Background Aortic cross-clamp utilized during cardiac surgery facilitates motionless and bloodless surgical field. However, the duration of clamp time has an inverse effect on early post-operative recovery period. In this study, we sought to examine the predictors of aortic clamp duration and intensive care unit length of stay. Results Six hundred and nine adult patients presented for elective cardiac surgery between December 2019 and December 2020 were enrolled. The age of patients ranged from 18 to 82 years (mean 55.62 years, SD ± 12.3 years). Male/female ratio is 4.6:1. Most patients (87.2%) were planned for coronary artery bypass grafting (CABG) and 78 patients (12.8%) for single heart valve procedure. Operative time (OT) ranged from 120 to 402 min and averaged 259.4 min (SD ± 45.9 min). ACC time ranged from 15 to 159 min and averaged 50.56 min (SD ± 19.4 min). Factors associated with significantly longer ACCT were: smoking (OR = 1.89 (95% CI 1.3–2.74), p value = 0.01), respiratory disease (OR = 0.48 (95% CI 0.24–0.96), p value = 0.039), obesity (OR = 1.76 (95% CI 1.18–2.63), p value = 0.005) and AVR (OR = 2.11 (95% CI 1.17–3.83), p value = 0.013). Low cardiac output syndrome (LCOS) was observed in 19.2% of patients. Longer than average ACCT was associated with increased use of inotropes (p value p value p value p value Conclusion Aortic cross-clamping is a crucial method in cardiac surgery to achieve motionless field; however, prolongation of this method had an incremental risks for the development of low cardiac output syndrome, increased first 24 h post-operative blood loss and longer stay in the intensive care unit.

We report a case of 66-year-old female patient who presented with unstable angina and New York Heart Association Class III symptoms. Echocardiogram demonstrated wall motion abnormalities in the anterior and inferior walls. Coronary angiography demonstrated a severely diseased right coronary artery (RCA) and anomalous left main (LM) coronary artery arising from the right coronary sinus and courses posterior to the aorta and runs between the aorta and the main pulmonary artery with severe multiple atherosclerotic disease. Patient underwent successful coronary artery bypass grafting and was dismissed in good general status.

OBJECTIVE We studied the utilization of home health care (HHC) among acute myocardial infarction (AMI) patients, impact of HHC on and predictors of 30-day readmission. METHODS We queried the National Readmission Database (NRD) from 2012 to 2014identify patients with AMI discharged home with (HHC+) and without HHC (HHC-). Linkage provided in the data identified patients who had 30-day readmission, our primary end-point. The probability for each patient to receive HHC was calculated by a multivariable logistic regression. Average treatment of treated weights were derived from propensity scores. Weight-adjusted logistic regression was used to determine impact of HHC on readmission. RESULTS A total of 406 237 patients with AMI were discharged home. Patients in the HHC+ cohort (38 215 patients, 9.4%) were older (mean age 77 vs. 60 years P < 0.001), more likely women (53 vs. 26%, P < 0.001), have heart failure (5 vs. 0.5%, P < 0.001), chronic kidney disease (26 vs. 6%, P < 0.001) and diabetes (35 vs. 26%, P < 0.001). Patients readmitted within 30-days were older with higher rates of diabetes (RR = 1.4, 95% CI: 1.37-1.48) and heart failure (RR = 5.8, 95% CI: 5.5-6.2). Unadjusted 30-day readmission rates were 21 and 8% for HHC+ and HHC- patients, respectively. After adjustment, readmission was lower with HHC (21 vs. 24%, RR = 0.89, 95% CI: 0.82-0.96; P < 0.001). CONCLUSION In the United States, AMI patients receiving HHC are older and have more comorbidities; however, HHC was associated with a lower 30-day readmission rate.

Giant right coronary artery (RCA) aneurysm is a rare coronary artery pathology. We describe a 45-year-old gentleman who presented with unstable angina of recent onset. Diagnostic workup including chest computed tomography angiography and left heart catheterization demonstrated three-vessel coronary artery disease with giant proximal RCA aneurysm. In the view of the severity of the coronary artery disease and the risk of rupture associated with the giant RCA aneurysm and the clinical presentation, the patient was successfully treated by coronary artery bypass surgery. During this procedure, the RCA aneurysm was ligated at both inflow and outflow. The patient recovered well and was discharged home.

Re-admission is an important source of patient dissatisfaction and increased hospital costs. A simple calculator to determine the probability of re-admission may help guide patient dismissal planning.Using the national readmissions database (NRD), we identified admissions for isolated primary coronary artery bypass (CABG) and stratified them according to 30-day readmission. Including pre, intra and postoperative variables, we prepared a logistic regression model to determine the probability for re-admission. The model was tested for reliability with boot-strapping and 10-fold cross-validation.From 135,699 procedures, 19,355 were readmitted at least once within 30days of dismissal. Patients who were readmitted were older (67±10 vs 65 ± 10 years, p0.01), females (32% vs 24%; p0.01) and had a higher Elixhauser comorbidity score (1.5±1.4 vs 1.1±1.2; p0.01). Our final model (c- statistic=0.65) consisted of 16 pre and three postoperative factors. End-stage renal disease (OR 1.79 [1.57-2.04]) and length of stay9days (OR 1.60 [1.52-1.68]) were most prominent indicators for readmission. Compared to Medicaid beneficiaries, those with private insurance (OR 0.62 [0.57-0.68]) and Medicare (OR 0.85 [0.79-0.92]) coverage were less likely to be readmitted.Our simple 30-days CABG readmission calculator can be used as a strategic tool to help reduce readmissions after coronary artery bypass surgery.

