Dynamic subaortic obstruction: A disease of the mitral valve suitable for surgical repair?

SummaryWe describe an infant with complex congenital heart disease, including double orifice of the mitral valve associated with complex subaortic stenosis. Transthoracic and intraoperative transesophageal echocardiography were used to define three distinct anatomic abnormalities, all potentially contributing to the subaortic obstruction. Stepwise surgical repair with transesophageal echocardiographic monitoring of hemodynamic function ensured optimal initial surgical results. Overwhelming postoperative complications ensued, however, and the patient died. Postmortem findings are also presented.

SummaryAccessory atrioventricular valvar tissue is uncommon and, on occasion, has been identified as a cause of ventricular outflow obstruction. Accessory tricuspid valvar tissue has been reported to cause subpulmonary obstruction but infrequently has accessory tissue arising from the mitral valve been associated with obstruction. This paper reports two cases of subvalvar obstruction; the first in association with a ventricular septal defect causing subaortic obstruction and the other in association with congenitally corrected transposition and a ventricular septal defect, causing subpulmonary obstruction.

Objective Owing to the complex anatomy of the mitral valve, successful surgical repair of degenerative regurgitation remains a challenging procedure in cardiac surgery. Methods This paper aimed to report on our single-center experience with 20 patients who received an adjustable annuloplasty ring (Cardinal ring, ValtechCardio Ltd, Or Yehuda, Israel) as part of their mitral valve repair procedure. The device allows for intraoperative echocardiography-guided ring size adjustments under beating-heart conditions. Results All of the 20 patients left the operating room without any residual mitral regurgitation. There was no risk of systolic anterior movement (SAM) because of image-guided fine tuning of the ring before weaning the patient from bypass. Conclusions Further multicenter data are required to prove the concept of adjustable annuloplasty devices.
