Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%...

OBJECTIVE: Mitral annular structure and dynamics after mitral ring annuloplasty using transesophageal echocardiography during the operation have been reported. We evaluated mitral annular structure and dynamics of three different rings in the mid-term period postoperatively. METHODS: Thirty-one patients underwent mitral valve repair for degenerative mitral insufficiency. The MEMO 3D ring (semi-flexible), Carpentier-Edwards Physio II ring (semi-rigid), and St. Jude Medical Rigid Saddle Ring (rigid) were implanted in 15, 12, and eight patients, respectively, from September 2009 to February 2015...

Tricuspid valve regurgitation is frequently found as a result of right ventricular remodeling due to advanced left heart diseases. Drug treatment is limited to diuretics and the cardiac or pulmonary comorbidities. Due to the high risk only a small percentage of patients are amenable to surgical treatment of tricuspid regurgitation in those who undergo left-sided surgery for other reasons. Catheter-based procedures are an attractive treatment alternative, particularly since the strong prognostic impact of tricuspid regurgitation suggests an unmet need of treatment, independent of the underlying heart disease...

INTRODUCTION: The presence of symptoms, systolic dysfunction and Left Ventricle (LV) dilation are considered unfavourable prognostic markers in Aortic Valve Insufficiency (AVI). The role of diastolic dysfunction, which is considered unfavourable outcome marker in cardiac pathologies, is not well established in AVI. AIM: To evaluate if the presence of diastolic dysfunction may be associated with unfavourable prognostic markers in AVI patients. MATERIALS AND METHODS: A cross-sectional prospective study was performed on 22 patients with moderate or severe AVI...

Marfan syndrome is rarely diagnosed in the neonatal period because of variable expression and age-dependent appearance of clinical signs. The prognosis is usually poor due to high probability of congestive heart failure, mitral and tricuspid regurgitations with suboptimal response to medical therapy and difficulties in surgical management. The authors have studied two cases of Marfan syndrome in the newborn period. Two cases of neonatal Marfan syndrome, one male and one female, were diagnosed by characteristic physical appearance...

Ischemic mitral regurgitation (IMR) is a form of mitral insufficiency that is characterized by papillary muscle (PM) displacement, leaflet tethering, reduced closing forces, and different degree of annular dilatation. Treatment of this condition includes mitral valve replacement or mitral valve repair with restrictive annuloplasty. Recent evidences in mitral valve repair showed that addressing only the annulus and neglecting the subvalvular apparatus provides a suboptimal operation with poor long-term results...

BACKGROUND: Ischaemic mitral regurgitation (IMR) is associated with adverse prognosis after myocardial infarction (MI) as a result of left ventricular remodelling and geometric deformation of the mitral apparatus (MA). AIM: The aim of this study was to assess MA from anatomically correct imaging planes in acute inferoposterior MI and IMR. METHODS: Ninety-three patients with no structural cardiac valve abnormalities and the first acute inferoposterior MI were prospectively enrolled into the study...

OBJECTIVE: Patients undergoing multiple valve surgery represent a high-risk group who could potentially benefit from a reduction of cross-clamp and cardiopulmonary bypass times because prolonged bypass and cross-clamp times are considered independent risk factors for increased morbidity and mortality after cardiac surgery. METHODS: Between July 2013 and November 2014, 16 patients underwent rapid deployment aortic valve replacement with the EDWARDS INTUITY valve system in the setting of concomitant mitral disease...

We report three cases of coronary fistula aneurysm associated with mitral valve insufficiency. The patients were referred to our cardiovascular department because of exertional dyspnea. Echocardiography showed severe mitral valve insufficiency resulting from leaflet flail or prolapse and normal left ventricular function. In all three cases, preoperative coronary angiography showed coronary-to-pulmonary artery fistula associated with significant aneurysm of the fistulous tract. All patients underwent uneventful mitral valve repair and external ligation of the fistulas...

Braak and Del Tredici have proposed that typical Parkinson disease (PD) has its origins in the olfactory bulb and gastrointestinal tract. However, the role of the olfactory system has insufficiently been explored in the pathogeneses of PD and Alzheimer disease (AD) in laboratory models. Here, we demonstrate applications of a new method to process mouse heads for microscopy by sectioning, mounting, and staining whole skulls ('holocranohistochemistry'). This technique permits the visualization of the olfactory system from the nasal cavity to mitral cells and dopamine-producing interneurons of glomeruli in the olfactory bulb...

Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will allow a more expeditious indication for surgical treatment, as is already the case in mitral valve repair. This change of attitude will certainly make it possible for patients to be sent for operation in mild aortic valve regurgitation...
