Until recently, the diagnosis is often not established until the tumor is advanced with vital cardiac structure involved or distal metastasis, mainly because the symptoms are initially nonspecific. The natural history of cardiac angiosarcoma is characterized by a short clinical course and a fatal outcome. Surgical resection remains the preferential therapy for palliation or cure, where as irradiation and chemotherapy have only limited use. We herein reported a successful radical resection of cardiac angiosarcoma with concomitant reconstruction of right coronary artery, tricuspid leaflet, and atrial wall.

Twenty years ago the patient underwent radical cystectomy and bilateral ureterosigmoidostomy because of bladder cancer After that, his micturition was via the rectum. We did not experience that before. As is known, monitoring of urine output is very important after cardiac surgery The patient was consulted with an urologist for how to monitor urine output in him. Transrectal catheterization was recommended for our follow-up, but before the catheterization bowel cleansing is necessary. Four-vessel on-pump coronary artery bypass graft surgery was performed without any problem. Peroperative urine volume and arterial blood gas results were normal. Urine output is a sensitive variable reflecting the patient's effective blood volume and tissue perfusion. Urinary catheterization is a standard for all cardiac surgeries and it allows the patients' urine to drain freely from the bladder for collection. Monitoring of urine output in patients with ureterosigmoidostomy is impossible by standard urinary catheterization method. In this casewe performed transrectal catheterization for Urine flow follow-up. Urine flow follow-up is essential after the open-heart surgery and it can be measured in different ways, as in our case.展开更多

But it is not always feasible. Current cardioplegic techniques do not consistently avoid myocardial ischemic damage. So we use on pump beating heart technique to supplement off-pump CABG. Methods Based on 860 off-pump CABG cases between Aug 1998 to Aug 2000. From Aug 1999 to Aug 2000, 46 CABG cases were performed with on pump beating heart technique at Mani-pal Hospital Heart Foundation, Bangalore, India. All surgeries were performed through a median sternotomy. Exposure techniques were tailored to individual vessels and cardiac regions and local immobilization was performed with octopus. Vascular control was achieved with occluders and shunts. Total cardiopulmonary bypass (CPB) was established before or during CABG and normolthemia was used. Results Among 46 on -pump beating heart CABG patients, 26 patients used CPB before or during OP - CABG because of unstable hemodynamics and electric instability , 7 had very deep intramyocardial left anterior descending arteries, 5 patients had poor LV function (LVEF < 30 % ), 8 patients had cardiomegaly. The average number of grafts was 3.5. No operative mortality. Three patients had postoperative myocardial infarction. Anesthetic time 4. 5±1. 2 hours, extubation time 10±2. 5 hours, blood lost 680±230 mL, blood requirement 540±150 mL, preoperative LVEF 50. 3±13 % , postoperative LVEF 64. 1±14 %, ICU stay 1. 5±0. 5 days, hospi- tal stay 9.2±1.8 days. Conclusion Complete coronary revascularization with on pump beating heart is a supplement for off - pump CABG when it is not feasible. It eliminates intraoperative globe myocardial ischemia and avoids transient myocardial injury during cardioplegic arrest and myocardial reperfusion.展开更多

Method: A cross sectional, descriptive study comprised 1093 consecutive patients (≤45 years), with a diagnosis of CAD, who underwent percutaneous intervention (PCI) or coronary bypass graft (CABG) from 2010 to 2012. Data on demographic features, cardiovascular risk factors, and angiographic findings were studied. Result: There were 1093 young patients (234 females, 859 males) with proven CAD;the mean age of 39 ± 3 years and the mean BMI were 28 ± 4.7 kg/m2. According to the treatment plan, patients were classified into two groups: PCI and CABG groups (n = 898,195 respectively). Obesity was the most prevalent risk factor (73.6%). In the risk factor assessment, it was noticed: 27% with diabetes mellitus, 37% with hypertension, 38% with family history, 39% with hyperlipidimia, and 54% smokers. Angiographic study revealed that 10 (1%) had left main coronary disease, 747 (68%) patients had single vessel disease, 181 (17%) had two-vessel disease and that 155 (14%) had three-vessel disease. The most common anatomical involvement was the anterior wall territory. Conclusion: Young CAD patients from Iran have different risk profile. Although atherosclerosis of the coronary arteries is less prominent in young patients, more often it is accompanied by decreased left ventricular function. There is a need for prevention plan to control obesity by targeting young adults in the population.展开更多

