Introduction: Type A aortic dissection (AADA) requires emergency surgery with different options including valve-sparing aortic root replacement (VSRR), supracoronary ascending aorta replacement (SCR) and aortic valve and root replacement (AVRR). Recurrence of aortic regurgitation (AR) and extent of left ventricular (LV) remodeling in patients with AADA was compared between these surgical techniques. Methods: A total of 120 patients (59 ± 12 years, 63% male) with AADA who underwent VSRR (n=22), SCR (n=62) or AVRR (n=36) were included in the present retrospective evaluation. AR grade and LV volumes and ejection fraction were assessed postoperatively (before hospital discharge) and during follow-up. Estimated marginal means ± standard error of the mean were obtained using linear mixed models. Results: Patients who underwent VSRR were significantly younger (49 ± 6 years) and more often male (84%). There were more patients in SCR group with hypertension compared to VSRR and AVRR (67% vs. 27% and 47%; p=0.006). The EuroSCORE II was highest in patients who underwent AVRR. After a median follow up of 53 months, the mean AR grade was 1.2 ± 0.2 in VSRR vs. 1.8 ± 0.2 in SCR vs. 0.2 ± 0.1 in AVRR (p<0.001). LV end-diastolic and end-systolic volumes remained stable in VSRR, while a significant increase was observed in SCR (table). The ejection fraction remained stable in all groups, however, a trend towards improvement was observed in VSRR (p=0.055). Conclusions: Patients with AADA who underwent SCR experienced more AR compared to AVRR resulting in larger LV volumes during follow up. Despite higher AR grade during follow up in patients who underwent VSRR compared to AVRR; there was no deterioration in LV volumes and function after VSRR.

Background: Stanford type A aortic dissection is a complex disease and a serious surgical emergency. The diagnosis is determined based on diagnostic imagines. Surgery is the mainstay of treatment, with high mortality and morbidity. This study aimed to comment on clinical and paraclinical characteristics and evaluate the results of surgical treatment of type A aortic dissection at Hanoi Heart Hospital within 5 years from 2015 to 2020. Methods: Retrospective and descriptive study of patients diagnosed with type A aortic dissection who were surgically treated at Hanoi Heart Hospital from January 2015 to May 2020. Results: 109 cases were included in the study with the mean age of 56.0 ± 14.4; 50 - 60 age accounted for the highest percentage (30.3%); men accounted for 67.9%. Classic type A aortic dissection in 95 cases (87.2%). Chest pain was the main clinical symptom (91.7%); 4.6% came to the hospital in a state of cardiogenic shock and circulatory arrest. The rate of Marfan phenotype was 13.8%. The most common surgery is replacing the ascending aorta (45.9%); total replacement of the aortic arch accounted for 17.4%; Total root replacement and aortic arch accounted for 3.7%. The average aortic pairing time was 120.7 ± 41.0 minutes, the mean running time was 179.7 ± 57.0 minutes. Re-operative bleeding accounted for 6,4%; cerebrovascular accident accounted for 2,8%. The early mortality rate after surgery was 9.2%. The mean follow-up time was 24.93 ± 16.13 months, the mean survival time was 52.0 ± 1.9 months, the survival rate was 88.1% after 1 year and 85.3% after 5 years. Conclusion: Early mortality, postoperative complications and survival rate after follow-up were positive with surgical technique and conditions of anesthesia and resuscitation at Hanoi Heart Hospital.

Abstract Funding Acknowledgements None Aim Different surgical techniques are available for mitral valve (MV) repair in patients with degenerative severe mitral regurgitation (MR). Leaflet resection (LR) and neochordoplasty (NP), both including ring annuloplasty (RA), are the most frequently performed techniques for posterior mitral leaflet prolapse/flail repair. Despite NP technique is supposed to preserve LV physiology more than LR, it is unclear which technique provides the best haemodynamic pattern. In the present study, the results of the two different surgical techniques in terms of left ventricular (LV) dimension and function are investigated. Methods 23 consecutive patients who underwent MV surgical repair were enrolled. All patients underwent, before surgery and after 8 ± 2 months, 2D and 3D echocardiography with automatic (Heart Model, Philips) assessment of LV volumes and ejection fraction (EF), left atrial (LA) volume, right ventricular (RV) dimension and function, pulmonary artery systolic pressure (PASP), MR, tricuspid regurgitation (TR) and MVPG quantification. MR was corrected using 1) NP with polytetrafluoroethylene sutures and 2) triangular LR, both with RA. Patients were divided in 2 groups according to the surgical technique. Results: techniques were able to successfully correct MR. There were no significant differences in baseline echocardiogram and demographic characteristics between the two groups. There were no significant differences in terms of post-surgical MVPG between the two groups. In all patients a trend in reduction in LV dimension at follow-up was observed, but it was statistically significant only in NP patients (pre-surgical EDV 150 ± 41 VS post-surgical EDV 100 ± 27 ml, p = 0.03). Conclusions Both MV repair techniques showed a successful MV repair and an improvement in LV volumes at follow-up, especially in NP group. Further perspective studies are necessary to demonstrate the hypothesis of more physiological haemodynamic pattern associated with NP techniques.

