Severe mitral regurgitation (MR) confers an adverse prognosis, frequently with debilitating symptoms of heart failure. While open surgical correction has been the standard of care for decades, novel catheter-based technologies have emerged that are highly effective in the treatment of MR. These percutaneous technologies, which include methods for both repair as well as valve replacement, have the potential to address unmet clinical needs in patients with MR, and serve as a viable alternative to surgery.

BACKGROUND: To determine if preoperative embolic stroke is associated with an increased risk of postoperative stroke among patients undergoing early operation for mitral valve (MV) infective endocarditis (IE), we compared outcomes among patients presenting with and without acute stroke. METHODS: From 2003 to 2015, 243 consecutive patients underwent surgery for active MV IE. Patients were categorized into 2 groups: 72% (174 of 243 patients) with no preoperative acute stroke (clinical, radiographic or both) and 28% (69 of 243 patients) with stroke...

OBJECTIVES: Blood lactate is frequently used to guide management in critically ill patients. In patients undergoing mitral valve surgery, an elevated lactate level is frequently observed; however, overall mortality is low. The authors hypothesized that hyperlactemia is not a useful predictor of poor outcomes in this patient population. The main aim of this study was to explore how blood lactate level and lactate clearance are associated with 30-day mortality and major adverse events in patients undergoing mitral valve surgery...

Mitral regurgitation (MR) is the second most common valvular heart disease referred for corrective surgery. Diagnostic and management dilemmas are not uncommon when dealing with MR patients. Exercise testing plays an important role in sorting out some of these clinical challenges. In primary asymptomatic MR, exercise testing allows symptom assessment, confident link of symptoms to valve disease severity, safe deferral of surgery for the next 1-year in patients with preserved exercise capacity, insights into the mechanism of exercise-induced dyspnea and helps in individual risk stratification...

The circulatory system consists of the heart, blood vessels and lymphatic vessels, which function in parallel to provide nutrients and remove waste from the body. Vascular function depends on valves, which regulate unidirectional fluid flow against gravitational and pressure gradients. Severe valve disorders can cause mortality and some are associated with severe morbidity. Although cardiac valve defects can be treated by valve replacement surgery, no treatment is currently available for valve disorders of the veins and lymphatics...

Asymptomatic "paradoxic" severe low-flow low-gradient aortic stenosis with preserved ejection fraction (PAS) constitutes a challenging condition where the optimal management and follow-up remain elusive. We evaluated the clinical outcome in patients with PAS as compared to asymptomatic patients with moderate (MAS) or classical severe aortic stenosis (CAS). Consecutive asymptomatic moderate or severe aortic stenosis patients without concomitant other heart or lung disease (n = 121) were invited. Participants (n = 74) were assigned to three subgroups with regard to degree of aortic stenosis: MAS (n = 25), CAS (n = 22) and PAS (n = 27)...

OBJECTIVE: Treatment monitoring and outcome evaluation in pediatric hydrocephalus require gapless documentation regarding surgical and clinical follow-up data beginning from day 1 of treatment in order to apply high quality of care. Endoscopic procedures, shunt insertion and revision surgeries, and individual modifications of valve hardware or pressure settings during follow-up as well as established outcome measurements are highly relevant for complete illustration of the patient's hydrocephalus histories...

BACKGROUND: In modern rhinoplasty, septal cartilage is the most commonly used graft material. It is a big challenge if septal cartilage is insufficient. We present an alternative technique named the "rabbit flap," created from the cephalic portion of the lower lateral cartilage to show its effectiveness on nasolabial angle, nasal axis deviation, and nasal dorsal line. METHODS: An alternative flap, called a "rabbit flap," is constituted from the cephalic portion of the lower lateral cartilage (LLC)...

Mitral valve prolapse (MVP) is a common heritable valvulopathy affecting approximately 2.4% of the population. It is the most important cause of primary mitral regurgitation (MR) requiring surgery. MVP is characterized by fibromyxomatous changes and displacement of one or both mitral leaflets into the left atrium. Echocardiography represents the primary diagnostic modality for assessment of MVP. Accurate quantitation of ventricular volumes and function for surgical planning in asymptomatic severe MR can be provided with both echocardiography and cardiac magnetic resonance ...

Bleeding after cardiac surgery or cardiovascular interventions is associated with worse patient outcome. Only very limited data are available on the subject of bleeding after percutaneous edge-to-edge mitral valve repair (PMVR). We performed a single center analysis including 347 consecutive patients who underwent PMVR. Bleeding was defined according to the Mitral Valve Academic Research Consortium (MVARC) end point definition. The incidence of MVARC bleeding was 21.6% (n = 75), whereas major MVARC bleeding (hemoglobin decrease ≥3 g/dl) occurred in 7...

BACKGROUND: Prosthetic valve endocarditis (PVE) due to methicillin resistant Staphylococcus aureus (MRSA) is a rare disease with significant mortality and morbidity. With the emerging resistance and adverse effect profile of vancomycin which is the standard treatment, there is a compelling necessity of an effective alternative for vancomycin. Linezolid is proved as such an agent for infections caused by MRSA in other sites. However to-date the evidence for successful use of linezolid for MRSA prosthetic valve endocarditis is limited only for few case studies...

BACKGROUND: The prevalence of congenital heart disease (CHD) in the adult population is steadily increasing. A substrate of prosthetic material and residual lesions, constantly evolving as surgical techniques change over time, predispose these patients to the potentially devastating complication of infective endocarditis (IE). METHODS: We retrospectively reviewed 2935 patients in our adult CHD database for all cases of endocarditis between 1991 and 2016. Incidence, clinical course and predictors of outcomes were analysed...
