Decalcification of Anterior Mitral Valve Leaflet to Repair Moderate Nonrheumatic Mitral Valve Stenosis with Severe Aortic Valve Stenosis / 日本心臓血管外科学会雑誌

A 78-year-old woman was referred to our hospital because of progressive exertional dyspnea due to nonrheumatic severe aortic valve stenosis and moderate mitral valve stenosis with mitral annular calcification. We subsequently performed aortic valve replacement and mitral anterior leaflet decalcification. During surgery, we found that the cause of mitral valve stenosis was calcification of A2 aortic curtain-medial trigon through aortic valve annulus and resected calcification with SONOPET. The postoperative echocardiography revealed good mitral valve motion with mild mitral valve stenosis.

Cardiac Tamponade due to Detachment of the Aortic Valve Commissure / 日本心臓血管外科学会雑誌

A 68-year-old man was taken to our hospital by ambulance due to syncope. He was in shock with cardiac tamponade. Pericardial drainage was performed. Aortic valve regurgitation gradually increased and surgery was performed at 25 days after onset. Surgical finding showed that there was a detachment of the commissure between the right and non coronary cusps of the aortic valve. An intimal tear was detected in the same place and aortic root replacement was required. The patient had a good recovery and he was discharged 14 days after surgery.

A Case of Septic Pulmonary Embolization due to Pacemaker Infection in Which Long-Term Perioperative Ventilation Was Required / 日本心臓血管外科学会雑誌

Septic pulmonary embolization (SPE) is an uncommon pulmonary disorder. The diagnosis of SPE is frequently delayed because of its nonspecific chest roentgenological features. A 76-year-old woman who underwent pacemaker implantation one year previously received antibiotic therapy under a diagnosis of infectious colitis. She suffered septic shock and disseminated intravascular coagulation (DIC) and was admitted to our hospital. Methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) was cultured from her blood and echocardiography demonstrated 13×16 mm vegetation originating from the tricuspid valve. Multiple peripheral nodules with cavitation were found on chest computed tomography and she was given a diagnosis of SPE. She rapidly presented acute respiratory failure and mechanical ventilation was inevitable for 23 days before surgery. She underwent removal of the entire pacing system, resection and repair of the tricuspid valve and epicardial pacemaker lead implantation. Tracheostomy and long-term mechanical ventilation (16 days) was required after surgery, however, she was discharged from our hospital without any complication.