It remains uncertain how advances in revascularization techniques, availability of new evidence, and updated guidelines have influenced the annual rates of coronary revascularization in the United States.We used the Nationwide Inpatient Sample data from 2005 to 2014 with appropriate weighting to determine national procedural volumes. To present accurately overall percutaneous coronary intervention (PCI) rates, PCI with same-day discharge numbers per year were estimated from the available literature and added to annual PCI procedures performed.Annual PCI rate declined from 353 per 100,000 adults in 2005 to 277 per 100,000 adults in 2009 (P.001) but remained stable thereafter (P = .50). Annual coronary artery bypass grafting (CABG) rate declined steadily, at a shallower slope than PCI, from 120 per 100,000 in 2005 to 93 per 100,000 in 2009 (P = .02) but remained stable thereafter (P = .60). Similar trends were seen in men and women. Both PCI and CABG rates were lower in women than men over the study period (PCI, 482 to 324/100,000 in men vs 232 to 153/100,000 in women; CABG, 172 to 118/100,000 in men vs 64 to 38/100,000 in women). Annual PCI rates were higher than CABG rates in patients of all age groups including in younger patients (age50) and octogenarians. The proportion of coronary revascularization procedures performed per insurance type remained relatively similar across the study period.Annual rates of coronary revascularization have changed significantly over time, potentially because of advances in revascularization techniques, availability of new evidence, and updated guidelines. Rates of PCI declined more steeply than CABG before plateauing but remained higher than rates of CABG across the study period.

We studied the utilization of home health care (HHC) among acute myocardial infarction (AMI) patients, impact of HHC on and predictors of 30-day readmission.We queried the National Readmission Database (NRD) from 2012 to 2014identify patients with AMI discharged home with (HHC+) and without HHC (HHC-).

Patients in the HHC+ cohort (38 215 patients, 9.4%) were older (mean age 77 vs. 60 years P0.001), more likely women (53 vs. 26%, P0.001), have heart failure (5 vs. 0.5%, P0.001), chronic kidney disease (26 vs. 6%, P0.001) and diabetes (35 vs. 26%, P0.001). Patients readmitted within 30-days were older with higher rates of diabetes (RR = 1.4, 95% CI: 1.37-1.48) and heart failure (RR = 5.8, 95% CI: 5.5-6.2). Unadjusted 30-day readmission rates were 21 and 8% for HHC+ and HHC- patients, respectively. After adjustment, readmission was lower with HHC (21 vs. 24%, RR = 0.89, 95% CI: 0.82-0.96; P0.001).In the United States, AMI patients receiving HHC are older and have more comorbidities; however, HHC was associated with a lower 30-day readmission rate.

We report a case of 66-year-old female patient who presented with unstable angina and New York Heart Association Class III symptoms. Transthoracic Echocardiogram demonstrated severe wall motion abnormalities in the anterior and inferior walls of the heart. Coronary angiography demonstrated a severely diseased right coronary artery and an anomalous left main coronary artery arising from the opposite coronary sinus and courses posterior to the aorta and runs between the aorta and the main pulmonary artery with severe multiple atherosclerotic disease. Patient underwent successful coronary artery bypass grafting and was dismissed in good general status.

OBJECTIVE To compare post-procedural outcomes of trans-catheter valve replacement (TAVR) among safety-net (SNH) and non-safety net hospitals (non-SNH). BACKGROUND SNH treat a large population of un-insured and low income patients; prior studies report worse outcome at these centers. Results of TAVR at these centers is limited. METHODS Adults undergoing TAVR at hospitals in the US participating in the National In-patient sample (NIS) database from January 2014 to December 2015 were included. A 1:1 propensity-matched cohort of patients operated at SNH and non-SNH institutions was analyzed, on the basis of 16 demographic and clinical co-variates. Main outcome was all-cause post-procedural mortality. Secondary outcomes included stroke, acute kidney injury and length of post-operative stay. RESULTS Between 2014 and 2015, 41,410 patients (mean age 80 ± 0.11 years, 46% female) underwent TAVR at 731 centers; 6,996 (16.80%) procedures were performed at SNH comprising 135/731 (18.4%) of all centers performing TAVR. SNH patients were more likely to be female (49% vs. 46%, p

Introduction: Safety-net hospitals (SNH) treat a large population of un-insured and low income patients; several prior studies report worse outcome at these centers. Trans-catheter valve replacement (TAVR) is emerging as first-line therapy for aortic stenosis irrespective of surgical risk scores. However, results of TAVR performed at these centers is limited. Objective: To determine whether post-procedural outcomes of TAVR are comparable at safety-net (SNH) and non-safety net hospitals (non-SNH). Methods: We conducted a retrospective, cohort study with propensity-matched analysis. Complex survey data from the Agency for Healthcare Quality and Research containing weighted sample of all hospital admissions nationwide was utilized for this study. Adults undergoing TAVR at US hospitals participating in the National In-patient sample (NIS) database from January 2014 - December 2015 were included. A 1:1 propensity-matched cohort of patients operated at safety-net hospitals (SNH) and non-SNH institutions was analyzed. Propensity-matching was performed on the basis of sixteen demographic and clinical confounding co-variates. Main outcome studied was all-cause post-procedural mortality. Secondary outcomes compared were stroke, acute kidney injury and length of post-operative stay. Results: Between 2014 - 2015, 41410 patients (mean age 80 +/- 0.11 years, 46% female) underwent TAVR at 731 centers nationwide; 6996 (16.80 %) procedures were performed at safety net centers. SNH comprised 135/731 (18.4%) of all centers performing TAVR. SNH patients were more likely to be female (49 % vs 46 %, p Conclusion: Post-procedural outcomes after TAVR at SNH are comparable to national outcomes. Our study provides preliminary evidence that wider adoption of TAVR may not adversely influence outcomes at SNH.

Objective: Home health care (HHC) is a support tool to transition patients after discharge and acute myocardial infarction (AMI) is a significant cause of morbidity and mortality in the U.S. However, little is known regarding the impact of HHC on AMI patients. We sought to identify predictors of readmissions among AMI patients, characteristics of those who receive HHC and investigate the association of HHC with readmission. Methods: We queried the National Readmission Database (NRD) (January 2012 - December 2014), to identify patients discharged after AMI and selected patients who were discharged home with (HHC+) and without HHC (HHC-). We reported national estimates with survey methods with weights provided in our data. After univariate exploratory analyses, we developed a regression model to identify the probability of each patient to receive HHC. From the propensity score, we calculated average treatment on the treated (ATT) weights. These ATT weights were included in the logistic regression model to determine the impact of HHC on readmission after adjusting for available clinical confounders. We considered post-weighting standardized differences Results: Between January 2012 to December 2014, 406,237 patients were treated for AMI and discharged home with or without HHC. Among these 9.4% (38,215) received HHC. HHC+ patients were older (mean age 77 ± 11 vs 60 ±12 years p Conclusion: In the United States, a small proportion of patients receive home health care after discharge post-AMI. Older, females and those with diabetes or heart failure are more likely to receive home health care. Use of home health care may be associated with lower 30-day readmission rates after AMI.