Background: Type A aortic dissection is a challenging surgical emergency associated with high morbidity and mortality. Many techniques have evolved to repair the dissected sinus segments and restore aortic valve dynamics. Herein, we evaluate the early outcome of a novel technique for reconstruction of dissected aortic root. Methods: A prospective study was conducted on 300 patients to evaluate the early results of repair of dissected root in type A aortic dissection. The mean age was 59.65±8.52 years, and 76% of patients were males. All patients had four standard steps for aortic reconstruction: 1) commissural resuspension; 2) right coronary sinus reinforcement with pericardial and Dacron bands; 3) non-coronary sinus reinforcement using external Dacron patch; 4) circumferential inversion of adventitial layer of the root. Patients were followed up clinically, echocardiographically, and by CT scan. Results: The in-hospital mortality was 8%. The mean cross-clamp time was 120±30 minutes, and circulatory arrest time was 25+10 minutes. Twenty-seven patients (9%) experienced postoperative complications, including bleeding and acute kidney injury. During a mean follow-up time of 48±12 months, there were no recurrent aortic dissection, aortic dilatation, pseudoaneurysm, or progression of aortic regurgitation during the entire study period. Conclusions: This reconstructive technique technically is undemanding, feasible, safe, and durable with good early results. A larger cohort of patients with longer period of follow up should generate a more powerful evaluation of this technique.

Background: BNP testing is now common though it is not clear if the test results are used to improve patient care. A high BNP may be an indicator that the left ventricular ejection fraction (LVEF) is low (<40%) such that the patient will benefit from life-prolonging therapy. Objective: To determine how often clinicians obtained a measure of LVEF (echocardiography, nuclear) following a high BNP value when the left ventricular ejection fraction (LVEF) was not known to be low (<40%). Methods and Results: We reviewed the medical records of 296 consecutive patients (inpatient or outpatient) with a BNP values of at least 200 pg/ml at a single medical center (tertiary hospital with 8 community clinics). A prior diagnosis of heart failure was made in 65%, while 42% had diabetes, 79% had hypertension, 59% had ischemic heart disease and 31% had chronic lung disease. The mean age was 73 ± 12 years, 75% were white, 10% black, 15% other and the mean BNP was 810 ± 814 pg/ml. The LVEF was known to be < 40% in 84 patients (28%, mean BNP value of 1094 ± 969 pg/ml). Of the remaining 212 patients without a known low LVEF, 161 (76%) had a prior LVEF >=40% ( mean BNP value of 673 ± 635 pg/ml), and 51 (24%) had no prior LVEF documented (mean BNP 775 ± 926 pg/ml). Following the high BNP, a measure of LVEF was obtained (including outside studies documented by the primary care provider) within 6 months in only 53% (113 of 212) of those with an LVEF not known to be low. Of those with a follow-up echocardiogram, the LVEF was <40% in 18/113 (16%) and >=40% in 95/113 (84%). There was no significant difference in mean initial BNP values between those with a follow-up LVEF <40% (872 ± 940pg/ml), >=40% (704 ± 737 pg/ml), or not done (661 ± 649 pg/ml, p=0.5). Conclusions: Follow-up measures of LVEF did not occur in almost 50% of patients with a high BNP where the information may have led to institution of life-prolonging therapy. Of those that did have a follow-up study a new diagnosis of depressesd LVEF was noted in 16%. Screening of existing BNP and LVEF data and may be an efficient strategy to identify patients that may benefit from life-prolonging therapy for heart failure.

Abstract OBJECTIVES The aim of this study was to investigate the clinical outcomes and follow-up results among 5 main aortic arch surgery methods for type A aortic dissection in a single centre. METHODS From 2002 to 2018, 958 type A aortic dissection patients who received surgical repair were divided into 5 groups according to the arch surgery method: hemiarch replacement (n = 206), island arch replacement (n = 54), total arch replacement with frozen elephant trunk (n = 425), triple-branched stent (n = 39) and fenestrated stent (n = 234). The indications for the different arch methods were related to the patient’s preoperative status, the location and extent of the dissection and the surgical ability of the surgeons. A comparative study was performed to identify the differences in the perioperative data, and the Kaplan–Meier analysis was used to assess the long-term survival and reintervention rates. Thirty matched surviving patients that were included in each group completed Computed tomography angiography to determine long-term reshaping effect. RESULTS The 30-day mortality rate was 15.8%, and there was no difference among the 5 groups (P = 0.848). The follow-up survival rates were similar among the 5 groups (P = 0.130), and the same was true for patients without reintervention (P = 0.471). In the propensity matching study, patients with stents (frozen elephant trunk, triple-branched stent, fenestrated stent) had a slower aortic dilation rate and a higher ratio of thrombosis in the false lumen at the descending aortic and abdominal aortic levels than patients without stents. CONCLUSIONS No standard method is available for arch surgery, and indications and long-term effects should be identified with clinical data. In our experiences, simpler surgical procedures could reduce mortality in critically ill patients and stents in the distal aorta could improve long-term reshape effects.

Successful treatment of type A acute aortic dissection depends on the promptness of diagnostic evaluation and therapy. Fast diagnosis can be challenged by numerous complications such as myocardial ischemia, acute aortic insufficiency, and disturbances in organ perfusion and pericardial tamponade. The authors report the case history of a 72-year-old woman, who was admitted after resuscitation with ST segment elevation. Echocardiography revealed acute type A aortic dissection with signs of pericardial tamponade. An emergency operation consisting of the resection of the ascending aorta and the reconstruction of the aortic root was performed, which took six hours from admission until the end of the operation. Follow-up examinations demonstrated good left ventricular function and competent aortic valve. The authors propose that with the development of diagnostic and therapeutic options, faster and less invasive interventions will be introduced in near future for the treatment of acute aortic dissection, which may reduce the morbidity and mortality rates of this lethal illness.
