OBJECTIVES: We investigated the hypothesis that early surgery for infective endocarditis (IE) attenuates the rate of death or embolic events and does not increase the rate of relapse or postoperative valvular dysfunction (PVD) at 6 months. METHODS: 21 consecutive patients who underwent surgical treatment of IE were prospectively included. We assessed 6-month postoperative clinical outcomes by comparing early surgery (Group E, surgery within 72 h) and conventional treatment (Group C)...

BACKGROUND: Partial anomalous pulmonary venous return is a rare congenital cardiac anomaly that usually involves the right pulmonary vein and an atrial septal defect. Isolated partial anomalous pulmonary venous return with an intact atrial septum is even rarer, and this condition is usually treated surgically in younger patients. We describe isolated partial anomalous pulmonary venous return in a 65-year-old woman who was treated by caval division with pericardial patch baffling through a surgically created atrial septal defect and reconstruction of the superior vena cava using a prosthetic graft...

This study aimed to evaluate the safety and effectiveness of an alternative dural substitute using a porcine pericardial graft for duraplasty in a large animal model. Six pigs underwent bilateral craniectomy followed by bilateral duraplasty using either a porcine pericardium patch or a Biodesign® Dural Repair Graft. Intraoperative workability was evaluated for each type of graft. Pigs were euthanized after 1 and 3 months (n = 3 per group). Histological analysis was performed for each case. The Biodesign® Dural Repair Graft showed better workability than the porcine pericardial patch, which was more transparent (p = 0...

Pericardial scaffolds have a wide spectrum of clinical applications ranging from patches for vascular reconstruction and abdominal wall defects to bioprosthetic heart valves. The current gold standard of tissue preparation involves disinfection and crosslinking using glutaraldehyde. However, glutaraldehyde-associated toxicity as well as rapid calcification and premature graft failure represent the major modes of failure <sup>1</sup>. Therefore, a variety of alternative strategies for tissue conservation have been pursued...

Repair of ventricular septal rupture post acute myocardial infarction remains a surgical challenge. Several techniques for the closure of these defects have been described. We modified the infarct exclusion technique as described by Tirone David. In this technique two separate pericardial patches are used. The first patch excludes the rupture. The second patch is sutured to the margins of the first patch which provides strength to the margins of the first patch. It is simple, durable and has reduced incidence of residual ventricular septal defects and patch dehiscence...

Pericardial tissue is widely used as a biomaterial, especially for cardiovascular application. Tissue processing plays a key role in developing future scaffolds derived from biological material, yet standardized evaluation is still pending. This study presents a comprehensive assessment of different treatment protocols of bovine pericardium and compares those findings to commercially available decellularized bovine (CAB) and equine (CAE) pericardial patches. Native samples were fixed with glutaraldehyde (GA) or decellularized...

Left atrial appendage occlusion (LAAO) devices offer stroke prevention in atrial fibrillation for patients intolerant of anticoagulation. Device placement leading to bleeding and cardiac tamponade have been reported periprocedurally but delayed presentations have not been reported in the literature. We present the case of an Amulet LAAO device causing erosion and bleeding from the main pulmonary artery that presented with cardiac tamponade 6 months after device placement. The pulmonary artery defect was repaired primarily and buttressed with a pericardial patch with good result...

Ventricular septal defect (VSD) is a life-threatening complication of myocardial infarction. Surgical repair is generally performed through a left/right ventriculotomy. To avoid complications associated with ventriculotomy, a right transatrial approach has been proposed. We describe a modified transatrial approach through the left atrium for basal-inferior VSD. After left atriotomy, mitral valve is detached from the annulus to expose the defect, which is closed with a pericardial patch. Two patients were operated by this method...

Decellularized biological scaffolds hold great promise in cardiovascular surgery. In order to ensure off-the-shelf availability, routine use of decellularized scaffolds requires tissue banking. In this study, the suitability of cryopreservation, vitrification and freeze-drying for the preservation of decellularized bovine pericardial (DBP) scaffolds was evaluated. Cryopreservation was conducted using 10% DMSO and slow-rate freezing. Vitrification was performed using vitrification solution (VS83) and rapid cooling...

OBJECTIVE: Although seen rarely compared to all tumors, cardiac tumors are tumors which may have a mortal course with possible complications. The most common cardiac tumor in adults is myxoma with its benign character. The results of cardiac tumors resected with open cardiac surgery in our center are reported in this study. MATERIALS AND METHODS: Twenty-three cardiac tumor patients electively operated on in our clinic between January 2010 and August 2017 were retrospectively included in the study...

