[Mobile multiple left chamber thrombi causing multiple embolism in the limbs requiring surgery].

The authors report on the case of a 35-year-old man with multiple risk factors, who was sent to cardiac examination in order to find the cause of microembolisms on his fingers of his hands and on his right leg. According to the history and the ECG the patient had suffered an anterior myocardial infarction at home two months before the embolisms which had not been detected at that time. Performing 2D echocardiography, wall motion abnormality indicating anterior myocardial infarction and several thrombi were found as the source of embolisms. One of the thrombi were highly mobile. During 7 week of anticoagulant therapy there was no new embolism but the thrombi did not show regression, therefore the patient was sent to the Hungarian Institute of Cardiology where successful thrombectomy and revascularisation were performed after transoesophageal echocardiography and coronarography. At two year follow-up after the surgery there was no new thrombus detected. In connection with the case the authors surveyed the literature of left ventricular thrombus formation following myocardial infarction.

[Prinzmetal angina pectoris causing diagnostic and therapeutic problems].

A 53 year old patient was hospitalized because of retrosternal oppression which was unrelated to effort and recurred in the early morning hours. An esophageal diverticulum and a hiatal hernia were found. The patient had complaints in spite of medical therapy and an operation was performed because of his oesophageal disorders. After operation the patient had the same pain. A cardiologist was asked, who suggested Prinzmetal variant angina. During arteriography coronary artery disease was found. Coronary bypass surgery was indicated and performed, after that procedure the patient was and remained free of any complaints. This observation reaffirmed Prinzmetal original statement "The key to the diagnosis ... is the taking of a painstaking history".

Ruptured aneurysms of the sinus of Valsalva.

From 1969 to 1989, 15 patients with an aneurysm of the sinus of Valsalva underwent operative correction. This represents 0.23% of 6515 cardiac operations with cardiopulmonary bypass during that time. There were 8 males and 7 females ranging in age from 15 to 54 years (mean 35.8 years). Symptoms of congestive heart failure, fatigue and palpitation were common. All patients underwent cardiac catheterization including aortography. Associated lesions included aortic valve regurgitation in 6 patients and a ventricular septal defect in 3 patients. The following connections occurred: right coronary sinus to right ventricle (8 patients), right coronary sinus to both right atrium and right ventricle (1 patient), and noncoronary sinus to right atrium (6 patients). The aneurysm was repaired via aortotomy or through the chamber into which it emptied. The aortic valve was replaced in 2 patients. There were no early or late postoperative deaths. Fourteen patients were in NYHA functional class I at late follow-up (range 0.5 to 20.5 years, mean 8.7 years). There have been no recurrences. Our experience supports the concept that early surgical intervention in patients with ruptured aneurysms of the sinus of Valsalva is justified.

Guidewire snap causing left main coronary occlusion during coronary angioplasty.

The case of a 34-year-old female patient is presented. During attempted left anterior descending coronary angioplasty, the exchange guidewire (0.018 inch, 300 cm) snapped and the distal 20 cm of the wire caused immediate thrombotic occlusion of both the left anterior descending and circumflex arteries. The resulting complication was treated by emergency bypass surgery.

The importance of endothelial cells in the course of vascular surgical interventions.

Aorto-coronary bypass made by implanting the patient's own saphenous vein may exhibit a tendency to early and late occlusion. This phenomenon is influenced by a number of factors including intraoperative damages of the graft. To determine preferable techniques for preserving vein integrity, various human graft preparation techniques were compared. Endothelial damage may occur during the preparation of the saphenous vein; the extent of damage depends on the preparation technique. In our studies the endothelium was best preserved by Rheomacrodex filling at 100 water cm pressure. Early occlusion seems to be best avoided in certain conditions using Gore-tex (polytetrafluoro-ethylene) prostheses due to the fact that the structure of Gore-tex simulates the normal endothelium covering of the luminal surface of the vessels and renders quick "re" endothelialization. This may reduce the hazard of early graft occlusion. In the present study experimental models and grafts implanted in humans were compared and results were tested by scanning electron microscopy.

Surgical treatment of left ventricular thrombi: two-dimensional echocardiographic diagnosis.

Two cases of successful surgical removal of left ventricular thrombi are presented. Two-dimensional echocardiography revealed in the first case multiple masses of thrombi in the dilated ventricle consistent with congestive cardiomyopathy and emergency surgery was performed for cerebral embolism. In the second case the thrombus was pedunculated and calcified, a probable sequel of a 17-year old myocardial infarction. The pertinent literature of echocardiographic and surgical aspects of left ventricular thrombi is reviewed.
