Abstract Background Tetralogy of Fallot (TOF) is one of the most common cyanotic congenital heart diseases. Pulmonary regurgitation is the most common and severe comorbidity after transannular patch (TAP) repair of TOF patients. It has not been confirmed whether a TAP repair with monocusp valve reconstruction would benefit TOF patients in perioperative period compared to those without monocusp valve reconstruction. The purpose of the study is to review and analyze all clinical studies that have compared perioperative outcomes of TOF patients undergoing TAP repair with or without monocusp valve reconstruction and conduct a preferable surgery. Methods Eligible studies were identified by searching the electronic databases. The year of publication of studies was restricted from 2000 till present. The primary outcome was perioperative mortality, and secondary outcomes included cardiopulmonary bypass time, aortic cross-clamp time, ventilation duration, ICU length of stay, hospital length of stay, perioperative right ventricular outflow tract (RVOT) pressure gradient, and moderate or severe pulmonary regurgitation (PR). The meta-analysis and forest plots were drawn using Review Manager 5.3. Statistically significant was considered when p-value ≤ 0.05. Results Eight studies were included which consisted of 8 retrospective cohort study and 2 randomized controlled trial. The 10 studies formed a pool of 526 TOF patients in total, in which are 300 undergoing TAP repair with monocusp valve reconstruction (monocusp group) compared to 226 undergoing TAP repair without monocusp valve reconstruction (non-monocusp group). It demonstrated no significant differences between two groups in perioperative mortality (OR = 0.69, 95% CI 0.20–2.41, p = 0.58). It demonstrated significant differences in perioperative cardiopulmonary bypass time (minute, 95% CI 17.93–28.42, p < 0.00001), mean length of ICU stay (day, 95% CI − 2.11–0.76, p < 0.0001), and the degree of perioperative PR (OR = 0.03, 95% CI 0.010.12, p < 0.00001). Significant differences were not found in other secondary outcomes. Conclusion Transannular patch repair with monocusp valve reconstruction have significant advantages on decreasing length of ICU stay and reducing degree of PR for TOF patients. Large, multicenter, randomized, prospective studies which focuse on perioperative outcomes and postoperative differences based on long-term follow-up between TAP repair with and without monocusp valve reconstruction are needed.

Background: A prospective study was conducted on 100 patients of perforation peritonitis: To find out the incidence of gastro intestinal perforation in various age groups, sex, riral or urban, socio economic status, To find out the various causes and sites of gastra intestinal perforartions, To determine various types of procedures being done to treat gastro intestinal perforations.Methods:The study population consisted of 100 patients of perforation peritonitis admitted at surgical wards of Rajindra Hospital, Patiala. Patients underwent necessary investigations such as Blood counts, biochemical analysis and urine analysis. X-ray Abdomen and chest / USG Abdomen/Pelvis CT-Abdomen (as and when required). All diagnosed patients were subjected to surgery. In all cases, operative findings and postoperative course were followed up for three months. Final outcome was evaluated on the basis of clinical, operative and radiological findings. In pre-pyloric and duodenal perforation, GRAHAM’S PATCH REPAIR carried out. In Ileal and Jejunal perforations, primary closure or exteriorization done depending upon the condition of the gut and duration of the symptoms. The patient outcome was assessed by duration of hospital stay, wound infection, wound dehiscence, leakage/entero-cutaneous fistula, intra-abdominal collection/abscess, ileostomy related complications and reoperation. Wound infection was graded as per SSI grading.Results:Most common age group for perforation was 21-40 years (50%) followed by 41-60 (33%) years in present study. Mean age of the patients is 37.91 + 13.15 years with male predominance (78%) in our study. 4% of the patients were of upper socio-economic status while 32% of the patients were of middle and 64% of the patients were of lower socio-economic status.Abdominal pain was seen in 100% of the patients while abdominal distension was present in 69% of the patients. Nausea/Vomiting was seen in 61% of the patients while Fever and Constipation was seen in 53% and 86% of the patients respectively. Diarrhoea was seen in 3% of the patients. Tenderness, guarding & rigidity, distension, obliteration of liver dullness and evidence of free fluid were present in 100% of the patients. Bowel sounds were not detected in all the patients. Most common perforations were Duodena(37%), Ileal (25%), Gastric (25%) followed by Appendicular (9%), Jejunal (4%) and Colonic perforation (2%). The most common etiology of gastrointestinal perforations was Peptic ulcer followed by Typhoid, Appendicitis, Tuberculosis, Trauma, Malignancy and non-specific infection.In Gastric perforations, Peptic ulcer was the most common cause of perforation followed by Trauma. In Ileal perforations, Typhoid was the most common cause of perforation followed by Tuberculosis and non-specific infection. In Appendicular perforations, most common cause was Appendicitis. In Jejunal perforations, most common cause was Trauma. In Colonic perforations, most common cause was Malignancy.Conclusions:The incidence of gastrointestinal perforations was common in 21-40 years age group followed by 41-60 years age group with male preponderance in our study. The most common site of perforations was Gastro-duodenal followed by Ileal perforations and the most common cause for these perforations was peptic ulcer followed by typhoid. The most common procedure done to treat gastrointestinal perforations was primary closure, resection and anastomosis, appendectomy and stoma formation. However, small sample size and short follow up period were the limitations of the present study.

