To determine the clinical efficacy of application of infrared energy to the beating heart as a means of creating electrical blocks, an original infrared coagulator (KIRC-119; Phomec Inc, Tokyo, Japan) was applied to the atrium of a patient with atrial fibrillation. A postoperative electrophysiologic study was performed to confirm its efficacy. The coagulator was applied epicardially to the beating heart concomitant with an on-pump beating heart coronary artery bypass graft procedure. Sinus rhythm was restored during the operation, and the electrophysiologic study revealed that a bidirectional block had been created on the right atrial appendage. The infrared coagulator may facilitate performance of the epicardial Maze procedure on the beating heart.

Division of Cardiovascular Surgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, People's Republic of China.
Background: Description of the learning curve for transapical beating heart septal myectomy (TA-BSM) helps to understand the potential for wider adaptability. The authors elaborate and examine a competency-based training assessment for TA-BSM that could serve to disseminate septal myectomy expertise.
Materials And Methods: Data on 177 consecutive patients who underwent the TA-BSM for hypertrophic obstructive cardiomyopathy (HOCM) between April 2022 and June 2023 was collected prospectively, which was registered on ClinicalTrials.

Background: Studies on rest durations during high-intensity interval training (HIIT) often compare fixed and self-selected (SS) rest allocation approaches. Frequently, the rest duration under SS conditions is unlimited, leading to inconsistent total rest durations compared to fixed rest conditions. To address this limitation, we recently compared fixed and SS rest conditions during cycling HIIT sessions, while keeping the total rest duration equivalent.

We report the case of a 72-year-old male patient who presented with a progressive aortic arch aneurysm. To reduce surgical trauma, we planned the procedure using an upper partial sternotomy with continuous cardiac perfusion and moderate hypothermia. Two vents were inserted to provide sufficient relief to the heart during perfusion.

Objective: It is well known that children who suffer from obesity and asthma may also have exercise-induced bronchospasm. Exhaled nitric oxide is an indicator of airway inflammation, and could be affected by exercise. This study looked at how exercise, which is a typical cause of acute airway obstruction, affects the levels of FeNO and in obese and asthmatic children.
