Objectives: Major therapeutic cardiac procedures include open heart surgery (e.g., coronary artery bypass graft, valv/septum repairs) (OPEN), insertion/repair of pacemakers, internal defibrillators, and related devices (PACE), and percutaneous coronary intervention (PCI). The use of these procedures among patients aged > 85 years has not been well-described. Methods: Inpatient records for adults aged > 85 years were obtained from a comprehensive all-payer hospital discharge database for Florida for 2006-2011. Major cardiac procedures were identified by ICD-9-CM codes. Patient race/ethnicity (non-Hispanic White, Hispanic, non-Hispanic Black), gender, payer, principal/secondary diagnoses, and in-hospital mortality were analyzed for each procedure type. Annual procedure rates were calculated using US Census population estimates. Results: There were 2,497,573 person-years at risk for the period 2006-2011, with a total of 1,355,308 inpatient hospitalizations in this very elderly population. Medicare coverage ranged from 88% in Hispanic men (HM) to 96% in White women (WW). Procedure rates were higher in Medicare patients vs. all other payers. PACE was the most common major cardiac procedure (n=32,338), followed by PCI (n=17,046) and OPEN (n=5,916). Population rates of each procedure varied significantly by race/ethnicity and gender (see Figure for PACE rates). In 2011, the rate of PCI for White men (WM) (89 per 10,000, 95% CI 84 to 94) was 20% higher compared to HM, 70% higher compared to Black men (BM), 80% higher than WW and Black women (BW), and 130% higher than Hispanic women (HW). The open heart surgery rate for WM (41 per 10,000, 95% CI 38 to 45) was significantly higher than all other groups: 1.6 times the rate for HM, 2.9 times the rate for WW, 4.1 times the rate for HW, 8.2 times the rate for BM and 10.3 times the rate for BW. In-hospital mortality rates were 1.4% for PACE, 4.3% for PCI, and 8.2% for OPEN. Temporal trends showed declining rates for all procedures over the study period. Conclusions: Major therapeutic cardiac interventions are common among the very elderly. Greater inclusion of very elderly patients in clinical trials and outcome studies is necessary to establish the survival and quality of life benefits of these procedures for patients near the end of life.

Background/Aim. The EuroSCORE II has recently been developed with an idea to provide better accuracy in prediction of perioperative mortality in the patients who underwent open heart surgery. The aim of this study was to validate clinical performances of the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II risk stratification model in the Serbian adult cardiac surgical population undergoing open heart surgery. Methods. The Euro- SCORE II values on 10,048 consecutive patients undergoing major adult cardiac surgery from 1st January 2012 to 31st March 2017, were prospectively calculated and entered the institutional database. The discriminative power of the model was tested by calculating the area under the receiver operating characteristic curve (AUC). The calibration of the model was assessed by the Hosmer-Lemeshow (H-L) statistics and the observed to expected (O/E) mortality ratio. The patients with the EuroSCORE II values of 0.5?2.50%, > 2.50?6.50%), and > 6.50% were defined to be at low, moderate, and high perioperative risk, respectively. Results. The observed in-hospital mortality was 3.86% (388 of 10,048) and the mean predicted mortality by the Euro- SCORE II was 3.61%. The discriminatory power was very good for the entire cohort as well as for all subgroups [coronary, valve(s), combined (coronary plus valve), aortic and other] of performed cardiac procedures (all AUCs > 0.75). The H-L test confirmed good calibration only for category other cardiac procedures. The O/E mortality ratio confirmed good calibration for the whole sample [O/E ratio 1.07, 95% confidence interval (CI) 0.96?1.18] and for all subgroups of performed cardiac procedures, excluding significant underprediction of mortality for aortic surgery (O/E ratio 1.64; 95% CI 1.31?1.97). The EuroSCORE II overestimated perioperative risk in a low and underestimated perioperative risk in a high risk group, with acceptable discrimination (both AUCs = 0.72). On the contrary, the O/E mortality ratio confirmed good calibration for all three subcategories of high risk group. Conclusion. The results of our study confirmed acceptable overall performances of the EuroSCORE II risk stratification model in terms of discrimination and the accuracy of model when applied to the contemporary Serbian cardiac surgical cohort undergoing open heart surgery at our Institute.

Background: Stroke as a complication of open-heart surgery can be a cause of death and widespread disability. Objectives: This study aimed to determine the relationship between the SYNTAX Score and carotid artery stenosis and evaluate patients undergoing open-heart surgery in terms of postoperative complications and mortality in a six-month to two-year follow-up period. Methods: A cross-sectional study was conducted on 113 patients with CAD who underwent open-heart surgery at our hospital from 2016 to 2017. After collecting demographic data, the SYNTAX score, and color Doppler sonography report, the data were recorded and analyzed by SPSS22. Results: In our study, most patients were male and aged between 50 and 70 years. The mean SYNTAX score was 32.667 + 13.668 in the group with significant carotid stenosis, 33.926 + 9.387 in the group with no significant carotid stenosis, and 30.868 + 9.963 in the group without carotid stenosis. The results showed no significant relationship between carotid artery stenosis and the SYNTAX score (P = 0.512) and no significant relationship between the SYNTAX score and surgical complications (P = 0.666). Conclusions: According to the results, there is no significant relationship between the SYNTAX score and various indices related to heart disease, carotid artery stenosis, and postoperative morbidity and mortality. Thus, this index cannot be used to check and follow patients. However, further studies are needed to reach a definitive conclusion.

Cardiovascular disease (CVD) is perhaps the most significant worldwide health issue. While open-heart surgery remains the predominant treatment, significant advancements have been made in minimally invasive surgery (MIS) and minimally invasive robot-assisted (MIRA) surgery. MIRA techniques offer many advantages over open-heart procedures and have extended the capabilities of MIS. However, these benefits come at the cost of increased operating times due to time spent tying knots. The additional bypass time limits patient access and is the most significant barrier to the adoption of MIRA techniques. This research seeks to overcome this barrier by designing a device for MIRA cardiac procedures that automates the knotting of sutures. If this task can be automated while ensuring the delivery of high-quality knots, great progress can be made in transforming the field. MIRA cardiac procedures can move from novel procedures performed by a select group of surgeons on a limited pool of patients to a viable alternative available to the majority of patients with CVD. In this research we propose a design for a self-contained device that delivers a locking knot. Results suggest that consistent knots can be delivered at a time savings of 12.5% and 26.4% over manual knots for trained and untrained users of a surgical robot, respectively.

The Mean

SummaryA prospective study in 13 patients undergoing open-heart surgery with extracorporeal circulation revealed a marked decrease of the mean one-stage prothrombin time activity from 88% to 54% (p <0.005) but lesser decreases of factors I, II, V, VII and X. This apparent discrepancy was due to the appearance of an inhibitor of the extrinsic coagulation system, termed PEC (Protein after Extracorporeal Circulation). The mean plasma PEC level rose from 0.05 U/ml pre-surgery to 0.65 U/ml post-surgery (p <0.0005), and was accompanied by the appearance of additional proteins as evidenced by disc polyacrylamide gel electrophoresis of plasma fractions (p <0.0005). The observed increases of PEC, appearance of abnormal protein bands and concomitant increases of LDH and SGOT suggest that the release of an inhibitor of the coagulation system (similar or identical to PIVKA) may be due to hypoxic liver damage during extracorporeal circulation.
