Objectives: The objective of this study was to analyze our surgical experiences with mitral valve plasty (MVP) combined with subvalvular procedures (SVPs) for functional mitral regurgitation (FMR) and to determine which preoperative factors affected clinical outcomes. Methods: This study retrospectively analyzed 33 patients who underwent MVP combined with SVPs for FMR with a left ventricular ejection fraction lower than 40% and advanced remodeled left ventricles. The mean follow-up period was 49 ± 33 months. Results: The preoperative mean right ventricular fractional area change (RVFAC) used to quantify right ventricular (RV) systolic function was 26 ± 11%. Sixteen patients (48%) had an RVFAC < 26%. One patient died during hospital stay, and nine more patients died of cardiac causes during follow-up. The 3- and 5-year rates of freedom from cardiac-related mortality were 78% and 68%, respectively. RVFAC was the significant predictor of cardiac-related mortality in a univariate analysis (risk ratio [RR] = 0.92, 95% confidence interval [CI] 0.85–0.99, p = 0.03) and demonstrated a non-significant tendency to predict cardiac-related mortality in the Cox multivariate analysis (RR = 0.94, 95% CI 0.86–1.003, p = 0.08). Continued reverse left ventricular remodeling was associated with an RVFAC ≥ 26%. At 3 years, there was also a significant difference in survival rates of cardiac-related mortality between patients with an RVFAC ≥ 26% and < 26% (94% vs. 61%; p = 0.03). Conclusions: Preoperative RV function affected left ventricular remodeling and cardiac-related mortality after MV surgery. MVP combined with SVPs for FMR provided promising results for patients without severe RV dysfunction.

An 84-year-old man, who attempted suicide, sustained injuries from nails driven into his head and the anterior thoracic region by a nail gun. A computed tomography scan revealed residual nails, along with cardiac, pulmonary, and brain injuries. The patient underwent immediate cardiac surgery and craniotomy. No apparent damage to the pericardium was observed. However, the presence of dark red changes oozing near the apex of the heart was noted. These intraoperative findings suggested the possibility of blunt cardiac injury resulting from the impact of the nail gun. While injuries to organs other than the limbs caused by a nail gun are uncommon, the severity of such injuries can vary from asymptomatic to hemodynamic failure. In cases involving thoracic wounds, not only penetrating trauma but also the occurrence of blunt cardiac injury could remarkably worsen the patientʼs overall condition. Therefore, immediate evaluation and treatment are important to save the patientʼs life.

A 73 y.o.-male underwent the arch aortic replacement for type A acute aortic dissection. Two years after operation, the computed tomography showed the rupture of thoracic aortic aneurysm and thoracic endovascular aortic repair （TEVAR） was urgently performed. Aorto-esophageal fistula （AEF） subsequently occurred at day 5 after TEVAR. Therefore, we urgently performed esophagectomy under right thoracotomy with accompanied fistulectomy, followed by omentopexy and esophageal reconstruction using gastric conduit 12 days later. To secure AEF patients, the immediate bleeding and infectious control is required. Although urgent artificial blood vessel replacement with esophagectomy with fistulectomy of AEF is desirable, the strategy of surgical intervention depends on the patient’s organ functions or systemic status. Omentopexy is an effective option to reinforce the postoperative infectious control and, additionally, the intraoperative ICG fluorescence angiography may improve to evaluate the omental vascularity by our experience.
