Two Different Minimally Invasive Techniques for Female Patients with Atrial Septal Defects: Totally Thoracoscopic Technique and Right Anterolateral Thoracotomy Technique

Impact of right anterolateral thoracotomy with a new approach on breast development: survey analysis of female cardiac surgery patients

INTRODUCTION

Our aim was to present the effects of submammarian thoracotomy by our new approach to breast development in young female patients between 8 and 14 years old.

METHODS

Atrial septal defect closure was performed in 55 female patients between 8 and 14 years old at the time of operation between January 2010 and January 2018 by median sternotomy or right anterolateral thoracotomy. These patients were called for a follow-up visits, breast examination were performed, and a questionnaire of 10 questions was applied.

RESULTS

According to the answer given by the patients to the question of "how would you describe your scar" showed that the surgical method satisfies all patients cosmetically in study group. The overall satisfaction rate for the cosmetic results of operation was 100% versus 41.1%, respectively. The percentage of patients said no to the question "Do you experience lack of self-confidence related your scar" was significantly higher than the control group (p < 0.001). The percentage of those who said yes to the question "Would you like to be operated with the same approach if you will have surgery again?" in the study group was significantly higher than the control group (p = 0.002).

CONCLUSIONS

We consider that our procedure is safe and effective with improved cosmetic results compared to median sternotomy which also confers many advantages such as less trauma, less pain, faster recovery, and shorter hospital stay. This study presents one of the largest series of paediatric patients operated by submammarian thoracotomy.

Outcomes of Three Different Minimal Invasive Approaches for Secundum Atrial Septal Defect Closure: A Single Institute Experience

OBJECTIVE

The aims of this retrospective study were to investigate and evaluate the safety and efficacy of three approaches for closure of secundum atrial septal defect (ASD).

METHODS

In this study, we reviewed clinical data for transcatheter occlusion (TCO, n=63), transthoracic occlusion (TTO, n=55), and right anterolateral minithoracotomy (RALT, n=60) techniques used for ASD closure. We compared the safety and efficacy of the three approaches.

RESULTS

ASD size in the TTO group was similar to that in the RALT group (P=0.645) and significantly larger than that in the TCO group (P<0.001). The RALT group had more non-central types of ASD than the TTO and TCO groups (P=0.019 and P<0.001). The operative time in the TTO group was shorter than that in the TCO and RALT groups (P<0.001 and P<0.001). The ventilation time and intensive care unit duration were shorter in the TTO group than in the RALT group (P<0.001 and P<0.001). Hospital duration in the TCO group was shorter than that in the TTO and RALT groups (P<0.001 and P<0.001). There were no residual shunt and mortality in any group in hospital or during follow-up. There was no significant difference in the incidence of total complications among the three groups (P=0.738).

CONCLUSION

TCO, TTO, and RALT can be performed with favorable cosmetic and clinical results for closing ASD. Appropriate patient selection is an important factor for successful closure. These techniques are promising alternatives to standard median sternotomy and merit additional study.

Triport periareolar thoracoscopic surgery versus right minithoracotomy for repairing atrial septal defect in adults

OBJECTIVES

Our goal was to investigate the safety and feasibility of triport periareolar thoracoscopic surgery (TPTS) and its advantages in repairing adult atrial septal defect.

METHODS

Between January 2017 and January 2020, a total of 121 consecutive adult patients underwent atrial septal defect closure in our institution. Of these, 30 patients had TPTS and 31 patients had a right minithoracotomy (RMT). Operational data and clinical outcomes were compared between the 2 groups.

RESULTS

The total operation time, cardiopulmonary bypass time and aortic cross-clamp time in the TPTS group were slightly longer than those in the RMT group, but there were no differences between the 2 groups. Compared with the RMT group, the TPTS group showed a decrease in the volume of chest drainage in 24 h (98.6 ± 191.2 vs 222.6 ± 217.2 ml; P = 0.032) and a shorter postoperative hospital stay (6.5 ± 1.5 vs 8.0 ± 3.7 days; P = 0.042). The numeric rating scale on postoperative day 7 was significantly less in the TPTS group than in the RMT group (2.82 ± 1.14 vs 3.56 ± 1.42; P = 0.034). The patient satisfaction scale for the cosmetic results in the TPTS group was significantly higher than in the RMT group (4.68 ± 0.55 vs 4.22 ± 0.76; P = 0.012). No differences were found in postoperative complications. No in-hospital death or major adverse events occurred in the 2 groups.

CONCLUSIONS

TPTS is safe and feasible for the closure of adult atrial septal defect. Compared with RMT, it has been associated with less pain and better cosmetic outcomes.

Early and mid-term outcomes of total repair of tetralogy of Fallot through a right subaxillary thoracotomy

OBJECTIVES

We aimed to investigate the safety, feasibility and early and mid-term outcomes of total repair of elective tetralogy of Fallot through a right subaxillary thoracotomy.

