Degenerative mitral valve (MV) disease involving mitral prolapse is one of the most prevalent MV pathologies. Quadrangular leaflet resection and neochordoplasty demonstrate excellent clinical outcomes for the treatment of posterior leaflet prolapse. We evaluated the functional and biomechanical characteristics of a virtual pathologic MV model suffering from chordal rupture, performed virtual neochordoplasty and quadrangular leaflet resection, and compared the two post-repair MV functions. The pre-repair MV demonstrated severe posterior leaflet prolapse due to the ruptured P2 chordae and excessive stress concentration...

BACKGROUND: Left ventricular outflow tract obstruction (LVOTO) occurs from not only obstructive hypertrophic cardiomyopathy but also other conditions such as sigmoid septum or post mitral valve repair. However, the changes of the LVOT pressure gradient (LVOT PG) in LVOTO with various conditions remain unclear. METHODS: The clinical characteristics and echocardiographic parameters of 73 patients with LVOT PG ≥50 mmHg at rest on Doppler ultrasound were retrospectively investigated...

We present our experience for patients who have undergone an anatomic repair (AR) for congenitally corrected transposition of the great arteries (CCTGA) at the Children's Hospital of Wisconsin. A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male). Median age of anatomic repair was 15 months (range 4.5-45.6 months). Four patients had a bidirectional Glenn (BDG) prior to AR. At the time of AR,-9 (60%) underwent Senning/Rastelli procedure, 4 (26...

Quadruple-valve repair or replacement is associated with significant morbidity and mortality because the clinical situation of severe disease of all 4 valves implies incipient myocardial damage. We report a case of redo quadruple-valve repair in a patient with rheumatic heart disease who had undergone the Ross procedure 14 years earlier. He presented with heart failure. Cardiac evaluation revealed severe disease of all 4 valves, necessitating surgery. Because he was in advanced heart failure and all 4 valves were suitable for repair, a quadruple-valve repair was performed...

REVIEW
Maurice Beghetti
Pulmonary hypertension (PH) is diagnosed using cardiac catheterization and is defined as an elevation of mean pulmonary artery pressure (PAP) greater than 25 mmHg. Although invasive hemodynamics remains the gold standard and is mandatory for disease confirmation, transthoracic echocardiography (TTE) is an extremely useful non-invasive and widely available tool that allows for screening and follow-up, in particular, in the acute setting. TTE may be a valuable alternative, allowing for direct measurement and/or indirect assessment of PAP...

A 59-year-old female with Tetralogy of Fallot had a previous complete repair with RVOT patch enlargement. She developed subsequent severe symptomatic (NYHA III) pulmonary regurgitation with severe RV dilatation. She had a concomitant interstitial lung disease secondary to hypersensitivity pneumonitis that precluded her from cardiac surgery. After preprocedural assessment using computed tomography, echocardiography and invasive angiography we decided to implant a 29 mm Edwards Sapien 3 valve without pre-stenting...

The combination of ruptured aneurysm of the sinus of Valsalva and a bicuspid aortic valve is very rare in an elderly person. A 71-year-old man with ruptured aneurysm of the sinus of Valsalva and a bicuspid aortic valve had undergone an operation. He was admitted to his other hospital because of heart failure. He was transferred to our hospital to undergo treatment for ruptured aneurysm of sinus of Valsalva. At our hospital, echocardiography findings showed ruptured aneurysm of the sinus of Valsalva, a ventricular septal defect (VSD), and severe aortic regurgitation with moderate stenosis of the bicuspid aortic valve...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

PURPOSE: Left ventricular outflow tract (LVOT) dimensions are important for calculation of aortic valve areas and planning of valve repair. Mostly, LVOT areas are calculated from echocardiographic longitudinal measurements with the assumption of a round shape. Here, orthogonal phase contrast (PC) MRI with dynamic assessment of LVOT was compared to standard longitudinal cine MRI and 2D echocardiography. METHODS: In 19 patients with aortic stenosis (5 female; 69±10years), LVOT areas were determined on orthogonal PC images, either by planimetry (Aplan) or by two-diameter measurement (Aellip)...

Ascending aorta aneurysms (AsAA) are associated with a degeneration of the aortic wall tissue, which leads to changes in tissue mechanical properties. Risk factors for the development of the AsAA disease are recognized in patient age and gender, valve type, hypertension, diabetes mellitus, smoking history, and a prior diagnosis of Marfan syndrome. The present study aims to assess how such clinico-pathological factors can affect the mechanical properties of human dilated ascending aorta. Specimens of AsAA are excised from 68 patients who underwent elective AsAA surgical repair and stretched until rupture during the execution of uniaxial tensile tests...
