Dual left anterior descending artery: A case report.
J Clin Imaging Sci
December 2024
Department of Cardiology, Mount Sinai West, New York, United States.
Dual left anterior descending (LAD) coronary artery is a rare anatomical variant with significant clinical implications. Recognizing this variant is crucial for accurate diagnosis and effective management, particularly in the context of revascularization strategies. We present a 71-year-old male with a history of dyspnea on exertion with baseline wall motion abnormality on a transthoracic stress echocardiography irreversible after exercise.

The dual left anterior descending (LAD) artery is a rare anatomic variant of the LAD artery that refers to the duplication of the LAD into a short and long LAD. These two vessels, differentiated based on their lengths, ultimately provide blood supply to the areas normally covered by the LAD. In this case report, we describe an unusual case of a type IV dual LAD system with an additional finding of a separate origin for the short LAD and left circumflex (LCx) artery.

Atypical atrial flutter (AFL) can be challenging to ablate, especially when involving dual-loop re-entry. We sought to assess the electroanatomical characteristics of single- and dual-loop AFLs in patients undergoing catheter ablation. We analyzed 25 non-cavotricuspid isthmus-dependent macro-re-entrant AFL in 19 consecutive patients.

August 2024
Otolaryngology-Head & Neck Surgery, Harborview Medical Center, Seattle, Washington, United States.
Current transnasal endoscopic techniques for sinus and skull base surgery use a single endoscope to provide visualization from one perspective curtailing depth perception and compromising visualization of the instrument-target interface. The view can be blocked by instruments, and collisions between instruments often occur. The objective of this study was to investigate the use of multiportal retrograde endoscopy to provide more accurate manipulation of the surgical target.

Department of Cardiology, The First Hospital of China Medical University, Shenyang, China.
Background: Previous studies have shown the importance of achieving commissural alignment during transcatheter aortic valve replacement (TAVR). However, the anatomical spatial distribution of the bilateral coronary ostia and aortic valve commissures relative to the aortic arch is still unknown. This study aimed to evaluate this anatomical relationship.
