21/422. Low dose synthetic human atrial natriuretic peptide infusion in a patient with mitral stenosis and severe pulmonary hypertension.

    The present report concerns a case of very low plasma levels of atrial natriuretic peptide (ANP) accompanying severe pulmonary hypertension due to mitral stenosis. There was remarkable fibrosis in the atrium and ANP secretion may have been insufficient. Low-dose infusion (0.025 microg kg(-1) min(-1)) of synthetic human alpha-ANP infusion was very effective in improving the pulmonary hypertension.

22/422. erythropoietin in Jehova's witness heart surgery.

    The patients, reported here, needed open heart surgery, but religion obliged them to refuse blood transfusion. Three of the four patients suffered from obstructive coronary diseases and one from mitral valvular disease, prevalently stenosis. All of them refused blood transfusions. One of the three patients presented, was refused by an other Cardiovascular Surgery Center because of his low blood values (Haemoglobin 9.2--Haematocrit 26.7). All these patients had been treated with subcutaneous injection of epoetin alfa 10,000 U twice a week and ferrous sulphate 525 mg three time a day per os, for three weeks before operation. Haemoglobin, haematocrit and reticulocytes values were controlled in pre, postoperative and at discharge. With this treatment the authors found haemoglobin and haematocrit values so increased to allow surgery without blood transfusion during and in the post operative period.

23/422. Aberrant infrarenal inferior vena cava as a hindrance to percutaneous transvenous mitral valvuloplasty in a patient with mitral stenosis: case report.

    cardiac catheterization and percutaneous transvenous mitral commissurotomy using the Inoue technique were attempted in a 44-year-old woman with mitral stenosis. The pulmonary arterial wedge pressure was 25 mmHg, mean transmitral diastolic pressure gradient 20.3 mmHg, cardiac index 1.80 L/min/m2, and mitral valve area 0.70 cm2. After the diagnostic catheterization, the guide wire for the transseptal procedure was checked in the middle of the inferior vena cava (IVC). A 7-French end-holed Bermann catheter was then used to detect the course of the IVC. It was found that the IVC coursed along the left border of the 4th and 5th lumbar vertebrae, to the left of the abdominal aorta. At the upper border of the third lumbar vertebra, the IVC returned to the right side of the vertebra. In consideration of the inability to pass the Brockenbrough needle through the detoured infrarenal IVC and the risk of rupturing the vessel, the transseptal procedure and attempted percutaneous transvenous mitral commissurotomy were aborted. Therefore, the patient underwent open mitral commissurotomy instead.

24/422. Intraatrial mitral valve insertion with native valve preservation in children.

    Two patients underwent intraatrial mitral valve insertion for an unsuccessful valvotomy for severe mitral stenosis and left-sided atrioventricular valve insufficiency associated with corrected transposition utilizing a porcine valve from a valved conduit with preservation of the native valve. The valves were inserted using continuous suture distally at the mitral annulus and proximally at the pulled atrial wall distal to the pulmonary veins. Both patients had uneventful hospital course and are doing well at up to 6 months postoperatively. This approach provides a viable option for congenital mitral stenosis or insufficiency in children.

25/422. Maze procedure and homograft replacement of a rheumatic mitral valve.

    A 64-year-old woman presented with congestive heart failure due to severe mitral valve stenosis and chronic atrial fibrillation. A Maze III procedure was performed, and the mitral valve replaced with a mitral homograft. Postoperatively, the patient regained normal sinus rhythm, had trivial mitral regurgitation, regained her atrial transport function, and had improved myocardial function.

26/422. Successful inoue balloon mitral commissurotomy in double-orifice mitral stenosis.

    We report a rare case of stenotic double-orifice mitral valve of incomplete bridge type in a 40-year-old male. The fibrous bridge tissue between the leaflets was successfully split with a 24-mm Inoue balloon catheter using the stepwise dilation technique. Cathet. Cardiovasc. Intervent. 49:200-203, 2000.

27/422. Successful percutaneous balloon mitral valvuloplasty using left ventricular pressure as a guide to cross the mitral valve--a case report.

    Percutaneous balloon mitral valvuloplasty (PBMV) provides an effective alternative to surgery in a selective group of patients with symptomatic mitral stenosis. The Inoue balloon technique involves transseptal catheterization followed by catheter manipulation to cross the mitral valve. The authors describe a case of successful percutaneous balloon mitral valvuloplasty in a patient with severe mitral stenosis and pulmonary hypertension. Left ventricular systolic pressure was used as a guide to locate and to advance the balloon catheter across the mitral valve. This technique to cross the mitral valve has not been reported in the literature.

28/422. Mitral stenosis obscuring the diagnosis of plexogenic pulmonary arteriopathy and familial pulmonary hypertension.

    A patient who died after surgery for critical mitral stenosis was found to have underlying unrecognised plexogenic pulmonary arteriopathy and familial pulmonary hypertension. The importance of recognising familial pulmonary hypertension is discussed, together with the contribution of genetic and other risk factors to plexogenic pulmonary arteriopathy.

29/422. Transjugular approach to concurrent mitral-aortic and mitral-tricuspid balloon valvuloplasty.

    A transjugular approach was successfully used for concurrent mitral-aortic and mitral-tricuspid valvuloplasty in one patient each. This approach simplifies antegrade transvenous aortic valve dilatation in rheumatic aortic stenosis. Advantages obtained by transjugular tricuspid valvuloplasty are easy crossing of the tricuspid valve and stable balloon position, co-axial with the tricuspid orifice.

30/422. Stenosis of a mechanical mitral prosthetic valve in a patient with systemic lupus erythematosus.

    A young woman with systemic lupus erythematosus (SLE) developed progressive heart failure several years after mitral valve replacement with a Bjork-Shiley prosthesis for treating mitral stenosis due to Libman-Sacks endocarditis. She was admitted to the hospital with pulmonary oedema. Transoesophageal echocardiography revealed stenosis of the mitral prosthesis, which was covered by fibrous tissue. Replacement of the prosthesis was done but the patient died from cerebral haemorrhage three days later. Although three cases of prosthetic valve dysfunction in SLE have been documented so far, this is to our knowledge the first report of a SLE recurrence on a tilting disc mechanical valve.
