INTRODUCTION: Vascular homografts are used for limb salvage in cases of graft infection after previous reconstructive vascular surgery or inadequate autologous veins. During multi-organ donation the thoracic aorta segment, aortic bifurcation, iliac arteries, femoral arteries, popliteal arteries, femoral veins and greater saphenous veins can be harvested. Our aim was to optimize the use of homografts by analyzing the results of previous procedures. METHODS: The patient information was processed retrospectively, using the clinical computer system...

INTRODUCTION: The middle ear ossicles form a semi rigid chain in the middle of the ear for conduction and amplification of sound waves from the tympanic membrane to the inner ear. Although, our knowledge of the ear ossicles dates back to the 15(th) century, and various studies have been carried out on their morphometry, morphology, anomalies, embryology, function and structure throughout the world, information about the morphology of middle ear ossicles is meagre in Indian subjects. AIM: To find out the morphological variations of middle ear ossicles of right and left sides...

BACKGROUND: The polytetrafluoroethylene tube used as right ventricle to pulmonary artery conduit in the stage 1 Norwood operation is associated with risks of suboptimal branch pulmonary artery growth, thrombosis, free insufficiency, and long-term right ventricular dysfunction. Our experience with use of valved femoral vein homograft as right ventricle to pulmonary artery conduit is described. METHODS: Between June 2012 and December 2015, 15 neonates with hypoplastic left heart syndrome or complex single ventricle underwent stage 1 Norwood operation with valved segment of femoral vein homograft as right ventricle to pulmonary artery conduit...

OBJECTIVES: Coexisting aortic root and mitral valve pathology is increasingly recognized among patients undergoing surgery. We characterized the pathology and surgical outcomes of patients with combined aortic root and mitral disease. METHODS: From 1987 to 2016, 118 patients (age 52.40 ± 17.71 years) underwent concomitant aortic root and mitral procedures (excluding aortic stenosis, endocarditis, and reoperations). Aortic root pathologies included degenerative aneurysm (94%) and aortic dissection (6%)...

INTRODUCTION: Neisseria macacae is a Gram-negative diplococcus, found in the oropharynx of healthy Rhesus Monkeys. Infections caused by N. macacae in humans are extremely rare. CASE PRESENTATION: We present here the first case of N. macacae infective endocarditis in a 65-year-old man with a native aortic valve infection complicated by a peri-aortic abscess. N. macacae was isolated from blood culture and was found on the cardiac valve using 16S rDNA detection. Despite an appropriate antibiotic therapy, and aortic homograft replacement, and mitral repair, the patient died 4 days after surgery from a massive hemorrhagic stroke...

BACKGROUND: In the patients with longer-segment aortic arch hypoplasia or interruption with ventricular septal defect, surgery with homograft vessel or autologous pericardial patch to augment descending aortic arch will not result in adverse reactions caused by end-to-end anastomosis. In this study, we retrospectively analyzed primary experience of surgical correction of complicated aortic arch anomaly with autologous main pulmonary artery. METHODS: From July 2010 to March 2016, the twenty-one cases of aortic arch complex anomalies were reconstructed with autologous main pulmonary artery...

BACKGROUND: The Ross procedure is used in the treatment of selected patients with aortic valve disease. Pulmonary graft stenosis can appear in the long-term follow-up after the Ross intervention, but the factors involved and its clinical implications are not fully known. AIM: To describe the incidence, clinical impact and predictors of homograft stenosis and reintervention after the Ross procedure in a prospective series in a tertiary referral hospital. METHODS: From 1997 to 2009, 107 patients underwent the Ross procedure (mean age: 30±11 years; 69% men; 21 aged<18 years), and were followed for echocardiographic homograft stenosis (peak gradient>36mmHg) and surgical or percutaneous homograft reintervention...

