Combined mechanical mitral valve replacement and transmitral myectomy for hypertrophic obstructive cardiomyopathy treatment: An experience of over 20 years.

Background: Although transaortic septal myectomy (TASM) is recognized as a standard procedure for treating hypertrophic obstructive cardiomyopathy (HOCM), occasionally the left ventricle (LV) intracavitary gradient remains postoperatively because of this technically demanding procedure. Mitral valve replacement (MVR) is sometimes chosen as an alternative option, but data on its long-term outcomes are lacking.

Methods And Results: Between 1991 and 2016, 29 patients [age, 14-82 (mean 58.

Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis Complicated by Sigmoid Septum.

Background: In patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS), a sigmoid septum, characterized by subaortic interventricular hypertrophy, often results in the need for new pacemaker implantation (PMI). In this study, we reviewed the feasibility and treatment efficacy of TAVR for AS in patients with a sigmoid septum.

Methods and results: Between 2011 and 2016, 48 patients (25.

Efficacy of regional saturation of oxygen monitor using near-infrared spectroscopy for lower limb ischemia during minimally invasive cardiac surgery.

Lower limb ischemia with an occlusive cannula is a potential complication of minimally invasive cardiac surgery (MICS). We evaluated intraoperative local oxygen supply-demand balance by monitoring regional saturation of oxygen (rSO) using near-infrared spectroscopy (NIRS), and analyzed the correlation between cannula size and fluctuation range of rSO. Fifty-four patients undergoing MICS surgery using femoral artery cannulation from April 2015 to August 2016 were enrolled.

Intracranial mycotic aneurysm is associated with cerebral bleeding post-valve surgery for infective endocarditis.

Objectives: The presence of cerebral haemorrhage (CH) preoperatively is a risk factor of in-hospital cerebrovascular complications post-valve surgery for acute infective endocarditis. However, factors related to cerebrovascular complications in the long term are poorly understood. We reviewed a series of these patients to investigate risk factors of in-hospital and long-term outcomes.

Functional mitral stenosis after mitral valve repair for Type II dysfunction: determinants and impacts on long-term outcome.

Objectives: This study was performed to analyse the impacts of functional mitral stenosis (MS) following mitral valve (MV) repair on late cardiac function and new onset of atrial fibrillation or survival.

Methods: We retrospectively reviewed 602 patients with mitral regurgitation who underwent MV repair for Type II dysfunction from 2001. Functional MS was diagnosed when the mean transmitral pressure gradient (MTPG) was ≥5 mmHg on postoperative echocardiography.

Late onset of atrial fibrillation in patients undergoing mitral valve repair for type II dysfunction.

Background: There are few reports regarding factors related to late-onset of atrial fibrillation (Af) after mitral valve repair, which can compromise long-term outcome. We analyzed the risk factors for late Af after mitral valve repair.

Methods And Results: Between 2001 and 2015, 318 patients (214 males; median, 57.

Transcatheter Aortic Valve Implantation for Degenerated 19-mm Aortic Bioprosthetic Valve.

Background: The valve-in-valve procedure, in which a transcatheter heart valve (THV) is implanted over a prosthetic valve, has been shown to be safe and therapeutically effective, depending on the size of the replacement valve.

Methods and results: We report 3 cases of successful valve-in-valve procedure to replace a degenerated 19-mm stented prosthetic aortic valve. Balloon-expanding THVs were implanted: 20-mm in the 1st case and 23-mm in the next 2.

Irrigation Device Successfully Tests Valve Competence During Minimally Invasive Mitral Valve Repair.

Minimally invasive mitral valve repair has become standard. We hypothesized that reproducible water testing with less air contaminations may help achieve successful repair and prevent air embolism. We used a long shaft irrigation device connected to an infuser pump to water test mitral valve repair in 104 consecutive patients with severe mitral regurgitation due to type II mitral valve dysfunction.

Long-Term Outcomes of Suture vs. Ring Tricuspid Annuloplasty for Functional Tricuspid Regurgitation.

