Case Report: Mavacamten in mid-ventricular and apical hypertrophic cardiomyopathy—a case of targeted therapy beyond left ventricular outflow tract obstruction

Frontiers in Medicine
BackgroundMavacamten targets cardiac myosin ATPase, reducing the formation of actin-myosin cross-bridges, which alleviates excessive myocardial contraction and improves diastolic function.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Impact of VA-ECMO on Dynamic LV Outflow Obstruction After Transcatheter Aortic Valve Replacement

JACC: Case Reports
Dynamic left ventricular outflow obstruction is a rare but severe complication of transcatheter aortic valve replacement. It presents as a paradoxical hemodynamic collapse after relieving the left ventricular afterload.

Transient dynamic left ventricular outflow tract obstruction

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017
Dynamic left ventricular outflow (LVOT) obstruction has been classically described in patients with hypertrophic cardiomyopathy (HCM). The hypertrophy of the basal septum and systolic anterior motion of the mitral valve leaflet (SAM) cause dynamic LVOT ...

Left ventricular outflow tract obstruction after mitral valve replacement

, 1997
We describe a patient with left ventricular outflow tract obstruction after mitral valve replacement preserving the anterior subvalvular apparatus. Postoperative transesophageal echocardiography demonstrated systolic narrowing of the left ventricular ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Metastasizing Leiomyoma Obstructing the Right Ventricular Outflow Tract

Annals of Cardiac Anaesthesia, 2020
A very loud systolic murmur was identified during a pre-operative evaluation of a 51-year-old woman for an elective hysterectomy. The TTE showed a 4.7 cm intracardiac mass obstructing the RVOT. The patient was scheduled instead for resection of the mass.

Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair

Advanced Science, EarlyView.
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.
