11/422. String-plucking as a mechanism of chordal rupture during balloon mitral valvuloplasty using inoue balloon catheter.

    Percutaneous transvenous mitral commissurotomy using the Inoue technique was performed in a 59-year-old female with mitral stenosis and a severely calcified mitral leaflets. Although not entrapped in the subvalvular apparatus, the balloon catheter was deviated away from the mitral orifice-apex axis of the left ventricle during the inflation of the proximal balloon, which plucked and severed the chordae tendineae of the posterior mitral leaflet and resulted in severe mitral regurgitation.

12/422. Clinical and echocardiographic features of two large left atrial parietal thrombi.

    A 62-year-old woman with severe mitral stenosis and two large parietal thrombi inside the left atrium is described. The patient was admitted to the hospital because of heart failure. Transthoracic and transesophageal echocardiography showed a severe calcific mitral stenosis and two large (56.9 and 46.2 mm in diameter) parietal thrombi inside the left atrium attached to the interatrial septum and associated with severe spontaneous echo contrast. This severe spontaneous echo contrast was detected in the left atrium and in the left atrial appendage. The patient was referred for cardiac surgery. The two large parietal thrombi were removed, and the valve was replaced with a Sorin-Bicarbon mitral valve prosthesis. Intraoperative transesophageal echocardiography after replacement of the mitral valve prosthesis and removal of the thrombotic mass showed absence of any spontaneous echo contrast in the left atrium and in the left atrial appendage. This report describes the diagnostic approach and successful surgical treatment of two very large parietal thrombi inside the left atrium associated with severe mitral stenosis and atrial fibrillation, which is a rare occurrence.

13/422. Successful Cox-maze III procedure combined with mitral valve replacement in a massively thrombosed left atrium.

    A case is reported of chronic atrial fibrillation resulting from long-standing rheumatic mitral stenosis complicated by a massively thrombosed left atrium. In this patient, restoration of sinus rhythm and atrial transport function was performed using a Cox-maze III procedure with mitral valve replacement.

14/422. Balloon dilatation of congenital mitral stenosis in a critically ill infant.

    We report a case of a 14-month-old-infant with severe congenital mitral stenosis who presented with pulmonary oedema, acute renal failure and haemodynamic instability. Balloon dilatation was successfully performed under fluoroscopic and transesophageal echocardiographic guidance. Cathet. Cardiovasc. Intervent. 48:191-193, 1999.

15/422. Definitive percutaneous treatment of Lutembacher's syndrome.

    Definitive percutaneous treatment of a patient with Lutembacher's syndrome was successfully accomplished using the Amplatzer septal occluder to close a secundum atrial septal defect and the Joseph mitral balloon catheter to dilate rheumatic mitral valve stenosis. Transcatheter therapy is an effective alternative to surgery in selected patients with Lutembacher's syndrome. Cathet. Cardiovasc. Intervent. 48:199-204, 1999.

16/422. Mital valve disease with rheumatic appearance in the presence of left ventricular endomyocardial fibrosis.

    This is a report of a nine-year-old boy with both mitral stenosis and regurgitation and extensive endomyocardial fibrosis of the left ventricle. Focus is given to the singularity of the fibrotic process, with an emphasis on the etiopatho-genic aspects.

17/422. Combined spinal-epidural analgesia in the management of labouring parturients with mitral stenosis.

    We report the use of combined spinal-epidural analgesia during labour in three parturients with moderately severe mitral stenosis. In each case, rapid analgesia was achieved using intrathecal fentanyl 25 micrograms without major haemodynamic changes. maintenance analgesia was then established gradually using a dilute epidural infusion of bupivacaine 0.1% and fentanyl 0.0002%, with the avoidance of large or rapid boluses of local anaesthetic. Supplementary analgesia in the latter stages of labour was provided using slow epidural boluses of fentanyl, with or without a low concentration of bupivacaine, which was sufficient to allow controlled instrumental deliveries. We conclude that combined spinal-epidural analgesia is a useful technique for providing analgesia and maintaining haemodynamic stability in parturients with mitral stenosis.

18/422. Mitral restenosis in the early postoperative period of a patient with systemic lupus erythematosus.

    A forty-eight year old woman, who had undergone mitral comissurotomy and subsequently developed early restenosis, presented with major comissural fusion and verrucous lesions on the cuspid edges of the mitral valve, with normal subvalvar apparatus. Patient did well for the first six months after surgery when she began to present dyspnea on light exertion. A clinical diagnosis of restenosis was made, which was confirmed by an echocardiogram and cardiac catheterization. She underwent surgery, and a stenotic mitral valve with verrucous lesions suggesting Libman-Sacks' endocarditis was found. Because the diagnosis of systemic lupus erythematosus (SLE) had not been confirmed at that time, a bovine pericardium bioprosthesis (FISICS-INCOR) was implanted. The patient did well in the late follow-up and is now in NYHA Class I.

19/422. Regression of large atrial thrombi and coronary neovascularizations with conventional anticoagulation in mitral stenosis--a case report.

    The authors report a case of angiographically documented multiple coronary neovascularizations originating from the left circumflex artery (LCX) and coursing toward multiple thrombi located in the left atrium in a patient with severe mitral stenosis. The thrombi as well as the neovascularizations underwent near-complete resolution with 4 weeks' anticoagulation therapy with warfarin maintaining an international normalization ratio of 3.5. Percutaneous mitral balloon valvuloplasty was performed successfully without complications.

20/422. Papillary fibroelastoma of the mitral valve 12 years after mitral valve commissurotomy.

    A 63 year-old woman who had had mitral valve commissurotomy 12 years earlier was seen because of rheumatic mitral stenosis and left brachial paresis due to cerebral embolism. On clinical evaluation, a diastolic rumble was heard over the mitral area, and the echocardiogram revealed a mass attached to the mitral subvalvular apparatus. The patient was operated on, and both the surgical and histologic findings depicted papillary fibroelastoma. This tumor may occur as an isolated lesion or be associated with mitral valve stenosis or other cardiac abnormalities, and it is an important source of emboli. Early echocardiographic diagnosis, followed by surgical excision, may avoid serious complications such as stroke, myocardial infarction, and sudden death.
