is frequently associated with left ventricular enlargement or regional dysfunction causing mitral leaflet tethering and annular dilatation, as seen in dilated cardiomyopathy or ischemic heart disease. Atrial functional mitral regurgitation (AFMR) has sparked increasing interest in recent years and is characterized by left atrial and mitral annular dilatation despite normal left ventricular size and systo...

Acute Hemodynamic Compromise After Transcatheter Aortic Valve Replacement Due to Dynamic Left Ventricle Obstruction: A Systematic Review
Acute hemodynamic compromise after transcatheter aortic valve replacement (TAVR) because of dynamic left ventricle (LV) obstruction (LVO), also known as suicide LV, is an infrequent but severe complication of TAVR that is poorly defined in previous studies. Understanding this complication is essential for its prompt diagnosis and optimal treatment. We conducted a systematic literature review using PubMed, Embase, Web of Science, and Medline databases for studies describing acute hemodynamic compromise after TAVR because of dynamic LVO or suicide LV.
