Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

Dynamic left ventricular outflow tract obstruction due to anemia in a 71-year-old patient with sigmoid septum

, 2010
SummarySigmoid septum, although frequently observed in the elderly, has no pathophysiological significance in general. A 71-year-old woman with sigmoid septum developed acute heart failure because of a significant left ventricular outflow tract ...

Gutter Rotation Technique for Percutaneous Ipsilateral Retrieval of a Ruptured SAPIEN‐3 Balloon

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Balloon rupture during transcatheter aortic valve replacement (TAVR) with balloon‐expandable valves is a rare but potentially serious complication that may result in incomplete valve expansion, difficult device retrieval, and vascular injury.

Dynamic left ventricular outflow tract obstruction complicated with takotsubo cardiomyopathy: The acute phase of takotsubo cardiomyopathy manifests latent left ventricular outflow tract obstruction [PDF]

Journal of Cardiology Cases, 2018
Dynamic left ventricular (LV) outflow tract (LVOT) obstruction is sometimes complicated with takotsubo cardiomyopathy (TC). The present case involves a 70-year-old woman with chest discomfort. Seven years earlier, transthoracic echocardiography revealed LVOT obstruction due to a sigmoid-shaped septum.

Double Transeptal Puncture for SAPIEN M3 Transcatheter Mitral Valve Replacement: Initial Experience, Indications, and Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The SAPIEN M3 system has been recently approved for transcatheter mitral valve replacement (TMVR). The transeptal guide sheath is used to deploy the dock, which is completely released before inserting and deploying the M3 valve using the same femoral access, transeptal puncture (TSP) and guide sheath.

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.