BACKGROUND: Rheumatic heart disease (RHD) is the leading cause of mitral valve disease in the developing world. In general, mitral valve repair is preferred over replacement. Although it is very successful in degenerative disease, its results in the rheumatic valve are not as successful as that for degenerative repair. Our approach has been to repair rheumatic mitral valves when the anatomic substrate appears to permit it, and we aimed by this study to present our immediate and midterm follow-ups of our cohort of rheumatic valve repair patients...

A 77-year-old man was admitted to a regional hospital to undergo investigation of abnormal electrocardiographic findings. Coronary angiography revealed 99% stenosis of the right coronary artery(RCA) segment 3 and 75% stenosis of the left anterior descending artery (LAD)segment 7. Left ventriculography revealed an aneurysm at the inferior wall of the left ventricle. On computed tomography and echocardiography, a saccular aneurysm at the inferior wall, 15 mm in diameter, was observed. Under the suspicion of a ventricular false aneurysm resulting from myocardial infarction, aneurysmectomy, patch closure of the aneurysmal orifice and coronary artery bypass grafting to the LAD and RCA were performed...

Infective endocarditis (IE) after transcatheter aortic valve replacement (TAVR) is a rare complication, but has a high mortality. An 86-year-old female with symptomatic severe aortic stenosis underwent TAVR at our hospital and she was discharged without complication after 10 days. She was readmitted with high fever and acute heart failure 1 month later. Blood culture revealed Staphylococcus, and echocardiography showed vegetation on the septal cusp of the tricuspid valve and perforation at the membranous ventricular septum...

Introduction: Patients with undiagnosed anterior mediastinal tumors commonly undergo surgery for diagnosis and treatment. However, determining the optimal therapeutic strategy is difficult for tumors with substantial invasion, such as lesions touching the aortic arch (AA). Case presentation: A 76-year-old man of Asian descent presented to our hospital because chest computed tomography (CT) revealed an anterior mediastinal tumor. This tumor surrounded the left subclavian vein and touched the AA...

A 34-year-old gentleman, who had undergone pericardial patch closure of ostium secundum atrial septal defect (ASD) at 8 years of age, was evaluated for shortness of breath. Electrocardiogram revealed typical atrial flutter with varying atrioventricular conduction. Echocardiogram showed no residual ASD or pulmonary hypertension and good biventricular function. He was taken for an electrophysiological study with the intention of radiofrequency ablation of the typical flutter.

Anomalous origin of the right coronary artery (RCA) from the pulmonary artery is a rare entity that causes chronic left-to-right shunting of blood from the RCA, through the coronary collaterals into the pulmonary artery. This results in persistent myocardial ischemia and ventricular dysfunction. Association of this anomaly with an aortopulmonary window worsens the condition further due to an additional shunt. We encountered a combination of these two anomalies along with an ostium secundum atrial septal defect in a 10-month-old baby who presented with excessive crying and failure to thrive...

A major limitation of the more widespread application of aortic valve reconstruction is the lack of a common framework for valve assessment that could  be used to guide a standardized approach to aortic valve repair, similar to that used in reconstructive mitral valve surgery. Most patients with a regurgitant aortic valve are young and possess a specific subtype of a bicuspid aortic valve according to the Sievers classifications system. This video tutorial presents the technical aspects of a standardized approach for reconstruction of the regurgitant bicuspid aortic valve (Sievers type 1, L/R), which was developed during the past decade...

Aortic valvuloplasty (AVP) has been performed less frequently than mitral valvuloplasty. The survival benefit of AVP over replacement has been demonstrated. Therefore, standardization of AVP is crucial for its widespread adoption. The hemodynamic advantage of AVP of preserving the native aortic valve may be one reason for the survival benefit. Recent guidelines still recommend AVP in selected cases compared with the less restricted recommendation for mitral valvuloplasty, although recent studies have proposed earlier indication for surgical intervention...

Implant associated granulomatous inflammation causing hypercalcemia can occur following use of commercial xenogeneic pericardial tissue patches in dogs. Removal of the implant can result in resolution of the hypercalcemia, suggesting a causal relationship between the tissue reaction to a xenogeneic implant and development of hypercalcemia.
