Intraoperative cryoablation of atrial fibrillation with the old-fashioned cryode tips: a simple, effective, and inexpensive method.
2006
Nowadays atrial fibrillation is usually treated simultaneously with cardiac procedures, and new cryo-systems have been developed for performing easier and faster intraoperative ablation. However, the old cryode designs can still be useful in surgical practice and represent a more cost-effective method. In this article we present a technique using old-fashioned cryodes for intraoperative treatment of atrial fibrillation and comment on its advantages and limitations.
Training Cardiac Surgeons: Safety and Requirements.
2021
To analyze whether cardiac surgical residents can perform their first surgeries without compromising patients' safety or outcomes, by comparing their performance and results to those of senior surgeons. All documented CABGs conducted between 2002 and 2020 were included. Surgeries were divided according to the experience level of the main surgeon (defined by the number of CABG conducted by him/her) using the following thresholds: 1000; 150; 80 and 35. This resulted in 5 groups: senior surgeons (the reference group); attending surgeons; fellow surgeons; advanced residents and new residents. Primary endpoint was 30 day mortality. Secondary endpoints included a list of intra and post-operative …
Reducing Rebreathing During Noninvasive Ventilation: Bias Flow or No Bias Flow?
2019
To the Editor : We read with interest the article by Signori et al[1][1] that evaluated CO2 rebreathing during noninvasive ventilation (NIV) via a full face mask connected to a double-limb ventilation circuit with 2 different configurations: (1) a single mask connector directly attached to the Y-
Mid-regional pro-atrial natriuretic peptide and copeptin as indicators of disease severity and therapy response in CTEPH
2020
Background Chronic thromboembolic pulmonary hypertension (CTEPH) leads to right heart failure. Pulmonary endarterectomy (PEA) or balloon pulmonary angioplasty (BPA) restore pulmonary haemodynamics and allow cardiac recovery. This study examined the relationship of copeptin and mid-regional pro-atrial natriuretic peptide (MR-proANP) levels to disease severity and therapy response. Methods This observational cohort study included 125 patients (55 PEA/70 BPA) who underwent treatment and completed a 6-/12-month follow-up. Biomarkers, measured at baseline, prior to every BPA and at follow-up, were compared to 1) severe disease at baseline (right atrial pressure (RAP) ≥8 mmHg and cardiac index ≤2…
A New Technical Approach For Retrograde Administration of Cardioplegic Solutions
1989
Myocardial protection via the coronary sinus is now currently used by several groups. Although it has generally provided satisfactory results, some of its problems are still not completely resolved. We present a new technique of cardioplegia delivery through the coronary sinus with a Pezzer catheter inserted into it and secured in place by a purse string suture. We believe that this method is safer and more reliable than others.
Successful surgery of neuroendocrine carcinoma infiltrating right ventricle and pulmonary artery.
2020
We present the clinical case of a 60-year-old woman complained of dyspnea on exertion. Echocardiogram showed a giant mass in the right ventricle (RV) with obstruction to the outflow tract. Thorax computed tomography confirmed a mass of greater than 60 mm infiltrating RV and causing severe stenosis in the pulmonary artery, with severe pericardial effusion. Cardiac surgery was performed for tumor resection and pulmonary root replacement with a biological valved conduit. Histological analysis diagnosed a poorly differentiated large-cell neuroendocrine carcinoma. The patient had no immediate postoperative complications and has completed radiotherapy at a 9-month follow-up.
Prediction of mortality rate in acute type A dissection: the German Registry for Acute Type A Aortic Dissection score.
2020
Abstract OBJECTIVES The goal was to develop a scoring system to predict the 30-day mortality rate for patients undergoing surgery for acute type A aortic dissection on the basis of the German Registry for Acute Type A Aortic Dissection (GERAADA) data set and to provide a Web-based application for standard use. METHODS A total of 2537 patients enrolled in GERAADA who underwent surgery between 2006 and 2015 were analysed. Variable selection was performed using the R-package FAMoS. The robustness of the results was confirmed via the bootstrap procedure. The coefficients of the final model were used to calculate the risk score in a Web-based application. RESULTS Age [odds ratio (OR) 1.018, 95% …
Exercise ECG Testing and Stress Cardiac Magnetic Resonance for Risk Prediction in Patients With Chronic Coronary Syndrome
2021
Vasodilator stress cardiac magnetic resonance (VS-CMR) has become crucial in the workup of patients with known or suspected chronic coronary syndrome (CCS). Whether traditional exercise ECG testing (ExECG) contributes prognostic information beyond VS-CMR is unclear.We retrospectively included 288 patients with known or suspected CCS who had undergone ExECG and subsequent VS-CMR in our institution. Clinical, ExECG, and VS-CMR variables were recorded. We defined the serious adverse events (SAE) as a combined endpoint of acute coronary syndrome, admission for heart failure, or all-cause death.During a mean follow-up of 4.2 ± 2.15 yr, we registered 27 SAE (15 admissions for acute coronary syndr…

Device Therapy for Rate Control: Pacing, Resynchronisation and AV Node Ablation
2017
Atrioventricular node ablation (AVNA) is generally reserved for patients whose atrial fibrillation (AF) is refractory all other therapeutic options, since the recipients will often become pacemaker dependent. In such patients, this approach may prove particularly useful, especially if a tachycardia-induced cardiomyopathy is suspected. Historically, an "ablate and pace" approach has involved AVNA and right ventricular pacing, with or without an atrial lead. There is also an evolving role for atrioventricular node ablation in patients with AF who require cardiac resynchronisation therapy for treatment of systolic heart failure. A mortality benefit over pharmacotherapy has been demonstrated in…
