Valvular hemangioma incidence is extremely low. In this report, we describe a 62-year-old man who presented with mild edema of the lower limbs. An echocardiogram revealed an incidental 1.3-cm diameter mass on the anterior mitral valve leaflet for which he underwent surgical resection and mitral valve replacement. Histopathological examination showed a lymphocyte-rich capillary-cavernous hemangioma. The exuberant lymphoid stroma is unusual for hemangioma and represents an undescribed pattern of cardiac hemangioma...

OBJECTIVE: Current techniques for mitral valve repair (MVR) in Barlow's disease require high level of surgical expertise due to a complex anatomy. A novel and simple standardized technique that particularly considers the pathological changes of the mitral valve in Barlow's disease has been developed. METHODS: Between 2009 and 2013, 22 patients underwent minimally invasive MVR for Barlow's disease and severe mitral regurgitation (MR). A simple, standardized technique was applied, including resection of P2 segment of posterior mitral leaflet (PML) with preservation of the shortest chordae, transfer of the preserved chordae to A2, and implantation of a semi-rigid open ring...

OBJECTIVES: Totally endoscopic minimally invasive mitral valve surgery (MIMVS) is technically demanding and often performed with robotic assistance. We hypothesized that three-port video-assisted thoracic surgery (VATS) would facilitate endoscopic MIMVS and evaluated its feasibility and safety. METHODS: From October 2010 to June 2016, we performed first-time MIMVS in 250 consecutive patients (122 male), with median age of 65 years (54-73 years, 25-75 percentile)...

OBJECTIVES: We assessed vortex patterns and energy loss in left ventricular flow in patients who underwent mitral valve repair or replacement with bioprosthetic valves. METHODS: Vector flow mapping was performed before and after the procedure in 15 and 17 patients who underwent repair and replacement, respectively. The preprocedure mitral-septal angle was measured in all patients. Relationships between vortex patterns or energy loss change (ELC) and annuloplasty ring or bioprosthetic valve sizes or the effect of mitral leaflet resection in the repair group were statistically analysed...

OBJECTIVES: To investigate short- and long-term outcomes of a conservative decalcification approach in mitral valve replacement (MVR) surgery in the presence of mitral annulus calcification (MAC). METHODS: Of the 1038 patients who underwent MVR, 133 (13%) had significant MAC with at least 30% of the annular circumference heavily calcified. In most patients, the surgical approach to MAC included conservative decalcification, supra-annular prosthesis implantation and insertion of a pericardial patch between the MV annulus and the prosthesis...

OBJECTIVES: Severe cases of infective endocarditis (IE) of the aortic valve can cause aortic root destruction and affect the surrounding structures, including the aortic-mitral continuity, the anterior mitral valve leaflet and the roof of the left atrium. Reconstruction after resection of all infected tissue remains challenging. We describe our surgical approach and the mid-term results. METHODS: Between January 2004 and December 2015, 35 patients underwent surgery for extensive IE of the aortic valve with destruction of the aortic root, the aortic-mitral continuity and the mitral valve...

Left ventricular free wall rupture is a complication following acute myocardial infarction or mitral valve replacement. We report the case of a 56-year-old female patient with idiopathic left ventricular rupture confirmed by contrast-enhanced computed tomography (CT). CT also showed no coronary artery obstruction and severe mitral annular calcification. Left ventricular rupture was successfully repaired internally with bovine pericardium. Mitral valve replacement with annular decalcification was also performed...

OBJECTIVES: Atrial fibrillation (AF) is common in patients with hypertrophic cardiomyopathy (HCM) and it is often poorly tolerated because of loss of atrial contraction and reduced filling time with rapid ventricular rates. Restoring sinus rhythm is of great clinical benefit to HCM patients. Very few data exist regarding surgical ablation of concomitant AF in this setting. The aim of this study was to evaluate the mid-term outcome of surgical AF ablation in patients who underwent cardiac surgery due to HCM...

BACKGROUND: Mycobacterium goodii is an infrequent human pathogen which has been implicated in prosthesis related infections and penetrating injuries. It is often initially misidentified as a gram-positive rod by clinical microbiologic laboratories and should be considered in the differential diagnosis. CASE PRESENTATION: We describe here the second reported case of M. goodii endocarditis. Species level identification was performed by 16S rDNA (ribosomal deoxyribonucleic acid) gene sequencing...

BACKGROUND: The aim of this study was to compare treatment of moderate to severe symptomatic mitral regurgitation (MR) with either conventional surgery or the mitral valve edge-to-edge device (MitraClip®) in very elderly patients. The newly introduced MitraClip device has demonstrated promising acute results in treating this patient cohort. Also noteworthy is the fact that patients who otherwise would have been denied surgery are increasingly referred for treatment with the MitraClip device...

Acute cholecystitis (AC) may be a severe problem and may increase the mortality rate and hospital stay in patients who undergo open heart surgery (OHS), due to its aggressive course; therefore, AC should be treated as soon as possible. We aimed to present data on our synchronous cardiac and laparoscopic cholecystectomy (LC) operations performed for AC complicating patients with cardiac disease and who were waiting to undergo OHS. Between January 2008 and September 2014, we performed 2773 OHSs in Medical Park Gaziantep Hospital...

An 84-year-old man presented 5 years following bioprosthetic mitral valve replacement with three months of worsening dyspnea on exertion. A new mitral stenosis murmur was noted on physical examination, and an electrocardiogram revealed newly recognized atrial fibrillation. Severe mitral stenosis (mean gradient = 13 mmHg) was confirmed by transthoracic echocardiography. Transesophageal echocardiography revealed markedly thickened mitral bioprosthetic leaflets with limited mobility, and a massive left atrial thrombus (> 4 cm in diameter) (see Figures 1A-D, and video files 1-4)...

Accurate evaluation of trans-aortic valvular pressure gradients is challenging in cases where dual mechanical aortic and mitral valve prostheses are present. Non-invasive Doppler echocardiographic imaging has its limitations due to multiple geometric assumptions. Invasive measurement of trans-valvular gradients with cardiac catheterization can provide further information in patients with two mechanical valves, where simultaneous pressure measurements in the left ventricle and ascending aorta must be obtained...

The development of paravalvular leak (PVL) following surgical replacement of an aortic or mitral valve is an uncommon complication with significant morbidity and mortality. Surgical or percutaneous repair of PVL can be technically challenging. We describe the application of intracardiac echocardiography guided 3-dimensional electroanatomic mapping to facilitate PVL closure in a symptomatic patient with a previously placed bioprosthetic mitral valve. © 2017 Wiley Periodicals, Inc.

Transcatheter aortic valve replacement is standard of care for patients with severe aortic stenosis at high risk for surgical aortic valve replacement. Although not intended for treatment of primary aortic insufficiency, several transcatheter aortic valve prostheses have been used to treat patients with severe aortic insufficiency (AI), including patients with left ventricular assist devices (LVAD), in whom significant AI is not uncommon. Similarly, transcatheter valve replacements have been used for valve-in-valve treatment, in the pulmonary, aortic, and mitral positions, either via a retrograde femoral approach or antegrade transseptal approach (mitral valve-in-valve)...

Congenitally corrected transposition of the great arteries (CTGA) is a rare congenital heart disease. In patients with functional CTGA with circumflex artery occlusion and mitral regurgitation (MR), the right ventricle functions as the left ventricle. Coronary artery bypass grafting with mitral valve replacement is an effective treatment for CTGA with concomitant myocardial infarction (MI) and MR.
