Effect of Bileaflet Valve Orientation on the 3D Flow Dynamics in the Sinus of Valsalva

Journal of Biomechanical Science and Engineering, 2011
Three-dimensional (3D) evolutional behavior of flow dynamics in the aortic sinus of Valsalva was studied in vitro for finding the effects of bileaflet valve orientations in an effort to investigate possible linkages between the sinus flow and coronary ...

Multiple Coronary Arteriovenous Fistulas to the Coronary Sinus With an Unruptured Coronary Sinus Aneurysm and Restrictive Coronary Sinus Opening to the Right Atrium [PDF]

Circulation, 2009
A 37-year-old woman was transferred to our department for surgery. She had experienced intermittent chest discomfort or pain and palpitation during the last 4 years. Chest radiographs showed cardiomegaly (cardiothoracic ratio 0.63). A preoperative ECG showed normal sinus rhythm (Figure 1). Echocardiography showed marked dilatation of the coronary sinus

Pattern of initiation of monomorphic ventricular tachycardia in recorded intracardiac electrograms [PDF]

, 2005
Background: By analyzing stored intracardiac electrograms during spontaneous monomorphic ventricular tachycardia (VT), we examined the patterns of the VT initiation in a group of patients with implantable cardioverter defibrillators (ICDs).

CASE REPORT
Additional openings of the coronary sinus and associated anomalies

Archives of Medical Science, 2006
The coronary sinus normally opens into the right atrium through a single orifice. Past research studies have described various anomalies of the coronary sinus but there are fewer reports on multiple orifices of the coronary sinus.

Transfemoral Transcatheter Aortic Valve Implantation (TF‐TAVI) for Patients With Left Ventricular Assist Device (LVAD) and Aortic Regurgitation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic regurgitation (AR) develops in up to 25%−30% of patients with left ventricular assist device (LVAD). Treatment remains challenging since surgery confers significant peri‐operative risk and the lack of valvular calcification renders transfemoral transcatheter aortic valve implantation (TF‐TAVI) with non‐dedicated devices technically ...

Coronary Sinus to Left Atrial Communication

Case Reports in Medicine, 2009
Congenital coronary sinus anomalies are rare in clinical practice, partly due to the lack of symptoms. We present a case of coronary sinus anomaly causing a right-to-left intracardiac shunt in a 46 years/old African American female with a past medical ...

Left Ventricular Apical Thrombus in Apical Hypertrophic Cardiomyopathy Without Aneurysm or Arrhythmia: A Case Report

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Apical hypertrophic cardiomyopathy (ApHCM) is a rare variant of hypertrophic cardiomyopathy, typically associated with a benign course. However, complications such as ventricular arrhythmias, apical aneurysms, and thrombus formation may occur. Left ventricular (LV) thrombus is an unusual finding in ApHCM, especially in patients with preserved ...
