Background: We aimed to investigate the short-term outcomes of heart transplant patients who underwent SherpaPak™ donor organ preservation.
Method: We prospectively collected the data of patients who underwent heart transplantation using SherpaPak™ system for donor organ transportation from February 2020 to March 2021. Donor and recipient demographic data, preoperative and postoperative echocardiographic and hemodynamic parameters, total ischemic time and SherpaPak temperatures, vasoactive inotropic scores (VIS), primary graft dysfunction (PGD) status, intensive care unit stay, complications, and mortality during follow-up were assessed.
Results: A total of 39 consecutive heart transplant patients with SherpaPak system were included in the study. The mean donor age was 32.2 ± 6.7 (range: 16-46). The mean recipient age was 57.5 ± 12 (range: 19-73). The mean preoperative ejection fraction (EF) was 23.7 ± 15.4 (range: 5-75). All recipients underwent a standard bicaval technique for orthotopic heart implantation. The mean total ischemic time was 230.1 ± 41 (range: 149-342) min. The mean Sherpa temperature was 5.6 ± 0.8°C (range: 3.7-7.5). The mean VIS was 10.2 ± 6.5 (range: 2-32). The number of mild PGD was 5 (14.7%), and moderate PGD was 4 (11.8%). There was no severe PGD. The postoperative EF was 64.3 ± 5.5 (range: 50-78). Mean intubation time was 47.4 ± 64 (range: 8-312, median: 22) h. The mean time of intensive care unit stay was 6.3 ± 5 (range: 2-31, median: 5) days. Two patients required chest revision (5.8%), two patients had lung infection (5.8%). Two patients had a stroke (5.8%). There was no mortality.
Conclusion: Using the SherpaPak system during heart transplantation is safe and not associated with significant recipient morbidity. None of the recipients experienced significant PGD and mortality.

Purpose Of Review: This review summarizes the current literature on primary graft dysfunction highlighting the current definition, reviewing epidemiology, and describing donor, recipient, and perioperative risk factors in the contemporary era.
Recent Findings: PGD, in its most severe form, complicates 8% of heart transplants and portends a 1-year mortality of close to 40%. PGD is multifactorial and heterogeneous with contributions from donor and recipient risk as well as organ recovery and preservation modalities.

Studies have shown that patients who undergo heart transplantation (HTx) are at an increased risk for developing skin cancer. This condition can add physiological and psychological burden to patients. Therefore, assessing the incidence and identifying risk factors for skin cancer are crucial steps in its prevention.

Myocarditis, a leading cause of sudden cardiac death and heart transplantation, poses significant treatment challenges. The study of clinical samples from myocarditis patients reveals a correlation between the pathogenesis of myocarditis and cardiomyocyte mitochondrial DNA (mtDNA). During inflammation, the concentration of mtDNA in cardiomyocytes increases.

We describe a 54-year-old man with type 2 diabetes mellitus, ischemic myopathy, pulmonary hypertension, and end-stage renal disease who was admitted for heart failure and listed for a dual cardiac-renal transplantation. Extensive calcification in the iliac arteries prevented clamping. Proximal endovascular balloon control of the left iliac artery was achieved using contralateral access; distal control was established by passing a Fogarty catheter distally through an iliac arteriotomy, later used for anastomosis of the cadaveric conduit.

Objective: Evaluate the relationship of cathepsin-D (CD) on disease severity and clinical outcomes for women with peripartum cardiomyopathy.
Background: Cathepsin-D is a protease released during oxidative stress that cleaves prolactin (PRL) generating a 16 kDa fragment that is pro-apoptotic, anti-angiogenic, and has been implicated in the pathogenesis of peripartum cardiomyopathy (PPCM).
Methods: In 99 women with newly diagnosed PPCM enrolled in the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study, CD levels were assessed by ELISA from serum obtained at study entry.
