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.

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.

Background: Minimally invasive mitral valve surgery became an attractive option because of its cosmetic advantages over the conventional approach. The superiority of the minimally invasive approach regarding other aspects is still debatable. The aim of our study was to determine the potential benefits of minimally invasive mitral valve replacement with intraoperative video assistance over conventional surgery. Methods: This is a single-center prospective cohort study that included 60 patients with rheumatic heart disease who underwent mitral valve replacement. Patients were divided into two groups: group (A) included patients who had conventional sternotomy (n= 30), and group (B) included patients who had video-assisted minimally invasive mitral valve replacement (n= 30). Intraoperative and postoperative outcomes were compared between both groups. Results: Mortality occurred in one patient in the group (A). Cardiopulmonary bypass time was 118.93 ± 29.84 minutes vs. 64.73 ± 19.16 minutes in group B and A respectively (p< 0.001), and ischemic time was 102.27 ± 30.03 minutes vs. 53.67± 18.46 minutes in group B and A respectively (P < 0.001). Ventilation time was 2.77± 2.27 vs. 6.28 ± 4.48 hours in group B and A respectively (p< 0.001) and blood transfusion was 0.50 ± 0.63 vs. 2.83 ± 1.34 units in group B and A respectively (p< 0.001).  ICU stay was 1.73 ± 0.64 days in the group (B) vs. 4.47 ± 0.94 days in group A (p< 0.001). Postoperative bleeding was 353.33 ± 146.77 ml in the group (B) vs. 841.67 ± 302.03 ml in group A (p <0.001). No conversion to full sternotomy was reported in group B. In group (B), two cases (6.6%) required re-exploration for bleeding vs. four cases (13.2%) in group (A) (p=0.67). The hospital stay was 6.13 ± 1.59 days in the group (B) vs. 13.27 ± 7.62 days in group A (p< 0.001). Four cases (13.3%) developed mediastinitis in group A and in the group (B), there was one case of acute right lower limb embolic ischemia. Conclusion: Video-assisted minimally invasive mitral operations could be a safe alternative to conventional sternotomy with the potential of lesser morbidity and earlier hospital discharge.

Objective: Cox Maze procedure is an effective surgical treatment of atrial fibrillation and it is often performed concomitantly with mitral valve surgery. However, some patients still experience atrial tachyarrhythmia post-surgery, which adversely affects heart function as well as their quality of life. Method: We present the case of a 66-year-old female patient who underwent mitral valve replacement with a bio-prosthesis and Cox-Maze procedure; she was later admitted to our center after 14 months due to pneumonia and atrial tachycardia. An electrophysiology study/ intervention was performed. Result: We successfully determined the mechanism and ablated the atrial tachyarrhythmia. The sinus rhythm was restored and was maintained 3 months post-procedure, with amelioration of the left ventricular function. Conclusion: Electrophysiology study with electro-anatomy mapping can help to determine the mechanism of arrhythmia to guide successful ablation of post-operative arrhythmia

<p class="Abstract">This study is based on the findings of a single surgeon’s practice of mitral valve replacement of 167 patients from April 2005 to June 2017 who developed symptomatic mitral restenosis after closed or open mitral commisurotomy. Both clinical and color doppler echocardiographic data of peri-operative and six months follow-up period were evaluated and compared to assess the early outcome of the redo mitral valve surgery. With male-female ratio of 1: 2.2 and after a duration of 6 to 22 years symptom free interval between the redo procedures, the selected patients with mitral valve restenosis undergone valve replacement with either mechanical valve in 62% cases and also tissue valve in 38% cases. Particular emphasis was given to separate the adhered pericardium from the heart completely to ameliorate base to apex and global contraction of the heart. Besides favorable post-operative clinical outcome, the echocardiographic findings were also encouraging as there was statistically significant increase in the mitral valve area and ejection fraction with significant decrease in the left atrial diameter, pressure gradient across the mitral valve and pulmonary artery systolic pressure. Therefore, in case of inevitable mitral restenosis after closed or open commisurotomy, mitral valve replacement is a promising treatment modality.</p>

Abstract Background Ischemic papillary muscle rupture (PMR) is a catastrophic complication following acute myocardial infarction (AMI). We evaluated early outcomes of PMR by using data from the Japan Cardiovascular Surgery Database, a nationwide Japanese registry. Methods We retrospectively analyzed data from 196 patients diagnosed with PMR following AMI in Japan between January 2014 and December 2017. Risk factors for operative mortality and severe complications following mitral valve surgery were analyzed. Results The 30-day and hospital mortality rates were 20% and 26%, respectively. Chronic hemodialysis, abrupt rupture after AMI, resuscitation before surgery, and preoperative venoarterial extracorporeal membrane oxygenation were associated with mortality. Mitral valve replacement was chosen mainly (90%) for surgical correction of mitral regurgitation in these patients. There was no significant difference in short-term outcomes between mitral valve replacement versus mitral valve repair, despite non-matched characteristics in background between the treatment groups. Concomitant coronary artery bypass grafting had no impact on short-term outcomes. Conclusions Information derived from the nationwide database of patients with AMI-associated PMR show that PMR is a rare condition in the modern era. However, PMR is a severe disease with a mortality rate as high as 26%. The severity of the condition is associated with the risk for poor outcomes.

Redo mitral valve surgery is hazardous, hence we explored an alternative approach using a port-access system that avoids reentry. Between October 1997 and December 2000, 32 patients underwent mitral reoperation using the system. All patients had previous cardiac operations. This procedure consisted of a right anterolateral minithoracotomy and femorofemoral cannulation using special port-access instruments and endoaortic clamping in 24 patients or direct transthoracic sliding-rod aortic clamping in 8. The valve disease was of rheumatic etiology in 28 patients and degenerative in 4. The valve was replaced in 31 cases and a paravalvular leak after mitral valve replacement was closed in 1. In 2 cases, the tricuspid valve was repaired along with mitral valve replacement. Mean total operating time was 4.5 ± 1.2 hours, cardiopulmonary bypass time 162 ± 72 minutes, and aortic crossclamp time 62 ± 21 minutes. There was no mortality, and mean stay in the intensive care unit was 22 ± 7 hours and hospital stay 6.4 ± 1.2 days. Postoperative blood transfusion was required in 12 patients. In view of the favorable results, we recommend using the port-access system as a standard approach for mitral reoperation.

Abstract Left ventricular outflow tract (LVOT) obstruction (LVOTO) is a rare but recognized complication of mitral valve surgery. Concomitant factors can cause significant clinical deterioration which requires urgent intervention. We present the case of a female patient who underwent closed valvotomy at age 20 for mitral stenosis secondary to rheumatic heart disease. Seventeen years later, a re-stenosed valve prompted mitral valve replacement (MVR) with a Carbomedics mechanical prosthesis. 8 years later, she re-presented with increasing dyspnoea. On echocardiogram a frond-like structure was visible in the LVOT, the valve housing was protruding into the LVOT and she had marked septal hypertrophy. The LVOT gradient was 72 mmHg. This is a novel case of mechanical MVR associated LVOTO due to at least three discrete factors. This case demonstrates how multiple factors can amalgamate to result in significant clinical deterioration. Over an 8-year period, all three distinct factors contributed to the development of severe LVOTO.
