Introduction : Despite the numerous benefits of resistance exercise (RE), stress caused by muscle contractions may cause transient disturbances in the cardiovascular system including arterial stiffness increasing the temporary risk of cardiovascular events. One physiological response which can influence this process but has received little attention from the scientific community is plasma volume (PV). Discussion : Recent reviews point to a complex interaction between autonomic modulation, central and peripheral adjustments triggered by a RE session. After the end of a moderate to high intensity RE session there may be a reduction in PV caused by its influx into the interstitial tissue and consequent decline in stroke volume and venous return. Moreover, there is an increase in sympathetic modulation, and a decrease in parasympathetic modulation. Arterial stiffness is one of the first signs of pathological changes in the arterial wall leading to an increased risk of cardiovascular events. The stiffening of the main arteries of the body can also be negatively affected by PV reduction. The PV reduction would lead to elevation of sympathetic nerve modulation, cardiac workload and reduction in cardiac perfusion. However, depending of the nature of the PV reduction contradictory results emerges and decrease in arterial stiffness was also reported. Conclusion : There is no agreement as to why PV reduction may affect arterial stiffness, and several questions regarding hydration status and RE influence remains to be addressed. Future studies should standardize water intake and control hydration status before and during experimental sessions utilizing simple measures of hydration status.

We present a case of resistant to medical treatment heart failure due to significant shunting through a secundum atrial septal defect by a 3-month old infant who underwent coarctectomy due to critical coarctation of the aorta at the age of 15 days. The tachydyspnea and failure to thrive persisted despite the successful resection of the coarctation and resolved very rapidly after subsequent operative closure of the atrial septal defect.

Premature supraventricular ectopic beats are common findings in ambulatory ECG monitoring. Blocked ectopic beats may occur if the premature beat coincides with the refractory period of the downstream conductive tissues. We report of an uncommon, symptomatic bigeminal rhythm which resulted in an abrupt decrease of the heart rate because of blocked P waves. The blocked P waves appeared uncommonly late in the cardiac cycle because of a very His-near activation site. For anatomic reasons treatment was difficult and the patient received a pacemaker.

Background: The number of cardiac operations is steadily increasing in industrialized countries, being Delirium one of the most frequent postoperative complications. Aortic Valve Replacement by mini-invasive surgery has reported to offer innumerable benefits over Complete Sternotomy, such as better esthetic, less surgical trauma, pain, blood and postoperative complications, a functional recovery and a shorter hospital stay. Objectives: To determine the frequency of Delirium and to identify its risk factors in patients undergoing mini-sternotomy (MS) versus full sternotomy (FS) isolated aortic valve replacement (AVR). Methods: An interdisciplinary, descriptive and retrospective study of 113 adults patients who underwent an Isolated Aortic Valve Replacement (AVR) with mini-sternotomy (MS) and full sternotomy (FS) was conducted. Variables related to delirium were characterized as being present before, during or after cardiac surgery. Results: Delirium occurred in 26 patients (23%). In the MS group, 12 patients (25%) had Delirium while 36 (75%) had no Delirium. In the FS group, 14 (21.5%) patients had Delirium whereas 51 did not have it (78.5%) and P: 0.66. Regarding to valve type among Delirium patients, 5 had a mechanical one while 21 patients with a biological valve. P: 0.02. Late extubation had 7 (6.2%) patients in the Delirium group versus 1 (9%) in the non-Delirium group. P: 0.001. Postoperative Hb analysis revealed an average of 9.2mg/dL and 9.8mg/dl for Delirium and non - Delirum patients respectively. P: 0.05. Renal disease was showed in 8 (7.1%) patients in the Delirium group versus 4 in the No delirium group (3.5%) with a P value of 0.001. No mortality event has been registered in any of the groups. Conclusion: MS has shown numerous advantages over conventional surgery before this study, nevertheless the risk of Delirium has not been previously assessed in this context. The risk factors and an increasing frequency of Delirium should be taking into account due to its high morbidity rate and significant cost of the health system.

We compared the efficacy and safety of radiofrequency with cryothermal energy in catheter ablation of patients with paroxysmal AF. The study included 24 consecutive patients with highly symptomatic paroxysmal AF (PAF) refractory to at least 1 class of antiarrhythmic drugs. Group I radiofrequency ablation and group II cryoballoon ablation (each group consists of 12 patients). Exclusion criteria: Patients <18 years, Structural heart disease (hypertrophic cardiomyopathy, left ventricular ejection fraction < 35%, significant valvular heart disease, LA size >50 mm), reversible causes of AF, intracardiac thrombus, inability to take oral anticoagulants, additional ablation lines other than cavotricuspid isthmus (CTI) and Repeat AF ablation. Transseptal puncture was performed under fluoroscopic guidance, one for the cryoballoon and two for the RF ablation.
