ABSTRACT
We report a case of emergent redo-mitral valve replacement during pregnancy at 23 week and 4 days of gestation. A 23-year-old woman, who underwent mitral valve replacement with a bioprosthetic valve (Carpentier-Edwards Perimount<sup>®</sup> 27 mm) for infective endocarditis 5 years ago, was transferred to our hospital due to severe congestive heart failure. Echocardiography revealed structural valve deterioration of the mitral prosthesis and severe mitral stenosis. Emergent redo-mitral valve replacement with a bioprosthetic valve was performed to save the patient with top priority. Cardiopulmonary bypass was operated under normothermic, high flow, high pressure and pulsatile fashion. Fetal heart rate was continuously monitored during the operation. Although her baby was delivered vaginally just after operation weighing only 520 g, she was treated by the neonatologists successfully.
ABSTRACT
A 37-year-old man presented with extensive myocardial infarction due to total occlusion of the left main trunk, complicated with near-fatal heart failure. An extracorporeal left ventricular assisted system LVAS (NIPRO-Toyobo LVAS) was implanted in our hospital. Although his postoperative course was relatively good, acute cholecystitis occurred on the 31st postoperative day, and emergeney cholecystectomy was indicated. His PT-INR was 4.13 because of taking Warfarin orally, and the cannulas of LVAS passed through his skin at the subxiphoid region. Therefore, we preoperatively transfused fresh frozen plasma quickly to reverse the PT-INR (approximately 2.0) and performed open cholecystectomy via the right side of the para-rectus abdominal muscle. His postoperative course was uneventful, and he is waiting for heart transplantation in our hospital.
ABSTRACT
We experienced 6 cases of intractable perioperative myocardial ischemia with coronary spasm that was successfully treated with fasudil, a Rho-kinase inhibitor. Three of the patients (aged 49-81 years) showed ST elevation on electrocardiograms and abrupt circulatory collapse after off-pump coronary artery bypass grafting. Emergeny coronary angiogram revealed severe spasm of their own coronary arteries and/or bypass grafts. Since intracoronary and/or intragraft injection of isosorbide dinitrate (ISDN) was ineffective, we administered fasudil into the spastic vessels, and that completely resolved the spasm. The other 3 patients (aged 55-77 years) suffered myocardial ischemia during the operation, though intravenous vasodilators including ISDN, diltiazem and nicorandil had been administered continuously. Their ischemia occurred when the aorta was declamped, the pericardium opened, or the bypass graft was anastomosed, respectively. We decided to use fasudil in these cases since ISDN was ineffective, or severe spasm was found on intraoperative inspection. Administration of fasudil successfully relieved the ischemia, and subsequently all 3 patients could be weaned from the cardiopulmonary bypass during the operation. Fasudil completely resolved the myocardial ischemia in all 6 patients. In conclusion, fasudil, a Rho-kinase inhibitor, is a useful agent for perioperative myocardial ischemia including coronary spasm that is resistant to intensive conventional vasodilator therapy. We should administer fasudil and relieve spasms as early as possible to rescue patients with intractable ischemia.
