Comprehensive comparison of carotid endarterectomy primary closure and patch angioplasty: A single-institution experience

Background: Carotid endarterectomy (CEA) is an effective intervention for the treatment of high-grade carotid stenosis. Technical preferences exist in the operative steps including the use patch for arteriotomy closure. The goals of this study are to compare the rate of postoperative complications and the rate of recurrent stenosis between patients undergoing primary versus patch closure during CEA. Methods: Retrospective chart review was conducted for patients who underwent CEA at single institution. Vascular surgeons mainly performed patch closure technique while neurosurgeons used primary closure. Patients’ baseline characteristics as well as intraprocedural data, periprocedural complications, and postprocedural follow-up outcomes were captured. Results: Seven hundred and thirteen charts were included for review with mean age of 70.5 years (SD = 10.4) and males representing 64.2% of the cohort. About 49% of patients underwent primary closure while 364 (51%) patients underwent patch closure. Severe stenosis was more prevalent in patients receiving patch closure (94.5% vs. 89.4%; P = 0.013). The incidence of overall complications did not differ between the two procedures (odds ratio = 1.23, 95% confidence intervals = 0.82–1.85; P = 0.353) with the most common complications being neck hematoma, strokes, and TIA. Doppler ultrasound imaging at 6 months postoperative follow-up showed evidence of recurrent stenosis in 15.7% of the primary closure patients compared to 16% in patch closure cohort. Conclusion: Both primary closure and patch closure techniques seem to have similar risk profiles and are equally robust techniques to utilize for CEA procedures.

An Alternative Technique of Intraoperative Identification of Multiple Muscular Ventricular Septal Defects

We propose the passage of a thick black braided silk SUTUPAK silk suture (Ethicon, Somerville, NJ) through the additional muscular ventricular septal defects to facilitate patch closure of the multiple muscular ventricular septal defects.

Early results of total endoscopic closure for atrial septal defect in children at Cardiovascular Center, E Hospital, Hanoi, Viet Nam

Introduction: Atrial Septal Defect is the most common congenital heart disease. Minimally invasive cardiac surgery is being perfomed routinely at several cardiovascular centers in Vietnam. At E Cardiovascular Center, from 2016 to 2019, we performed total endoscopic closure for atrial septal defect in children using 4 trocars. From 2020 to present, we have reduced the number of trocars to three. This report was to evaluate the effectiveness and early results of total endoscopic closure with 3 trocars for atrial septal defect in children. Method: Twelve children underwent ASD closure from 1/2020 to 5/2021, with mean age of 7.7 years old (range from 2.5 to 11); mean weight was 20.8 kilograms (range from 12 to 40). All the patients underwent the operation with peripheral cardiopulmonary bypass (CPB). Result: The mean peripheral circulation time was 70 minutes (range from 56 to100 minutes) on beating hearts. There were 8 cases with patch-closure and 4 cases with direct-closure. After operations, we reexamined by echocardiography, the atrial septal defects were closed completely with no residual shunt, the common femoral arteries at the cannula position were normal and no stenosis were present. Conclusion: Totally endoscopic closure for ASD on beating hearts with 3 trocars is save with a very good short-term results.

Pseudoaneurysm of the sinus of Valsalva caused by infective endocarditis in a 7-year-old child with congenital heart disease

We report a case of a pseudoaneurysm in the sinus of Valsalva, secondary to infective endocarditis in a child with trisomy 21. The patient had a history of subaortic stenosis, bicuspid aortic valve, and ventricular septal defect. Patch closure of the ostium of the pseudoaneurysm and aortic valve replacement was performed. The patient was discharged without severe complications.

