Coronary Bypass Grafting

Combined coronary bypass grafting and valve procedures for mitral valve regurgitation result in poor outcomes, but the impact of the etiology of valve regurgitation on operative and long-term outcomes is not well defined. A retrospective analysis of 468 patients who had combined coronary bypass grafting and valve operations for mitral regurgitation showed that 78% had valve repairs and 22% had replacements for ischemic (45%) or degenerative (55%) disease. Predictors of operative mortality were ischemic mitral regurgitation, failure to use the internal mammary artery for grafting, severe coronary disease, acute myocardial infarction, low ejection fraction, advanced heart failure, emergency operation, and mitral valve replacement. The 5-year survival rates for propensity-matched patients with ischemic or degenerative disease were similar (66%). Low ejection fraction (< 35%), advanced age (> 67 years), valve replacement surgery, residual mitral regurgitation, and severe coronary artery disease were predictors of poor long-term outcome. Although the operative outcomes of ischemic mitral regurgitation were poor compared to those of degenerative disease, the long-term survival was similar in both groups of propensity-matched patients. Left ventricular remodeling, an optimal valve procedure without residual mitral regurgitation, and left ventricular function are more important determinants of long-term outcome than the etiology of valve regurgitation.

Silent Myocardial Infarction

Acquired left ventricular pseudoaneurysm is a rare disorder that occurs after acute myocardial infarction. We present a 55 year-old male patient with a nonruptured pseudoaneurysm after acute MI presenting with severe mitral regurgitation. After resection of sac-like lesion, the defect was 5 cm diameter posterolaterally left ventricular. The aneursym was repaired with pericardium patch to maintain cardiac geometry that diminishes mitral regurgitation without intervention to mitral valve.

The Impact

Introduction: Presence of subclinical left ventricle (LV) dysfunction may influence outcomes after percutaneous mitral balloon valvotomy (PMBV), but cannot be detected by conventional echocardiography. Hypothesis: Preprocedure LV global longitudinal strain (GLS) by speckle tracking TTE detects subclinical LV dysfunction and predicts long-term outcome after successful PMVB. Methods: Consecutive patients undergoing PMBV between 2003-2011 who had comprehensive baseline TTE were included. Patients with suboptimal immediate results (repeat PMBV or mitral surgery within first 6 months) and those with suboptimal TTE strain were excluded. LV strain was analyzed with commercial software (Syngo VVI), and GLS averaged from 18 segments. The primary end point was all-cause mortality. Secondary end point was the composite of death and mitral valve reintervention. Results: Of 110 patients screened, 29 (26%) had unsuitable strain imaging, and 8 (7%) had poor immediate results, leaving 73 in the final cohort. Median follow-up was 3.7 years (interquartile range 1.3-7.2). There were 10 deaths (14%) and 25 late mitral valve interventions (34%). Univariate predictors of death were GLS, age, EF, stroke volume, pulmonary artery pressure, mitral valve area and coronary artery disease. In a multivariate Cox model, GLS was the strongest predictor of death after adjustment for age [HR=1.40 (1.09-1.84), P=0.008]. For the composite endpoint, GLS, mitral valve gradient, and invasively mean left atrial pressure were univariate predictors of death or reintervention. At multivariate analysis, GLS was the sole predictor of events [HR=1.17 (1.01-1.34), P=0.03]. Event-free survival is shown in figure. Intra and inter observer intra-class correlation for strain analysis was 0.87 (0.66-0.96) and 0.84 (0.53-0.95), respectively. Conclusions: GLS is a powerful predictor of long-term outcome after PMVB and appears to have an incremental prognostic value over traditional parameters.

Transcatheter Mitral Valve Repair

Abstract Background Left atrium (LA) dimension is a marker of disease severity and outcome in primary and secondary mitral regurgitation. In transcatheter mitral valve repair LA enlargement might additionally impact on device handling and technical success through an altered anatomy and atrial annular dilatation. Methods Data from the multicenter German transcatheter mitral valve intervention registry “TRAMI” were used to analyse the association of baseline LA diameter by tertiles and efficacy, safety and long-term clinical outcome in patients undergoing edge-to-edge repair with the MitraClip. Results In 520 of 843 patients prospectively enrolled in TRAMI baseline LA diameter were reported (median [interquartile range] LA diameter in tertiles: 44 [40–46] mm, 51 [48–53] mm and 60 [55–66] mm). Larger LA diameters were significantly associated with secondary etiology of mitral regurgitation, lower ejection fraction, larger left ventricle, male sex and atrial fibrillation (all p&lt;0.05). Technical success was not different across tertiles (96%, 95.4%, 98.4% respectively, p=0.43) as were major in-hospital cardiovascular and cerebral adverse events (mortality, myocardial infarction or stroke) (1.8%, 1.2% and 4.4%, p=0.11 across tertiles). However, 4-year mortality significantly increased with larger LA diameter (32.9%, 46.4% and 51.7% respectively, p&lt;0.01), as did hospitalization in survivors (60%, 67.6% and 78.9% respectively, p&lt;0.05). The association between LA diameter and all-cause mortality remained significant after multivariable adjustment including baseline left ventricular end-diastolic diameter. Conclusion LA enlargement is a strong and independent predictor of adverse long-term outcome in mitral regurgitation suggesting that timely transcatheter mitral valve repair may have the potential to modify outcome.

OBJECTIVES: Degenerative mitral valve disease is the most common indication for mitral valve repair in the Western world. The aim of this study was to study the long term outcome of mitral valve repair for degenerative mitral valve regurgitation in Iceland. MATERIAL AND METHODS: A retrospective study of 101 consecutive mitral valve repair patients (average age 57.7 years, 80.2% male) operated in Iceland 2004-2018 for degenerative mitral valve regurgitation. Long term survival and MACCE (major adverse cardiac and cerebrovascular event) free survival was estimated using the Kaplan-Meier method and compared to age and gender matched reference population. Median follow-up time was 83 months. RESULTS: On average there were 6,7 (range 1-14) mitral valve repairs performed annually with 99% of the patients receiving ring annuloplasty. A total of 82 (82,2%) underwent resection of the posterior leaflet and 64.4% recieved Gore-Tex®-chordae. Major early complications occured in 28.7% of cases, most commonly perioperative myocardial infarction (11.9%) and reoperation for bleeding (8.9%). Mortality within 30 days was 2%, the median duration of intensive care unit stay was one day and the median hospital length of stay was 8 days. One patient needed reoperation later for recurrent mitral regurgitation. Five and ten year MACCE-free survival was 91.1% (95%-CI: 85.3-97.2) and 81.0 (95%-CI: 71.6-91.6), respectively. Five year survival was 93.5% (95-CI: 88.6-98.7) and 10 year survival 85.3% (95%-CI: 76.6-94.9), which was not different from an age and gender matched reference population (p=0.135, log-rank test). CONCLUSION: Outcomes of mitral valve repair due to degenerative mitral regurgitation is good in Iceland and results are comparable to larger institutions overseas. Long term prognosis is generally good although early postoperative complications often occur
