Clinical Trial
Association between renal function, diastolic dysfunction, and postoperative atrial fibrillation following cardiac surgery.
Renal dysfunction is associated with a higher rate of atrial fibrillation in clinical practice. This study investigated the associations between renal function, left ventricular (LV) diastolic dysfunction, and postoperative atrial fibrillation (POAF). ⋯ In patients undergoing cardiac surgery, decreased eGFR was associated with an increased rate of LV diastolic dysfunction with a subsequent increase in the rate of POAF.

After abdominal aortic aneurysm (AAA) repair, relatively low survival during long-term follow-up remains an unresolved issue. Stress myocardial perfusion single-photon emission computed tomography (SPECT) well predicts future mortality overall, as well as providing diagnoses of coronary artery disease. The prognostic value of myocardial SPECT findings after AAA repair, however, remains unclear. ⋯ Preoperative pharmacologic stress myocardial perfusion SPECT is a useful method to predict long-term cardiovascular mortality for patients undergoing elective AAA repair.

Although coronary vasospasm (CVS) would be one of the major causes of out-of-hospital cardiac arrest (OHCA), the characteristics of patients with cardiac arrest caused by CVS have not been clarified. ⋯ CVS is an important cause of OHCA. Because significantly different characteristics are observed between CVS patients with cardiac arrest and those without, care should be taken to diagnose CVS as the cause of cardiac arrest.

Clinical Trial
Fate of functional tricuspid regurgitation after mitral valve repair for degenerative mitral regurgitation.
The issue of whether functional tricuspid regurgitation (TR) should be repaired at the time of mitral valve surgery is controversial, and the long-term durability of tricuspid valve (TV) annuloplasty remains unknown. ⋯ Aggressive treatment with concomitant TV annuloplasty should be advocated in cases with atrial fibrillation and more than moderate TR.
