Del Nido cardioplegia is believed to be both clinically and economically efficient. The interest in this myocardial protection method has been continuously growing. However, the evidence is not clear. The article summarizes recent reports regarding del Nido cardioplegia.
Background Minimally invasive procedures are demanding in terms of cardioprotection. In many leading centres Bretschneider HTK solution is used for mitral valve surgery. The study was designed to provide comparison of the del Nido and Bretschneider HTK protocol. Methods Patients who underwent minimally invasive mitral valve repair for primary mitral regurgitation and received single delivery of either del Nido (Group 1) or Bretschneider HTK cardioplegia (Group 2) were matched on basis of age, gender and length of the cross-clamp time. The groups were compared in terms of major adverse cardiac and cerebrovascular events (death, myocardial infarction, stroke), high sensitivity troponin T (hs-TnT) and creatine kinase- MB isoenzyme (CK-MB) release at 12 h and 24 h following the surgery, incidence of low cardiac output syndrome (LCOS), postoperative arrhythmia, transfusions and postoperative renal function. Results Case control matching selected 38 pairs of patients. None of patients died, nor suffered from myocardial infarction or stroke. Troponin values did not differ at 12 h (median: 281.0 pg/mL vs 313.0 pg/mL; p = .38) and 24 h (median: 261.0 pg/mL vs 299.0 pg/mL; p = .54), as well as CK-MB at 12 h (median: 25.0 ng/mL vs 29.0 ng/mL; p = .31) and 24 h (median: 11.0 ng/mL versus 9.6 ng/mL; p = .46). Difference in occurrence of LCOS was insignificant (2 vs 7; 5.2% vs 18.4%; p =.15). No difference was shown in incidence of postoperative arrhythmia, transfusions and renal function. Conclusions Del Nido cardioplegia can be used safely as an alternative for Bretschneider HTK for minimally invasive mitral valve surgery.
Background:To perform a retrospective analysis of patients who underwent endoscopic atraumatic coronary artery off-pump bypass grafting (EACAB) in a single center over a period of 11 years.Methods: Data was acquired from the hospital registry and patient medical records. In order to determine changes in clinical profile, patients were subdivided into three groups regarding year of surgery:
Introduction Despite their high effectiveness, surgical aortic valve replacement (AVR) and transcatheter aortic valve implantation (TAVI) are associated with substantial risk of bleeding. Although procedure-related hemostasis disorders might be crucial for safety of both procedures, the amount of data on the peri-procedural status of hemostasis in patients with aortic valve stenosis (AS) subjected to AVR and TAVI is negligible. Aim To investigate the profile of peri-procedural hemostasis in elderly patients with AS, subjected to aortic valve prosthesis implantation. Material and methods We performed a prospective analysis of global hemostasis using ROTEM thromboelastometry and platelet reactivity assessment using impedance aggregometry in 30 consecutive patients ≥ 70 years old subjected to AVR and TAVI. All tests were performed within 24 h before, directly and 24 h after the procedures. Results Surgical aortic valve replacement was characterized by transient hypofibrinogenemia and von Willebrand factor (vWF) depletion, which quickly recovered within 24 h after AVR. Transcatheter aortic valve implantation was characterized by substantial alteration of platelet function and vWF depletion with significant platelet reactivity impairment and increase in platelet sensitivity to antiplatelet agent, early after the procedure. TAVI-related hemostasis alterations were not recovered at 24 h after the procedure. Conclusions Surgical and transcatheter aortic valve replacement procedures are associated with substantial and diverse peri-procedural hemostasis disorders. Since hemostasis disorders related to TAVI are mainly characterized by impaired platelet function, early dual antiplatelet prophylaxis after TAVI requires careful consideration.
Introduction Minimally invasive mitral repair is less traumatic and more acceptable for the patient than traditional surgery. However, it is a challenging procedure that requires effort from all the personnel involved. Aim To investigate the results of the minimally invasive mitral valve repair learning curve at the institution. Material and methods The indication for the surgery was severe mitral regurgitation. Patients with other valvular insufficiency, body mass index (BMI) > 30 kg/m 2 , ejection fraction (EF) < 45%, aortic dilatation, reoperation, pleural adhesions, coronary artery disease requiring invasive treatment, and pregnant women were disqualified. The patients were assigned to one of three groups regarding their surgery date – group 1 (2012–2013), group 2 (2014–2015) and group 3 (2016–2017). The primary endpoints were death, myocardial infarction, stroke, an reoperation for mitral dysfunction. The investigation was performed to determine preoperative parameters (EuroSCORE, age, sex, BMI, arrhythmias, EF), intraoperative parameters (procedure, cross-clamp, extracorporeal circulation), and postoperative parameters (chest revision, transfusion, drainage, ventilation time, pleurocentesis, hospitalization time). Results There were 173 patients in total. One patient from group 1 (0.6% overall) died. No myocardial infarction or stroke was observed in any of the three groups. Chest revision count (5 vs. 1 vs. 1; p = 0.0004), total drainage (797.20 vs. 517.92 vs. 449.69; p = 0.0018) and hospitalization time (7.89 vs. 7.18 vs. 6.73; p = 0.0005) were significantly different among the groups. The ventilation time, transfusion number and pleurocentesis count did not differ significantly. Conclusions The procedure is safe and ensures optimal perioperative results. The number of complications is low and acceptable.
IntroductionCompleteness of myocardial revascularization is essential in surgical treatment of coronary artery disease. The aim of this study is to determine the effectiveness of coronary endarterectomy as an adjunct to coronary artery bypass grafting (CABG) in the most difficult cases.Material and methodsAmong 1559 patients who had CABG in our department, the cases of 17 who underwent an adjunct left anterior descending endarterectomy were analyzed. All procedures were performed with median sternotomy, extracorporeal circulation and in mild hypothermia (34°C), by the same surgeon. No coronary artery endarterectomy was planned before surgery.ResultsThere was no infarction or cardiac arrest during hospitalization. Only one patient required mechanical circulatory support (intra-aortic balloon counterpulsation). Each patient was contacted and investigation for major adverse cardiac and cerebrovascular events (MACCE) was performed. Eleven patients (65%) already underwent midterm clinical evaluation. There was no death, myocardial infarction or cerebrovascular incident during the entire period (mean follow-up at 15.3 months). One patient required urgent coronarography due to chest pain. No other patient had chest pain or significant deterioration of ventricular function in echocardiography.ConclusionsOutcomes and potential indications for performing left anterior descending coronary endarterectomy as an adjunct to CABG are discussed.
We present a case of a 64-year-old man with coronary artery disease, who underwent a percutaneous coronary intervention of the circumflex artery. As the guidewire was being withdrawn from the target vessel, it became entrapped by the structure of the previously implanted stent. Attempts to retrieve the foreign body were unsuccessful. Changes in electrocardiogram were observed during the procedure, and the level of cardiac biomarkers increased within the next 24-hours. The patient was admitted to the Cardiac Surgery Department. Remnants of the foreign body were removed under visual control using extracorporeal circulation, and coronary artery bypass grafting was performed. Treatment options and outcomes are discussed.
