Outcome of surgical closure of doubly committed subarterial ventricular septal defect

BACKGROUND: From 1986 to March 1997, 128 patients diagnosed to have doubly committed subarterial ventricular septal defects (VSD) were reviewed. Patients with aortic regurgitation (AR), and aortic valve (AV) deformity or a large left-to-right shunt across the VSD were offered operation. Forty-five patients (27 men, 18 women) agreed to surgical closure of their VSDs. METHODS: Thirty-eight patients had VSD closure alone, and 7 had an additional AV repair. Other associated defects corrected at operation were closure of atrial septal defects, closure of other ventricular septal defects, ligation of patent ductus arteriosus, and repair of ruptured sinus Valsalva aneurysm. RESULTS: There was no mortality nor major morbidity associated with operation. In the 26 patients with AR and AV deformity preoperatively, valve repair was performed in 6 patients. The condition of AR improved in 4, and remained unchanged in 22 patients. In the 10 patients with a deformity of the AV and no AR preoperatively, the condition remained unchanged in 5 patients, from whom 1 had valve operation, but progressed in 5 patients postoperatively at a mean follow-up of 6.4 years. In 9 patients with no deformity of the AV and no AR preoperatively, there was no postoperative AR and no progress of valve deformity. CONCLUSIONS: Excellent results were obtained with VSD closure and AV repair. Surgical closure of VSD, if performed before the onset of AV deformity, may prevent progressive AR. If AV repair is performed after the onset of AV deformity, progressive AR may not always be prevented.     

Repair of partial atrioventricular septal defect through a minimal right vertical infra-axillary thoracotomy

OBJECTIVE: To report a new minimally invasive and cosmetic approach for partial atrioventricular septal defect (PAVSD) repair. METHODS: From November 1997 to January 2000, six patients with a mean age of 19.2 +/- 7.7 years underwent minimal right vertical infra-axillary thoracotomy for PAVSD repair. Left atrioventricular (AV) valve regurgitation was assessed on the beating heart before and after valvuloplasty. Commissuroplasty of the left AV valve and atrial septum repair were done in all patients. RESULTS: There were no operative or late mortality, and no morbidity directly related to the thoracotomy approach. The average length of the incision was 8.3 +/- 131 cm. The arrest times averaged 32.8 +/- 8.3 minutes, and the cardiopulmonary bypass times averaged 66.0 +/- 9.0 minutes. One patient had a mild to moderate left AV valve regurgitation postoperatively. All patients were free of symptoms during the follow-up. CONCLUSION: The minimal right vertical infra-axillary thoracotomy is a safer, more cosmetic and less invasive approach than median sternotomy for the repair of PAVSD.     

The long-term outcome of a surgical repair of sinus of valsalva aneurysm

BACKGROUND: In order to clarify the long-term outcome after surgical repair of a sinus of Valsalva aneurysm, we retrospectively assessed the operative results for patients treated in our institute. METHODS: The subjects were 27 patients who had undergone an operation between 1958 and 1996. For associated aortic regurgitation (AR) aortic valve repair was performed in 13 patients, 12 of whom had a ventricular septal defect (VSD); and an aortic valve replacement was performed in 3 patients, 1 of whom had a VSD. RESULTS: Five of the 13 patients who had aortic valve repair needed aortic valve replacement because AR developed after a period of between 7 and 13 years; those cases were complicated by VSD. Another 2 patients with mild AR also complicated by VSD are currently under observation. CONCLUSIONS: Although the postoperative outcome of the aortic valve repairs was good, cases that were complicated by VSD plus associated AR tended to develop AR later after surgery. Therefore, careful observation of the postoperative course is necessary.     

Repair of partial atrioventricular septal defect through a minimal right vertical infra-axillary thoracotomy

OBJECTIVE: To report a new minimally invasive and cosmetic approach for partial atrioventricular septal defect (PAVSD) repair. METHODS: From November 1997 to January 2000, six patients with a mean age of 19.2 +/- 7.7 years underwent minimal right vertical infra-axillary thoracotomy (VIAT) for PAVSD repair. Left atrioventricular (AV) valve regurgitation was tested on the beating heart before and after valvuloplasty. Commissuroplasty of the left AV valve and atrial septum repair were done in all patients. RESULTS: There was no operative or late mortality, and no morbidity directly related to the thoracotomy approach. The average length of the incision was 8.3 +/- 1.3 cm. The arrest times averaged 32.8 +/- 8.3 minutes, and the cardiopulmonary bypass times averaged 66.0 +/- 9.0 minutes. One patient had mild-to-moderate left AV valve regurgitation postoperatively. All patients were free of symptoms during follow-up. CONCLUSION: Minimal right VIAT is a safe, more cosmetic, and less invasive approach than median sternotomy for the repair of PAVSD.     

Repair of ventricular septal defect in adults

To evaluate the outcome of ventricular septal defect (VSD) with long duration of haemodynamic derangement, a retrospective study was made of 42 consecutive patients who underwent closure of VSD as adults (age range 15-48, mean 27 years). The mean systolic pulmonary arterial pressure was 53 mmHg, mean pulmonary vascular resistance 2.5 Wood units and mean pulmonary/systemic flow ratio 2.4. VSD was complicated by aortic regurgitation in 12 cases, mitral regurgitation in 4, and sinus of Valsalva fistula in 6 cases. There were 15 supracristal, 24 infracristal and 3 muscular VSDs. In addition to VSD closure, surgery included aortic valve replacement (7 cases), mitral valve replacement (2), valve repair by suture (7) and repair of Valsalva sinus fistula (6 cases). Two patients died in the early postoperative period and two during follow-up (1-10, mean 4.5 years). The early and the late mortality were related to large infracristal VSD, pulmonary hypertension and irreversible pulmonary vascular changes which could not be anticipated on the basis of high calculated shunt flow at preoperative catheterization. No patient with supracristal VSD died. Recurrent VSD was diagnosed in five patients, three of whom needed reoperation and recovered uneventfully. Reduction of heart size and improved exercise tolerance were the most pertinent follow-up findings. The results suggest that large supracristal VSD with aortic valve involvement can be successfully closed in adults, but that the prospect for large infracristal VSD is less favourable if correction is postponed until adulthood.
