          Abstract

          Introduction

          Aortic valve replacement (AVR) is the gold standard in treating symptomatic aortic valve defects. To improve the healing process and limit the trauma, the minimally invasive approach was introduced.

          Aim

          To compare the peri- and post-operative results of aortic valve replacement performed via conventional full sternotomy (con-AVR) and of AVR performed via partial upper sternotomy (mini-AVR).

          Material and methods

          The total study population was divided into 2 demographically homogeneous groups: mini-AVR ( n = 74) and con-AVR ( n = 76). There were no statistically significant differences in preoperative echocardiography.

          Results

          Aortic cross-clamp time and cardiopulmonary bypass time were significantly longer in the mini-AVR group. Shorter mechanical ventilation time, hospital stay and lower postoperative drainage were observed in the mini-AVR group ( p < 0.05). Biological prostheses were more frequently implanted in the mini-AVR group ( p < 0.05). Patients from the mini-AVR group reported less postoperative pain. No significant differences were found in the diameter of the implanted aortic prosthesis, the amount of inotropic agents and painkillers, postoperative left ventricular ejection fraction (LVEF), medium and maximum transvalvular gradient or the number of transfused blood units. There were no differences in the frequency of postoperative complications such as mortality, stroke, atrial fibrillation, renal failure, wound infection, sternal instability, or the need for rethoracotomy.

          Conclusions

          Ministernotomy for AVR is a safe method and does not increase morbidity and mortality. It significantly reduces post-operative blood loss and shortens hospital stay. Ministernotomy can be successfully used as an alternative method to sternotomy.

          Streszczenie

          Wprowadzenie

          Chirurgiczna wymiana zastawki aortalnej (AVR) jest złotym standardem leczenia objawowych wad zastawki aortalnej. Małoinwazyjny dostęp chirurgiczny pomaga zminimalizować uszkodzenie tkanek oraz usprawnia procesy gojenia rany pooperacyjnej.

          Cel

          Porównanie okołooperacyjnych oraz pooperacyjnych wyników leczenia AVR wykonywanej przez sternotomię pośrodkową (con-AVR) oraz poprzez częściową sternotomię górną (mini-AVR).

          Materiał i metody

          Pacjentów włączonych do badania podzielono na dwie demograficznie homogenne grupy: mini-AVR ( n = 74) i con-AVR ( n = 76). Nie było różnic między grupami w wynikach przedoperacyjnego badania echokardiograficznego.

          Wyniki

          Czas zakleszczenia aorty i czas krążenia pozaustrojowego były dłuższe w grupie mini-AVR, w której obserwowano również krótszy czas wentylacji mechanicznej i hospitalizacji oraz mniejszy drenaż pooperacyjny ( p < 0,05). W grupie mini-AVR częściej wszczepiano zastawki biologiczne. Pacjenci z grupy mini-AVR zgłaszali niższe natężenie bólu po operacji ( p < 0,05). Nie obserwowano istotnych statystycznie różnic pod względem średnicy implantowanych zastawek, stosowanych leków inotropowych, leków przeciwbólowych, pooperacyjnej frakcji wyrzutowej, średnich i maksymalnych gradientów zastawkowych oraz ilości przetaczanej krwi pomiędzy grupami. Nie stwierdzono również różnic w występowaniu komplikacji pooperacyjnych, takich jak zgon, udar, migotanie przedsionków, niewydolność nerek, infekcje rany, niestabilność mostka i powtórne otwarcie klatki piersiowej.

          Wnioski

          Ministernotomia jest bezpiecznym dostępem chirurgicznym podczas AVR, który nie zwiększa ryzyka wystąpienia powikłań, w tym zgonu. Mini-AVR znacząco zmniejsza pooperacyjną utratę krwi i skraca czas pobytu w szpitalu. Może być z sukcesem stosowana jako alternatywa dla pełnej sternotomii.

          Cardiopulmonary bypass duration is an independent predictor of morbidity and mortality after cardiac surgery.