Background Elevated levels of blood lipids are considered a major modifiable risk factor for the development of cardiovascular diseases. The optimal management of dyslipidemia remains inadequate worldwide. Accordingly, there is an increasing need to evaluate the basis that health care providers are using to control dyslipidemia. Aim To evaluate the awareness of Jordanian physicians about the American College of Cardiology/American Heart Association (ACC/AHA) guidelines for dyslipidemia management. Method A written questionnaire was distributed to 250 physicians from different areas of Jordan during seven months period (from February 2018 until the end of August 2018). The target population is composed of the following categories: juniors, residents, fellows, and consultants who were recruited from private, government, and military practice settings. The validated developed questionnaire was distributed by trained medical personnel. Results A total of 207 physicians filled and handed back the questionnaire. The response rate was 82.8%. Generally, there was a difference in the level of knowledge between physicians (juniors/ residents/ consultants) while there was no difference between genders or practice settings (private or government). The current study showed that the awareness of physicians in different areas of Jordan regarding the 2013 (ACC/AHA) dyslipidemia guidelines is suboptimal. Conclusion Results indicated low levels of knowledge of 2013 ACC/AHA guidelines for the management of dyslipidemia among physicians in Jordan. Hence, multiple interventions are needed to be implemented in order to increase the level of awareness among Jordanian physicians.

Background Limited data exist studying the outcomes of the 2 minimally invasive aortic valve replacement (AVR) strategies—mini-sternotomy (AVR-st) and right anterior thoracotomy (AVR-th). We conducted an indirect meta-analysis to compare the outcomes of these minimally invasive approaches with each other and with conventional AVR (cAVR). Methods We Searched Medline, PubMed, Embase, and Web of Science in December 2017 for studies comparing AVR-st, AVR-th, and cAVR. Clinical outcomes were compared between cohorts with inverse weighted random effects modeling. Endpoints studied included hospital mortality, stroke, atrial fibrillation, cardiopulmonary bypass (CPB) time, and length of stay. Results A total of 19 studies (>10,000 pooled patients) met the inclusion criteria. Mortality (p = 0.06) and stroke (p = 0.15) were comparable between minimally invasive and conventional AVR. CPB times were longer with AVR-th versus cAVR (12.4 minutes [range, 5 to 19]; p Conclusions Minimally invasive approaches to AVR yield excellent outcomes in high-volume centers. They reduce hospital stay and incidence of postoperative atrial fibrillation, and therefore should be considered in patients undergoing AVR. The operative approach should be selected according to surgeon’s technical expertise and what is best for specific patient profile, however.

Chronic ischemic mitral valve regurgitation is a result of disturbed left ventricular geometry secondary to myocardial ischemia in the absence of intrinsic mitral valve pathology. It is a common complication after myocardial infarction, and patients who have ischemic mitral regurgitation (IMR) have a worse prognosis compared to patients who have ischemic heart disease alone, and this is directly related to the severity of IMR. Medical therapy has limited efficacy, and surgical options including various repair techniques and valve replacement had been tried with variable success. Still there is intense debate among surgeons whether to interfere with moderate degree IMR at the time of coronary artery revascularization.

Background Sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) are increasingly adopted methods to treat high-risk patients with severe aortic valve stenosis. We conducted a systematic review and meta-analysis to compare the clinical outcomes between these two recent methods to treat aortic valve disease. Methods We systematically searched multiple databases (January 2000 to October 2016) to identify original studies comparing clinical outcome between SU-AVR and TAVI. End points studied were early mortality, development of paravalvular leak, early stroke, bleeding events, and the need for pacemaker insertion. A random-effect inverse-variance weighted analysis was performed. Event rates were compared as odds ratio (OR) and 95% confidence interval (CI). Results The meta-analysis included seven observational studies comprising 617 SU-AVR and 621 TAVI patients. Early mortality was 2.5% and 5% in the SU-AVR and TAVI cohorts, respectively (OR, 0.52; 95% CI, 0.30 to 0.90; p = 0.02; I2 = 2%). Postprocedural significant paravalvular leak was much lower after SU-AVR (OR, 0.18l; 95% CI, 0.11 to 0.30; p Conclusions Our meta-analysis of observational studies demonstrates that early mortality is lower after SU-AVR than after TAVI in selected patients. The rates of stroke and pacemaker implant are comparable between procedures; however, the incidence of paravalvular leak is higher after TAVI.

The Center for Medicaid and Medicare Services penalizes hospitals with high readmission rates after coronary artery bypass grafting (CABG). Home health care (HHC) is a proven discharge support tool. We performed a propensity-matched analysis to determine impact of HHC on readmissions after CABG.We queried the National Readmissions Database (January 2012-December 2014) for patients undergoing isolated CABG discharged home with and without HHC. Primary end point was 30-day readmission. A well-balanced subset of patients with and without HHC was created with propensity matching. Weight-adjusted logistic regression was performed to determine impact of HHC on readmissions after CABG.In our study, 204,184 patients (mean age. 64 years; 22% female) were discharged home after CABG; 86,206 (42%) received HHC. Old age (66 vs 63 years; P .01), diabetes (46% vs 41%; P .001), COPD (21% vs 18%; P .01), peripheral arterial disease (14% vs 11%; P .001), and chronic kidney disease (2% vs 1.5%; P = .01) were factors associated with HHC. With nearest-neighbor 1:1 matching without replacement, we identified 66,610 patient pairs (unweighted) for further analysis. Readmission occurred in 11.1% and 12.5% of patients with and without HHC, respectively. After adjustment for 21 clinical covariates, use of HHC (odds ratio, 0.816; 95% confidence interval, 0.808-0.823) led to significantly lower readmission rates (P .001).HHC after coronary artery bypass surgery is more often provided to women, older patients, and those with diabetes mellitus, peripheral arterial disease, and chronic lung or kidney dysfunction. HHC appears to be associated with reduced rates of early readmission.

Concomitant coronary and carotid artery disease is reported in 14% patients scheduled for coronary artery bypass grafting. However, when to surgically intervene on the carotid lesion is a controversial issue. Both concomitant and staged procedures have their proponents and opponents alike. In this chapter we present our argument for a selective approach towards carotid artery screening. We also provide a synopsis of accepted management strategies for patients with concomitant carotid and coronary artery disease and outline contemporary outcomes.

