An 86-year-old female patient was referred for treatment of symptomatic severe aortic stenosis. The heart team decided to perform transfemoral transcatheter aortic valve implantation. A 25 mm transcatheter aortic valve was implanted, but the valve migrated low into the left ventricular outflow tract. The subsequent removal and replacement procedures are described.

OBJECTIVE
Congenital mitral ring is a rare subtype of congenital mitral stenosis. Our objective is to review the anatomic findings and surgical results of this lesion and to identify early predictors of outcome.
METHODS
Clinical reports, echocardiographic studies, cardiac catheterizations, surgical reports, and follow-up data of all patients with mitral ring diagnosed at the Bambino Gesù Hospital were retrospectively reviewed.
RESULTS
Between January of 1987 and June of 2007, a mitral ring was diagnosed in 25 patients (13 male) with a mean age at diagnosis of 36 months. The ring was identified in a single neonate but seemed to develop and progress during infancy. All but 1 patient had associated cardiac anomalies. We identified 2 distinct subtypes: "intramitral ring" in 18 of 25 patients (72%), associated with complex valve pathology and a worse outcome, and "supramitral ring" in 7 of 25 patients (18%), in whom the mitral apparatus was usually normal and the outcome was better. The ring was surgically removed in 13 of 25 patients (52%) (mean Doppler gradient 15 +/- 4 mm Hg). The gradient decreased in 9 of 13 patients (mean diastolic transmitral gradient
8 mm Hg) in the other 4 patients, all with intramitral ring. All 4 patients underwent repeat mitral valvuloplasty. There were no operative or late deaths. CONCLUSION
Two types of congenital mitral ring, with diverse valve pathology and outcome, were identified. Rarely seen in neonates, the ring develops and often progresses during infancy. Recognition is important because surgical results are better than for other forms of congenital mitral stenosis.

Parachute mitral valve (PMV) is a common form of congenital mitral stenosis and is difficult to diagnose prenatally. This report describes a fetal case of PMV with coarctation of the aorta that was diagnosed at 25 weeks' gestation by echocardiography and confirmed at autopsy. We describe the ultrasonographic features in this case and present a useful sign for making a prenatal diagnosis of PMV.

BACKGROUND
Percutaneous balloon mitral valvotomy (PBMV) is generally considered as a contraindication in patients with mitral stenosis (MS) associated with moderate to severe mitral regurgitation (MR). We sought to compare the safety and efficacy of PBMV in patients with severe MS and with moderate MR with those with less than moderate or no MR.
MATERIALS AND METHODS
Symptomatic patients of MS with mitral valve area ≤1.5cm were screened into two groups: Group I with moderate MR and Group II with less than moderate or no MR. Clinical and echocardiographic assessments were done at 24h, 1 month, and 6 months post-procedure. A treadmill testing was done prior to PBMV and at 6 months. Primary safety outcome was a composite of cardiovascular death and development of severe MR with or without requirement for mitral valve replacement at 30 days of procedure. Efficacy of the procedure was measured as improvement in functional class, treadmill time, and mitral valve area (MVA) at 6 months.
RESULTS
Seventeen patients with moderate MR and 208 patients with less than moderate MR underwent PBMV. Primary outcome showed no significant difference [2 (11.7%) in Group I vs. 8 (3.85%) in Group II, p=0.36]; occurrence of severe MR was higher in Group I [RR=4.87, 95% C.I.=1.42-16.69]. In Group I patients, improvement in treadmill time was seen in 12 (70.59%), functional class in 13 (76.47%), and MVA in all patients.
CONCLUSION
In patients having severe MS associated with moderate MR, PBMV may be a safe option and provides sustained symptomatic benefit.

Review
PRINCIPLES
Percutaneous mitral balloon valvotomy is increasingly being carried out on patients with pure mitral stenosis, but discrepant results are still available at long-term follow-ups following percutaneous balloon and traditional surgical valvotomy. This research sought to systematically compare the efficacy and safety of mitral balloon and surgical valvotomy.
METHODS
A systematic literature retrieval was performed for all clinical trials comparing the outcomes of mitral valvotomy with balloon intervention or surgery in Pubmed, EMBASE and the Cochrane Library.
RESULTS
A total of 12 eligible, clinical studies, comparing mitral valvotomy using percutaneous balloon intervention or thoracotomy surgery, were found between 1966 and 2010: seven prospective randomised trials and five case-control trials. With follow-up ranging from one to seven years, there was no significant difference in mortality (relative risk (RR) 0.97, 95% confidence interval (CI) 0.45-2.09) and complications (RR 2.15, 95% CI 0.98-4.7) between the two procedures. The pooling analysis obtained a significantly higher occurrence of new-onset mitral regurgitation after percutaneous balloon intervention relative to thoracotomy surgery (RR 1.66 95%CI 1.08-2.58). Similarly, we obtained a higher RR of re-intervention in balloon intervention compared to thoracotomy surgery of 2.88 (95% CI 1.97-4.2). In addition, compared to those patients who had thoracotomy surgery, patients who underwent percutaneous balloon intervention presented a significantly worse effect in preserving the mitral valve area: SMD -0.30, 95%CI: -0.42 - -0.18.
CONCLUSIONS
Clinical evidence suggests there are comparable clinical outcomes in terms of operative, late mortality and complications between percutaneous balloon and surgical mitral commissurotomy. Incidences of new-onset mitral regurgitation and late re-intervention are significantly higher after balloon intervention.

Two cases of left atrial myxoma and concomitant, but unrelated mitral valve disease are reported. The first patient had severe mitral stenosis and mitral regurgitation due to rheumatic heart disease in addition to a large immobile left atrial myxoma. At surgery, the tumor was considered unresectable because of its size and widespread attachment to the left atrium. A mitral commissurotomy was performed with temporary improvement. The second patient had mitral regurgitation due to mitral valve prolapse (myxomatous degeneration) and an unrelated tumor. The patient's condition improved after mitral valve reconstruction and resection of the tumor. In both cases, the relatively immobile tumor was not physically in contact with the mitral valve and probably was not responsible for the valve disease. Both patients presented with dyspnea, to which the tumors may have contributed by causing partial obstruction of the pulmonary veins. Diagnostic and therapeutic problems resulting from the association of atrial myxoma and unrelated mitral valve disease are discussed.
