[Application of extended transseptal approach for a patient with chronic atrial fibrillation caused by mitral stenosis and tricuspid regurgitation].

A 45-year-old female of mitral valvular disease with chronic atrial fibrillation was referred to our hospital. She had received previous closed mitral commissurotomy (12 years ago) and open mitral commissurotomy combined with aortic valve replacement (6 years ago). An echocardiogram showed restenosis and regurgitation of the mitral valve (valve area 1.2 cm2 by B-mode) and severe regurgitation of the tricuspid valve. She also complained of chronic atrial fibrillation since 35 years old. Mitral valve replacement with CarboMedics bileaflet valve (25 mm) and tricuspid annuloplasty by DeVega procedure was undergone via an extended transseptal approach and cryoablastion was added to the posterior wall of the left atrium along the rim of the left pulmonary veins and around the left atrial appendage for ablation of chronic atrial fibrillation. After completion of surgery, atrial fibrillation disappeared. Post operative echocardiogram showed apparent atrial kick of both atriumns in the inflow pattern of both ventricles. The patient continues to be well with normal sinus rhythm for 6 months after surgery. An extended transseptal approach is useful in mitral reoperation, in addition, it can be applicable for the surgery of chronic atrial fibrillation.

Findings of transesophageal echocardiographic images in placing the coronary sinus perfusion catheter.

In retrograde cardioplegia (RCP), some difficulty is occasionally encountered when inserting a catheter into the coronary sinus (CS). Although the usefulness of transesophageal echocardiography (TEE) for guiding the cannulation procedures has been previously reported by other authors, we have obtained additional findings by TEE monitoring of eleven patients during placement of the CS catheter. The diameter of the CS ranged from 5.5 to 10.7 mm, indicating that it was large enough for the CS catheter to be inserted and that the resistance at insertion was not due to narrow CS. The precise time for inserting the catheter, for which myocardial protection is delayed, ranged from 8 to 376 seconds, with an average of 98 seconds. Dislodgement of the catheter was found in two cases. In case of difficult cannulation, the catheter tip was found to be pushing the right atrial wall adjacent to the CS orifice or alternatively it entered the middle cardiac vein which had a common atrial orifice with the CS in this particular case. We found that the knowing the following technical problems helps appropriate monitoring: the catheter tip becomes unclear when it is not perpendicular to the ultrasonic beam, when surgeon's fingers are placed behind the heart, or when the blood is entirely exsanguinated. Finally we present the possibility of employing images of overflow out of CS during RCP infusion, detected by TEE, as an index of efficient perfusion at the interventricular septum.

[A case of gastric cancer occurred after coronary artery bypass grafting using the right gastroepiploic artery].

We experienced a rare case of the gastric cancer occurred after the coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA). On April, 1990, a 74-year-old woman underwent CABG using RGEA for angina pectoris due to 99% stenosis of the right coronary artery. Anorexia and vomiting appeared from December 1992. Examination of the stomach by an oral procedure led to a diagnosis of the pyloric stenosis due to the gastric cancer. The coronary arterial lesion was progressive, and 90% stenosis of LAD (#6, #7) was noted. On February 1993, the re-CABG and the gastrectomy were performed simultaneously. The re-CABG using the saphenous vein was performed to #3, and additional CABG using the bilateral internal thoracic artery were performed to #8 and #9. At the same time, the gastrectomy were performed and RGEA was resected to remove the R2 lymph node completely. If the root of RGEA had been exposed completely at the first operation, RGEA could be preserved as the bypass graft.

[A case of mitral valve replacement for Libman-Sacks endocarditis].

A 38-year-old female was admitted to our hospital because she was suffered from severe dyspnea on effort. She had a history of nasal bleeding, endocarditis, fever, proteinuria, and alopecia at the age of 16, and was diagnosed as SLE. She was suffered from recurrent cerebral infarctions at the age of 35 and 38, and then mitral regurgitation was pointed out. Preoperative examination revealed non-active phase of SLE and UCG showed massive mitral regurgitation. Operative findings showed thrombosed verrucca circumferentially on the mitral valve. Mitral valve replacement (B-S #27) was done with using a felt strip in order to reinforce the mitral annular tissues. Histological findings of the verrucca showed Libman-Sacks endocarditis. Postoperative course was uneventful. Surgical treatment for Libman-Sacks endocarditis is extremely rare.

[Valvuloplasty for mitral regurgitation associated with acromegaly: report of a case].

A 67-year-old female with mitral regurgitation associated with acromegaly was admitted to our hospital. The cause of MR was torn chordae of posterior leaflet of the mitral valve. A prolapse part of the posterior leaflet was resected and sutured by McGoon's method. Annuloplasty was performed by Kay's method. Postoperative course was uneventful. She recovered well after the operation.

[A case of delayed ascending aortic pseudoaneurysm after traffic injury mimicking cardiac tumor].

A 44-year-old man was transferred to our hospital because of severe congestive heart failure complicated with acute renal failure and hepatic failure. He had been injured in a traffic accident three years before. Echocardiogram demonstrated a large tumor on the anterior wall of right ventricle obstructing RV outflow. Emergent operation was performed with cardiopulmonary bypass. Tumor was too large and invading into RV endocardium partially. RV patch enlargement was performed because it was impossible to resect tumor entirely. CVP was decreased dramatically to 8 cmH2O from 28 cmH2O. Postoperative hemodynamic was stable, but patient died of hepatic failure. Autopsy revealed that tumor was pseudoaneurysm from ascending aorta and ruptured into right ventricle.

[Coronary artery bypass grafting using the right gastroepiploic artery--an experience of simultaneous operation].

Coronary artery bypass grafting using the right gastroepiploic artery and cholecystectomy were simultaneously performed on a 62-year-old woman with both angina pectoris and cholecystolithiasis, with good results being obtained. No case of combined surgery with such coronary bypass has been reported yet. The present simultaneous surgery from our recent experience was regarded as a very useful surgical approach because of only one possible risk of surgical complications such as anesthetic accident, infection, etc, and of easy availability of the right gastroepiploic artery at laparotomy for coronary artery bypass grafting requiring some arterial graft.

[Successful correction of incomplete endocardial cushion defects in an elderly patient].

We have experienced surgical correction of incomplete ECD in a 66-year-old female patient. This is the oldest case in Japanese literatures. Preoperative examination showed mild mitral regurgitation, interatrial shunt (L-R 52%) and moderate pulmonary hypertension (Pp/Ps 0.48). The correction consisted of valvuloplasty of mitral valve and patch closure of ostium primum. The postoperative course was uneventful. The postoperative catheterization showed improved cardiac function.