BACKGROUND Valve selection in patients with end-stage renal disease (ESRD) is uncertain. We performed a systematic review and meta-analysis to compare clinical outcome in ESRD patients undergoing valve replacement. METHODS We systematically searched multiple databases (2000–October 2015) to identify original studies comparing adverse events between mechanical and biological valve replacement in ESRD patients. End-points studied were: postoperative mortality, bleeding events, need for re-operation, and late survival. A random-effect inverse-variance weighted analysis was performed; event rates are compared as odds ratio (OR and 95% confidence interval) and hazard ratios (HR) for time-to-event data. Mechanical valve and tissue valve replacement were considered as study and control cohorts, respectively. RESULTS Fifteen retrospective studies (5523 mechanical and 1600 tissue valve) were included in our meta-analysis. Early mortality was comparable (OR 1.15 [0.77; 1.72]; p = 0.49). The mean follow-up among studies ranged from 1.6–15 years. Bleeding was significantly higher after mechanical valve replacement (OR 2.55 [1.53; 4.26]; p = 0.0003). Structural valve degeneration was present in only 0.6% patients after a tissue valve replacement. Overall survival after valve replacement was poor (median 2.61 years); valve choice did not influence this outcome (pooled HR 0.87 [0.73; 1.04]; p = 0.14). CONCLUSION Operative mortality in ESRD patients is comparable between mechanical and tissue valve replacement. Major bleeding episodes are significantly higher after mechanical valve replacement but structural degeneration in tissue valves during the follow-up period is low. Based on the findings from this meta-analysis, we would recommend using tissue valves in patients with ESRD.

Hepato-renal function is a valuable predictor of success after left ventricular assist device therapy and heart transplantation. Hence, we analyzed the importance of the Model for End-stage Liver Disease excluding international normalized ratio (MELD-XI) score to outcomes after heart transplant.Adults undergoing heart transplant from the United Network for Organ Sharing (UNOS) database were identified (1994 to 2014). Individual MELD-XI scores were calculated; patients were stratified by MELD-XI quartiles (Q1 to Q4). Multivariate logistic regression and the Cox proportional hazard model were implemented to determine any association between MELD-XI scores, survival and other outcomes.From 39,711 patients undergoing OHT during the study period, MELD-XI score [median 10.7 (interquartile range 7.0 to 14.4)] was calculated for 36,005 patients (76% male and 75% white, 34% Status 1A). Higher MELD-XI scores had higher rates of pre-transplant extracorporeal membrane oxygenation, intra-aortic balloon pump, inotrope use and mechanical ventilation (p0.001 for all). Adjusted long-term mortality (median follow-up 8.1 years) was associated with MELD-XI score (hazard ratio [HR] 1.021 [1.016 to 1.026], p0.001). The highest MELD-XI quartile was associated with an HR 1.364 [1.255 to 1.482] risk of mortality compared with Q1. MELD-XI score was also associated with increased post-transplant infections (adjusted HR Q4 vs Q1: 1.364 [1.153 to 1.614], p0.001), stroke (adjusted HR Q4 vs Q1: 1.410 [1.074 to 1.852], p = 0.013), dialysis (adjusted HR Q4 vs Q1: 3.982 [3.386 to 4.683], p0.001), rejection (adjusted HR Q4 vs Q1: 1.519 [1.286 to 1.795], p = 0.003) and prolonged hospitalization (adjusted HR Q4 vs Q1: 1.635 [1.429 to 1.871], p0.001).Hepato-renal dysfunction, measured with MELD-XI score, predicts morbidity and mortality in patients undergoing orthotopic heart transplantation. Etiology of hepato-renal dysfunction should be sought and treated before heart transplantation.

Background In the early postoperative period after cardiac surgery the heart may be temporarily dysfunctional and prone to arrhythmias due to the phenomenon of myocardial stunning, vasoplegic syndrome, systemic inflammatory response syndrome (SIRS), electrolyte disturbances, operative trauma and myocardial edema. Most cases of cardiac arrest after cardiac surgery are reversible. Objective To analyse the factors that may influence the outcome of cardiac arrest after adult and pediatric cardiac surgery. Methods Retrospective analysis that included cardiac surgical procedures (886 adult and 749 pediatric patients) performed during the 18 month period of this study at Queen Alia Heart Institute/ Amman, Jordan. All cardiac arrest events were recorded and analysed. Data was collected on Utstein style templates designed for the purpose of this study. The outcome of cardiac arrest is examined as an early outcome (ROSC or lethal outcome) and late outcome (full recovery, recovery with complications, or in-hospital mortality). Factors that may influence the outcome of cardiac arrest were recorded and statistically analysed. Ethical committee approval obtained. Results The overall mortality rate was 3.3%. Cardiac arrest occurred in 114 patients (6.97%). The age of patients ranged from 5 days to 82 years and constituted 66 pediatric and 48 adult patients. Most pediatric cardiac arrests manifested as non-shockable rhythms (77%). Most in-hospital cardiac arrests occurred in the intensive care unit (86.5%). The majority of patients were mechanically ventilated at the time of occurrence of arrest (62.5% and 54.5% in adult and pediatric patients, respectively). Average time of cardiopulmonary resuscitation was 32.24 minutes. Overall, CA survival was 20% higher in the paediatric sub-group (full recovery rate of 51.5%). Neurological injury was slightly lower in pediatric than adult cardiac arrest survivals. (2% vs. 3%). Conclusion Shockable rhythms are more common in adult cardiac arrest, while non-shockable rhythms are more frequent in the pediatric sub-population. Hemodynamic monitoring, witnessed-type of cardiac arrest, non-interrupted cardiac massage, and early recognition of cardiac tamponade are the factors associated with higher rates of survival.