METHODS

Between May 2010 and September 2015, a retrospective review of patients with elective tetralogy of Fallot undergoing primary repair through a right subaxillary thoracotomy was performed. This study included 47 patients [27 males, 20 females; the mean age of 1.7 ± 1.5 years (ranging from 3 to 106 months); body weight of 9.7 ± 2.8 kg (ranging from 5 to 16 kg); McGoon ratio ≥1.5]. The ventricular septal defects were approached through a right atriotomy in 30 patients, a right ventriculotomy in 8 patients and the combination of a right atriotomy and ventriculotomy in 9 patients. Transannular and non-transannular patches were used in 20 and 27 patients, respectively.

RESULTS

There was 1 operative death (2.1%), and the others recovered uneventfully. The median cardiopulmonary bypass and aortic cross-clamping times was 79 ± 20.8 (45-136) and 50 ± 15.7 (25-94) min, respectively. The mechanical ventilation time, length of intensive care unit and postoperative hospital stay were 0.9 ± 0.6, 2.6 ± 1.1 and 10.7 ± 2.7 days, respectively. The main complications involved low cardiac output syndrome in 5 patients, arrhythmia in 6 patients, pulmonary infection in 4 patients, small residual shunt in 2 patients, mild residual right ventricular outflow tract obstruction in 2 patients, mild tricuspid regurgitation in 3 patients and atelectasis in 1 patient. The mean follow-up time was 82 ± 22.0 months, and no late deaths occurred during the follow-up. One (2.1%) patient received reintervention for residual significant pulmonary artery stenosis. That was in addition to 2 (4.3%) patients having mild residual right ventricular outflow tract, 1 (2.1%) patient with moderate tricuspid regurgitation and 3 (6.4%) patients with moderate pulmonary valve regurgitation to be followed up.

CONCLUSIONS

The right subaxillary thoracotomy, providing a safe and feasible alternative, can be performed with a low mortality rate and satisfactory early and mid-term outcomes for total repair of elective tetralogy of Fallot.

Comparative Study between Surgical Repair of Atrial Septal Defect via Median Sternotomy, Right Submammary Thoracotomy, and Right Vertical Infra-Axillary Thoracotomy

Objective

To compare the results of surgical repair via median sternotomy, right submammary thoracotomy, and right vertical infra-axillary thoracotomy for atrial septal defect (ASD).

Methods

This is a retrospective analysis of the relative perioperative and postoperative data of 136 patients who underwent surgical repair for ASD with the abovementioned three different treatments in our hospital from June 2014 to December 2017.

Results

The results of the surgeries were all satisfactory in the three groups. No statistically significant difference was found in operative time, duration of cardiopulmonary bypass, blood transfusion amount, postoperative mechanical ventilation time, duration of intensive care unit, length of hospital stay, and hospital costs. However, the median sternotomy group had the longest incision. Meanwhile, there was no significant difference in postoperative complications.

Conclusion

All three types of surgical incisions can be safely and effectively used to repair ASD. The treatments via right submammary thoracotomy and right vertical infra-axillary thoracotomy have advantages over the treatment via median sternotomy in cosmetic results and should be the recommended options.

No-touch aorta robot-assisted atrial septal defect repair via two ports

OBJECTIVES

Atrial septal defect (ASD) repairs have been successfully performed on arrested hearts with robotic assistance. The present study assessed the feasibility, safety, and efficacy of totally endoscopic cardiac surgery using a no-touch aorta technique for ASD via only 2 ports, and we named this procedure two-port robotic cardiac surgery (TROCS).

METHODS

Between May 2014 and June 2016, 8 consecutive patients underwent TROCS for ASD using the da Vinci surgical system (Intuitive Surgical Inc.) at our institute. All of the procedures were performed via only 2 port incisions in the right chest. One was the camera port, and the other was the port for the robotic instruments. Both robotic instruments were inserted through this port and crossed while being prevented from colliding with each other. The surgeon console was set to the reverse of default settings so that both masters would control the inverse instrument. TROCS for ASD was carried out under ventricular fibrillation induced by combinations of an electrical fibrillator, injection of potassium, and hypothermia without aortic cross-clamping.

RESULTS

All cases were successfully repaired. The mean operation, cardiopulmonary bypass and ventricular fibrillation times were 129.6 ± 29.0 min, 66.9 ± 24.5 min and 9.6 ± 5.9 min, respectively, and the estimated blood loss volume was 28.1 ± 58.6 ml. No patients required blood transfusion during their hospital stay, and their cosmetic results were excellent.

CONCLUSIONS

TROCS for ASD using no-touch aorta technique was achieved safely with good clinical results and excellent cosmetic results.
