Safety of internal thoracic artery use in patients with prior mediastinal radiation undergoing coronary artery bypass grafting: a Maryland statewide propensity-matched analysis.

Background: The safety of internal thoracic artery (ITA) grafting in patients undergoing coronary artery bypass grafting (CABG) with prior mediastinal radiation remains controversial due to concerns regarding compromised sternal perfusion and radiation-induced injury. This study evaluated whether prior mediastinal radiation is associated with adverse perioperative outcomes in patients undergoing CABG with ITA grafting.

Methods: We conducted a retrospective cohort study using the Maryland Cardiac Surgery Quality Initiative (MCSQI) database.

Complex Bentall Operation: Clinical Pearls to Standardize the Procedure.

Background: A straightforward Bentall operation can be performed safely with low mortality, but some challenging cases require a more complex operation. We discuss here the steps of the Bentall procedure.

Methods: We reviewed specific scenarios, such as acute aortic dissection, native valve or prosthetic valve endocarditis, redo Bentall after aortic root replacement, calcified aortic root, and patients with prior coronary artery bypass grafting, mechanical aortic valve replacement, stentless aortic valve replacement, and prior extensive aortic arch repair with proximalization of neck vessels.

Effective orifice diameter: a new sizing parameter of surgical valve prostheses to inform valve selection.

Background: The labeled sizes of surgical valve prostheses and their discordance with the physical internal valve orifice sizes has long been a controversy in the cardiac surgery community, leading many to believe it to be a contributing factor in prosthesis-patient mismatch following valvular replacement surgery. In an attempt to address this issue, the International Organization for Standardization (ISO) 5840-2:2021 standard for surgical valve prostheses recommends that a new sizing parameter, namely, the effective orifice diameter, be provided in labeling by all manufacturers as an indicator of the true flow-passing capacity of a prosthetic valve.

Methods: The ISO Cardiac Valves Working Group conducted a multi-laboratory round-robin study to investigate whether the effective orifice diameter of a prosthetic surgical valve could be derived repeatably and reproducibly through steady forward-flow testing.

Wild-type Transthyretin Amyloid Deposition in an Ascending Aortic Aneurysm.

Amyloid deposition in aortic tissue is associated with increased stiffness. We report a patient with ascending aortic aneurysm and chronic abdominal aortic dissection who had significant wild-type transthyretin amyloid deposition on surgical pathology. The patient did not have cardiac involvement on further workup.

Valve-Sparing Aortic Root Replacement State-of-the-Art Review, Part II: Surgical Techniques.

Aortic valve disease is common, and valve-preserving operations are preferred whenever possible. Valve-sparing aortic root replacement (VSRR) has become an important tool for managing aortic root pathology in children and adults. The learning curve for this operation is challenging, but with increasing experience and technical modifications, early and late outcomes continue to improve.

Management of Adults With Anomalous Aortic Origin of the Coronary Arteries: State-of-the-Art Review.

As a result of increasing adoption of imaging screening, the number of adult patients with a diagnosis of anomalous aortic origin of the coronary arteries (AAOCA) has grown in recent years. Existing guidelines provide a framework for management and treatment, but patients with AAOCA present with a wide range of anomalies and symptoms that make general recommendations of limited applicability. In particular, a large spectrum of interventions can be used for treatment, and there is no consensus on the optimal approach to be used.

Historical Accounts of Congenital Heart Surgery.

We present historical accounts of congenital heart surgery since the early 1900s, as our specialty evolved from individual heroic efforts into an established and sophisticated surgical specialty with consistent and excellent results. We highlight colleagues and intrepid pioneers who have strived to solve seemingly insurmountable problems during this remarkable journey and celebrate continued success into the 21st century with surgical advances that have resulted in innovative operations, database inquiries, quality measures, new techniques of medical illustration, and the establishment of the Congenital Heart Surgeons' Society, which has become the leading organization dedicated to congenital heart surgery in North America.

Prevalence and Complications of Aberrant Subclavian Artery in Patients With Heritable and Nonheritable Arteriopathies.

