Technical Feasibility Does Not Guarantee Clinical Improvement: A Word of Caution for Valve-in-Valve Procedures in Small Surgical Prosthesis

Marie-Elisabeth Stelzmueller, Bruno Mora, Guenther Laufer and Wilfried Wisser

Article Type: Case Report | First Published: March 13, 2021

The reoperation of old and frail patients with small tissue valves is a still challenging topic in cardiac surgery. An 85-years-old patient who underwent an aortic valve replacement (AVR) with a Mitroflow 21 mm and single coronary bypass operation 6 years ago, presented again dyspnea NYHA II-III. The echo showed a restenosis of the tissue valve and a mean gradient of 40 mmHg. Because of age, frailty and calculated perioperative risk, the patient was evaluated for a transcatheter valve-in-valve i...

Complete Heart Block in a Patient with COVID-19

Ricardo J Villasmil, MD, Christian J Lorenzo, MD, Qassem K Abdelal, MD, Jorge I Conte, MD, Natalia Lattanzio, MD, Wilhelmine Wiese-Rometsch, MD and Henry G Cheng, MD

Article Type: Case Report | First Published: March 31, 2021

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been reported to cause cardiac complications including myocarditis, acute myocardial infarction (AMI) and various tachyarrhythmias. We present a 63-year-old male who developed nonreversible symptomatic bradycardia due to advanced atrioventricular block (AV) requiring pacemaker placement in the setting of severe SARS-CoV-2 pneumonia. SARS-CoV-2 is a novel coronavirus identified as the pathogen responsible for causing th...

Triple Therapy for Persistent Pulmonary Hypertension Post Left Ventricular Assist Device: A Success Case for Cardiac Transplant

Muhammad O Zaman, MD, Luka Petrovic, MD, Scott Stewart, DNP and Bernard Kim, MD

Article Type: Case Report | First Published: February 24, 2021

Patients with end stage heart failure often develop pulmonary hypertension which resolves after placement of left ventricular assist device (LVAD). Some patients develop persistent pulmonary hypertension despite LVAD implantation. This excludes them from being able to receive a heart transplant. High pulmonary vascular resistance is associated with poor prognosis in patients with LVAD. There are no treatment guidelines available for long term treatment of pulmonary hypertension in LVAD patients ...

Mitochondrial Dynamics and Cardiovascular Risk: An Insight at the Molecular Level

Ivan Lozada Martinez, Daniela Torres Llinás and Andres Llamas Nieves

Article Type: Commentary | First Published: February 06, 2021

Mitochondria are cellular organelles; whose function goes beyond generating adenosine triphosphate (ATP). They are part of the machinery involved in the production of substances related to iron, sulfur, and heme group, involved in lipid metabolism, calcium homeostasis, heat generation, cell signaling, stem cell pathway determination, and apoptotic processes. A vast variety of pathologies have been related to mitochondrial deficit, within these, cardiovascular diseases. Mitochondrial dysfunction ...

Homocysteine Levels and Cardiovascular Risk: Potential Predictor of Morbidity and Mortality

Ivan Lozada Martinez, Daniela Torres Llinás and Andres Llamas Nieves

Article Type: Commentary | First Published: February 06, 2021

Homocysteine is a sulfurated amino acid, deriving out of methionine from the metabolism of the methyl group. It is a non-protein substance that has been associated with the dynamics of endothelial function, platelet activation, and leukocyte interaction, with the capacity to intensify the inflammatory response in the cardiovascular system, it is therefore considered a potential cardiovascular risk marker. Some studies have evaluated homocysteine in risk groups, where it has been found that the e...

Unjustified Referral of Adult Patients with Hypertensive Crisis from a First Level of Care to the Emergency Department

Rodriguez-Zuñiga Jorge, Garcia-Hernandez Jorge Alfredo, Lopez-Vilchis Lizeth Liliana, Ruiz-Mondragon Alberto and Sanchez-Martinez Fatima Alondra

Article Type: Original Article | First Published: January 23, 2021

Hypertensive crisis is one of the main complications of systemic arterial hypertension, which is defined as severe elevation of blood pressure, with figures of more than 220/130 mmHg, these in turn are divided into urgency and emergency, which occurs when there is damage to a target organ. According to the literature, the majority of hypertensive crises that occur are of an urgency type, reported in up to 80% of cases, the latter do not require a rapid decrease in blood pressure, taking up to 72...

The Influence of Iterative Reconstruction Technique on the Diagnosis of Coronary Artery Calcification

Ahmed Khamis AlShamakhi, MSc, Rakesh Malhari Jamkhandikar, MD, Yahya Mohammed AlWahshi, MD and Sathiya Murthi Panchatcharam, MSc

Article Type: Original Article | First Published: January 23, 2021

This study was performed in a single center and written informed consent was obtained from all patients. Thirty-one consecutive patients (26 men/5 women) underwent CT calcium score to rule out CAC. Image data were reconstructed with both; filtered back projection (FBP) and different levels of IR algorithms. Both the qualitative and quantitative image quality and subjective diagnostic performance were compared; Agatston scores and calcium density were measured for a total of 100 coronary arteries...
