Twenty-year experience of aortic valve reimplantation using the Valsalva graft.

Objectives: Over the past 20 years, valve-sparing aortic root replacement has aroused increasing interest because of a progressive attitude towards the preservation of natural tissue. Aortic reimplantation is the most used technique to spare the valve, allowing simultaneously aortic root replacement and aortic annular stabilization. The reimplantation into a graft with sinuses guarantees an optimal anatomic and functional reconstruction with established good results at 15 years.

Micro-Invasive 3D Endoscopic Mitral Valve Surgery.

Since its introduction in 1995, minimally invasive mitral valve surgery (MIMVS) has been shown to be a valid alternative to conventional sternotomy and several studies have reported excellent clinical outcomes. While MIMVS is now a commonly performed procedure, it is still difficult to standardize. We proprose here a "road to safer surgery", and offer some tips and tricks that could be useful in its learning and performance, and may help surgeons minimize the risk of major complications.

Cardiac surgery practice during the COVID-19 outbreak: a multicentre national survey.

Objectives: Healthcare systems worldwide have been overburdened by the coronavirus disease 2019 (COVID-19) outbreak. Accordingly, hospitals had to implement strategies to profoundly reshape both non-COVID-19 medical care and surgical activities. Knowledge about the impact of the COVID-19 pandemic on cardiac surgery practice is pivotal.

Cardiac surgery practice during the COVID-19 outbreak: a regionwide survey.

Background: Health systems worldwide have been overburdened by the "COVID-19 surge". Consequently, strategies to remodulate non-COVID medical and surgical care had to be developed. Knowledge of the impact of COVID surge on cardiac surgery practice is mainstem.

Stand-Alone Thoracoscopic Left Atrial Appendage Closure in Nonvalvular Atrial Fibrillation Patients at High Bleeding Risk.

Objective: In nonvalvular atrial fibrillation (AF) patients at high bleeding risk, oral anticoagulants (OAC) may be contraindicated, and percutaneous left atrial appendage (LAA) closure has been advocated. However, following percutaneous procedure, either OAC or dual antiplatelet treatment is required. In this study, we present our experience in treating nonvalvular AF patients at high bleeding risk with thoracoscopic LAA closure with no subsequent antithrombotic therapy.

Biomechanical and neuroautonomic adaptation to acute blood volume displacement in ischemic dilated cardiomyopathy: the predictive value of the CD25 test.

We aimed to examine biomechanical and neuroautonomic adaptation to blood volume displacement induced by tilt test in patients with previous inferoapical/inferolateral (IA-IL) or basal/apical septal (BS-AS) myocardial infarction (MI). Twenty-four patients with heart failure (HF) and previous IA-IL MI and 30 patients with HF and previous BS-AS MI were enrolled. All patients underwent head-up tilt test, radionuclide ventricular function monitoring (VEST), sympathovagal balance evaluation, and chronotropic 25-dose isoproterenol infusion test (CD).

Prominent basal and middle strain longitudinal involvement in newly-diagnosed and never treated hypertensive patients without clear-cut hypertrophy.

Background: Left ventricular (LV) global longitudinal strain (GLS) can detect an early dysfunction in arterial hypertension. We investigated regional LV patterns of longitudinal strain (LS) and base-to-apex behaviour in newly diagnosed, never-treated hypertensive patients (HTN) without LV hypertrophy.

Methods: 180 HTN and 115 healthy controls underwent standard echocardiography, including regional LS and GLS assessment (in absolute values).

Long-Term Results of Aortic Root Surgery in Marfan Syndrome Patients: A Single-Center Experience.

Background And Aim Of The Study: The study aim was to compare long-term results of Marfan syndrome (MFS) patients affected by aortic root disease undergoing aortic root replacement with the Bentall or David operation.

Methods: Since 1994, a total of 59 patients has been followed at the authors' Marfan Center, having undergone either a Bentall operation (Bentall group, n = 30) or a David operation (David group, n = 29).

Results: No operative mortality was recorded.

Total Arch versus Hemiarch Replacement for Type A Acute Aortic Dissection: A Single-Center Experience.

We retrospectively evaluated early and intermediate outcomes of aortic arch surgery in patients with type A acute aortic dissection (AAD), investigating the effect of arch surgery extension on postoperative results. From January 2006 through July 2013, 201 patients with type A AAD underwent urgent corrective surgery at our institution. Of the 92 patients chosen for this study, 59 underwent hemiarch replacement (hemiarch group), and 33 underwent total arch replacement (total arch group) in conjunction with ascending aorta replacement.

Pectoralis Muscle Flap Repair Reduces Paradoxical Motion of the Chest Wall in Complex Sternal Wound Dehiscence.

Background: The aim of the study was to test the hypothesis that in patients with chronic complex sternum dehiscence, the use of muscle flap repair minimizes the occurrence of paradoxical motion of the chest wall (CWPM) when compared to sternal rewiring, eventually leading to better respiratory function and clinical outcomes during follow-up.

Methods: In a propensity score matching analysis, out of 94 patients who underwent sternal reconstruction, 20 patients were selected: 10 patients underwent sternal reconstruction with bilateral pectoralis muscle flaps (group 1) and 10 underwent sternal rewiring (group 2). Eligibility criteria included the presence of hemisternum diastases associated with multiple (≥3) bone fractures and radiologic evidence of synchronous chest wall motion (CWSM).

