Infective endocarditis is a rare disease associated with high morbidity and mortality. As a result, early diagnosis and prompt antibiotic treatment with or without surgical intervention is crucial in the management of such condition.We report a case of missed infective endocarditis of the aortic valve. The patient underwent mechanical aortic valve replacement, with the native valve being sent for histopathological examination. On re-admission 16 months later, he presented with syncope, shortness of breathing and complete heart block...

AIMS: Transcatheter aortic valve implantation for a failing surgical bioprosthesis (TAV- in-SAV) has become an alternative for patients at high risk for redo surgical aortic valve replacement (redo-SAVR). Comparisons between these approaches are non-existent. This study aims to compare clinical and echocardiographic outcomes of patients undergoing TAV-in-SAV versus redo-SAVR after accounting for baseline differences by propensity score matching. METHODS AND RESULTS: Patients from 7 centres in Europe and Canada who had undergone either TAV- in-SAV (n=79) or redo-SAVR (n=126) were identified...

We present a case of transcatheter valve-in-valve replacement performed because of structural valve deterioration of a subcoronary implanted stentless aortic bioprosthesis. A 23-mm self-expandable transcatheter heart valve (THV) with supraannular seating was chosen. The procedure was performed with the patient under conscious sedation. After anchoring and partial valve deployment, the patient experienced an acute onset of angina. The angiogram showed left main coronary artery obstruction. Prompt resheathing and retrieval of the THV was performed, and the procedure was aborted...

PATIENT PRESENTATION: We report the case of a 66 year old female who presented to our institution fourteen years after receiving a St. Jude Mechanical Mitral Valve Replacement. She presented in refractory NYHA class IV congestive heart failure with comorbidities of acute renal failure, liver failure, and mental status changes. She was found to have immobility of one of the mitral valve disks with resultant severe mitral stenosis with a mean pressure gradient of 12 mmHg. EVALUATION AND MANAGEMENT: The patient was found to have an STS predicted mortality of 39% with redo surgical MVR, and evaluation by the valve team led to a recommendation of a hybrid surgical and transcatheter procedure...

BACKGROUND: With improved survival of patients undergoing primary bioprosthetic aortic valve replacement (AVR), reoperation to relieve severe prosthetic aortic stenosis (PAS) is increasing. Timing of redo surgery in asymptomatic/minimally symptomatic patients remains controversial. Left ventricular (LV) global longitudinal strain (GLS) is a marker of subclinical LV dysfunction. In asymptomatic/minimally symptomatic patients with severe PAS undergoing redo AVR, we sought to determine whether LV-GLS provides incremental prognostic use...

The case is reported of a 79-year-old female who received a patch augmentation of the tricuspid anterior and septal leaflets with a resected left atrial wall to address recurrent tricuspid regurgitation, including tricuspid valve tethering. The patient was admitted to the authors' hospital for chronic heart failure with paravalvular leakage after aortic valve replacement and recurrent severe tricuspid regurgitation. She had undergone two previous cardiac surgeries. Re-tricuspid repair required an augmentation of the tricuspid valve leaflets in addition to tricuspid annuloplasty...

Background Permanent pacemaker implantation after surgical aortic valve replacement depends on patient selection and risk factors for conduction disorders. We aimed to identify risk criteria and obtain a selected group comparable to patients assigned to transcatheter aortic valve implantation. Methods Isolated sutured aortic valve replacements in 994 patients treated from 2007 to 2015 were reviewed. Demographics, hospital stay, preexisting conduction disorders, surgical technique, and etiology in patients with and without permanent pacemaker implantation were compared...

INTRODUCTION: This retrospective study examined the role of aortic valve (AV) disease in patients who underwent orthotopic liver transplantation (OLT) to determine the incidence of postoperative cardiac morbidity and mortality when compared with a matched control group without AV disease. METHODS: Patients were included in the AV group if diagnosed with aortic stenosis (AS) or aortic regurgitation or had received AV replacement prior to OLT. The AV group (n = 53) was matched to a control group (n = 212) with the following preoperative variables: type of organ transplanted, age, gender, race, body mass index, MELD, redo-transplantation, preoperative renal replacement therapy, nonalcoholic steatohepatitis, viral hepatitis, diabetes, and coronary artery disease...

BACKGROUND: Hemolytic anemia caused by a kinked Dacron graft is a rare complication after repair of acute aortic dissection. We present a case of hemolytic anemia due to kinking of previously implanted Dacron graft for ascending aorta dissection treated by surgery and replaced with new Dacron. CASE DETAILS: We report a case of postoperative hemolytic anemia with kinking of the graft at the outer graft layer and intra luminal bulging of the inner graft. Postoperative computed tomography showed Dacron graft kinking at the mid part of the graft...

OBJECTIVE: Valve-in-valve procedures using transcatheter aortic valves are increasingly performed to treat degenerated bioprosthetic surgical aortic valves because they are less invasive than redo aortic valve replacement. The objective of this study is to quantify the changes in aortic sinus blood flow dynamics before and after a valve-in-valve procedure to gain insight into mechanisms for clinical and subclinical thrombosis of leaflets. METHODS: A detailed description of the sinus hemodynamics for valve-in-valve implantation was performed in vitro...

A 6-year-old girl with unbalanced atrioventricular septal defect, hypoplastic right ventricle, and severe common atrioventricular valve regurgitation developed patient-prosthetic mismatch. At 6 months old, she underwent primary one and one-half ventricle repair and replacement of left side atrioventricular valve. A catheter examination showed that her right ventricular end-diastolic volume increased from 39.4 mL/m(2) 1 year after to 70 mL/m(2) 3.5 years after the previous surgery. Thus, at the timing of redo left side atrioventricular valve replacement, she was converted successfully to biventricular circulation...

OBJECTIVES: Our goal was to report on early and midterm outcomes of hemiarch replacement performed in a high-volume centre. METHODS: We extrapolated hemiarch replacements from our institutional aortic database. We also analysed the impact of aortic disease (dissection vs aneurysm) on the outcomes of de novo hemiarch replacement. RESULTS: A total of 756 patients underwent hemiarch replacement between 1997 and 2016. After elimination of cases involving the aortic root/valve and redo cases, we identified 426 cases of de novo -isolated hemiarch replacement (369 aneurysms and 57 dissections)...

INTRODUCTION: Redo surgical aortic valve replacement after prior cardiac surgery is usually related to a higher risk of mortality and morbidity. Transcatheter aortic valve implantation (TAVI) became an alternative therapy for those patients in the past couple of years. EVIDENCE ACQUISITION: We aimed in this study to analyze the outcomes of patients undergoing TAVI after a prior cardiac surgery especially those who underwent coronary artery bypass grafting (CABG) and to see if TAVI offers any advantages for those patients than conventional surgical aortic valve replacement...

BACKGROUND: Loeys-Dietz syndrome (LDS) is an aggressive aortopathy with a proclivity for aortic aneurysm rupture and dissection at smaller diameters than other connective tissue disorders. We reviewed our surgical experience of children with LDS to validate our guidelines for prophylactic aortic root replacement (ARR). METHODS: We reviewed all children (younger than 18 years) with a diagnosis of LDS who underwent ARR at our institution. The primary endpoint was mortality, and secondary endpoints included complications and the need for further interventions...
