ObjectivesLeft atrial dissection (LatD) is a rare and heterogeneous condition affecting many cardiovascular areas. The present article, by the means of personal case report illustration and systemic review of different clinical management, is aimed to give to clinicians further knowledge on this controversial topic.BackgroundLatD is an exceedingly rare but potentially fatal complication of cardiac surgery or catheter‐based interventional procedures. Most of the cases are iatrogenic and its incidence is expected to grow due to an increase in the number of percutaneous coronary intervention and structural heart disease procedures. The management of this complication is controversial, and it may depend on related etiologies.MethodsWe have reported our single‐case experience and review of the scientific literature, focusing on the decision‐making process and the strategical approach by multimodality imaging techniques.ResultsOur case of LatD with initial hemodynamic instability was surgically treated. Conservative approach is often employed in literature despite the fact that conservative versus surgical approach is debatable, depending on clinical presentation, hemodynamic stability, multimodal imaging findings, and personal experience of the center.ConclusionsAccording to systematic literature review, a watchful‐waiting strategy supported by multimodality imaging could be a safe and effective management in stable LatD.
The free margin running suture (FMRS) is a novel technique for nonresection correction of degenerative mitral regurgitation. It was employed in 37 minimally invasive mitral repair cases. We performed a retrospective collection of in-hospital data and a clinical/echocardiographic follow-up. All patients were discharged with none or mild mitral regurgitation, except one who had mild-to-moderate (2+) regurgitation. At follow-up (average: 2.1 years), all patients were alive; there were no instances of recurrent regurgitation, one case of 2+ regurgitation, and no valve-related complications. Average mitral valve area, mean gradient, and coaptation length were 2.9 cm ±0.1, 3.5 mm Hg ±0.9, and 1.1 cm ±0.2.
Coronary stent implantation had been established as a highly effective revascularization technique in patients with occlusive coronary artery disease. Transcatheter closure of atrial septal defects is becoming a definite alternative to surgery in properly selected patients. During a 19-month period, 6 patients (50% women; mean age, 58 +/- 17 years; range, 32-73 years) of a consecutive series of 176 prospective multicenter registry patients undergoing transcatheter atrial septal defect closure were treated with sequential percutaneous coronary revascularization and Amplatzer septal occluder implantation. Indication for revascularization was stable angina in four patients and unstable angina in two. Indication for defect closure was significant left-to-right shunt with right ventricular enlargement. Defect diameter ranged from 13 to 20 mm by transesophageal echocardiography, and the stretched diameter measured 13 to 25 mm. Procedural success of both interventions was achieved in all cases without in-hospital complications. A total of seven stents were successfully implanted in five coronary vessels. No stent was used in one patient after successful PTCA. Immediate total closure of the defect was obtained in five patients. Trivial residual shunting, observed in one patient, disappeared at 24 hr. No adverse cardiac events, recurrence of anginal symptoms, or evidence of residual shunt were observed at clinical and echocardiographic follow-up, which ranged from 60 to 390 days (mean, 258 +/- 150 days). These results suggest that sequential transcatheter therapy of coronary artery disease and atrial septal defect is safe and efficacious in selected patients.
Echinococcal lesions rarely involve the heart; nonetheless, echinococcal cysts of the left ventricular myocardium often demand surgical treatment due to the risk of rupture and anaphylaxis. Herein, an echinococcal cyst of the anteroapical left ventricular wall was managed through small left anterior thoracotomy; repair was achieved under cardioplegic arrest (endoaortic balloon occlusion) with an uneventful course. We discuss the usefulness of such a less invasive approach for the depicted lesion (minimized manipulation of the heart and reduced surgical aggressiveness) and for other lesions involving the apical/lateral LV region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