Takayasu’s arteritis with giant left ventricular pseudoaneurysm presenting as heart failure

Takayasu’s arteritis (TA) is a vasculitis with a predilection for young women. Left ventricular pseudoaneurysm (PSA) in TA is a rare phenomenon. We report a 36 years old Filipina who presented with heart failure symptoms. Years prior, she had a recurrent fever, headache, myalgia and left arm claudication. On workup, a 2D echo revealed a left ventricular PSA with mural thrombus and moderate mitral regurgitation. Cardiac MRI further characterised the PSA with a sac diameter of 8×7.5×8.4 cm (CC×T×AP). Carotid Duplex Scan revealed total occlusion of the mid to distal right common carotid artery and left subclavian artery. She was started on immunosuppresants and guideline-directed medical therapy (GDMT) for heart failure and subsequently underwent successful endoventricular patch closure and mitral valve repair. This case highlights the importance of actively searching for cardiac complications of TA which although very rare, can dominate the clinical picture and may carry a dismal prognosis if left untreated.

Mechanophysiologically active patch for closure of atrial septal defect

Closure of atrial septal defects (ASDs) can be achieved by various methods right from direct closure to patch closure using various materials viz. pericardium, Dacron and Teflon, to device closure using percutaneous techniques. Although percutaneous techniques are the most commonly practised method in developed countries, a subset of patients will require surgical closure. Various patch materials have been used for long, but all of them have some complications and risks associated with them. We report a case of novel technique of ASD closure done using a pedicled, vascularised and contractile right atrial wall flap.

Resolution of post-anaesthesia aortic regurgitation by repair of a ruptured sinus of Valsalva aneurysm: 5 case reports

Background Ruptured sinus of Valsalva aneurysm (SVA) is a rare cardiovascular disease in which some patients exhibit aortic valve insufficiency. SVA repair and valve replacement are usually required for treatment. Here, we report 5 cases of ruptured SVA with severe post-anaesthesia aortic regurgitation (AR). To the best of our knowledge, this is the first report of ruptured SVA with severe post-anaesthesia AR. Case presentation: From 2018 to 2020, there were 5 cases of ruptured SVA with severe AR after anaesthesia in our hospital. The main symptoms were palpitation and shortness of breath. Transthoracic echocardiography (TTE) with colour-flow Doppler showed ruptured aortic sinus aneurysms without AR. Post-anaesthesia echocardiography showed severe AR. Direct patch closure of the ruptured aneurysm resolved the left-to-right shunt and AR, and the aortic valve was not replaced. Conclusions Post-anaesthesia AR without obvious structural defects may occur in patients with ruptured SVAs. Valve replacement may not be necessary.

Aorto-left ventricular tunnel: case series of a rare disease

Introduction: Aorto-left ventricular tunnel is a rare disease that can cause significant morbidity early in life due to volume overload and left ventricular failure. Surgical intervention is usually curative with minimal early complications. However, long-term effects and outcome are not fully determined. Objective: We are reporting a case series of this rare CHD with its long-term outcome. Methods: We conducted a retrospective analysis of all children from birth to 14 years of age who were admitted between 2001 and 2020 with the diagnosis of aorto-left ventricular tunnel. Demographic, echocardiographic, and perioperative data were collected and reviewed. The pre-operative data were compared with data reviewed on the last outpatient follow-up. Results: Total of five patients fulfilled our inclusion criteria. Three patients were diagnosed after auscultating an incidental murmur, one had symptoms of congestive heart failure, and one had an abnormal fetal echocardiogram. Echocardiography demonstrated stenotic and regurgitant aortic valve with severely depressed left ventricle function in two patients, one of them with also single left coronary artery. The other three patients had normal aortic valve structure and normal ventricular function. All five patients had surgical repair, two by patch closure at aortic end of aorto-left ventricular tunnel, two by patch closure at both aortic and left ventricular ends, and one by aortic root replacement using a homograft. During follow-up, there was no residual aorto-left ventricular tunnel in any of our five cases, two had moderate aortic regurgitation and one had moderate residual aortic stenosis. Conclusions: Spectrum of presentation for aorto-left ventricular tunnel varies from an occult lesion to frank left heart failure due to volume or less commonly, pressure overload. Early surgical repair is recommended and is usually associated with complete resolution. Long-term follow-up is recommended for aortic root dilatation and aortic valve competency, as valve function need to be addressed in a timely manner to avoid further complications.