Purpose: The objective of this study is to report a case of a primary aortoenteric fistula successfully treated with endovascular repair without aortic explant. Case Report: A 48-year-old man presented with a 24-hour history of hematemesis and malena. A computed tomography (CT) abdomen and pelvis demonstrated a 6 cm infrarenal aortic aneurysm with periaortic stranding and contrast enhancement within the lumen of the third part of the duodenum. The patient underwent emergency Endovascular Aortic Repair (EVAR). The patient was discharged on day 8 of his admission on oral antibiotics. He returned 7 weeks postindex procedure and underwent a laparotomy with omental patch repair of the aortic defect. Intraoperative cultures grew candida albicans, and the patient was discharged on lifelong oral Fluconazole and Amoxycillin-Clavulanic Acid. At 18 months postoperatively, the patient was clinically stable with improved appearances on CT aortogram. Conclusion: We discuss the use of EVAR without aortic explant as a possible treatment option in the management of patient with primary aortoenteric fistulae. This may potentially avoid the significant morbidity and mortality associated with aortic explant in suitable candidates without perioperative signs of sepsis.

In this paper, considering different parameters and various patch materials, the effect of disbond on the efficiency and durability of a composite patch repair is investigated in mode I and mixed-mode. One of the most important aspects of the composite patch repair is the bond strength. Repair patch disbond may occur at the patch edges or the crack site. At first, the effect of different parameters such as repair patch material and Young’s modulus and thickness of the adhesive on the efficiency and durability of the patch is investigated. Then, the effect of the disbond site on the stress intensity factor (patch efficiency) and adhesive stress (patch durability) is analyzed in both modes I and II. The results show that disbond at the crack site leads to a further reduction in patch efficiency compared to the patch edge disbond, but when separation occurs at the patch edge, the adhesive stress and the disbond growth rate are higher. Also, when 15% of the patch is separated in the crack site, for the longitudinal and transverse disbond modes, the mean KI is increased by 8 and 4%, respectively, compared to the state without disbond. Thus, the longitudinal disbond mode is more critical.

Background Endovascular treatment (EVT) using the common femoral artery (CFA) for access after endarterectomy (EA) may result in sheath insertion difficulties because of subcutaneous scar tissue, as well as difficulties with hemostasis. We evaluated the safety of CFA access and the ease of sheath insertion over time after EA. Method We included 19 patients (21 limbs, 40 cases) in whom the CFA was used after EA with autologous repair as an access route in EVT for peripheral arterial disease in our institution from January 2013 to December 2020. Nine limbs underwent simple closure repair and 12 underwent autologous patch repair. Difficult sheath insertions were defined as those in which additional devices (stiff guidewire or a smaller diameter sheath for dilation) were used for scheduled sheath insertion. The inability to insert a sheath with the scheduled diameter was defined as a failed sheath insertion. We evaluated the EVT timing after EA for difficult sheath insertions, and whether the CFA was repaired with simple closure or autologous patch repair during EA surgery. Results There were 10 (25%) difficult sheath insertions, with one (2.5%) failure. The rate of difficult sheath insertions peaked from 6 months to 1 year after EA and gradually decreased (47% from 6 months to 3 years, 14% thereafter). There were more statistically significant difficult sheath insertions with simple closure repair (50%) than with autologous patch repair (12%) (P = 0.018). Hemostasis devices were used in 90% of EVT cases. The median maximum sheath diameter was 6 Fr (mean = 5.8 Fr). None of the cases required surgical procedures to achieve hemostasis after EVT. Conclusion EVT may be performed safely using the CFA after EA. The difficulty of sheath insertion may differ depending on the EVT timing after EA; it was more difficult with simple closure than with autologous patch repair, possibly related to scar formation.

