Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

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.

Observations on Two Previously Unreported Anatomical Factors Relating to the Esophagogastric Junction

Clinical Anatomy, EarlyView.
ABSTRACT The esophagogastric junction (EGJ) is the anatomical zone where the esophagus ends and the stomach begins. Its competence in preventing gastro‐esophageal reflux has been shown to depend on a number of factors which have been extensively investigated and widely accepted.

Case report of fatal complication of superior vena cava tear from balloon dilatation of iatrogenic superior vena cava narrowing

Annals of Cardiac Anaesthesia, 2015
The treatment options for superior vena cava (SVC) obstruction depends on the cause and severity of SVC narrowing. It ranges from conservative medical management to more elaborate endovascular and surgical repair of obstruction.

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Significance of slow vital capacity, difference between slow and forced vital capacity, ratio of FEV1/SVC with increasing age and BMI in healthy males and females

National Journal of Physiology, Pharmacy and Pharmacology
Background: The slow vital capacity (SVC), forced vital capacity (FVC) difference, and forced expiratory volume in one second (FEV1)/SVC ratio are crucial for understanding respiratory health, especially in mild airway obstruction.

Atrial tachycardia caused by a superior vena cava fibrillation with conduction block

Journal of Arrhythmia, 2012
AT caused by SVC fibrillation: Here, we report a case of a 62-year-old man with a history of incessant atrial tachycardia (AT) for several years. An electrophysiological study revealed rapid and irregular activity in the superior vena cava (SVC), but the
