OBJECTIVES: Mitral periprosthetic leakage (PPL) is a serious complication following valve replacement. Conflicting outcomes of surgical treatment have been reported in the presence of multiple previous cardiac operations and associated co-pathological conditions. METHODS: Sixty-five symptomatic patients (37 women, mean age 64.8 years) underwent conventional operations at our hospital from 2006 to 2015. Mitral PPL was the leading surgical indication, although associated procedures were included...

PURPOSE OF REVIEW: With widespread adoption of transcatheter aortic valve replacement, there has been a change in the approach to management of valvular heart disease. New interest has taken hold in transcatheter therapies for valvular heart disease, as well as research into pathophysiology and progression of disease. Additionally, several key trials have further refined our understanding of surgical management of valvular heart disease. This review will elucidate recent clinical trial data leading to changes in practice...

We report the case of a 57-year-old female suffering from recurrent malignant undifferentiated pleomorphic sarcoma of the left atrium. Metastasis to the posterior mediastinum was detected upon first presentation. Incomplete resections were carried out twice before mitral valve replacement was finally performed. The tumor recurred 16 months later and was treated with radiation therapy, which has proved to be effective in bringing about tumor regression for 2 years, to date. The patient has survived for 7 years since the first surgery...

We present a rare case of mitral regurgitation with anterior mitral leaflet perforation associated with gelatin-resorcinol-formaldehyde (GRF) glue. We performed mitral valve replacement for anterior mitral leaflet perforation occurred 7 years after aortic valve replacement and abscess cavity repair using GRF glue. Long-term follow-up is needed for patients who have undergone surgeries using GRF glue or BioGlue (CryoLife, Inc, Kennesaw, GA) because of the possibility of late complications. In particular, when an eccentric mitral regurgitation is observed after aortic root surgery using GRF glue or BioGlue, anterior mitral leaflet perforation should be considered...

OBJECTIVES: This study sought to use a new catheter technique to split the anterior mitral valve leaflet (AML) and prevent iatrogenic left ventricular outflow tract (LVOT) obstruction immediately before transcatheter mitral valve replacement (TMVR). BACKGROUND: LVOT obstruction is a life-threatening complication of TMVR, caused by septal displacement of the AML. METHODS: The procedure was used in patients with severe mitral valve disease and prohibitive surgical risk...

A 79-year-old man with history of aortic stenosis, status post bioprosthetic aortic valve replacement, episodes of bacteremia, and endocarditis presented to hospital with fever. Clinical assessment led to suspicion of possible endocarditis. Initial interpretation of transesophageal echocardiogram was inconclusive without vegetation in mitral/aortic valve. An In-leukocyte scan demonstrated increased uptake in the area of aortic valve, suggestive of infection. Further review of the transesophageal echocardiogram showed signs of annular abscess...

Left ventricular outflow tract (LVOT) obstruction is a recognized complication of transcatheter mitral valve-in-valve replacement in previous surgical prostheses. We describe a patient who was high risk for repeat open surgery in whom the LVOT was compromised by a surgical strut and the potential for LVOT obstruction. A novel approach to avoiding this complication was utilized. A perfusion balloon was inflated in the outflow tract to provide an opposing force during mitral valve deployment resulting in less flaring of the strut into the outflow tract thereby improving the neo-LVOT area...

INTRODUCTION: A 71 year old Peruvian woman presented with blurry vision and bilateral eye pain and had evidence of bilateral endophthalmitis on eye examination. Her past medical history was notable for multiple abdominal surgeries within the preceding months, including an incarcerated inguinal hernia repair which required an ileostomy placement, and cholecystitis requiring cholecystostomy tube placement. Over her multiple long hospitalizations, she developed bacteremia and fungemia on several occasions, with organisms including Enterobacter cloacae, Klebsiella pneumoniae, Bacteroides fragilis, Pseudomonas aeruginosa, Enterococcus faecium, and Candida albicans...

Massive intracardiac and intravascular thrombosis is a rare complication following cardiopulmonary bypass (CPB). Most of the cases of the disseminated thrombosis have been reported in patients undergoing complex cardiac surgeries and those receiving antifibrinolytic agents during CPB. We report the occurrence of disseminated intravascular and intracardiac thrombosis after CPB in a patient undergoing mitral valve replacement in which no antifibrinolytic agent was used. The possible pathophysiology and management of the patient is discussed...

Mitral regurgitation is the most common valvular heart disease in western world, with moderate to severe mitral regurgitation having a deep impact on prognosis, mortality and rehospitalizations. Advanced congestive heart failure is frequently complicated by mitral regurgitation, a pathologic condition that is often under-diagnosed. A significant proportion of patients with severe mitral regurgitation is not eligible for surgery (mitral valve repair or replacement) because of contraindications or excessive surgical risk...

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term "cardiac surgery". Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal...

Few reports have described long-term outcomes after translocated mitral valve replacement. We describe tips, potential pitfalls, and long-term outcome associated with the construction of a new mitral annulus and reinforcement of prosthesis attachment using a mitral prosthetic valve with an equine pericardial collar in a woman with extensive mitral valve calcification.

INTRODUCTION: To facilitate coaxial device deployment in transcatheter mitral valve replacement (TMVR), a coaxial approach to the mitral annular plane is needed. We sought to establish a method to determine an 'orthogonal' left ventricular (LV) access point for transapical TMVR and to quantitatively characterize its location in patients with severe mitral regurgitation using cardiac computed tomography. METHODS: Cardiac CT data sets of 54 patients with moderate-severe mitral regurgitation evaluated for potential TMVR were analyzed...

AIMS: To identify the impact of previous aortic valve replacement (AVR) in Mitra-Clip (MC) patients. METHODS AND RESULTS: Data from the German Transcatheter Mitral Valve Interventions (TRAMI) registry were analyzed in light of previous AVR by means of either standard AVR (SAVR) or transcatheter AVR (TAVR). Out of 791 MC, 68 (8.6%) had been submitted to AVR (68.4% SAVR and 31.6% TAVR). AVR group was significantly older (77.2±8.0 years vs. 75.1±8.6 years; p<0...

Mitral valve morphology after mitral valve surgery affects postoperative intraventricular flow patterns and long-term cardiac performance. We visualized ventricular flow by echocardiography vector flow mapping (VFM) to reveal the impact of different mitral valve procedures. Eleven cases of mechanical mitral valve replacement (nine in the anti-anatomical and two in the anatomical position), three bioprosthetic mitral valve replacements, and four mitral valve repairs were evaluated. The mean age at the procedure was 57...
