Left circumflex artery injury occurring during mitral valve surgery treated successfully with percutaneous intervention in a high surgical and bleeding risk patient

ABSTRACT: Perioperative myocardial infarction is a complication of cardiac surgery, and the cause can be multifactorial. Injury of the left circumflex coronary artery has been described, particularly after mitral valve replacement. We present the case of a 72-year-old woman who underwent mitral valve replacement but developed a lesion in the proximal circumflex coronary artery related to partial mechanical kinking caused by a suture. The therapeutic options are surgical or percutaneous. In this patient, the percutaneous strategy was successful.

Learning objective

• Percutaneous coronary intervention is an option in cases involving kinking of the left circumflex coronary artery after mitral valve replacement. • If unable to cross the lesion with a workhorse guide wire, one alternative is to use wires with good support properties and avoid very high tip loads to reduce the risk of perforation. In patients at high risk of bleeding, use of a drug-eluting stent and short-duration dual antiplatelet therapy is recommended.

Left circumflex artery injury following surgical mitral valve replacement: a case report.

Project description:BackgroundMitral valve (MV) repair or replacement surgery is indicated for a variety of conditions. Although uncommon, damage to the left circumflex (LCx) coronary artery, which courses in close proximity to the MV annulus, is a devastating complication.Case summaryThis report describes the case of a 63-year-old woman following re-operative MV replacement. Shortly after being transferred to the surgical intensive care unit after MV replacement, her EKG was notable for persistent inferolateral ST-segment elevations and reciprocal ST-segment depressions. Emergency transthoracic echocardiogram revealed a reduced left ventricular ejection fraction of 35-40% and mid to distal lateral wall motion hypokinesis. She was emergently taken to the cardiac catheterization laboratory where coronary angiography demonstrated complete occlusion of her mid LCx artery. She underwent urgent percutaneous coronary intervention of the lesion and was started on dual antiplatelet treatment, anticoagulation for comorbid atrial fibrillation, as well as guideline directed medical therapy with improvement in her EKG changes and cardiac function.ConclusionPrompt diagnosis and recognition of LCx injury is crucial. Management involves immediate percutaneous recanalization or surgical coronary bypass grafting.

Phasic disappearance of left circumflex coronary artery from an early complication of mitral valve surgery.

Project description:LV pseudoaneurysm can be a late complication of mitral valve replacement. In our case, it was an early postoperative complication. This pseudoaneurysm was causing compression of LCX artery during systole, leading to presentation of NSTEMI two weeks after the surgery.

Mitral valve annulus and circumflex artery: In vivo study of anatomical zones.

Project description:ObjectiveTo provide, with the use of preoperative coronary computed tomography angiography, an in vivo anatomical characterization of the relationship between the circumflex artery and mitral valve annulus to identify different risk classes and to increase the surgical awareness of those anatomical relations.MethodsNinety-five (mean age: 64.2 ± 11.7) consecutive patients, initially referred for elective minimally invasive mitral valve surgery, underwent preoperative coronary computed tomography angiography. The distance between the circumflex artery and mitral annulus was assessed using 6 points designed on the posterior mitral annulus, starting from the anterolateral to the posteromedial commissure; this design created an ideal 5-zone system. High-risk anatomy was defined as a distance less than 3 mm between the circumflex artery and the mitral valve annulus.ResultsThe shortest distance between the circumflex artery and mitral valve annulus was observed at the area between the anterolateral commissure and the midpoint of P1 scallop, so-called zone 1 (5.49 ± 3.13 mm), whereas the longest distance occurred at zone 5 (12.03 ± 4.93). Twenty-four patients (25%) were identified with high-risk anatomy (mean distance 1.94 ± 0.8 mm). Left dominant and co-dominant hearts demonstrated a shorter circumflex artery-mitral valve annulus distance at all the zones. At multinomial logistic regression, the pattern of coronary dominance and the size of the circumflex artery were independent factors for high-risk anatomy.ConclusionsCoronary computed tomography angiography is a useful investigation to identify patients at risk of circumflex artery flow disturbance; for high-risk anatomy, this knowledge may enhance a safer operative technique.

Outcomes of transcatheter edge-to-edge mitral valve repair with percutaneous coronary intervention vs. surgical mitral valve repair with coronary artery bypass grafting.

Project description:AimsPatients with severe ischemic mitral regurgitation (IMR) may receive concurrent coronary artery bypass graft (CABG) with surgical mitral valve repair (SMVr) or percutaneous coronary stent implantation (PCI) with transcatheter edge-to-edge mitral valve repair (TMVr). However, there is no consensus on the management of severe IMR in this setting. We aimed to compare the outcomes of combined SMVr with CABG to concurrent TMVr with PCI among patients with IMR in the National Inpatient Sample (NIS) database.Methods and resultsThe National Inpatient Sample was queried for all patients diagnosed with IMR who underwent SMVr with CABG or TMVr with PCI during the years 2016-2018. Study outcomes included all-cause in-hospital mortality, periprocedural complications, and resources used. A total of 1,360 potentially eligible patients were included in the study. After 1:5 propensity score matching, 133 patients were classified in the SMVr + CABG group and 29 patients in the TMVr + PCI group. Adjusted mortality was higher in the TMVr + PCI group compared with the SMVr + CABG group (13.8% vs. 4.5%, P = 0.034). Perioperative complications were higher among patients who underwent SMVr + CABG including blood transfusions (29.3% vs. 6.9%, P = 0.01) and post-procedural cardiogenic shock (11.3% vs. 0%, P = 0.044). The cost of care was higher (USD$783548.80 vs. USD$331846.523, P = 0.001) and the length of stay was longer (17.9 vs. 15.44 days, P < 0.001) in the TMVr + PCI group. On multivariable analysis, age (OR, 1.039 [95% CI, 1.006-1.072]; P = 0.032), renal failure (OR, 3.465 [95% CI, 1.867-6.433]; P < 0.001), and liver disease (OR, 5.012 [95% CI, 2.578-9.686]; P < 0.001) were associated with in-hospital mortality.ConclusionTMVr + PCI was associated with higher resource use and in-hospital mortality but with improved perioperative complications compared with SMVr + CABG.

Project description:We describe a case of an adult patient with mitral valve regurgitation and the anomalous origin and course of the left circumflex coronary artery. Use of a ringless procedure or a microinvasive approach, such as transapical neochordae implantation, would have possibly avoided a life-threatening post-operative complication.