Peripheral pulmonary artery stenosis (PPAS) is a rare form of congenital heart disease that is most frequently associated with Williams and Alagille syndromes. These patients typically have systemic level right ventricular pressures secondary to obstruction at the lobar, segmental, and subsegmental branches. The current management of patients with PPAS remains somewhat controversial. We have pioneered an entirely surgical approach for the reconstruction of PPAS. This approach initially entailed a surgical patch augmentation of all major lobar branches and effectively reduced the right ventricular pressures by more than half...

BACKGROUND: Surgical repair of common arterial trunk (CAT) by means of a homograft conduit has become a standard practice. We report our experience in the correction of this heart disease with a handmade bovine pericardial-valved woven Dacron conduit as an alternative procedure to homografts, with a focus on early, mid-term, and long-term results. METHODS: We designed a retrospective study that included 15 patients with a mean age of 1.5 years (range: three months to eight years), who underwent primary repair of simple CAT...

BACKGROUND: The development of recoarctation after the Norwood I procedure is a known complication in patients with hypoplastic left heart syndrome (HLHS). METHODS: We reviewed data on 194 consecutive patients with HLHS who underwent the Norwood I procedure between 2000 and 2015. All patients who survived until the second stage of the procedure were included. Recoarctation was defined by the need for intervention, either catheter based or surgical. The aim of our study was to determine if the patch material used for the initial arch reconstruction had an influence on the development of recoarctation...

BACKGROUND: The management of graft infection following ascending aortic replacement (AAR) and/or aortic valve replacement (AVR) with destruction of the root remains a challenge. Besides technical issues, the choice of graft material is controversial. The study aim was to investigate the initial results of aortic root replacement (ARR) as redo-surgery for infection using the xenopericardial all-biologic conduit (BioIntegral) as an alternative to a homograft or prosthetic material. METHODS: Between February 2013 and January 2015, a total of 18 consecutive patients (16 males, two females; mean age 61 ± 14 years) were reoperated on for infection at a mean of 55 ± 61 months (range: 3 to 219 months) following previous AVR (n = 6), supracoronary aortic replacement (SAR, n = 2), AVR + SAR (n = 1), root replacement (n = 7), and root reconstruction (n = 2)...

Aortic root reconstruction in the setting of redo aortic valve procedures or infective endocarditis may be technically challenging, particularly because of variable destruction or distortion of the left ventricular outflow tract. Homograft aortic root replacement is an excellent option for aortic root abscesses but is limited by homograft availability. We describe a simple technique of a bioprosthetic valved conduit constructed on the table using a Dacron (DuPont, Wilmington, DE) skirt below the valve. The use of the Dacron skirt facilitates easy reconstruction of the left ventricular outflow tract...

Pulmonary artery dissection was diagnosed in a 32-year-old man who was admitted to the emergency department with intense chest pain. He had a history of pulmonary balloon valvuloplasty for congenital pulmonary stenosis at the age of 7 and no pulmonary hypertension. The operation was performed with cardiopulmonary bypass. The dissected pulmonary arterial trunk was removed with the distorted valve, and replaced with a pulmonary artery homograft. The postoperative course was uneventful. Histologic examination revealed medionecrosis...

BACKGROUND: The limited treatment option for recurrent prostate cancer and eventual resistant to conventional chemotherapy drugs has fueled continued interest in finding new anti-neoplastic agents. WZ35, a chemical analog of curcumin, had been demonstrated to have high chemical stability and potential anticancer effects in gastric cancer cells. The present study aimed to investigate the anti-prostate cancer effects of WZ35 in vitro and in vivo as well as the underlying mechanism. METHODS: Two prostate cancer cell lines RM-1 and DU145 were utilized to test the anti-cancer effects of WZ35 and the underlying mechanism...

Reoperations after the Ross procedure are rare, with autograft as well as homograft failure being the dominant causes for redo cardiac procedures. Due to increasing experience with valve-sparing aortic valve procedures, more valves can be preserved during redo surgery. Herein are reported the details of a patient who underwent quadruple valve reoperation comprising redo with a reconstructive approach after the short-term failure of pulmonary autograft and homograft with concomitant mitral and tricuspid regurgitation...
