Background: Management of acute type A intramural hematoma (IMH) is a controversial topic, and variable treatment strategies have been reported. Upfront aortic replacement may not be necessary in all cases. The goal of our study was to evaluate clinical outcomes of patients with acute type A IMH or thrombosed false lumen (FL) treated with upfront surgery or watchful waiting.

Total aortic arch replacement with frozen elephant trunk (FET) offers surgical options for these pathologies. The Jotec E-vita Open NEO™ branched prosthesis was introduced in 2020; we sought to share our initial experience focusing on the prosthesis selection strategies, surgical techniques, anastomosis-bleeding and graft-oozing control methods, and early clinical outcomes from two Asian centers.

Method: We report a case of a 71-year-old gentleman with multiple comorbidities and symptomatic 7 cm aortic arch aneurysm who was treated with a single-stage carotid-carotid and left carotid-axillary bypass followed by zone 0 aortic arch stenting with bimodular Nexus™ stent graft.
Background: Novel clinical challenges are faced by cardiac surgeons under the coronavirus disease 2019 (COVID-19) pandemic. Amidst the uncertainties faced due to the socioeconomic and public health impact, there is little evidence surrounding COVID-19 vaccination in patients undergoing cardiac surgery. Timing of vaccination and postvaccination adverse effects are required parameters to discuss with cardiac surgical patients.

However, there is significant controversy as to whether titrating statin therapy to concrete cholesterol targets is appropriate.
Methods: A single-center retrospective analysis of 309 consecutive patients who underwent isolated coronary artery bypass graft in 2007 and 2008 was performed.
The empirical basis for self-control in Dohsa-hou as it relates to effects on cognitive processes has been explored in a few studies of the Japanese psychotherapy, but not under standardized conditions with a strong predictive theory of control. This study reports on a series of experiments with the Dual Mechanisms of Control framework to clarify the possible regulatory mechanism of Dohsa-hou by focusing on shoulder movement, a key body movement task used by practitioners across applied settings. Cognitive control was operationalized with the AX version of Continuous Performance Test (AX-CPT) paradigm for proactive control and a modified Stroop task paradigm for reactive control in a 3-arm parallel group trial study design.

Open conversion with Crawford extent 3 thoracoabdominal aortic replacement was performed successfully and the patient was discharged home without any major complications.

Excessive oozing after total arch replacement with the frozen elephant trunk technique through the fabric of the E-vita Open NEO raised concern about its early adaptation. The mechanism is speculated to be multifactorial. Our goal was to report our approach using pre-emptive BioGlue priming on the fabric against the oozing phenomenon.

Background: Coronary endarterectomy aims to improve completeness of revascularization in patients with occluded coronary vessels. The benefits of coronary endarterectomy remain uncertain. The aim of this study was to evaluate short-term surgical outcomes and factors affecting graft patency post-coronary endarterectomy.

In this population analysis, we report on the first Asian all-comers experience and outcomes who underwent thoracic endovascular aortic repair with the use of this new stent graft system.
Methods: Between May 2019 and October 2020, 21 patients with different aortic pathologies were prospectively recruited and retrospectively analyzed.
Aortic arch pathologies have been a surgical challenge, involving cerebral, visceral and myocardial protection. Innovative techniques including total arch replacement and frozen elephant trunk had evolved over last decades with promising mid-term outcomes. We evaluate our mid-term outcomes on total arch replacement with frozen elephant trunk and the role of timely second staged interventions.

Background: Patients with hypertension may develop a thoracic aortic aneurysm (TAA) that can be asymptomatic but potentially life-threatening. We sought to assess the prevalence of asymptomatic TAA among hypertensive patients with a point-of-care screening program using pocket-size mobile echocardiographic (PME) devices.
Methods: We prospectively performed transthoracic aortic ultrasound using a PME device on patients attending our hypertension clinics between June 2016 and July 2018.
Background: Coronary artery bypass grafting (CABG) is the standard of care for patients with ischemic cardiomyopathy (ICM). Despite recent evidence supporting the role of CABG, long term outcomes for patients with ICM remain poor and 10-year results post CABG in ICM patients are under-reported, especially among Asians. Uncertainty on whether CABG improves cardiac performance and survival in the long term remains.

In our study, we aim to analyze the survival outcomes in local patients with acute type A IMH and a meta-analysis on survival in type A IMH treated medically versus surgically was performed.
Methods: From 2014 to 2019, 65 patients with acute type A IMH were selected for analysis.

The Thoraflex hybrid graft has been widely used around the world to allow a single-stage treatment for multi-segment aortic pathologies. The distal stent graft component of the Thoraflex has made it exceptionally easy for endovascular second-stage procedures when compared with the floating elephant trunk. However, published reports on operative techniques for open second-stage procedures after Thoraflex are limited.
View Article and Find Full Text PDFThe Djumbodis™ dissection system was introduced as an alternative to aortic arch replacement in acute type A aortic dissection involving the arch. In our own experience, some patients with Djumbodis implantation developed distal aortic arch and descending aortic aneurysm during subsequent follow-up and required additional interventions. However, as there is a high incidence of fracture associated with the Djumbodis system, further endovascular interventions are not feasible.

The purpose of this study is to determine the effect of adding an aortic root procedure to elective aortic surgery using the ARCH international database.
Methods: The ARCH Database was queried for all elective aortic arch replacements with and without aortic root replacement using moderate hypothermic circulatory arrest and antegrade cerebral perfusion from 2000 to 2015.

The Thoraflex™ device is a composite 4-branched graft with a distal endovascular stent that allows either a one-stage treatment or an endovascular second-stage treatment of multisegment aortic pathologies. Reports on open second-stage treatment after the Thoraflex™ device implantation are sparse especially regarding the technical aspects. We described our surgical procedure of open second-stage descending thoracic aortic replacement after Thoraflex™ implantation with a special focus on the anastomosis technique to a stent graft.

Background: Thoracic endovascular aortic repair has become the preferred treatment for a variety of descending thoracic aortic pathologies. However, there are unresolved issues such as morphologic appearance of chronic dissection, persistent false lumen perfusion, and adequacy of landing zone. Enthusiasm for improving the technique of open aortic repair and perioperative management is fading.

Methods: Between 2008 and 2015, a total of 300 patients with acute Type A aortic dissection underwent emergency surgery, consisting of 271 hemiarch repairs and 29 total aortic arch replacements, using transapical cannulation and the adventitial inversion technique at a distal anastomosis. The mean follow-up periods were 31.
