The new MitraClip G4 device (Abbott Vascular) has been recently approved by Food and Drug Administration and is currently in limited release. A patient with a large mitral regurgitation (MR) jet but a relatively small mitral valve area (MVA) was not a surgical repair candidate nor an optimal MitraClip third-generation device candidate. Therefore, we implanted the new G4 NTW device that resulted in significant MR reduction with a 57% reduction in MVA. To our knowledge, this is the first reported clinical use of the MitraClip G4 NTW device. We find that it may provide better results than a single NTR device and less reduction in MVA than two older generation devices. Further experience is needed to optimize patient selection for the four new G4 devices available.

Heart failure due to acute mitral regurgitation (MR) may present with atypical findings on physical examination and transthoracic echocardiography (TTE), making the diagnosis difficult. A 72-year-old male was transferred to our hospital with severe cardiorespiratory failure and was initially suspected to have severe pneumonia based on the acute onset and imaging findings. The patient was eventually diagnosed with acute heart failure secondary to MR.

Recently published data suggested significantly lower pacing-induced cardiomyopathy (PICM) incidence with conduction system pacing (CSP). Because most data evaluated only the impact on the left ventricle, this study aimed to assess changes in echocardiographic parameters of morphology and function for all heart chambers in patients with baseline preserved and mid-range LVEF over a medium-term follow-up period after CSP. A total of 128 consecutive patients with LVEF > 40% and successful CSP for bradyarrhythmic indication were prospectively enrolled.

Noncardiogenic pulmonary edema after cardiac surgery is a rare but severe complication. The etiology remains poorly understood; however, the issue may arise from multiple sources. Possible causes include a significant inflammatory response or an autoimmune process.

Comparison of Alcohol Septal Ablation with Mavacamten in Obstructive Hypertrophic Cardiomyopathy.

Northwestern University, Feinberg School of Medicine, Chicago IL 60611; The Hypertrophic Cardiomyopathy Program at the Bluhm Cardiovascular Institute, Chicago IL 60611; Bluhm Cardiovascular Institute, Northwestern Memorial Hospital, Chicago IL 60611.

Background: Obstructive hypertrophic cardiomyopathy (HCM) is associated with significant morbidity due to left ventricular outflow tract (LVOT) obstruction. While alcohol septal ablation (ASA) is an established interventional treatment, mavacamten, a novel cardiac myosin inhibitor, has emerged as a non-invasive pharmacological alternative. Understanding the comparative efficacy of these two treatments is important for optimizing patient care.

Cardiovascular magnetic resonance in patients with mitral valve prolapse.

J Cardiovasc Magn Reson

December 2024

School of Biomedical Engineering and Imaging Sciences-Faculty of Life Sciences and Medicine, King's College London, London, UK.

With a prevalence of 2-3% in the general population, mitral valve prolapse (MVP) is the most common valvular heart disease. The clinical course is benign in the majority of patients, although severe mitral regurgitation, heart failure, and sudden cardiac death affect a non-negligible subset of patients. Imaging of MVP was confined to echocardiography until a few years ago when it became apparent that cardiovascular magnetic resonance (CMR) could offer comparative advantages for detecting and quantifying mitral valve abnormalities alongside tissue myocardial characterization.
