Since in the Valsalva graft the sinotubular junction height is predetermined, correct matching with native commissures height can be difficult. We propose a method by which it is possible to create a new sinotubular junction in Valsalva graft without altering its original configuration.

The port-access system has been described in detail elsewhere. It is based on femoral arterial and venous access for cardiopulmonary bypass (CPB) and on the adoption of a specially designed triple-lumen catheter described originally by Peters, and subsequently modified and developed in the definitive configuration called the endoaortic clamp.

Methods: From May 1989 to September 1991, 62 patients underwent mitral valve surgery (Group I), 19 underwent mitral valve surgery and DeVega tricuspid annuloplasty (Group II), 15 underwent mitral and aortic surgery (Group III), and 4 patients underwent mitral and aortic surgery and DeVega tricuspid annuloplasty (Group IV). Left atrial isolation was performed prolonging the usual left paraseptal atriotomy towards the left fibrous trigone anteriorly, and the postero-medial commissure posteriorly. The incision was conducted a few millimeters apart from the mitral valve annulus, and cryolesion were placed at the edges to ensure complete electrophysiological isolation of the left atrium. Results: Operative mortality accounted for 3 cases (3%). In 79 patients (81.4%) sinus rhythm recovered and persisted until discharge from the hospital. No differences were found between the groups (Group I: 80.7%; Group II: 68.5%; Group III 86.7%, Group IV 75% - p = N.S.). Three cases of late mortality (3.1%) were registered. long-term results showed persistence of SR in 71% of Group I, 61.2% of Group II, 85.8% of Group III, and 100% of Group IV. The unique risk factor for late recurrency of atrial fibrillation was found to be a duration of preoperative AF longer than 6 months. Conclusions: Due to the high success rate in recovering the sinus rhythm, we suggest left atrial isolation in patients with chronic atrial fibrillation undergoing valvular surgery.

Clinical and coronarographic characteristics and surgical techniques are presented. Eighteen cases were complicated by peri-operative myocardial infarction. Follow-up data, were available for 91% of the discharged patients, ranged between 5 and 33 months (mean 17,6). Two hundred and sixty-one patients were asymptomatic, 66 had improved clinical conditions, but angina was still present; 25 were unchanged while 5 had worsened. There were seven late deaths; 6 due to cardiac disease and 1 to a mesothelioma.

The authors analyse the results of operations in ectopic atrial tachycardias, the Wolff-Parkinson-White syndrome, modal re-entry tachycardias, and atrial fibrillation . The last-named is of most interest because the authors possess experience in a new operation for isolation of the internodal tracts. In all conditions the authors obtained convincing evidence on the efficacy of modern surgical treatment in supraventricular tachycardias.

The four cases in the ascending aorta presented a different aetiology: a) aneurysm on aortic stenosis (case 1); b) atheromatous aneurysm (case 2); c) aortic dissection (case 5); d) aneurysm due to dystrophy of the media in a patient with Marfan's disease (case 6). 3 tubular prosthetic substitutions of the ascending aorta were made (with a valvular substitution and commissural relocation associated with right aorto-coronary venous by-pass) and one plastic intervention on the aorta with valvular substitution. The aneurysms of the descending thoracic aorta presented traumatic aetiology and were treated with resection-dacron graft, using femoral artero-venous partial CEC.

Coronary artery bypass grafting (CABG) is generally accepted as the treatment of choice in these patients and randomized studies of large series have shown a significantly better prognosis for the operated patients, with 88% or 86% survival at 4 years [5, 7]. The data obtained from our experience with 155 consecutive cases of LMCAD treated by CABG form the basis of this report.
