Case ReportsDelayed right-sided diaphragmatic rupture and laparoscopic repair with mesh fixation.
Diaphragmatic rupture is usually an immediate, left-sided complication of high-velocity thoraco-abdominal trauma. Here we present a rare case of delayed, right-sided diaphragmatic rupture and its laparoscopic mesh repair.

Surgical thrombectomy and simultaneous stenting for deep venous thrombosis caused by iliac vein compression syndrome (May-Thurner syndrome).
Iliac vein compression syndrome (May-Thurner syndrome) is characterized by left iliac vein obstruction secondary to compression by the right common iliac artery against the fifth-lumbar vertebra, which increases incidence of deep venous thrombosis (DVT). We treated the patients with DVT due to May-Thurner syndrome (MTS) by surgical thrombectomy and simultaneous stenting, and this study is to evaluate the outcomes of this procedure. ⋯ Venous thrombectomy with simultaneous stenting is a potent technique to treat acute iliofemoral DVT due to MTS. This technique can restore venous patency and provide relief of the acute symptoms.

Mitral valve plasty for idiopathic rupture of mitral valve posterior chordae in infants.
Idiopathic mitral valve chordal rupture is rare among infants. Once it has occurred, acute heart failure progresses, and emergency surgical repair is necessary in most cases. Our surgical experience with idiopathic mitral valve chordal rupture is reported. ⋯ Mitral valve plasty was performed for idiopathic mitral valve chordal rupture in infants. The surgical procedures were the same as for adult cases and achieved satisfactory results.

Case ReportsStructural valve deterioration of porcine bioprosthesis soon after mitral valve repair and replacement.
An 81-year-old woman, who had undergone mitral valve replacement (MVR) with a porcine bioprosthesis after mitral valve repair, presented with hemolysis 4 years and 6 months after MVR. Transthoracic echocardiography (TTE) revealed trivial mitral regurgitation, which was diagnosed based on the observed perivalvular leakage. Hemolysis gradually increased, and she developed dyspnea and edema 2 years after the appearance of mitral regurgitation. ⋯ The postoperative course was uneventful. Microscopic examination verified collagen degeneration, histiocyte infiltration, and hyalinization. It is important to perform TEE to rule out structural valve deterioration (SVD) even when regurgitation occurs soon after valve replacement.
