Mitral valve aneurysms are rare and occur most commonly in association with aortic valve endocarditis. Transesophageal echocardiography is the most sensitive imaging modality for the diagnosis of this entity and its potential complications, such as leaflet rupture and mitral regurgitation, which mandate prompt surgical intervention. We present the case of a 70-year-old male patient with aortic valve endocarditis complicated with a ruptured aneurysm of the anterior mitral valve leaflet and associated severe mitral regurgitation, diagnosed by transesophageal echocardiography, with impressive images...

Uniqueness of this case report is that though coronary cameral fistulas are itself rare, we closed fistula effectively in a different way. Since surgery was only good option available as patient had concomitant valvular disease, we closed distal end of fistula in PA and then took deep bites of suture in fistulous track itself. This approach closed fistula effectively and we had no need to dissect and ligate its origin from LAD which is more arduous and dangerous task.

Right atrial myxomas are rare. Its occurrence in a previously operated patient of rheumatic mitral stenosis posed clinical diagnostic challenge. We herein report a case of right atrial myxoma who had undergone mitral valve repair 20 years ago and now presented in congestive heart failure. The tumor was arising from the ostium of the coronary sinus and prolapsed into the right ventricle causing significant right ventricular inflow and outflow obstruction. Urgent repeat cardiac surgery was successfully performed to remove the tumor along with mitral valve replacement...

Enlargement of left atrium occurs in patients with longstanding mitral valve disease due to chronic pressure and volume overload and occasionally left atrium reaches a massive enlargement, condition known as giant left atrium. It is most commonly associated with rheumatic mitral valve disease, both stenosis and regurgitation. This unique case deals with a 70-year-old woman who developed a giant left atrium due to a severe mitral regurgitation from complete prolapse of both mitral leaflets, as a consequence of previous undersized mitral ring annuloplasty...

BACKGROUND: The optimal timing of surgery in patients with chronic organic severe mitral regurgitation (MR) continues to be debated, especially for those who are asymptomatic. The aim of the study was to determine independent and additive prognostic value of exercise brain natriuretic peptide (eBNP) in patients with severe asymptomatic MR and normal left ventricular ejection fraction (LVEF). METHODS: Two hundred twenty-three consecutive patients with severe MR defined by effective regurgitant orifice (ERO) area ≥ 40 mm(2) and/or residual volume ≥ 60 mL, LVEF > 60%, and normal LV end-systolic diameter < 40 mm underwent symptom limited exercise treadmill test (TMT)...

BACKGROUND: Prominent mitral valve (MV) annular dilatation with only modest left ventricular (LV) dilatation in patients with MV prolapse (MVP) suggests predominant dilatation in adjacent basal LV, which may augment regional wall tension and attenuate contraction by Laplace's law. We hypothesized that MV annular dilatation in patients with MVP is associated with the basal predominance of LV dilatation and attenuated contraction, which can be altered by surgical MV plasty with annulus reduction...

BACKGROUND: Repair of mitral regurgitation (MR) caused by prolapse has been well validated. Although favorable early and late results after repair have been reported, few data are available that mechanistically describe how a mitral repair fails beyond the mere need for mitral valve reoperation. We therefore sought to determine the modes of valve repair failure in patients who underwent surgical correction of MR caused by prolapse. METHODS: Between 2001 and 2015, 855 patients underwent repair of MR caused by prolapse...

BACKGROUND AND AIM: Artificial chordal implantation in order to repair flail or prolapse mitral valve leaflet requires open heart surgery and cardiopulmonary bypass. Transapical off-pump implantation of neochordae is a new surgical technique proposed to treat degenerative mitral valve regurgitation. The procedure is performed using the NeoChord DS1000 system (NeoChord, Inc., Eden Praire, MN), which facilitates both implantation and tension adjustment of the neochordae under transesophageal echocardiographic 2D and 3D guidance...

