Minimalinvaziv aortabillentyu-beultetes soran nyert kezdeti tapasztalataink / Minimálinvazív aortabillentyu-beültetés során nyert kezdeti tapasztalataink

Introduction: Due to the aging population, aortic valve stenosis is the most frequently diagnosed acquired cardiac disease amongst adults. Various surgical techniques have been developed and median sternotomy has become the standard practice for exploration. Improvements in cardiological intervention techniques allow surgery to provide the same quality with less invasiveness.Objective: Our aim was to compare the results of the isolated aortic valve surgeries (AVR) performed as either full or partial sternotomy during the study period in terms of pre-, intra-, and postoperative variables.Patients and methods: We examined the results of the isolated AVR performed at Gottsegen National Cardiovascular Center between January 2019 and March 2020 (99 AVR and 151 mini-AVR). During mini-AVR we opened the sternum with J shape ministernotomy up to the 3rd or 4th intercostal space while in median sternotomy we separated the sternum in its total length.Results: Blood consumption (unit) (AVR: 2.90 [2.90]; mini-AVR: 1.85 [2.12]; p<0,05), days of hospitalization (AVR: 9.75 [2.99]; mini-AVR: 8.85 [2.85]; p<0,05) and length of surgery (minutes) (AVR:148.49 [34.4]; mini-AVR: 134.6 [34.8]; p<0,05) were significantly better in the mini-AVR group. In terms of preoperative variables, the two groups were not homogeneous therefore we corrected the strong predictive variables. As a result, levels of bio-statistical significance have disappeared but there is still a trend in favour of minimally invasive surgery.Conclusions: Mini-AVR surgery is considered a more cost-effective intervention compared to standard surgery in terms of less surgical trauma, reduced blood consumption, and shorter operative time.

[Perioperative use of levosimendan in cardiac surgery. Hungarian recommendation]. / A levoszimendán perioperatív alkalmazása a szívsebészetben. Magyar ajánlás.

Low output syndrome significantly increases morbidity and mortality of cardiac surgery and lengthens the durations of intensive care unit and hospital stays. Its treatment by catecholamines can lead to undesirable systemic and cardiac complications. Levosimendan is a calcium sensitiser and adenosine triphosphate (ATP)-sensitive potassium channel (IK,ATP) opener agent. Due to these effects, it improves myocardium performance, does not influence adversely the balance between O2 supply and demand, and possesses cardioprotective and organ protective properties as well. Based on the scientific literature and experts' opinions, a European recommendation was published on the perioperative use of levosimendan in cardiac surgery in 2015. Along this line, and also taking into consideration cardiac surgeon, anaesthesiologist and cardiologist representatives of the seven Hungarian heart centres and the children heart centre, the Hungarian recommendation has been formulated that is based on two pillars: literature evidence and Hungarian expert opinions. The reviewed fields are: coronary and valvular surgery, assist device implantation, heart transplantation both in adult and pediatric cardiologic practice. Orv Hetil. 2018; 159(22): 870-877.

[Right ventricular outflow tract reconstruction in adolescents and adults after previous repair of congenital heart defects]. / A jobbkamra-kifolyási pálya rekonstrukciója elozoleg korrigált veleszületett szívhibák esetén fiatal- és felnottkorban.

UNLABELLED: Due to successful surgical treatment of congenital heart defects in infants and children, the number of patients who reach the adolescent/adult age is continuously increasing. AIMS: The authors sought to identify the short- and medium-term outcomes of reconstruction of right ventricular outflow tract in adolescents and adults who underwent surgical intervention for congenital heart defect in infancy or early childhood. METHODS: Between 2001 and 2012, 48 patients (age: 15-39, mean 21 years) (30 tetralogy of Fallot, 11 pulmonary atresia + ventricular septal defect, 6 transposition of great arteries + ventricular septal defect + left ventricular outflow tract obstruction, and 1 truncus arteriosus) had repeat operation because of right ventricular dysfunction. All patients previously underwent right ventricular outflow tract procedures in early childhood. RESULTS: In 31 patients, the small homograft, and in 9 patients the transannular-paths were replaced for "adult-size" homograft. Bioprosthetic pulmonary valve replacement was performed in pulmonary (6 patients) and homograft annuli (2 patients). In 14 patients, resection of the right ventricular outflow tract aneurism was also necessary to be performed. There was no early and mid-time (10 years) mortality. In 97.5% of patients with homograft-re-implantation, there was no need for repeat intervention for 5 years. CONCLUSIONS: The right ventricular outflow tract restoration in adolescents and adults is an effective procedure. The reconstruction should be performed in early adolescent period to prevent right ventricular dysfunction. The authors prefer using bioprosthetic pulmonary valve replacement in patients with adult-size pulmonary or homograft annulus.

Aortic root reconstruction in a nine-year-old child: a case report.

Aortic root dilatation is present by the age of five years in approximately 35% of patients suffering from Marfan syndrome. However, children rarely undergo surgery for aortic aneurysm and aortic regurgitation during their first decade of life. A nine-year-old boy, who presented with severe aortic regurgitation associated with a 76.8 mm aneurysm of the ascending aorta, underwent a Bentall procedure. Since the aortic annulus was markedly dilated and the cusps were structurally abnormal, the aortic valve was not spared.