We report a 42-year-old patient with ALCAPA managed with intrapulmonary interruption of the left main coronary artery (LMCA) ostea and grafting of the LMCA with left internal mammary artery so as to restore antegrade coronary flow. This restores a dual-coronary-artery system and also allows antegrade blood flow as in a normal coronary artery to a large area of viable myocardium. This strategy is simple to accomplish and is more physiological in an anteriorly placed and dilated LMCA as seen in our case.展开更多

Methods: We report a single surgeon, single center experience of the first 37 consecutive patients undergoing off-pump surgery. Patients were selected for OPCAB (study group) individually and matched retrospectively to a control group of 113 patients performed over an identical time frame. Data were retrieved from a hospital data base (TOMCAT). Results: Mean Logistic European System of Cardiac Operative Risk Stratification (EuroSCORE) was slightly higher in the off-pump group (3.8% versus 2.9%). One patient died during the study and this was in the off-pump CAB group (OPCAB-30 day mortality 2.7%). Operating time was slightly shorter in the off-pump group (3 hours 28 minutes versus 3 hours 49 minutes, p = 0.15). After exclusion of outliers, total hospital stay was significantly shorter for off-pump cases (mean 6.8 days versus 8.37 days), while Intensive Care Unit (ICU) stay (1.2 versus 1.4 days) and ventilation time were only slightly shorter (9.35 hours versus 10.6 hours) for off-pump cases. Chest tube drainage was significantly lower in the off-pump group (484 ml versus 744 ml, p = 0.04) with correspondingly slightly lower transfusion requirements and significantly increased discharge haemoglobin concentrations in OPCAB. There was one cerebrovascular accident (CVA) in the off-pump group and none in the on-pump group. Conclusion: In this study we show short term outcomes for introduction of off-pump into surgical technique. Length of ICU stay, ventilation times, chest tube drainage, transfusion re0 quirements and pre-discharge haemoglobin concentration all appeared superior in the off pump group. The off-pump technique was safely introduced into the surgeon`s service with relatively little mortality. Experience of surgeon was considered advantageous for fast adaption of the technique. However, numbers were too small to make strong inferences. With practice more patients should benefit from the technique.展开更多

The hemodynamic parameters were monitored.Results: In the CHD patients, 64.9% were differentiated as Qi-Yin deficiency, 67.6% were complicated with phlegm syndrome and 62.2% with blood stasis, suggesting that Qi-deficiency, phlegm and stasis are the basic pathogenetic factors in patients with CABG. Moreover, the peri-operative syndrome was correlated with the condition of coronary artery lesion, heart and lung functions before operation, and the extracorporeal circulation time during the operation.Conclusion: TCM SD conducting in peri-operative stage might be useful in exploring the patterns of syndrome alteration which provided a basis for preventing peri-operative complications and elevating success rate of operation.展开更多

文摘BACKGROUND Lack of mobilization and prolonged stay in the intensive care unit(ICU)are major factors resulting in the development of ICU-acquired muscle weakness(ICUAW).ICUAW is a type of skeletal muscle dysfunction and a common complication of patients after cardiac surgery,and may be a risk factor for prolonged duration of mechanical ventilation,associated with a higher risk of readmission and higher mortality.Early mobilization in the ICU after cardiac surgery has been found to be low with a significant trend to increase over ICU stay and is also associated with a reduced duration of mechanical ventilation and ICU length of stay.Neuromuscular electrical stimulation(NMES)is an alternative modality of exercise in patients with muscle weakness.A major advantage of NMES is that it can be applied even in sedated patients in the ICU,a fact that might enhance early mobilization in these patients.AIM To evaluate safety,feasibility and effectiveness of NMES on functional capacity and muscle strength in patients before and after cardiac surgery.METHODS We performed a search on Pubmed,Physiotherapy Evidence Database(PEDro),Embase and CINAHL databases,selecting papers published between December 2012 and April 2023 and identified published randomized controlled trials(RCTs)that included implementation of NMES in patients before after cardiac surgery.RCTs were assessed for methodological rigor and risk of bias via the PEDro.The primary outcomes were safety and functional capacity and the secondary outcomes were muscle strength and function.RESULTS Ten studies were included in our systematic review,resulting in 703 participants.Almost half of them performed NMES and the other half were included in the control group,treated with usual care.Nine studies investigated patients after cardiac surgery and 1 study before cardiac surgery.Functional capacity was assessed in 8 studies via 6MWT or other indices,and improved only in 1 study before and in 1 after cardiac surgery.Nine studies explored the effects of NMES on muscle strength and function and,most of them,found increase of muscle strength and improvement in muscle function after NMES.NMES was safe in all studies without any significant complication.CONCLUSION NMES is safe,feasible and has beneficial effects on muscle strength and function in patients after cardiac surgery,but has no significant effect on functional capacity.
