Current Trends and Perspectives of Pressure Wire-Based Coronary Artery Bypass Grafting.

Fractional flow reserve (FFR) has been well validated as a modality for evaluating myocardial ischemia, demonstrating the superiority of FFR-guided percutaneous coronary intervention (PCI) over conventional angiography-guided PCI. As a result, the strategy for coronary artery bypass grafting (CABG) is shifting toward FFR guidance. However, the advantage of FFR-guided CABG over angiography-guided CABG remains unclear.

Outcomes of 881 Consecutive Coronary Artery Bypass Graft Patients Using Heartstring Device.

Backgrounds:  One of the strategies to prevent stroke after coronary artery bypass grafting (CABG) may be the use of a device for proximal anastomosis without partial clamp of the ascending aorta.

Methods:  We retrospectively investigated early and late outcomes in consecutive 881 patients undergoing isolated CABG using Heartstring for proximal anastomosis from January 2008 to December 2022, to reveal the validity to use it. All patients underwent preoperative imaging workups to evaluate neurovascular atherosclerosis.

Flow characteristics of in-situ internal thoracic artery graft with competitive flow.

Unlabelled: We report flow characteristics of an in-situ internal thoracic artery (LITA) graft with angiographically competitive flow to the left anterior descending artery (LAD), based upon intraoperative transit-time flow measurement (TTFM) during coronary artery bypass grafting with aortic valve replacement (AVR) and during re-AVR seven years later. Although intraoperative TTFM of the graft showed lower mean flow and higher pulsatility index, suggesting inadequate anastomosis, fast Fourier transform (FFT) analysis of TTFM waveforms presented gradual waning of the amplitude, as shown in patent grafts. FFT analysis of the TTFM waveforms is helpful to judge the patency of LITA to LAD, even with competitive flow.

Effects of Fractional Flow Reserve on Coronary Artery Bypass Graft Flow to Left Anterior Descending Artery.

Background: The relationships between preoperative fractional flow reserve (FFR) values of the left anterior descending artery (LAD), FFR, and intraoperative transit time flow measurement (TTFM) variables in coronary artery bypass grafting (CABG) remain unclear.

Methods and results: We retrospectively collected data for 74 in situ left internal thoracic artery (LITA) grafts and 27 saphenous vein grafts (SVGs) to the LAD that were shown to be patent on postoperative angiography. Spearman correlation coefficients were determined between FFRand TTFM parameters of the LITA graft, as follows: maximum flow (Q), -0.

Mid-term results of distal anastomosis to the true lumen for chronic type B aortic dissection.

We investigated whether distal anastomosis to the true lumen in open surgical repair of descending aorta for chronic type B aortic dissection improved the long-term outcomes with aortic remodeling. We retrospectively reviewed 71 patients with chronic type B aortic dissection, excluding those with connective tissue disorder, from October 2001 to June 2021. The patients who underwent distal true lumen anastomosis (group T, n = 36) were compared to those with both lumens' anastomosis (group B, n = 35), regarding survival, overall and distal aortic events.

[Acute Drug Poisoning among Adolescents Using Over-the-counter Drugs: Current Status].

We discuss the current status of, and possible countermeasures for, acute drug poisoning among adolescents using OTC drugs. In the last 10 years, 36 patients aged <20 years who overdosed on OTC drugs were examined for the type of drug ingested, its active ingredients in cases of lethal dose intake, and the relevant place of purchase. Patients aged <20 years accounted for 30% of all the cases.

Two-staged surgical treatment for Kommerell diverticulum with a right aortic arch and an aberrant left subclavian artery.

Kommerell diverticulum (KD) is an aneurysm of the orifice of an aberrant subclavian artery (SCA) from the descending aorta or aortic arch. We have performed two-staged surgical strategy for the treatment of KD with right aortic arch. The first step was the bypass grafting between the left common carotid artery and the aberrant left SCA with occlusion of the distal side of KD with the plug.