Background: Whether there is a significant difference in the long-term surgical outcomes between suture annuloplasty and ring annuloplasty for the treatment of functional tricuspid regurgitation (TR) is still controversial. We compared the long-term outcomes of tricuspid annuloplasty (TAP) with and without an annuloplasty ring.

Methods and results: From January 1996 to December 2015, we consecutively enrolled 684 patients (mean age, 65.

889 days of support on hydrodynamic bearing rotation mode of the DuraHeart™ for bridge-to-heart transplantation.

A 49-year-old man with ischemic cardiomyopathy and tricuspid regurgitation underwent a DuraHeart implantation and tricuspid annuloplasty for bridge-to-heart transplantation. On postoperative day 393, the magnetic levitation system suddenly broke down, and the pump system went into hydrodynamic bearing rotation (HD) mode without causing relevant symptoms. The controller was exchanged with one that adapted to the HD mode.

Simultaneous transcatheter aortic valve implantation and off-pump coronary artery bypass grafting for Takayasu arteritis.

We report a patient who underwent simultaneous transcatheter aortic valve implantation and off-pump coronary artery bypass grafting for Takayasu arteritis with diffuse porcelain aorta. The patient was a 59-year-old female with severe aortic stenosis and regurgitation, as well as both coronary ostial stenosis and porcelain aorta. Bilateral internal thoracic arteries were unavailable due to Takayasu arteritis.

Reducing Prosthesis-Patient Mismatch With Edwards Magna Prosthesis for Aortic Valve Replacement.

Background: Prosthesis-patient mismatch (PPM) is associated with increased mid-term and long-term mortality rates after aortic valve replacement (AVR). This study aimed to evaluate the efficacy of the Carpentier-Edwards Perimount Magna and Magna Ease (CEPMs) aortic bioprostheses to reduce the incidence of PPM.

Methods and results: Altogether, 282 consecutive patients (113 women, mean age 69.

Comparison of Hemodynamic Performance and Clinical Results with EVAHEART Versus HeartMate II.

This study aimed to compare the hemodynamic performance and clinical results of the EVAHEART and HeartMate II left ventricular assist devices (LVADs). From 2007 to 2016, fourteen patients received EVAHEART and 28 received HeartMate II at our center. Early survival, driveline infection, and neurologic events were evaluated.

Long-term outcome of isolated off-pump coronary artery bypass grafting in patients with coronary artery disease and mild to moderate aortic stenosis.

Background: The best management strategy for patients with coronary disease and mild to moderate AS requires the clinician to consider the operative risks of isolated coronary artery bypass grafting (CABG) against the risks of untreated aortic stenosis (AS).

Methods: Between 2000 and 2014, isolated off-pump CABG (OPCAB) was performed in 2023 patients. Of these patients, 103 presented with mild or moderate AS (mean age 72.

Early Results of Simultaneous Transaortic Transcatheter Aortic Valve Implantation and Total Arterial Off-Pump Coronary Artery Revascularization in High-Risk Patients.

Background: Transcatheter aortic valve implantation (TAVI) has become an alternative procedure for treating aortic stenosis (AS) in patients with advanced age and severe comorbidities. Ischemic heart disease (IHD) is present with AS in 40-50% of patients with typical angina. Considering the high operative mortality and morbidity rates in these patients, hybrid TAVI and off-pump CABG (OPCAB) have become realistic treatment options.

[Emergency Redo Off-pump Coronary Artery Bypass Surgery after 22 Years in an Elderly; Report of a Case].

An 84-year-old male presented to our hospital with recurrent angina. He had undergone coronary artery bypass with a saphenous vein graft to the left anterior descending branch (LAD) 22 years before. Coronary angiography showed occulusion of the proximal LAD and significant stenosis of the saphenous vein graft.

[Off-pump Coronary Artery Bypass Surgery Following Aortic Root Replacement for Acute Type A Dissection ; Report of a Case].

A 45-year-old male presented to our hospital with worsening heart failure. Computed tomography coronary angiography revealed total occulusion of the proximal left anterior descending artery (LAD). The patient had a history of acute type A dissection,and had undergone aortic root replacement.
