Direct closure of an asymptomatic right coronary sinus of Valsalva aneurysm
No full textA 52-year-old man was referred for evaluation of palpitation. Transthoracic echocardiography revealed an extracardiac aneurysm of the right coronary sinus of Valsalva, and normal anatomy of the aortic valve with no regurgitation. Three-dimensional computed tomography confirmed the aneurysm with a diameter of 21 × 13.7 mm arising from the right coronary sinus of Valsalva under the right coronary artery. Surgical repair was performed without changing the normal anatomy of the aortic valve, preserving the right coronary ostium. Intraoperative and postoperative echocardiography showed complete closure of the aneurysm with normal functioning of the aortic valve.

Vascular Complications following Isolated Limb Perfusion for Local Recurrence of Extremity Melanoma: A Case Report and Literature Review
Full text linkIntroduction. To evaluate the role of hyperthermic isolated limb perfusion (HILP) in arterial thrombosis following melanoma-soft tissue sarcoma chemotherapy. Report. Here is presented one case of iliac-common femoral artery subacute thrombosis and a review of the appropriate literature performed using a MEDLINE search. Acute/subacute arterial occlusion is one of the most feared vascular complications of HILP, located nearly always in the external iliac-femoral artery axis, being those vessels cannulated for perfusion. Conclusions. The small number of reported cases indicates either the rarity of this complication or unawareness of its existence. The true incidence of this complication is probably underreported
Coronary-coronary bypass: theoretical basis and techniques
No full textThe authors present their experience with coronary-coronary bypass grafting. This technique takes advantage of physiological position of the right coronary artery ostium. The filling of the graft and of the coronary circulation is assisted by several factors promoting the physiological diastolic coronary artery blood flow
Aneurysms of the coronary arteries: one case report
No full textTrue aneurysms of the coronary arteries are very uncommon. In our institution, from December 1982 to April 1987, in more than 2500 coronarographies, we observed only one case whose angiographic findings revealed a real fusiform aneurysm (at least 3 times the diameter of the original vessel) of the right coronary artery. The same patient exhibited a left anterior descending artery ectasia too, as we already noted in other cases not included in the present report. The other coronary arteries showed no associated lesions. Clinical findings included a previous myocardial inferior infarction and typical precordial effort pain with a basal and stress ECG showing non specific ST-T wave abnormalities. The patient underwent right coronary endoaneurysmectomy with interposition of a saphenous vein graft. Postoperative course was uneventful and 8 months after surgery the patient was asymptomatic, and basal and effort ECG showed no ischemic modification. Control angiogram revealed an optimal anatomical reconstruction with no further evolution of the left anterior descending artery dilatation. The distinction between vessel dilation and an aneurysm is discussed

No full textPartial anomalous pulmonary vein connection
No full textA 71-year-old female presented with increasing dyspnea and atrial fibrillation and was found to have severe tricuspid insufficiency, pulmonary hypertension, an intact atrial septum, and a partial anomalous pulmonary vein connection (PAPVC) between the left superior pulmonary vein (LSPV) and the left anomalous vein (LAV) (Fig. 1A, B). At the time of surgery, the patient underwent tricuspid valve ring annuloplasty, bipolar ablation, and an anastomosis of the LSPV to the left atrium (Fig. 1C, D). The patient has remained asymptomatic and in normal sinus rhythm six months after surgery.