In this report, we present a case study of an extremely rare left sinus Valsalva aneurysm (SVA) rupture into the left-ventricular myocardium. Acute ozone inhalation and long-term hypertension are possible contributors to the condition. Utilizing multimodal cardiovascular imaging techniques [echocardiogram, computed tomography (CT), and cardiac magnetic resonance (CMR)], a large, left-ventricular, intramural pseudoaneurysm (IPA) arising from the ruptured left SVA, was clearly observed anatomically and functionally. Subsequently, our patient underwent patch repair and valvoplasty which offered an excellent prognosis. This report describes the manifestation of the ruptured left SVA and its possible etiology. This case also emphasizes the need for multimodal imaging for subsequent surgical repair.

Abstract As one of cost-effective maintenance methods, bonded composite patch repair has been receiving more and more attention in the engineering community since past decades. However, realizing real-time monitoring for curing process of bonded repair patch is difficult for most current techniques. In our work, a method based on electromechanical impedance and system parameters evaluation for structural health monitoring issues was developed, which could implement the online monitoring throughout whole curing process. Compared with the dynamic thermomechanical analysis results, the experiment data matches well. It demonstrates that the proposed approach can effectively monitor the curing process of composite repair patch at a constant temperature of 120 °C. Hence, the presented approach in this paper is expected to be a novel, robust, and real-time monitoring method for structural maintenance with the composite patch.

Abstract Objectives Patients with repaired complete atrioventricular septal defect (CAVSD) represent an increasing portion of grown-ups with congenital heart disease. For repair of CAVSD, the single-patch technique has been employed first. This technique requires division of the bridging leaflets, thus, among other issues, long-term function of the atrioventricular valves is of particular concern. Methods Between 1978 and 2001, 100 consecutive patients with isolated CAVSD underwent single-patch repair in our institution. Hospital mortality was 11%. Primary endpoints were clinical status, atrioventricular valve function, and freedom from reoperation in long term. Follow-up was obtained contacting the patient and/or caregiver, and the referring cardiologist. Results Eighty-three patients were eligible for long-term follow-up (21.0 ± 8.7, mean ± standard deviation [21.5; 2.1–40.0, median; min–max] years after surgical repair). Actual long-term mortality was 3.4%. Quality of life (QoL; self- or caregiver-reported in patients with Down syndrome) was excellent or good in 81%, mild congestive heart failure was present in 16%, moderate in 3.6% as estimated by New York Heart Association classification. Echocardiography revealed normal systolic left ventricular function in all cases. Regurgitation of the right atrioventricular valve was mild in 48%, mild–moderate in 3.6%, and moderate in 1.2%. The left atrioventricular valve was mildly stenotic in 15% and mild to moderately stenotic in 2%; regurgitation was mild in 54%, mild to moderate in 13%, and moderate in 15% of patients. Freedom from left atrioventricular-valve-related reoperation was 95.3, 92.7, and 89.3% after 5, 10, and 30 years, respectively. Permanent pacemaker therapy, as an immediate result of CAVSD repair (n = 7) or as a result of late-onset sick sinus syndrome (n = 5), required up to six reoperations in single patients. Freedom from pacemaker-related reoperation was 91.4, 84.4, and 51.5% after 5, 10, and 30 years, respectively. Conclusion Up to 40 years after single-patch repair of CAVSD, clinical status and functional results are promising, particularly, in terms of atrioventricular valve function. Permanent pacemaker therapy results in a life-long need for surgical reinterventions.

Ventricular diverticulum is a rare congenital malformation. Although most patients are asymptomatic, it can present with rupture and sudden death, for which surgical repair is indicated. The authors report the case of a 5-year-old boy with a prenatal diagnosis of an isolated left ventricular diverticulum. It was decided for surgical closure; however, a persisting leakage at the patch repair site was observed, for which a transcatheter percutaneous closure approach was used, achieving complete occlusion of the defect. Transcatheter closure of suitable ventricular diverticula is a safe and effective option.
