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 ...

Contemporary and Emerging Therapies in the Management of Refractory Angina: A Clinical Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Refractory angina (RA) represents a growing challenge in clinical cardiology, particularly in patients with obstructive coronary artery disease (CAD) who remain symptomatic despite optimal medical therapy and who are not candidates for revascularization.

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.

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).

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

Nationwide Analysis of PCI After TAVR From the Netherlands Heart Registration

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Percutaneous coronary intervention (PCI) after transcatheter aortic valve replacement (TAVR) has gained interest as concomitant coronary artery disease (CAD) is now often treated conservatively before TAVR, and TAVR is increasingly used in younger patients with longer life expectancies. Therefore, more contemporary data on PCI after

Post-operative atrial fibrillation is influenced by beta-blocker therapy but not by pre-operative atrial cellular electrophysiology [PDF]

, 2006
We investigated whether post-cardiac surgery (CS) new-onset atrial fibrillation (AF) is predicted by pre-CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta-blocker therapy may involve pre-CS pharmacological remodeling ...

Echocardiographic evaluation of the coronary sinus

Journal of the American Society of Echocardiography, 1995
The purpose of this study was to compare transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) in the evaluation of the coronary sinus and its blood flow. Forty patients were studied by TTE and TEE. The distal coronary sinus and its right atrial communication could be identified in 21 of 40 by TTE, and in all patients by TEE ...
