Transcatheter closure of iatrogenic perimembranous ventricular septal defect after aortic valve and ascending aorta replacement using an Amplatzer membranous ventricular septal occluder

Iatrogenic perimembranous ventricular septal defect is a rare complication after surgical replacement of the aortic valve, and so transcatheter closure of such a defect is not a routine procedure. We report the successful closure of an iatrogenic perimembranous ventricular septal defect which occurred after the replacement of the aortic valve and ascending aorta. (Cardiol J 2008; 15: 189-191

The evaluation of simultaneous combined surgery of the heart and thyroid - own experience

Background: Patients referred for cardiac surgery usually also have other comorbidities. These include thyroid disease, which is relatively common in patients with heart problems. Objective: The aim of the study was to evaluate the feasibility of combined cardiac surgery and thyroidectomy. Material and methods: Six patients (age range: 54-74 years) qualified for elective, simultaneous surgeries on the heart and the thyroid were included in the study. In preparation for thyroidectomy, three patients were diagnosed with diseases requiring cardiac surgery. Two patients, initially referred for coronary artery bypass surgery in one case, and surgery for recurrent fluid in the pericardial sac with concomitant mitral and tricuspid valve regurgitation and atrial fibrillation in the other, were diagnosed in large hyperactive goitre. The last patient with a history of oncology (lung tumour), admitted to the Department of Cardiology due to a heart attack, had a CT scan of the chest, which revealed retrosternal goitre narrowing the lumen of the trachea to 9 mm. All patients underwent combined heart and thyroid operation and were discharged home 8-27 days after surgery. Conclusions: Although preoperative qualification requires a very cautious and individual approach, simultaneous surgeries in patients requiring thyroid and heart interventions are expedient and should be promoted

Fibroelastoma papillare zastawki aortalnej u 67−letniej pacjentki po przebytym zawale serca

We present a case of a 67-year-old female patient with diagnosed papillary fibroelastoma (PFE) of the aortic valve. Eight months before the tumour discovery a non-ST segment elevation myocardial infarction without essential coronary artery restriction was diagnosed. The tumour was excised (during the aortotomy under cardiopulmonary bypass at systemic hypothermia) without any aortic valve injury. The main symptoms of PFE along with diagnostic techniques and treatment were described.We present a case of a 67-year-old female patient with diagnosed papillary fibroelastoma (PFE) of the aortic valve.

safety and efficacy of miniaturized extracorporeal circulation when compared with off pump and conventional coronary artery bypass grafting evidence synthesis from a comprehensive bayesian framework network meta analysis of 134 randomized controlled trials involving 22 778 patients

Coronary artery bypass grafting (CABG) remains the standard of care in patients with extensive coronary artery disease. Yet the use of cardiopulmonary bypass (CPB) is believed to be a major determinant of perioperative morbidity. Novel techniques are sought to tackle the shortcomings of CPB, among them off-pump coronary artery bypass (OPCAB) and miniaturized extracorporeal circulation (MECC) systems have been extensively tested in randomized controlled trials (RCTs). To assess perioperative safety and efficacy of MECC and OPCAB when compared with conventional extracorporeal circulation (CECC).Published literature and major congress proceedings were screened for RCTs evaluating the safety and efficacy of MECC, OPCAB and CECC. Selected end-points such as 30-day all-cause mortality, myocardial infarction (MI), cerebral stroke, postoperative atrial fibrillation (POAF) and renal dysfunction were assessed in a Bayesian-framework network meta-analysis.A total of 134 studies with 22 778 patients were included. When compared with CECC, both OPCAB and MECC significantly reduced 30-day all-cause mortality [odds ratios (95% credible intervals): 0.75 (0.51-0.99) and 0.46 (0.22-0.91)], respectively. No differences in respect to MI were demonstrated with either strategy. OPCAB, when compared with CECC, reduced the odds of cerebral stroke [0.57 (0.34-0.80)]; 60% reduction was observed with MECC when compared with CECC [0.40 (0.19-0.78)]. Both OPCAB and MECC reduced the odds of POAF [0.66 (0.48-0.90) and 0.62 (0.35-0.98), respectively] when compared with CECC. OPCAB conferred over 30% reduction of renal dysfunction when compared with CECC [0.69 (0.46-0.92)]. MECC reduced these odds by more than 50% [0.47 (0.24-0.89)]. Ranking of treatments emerging from the probability analysis (highest to lowest SUCRA values) was MECC followed by OPCAB and CECC.MECC and OPCAB both improve perioperative outcomes following coronary bypass surgery when compared with conventional CABG performed with extracorporeal circulation. MECC may represent an attractive compromise between OPCAB and CECC

Systematic review and meta-analysis of randomized controlled trials assessing safety and efficacy of posterior pericardial drainage in patients undergoing heart surgery.

OBJECTIVES To investigate the potential beneficial effects of posterior pericardial drainage in patients undergoing heart surgery. METHODS Multiple online databases and relevant congress proceedings were screened for randomized controlled trials assessing the efficacy and safety of posterior pericardial drainage, defined as posterior pericardiotomy incision, chest tube to posterior pericardium, or both. Primary endpoint was in-hospital/30 days' cardiac tamponade. Secondary endpoints comprised death or cardiac arrest, early and late pericardial effusion, postoperative atrial fibrillation (POAF), acute kidney injury, pulmonary complications, and length of hospital stay. RESULTS Nineteen randomized controlled trials that enrolled 3425 patients were included. Posterior pericardial drainage was associated with a significant 90% reduction of the odds of cardiac tamponade compared with the control group: odds ratio (95% confidence interval) 0.13 (0.07-0.25); P < .001. The corresponding event rates were 0.42% versus 4.95%. The odds of early and late pericardial effusion were reduced significantly in the intervention arm: 0.20 (0.11-0.36); P < .001 and 0.05 (0.02-0.10); P < .001, respectively. Posterior pericardial drainage significantly reduced the odds of POAF by 58% (P < .001) and was associated with significantly shortened (by nearly 1 day) overall length of hospital stay (P < .001). Reductions in postoperative complications translated into significantly reduced odds of death or cardiac arrest (P = .03) and numerically lower odds of acute kidney injury (P = .08). CONCLUSIONS Posterior pericardial drainage is safe and simple technique that significantly reduces not only the prevalence of early pericardial effusion and POAF but also late pericardial effusion and cardiac tamponade. These benefits, in turn, translate into improved survival after heart surgery

Clinical Safety and Effectiveness of Endoaortic as Compared to Transthoracic Clamp for Small Thoracotomy Mitral Valve Surgery: Meta-Analysis of Observational Studies.

Controversies remain on the increased rate of neurological events after small thoracotomy mitral valve surgery attributed to endoaortic balloon occlusion (EABO). Systematic literature search of databases identified 17 studies enrolling 6,643 patients comparing safety and effectiveness of EABO versus transthoracic clamp. In a meta-analysis, there was no difference in occurrence of cerebrovascular events, all-cause mortality, and kidney injury. EABO was associated with a significantly higher risk of iatrogenic aortic dissection (0.93% versus 0.13%; risk ratio, 4.67; 95% confidence interval, 1.62 to 13.49; p = 0.004) and a trend toward longer operative times. The data is limited to observational studies
