INTRODUCTION:  Sutureless biological valves for surgical aortic valve replacement (SAVR), characterized by the absence of anchoring sutures at the aortic annulus, are gaining popularity because of ease and reproducibility of implant, shorter operating times, and enhancement of minimally invasive approaches. The stentless configuration of the sutureless valve was designed to achieve optimal hemodynamic performance. MATERIALS AND METHODS:  PERSIST-AVR (PERceval Sutureless Implant versus STandard Aortic Valve Replacement) is a prospective, randomized, adaptive, open-label, international, postmarket trial (NCT02673697)...

OBJECTIVES: Structural valve deterioration (SVD) remains a major bioprosthesis-related complication, as recently described for the Mitroflow valve (models LX and 12A) (LivaNova, London, United Kingdom). The real incidence of the SVD risk remains unclear, often due to methodologic pitfalls by systematically using the Kaplan-Meier estimator and/or the Cox model. In this report, we propose for the first time a precise statistical modeling of this issue. METHODS: Five hundred sixty-one patients who underwent aortic valve replacement with the aortic Mitroflow valve between 2002 and 2007 were included...

Transcatheter aortic valve replacement (TAVR) is not currently approved for pure native valve aortic incompetence, and is typically performed on a compassionate basis in selected patients who are at high risk for conventional surgery. We describe the first use of TAVR to treat iatrogenic severe acute pure aortic incompetence following mitral valve surgery. A 71-year-old gentleman developed life-threatening acute aortic regurgitation (AR) within hours of a very challenging fifth open heart mitral valve replacement...

Congenital heart disease (CHD) affects a considerable number of children and adults worldwide. This implicates not only developmental disorders, high mortality, and reduced quality of life but also, high costs for the healthcare systems. CHD refers to a variety of heart and vascular malformations which could be very challenging to reconstruct the malformed region surgically, especially when the patient is an infant or a child. Advanced technology and research have offered a better mechanistic insight on the impact of CHD in the heart and vascular system of infants, children, and adults and identified potential therapeutic solutions...

We present a clinical case of successful correction of aneurismatic dilatation of the anastomosis zone after allotransplant implantation. In 2004 this patient underwent implantation of an arterial allotransplant of "complex architectonics" because of trauma of the iliofemoral arterial segment. After 12 years he reported appearance of discomfort in the left side of the abdomen. Duplex ultrasound scanning revealed aneurism at the site of anastomosis of the prosthesis with internal iliac artery. Therefore, we performed endovascular isolation of the aneurism with the use of a stent-graft and restoration of blood flow down to the extremity periphery has been performed...

A 24-year-old man with dilated aortic root and vascular type Ehlers-Danlos Syndrome underwent aortic root replacement with a stentless bioprosthesis. A year later he developed aortic valve endocarditis necessitating a redo valve replacement. Excised valve tissue grew fungus Purpureocillium lilacinum. Over a period of four years case was further complicated with mycotic aneurysm of the infra-renal aorta, a retroperitoneal abscess (treated surgically), a right common iliac aneurysm, right lower limb emboli (femoral embolectomy and left -to-right femoral bypass was performed), two false aneurysms of the ascending aorta with a large mobile mass attached to the anterior aneurysm and brain abscesses...

BACKGROUND: The incidence of structural valve deterioration after bioprosthesis (BP) aortic valve replacement (AVR) established on the basis of reoperation may substantially underestimate the true incidence. The objective is to determine the rate, timing, correlates, and association between hemodynamic valve deterioration (HVD) and outcomes assessed by Doppler echocardiography after surgical BP AVR. METHODS: A total of 1387 patients (62.2% male, 70.5±7.8 years of age) who underwent BP AVR were included in this retrospective study...

Primary mediastinal tumours with chest wall involvement represent technical challenges that may offer a survival benefit. Reconstruction with osteossynthesis material, bioprosthesis and muscle flaps is indicated to re-establish the excised component function. We report a case of a 30-year-old male with a primary mediastinal seminoma operated after chemotherapy with need for en bloc resection of the residual mass and manubrium with chest wall reconstruction. This type of surgery is rare and represents a technical challenge...

Over the last decade, aortic valve replacement with rapid-deployment biological bioprosthesis has become a common alternative technique to mechanical or biological stented valves for high-risk patients. A 63 year old patient underwent uncomplicated valve replacement with the Edwards Intuity valve. 2 months post operation, the patient had progredient dyspnea. Echocardiography showed a dislocated aortic valve reaching into the left ventricular outflow tract, impairing the anterior mitral valve leaflet. Both valves were replaced by a conventional stented bioprosthesis...