[Osteosynthesis with plates for full sternal dehiscence (Titanium Sternal Fixation System Synthes) -- first use in Hungary]. / Teljes sternumdehiscentia miatt alkalmazott lemezes osteosynthesis (Titanium Sternal Fixation System Synthes) elsô magyarországi alkalmazása.

The prevalence of deep sternal infection after cardiac surgery is between 0,5 and 5%, with an average mortality up to 50%. The authors present the case of the rst sternal osteosynthesis carried out in Hungary after postoperative deep sternal infection. Using this orthopedic reconstructive surgical technique in this patient group, an anatomical reconstruction and reposition of the sternum is feasible. With the Titanium Sternal Fixation Synthes system reconstruction of total or partial sternal absence is possible.

[Adult congenital heart program in a tertiary care facility of pediatric cardiology]. / Felnottkori congenitalis szívsebészet gyermekkardiológiai és szívsebészeti központban.

INTRODUCTION: Owing to excellent survival following primary repair over 80% of congenital cardiac patients reach adulthood, half of them requiring continuous specialist care and one-third needing further reoperation. The ample variety and complexity of lesions warrant individualised treatment strategy. OBJECTIVE: This study focuses on grown-up congential heart (GUCH) programme in the settings of a tertiary pediatric cardiac centre. METHODS: Patients underwent corrective surgical procedures in pediatric facilities (theatre, ICU, wards) with a close involvement of adult cardiology/anaesthetic team. Patients were divided into simple/complex groups. RESULTS: Simple group of comprised patients (n = 20) having ASD-II (18/20) sinus venosus ASD (2/20) repair without morbidity/mortality from right subaxillary thoracotomy in 17/20. Complex group (n = 20): corrective surgery for tetralogy of Fallot (6), LVOT-aortic valve repairs (4), allograft conduit exchange (3), TCPC (3), miscellaneous procedures (4) were performed as reoperations in 16/20 at 16.1 +/- 8.1 years following previous operations (median: 1.96, range 1-4). Postoperative right ventricle- (1), acute renal (1) failure and ARDS (1) fully recovered. One patient was lost for multi-organ-failure due to low cardiac output syndrome caused by chronic RV failure. Preoperative cyanosis was a risk factor for postoperative complications (p = 0.01). All survivors are symptom-free. No significant difference in ITU stay/LOS was observed between simple and complex groups. CONCLUSIONS: This study represents the initial experience of authors with GUCH. The number of GUCH patients is expected to rise with an upgrade shift in surgical complexity and severity requiring a multidisciplinary approach. It is advocated that complex GUCH cases should be performed by teams experienced in congenital reconstructive surgery. Patients following complex GUCH procedures have a comparable hospital course to patients undergoing simple cardiac operations.

[Successful surgical correction of tetralogy of Fallot and pulmonary atresia in adulthood after reconsidering inoperability]. / A felnottkori Fallot-tetralogia és pulmonalis atresia sikeres sebészi rekonstrukciója korábbi inoperábilitás úijraértékelése után.

UNLABELLED: A 36 year old male with tetralogy of Fallot and pulmonary atresia was corrected successfully. Previous palliative operation (Cooley shunt) was performed 35 years before. He was in NYHA functional class III. because of chronic hypoxia, polyglobulia, cerebral accident, pulmonary complications, myocardial (ventricular) dysfunction and syncopes. After an uneventful surgical reconstruction, the postoperative period was complicated with haemostasis complication and pulmonary distress syndrome. He left the hospital in NYHA functional class I on the 20th postoperative day in very good condition. CONCLUSION: Complete cardiac recovery will be possible after successful surgically reconstruction of tetralogy of Fallot and pulmonary atresia even in adulthood. The reconsideration of operability of such cases is recommended. As the patient may have different extracardiac complications in every case new complete reconsideration is necessary for the indication of surgical reconstruction.

[Perioperative temporary pacemaker therapy]. / Perioperatív ideiglenes pacemakerkezelés.

INTRODUCTION: Numerous factor can precipitate progression of incomplete heart block to complete heart block in the perioperative period. While there is a consensus of the indications of acute temporary pacing, there is no widely accepted guidelines for the elective perioperative temporary pacing. The indications are clear in the cases of second or third degree atrio-ventricular block, bradycardias, bradyarrhythmias with frequency less than 50/min not responding to atropine, but there are many debate in the cases of first degree atrio-ventricular block with bifascicular or left bundle branch block. Furthermore, during the operation bradyarrhythmia, complete atrio-ventricular block not responding to atropine can develop without any sign on the previous ECG at rest. METHODS AND RESULTS: The authors review the different methods of pacing (transvenous, transcutaneous, transoesophageal), summarize the advantages and disadvantages of each method, the complications and their prevention. Patients' condition, concomitant medical treatment, designed procedures and staffs' experience in the introduction of pacemaker electrode must be considered in questioned cases. CONCLUSIONS: The transcutaneous method is easily performed, don't need a lot of experience. It must be available in every operating theatre and in the questioned cases may be enough until the introduction of the transvenous electrode, if the field of operation make the electrode placement possible.
