A 52-year-old woman was admitted to our hospital for acute right hemi-paresis, left homonymous hemianopia, and fever. Magnetic resonance imaging of the brain showed multiple cerebral infarctions and transesophageal echocardiography (TEE) revealed a vegetation on the posterior leaflet of her mitral valve. Mitral valve repair was performed under a diagnosis of infective endocarditis (IE). Further multiple cerebral infarctions occurred on the 11th postoperative day, resulting in left hemiplegia and dysarthria...

BACKGROUND: Aortic valve insufficiency (AI) at the time of left ventricular assist device (LVAD) insertion needs to be corrected, however there is little known about how to manage bioprosthetic valvular AI. CASE PRESENTATION: A 55-year-old female with dilated cardiomyopathy who previously had a bioprosthetic aortic valve replacement needed a LVAD as a bridge to transplant. Her left ventricular ejection fraction was 10% and had mild to moderate transvalvular AI. She underwent a HeartWare HVAD insertion along with aortic valvular coaptation stitch repair (Park's stitch) to the bioprosthetic valve...

OBJECTIVE: To describe a total endovascular aortic repair with branched and fenestrated endografts in a young patient with Marfan syndrome and a chronic aortic dissection. Open surgery is the gold standard to treat aortic dissections in patients with aortic disease and Marfan syndrome. METHODS: In 2000, a 38-year-old man with Marfan syndrome underwent open ascending aorta repair for an acute type A aortic dissection. One year later, a redo sternotomy was performed for aortic valve replacement...

BACKGROUND: Endovascular aortic aneurysm repair (EVAR) and transfemoral transcatheter aortic valve replacement (TAVR) are widely spreading minimally invasive procedures performed mainly through the femoral artery. Prostar XL and ProGlide vascular closure devices are used in clinical practice for the hemostasis in these procedures and they have been shown to be safe and effective. PURPOSE: The aim of our systematic review is to compare the safety of these two devices for percutaneous closure of large arteriotomies in patients undergoing TAVR and EVAR...

BACKGROUND AND AIM: Aortic valve (AV) prolapse and subsequent aortic regurgitation (AR) are two complications of ventricular septal defects (VSD) that are located close to or in direct contact with the AV. This finding is one of the indications for surgical VSD closure even in the absence of symptoms to protect the AV integrity. The goal of our study was to assess the outcome and to identify the predictors for improvement or progression of AR after surgical repair. MATERIALS AND METHODS: A retrospective study of all children with VSD and AV prolapse who underwent cardiac surgery at King Abdulaziz Cardiac Centre in Riyadh between July 1999 and August 2013...

OBJECTIVE: Long-term sequelae and events after coarctation repair are well described. However, the predictive value of variables from clinical follow-up investigation for late events and survival has rarely been investigated. METHODS: All patients who participated in the prospective cross-sectional COALA Study in 2000 with a structural clinical investigation including blood pressure measurement and symptom-limited exercise test were contacted for reevaluation of survival, current clinical status and major cardiovascular events...

Aortic root aneurysms associated with severe pectus excavatum caused by Marfan's syndrome can be challenging to correct in children. Recent reports suggest single-stage correction of both cardiac and chest wall deformities through a median sternotomy. We report a 9-year-old girl with Marfan's syndrome, an ascending aorta aneurysm, mitral regurgitation, and pectus excavatum, who underwent David's procedure with mitral valve repair and the Nuss procedure to correct the thoracic deformity. This single-stage combined procedure was performed through a left anterolateral thoracotomy...

A 79-years-old woman was diagnosed with severe aortic stenosis and referred to our institution for the purpose of an operation. We decided to perform transfemoral transcatheter aortic valve implantation because of her high frailty due to her age and medication of long-term steroid for chronic rheumatoid arthritis. In the operation, left ventricular perforation occurred by the guide wire and cardiac tamponade was detected. We performed pericardial drainage and controlled bleeding through the 5th intercostal thoracotomy and trasncatheter aortic valve implantation was performed after that...

A 45-year-old male with a prosthetic aortic valve presented to the hospital with several months of generalized malaise. On admission, he was noted to have anemia of unclear etiology and subsequently became febrile with multiple blood cultures growing Lactococcus garvieae. Inpatient workup was concerning for infectious endocarditis (IE) secondary to Lactococcus. The patient was discharged home with appropriate antimicrobial therapy; however, he was readmitted for persistent, symptomatic anemia and underwent colonoscopy, which revealed innumerable colonic polyps consistent with Familial Adenomatous Polyposis (FAP) that was later confirmed with genetic testing...

BACKGROUND: Patients undergoing hybrid aortic arch reconstruction require careful protection of vital organs. We believe that whole body perfusion with tailored dual circuitry may help to achieve optimal patient outcomes. METHODS: Our circuit has evolved from a secondary circuit utilizing a cardioplegia delivery device for lower body perfusion to a dual-oxygenator circuit. This allows individually controlled regional perfusion with ease of switching from secondary to primary circuit for total body flow...

OBJECTIVES: A thorough understanding of mitral and aortic valve motion dynamics is essential in mastering the skills necessary for performing successful valve intervention (open or transcatheter repair or replacement). We describe a reproducible and versatile beating-heart mitral and aortic valve assessment and valve intervention training model in human cadavers. METHODS: The model is constructed by bilateral ligation of the pulmonary veins, ligation of the supra-aortic arteries, creating a shunt between the descending thoracic aorta and the left atrial appendage with a vascular prosthesis, anastomizing a vascular prosthesis to the apex and positioning an intra-aortic balloon pump (IABP) in the vascular prosthesis, cross-clamping the descending thoracic aorta, and finally placing a fluid line in the shunt prosthesis...

OBJECTIVE: The need for biological markers of aortic wall stress and risk of rupture or dissection of ascending aortic aneurysms is obvious. To date, wall stress cannot be related to a certain biological marker. We analyzed aortic tissue and serum for the presence of different MMP-2 isoforms to find a connection between serum and tissue MMP-2 and to evaluate the potential of different MMP-2 isoforms as markers of high wall stress. METHODS: Serum and aortic tissue from n = 24 patients and serum from n = 19 healthy controls was analyzed by ELISA and gelatin zymography...

BACKGROUND: Stent grafting is a therapeutic option for patients who are unable to undergo urgent surgical repair of ascending aortic dissections. However, follow-up regarding outcomes is limited. OBJECTIVES: This study reports mid-term outcomes with endovascular repair for ascending aortic dissections in patients deemed high risk for open repair. METHODS: Between May 1, 2009 and January 31, 2011, 15 ascending aortic dissection patients (ages 45 to 78 years) ineligible for direct surgical repair underwent endovascular repair (1 acute dissection, 7 subacute dissections, and 7 chronic dissections) and were closely followed up for a median of 72 months (range 61 to 81 months)...