Background: An aberrant subclavian artery (ASA) (or lusoria) is the most common congenital anomaly of the aortic arch (0.5%-2.2%; female-to-male ratio 2:1 to 3:1).

Lights, Camera, Incision: A Guide to Surgical Video Creation.

High-quality Surgical videos are an important tool for education, assessment of trainees, and dissemination of surgical techniques. However, there is significant variability in the quality of published videos. Although seemingly straightforward, surgical video creation has several common pitfalls.

Survival after operative repair of acute type A aortic dissection varies according to the presence and type of preoperative malperfusion.

Objective: Approximately one-quarter of patients with acute type A aortic dissection (TAAD) present with concomitant malperfusion of coronary arteries, mesenteric circulation, lower extremities, kidneys, brain, and/or coma. It is generally accepted that TAAD patients who present with malperfusion experience higher mortality rates than patients without, although how specific malperfusion syndromes, alone or in combination, affect mortality is not well described.

Methods: The International Registry of Acute Aortic Dissection database was queried for patients who underwent surgical repair of TAAD.

Bioprosthetic Aortic Valve Hemodynamics: Definitions, Outcomes, and Evidence Gaps: JACC State-of-the-Art Review.

A virtual workshop was organized by the Heart Valve Collaboratory to identify areas of expert consensus, areas of disagreement, and evidence gaps related to bioprosthetic aortic valve hemodynamics. Impaired functional performance of bioprosthetic aortic valve replacement is associated with adverse patient outcomes; however, this assessment is complicated by the lack of standardization for labelling, definitions, and measurement techniques, both after surgical and transcatheter valve replacement. Echocardiography remains the standard assessment methodology because of its ease of performance, widespread availability, ability to do serial measurements over time, and correlation with outcomes.

Beware of an anomalous left circumflex artery when considering aortic valve or root procedures.

Anomalous coronary arteries pose an additional challenge when contemplating surgical options for a patient with aortic valve or root pathology. We demonstrate the course of an anomalous retro-aortic left circumflex coronary artery arising from the right coronary sinus in a patient with an aortic root and ascending aortic aneurysm with severe aortic regurgitation who underwent ascending aorta and aortic valve replacements.

Early Failure of a Bioprosthetic Valve in the Pulmonary Position Causing Panic.

An asymptomatic 26-year-old woman with repaired tetralogy of Fallot and a bioprosthetic pulmonary valve presented with a large thrombosis occluding most of her right ventricular outflow tract and main pulmonary arteries. Our pulmonary embolism response team was emergently consulted, resulting in considerable discussion regarding the treatment modality given the large size and high-risk nature of the thrombosis. Ultimately, she was started on a heparin infusion until she could undergo open thrombectomy and pulmonary valve repeat replacement.

Outcomes of open and endovascular repair of Kommerell diverticulum.

Objectives: Kommerell diverticulum (KD) is a rare congenital vascular anomaly often associated with an aberrant subclavian artery (ASCA). Definitive indications for intervention remain unclear. We present open and endovascular (EV) operative outcomes in a large contemporary series and propose a management algorithm.

Preoperative dental screening prior to cardiac valve surgery and 90-day postoperative mortality.

Background: Preoperative dental screening before cardiac valve surgery is widely accepted but its required scope remains unclear. This study evaluates two preoperative dental screening (PDS) approaches, a focused approach (FocA) and a comprehensive approach (CompA), to compare postsurgical 90-day mortality.

Methods: Retrospective cohort analysis was performed on all patients who underwent valve surgery at Brigham and Women's Hospital with FocA and Massachusetts General Hospital with CompA of PDS approach from January 2009 to December 2016.

Essential information on surgical heart valve characteristics for optimal valve prosthesis selection: Expert consensus document from the European Association for Cardio-Thoracic Surgery (EACTS)-The Society of Thoracic Surgeons (STS)-American Association for Thoracic Surgery (AATS) Valve Labelling Task Force.

Comprehensive information on the characteristics of surgical heart valves (SHVs) is essential for optimal valve selection. Such information is also important in assessing SHV function after valve replacement. Despite the existing regulatory framework for SHV sizing and labelling, this information is challenging to obtain in a uniform manner for various SHVs.
