Abstract null null Background null Carcinoid heart disease (CHD) is a rare complication of hormonally active neuroendocrine tumors that often requires surgical intervention. There are limited data on cardiac implantable electronic device (CIED) implantation in patients with CHD. null null null Objectives null We evaluated the experience of CIED implantation in patients with CHD. null null null Methods null Patients with a diagnosis of CHD and a CIED procedure from January 1, 1995 through June 1,...

Abstract null null Objective null To investigate the incidence and natural history of degenerative thoracic aortic aneurysms (TAAs) and compare results between ascending (aTAAs) and descending TAAs (dTAAs). null null null Patients and Methods null This population-based cohort study used the Rochester Epidemiology Project database from January 1, 1995, through December 31, 2015. Patients were classified as the aTAA or dTAA group. null null null Results null Of 238 Olmsted County residents studied...

OBJECTIVE To evaluate outcomes of elective surgical management of tricuspid regurgitation (TR) in patients with transvenous right ventricular leads, and compare results between non-lead-induced and lead-induced TR patients. PATIENTS AND METHODS We studied patients with right ventricular leads who underwent tricuspid valve surgery from January 1, 1993, through December 31, 2015, and categorized them as non-lead-induced and lead-induced TR. Propensity score (PS) for the tendency to have lead-induc...

Abstract Objectives The phenomenon of systolic anterior motion (SAM) of the mitral valve (MV) was discovered 50 years ago, but to date only a few studies have identified risk factors for SAM following mitral repair. There are limited data on the necessity of surgical re-intervention on the MV once SAM is discovered by intraoperative transesophageal echocardiography (TEE). We sought to 1) identify predictors of SAM in a large cohort of consecutive patients, 2) assess the rate of early re-interven...

OBJECTIVES We investigated haemodynamics and clinical outcomes according to type of pulmonary hypertension (PH) in patients with constrictive pericarditis (CP). BACKGROUND As the prevalence of CP with concomitant myocardial disease (mixed CP) grows, PH is more commonly seen in patients with CP. However, haemodynamic and outcome data according to the presence or absence of PH are limited. METHODS 150 patients with surgically confirmed CP who underwent echocardiography and cardiac catheterisation ...

Abstract null null Objective null To determine the impact of sleep-disordered breathing (SDB) on survival in patients with hypertrophic cardiomyopathy (HCM) following septal myectomy. null null null Patients and Methods null Patients with obstructive HCM undergoing septal myectomy from 2007 to 2016 were reviewed. Those who had an overnight oximetry test within 6 months before myectomy were included in analysis. Oxygen desaturation index was examined continuously and also categorically (SDB [>5/h...

Abstract Background Hyponatremia is an unrecognized risk factor for adverse outcomes after cardiac surgery. We sought to study the prevalence of preoperative hyponatremia and its impact in short-term and long-term outcomes after cardiac surgery. Methods Patients who had CABG, valve, or CABG and valve procedures from 2000 to 2016 and available preoperative serum sodium within 30 days of the index procedure were included in the study. The effect of preoperative sodium on short and long-term outcom...

Limited data are available on long-term outcome after repair of partial atrioventricular septal defects (pAVSD) in adults. We sought to review our experience. Between January 1, 1957 and December 31, 2016, 179 adult patients [median age (IQR) 34 (18, 72) years] underwent primary repair of pAVSD. The most common associated defects were secundum atrial septal defect (n = 38) and ventricular septal defect (VSD) (n = 7). Left atrioventricular valve (LAVV) zone of apposition (ZOA) was complete in 47 ...

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...