Cardiovascular diseases are described as disorders of heart and vessels that involve stroke and coronary heart diseases. People in the Middle East converged to complementary medicine as an economic alternative to expensive healthcare services. Crataegus monogyna Jacq. (Lindm.) Rosacea is among the most commonly used herb for the treatment of declining cardiac performance, hypertension, and arrhythmias. Previously, we had shown that Crataegus Spp. (Hawthorn) extract increased the tendency of bleeding among patients undergoing coronary artery bypass grafting. Herein, the effects of Crataegus Spp. extract on oxidative stress, cardiac and hematological parameters were evaluated in Sprague Dawley rats. Male rats were randomly assigned into four groups. Group 1 served as control while groups 2–4 served as the experimental groups and were administered extract at doses of 100, 200, and 500 mg/kg. All the doses were given orally once/day and the treatment was continued for three weeks. Hawthorn treatment resulted in a significant decrease in the liver thiobarbituric acid reactive substances level in a dose-dependent manner compared to the control (1.258 (3, 24); P < 0.0001). We found a significant increase in the cardiac antithrombin III among hawthorn treated group compared to the control (4.18 (3, 24); P < 0.0001). On the other hand, hawthorn treatment decreased significantly the liver factor-X level (0.1341 (3, 22); P < 0.0001), while no significant changes were seen in soluble-platelet endothelial cell adhesion molecule-1 (P-value = 0.0599). In conclusions, hawthorn extract possesses an antioxidant effect and blood-thinning properties. Hence, we recommend attention when using this herbal extract with other anticoagulation and/or antiplatelet drugs or undergoing major cardiac surgery.

Background We compared early adverse events and midterm survival between primary coronary artery bypass grafting (pCABG) and CABG in patients with percutaneous intervention (secondary CABG, sCABG) because data on this topic are very limited. Methods A systematic review of published literature was done to obtain original studies fulfilling the search criteria. The end points studied were early mortality, stroke, renal failure, myocardial infarction, and the need for an intra-aortic balloon pump. A random-effect inverse variance weighted analysis was performed. The results are presented as risk ratios (RR) (95% confidence interval); p Results Fourteen studies (84,983 pCABG patients and 14,775 sCABG patients) were included in the systematic review. Early mortality was lower with primary CABG (RR 1.54 [1.19–2]; p = 0.007). The incidence of myocardial infarction was also less with pCABG than with sCABG. (RR 1.46 [1.04–2.06]; p = 0.06). Patients undergoing pCABG were 14% (0% to 55%; p = 0.04). Less likely to need an intra-aortic balloon pump. Although renal failure was lower with pCABG (RR 1.254 [1.047–1.502]; p = 0.014), the stroke rates were comparable in both cohorts ( p = 0.95). Renal failure was favorable in the primary CABG cohort. Early stroke was comparable between the two cohorts ( p = 0.95). The pooled hazard ratios demonstrated comparable survival at the end of 3 years ( p = 0.36). Conclusions Patients undergoing CABG after prior percutaneous therapy have a higher incidence of myocardial infarction and mortality in the postoperative period. However, midterm survival is comparable in both cohorts.

Introduction Levosimendan is implemented in patients with low cardiac output after cardiac surgery. However, the strength of evidence is limited by randomized controlled trials enrolling a small number of patients. Hence we have conducted a systematic review to determine the role of levosimendan in adult cardiac surgery. Methods PUBMED, WoS, Cochrane database, and SCOPUS were systematically queried to identify original English language peer-reviewed literature (inception-October 2014) comparing clinical results of adult cardiac surgery between levosimendan and control.

Bilateral internal thoracic artery grafting appears to be the preferred method to achieve durable long-term coronary artery revascularization. However, data reporting the benefit of this technique in the elderly is very conflicting.We performed a systematic review of available literature (till November 2014) using multiple databases to identify studies comparing clinical events in patients undergoing coronary artery bypass grafting using either a single or double internal thoracic artery in the elderly. While early mortality was the primary end-point of inclusion, other adverse events compared were sternal wound infection (deep and superficial), stroke and peri-operative myocardial infarction. Individual and pooled odd's ratios were calculated using the Mantel-Haenzel method (random effect model); sensitivity analysis was performed. Results are presented using 95% confidence intervals.Nine retrospective studies (4479 BITA, 7733 LITA patients) fulfilled search criteria. Deep sternal wound infection was significantly higher after BITA harvest [OR 1.86 (1.3-2.5); I(2) = 0%; p 0.01]. Early mortality (BITA 3.6% vs SITA 3.1%; p = 0.86), stroke [OR 0.7(0.4-1.1); p = 0.1], and peri-operative myocardial infarction (BITA 4.3% vs SITA 2.3%; p = 0.1) were comparable in both cohorts. Long-term survival favored the BITA cohort in two propensity matched studies.The incidence of deep sternal wound infection may be significantly higher after the harvest of both internal thoracic arteries in the elderly. While other post-operative adverse events are comparable, data regarding the long-term survival advantage in this cohort is conflicting. Hence, the use of both internal thoracic arteries in this age group needs to be invidualized.

Intravenous drug use (IVDU) among young adults is increasing in the United States [(1)][1]. Infective endocarditis (IE) is of specific concern in this population, and accounts for 5% to 10% of deaths [(2,3)][2]; however, its economic impact is unreported [(4)][3]. Accordingly, we sought to

The Beta-adrenergic receptors (β-ARs) stimulation enhances contractility through protein kinase-A (PKA) substrate phosphorylation. This PKA signaling is conferred in part by PKA binding to A-kinase anchoring proteins (AKAPs). AKAPs coordinate multi-protein signaling networks that are targeted to specific intracellular locations, resulting in the localization of enzyme activity and transmitting intracellular actions of neurotransmitters and hormones to its target substrates. In particular, mAKAP (muscle-selective AKAP) has been shown to be present on the nuclear envelope of cardiomyocytes with various proteins including: PKA-regulatory subunit (RIIα), phosphodiesterase-4D3, protein phosphatase-2A, and ryanodine receptor (RyR2). Therefore, through the coordination of spatial-temporal signaling of proteins and enzymes, mAKAP controls cyclic-adenosine monophosphate (cAMP) levels very tightly and functions as a regulator of PKA-mediated substrate phosphorylation leading to changes in calcium availability and myofilament calcium sensitivity. The goal of this review is to elucidate the critical compartmentalization role of mAKAP in mediating PKA signaling and regulating cardiomyocyte hypertrophy by acting as a scaffolding protein. Based on our literature search and studying the structure–function relationship between AKAP scaffolding protein and its binding partners, we propose possible explanations for the mechanism by which mAKAP promotes cardiac hypertrophy.

