The Role of Electrophysiologic Study in Device Selection for Leadless Atrial Pacing [PDF]
Texas Heart Institute JournalThe AVEIR DR (Abbott Medical) was the first dual-chamber leadless pacing system approved by the US Food and Drug Administration. Many patients with sinus node dysfunction have physiologically normal atrioventricular conduction, so an atrial-only pacing ...

Clinical Anatomy, EarlyView.ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

The anatomy of interatrial communications - what does the interventionist need to know? [PDF]
, 2000 Increasingly, the interventional cardiologist is seeking to close interatrial communications by inserting devices by means of catheterisation. So as to optimise these procedures, it is adavantageous to have a firm grasp of the anatomy of the normal ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.

Ionic basis of a differential effect of adenosine on refractoriness in rabbit AV nodal and atrial isolated myocytes [PDF]
, 1999 Methods: The whole cell patch clamp technique was used to record action potentials and ion currents in AV nodal and left atrial myocytes isolated enzymatically from rabbit hearts.

Atrioventricular Reciprocating Tachycardia Mediated by Twin Atrioventricular Nodes
JACC: Clinical Electrophysiology, 2016 A 21-year-old man with univentricular and uniatrial heart came for a third attempt at ablation of recurrent supraventricular tachycardia. He had undergone a previous cardiac surgery of a Blalock–Taussig shunt, and bidirectional Glenn, and the electrophysiological study revealed an ...

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

Coexistence of Atrioventricular Nodal Reentrant Tachycardia and Idiopathic Left Ventricular Outflow-Tract Tachycardia [PDF]
, 2005 Double tachycardia is a relatively rare condition. We describe a 21 year old woman with history of frequent palpitations. In one of these episodes, she had wide complex tachycardia with right bundle branch and inferior axis morphology.