          The aim of this study was to determine if there is a direct relationship between the duration of cardiopulmonary bypass (CPB time [CPBT]) and postoperative morbidity and mortality in patients undergoing cardiac surgery. Retrospective study. Cardiac surgery unit, university hospital. Five thousand six patients, New York Heart Association classes 1 through 4, who underwent cardiac surgery between January 2002 and March 2008. All patients were subjected to CPB. The mean CPBT was 115 minutes (median 106). One hundred thirty-one patients (2.6%) died during the same hospitalization. The postoperative median blood loss was 600 mL. Reoperations for bleeding occurred in 193 patients (3.9%), and 1,001 patients received 3 or more units of red blood cells. There were 108 patients (2.2%) with neurologic sequelae, 391 patients (7.8%) with renal complications, 37 patients (0.7%) with abdominal complications, and 184 patients (3.7%) with respiratory complications. Seventy-two patients (1.4%) had an infective complication, and 80 patients (1.6%) had a postoperative multiorgan failure. The multivariate analysis confirmed the role of CPBT, considered in 30-minute increments, as an independent risk factor for postoperative death (odds ratio [OR] = 1.57, p < 0.0001), pulmonary (OR = 1.17, p < 0.0001), renal (OR 1.31, p < 0.0001), and neurologic complications (OR = 1.28, p < 0.0001), multiorgan failure (OR = 1.21, p < 0.0001), reoperation for bleeding (OR = 1.1, p = 0.0165), and multiple blood transfusions (OR = 1.58, p < 0.0001). Prolonged CPB duration independently predicts postoperative morbidity and mortality after cardiac surgery.

            Ministernotomy versus conventional sternotomy for aortic valve replacement: a systematic review and meta-analysis.

            Most aortic valve replacements are by conventional full median sternotomy. Less invasive approaches have been developed with partial upper sternotomy (ministernotomy). Systematic review and meta-analysis were performed with studies comparing ministernotomy and full sternotomy for aortic valve replacement. Twenty-six studies were selected, with 4586 patients with aortic valve replacement (2054 ministernotomy, 2532 full sternotomy). There was no difference in mortality (odds ratio 0.71, 95% confidence interval 0.49-1.02). Ministernotomy had longer crossclamp and bypass times (weighted mean difference 7.90 minutes, 95% confidence interval 3.50-10.29 minutes, and 11.46 minutes, 95% confidence interval 5.26-17.65 minutes, respectively). Both intensive care unit and hospital stays were shorter with ministernotomy (weighted mean difference -0.46 days, 95% confidence interval -0.72 to -0.20 days, and -0.91 days, 95% confidence interval -1.45 to -0.37 days, respectively). Ministernotomy had shorter ventilation time and less blood loss within 24 hours (weighted mean difference -2.1 hours, 95% confidence interval -2.95 to -1.30 hours, and -79 mL, 95% confidence interval -23 to 136 mL, respectively). Randomized studies tended to demonstrate no difference between ministernotomy and full sternotomy. Rate of conversion from partial to conventional sternotomy was 3.0% (95% confidence interval 1.8%-.4%). Ministernotomy can be performed safely for aortic valve replacement, without increased risk of death or other major complication; however, few objective advantages have been shown. Surgeons must conduct well-designed, prospective studies of relevant, consistent clinical outcomes to determine the role of ministernotomy in cardiac surgery.

              Does ministernotomy improve postoperative outcome in aortic valve operation? A prospective randomized study.

              The aim of this study was to compare the postoperative outcome obtained in patients undergoing elective aortic valve operation, either through ministernotomy or conventional sternotomy. Between January 1999 and July 2001, 80 consecutive patients undergoing elective aortic valve replacement were randomly divided into two groups: group I (n = 40 patients) undergoing a ministernotomy approach (reversed-C or reversed-L), and group II (n = 40 patients) undergoing conventional sternotomy. The length of skin incision was significantly shorter in group I than in group II (8.2+/-1.3 cm versus 23.7+/-2.6 cm, p < 0.001). No significant differences were found in cardiopulmonary bypass duration, associated procedures, or aortic cross-clamping times. Total operating time was 3.7+/-0.46 hours in group I compared with 3.4+/-0.6 hours in group II (p = 0.014). A similar incidence of cardiac, neurologic, infective, and renal complications between groups was found. Mean mediastinal drainage and mean blood transfusions (amount of blood transfused) per patient were greater in group II (p < 0.004 and p < 0.001, respectively). Twenty-five (62.5%) patients in group II and 15 (37.5%) patients in group I required postoperative blood transfusion (p = 0.04). Mechanical ventilation time was significantly longer in group II (6.2+/-1.8 hours versus 4.4+/-0.9 hours, p = 0.006). Five days after the surgical procedure, spirometric data analysis demonstrated a significantly lower total lung capacity and maximum inspiratory and expiratory pressures in group II compared with group I (p = 0.003, p = 0.007, and p < 0.001, respectively). Our results showed that ministernotomy had not only important cosmetic advantages but also beneficial effects in blood loss and transfusion, postoperative pain, and probably in sternal stability. Ministernotomy also improved recovery of respiratory function and allowed earlier extubation and hospital discharge.
