The Uncertain Benefit from Implantable Cardioverter-Defibrillators in Nonischemic Cardiomyopathy: How to Guide Clinical Decision-Making?

Life-threatening dysrhythmias remain a significant cause of mortality in patients with nonischemic cardiomyopathy (NICM). Implantable cardioverter-defibrillators (ICD) effectively reduce mortality in patients who have survived a life-threatening arrhythmic event. The evidence for survival benefit of primary prevention ICD for patients with high-risk NICM on guideline-directed medical therapy is not as robust, with efficacy questioned by recent studies.

Clinical Interpretation of Genetic Variants in the Evaluation and Management of Thoracic Aortic Aneurysm and Dissection.

Background: We aimed to elucidate clinical implications of genetic variant interpretation in assessing disease severity and progression in thoracic aortic aneurysm and dissection (TAAD) patients.

Methods: Consecutive TAAD patients with aortic root and/or ascending aortic aneurysms seen between 2011 and 2020 were included. Serial echocardiography, family history of TAAD, and management information were retrospectively collected and analyzed.

Quality of life after robotic versus conventional minimally invasive cancer surgery: a systematic review and meta-analysis.

Optimizing postoperative quality of life (QoL) is an essential aspect of surgical oncology. Minimally invasive surgery (MIS) decreases surgical morbidity and improves QoL outcomes. This meta-analysis aimed to compare post-operative QoL after oncologic resections using different MIS modalities.

An assessment of public experiences and expectations with physicians: a cross sectional study from Karachi, Pakistan.

Background: Although physicians are highly regarded members of society, patients are not always satisfied with their care, suggesting a mismatch between the public's expectations and reality. Thus, the aim of this study was to determine the public's expectations regarding roles and responsibilities of a physician, to assess patient experiences, and to evaluate factors associated with the two outcomes.

Methods: A cross-sectional study was conducted via face-to-face structured interviews from July 14th to August 2nd, 2023, in Karachi, Pakistan.

Myocardial work indices in bileaflet mitral valve prolapse patients.

Aims: Mechanisms underlying left ventricular dysfunction and arrhythmogenesis in bileaflet mitral valve prolapse (BMVP) patients are not well defined. Myocardial work index (MWI) is a non-invasive assessment that correlates with myocardial oxygen consumption. We aimed to compare global and regional MWI in BMVP patients with normal controls.

Hypertrophic Cardiomyopathy-Septal Perforator Arteries Doppler Flow Dynamics.

Background: Patients with hypertrophic cardiomyopathy (HCM) have been shown to exhibit abnormal diastolic vessel flow; however, flow pattern profiles and their possible association with different grades of diastolic dysfunction have not been studied. Color Doppler two-dimensional echocardiography permits visualization of the septal perforator arteries, and pulsed-wave Doppler allows recording of diastolic septal artery flow (SAF). Through routine visualization of the septal perforator arteries and acquisition of SAF, we noticed 3 patterns of SAF in patients with HCM.
