Pattern recognition of heart valve in echocardiogram using convolutional neural network / Muhammad Hanif Ahmad Nizar [PDF]

, 2017
One of the causes of heart failure is valvular heart disease which can be diagnosed using echocardiogram. However, using this machine requires a degree of skill in order to locate the heart valves. We propose the use of a trained neural network to locate

The Incidence, Severity and Clinical Consequence of Left Pulmonary Artery Stenosis After PDA Device Closure in Premature Infants Less Than 2 Kilograms

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter patent ductus arteriosus (PDA) device closure is an effective treatment option for premature infants with hemodynamically significant PDA. Left pulmonary artery (LPA) stenosis has been reported as a complication, however there is limited data on risk factors, clinical significance, and long‐term outcomes.

Fuzzy-Based Boundary Enhancement for Echocardiogram Using Local Image Characteristics

, 2006
Speckle noise and artifacts in echocardiogram may cause edges to manifest themselves in different manners. As a result, edges in echocardiogram are identified with ambiguous definitions and they pose challenges for conventional gradient approximations ...

Successful Percutaneous Retrieval of an Embolized MitraClip From the Right Subclavian Artery

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Single leaflet device attachment (SLDA) after mitral transcatheter valve edge‐to‐edge repair (M‐TEER) has been reported in up to 5% of patients. However, complete embolization of the M‐TEER device is exceedingly rare. Device retrievals in all previously reported cases were completed by vascular surgery cut down at the end. In this case, we are

Percutaneous Left Atrial Appendage Closure Using a PFO Occluder After an Incomplete Surgical Ligation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The case regards a 73‐year‐old male who was referred for consideration of percutaneous left atrial appendage closure. His left atrial appendage was ligated during prior mitral valve surgery, but was noted to be patent on a recent transesophageal echocardiography. An Amulet device was selected based on CT planning.

Early Experience With Evoque Transcatheter Tricuspid Valve Replacement in Carcinoid Heart Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Tricuspid regurgitation (TR) is nearly universal in carcinoid heart disease (CHD), but surgical replacement carries significant risk, and CHD was excluded from the landmark TRISCEND II trial. We present seven patients with CHD undergoing Evoque transcatheter tricuspid valve replacement (TTVR) at two tertiary centers.

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.

The Triple Wire Dual Angioseal Technique for Large Bore Femoral Access Closure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT There is a growing need for large‐bore femoral access across cardiac interventions. This has led to a need for more widely accessible vascular closure techniques to facilitate reliable vascular closure and wider access to these interventions.
