Reliability and benefit of estimated continuous cardiac output measurement using shunt-side SpO monitor in hemodialysis.

Introduction: Estimated continuous cardiac output (esCCO) is a novel technology that enables non-invasive and continuous monitoring of cardiac output. We compared the concordance in accuracies among esCCO measurements in the shunt limb and non-shunt limb.

Methods: In this single-center prospective observational study, we include Japanese patients who underwent dialysis at our center between April 27, 2021, and February 28, 2023.

[Intractable Atrial Arrhythmia after Maze Procedure].

Maze procedure has achieved high cure rates and become the surgical golden standard for the treatment of atrial fibrillation. But, atrial arrhythmia after maze procedure is often persistent and drug-resistant. In these cases, diagnosis by electrophysiological study (EPS) and treatment by catheter ablation (ABL) are useful.

[Severe Coronary Artery Spasm after Coronary Artery Bypass Grafting;Report of a Case].

Coronary artery spasm after coronary artery bypass grafting(CABG) is rare and often fatal. There is no established treatment for perioperative coronary spasm because of the rare and not fully understood complications. We report a 67-year-old male, who experienced perioperative spasm of native coronary arteries and the left thoracic artery graft following CABG.

[Fifteen-year Follow-up of a Patient with Aortitis, Treated by Sino-tubular Junction Plication Using a Prosthetic Tube Graft for Aortic Regurgitation;Report of a Case].

A 43-year-old woman was diagnosed with aortitis associated with mild aortic regurgitation (AR) at the age of 25, which advanced to a severe grade requiring surgical treatment at age 28. Dilation of the sinotubular junction (STJ) was treated with ascending aortic replacement (Hemashield Gold 24 mm), which reduced AR from severe to mild. The patient conceived 9 years later and delivered a baby by cesarean section at 38 weeks of gestation.

Two-stage operation for isolated pulmonary valve infectious endocarditis with Candida parapsilosis.

We report a case of isolated pulmonary infectious endocarditis (IE) with Candida parapsilosis. A 66-year-old man presented with fever and cough. Echocardiography showed severe pulmonary regurgitation and vegetations on the pulmonary valves.

Clinical outcomes of medical treatment of acute type A intramural hematoma.

A retrospective study was performed in 30 patients who were treated for type A intramural hematoma from 1999 to 2008, of whom 24 were initially treated without surgical intervention. These 24 patients were followed up for 3.3 +/- 3.
