BACKGROUND Surgical myectomy eliminates symptoms in most patients with obstructive hypertrophic cardiomyopathy, but dyspnea and/or angina can recur in some. This study investigated clinical features associated with a lack of clinical improvement postoperatively. METHODS Between March 2007 and December 2012, 963 patients underwent transaortic septal myectomy at our clinic. Six hundred one patients received standardized follow-up questionnaires, which were answered by 409 (68.1%). We compared clin...

Background Previous studies suggest that patients with prior or current hematologic malignancy are at increased risk of intraoperative and postoperative complications when undergoing cardiac surgery. The aim of this review was to compare clinical outcomes of patients with a history of hematologic malignancy to those of similar patients with no known blood dyscrasia. Methods From January 1993 to June 2017, 37,839 patients underwent elective cardiac surgery at Mayo Clinic. We matched 612 patients ...

Abstract Purpose To determine the potential impact of referral bias on short- and long-term outcomes following septal myectomy for hypertrophic cardiomyopathy. Methods We reviewed 2303 adult patients who underwent transaortic septal myectomy for obstructive hypertrophic cardiomyopathy from January 1993 to April 2016. Patients were divided into 3 groups according to their permanent address: local (state) residents (n = 324), regional (surrounding 5 states) patients (n = 515), and national (outsid...

Abstract Objective To assess determinants of left atrial reverse remodeling after mitral valve (MV) repair and to evaluate the impact of preoperative left atrial volume on postoperative outcomes. Methods We reviewed records of 720 patients who underwent mitral valve repair from 09/2008-07/2015, and had preoperative measurement of left atrial volume index (LAVI). We analyzed the association of preoperative LAVI on early and late outcomes, and determined which baseline characteristics are associat...

Abstract Background Patients with obstructive hypertrophic cardiomyopathy (HCM) may have symptoms mimicking ischemic heart disease, including chest pain and shortness of breath. Some patients undergo coronary revascularization which may not lead to symptomatic improvement. This study assesses clinical presentations and outcomes of patients with previous coronary revascularization undergoing septal myectomy. Method From 08/1996 to 07/2017, 166 adult patients with obstructive HCM underwent septal ...

Abstract Severe coronary artery disease is associated with disproportionately increased risks of death in patients with hypertrophic cardiomyopathy. There is a paucity of data on the long-term effect of coronary revascularization at the time of myectomy. Between January 1, 1961, and October 31, 2017, 2913 adult patients underwent transaortic septal myectomy at Mayo Clinic. Concomitant coronary artery bypass grafting (CABG) was performed in 246 (8.4%). We compared baseline characteristics of pati...

Septal myectomy is the gold standard treatment option for patients with obstructive hypertrophic cardiomyopathy whose symptoms do not respond to medical therapy. This operation reliably relieves left ventricular outflow tract gradients, systolic anterior motion of the mitral valve, and associated mitral valve regurgitation. However, there remains controversy regarding the necessity of mitral valve intervention at the time of septal myectomy. While some clinicians advocate for concomitant mitral ...
