Background: Minimally invasive mitral valve repair has been proven to be a safe alternative to open sternotomy and may be accomplished through classic endoscopic and robotic endoscopic approaches. Outcomes across different minimally invasive techniques have been insufficiently described. We compare early and late clinical outcomes across matched patients undergoing robotic endoscopic and classic endoscopic repair. Methods: From 2011 to 2020, 786 patients underwent minimally invasive mitral surgery, from which we were able to generate 124 matched patients (62 patients in each cohort). Clinical results were then compared between the two matched populations. Survival analysis was used to compare freedom from mortality to 10 years among matched classic endoscopic and robotic endoscopic mitral valve repair cohorts and to calculate freedom from moderate or severe mitral insufficiency at latest follow-up. Histograms of cardiopulmonary bypass (CPB) and aortic cross-clamp times were constructed, and mean bypass and cross-clamp times were compared between classic endoscopic and robotic endoscopic cohorts. Results: There was no difference in early or late mortality at 10 years in either cohort. Freedom from moderate or severe mitral regurgitation or mitral valve replacement at last echocardiogram was 86.4% vs. 73.5% at 10 years, P=0.97. Patients undergoing robotic endoscopic mitral repair had a significantly longer CPB run when compared to the classic endoscopic cohort, with 148 min of CPB in the robotic endoscopic cohort compared to 133 min in the classic endoscopic group, P=0.03. Overall post-operative length of stay was not statistically significant between the robotic endoscopic and classic endoscopic groups, 6.3±0.5 and 6.0±0.3 days, respectively. No patients in either cohort developed renal failure or wound infection. The classic endoscopic group had a slightly higher risk of prolonged ventilation when compared to the robotic endoscopic group, with three classic endoscopic patients remaining intubated >8 hours post-operatively, compared to a single patient in the robotic endoscopic group. There were no unplanned reoperations in either group. Rates of postoperative stroke were comparable between groups (three in the classic endoscopic cohort, and two in the robotic endoscopic cohort). Conclusions: Index mitral valve surgery via a classic endoscopic approach yields similar clinical outcomes when compared to robotic endoscopic surgery. We demonstrate that both classic endoscopic and robotic endoscopic approaches allow repair of degenerative mitral valves with excellent short- and medium-term outcomes in a tertiary referral center.

Obesity is a global concern, closely allied with somatic and psychosomatic disorders. Herbal drugs are available in modern medicine to treat obesity. Garcinia camobogia being used by so many people trying to lose weight produces various systemic side effects. The study was conducted to assess its effect on anxiety, sociability, and dopamine turnover in male mice. Twenty-one male Swiss albino mice of either were divided into three groups with seven mice in each group. Control group was given distilled water (0.5 ml p.o.) and the other two groups received Garcinia cambogia extract at two different doses, a low and a higher dose (100 mg/kg and 500 mg/kg. p.o.) Each animal received a single oral dose daily, which was administered using an oral gavage for fourteen consecutive days. Effect of test drugs on anxiety was evaluated using open field test. Sociability and social novelty were evaluated using three chambers test. Results (mean ± SD) were analyzed using one-way ANOVA test followed by Tukey’s test. Garcinia cambogia extract significantly increased the time spent in the corners in the open field test, significantly reduced sociability and social novelty in the three-chamber test, significantly reduced dopamine turnover in the brain with a significant decrease in dopamine metabolite homovanillic acid (HVA) and increased D₂ receptor expression in ventral tegmental area. Garcinia cambogia extract have significant anxiogenic effect along with reduced sociability and social novelty in male mice. Moreover, these effects could be related to the altered dopamine turnover and D₂ receptor expression in mice brain. Article Highlights: Chronic used of alcoholic extract of Garcinia campbogia lead to a significant increase in anxiety that was manifested by the reduced time in the center zone and increased immobility in the open field test. Garcinia camobogia chronic administration has a profound impact on sociability and social novelty with a significant decrease in both behavioral patterns compared to the control group. These effects could be attributed to the noticed change in the dopamine turnover in the brain with a significant decrease in dopamine metabolite (HVA) and an upward expression of D2 receptors in return.

There has been renewed interest in the Ross procedure in young patients with aortic valve disease. We describe the details and results of a systematic strategy to launch a new Ross program. Our department developed a multidisciplinary educational program that involved all practitioners involved in the care of potential Ross patients. A core group of surgeons underwent extensive hands-on technical preparation. Selection of patients was reviewed by a multidisciplinary team. Patient characteristics, operative details, and postoperative outcomes were analyzed. Between March 2021 and March 2022, 22 consecutive patients underwent Ross procedure at our institution. The mean age of the patients at time of operation was 40.4 ± 10.2 years, and most patients had no medical comorbidities (12/22). The most common indication for operation was aortic stenosis (13/22), followed by mixed aortic stenosis and aortic insufficiency (7/22). There were no deaths. Postoperatively, no patient required blood transfusion or reexploration for hemorrhage. All patients were discharged home on mean hospital day 5.9 ± 1.1. On predischarge echocardiography, there was a significant reduction in mean aortic gradients preoperatively to postoperatively (49 ± 20 mm Hg vs 4 ± 1 mm Hg; P < .01) without aortic insufficiency or a change in left or right ventricular function. We demonstrate that with multidisciplinary education and extensive hands-on surgical preparation under proctored supervision, a Ross program can be initiated safely with excellent short-term results and perioperative risk that mimics that of conventional surgical aortic valve replacement.