Background Minimally invasive aortic valve replacement (mAVR) is increasingly preferred over conventional AVR (cAVR). However, data comparing these procedures present conflicting results. Hence, we conducted a systematic review and meta-analysis comparing clinical results in these cohorts. Method Only randomized controlled trials (RCT) and propensity-matched observational studies (POS) (1998–2013) comparing clinical outcome of patients subjected to mAVR or cAVR were pooled. Continuous data was compared using mean/standardized mean difference (MD/SMD) while categorical results were pooled to obtain an odds ratio (OR) with a 95% confidence interval. Results A total of 18 studies (6 RCT and 12 POS) (1973 mAVR patients; 2697 cAVR patients) were analyzed. The mean ischemic time was significantly longer with mAVR (MD 9.42 minutes [4.25–14.59]; p

Data comparing long-term results after percutaneous intervention with drug-eluting stents (DES/PCI) and coronary artery grafting (CABG) in diabetic patients (pts) with multi-vessel disease is conflicting. We have conducted a systematic review and meta-analysis to help answer this issue.MEDLINE, WoS, and Scopus were systematically analysed to yield observational studies (OBS) or randomised controlled trials (RCT) fulfilling search criteria. Odds ratio (OR) for studied end-points were obtained with inverse variance random effects analysis. Results are presented with 95% confidence intervals with significance at p0.05.A total of 14 studies (5 RCT; 9 OBS) including more than 5000 pts were selected for review. Early/30-day was lower in the DES/PCI cohort [OR 0.49(0.27, 0.88); p=0.02; I(2)=0%]. Post-procedural stroke was higher in the CABG (1.8%) cohort compared to DES/PCI (0.17%; p0.01). A pooled analysis of RCT demonstrated that stroke rate was similar in both cohorts at the end of one year [OR 0.84(0.19, 3.74); p=0.82; I(2) =67%]. During a follow-up of three to five years, repeat intervention was much higher in the DES/PCI cohort [OR 3.02(2.13, 4.28; p0.01]. The odds of suffering an adverse cardiovascular /cerebrovascular event were 1.71 (1.27, 2.3) times higher in the DES/PCI cohort compared to CABG.In diabetic patients with multivessel disease, early mortality is lower in the DES/PCI cohort. While peri-procedural stroke rates are lower with PCI, they are, however, comparable at the end of one year. Use of drug-eluting stents leads to a higher rate of re-intervention and major cardiovascular/cerebrovascular events at three to five years.

This study evaluated preoperative balloon aortic valvuloplasty (BAV) as a technique to decrease aortic valve replacement (AVR) risk in patients who have severe symptomatic aortic valve stenosis with substantial comorbidity. We report the outcomes of 18 high-risk patients who received BAV within 180 days before AVR from November 1993 through December 2011. Their median age was 78 years (range, 51–93 yr), and there were 11 men (61%). The pre-BAV median calculated Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) was 18.3% (range, 9.4%–50.7%). Preoperative left ventricular ejection fraction measured a median of 0.23 (range, 0.05–0.68), and the median aortic valve area index was 0.4 cm2/m2 (range, 0.2–0.7 cm2/m2). The median interval from BAV to AVR was 28 days (range, 1–155 d). There were no strokes or deaths after BAV; however, 4 patients (22%) required mechanical circulatory support, 3 (17%) required femoral artery operation, and 1 (6%) developed severe aortic valve regurgitation. After BAV, the median STS PROM fell to 9.1% (range, 2.6%–25.7%) (compared with pre-BAV, P Staged BAV substantially reduces the operative risk associated with AVR in selected patients.

Data regarding the long-term clinical effects of a continuous flow left ventricular assist device (CF-LVAD) on hepato-renal function is limited. Hence our aim was to assess changes in hepato-renal function over a one-year period in patients supported on a CF-LVAD.During the study period 126 patients underwent CF-LVAD implant. Changes in hepato-renal laboratory parameters were studied in 61/126 patients successfully supported on a CF-LVAD for period of one year. A separate cohort of a high-risk group (HCrB) of patients (56/126) with a serum creat1.9 mg/dL (168 μmol/L) (75th percentile) or a serum bil1.5 mg/dL (25.65 μmol/L) (75th percentile) was created. Changes in serum creatinine and bilirubin were analysed at regular intervals for this group along with the need for renal replacement therapy.Baseline creatinine and blood urea nitrogen (BUN) for the entire cohort was 1.4[1.2,1.9 mg/dL] [123.7(106,168) μmol/L) and 27[20,39.5 mg/dL] [9.6(7.1,14.1) mmol/L] respectively. After an initial reduction at the end of one month [1(0.8,1.2) mg/dL; 88(70,105) μmol/L] (p0.0001), a gradual increase was noted over the study period to reach (1.25[1.1,1.5] mg/dL; 106(97.2,132.6) μmol/L] (p=0.0003). The serum bilirubin normalised from a [1(0.7,1.55) mg/dL] [17(18.8,25.7) μmol/L) to 0.9(0.6,1.2)mg/dL [15.4(10.2,20.5) μmol/L] (p=0.0005) and continued to decline over one year. Improvement in the synthetic function of the liver was demonstrated by a rise in the serum albumin levels to reach 4.3[4.1,4.5] [43(41,45) gm/L] at the end of one year (p0.0001). The baseline serum creatinine and bilirubin for the high-risk cohort (HCrB) was 1.9(1.3,2.4) mg/dL [168(115,212) μmol/L] and 1.7(1.00,2.4) mg/dL [29(17.1,68.4) μmol/L] respectively. The high-risk cohort (HCrB) demonstrated a trend towards higher 30-day mortality (p=0.06). While the need for temporary renal replacement therapy was higher in this cohort (16% vs. 4%; p=0.03), only 3% need it permanently. A significant reduction in creatinine was apparent at the end of one month [1.1(0.8,1.4) mg/dL; 97(70.7,123.7) μmol/L] (p0.0001) and then remained stable at [1.3(1.1,1.5) mg/dL; 115(97,132.6) μmol/L]. Bilirubin demonstrated a 30% decline over one month and then remained low at [0.7(0.5,0.8) mg/dL; 62(44,70) μmol/L] p=0.0005 compared to the pre-operative baseline.Hepato-renal function demonstrates early improvement and then remains stable in the majority of patients on continuous flow left ventricular assist device support for one year. High-risk patients demonstrate a higher 30-day mortality and temporary need for renal replacement therapy. Yet even in this cohort, improvement is present over a period of one year on the device, with a minimal need for permanent haemodialysis.

