Methods: A retrospective descriptive study of the use of self-suture branching artificial vessels in aortic arch surgery at Hanoi Heart Hospital from October 2018 to May 2021. Results: There were 33 cases of aortic arch replacement using self-suture branching artificial vessels. The rate of postoperative bleeding was 6.06%. The rate of artificial vessel infection is 0%. Conclusion: Using self-suture branching artificial vessels in aortic arch surgery is a safe and effective technique.

Outcomes of surgical treatment of Stanford type of aortic dissection at Hanoi Heart Hospital in the period 2015-2020

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.

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.

Surgical treatment of left-sided infective endocarditis in Hanoi Heart Hospital

Objective: to evaluate the short-term outcomes of surgical treatment of left-sided infective endocarditis (IE) in Hanoi Heart Hospital. Patients and Methods: A retrospective, cross-sectional and descriptive study on all patients underwent surgery for left-sided IE from 3/2015 to 3/2019 in Hanoi Heart Hospital. Result: 56 patients underwent surgery for left-sided IE in 4 years; the mean age was 45.8 ± 16.0; male-female ratio was 3.3/1. 9 patients (16.1%) had prosthetic valve endocarditis. Preopeative blood cultures were positive in 35.7%, the mainly microorganism was Streptococcus (21.4%). Emergency and urgent surgery was performed in 14.3%; the most frequently postoperative complication was kidney failure, the in-hospital mortality rate was 5.4%. During the average follow-up time of 36.6± 14.2 months, the recurrence rate of IE was 17.8%. Conclusion: surgical treatment of left-sided infective endocarditis is still a great challenge, the early recurrence and motality rate are high.

Clinical and laboratory testing of oral anticoagulation therapy vitamin k antagonists at the emergency department of Hanoi Heart Hospital

Background: The most commonly used oral anticoagulant is acenocoumarol with the brand name is Sintrom and recently, warfarin with the brand name is Coumadin has begun to be used. Anticoagulation with vitamin K antagonists faces two main obstacles: the narrow therapeutic range and the effectiveness of the drug varies by many factors. Objective: " Current status of coagulation disorders in the treatment of anticoagulants with vitamin K antagonists. Understanding some factors affecting the goal of anticoagulant treatment". Method: Cross-sectional, retrospective, descriptive analysis of drug use and influencing factors of patients diagnosed with coagulopathy admitted to the emergency department at Hanoi Heart Hospital from April 2020 to August 2021. Results: There were 675 patients admitted to the hospital with blood clotting disorders. The average age is 60,17±10,13, the youngest is 30, the oldest is 90; 63 patients, accounting for 9.42%, need to be hospitalized for inpatient treatment; There are 108 patients, accounting for 16%, with bleeding and 18 patients, accounting for 2.7%, with thromboembolism or valve obstruction. Conclusion: Coagulation disorders during treatment with vitamin K antagonist anticoagulants is a common condition in the emergency department. However, the complication rate is not high. There are many factors that affect the patient's treatment goals and the drug use is a fairly common factor.

Comments of results after surgical replacement of mechanical mitral and aortic valve in children at Hanoi Heart Hospital

Objective: Assessment of early results after surgical treatment of mechanical mitral valve and aortic valve replacement in children at Hanoi Heart Hospital from 2004 to June 2019. Methods: Analysis and evaluation based on data collected from patients undergoing surgery and from the results of follow-up examination. Results: The total number of patients was 50, in which 34 cases of simple mechanical mitral valve replacement, 16 cases of simple mechanical aortic valve replacement. Average age of surgery: 7.58 ± 6.01 years (The lowest age is 7 months, the highest is 15 years). Male: 29 patients (58%), female: 21 patients (42%). Ultrasound before discharge and after 3 months, we found similar results: mean EF: mechanical mitral valve: 56.28 ± 10.67 %; Aortic valve: 54.72 ± 9.66% .Mean pressure : Mitral valve: 3.18 ± 1.25; Aortic valve: 12.12 ± 3.25 mmHg. INR index: mitral valve : 2.58 ± 1.20; Aortic valve: 2.34 ± 0.92. Complications of valve replacement: 2 cases of mitral valve replacement after surgery 3 years and 4 years; There was 1 case of aortic valve 5 years after surgery. Death immediately after surgery: mitral valve: 2 cases (5.88%); aortic valve: 1 case (6.25%); Late death: After 2 years, there was 1 case of death after mitral valve replacement; After 4 years, there was 1 case of death after aortic valve replacement. Conclusion: The results of heart valve replacement surgery in children are positive. It is necessary to have better equipment and experience in open heart surgery in low-birth-weight children in order to operate the disease as early and effectively as possible, in which the treatment of complications of heart failure and post-operative coagulopathy should be considered important.

Prognostic factors of cerebral revascularisation in acute ischemic stroke at Hanoi Heart Hospital

Background: Considering the effectiveness of treatment for acute ischemic stroke (AIS)patients, the most expected method is immediate revascularization using intravenous thrombolysis or mechanical thrombectomy, or both methods. Objective: “Find factors related to post-treatment outcomes of acute ischemic stroke patients undergoing cerebral revascularization”. Method: Cross-sectional, prospective, descriptive analysis with convenient sample size. Results: From February 2018 to August 2021, 83 patients were hospitalized with a diagnosis of acute ischemic stroke or acute ischemic stroke and had cerebral revascularision either by thrombolysis or mechanical devices or both. 6.02% of them had cerebral thrombosis with mechanical devices and stenting of cerebral/carotid arteries. Mean age was 66.37±11.82 (range 31to 91 years). Mean NIHSS score was 12.57±6.70. The rate of complete recanalization was 91.56%. The mRS score of 0-2 points accounted for 48.19% at the time of discharge and 54.21% at 30 days after discharge. The rate of death or severe illness at discharge accounted for 14.45%. 30 days all-cause mortality after discharge accounted for 25.3%. Conclusion: The rate of complete reperfusion in patients with acute cerebral infarction at Hanoi Heart Hospital and good recovery rate is quite high. Factors that related to the treatment efficacy of patients with acute ischemic stroke were NIHSS score, ASPECT score, occlusion site, pre-reperfusion parenchymal damage and the selection of appropriate reperfusion measures.
