Syndrome of ventricular septal defect and aortic regurgitation - A 22-year review of its management

Abstract Introduction: The presence of aortic regurgitation (AR) in the setting of ventricular septal defect (VSD) has always been a management challenge. Methods: This is a retrospective study looking at patients who underwent VSD closure with or without aortic valve intervention between January 1st, 1992 and December 31st, 2014 at the Institute Jantung Negara. This study looked at all cases of VSD and AR, where AR was classified as mild, moderate, and severe, the intervention done in each of this grade, and the durability of that intervention. The interventions were classified as no intervention (NI), aortic valve repair (AVr), and aortic valve replacement (AVR). Results: A total of 261 patients were recruited into this study. Based on the various grades of AR, 105 patients had intervention to their aortic valve during VSD closure. The rest 156 had NI. All patients were followed up for a mean time of 13.9±3.5 years. Overall freedom from reoperation at 15 years was 82.6% for AVr. Various factors were investigated to decide on intervening on the aortic valve during VSD closure. Among those that were statistically significant were the grade of AR, size of VSD, age at intervention, and number of cusp prolapse. Conclusion: We can conclude from our study that all moderate and severe AR with small VSD in older patients with more than one cusp prolapse will need intervention to their aortic valve during the closure of VSD.

Ventricular septal defect with aortic regurgitation: a hemodynamic and angiographic profile in Indian subjects.

The records of 362 patients of Ventricular Septal Defect (VSD) were analysed to find out the incidence of aortic regurgitation (AR) and their hemodynamic and angiographic features. Thirty-seven patients (10.2%) were found to have AR, whose mean age was 13.4 years (range: 2-45) and male to female ratio was 5:1. Of the 37 cases 31 (84%) had infracristal and 6 (16%) had supracristal VSD. In 31 patients with infracristal VSD the prolapsing cusp was Right Coronary Cusp (RCC) in 14 (48%), Noncoronary Cusp (NCC) in 12 (41%) and both RCC and NCC in 3 (11%). Of the 6 patients with supracristal VSD the prolapsing cusp was RCC in 5 (83%) and NCC in 1 (17%). In two patients the AR was due to bicuspid aortic valve. The pulmonary artery pressure was normal in 26 of 37 (70.2%) patients and the left to right shunt was 1.5:1 or less in 23 of 37 (62%) patients. Nineteen of the 37 patients (51.3%) had grade I or II AR and the remaining 18 (48.7%) had grade III or IV AR. There was no relationship between the severity of AR and the location of the VSD. In conclusion, in this series, the incidence of VSD+AR is relatively higher and that of supracristal VSD is lower. In majority of patients the left to right shunt is small and pulmonary artery pressure within normal limits. The prolapse of RCC is more common in supracristal VSD and there is no relation between the severity of AR and the location of the VSD.

Prevalência de prolapso valvar tricúspide e aórtico em portadores de prolapso valvar mitral / Prevalence of tricuspid and aortic valve prolapse in patients with mitral valve prolapse

Foram estudados, através da ecocardiografia bidimensional, 30 pacientes portadores de prolapso da valva mitral, sendo 15 do sexo feminino e 15 masculino, com idade média de 33,3 anos, com o objetivo de observar a prevalência de concomitante prolapso valvar tricúspide e aórtico. O prolapso da valva tricúspide foi obsrvado em 43,3% dos pacientes (13/30 anos, sendo que o folheto anterior e septal estava acometido em 92,3% e o posterior em 15,3% dos casos. A prevalência de prolapso da valva aórtica foi de 10% dos casos (3/30), estando ambos os folhetos avaliados - coronariano direito e näo coronariano - acometidos. Todos os pacientes com prolapso valvar aórtico apresentavam acometimento dos dois folhetos mitrais e de, no mínimo, dois folhetos tricuspídeos. Conclui-se que é comum o acometimento simultâneo das valvas tricúspide e aórtica em pacientes portadores de prolapso da valva mitral