Background: Anti-platelet therapy is an important component of medical therapy post coronary artery bypass grafting (CABG). While aspirin administration is a Class I indication after CABG, the benefit of concomitant clopidogrel is a controversial issue. Methods: We searched OVID Medline, Cochrane, Scopus, and EMBASE for randomized control trials and observational studies comparing aspirin W placebo to aspirin R clopidogrel after CABG. Results: Eleven articles (five randomized control trials and six observational studies) including 25,728 patients met inclusion criteria. Early saphenous vein graft occlusion was reduced with the use of dual anti-platelet therapy (risk ratio (RR) = 0.59, 95% CI 0.43-0.82, p = 0.02). In- hospital or 30-day mortality was lower with aspirin R clopidogrel (0.8%) compared to aspirin alone (1.9%) (p < 0.0001), while risk of angina or perioperative myocardial infarction was comparable (RR = 0.60, 95% CI 0.31-1.14, p = 0.12). Patients treated with aspirin R clopidogrel demonstrated a trend towards a higher incidence of major bleeding episodes as compared to patients treated with aspirin alone (RR = 1.17, 95% CI 1.00-1.37, p = 0.05). In a pooled analysis of studies involving off-pump CABG compared to aspirin alone, dual anti-platelet therapy reduced the risk of perioperative myocardial infarction and saphenous graft occlusion by 68% (47% to 71%) and 55% (2% to 79%) respectively. Conclusion: Dual anti-platelet therapy after CABG improved early saphenous vein graft patency, but may increase the risk of bleeding. The use of dual anti- platelet therapy appears to be most beneficial in patients undergoing off-pump CABG. Prospective randomized studies are necessaryto determine whetherthis beneficial effect of dualtherapy is alsoachieved in patients undergoing on pump CABG. doi: 10.1111/jocs.12074 (J Card Surg 2013;28:109-116)

Background Coronary artery bypass graft surgery is superior to percutaneous intervention in diabetic patients with multivessel disease. The use of bilateral internal thoracic arteries (BITA) may provide better long-term graft patency, but the risk of postoperative deep sternal wound infection has limited its use in diabetic patients. However, studies have reported conflicting results, and require systematic evaluation. Methods MEDLINE, EMBASE, World of Science, and the Cochrane library were searched for randomized controlled trials and observational studies comparing the incidence of deep sternal wound infection in diabetic patients undergoing either left internal thoracic artery (LITA) or BITA harvest. We used random effect models to compare risk ratios within groups. Results One randomized controlled trial and 10 observational studies (126,235 diabetic patients: 122,465 LITA, 3,770 BITA) met inclusion criteria. Deep sternal wound infection occurred in 3.1% and 1.6% for the BITA and LITA cohorts, respectively. The risk ratio for deep sternal wound infection development was 1.71 (1.37 to 2.14) for BITA compared with LITA. Patients who underwent skeletonized BITA harvest had a similar risk of deep sternal wound infection compared with LITA (0.9 [0.42 to 2.09]), although pedicled harvest demonstrated increased risk (1.77 [1.4 to 2.23]). Early mortality was comparable in the LITA cohort (2.5%) and the BITA cohort (2.3%; p = 0.8). Conclusions The risk of deep sternal wound infection can be minimized in diabetic patients undergoing coronary artery bypass graft surgery by performing ITA harvested in a skeletonized manner with meticulous attention to preserving sternal blood flow. Pedicled harvest is to be discouraged when utilizing both ITA owing to a significant increase in the risk of postoperative deep sternal wound infection.

Obstructive hypertrophic cardiomyopathy (HCM) is an important cause of heart failure in children, but there are limited data addressing outcome of myectomy in children. Our objective was to evaluate the early and late results of septal myectomy in pediatric HCM.We reviewed 127 consecutive patients (62% male) who underwent transaortic septal myectomy for obstructive HCM from January 1975 to December 2010 at 21 or less years of age. Mean age at operation was 12.9 ± 5.5 years. Preoperatively, mean maximum instantaneous gradient was 89 mm Hg and 95% had significant systolic anterior motion (SAM) with mitral regurgitation (MR). Implantable cardioverter defibrillator (ICD) and permanent pacemaker prior to surgery was present in 21 patients (17%) and 15 (11.7%), respectively.Transaortic extended left ventricular septal myectomy was performed in all patients with no early deaths. Iatrogenic morbidity included new aortic valve regurgitation requiring repair in 7 (5.5%), mitral regurgitation needing repair in 2 (1.5%), ventricular septal defect in 1 (1%), and heart block requiring permanent pacemaker in 1 (1%). An ICD was implanted postoperatively in 8 during the same hospital admission. Mean MIG decreased from 89 to 6 mm Hg (p0.0001). Postoperatively, residual chordal SAM was present in 23% with mild or no MR; moderate MR was detected in 1 patient. Four patients (3%) died late during the mean follow-up period of 8.3 years (maximum, 37 years); 1 death was sudden. Overall survival was 98.6%, 94.9%, 92.4%, and 92.4% at 5, 10, 15, and 20 years, respectively. Freedom from any cardiac reoperation was 91.2%, 87.8%, 78.7%, and 72.7% at 5, 10, 15, and 20 years, respectively. Repeat septal myectomy was performed in 6 patients (5%). At late follow-up, 95% were in New York Heart Association functional class I or II and 25 patients underwent late ICD placement.Septal myectomy is safe and effective in children with obstructive HCM, but limited exposure may increase risk of aortic or mitral valve injury. Late survival is better than the previously published untreated natural history of HCM. Patient selection and surgical expertise remain critical components of septal myectomy, especially before considering a prophylactic myectomy in a seemingly asymptomatic patient.

