41. Edge‐to‐edge tricuspid valve repair for severe tricuspid regurgitation 20 years after cardiac transplantation.

Abstract

Tricuspid valve regurgitation in orthotopic heart transplant recipients is common. Surgical corrections have been the mainstay of the treatment for diuretic‐refractory heart failure due to severe tricuspid regurgitation. However, post‐transplant patients inherently carry higher surgical risk owing to previous sternotomy and immunocompromised state. We report a case of successful percutaneous edge‐to‐edge tricuspid valve repair for severe tricuspid regurgitation after cardiac transplantation. A 27‐year‐old man with a history of idiopathic restrictive cardiomyopathy status after orthotopic heart transplant presented with severe right‐sided heart failure symptoms. A transthoracic echocardiogram showed bi‐atrial enlargement and moderate‐to‐severe tricuspid regurgitation, and an increase to the severe range with exercise. Percutaneous edge‐to‐edge tricuspid valve repair was performed. The patient's symptoms improved, and follow‐up echocardiogram showed mild tricuspid regurgitation. Percutaneous tricuspid valve repair can be considered as an alternative option to conventional surgery for symptomatic severe tricuspid regurgitation in orthotopic heart transplant recipients with suitable anatomy.

44. Percutaneous Coronary Intervention With Drug-Eluting Stent Versus Optimal Medical Therapy for Chronic Total Occlusion: Systematic Review and Meta-Analysis.

Abstract

The optimal treatment strategy for coronary chronic total occlusion (CTO) has not been well established. The benefit of percutaneous coronary intervention (PCI) was inferred mainly from observational studies comparing successful versus failed PCI without a control group receiving optimal medical therapy (OMT). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies comparing PCI using drug-eluting stent (DES) versus OMT alone in patients with CTO. Eight studies were identified: 3 RCTs and 5 observational studies. Among a total of 4784 included patients, 2461 patients underwent PCI and 2323 patients received OMT. There was a significant association between PCI and lower cardiac mortality (odds ratio = 0.62; 95% confidence interval 0.42-0.93; P =.02). There was no significant difference between PCI and OMT regarding major adverse cardiac events, recurrent myocardial infarction (MI), repeat revascularization, or stroke. In the RCT subset (1399 patients), there was no significant difference between PCI and OMT regarding clinical outcomes. Compared with OMT alone, PCI with DES for CTO was associated with lower cardiac mortality, mainly driven by observational studies, without significant difference in recurrent MI or repeated revascularization. Further RCTs are needed to investigate the role of PCI for management of patients with CTO. [ABSTRACT FROM AUTHOR]

47. Clinical Outcome of Takotsubo Cardiomyopathy Diagnosed With or Without Coronary Angiography.

Abstract

Takotsubo cardiomyopathy (TC) is definitively diagnosed following the exclusion of acute coronary syndrome. We aimed to examine the rate of coronary angiography in patients diagnosed with TC and also the outcome of patients with TC diagnosed with or without coronary angiography. We analyzed the National Inpatient Sample database from 2010 to 2014 and identified patients hospitalized with a primary diagnosis of TC. We compared in-hospital mortality between patients who underwent coronary angiography and those who did not. We also evaluated the association between coronary angiography and in-hospital mortality using a propensity score–adjusted multivariable analysis. Among 22 818 patients diagnosed with TC, 87.4% underwent coronary angiography and 12.6% did not. Patients who did not undergo coronary angiography had a higher in-hospital mortality than those who did (3.0% vs 0.9%; P < .001). Increased mortality in patients who did not undergo coronary angiogram was observed in both male (8.0% vs 2.8%; P = .03) and female patients (2.6% vs 0.7%; P < .001) and in patients 61 to 80 years old and ≥81 years old, but not in patients ≤60 years old. Multivariable analysis demonstrated that the lack of coronary angiography was independently associated with higher in-hospital mortality (adjusted odds ratio: 2.92; 95% confidence interval: 1.52-5.65; P = .001).