BACKGROUND: Sudden cardiac death (SCD) is frequently the first manifestation of underlying cardiovascular disease in young competitive athletes (YCAs), yet there are no Canadian guidelines for preparticipation screening in this population. The goal of this study was to determine the prevalence of potentially lethal cardiovascular disease in a sample of Canadian YCAs by comparing 2 screening strategies. METHODS: We prospectively screened 1419 YCAs in British Columbia, Canada (age 12-35 years)...

BACKGROUND: Morbidity and mortality risks in patients with end-stage renal disease (ESRD) undergoing mitral valve surgery are high; however, little is known regarding the risks and results of mitral valve repair in these patients. METHODS: We retrospectively reviewed the clinical data of dialysis-dependent patients who underwent mitral valve repair with the "respect" approach between April 2012 and April 2015 in our institution. RESULTS: All five identified patients survived and their data were included in the analysis...

Mitral regurgitation (MR) is a common valvular disorder that has important health and economic consequences. Standardized guidelines exist regarding when and in whom to perform mitral valve surgery, but little information is available regarding medical treatment of MR. Many patients with moderate or severe MR do not meet criteria for surgery or are deemed to be at high risk for surgical therapy. We reviewed the available published data on medical therapy in the treatment of patients with primary MR. b-blockers and renin-angiotensin-aldosterone system inhibitors had the strongest supporting evidence for providing beneficial effects...

Introduction. Fluid-attenuated inversion recovery hyperintense vessels (FHVs) can be seen in patients with occlusion or severe stenosis of the cerebral arteries. FHVs are known to reflect stagnant or slow blood flow within the cerebral artery. Case Report. A 75-year-old woman presented with suddenly developed gait disturbance. She had a history of hypertension, heart failure, and dementia. Brain MRI demonstrated FHVs within both middle cerebral arteries (MCAs). However, there was no acute ischemic lesion and severe stenosis or occlusion of the cerebral arteries...

Significant mitral valve disease with atrial fibrillation after heart transplantation is unusual. We report the diagnosis and minimally invasive surgical treatment 17 years after transplantation, in which mitral valve repair together with left atrial ablation was performed, resulting in a satisfying clinical and echocardiographic improvement.

The Framingham Heart Study group has described the non-diagnostic variants may evolve into mitral valve prolapse over time. These non-diagnostic variants include minimal systolic displacement, and abnormal anterior coaptation which is measured on surface echocardiography. Computed tomography and cardiac magnetic resonance imaging are evolving and can assess the degree of mitral regurgitation (MR); imaging techniques aside, genetic and proteomic detection of mitral prolapse is also evolving. However, the genetic basis for mitral prolapse is complex and likely involves multiple genetic loci...

Medullary sponge kidney (MSK) is a congenital renal disorder. Its association with several developmental abnormalities in other organs hints at the likelihood of some shared step(s) in the embryogenesis of the kidney and other organs. It has been suggested that the REarranged during Transfection (RET) proto-oncogene and the Glial cell line-Derived Neurotrophic Factor (GDNF) gene are defective in patients with MSK, and both RET and GDNF are known to have a role in the development of the central nervous system, heart, and craniofacial skeleton...

Systolic anterior motion of the mitral valve (SAM) occurs intraoperatively after mitral valve repair (MVRr) in up to 14% of cases and typically resolves in the operating room with conservative measures. Less commonly SAM may also occur in the early or late postoperative period. The clinical course and optimal management of such cases is poorly defined, but reoperation is common. We describe our experience using disopyramide to successfully treat postoperative SAM refractory to beta blockade. Seven patients were retrospectively identified with mitral valve prolapse who underwent MVRr from 2003 to 2015 and were found during follow-up to have severe SAM with a left ventricular outflow tract (LVOT) gradient not observed intraoperatively...

Mitral valve prolapse is a benign condition. Mitral regurgitation is only complicated in patients with severe mitral valve prolapse. Women with mitral valve prolapse in the absence of other cardiovascular disorders tolerate pregnancy well and do not develop remarkable cardiac complications. Nevertheless, serious complications of mitral valve prolapse, including arrhythmia, infective endocarditis and cerebral ischemic events, can be present in pregnancy. Debates remain with regard to the use of prophylactic antibiotics and β-blockers in the pregnant women with mitral valve prolapse...