Axial flow left ventricular assist device (LVAD) implantation is an effective therapy for patients with advanced heart failure. As the preoperative hepatic and renal function play a critical role in determining adverse events after LVAD implantation, we analyzed the predictive role of the model for end-stage liver disease (MELD) score in determining in-hospital mortality after surgery. One hundred twenty-six patients underwent implant of an LVAD at our institution. Their individual preoperative MELD scores and perioperative total blood product usage (TBPU) were calculated. As LVAD implant as a reoperation is known to influence postoperative bleeding and mortality independently, the patients were divided into group I (first cardiac surgery) and group II (reoperative surgery). Group I: LVAD implantation was performed in 68/126 (54%) patients as their first cardiac surgery. The mean MELD score was 16.3 ± 6. Median TBPU for this group was 20.7 (0, 135) units. Inhospital mortality/30-day mortality was 4/68 (5.8%). Increasing MELD score (c-statistic = 0.88) and TBPU were found to be predictors of early mortality. An increasing MELD score was associated with more TBPU (p < 0.01) with a 10.9 ± 3 TBPU increase per a 10 unit rise in the MELD score. Group II: Of the 126 patients, 58 (46%) underwent LVAD implantation as a reoperation. Mean MELD score for these patients was 16 ± 5. Inhospital mortality/30-day mortality in this group was 12% and median TBPU was 30 (4,153) units. The MELD score was not predictive of inhospital mortality in these patients (p = 0.97). The MELD score is predictive of early mortality in patients undergoing LVAD implantation as their first cardiac surgery. Use of this score to select patients for LVAD implantation may be appropriate.

Pseudoaneurysm of the aortic arch is a rare entity, usually seen after cardiac operations or chest trauma. Here we report a 32-year-old man who presented 10 years after blunt chest trauma with a giant aortic arch pseudoaneurysm. He finally underwent surgical intervention in which the pseudoaneurysm was closed from inside with use of an inlay patch method.

Moderate ischemic mitral regurgitation (MR) is often present in patients undergoing coronary artery bypass grafting (CABG). However, the clinical benefit of repairing moderate MR during CABG is unproven. We searched multiple databases to identify original studies comparing isolated CABG versus combined CABG and MR surgery (mitral valve surgery with coronary artery bypass grafting [MVCABG]); survival (either early or midterm) was the primary end point. Risk ratio (RR) or standardize mean difference was selected as the effect estimates; survival was compared by pooling hazard ratios. All results are presented with 95% CIs; p0.05 is statistically significant. Eleven studies (7 retrospective and 4 randomized controlled trials; 547 MVCABG and 900 CABG patients) were included in our meta-analysis. Concomitant mitral valve repair significantly prolonged surgical duration (p0.01). Early mortality (MVCABG 6.9% and CABG 6%) was comparable (RR 1.3 [0.9 to 1.8]; p = 0.11). At follow-up, the MVCABG patients had similar New York Heart Association class (standardize mean difference -0.73 (-1.64 to 0.18; p = 0.11). However, patients who underwent concomitant mitral valve surgery had less MR at follow-up (recurrent significant MR, RR 0.37 [0.22 to 0.62]; p = 0.001; mean MR grade, mean difference = 0.39 [0.26 to 0.59]; p0.001). Midterm survival rate (mean follow-up 5 years) was comparable in both groups (hazard ratio for mortality in the MVCABG cohort 1.1 [0.9 to 1.3]; p = 0.38). In conclusion, concomitant repair of moderate ischemic MR leads to improved mitral valve competence at follow-up; however, this was not translated into any functional or survival benefit for adding valve repair to CABG for these patients at 5 years of follow-up.

Objectives: Hawthorn extract consumption is becoming more widespread among the Jordanian population with cardiovascular disorders. We conducted this prospective observational longitudinal study to determine the impact of hawthorn extract on bleeding risk in patients who undergo cardiac surgery. Methods: A prospective observational study was performed on 116 patients who underwent cardiac surgery in the period between June 2014 and May 2015. Patients were divided into two groups: Group I (patients recently consumed hawthorn extract) and Group II (patients never consumed hawthorn extract). Endpoint measures included the rates of reopening to control bleeding, early mortality, duration of intensive care unit stay, total in-hospital stay period, and duration and amount of chest tube drainage. Results: Hawthorn patients had a significantly higher rate of postoperative bleeding necessitating take back to the operating room compared to the control group (10% versus 1%; P = .03) respectively. The overall mortality rate for group I and II was 4% and 0% respectively; P = .17. Chest tubes were kept in for longer times in group I compared to group II (54 ± 14.6 versus 49 ± 14.7 hours respectively; P = .01). Group I stayed longer in the intensive care unit compared to group II (24 versus 22 hours respectively; P = .01). The total in-hospital stay period was comparable between the two groups. Conclusion: Hawthorn extract consumption does increase the potential for bleeding and the amount of chest tube output after cardiac surgery.

Background: Renal dysfunction is a common complication after cardiovascular surgery. Controversial issues have been discussed regarding the role of N-acetyl cysteine in the prevention of postoperative renal dysfunction. The purpose of this meta-analysis is to assess whether N-acetyl cysteine offers any protection against the development of acute renal dysfunction after cardiac surgery. Methods: Multiple databases were searched for randomized trials comparing the role of N-acetyl cysteine and placebo in human patients undergoing cardiac surgery. End-points studied were: the incidence of acute renal failure, hemodialysis, early mortality, duration of hospital stay, and maximal change in creatinine values. Dichotomous variables were compared using the risk difference (RD) calculated with inverse weighting; continuous data was pooled as (standardized) mean difference. Results are presented with 95% confidence interval (P < .05 is significant); results are presented within 95% confidence interval.Results: Thirteen randomized trials (713 and 707 patients in the N-acetyl cysteine and control groups, respectively) were included in the present analysis; nine dealing with patients at high-risk for acute renal failure. The incidence of postoperative acute renal dysfunction was 23% and 36% in the N-acetyl cysteine and control cohorts, respectively. N-acetyl cysteine therapy did not reduce acute renal dysfunction in the high-risk cohort [RD -0.03 (-0.09 to 0.02); P = .22; I2 = 24%]. Maximal change in creatinine levels after surgery was also comparable [standardized mean difference 0.07 (-0.23, 0.09); P = .39]. Early mortality was 2.9% and 3.7% in the N-acetyl cysteine and control cohorts respectively; [RD 0 (-0.03 to 0.02); P = .63; I2 = 20%]. Hospital stay (mean length of stay 10.4 and 10.1 days in the N-acetyl cysteine and control cohorts, respectively) was also similar in both cohorts [WMD 0.17 (-0.02 to 0.37) days; P = .81]. Conclusion: Prophylactic N-acetyl cysteine therapy does not reduce the incidence of renal dysfunction in high-risk patients undergoing cardiac surgery.
