OCT in a 74-year-old woman highlights how an angiographic coronary fenestration can be acquired through calcific nodule atherosclerosis in the coronary arteries. We demonstrate how tandem anatomic and physiologic assessment can be used to diagnose, functionally evaluate, and effectively treat this rare finding.

Techniques in hybrid repair of aortic arch and thoracoabdominal aortic pathologies.

Introduction: Since the mid-1900s, techniques in the repair of aortic arch and thoracoabdominal aortic pathologies have drastically evolved. Open aortic surgical repair was once the sole option for both simple and complex aneurysmal degeneration. Today, a number of minimally invasive and hybrid approaches are now available to assist both the surgeon and patient in tackling this challenging problem.

Objective: Open surgical suprarenal aortic fenestration (OSSAF) is a technique to treat complicated type B aortic dissection (cTBAD) by resecting the intimal membrane at the level of the visceral arteries. This invasive procedure is largely abandoned since the advent of thoracic endovascular aortic repair (TEVAR) as becoming the gold standard of treating cTBAD. Identifying patterns in the late history of patients who underwent OSSAF might help better understand the evolution of TBAD.

Division of Vascular Surgery and Endovascular Therapy, Johns Hopkins University, Baltimore, Maryland.
Importance: Fenestrated and branched endovascular aortic repairs (F/BEVAR) have been adopted by many centers. However, national trends of F/BEVAR use remain unclear, particularly at sites who perform them without an US Food and Drug Adminstration (FDA)-approved investigational device exemption (IDE).
Objective: To quantify the use of F/BEVAR in the US and to determine if mortality was different at IDE vs non-IDE sites.
Evaluation of the effects of fenestration in Fontan circulation using a lumped parameter model.

Fenestration has been reported to enhance Fontan hemodynamics in several cases of Fontan circulation. However, the indication criteria for fenestration remain under discussion. To assess the effectiveness of fenestration in Fontan circulation, we conducted a theoretical analysis using a computational model of the fenestrated Fontan circulation.

Aim: Tetralogy of Fallot (TOF) is the most common cyanotic heart disease. This study aimed to demonstrate the effects of preoperative oxygen saturation on the early prognosis of TOF and identify risk factors associated with early complications.
Method: A cohort of 1,138 patients who were diagnosed and underwent one-stage surgical repair in this hospital were retrospectively included in this study.