Valve Replacement with a Sutureless Aortic Prosthesis in a Patient with Concomitant Mitral Valve Disease and Severe Aortic Root Calcification.

Aortic valve replacement with concomitant mitral valve surgery in the presence of severe aortic root calcification is technically difficult, with long cardiopulmonary bypass and aortic cross-clamp times. We performed sutureless aortic valve replacement and mitral valve annuloplasty in a 68-year-old man who had severe aortic stenosis and moderate-to-severe mitral regurgitation. Intraoperatively, we found severe calcification of the aortic root.

Fate of Normally Functioning Bicuspid Aortic Valve in Patients Undergoing Ascending Aorta Surgery.

Background And Aim Of The Study: Bicuspid aortic valve (BAV), though normally functioning, is frequently associated with dilatation of the aortic root and ascending aorta. Optimal surgical treatment remains controversial. The study aim was to evaluate the fate of the normally functioning spared BAV at long-term follow up.

Cardiac surgery with extracorporeal circulation and concomitant malignancy: early and long-term results.

Aims: We retrospectively evaluated early and long-term results of cardiac surgery using extracorporeal circulation (ECC) in patients affected by malignancies and the potential influence of ECC on malignancy progression during follow-up.

Methods: Out of 7078 patients referred for cardiac surgery from January 2001 to December 2012, 241 consecutive patients (3.4%) (mean age 72 ± 8 years; men 170) had malignancy either known before or detected during hospital stay.

Simultaneous carotid artery stenting and heart surgery: expanded experience of hybrid surgical procedures.

Background: The aim of this study was to evaluate 10-year results of same-day hybrid revascularization of concomitant carotid artery disease by stenting (CAS) and coronary artery disease by coronary artery bypass grafting (CABG), later also applied to patients requiring CAS and other than coronary open heart cardiac surgery.

Methods: One hundred thirty-two consecutive patients (70 ± 8 years, 102 men) underwent same-day CAS and CABG (group 1, n = 97) or other cardiac surgical procedures (aortic ± mitral valve surgery ± ascending aorta replacement ± CABG; group 2, n = 35). In both groups aspirin (100 mg daily) was started 2 days before CAS and permanently continued; clopidogrel, 300 mg initially followed by 75 mg daily, was started 6 hours after surgery and discontinued 1 month later.

Genetic variants are not associated with outcome in patients with coronary artery disease and left ventricular dysfunction: results of the Genetic Substudy of the Surgical Treatment for Ischemic Heart Failure (STICH) trials.

Objectives And Background: We evaluated the ability of 23 genetic variants to provide prognostic information in patients enrolled in the Genetic Substudy of the Surgical Treatment for Ischemic Heart Failure (STICH) trials.

Methods: Patients assigned to STICH Hypothesis 1 were randomized to medical therapy with or without coronary artery bypass grafting (CABG). Those assigned to STICH Hypothesis 2 were randomized to CABG or CABG with left ventricular reconstruction.

18-Fluoro-2-deoxyglucose positron emission tomography-computed tomography: an additional tool in the diagnosis of prosthetic valve endocarditis.

Objectives: To evaluate the role of 18-fluoro-2-deoxyglucose positron emission tomography-computed tomography ((18)F-FDG-PET-CT) in the diagnosis of infectious endocarditis (IE).

Methods: We retrospectively examined 27 consecutive patients who were admitted to the Infectious Diseases Department of Tor Vergata University Hospital between 2009 and 2013 with a suspicion of IE. The final IE diagnosis was defined according to the modified Duke criteria, and the microbiological and diagnostic results were collected for each patient.

The fate at mid-term follow-up of the on-pump vs. off-pump coronary artery bypass grafting surgery.

Aims: To evaluate the fate of on-pump coronary artery bypass grafting (ON-pump CABG) vs. off-pump coronary artery bypass grafting (OP-CABG) surgery at mid-term follow-up.

Methods: From January 2008 to December 2010, 369 patients underwent surgical myocardial revascularization by means of OP-CABG techniques (n = 166) or with ON-pump CABG (n = 203).

Effect of genetic factors on the association between coronary artery disease and PTPN22 polymorphism.

PTPN22 has been previously found associated with coronary artery disease (CAD). In the present note we have studied the effect of p53 codon 72, acid phosphatse locus 1 (ACP1) and adenosine deaminase (ADA) genetic polymorphism on the strength of association between PTPN22 and CAD. We have studied 133 non diabetic subjects with CAD, 122 non diabetic cardiovascular patients without CAD and 269 healthy blood donors.

Aortopathy in Marfan syndrome: an update.

Marfan syndrome (MFS) is an inherited autosomal dominant multisystem disease caused by mutations in the FBN1 gene encoding fibrillin-1, an extracellular matrix glycoprotein widely distributed in mesenchymal-derived tissues that provide a scaffold for elastin deposition. MFS is characterized by variable clinical manifestations, including skeletal, ocular, and cardiovascular abnormalities; ascending aortic aneurysm with ensuing dissection and rupture is the main life-threatening cardiovascular manifestation of MFS. Histological aspects of MFS aortopathy include a medial degeneration from disarray and fragmentation of elastic fibers and accumulation of basophilic ground substance areas depleted of smooth muscle cells (SMCs).

Five-year clinical outcome and patency rate of device-dependent venous grafts after clampless OPCAB with PAS-port automated proximal anastomosis: the PAPA Study.
