Case Report: Totally endoscopic minimally invasive mitral valve surgery during pregnancy: a case series.

A totally endoscopic minimally invasive approach is widely used for cardiac valve surgery in normal adults. However, minimally invasive cardiac surgery during pregnancy is rarely reported. In addition to traditional median thoracotomy, totally endoscopic minimally invasive approaches can now be used for pregnant patients. We describe our experience with totally endoscopic cardiac valve surgery (TECVS) during pregnancy, which is safe for both mothers and fetuses.

Del-Nido cardioplegia in cardiac surgery for elderly patients: a propensity score-matched analysis.

OBJECTIVES: To compare the safety and efficacy of del-Nido cardioplegia (DNC) with traditional 4:1 cold blood cardioplegia (CBC) in coronary artery bypass grafting and/or valve surgeries in elderly patients. METHODS: The present study is a retrospective case-series study that included 302 consecutive patients aged 70 years and over who underwent on-pump valve surgery and/or coronary artery bypass graft (CABG). DNC was administered to 90 patients and CBC to 212 patients. After propensity-score matching, 89 pairs were compared. The safety and efficacy were analyzed between the two groups. RESULTS: The DNC group had a similar mortality (3.4% vs. 5.6%, OR = 0.79, P = 0.720) and extracorporeal membrane oxygenation (ECMO) implantation rate (1.1% vs. 2.2%, OR = 0.75, P = 1.000) to the CBC group, a lower incidence of postoperative intra-aortic balloon pump (IABP) implantation (1.1% vs. 9.0%, OR = 0.54, P = 0.034) and a higher left ventricular ejection fraction (LVEF) at discharge (60 (56-64) % vs. 57 (51-62)%, P = 0.007). The estimated glomerular filtration rate (eGFR) in the DNC group was higher when the patient was transferred to the intensive care unit (79.4 (65.0-94.3) ml/min/1.73m2 vs. 77.2 (59.8-88.7) ml/min/1.73m2, P = 0.014), but no significant differences were identified after 24 h. The serum lactate values of the DNC group were significantly lower than those of the CBC group (0 h: 2.7 (2.0-3.2) vs. 3.2 (2.4-4.4), P = 0.001; 3 h: 3.2 (2.0-4.8) vs. 4.8 (2.8-6.6), P < 0.001; 6 h: 3.5 (2.2-5.4) vs. 5.8 (3.4-8.4), P < 0.001; 9 h: 3.4 (2.0-7.0) vs. 5.5 (2.9-8.3), P = 0.005). There were no differences between the two groups in respect of lactate levels at 12 h and thereafter. Postoperative creatinine kinase-MB concentrations were similar between the two groups. CONCLUSIONS: Del-Nido cardioplegia is safe and effective in elderly patients undergoing CABG and/or valve surgery.

Totally endoscopic aortic valve replacement: Techniques and early results.

Objective: To demonstrate the technical details of total endoscopic aortic valve replacement using a standard prosthesis, compare the clinical effect and safety of endoscopic aortic valve replacement and traditional aortic valve replacement. Methods: From 2020 to 2021, 60 consecutive patients underwent elective isolated aortic valve replacement (AVR). They were divided into two groups: the total endoscopic AVR group (TE-AVR group, 29 patients, nine women, aged 51.65 ± 11.79 years), and the traditional full-sternotomy group (AVR group, 31 patients, 13 women, aged 54.23 ± 12.06 years). Three working ports were adopted in the TE-AVR procedure. Results: No patient died in either group. The cardiopulmonary bypass (CPB) time and aortic cross-clamp (ACC) time in the TE-AVR group were longer than those in the AVR group (CPB time: 177.6 ± 43.2 vs. 112.1 ± 18.1 min, p < 0.001; ACC time: 118.3 ± 29.7 vs. 67.0 ± 13.2 min, p < 0.001). However, the mechanical ventilation duration (14.2 ± 9.3 vs. 24.0 ± 18.9 h, p = 0.015) and postoperative hospital stay (6.0 ± 1.7 vs. 8.0 ± 4.5 days, p = 0.025) were shorter in patients of TE-AVR group than those of AVR group. Although the ICU stay (55.1 ± 26.9 vs. 61.5 ± 44.8 h, p = 0.509) and post-operative chest drainage of the first 24 h (229.8 ± 125.0 vs. 273.2 ± 103.2 ml, p = 0.146) revealed no statistical difference, there was a decreasing trend in the TE-AVR group. Among the patients of the TE-AVR group, two patients were converted to thoracotomy because of mild to moderate paravalvular leakage identified by intraoperative transesophageal echocardiography. Conclusion: Total endoscopic aortic valve replacement is safe and feasible, with less trauma and quicker recovery.

Giant Left Ventricular Myxoma With Obstruction of the Left Ventricular Outflow Tract.

A rare case of giant left ventricular (LV) myxoma with obstruction of the left ventricular outflow tract (LVOT) was found incidentally on echocardiography in an asymptomatic 21-year-old woman. The tumor was successfully resected through transatrial septal access.

[One case of laryngeal basal cell adenoma].

A 63-year-old female patient with one year history of dyspnea intermittently, and had dyspnea aggravation for one month accompanied by coughing with blood. She was reated in our hospital in July 31, 2012. Physical examination: bilateral nasal patency, without abnormal secretions and bleeding, pharyngeal mucosa with chronic congestion, without swelling tonsil, normal laryngeal pronunciation, and without hoarseness. No bump or swollen lymph node in the neck area. There were no exception in heart, lung and stomach. Indirect laryngoscopy and fiber laryngoscopy show: One pedicled new creature in the glottis near posterior commissure, with smooth surface, located on the back end of the right vocal cord, bilateral vocal cord move well. Pathological diagnosis postoperative: laryngeal basal cell adenoma(the tubular type).
