Left ventricular pseudoaneurysm is a partial cardiac rupture, contained by the surrounding pericardium that maintains communication with the left ventricular lumen. Whereas most cases of left ventricular pseudoaneurysms are related to myocardial infarction (loss of myocardial integrity), only a handful are associated with valve surgery. We present a female patient, who was admitted for elective mitral valve replacement. After the implantation of the mechanical valve, we encountered a rupture of the atrioventricular groove. After 3 months, a left ventricular pseudoaneurysm was found and the patient was reoperated. The valve was explanted and the inspection of the annulus and previously implanted pericardial patch revealed a loosened stitch on the inferior (ventricular) side. The defect was reinforced with additional stitches and the valve was reimplanted. In conclusion, we report an unusual case with two serious complications after mitral valve replacement – atrioventricular groove rupture and left ventricular pseudoaneurysm.

Abstract Background Left ventricular rupture is the most feared complication in mitral valve surgery. Despite its low incidence, mortality rates can reach up to 75%. It usually presents on the operating room with a dissecting haematoma followed by massive bleeding after discontinuing cardiopulmomary bypass. However, cardiac rupture may be contained by adherent pericardium or scar tissue leading to chronic formation of a pseudoaneurysm (PSA). Case summary A 44-year-old man came to our institution with acute heart failure triggered by community-acquired pneumonia. He underwent mitral valve replacement with a mechanical prosthesis 7 years before and reported suffering from chronic worsening dyspnoea for 18 months. He underwent chest computed tomography scan and cardiac magnetic resonance imaging (CMRI), which showed two extensive left ventricular (LV) multilobulated PSAs. An operative approach was chosen and a tear was found on the posterior atrioventricular groove (AVG), communicating left ventricle with the PSA, which was closed with bovine pericardium patch. After weaning from cardiopulmonary bypass, he presented a diffuse life-threatening bleeding. The surgeons packed his chest with compresses before closing the sternum and he was operatively revised after 48 h. Post-operative CMRI showed that one of the PSAs remained connected with the LV. Despite of all, 1 year after hospital discharge, he remains asymptomatic without signs of heart failure. Discussion This case illustrates PSAs' potential to grow for a long period before causing symptoms, the complexity and risks of chronic AVG disruption surgery and the importance of careful annular manipulation and debridement as preventive measures in mitral valve surgery.

Background: Mitral valve replacement (MVR) is the only option for infants with severe mitral valve disease that is not reparable; however, previously reported outcomes are not always favorable. Our institution has followed a tailored approach to sizing and positioning of mechanical valve prostheses in infants requiring MVR in order to obtain optimal outcomes. Methods: Outcomes for 22 infants ≤10 kg who have undergone MVR in Sydney, Australia, from 1998 to 2016, were analyzed. Patients were at a mean age of 6.8 ± 4.1 months (range: 0.8-13.2 months) and a mean weight of 5.4 ± 1.8 kg at the time of MVR. Most patients (81.8%) had undergone at least one previous cardiac surgical procedure prior to MVR, and 36.4% had undergone two previous procedures. Several surgical techniques were used to implant mechanical bileaflet prostheses. Results: All patients received bileaflet mechanical prostheses, with 12 receiving mitral prostheses and 10 receiving inverted aortic prostheses. Surgical technique varied between patients with valves implanted intra-annularly (n = 6), supra-annularly (n = 11), or supra-annularly with a tilt (n = 5). After a mean follow-up period of 6.2 ± 4.4 years, the survival rate was 100%. Six (27.3%) patients underwent redo MVR a mean of 102.2 ± 10.7 months after initial MVR. Four (18.2%) patients required surgical reintervention for development of left ventricular outflow tract obstruction and three (13.6%) patients required permanent pacemaker placement during long-term follow-up. Conclusions: The tailored surgical strategy utilized for MVR in infants at our institution has resulted in reliable valve function and excellent survival. Although redo is inevitable due to somatic growth, the bileaflet mechanical prostheses used displayed appropriate durability.
